Patent Description:
Dialysis is a treatment used to support a patient with insufficient renal function. The two principal dialysis methods are hemodialysis and peritoneal dialysis. During hemodialysis ("HD"), the patient's blood is passed through a dialyzer of a dialysis machine while also passing a dialysis solution or dialysate through the dialyzer. A semi-permeable membrane in the dialyzer separates the blood from the dialysate within the dialyzer and allows diffusion and osmosis exchanges to take place between the dialysate and the blood stream. These exchanges across the membrane result in the removal of waste products, including solutes like urea and creatinine, from the blood. These exchanges also regulate the levels of other substances, such as sodium and water, in the blood. In this way, the dialysis machine acts as an artificial kidney for cleansing the blood.

During peritoneal dialysis ("PD"), the patient's peritoneal cavity is periodically infused with dialysate. The membranous lining of the patient's peritoneum acts as a natural semi-permeable membrane that allows diffusion and osmosis exchanges to take place between the solution and the blood stream. These exchanges across the patient's peritoneum result in the removal of waste products, including solutes like urea and creatinine, from the blood, and regulate the levels of other substances, such as sodium and water, in the blood.

Continuous ambulatory peritoneal dialysis (CAPD) therapy involves hanging a bag of fresh dialysate and using gravity to fill a patient's peritoneal cavity. At the end of the dwell phase of the treatment cycle, the patient drains effluent (spent dialysate) from the patient's peritoneal cavity into a drain bag via gravity.

<CIT> describes a dialysis apparatus which includes water pre-treatment, a dialysate preparation and an extra corporeal circuit for circulating blood from a patient through a dialysis circuit and back to the patient.

<CIT> describes a mobile support assembly (e.g., cart) for a dialysis machine. The support assembly may be configured to determine one or more properties relating to a dialysis treatment being performed on a patient using the dialysis machine, and to control one or more actions that affect the dialysis treatment based at least in part on the determined one or more properties.

Implementations can include one or more of the following advantages.

In some implementations, a basin system enables rapid detection of a leakage from a medical fluid bag (e.g., a dialysate bag or a drain bag) being used during a medical treatment (e.g., a dialysis treatment). The basin system can also alert a user of the system if a leakage from the medical fluid bag is occurring. By automatically detecting leaks from fluid bags used during the treatment and alerting a user, corrective action to stop the leak can be quickly provided to prevent additional fluid leakage.

In some implementations, the basin system automatically detects and records the weight of fluid in a medical fluid bag being used during a medical treatment. By automatically detecting and recording the amount of fluid contained in the medical fluid bag, patient errors and measurement inaccuracies during data collection can be avoided.

In some implementations, the basin system can provide improved analysis of the clarity of a medical fluid. For example, in some implementations, a tray used to support a drain bag during a drain phase of a PD treatment includes one or more markings that can be used to visually determine the clarity of effluent contained in the drain bag. In some implementations, the basin system includes an effluent sensor to automatically detect effluent clarity. These improved systems for checking effluent clarity during a drain phase can lead to improved patient safety.

In some implementations, the basin system permits automated recording and transmission of treatment data. For example, a control unit of the basin system can automatically collect treatment data using one or more components of the basin system, and the control unit can automatically transmit the collected treatment data to one or more remote computing devices for storage and/or processing of the treatment data. By automatically collecting treatment data and transmitting treatment data to remote computing devices, patient errors and measurement inaccuracies during data collection can be avoided, and the overall treatment time can be reduced.

In some implementations, the basin system is designed to be portable. For example, the basin system can include one or more wheels, making the system easy to move between treatments.

In addition, the basin system can provide safe and effective heating of medical fluid contained in medical fluid bags. For example, the basin system can include a heating system that is configured to heat medical fluid contained in a medical fluid bag placed on a tray of the basin system. The heating system is configured to stop heating upon removal of the fluid bag from the tray. By automatically stopping the heating in response to the fluid bag being removed from the tray, efficiency of the heating system and patient safety is improved.

The details of certain implementations are set forth in the accompanying drawings and the description below.

<FIG> depicts a patient <NUM> receiving a peritoneal dialysis ("PD") treatment using a PD system <NUM>. The PD system <NUM> includes a dialysate bag <NUM> suspended from a stand <NUM>. A fluid line <NUM> connects the dialysate bag <NUM> to a transfer set <NUM> that is connected to the patient <NUM>. A drain bag <NUM> is fluidly connected to the transfer set <NUM> via fluid line <NUM>. The PD system <NUM> includes a basin system <NUM> on which the drain bag <NUM> is positioned during treatment.

The PD system <NUM> of <FIG> can be used to perform a continuous ambulatory peritoneal dialysis (CAPD) treatment. CAPD treatment typically begins by draining fluid from a patient's peritoneal cavity. Once the patient's peritoneal has been drained, the patient's peritoneal cavity is filled with a fluid (e.g., dialysate), which then dwells in the patient's peritoneal cavity. After delivering the dialysate to the patient's peritoneal cavity and permitting the dialysate to dwell in the peritoneal cavity for a predetermined period of time, the dialysate is drained from the peritoneal cavity. These processes of draining, filling, dwelling, and draining is repeated throughout a CAPD treatment cycle.

In order to drain fluid from the patient's peritoneal cavity, the PD system <NUM> includes a drain bag <NUM> that is fluidly connected to the patient's peritoneal catheter using the transfer set <NUM>. During the drain phase of the PD treatment, the drain bag <NUM> is coupled to the patient's transfer set <NUM> using a fluid line <NUM>, and fluid flows from the peritoneal cavity of the patient <NUM> into the drain bag <NUM> along fluid line <NUM>. The drain bag <NUM> is positioned on and supported by the basin system <NUM> during the drain phase of the PD treatment.

Once the patient's peritoneal cavity has been drained of fluid, the fill phase of the PD treatment can be performed by connecting the dialysate bag <NUM> filled with dialysate to the patient's peritoneal catheter using the transfer set <NUM>, and delivering about <NUM>-<NUM> liters of dialysate to the peritoneal cavity. As will be described in further detail herein, in some implementations, the dialysate in the dialysate bag <NUM> is heated prior to beginning the fill phase.

In order to fill the patient's peritoneal cavity with dialysate without the use of a pump, the dialysate bag <NUM> is positioned above the transfer set <NUM>, which allows for gravity filling of the patient's peritoneal cavity. By hanging the dialysate bag <NUM> on the stand <NUM>, the dialysate flows downwards via gravity along the fluid line <NUM> and into the transfer set <NUM>. A clamp <NUM> is provided along the fluid line <NUM> to control fluid flow from the dialysate bag <NUM> along the fluid line <NUM>. For example, once the dialysate bag <NUM> has been attached to the stand <NUM> and opposite ends of the fluid line <NUM> are coupled to the dialysate bag <NUM> and the transfer set <NUM>, which is coupled to the patient's peritoneal catheter, the clamp <NUM> along the fluid line <NUM> can be opened to allow dialysate to flow via gravity from the dialysate bag <NUM> along the fluid line <NUM>, through the transfer set <NUM> and the patient's catheter, and into the peritoneal cavity of the patient <NUM>.

As will be described in further detail herein, the basin system <NUM> can assist a user in performing the PD treatment. For example, during PD treatment, the patient <NUM> or another user typically monitors and records various data related to the treatment, such as the dialysate concentration, the dialysate expiry date, dialysate volume exchanged during treatment, fill start time, fill end time, dwell time, drain start time, drain end time, the amount of fluid drained during the treatment, the clarity of effluent drained during the treatment. As will be described in detail herein, the basin system <NUM> can be used to assist the patient <NUM> in monitoring and recording such data related to the PD treatment. The basin system <NUM> can also be used to heat dialysate fluid contained in the dialysate bag <NUM> prior to flowing the dialysate in the dialysate bag <NUM> to the peritoneum of the patient <NUM>, as will be described below.

<FIG> depicts an example basin system <NUM> for use during PD treatment. As can be seen in <FIG>, the basin system <NUM> includes a tray <NUM> and a basin <NUM>. The tray <NUM> is positioned on top of the basin <NUM> in order to support and position a fluid bag, such as the dialysate bag <NUM> or the drain bag <NUM>, over the basin <NUM> during a PD treatment. For example, during the drain phase of the PD treatment, the drain bag <NUM> is positioned on the tray <NUM> over the basin <NUM>, as depicted in <FIG>. During a dialysate heating step prior to the fill phase of the PD treatment, the dialysate bag <NUM> is positioned on the tray <NUM> over the basin <NUM>.

As depicted in <FIG> and <FIG>, the basin <NUM> includes a weight scale <NUM>, and the tray <NUM> is positioned over and in contact with the weight scale <NUM> during PD treatment. As will be described in further detail herein, the weight scale <NUM> can be used to measure the weight or changes in weight to the dialysate bag <NUM> and/or the drain bag <NUM> positioned on the tray <NUM> in order to determine various data for the treatment cycle. The data can include, for example, a drain start time, a drain end time, the length of time elapsed during the drain phase, and an amount of fluid drained from the patient, and a volume of fluid contained in a dialysate bag that is warmed prior to the fill phase of treatment using the basin system <NUM>.

<FIG> and <FIG> show the tray <NUM> that can be used to support the dialysate bag <NUM> and/or the drain bag <NUM> over the basin <NUM> during treatment. As can be seen in <FIG> and <FIG>, the tray <NUM> defines a number of openings <NUM> therethrough that allow fluid to flow through the tray <NUM> into the basin <NUM> when the tray <NUM> is positioned over the basin <NUM>. For example, if the drain bag <NUM> or the dialysate bag <NUM> positioned on the tray <NUM> has a leak, fluid leaked from the bag can flow through the openings <NUM> in the tray <NUM> into the basin <NUM>, and is collected in the basin <NUM>.

The tray <NUM> is curved along its length towards a central channel <NUM> through the tray <NUM>, as depicted in <FIG>. As a result of the curved shape of the tray <NUM>, fluid on the surface of the tray <NUM>, such as fluid leaked from a fluid bag positioned on the tray <NUM>, is directed by gravity towards the central channel <NUM> in the tray <NUM>, and is drained into the basin <NUM> through the central channel <NUM>. For example, the curved shape of the tray <NUM> causes fluid on the top surface of the tray between the openings <NUM> to be directed towards the central channel <NUM> and into the basin <NUM>. As will be described in further detail herein, in some implementations, the basin <NUM> includes a leak detection sensor, and channeling fluid that has been leaked onto the tray <NUM> into the basin <NUM> through the openings <NUM> and the central channel <NUM> allows for leaks in a fluid bag placed on the tray <NUM> (e.g., drain bag <NUM>) to be detected by the system <NUM>.

Referring to <FIG> and <FIG>, the tray <NUM> defines handles <NUM>, <NUM>. The handles <NUM>, <NUM> can be used to carry the tray <NUM> and to lift the tray <NUM> off of the basin <NUM> with ease, for example, during cleaning of the tray <NUM> and basin <NUM>.

The tray <NUM> also includes conductive core elements <NUM>, <NUM>. The conductive core elements <NUM><NUM> extend through the tray <NUM> and are positioned on the tray <NUM> to contact a fluid bag (e.g., the dialysate bag <NUM> or the drain bag <NUM>) positioned on the tray <NUM>. The conductive core elements <NUM>, <NUM> can interact with one or more heating elements in the basin <NUM> to heat fluid contained in the fluid bag positioned on the tray <NUM>. For example, the dialysate bag <NUM> can be placed on the tray <NUM> prior to performing the fill, and heating of the conductive core elements <NUM>, <NUM> by heating element(s) in the basin <NUM> can heat the dialysate contained in the bag, warming the dialysate fluid for use in the PD treatment.

As can be seen in <FIG> and <FIG>, the tray <NUM> includes contrast text <NUM> that allows a user of the basin system <NUM> to inspect the clarity of fluid contained within a fluid bag positioned on the tray <NUM>. For example, referring to <FIG> and <FIG>, during a PD treatment, the drain bag <NUM> can be placed on the tray <NUM> and the clarity of effluent drained from the patient <NUM> into the drain bag <NUM> can be visually inspected by the patient <NUM> (or another user of the system <NUM>) using the contrast text <NUM>. For example, the patient <NUM> or another user of the system <NUM> can check the clarity of the effluent drained from the patient <NUM> into the drain bag <NUM> by determining whether the drained effluent is sufficiently clear such that the contrast text <NUM> on the tray <NUM> is visible through the effluent in the drain bag <NUM>. If the contrast text <NUM> on the tray <NUM> is not visible through the effluent in the drain bag <NUM> due to cloudiness or discoloration of the effluent, this indicates that the patient <NUM> could be experiencing an infection, such as peritonitis. By checking the clarity of effluence drained from the patient <NUM> using the contrast text <NUM> on the tray <NUM>, the patient <NUM> or another user of the system <NUM> is quickly and easily alerted of potential infections that the patient <NUM> may be experiencing and can seek appropriate medical attention for the patient <NUM>. The contrast text <NUM> is printed on a surface of the tray <NUM> in a color that contrasts with the color of tray <NUM>.

<FIG> depicts the basin <NUM> of the basin system <NUM> of <FIG>. The basin <NUM> is configured to cooperate with the tray <NUM> of the system <NUM> in order to support fluid bags (e.g., dialysate bags <NUM> or drain bags <NUM>) placed on the tray <NUM> during PD treatment and collect any fluid leaking from the fluid bag placed on the tray <NUM>. A control unit <NUM> (e.g., a microprocessor) of the basin <NUM> can be used to record, store, and wirelessly transmit one or more parameters related to the PD treatment.

Still referring to <FIG>, the basin <NUM> includes a housing <NUM> that defines a chamber <NUM>. The chamber <NUM> is configured to collect fluids leaked onto the tray <NUM> and into the basin <NUM>. As depicted in <FIG>, the tray <NUM> of the basin system <NUM> is positioned over the chamber <NUM> and the dialysate bag <NUM> or the drain bag <NUM> (depending on the phase of the PD treatment) is placed on top of the tray <NUM>.

For example, during a dialysate heating step prior to the fill phase, the dialysate bag <NUM> is positioned on the tray <NUM> and the dialysate in the dialysate bag <NUM> is heated before being delivered to the patient. If the dialysate bag <NUM> includes a leak while positioned of the tray <NUM> for heating, dialysate will flow out of the dialysate bag <NUM>, through the openings <NUM> and central channel <NUM> of the tray <NUM>, and into the chamber <NUM> of the basin <NUM>. Once the dialysate in the dialysate bag <NUM> has been heated and no leaks from the bag <NUM> are detected, the dialysate bag <NUM> is removed from the tray <NUM> and is attached to stand <NUM> so that the dialysate can be provided to the patient via gravity during treatment.

During the draining phase of the PD treatment, the drain bag <NUM> is positioned on the tray <NUM> and effluent is drained from the patient <NUM> and flows into the drain bag <NUM>. If the drain bag <NUM> includes a leak, effluent will flow out of the drain bag <NUM>, through the openings <NUM> and central channel <NUM> of the tray <NUM>, and into the chamber <NUM> of the basin <NUM>.

Referring to <FIG> and <FIG>, the housing <NUM> of the basin <NUM> further defines a drain opening <NUM> that extends through the housing <NUM>. An expandable plug <NUM> can be inserted into the drain opening <NUM> in order to seal the drain opening <NUM> and prevent fluid from flowing out of the chamber <NUM> through the drain opening <NUM>. For example, during the PD treatment, the expandable plug <NUM> can be disposed in the drain opening <NUM> to prevent any fluid leaked from a fluid bag positioned on the tray <NUM> from flowing out of the chamber <NUM> of the basin <NUM>. The expandable plug <NUM> can be removed in order to drain fluid from the chamber <NUM> of the basin <NUM>, for example, in order to clean the basin <NUM>. Fluid collected in the chamber <NUM> is drained by positioning the basin <NUM> over a toilet, bathtub, or sink, and removing the expandable plug <NUM> from the drain opening <NUM> to allow the fluid in the chamber <NUM> to flow through the drain opening <NUM> into the toilet, bathtub, or sink.

As depicted in <FIG>, the bottom surface <NUM> of the chamber <NUM> slopes inwards towards the drain opening <NUM> in the chamber <NUM> to direct fluid leaked into the chamber <NUM> towards to drain opening <NUM>. By directing fluid in the chamber <NUM> towards the drain opening <NUM>, the curved bottom surface <NUM> of the chamber <NUM> allows for improved ease in draining fluid out of the chamber <NUM>. In some implementations, the bottom surface <NUM> of the chamber <NUM> is clear in order to allow a user to more easily inspect the color and clarity of effluent contained in a drain bag <NUM> positioned over the basin <NUM> (e.g., via a tray <NUM> coupled to the basin <NUM>).

The basin <NUM> also includes a leak detector <NUM> for detecting fluid that has leaked into the basin <NUM>. The leak detector <NUM> is positioned within the chamber <NUM> and includes a wetness sensor configured to detect when a fluid contacts the leak detector <NUM>. For example, if the fluid bag (e.g., the dialysate bag <NUM> or the drain bag <NUM>) positioned on the tray <NUM> leaks fluid (e.g., dialysate or effluent) onto the tray <NUM>, into the chamber <NUM> of the basin <NUM>, and into contact with the leak detector <NUM> in the chamber <NUM>, the leaked fluid will be automatically detected by the leak detector <NUM>.

The leak detector <NUM> is formed of conductive (e.g., metal) material that is configured to detect whenever a fluid, such as leaked dialysate or effluent, contacts the leak detector <NUM>. For example, as can be seen in <FIG> and <FIG>, in some implementations, the leak detector <NUM> is formed as two concentric metal rings <NUM>, <NUM> that are positioned within a channel formed between the scale <NUM> and the bottom surface <NUM> of the chamber <NUM>, with a first ring <NUM> serving as a positive terminal and a second ring <NUM> serving as a negative terminal. In addition, the bottom surface <NUM> of the chamber <NUM> is sloped to direct fluids leaked into the chamber <NUM> via gravity towards the leak detector <NUM>. Positioning the leak detector <NUM> within the chamber <NUM> such that the sloped bottom surface <NUM> of the chamber <NUM> directs fluid leaked from a fluid bag towards the leak detector <NUM> allows for prompt detection of any leaks in the fluid bag supported by the system <NUM>.

When electrically conductive fluid, such as dialysate or effluent, leaks into the chamber <NUM> and contacts the two metal rings <NUM>, <NUM> of the leak detector <NUM>, the leaked fluid bridges the gap between the metal rings <NUM>, <NUM> and allows electrical current to flow from positive to negative terminals to complete a circuit. In response to completion of the circuit formed by the leak detector, the leak detector <NUM> can generate a signal indicating that wetness has been detected in the basin <NUM> and transmit the signal to a computing device. For example, the leak detector <NUM> can be configured to transmit a signal to the control unit <NUM> of the basin <NUM> in response to fluid contacting the leak detector <NUM>. In response to receiving a signal from the leak detector <NUM> indicating a leak, the control unit <NUM> can generate an alert indicating that a leak in the fluid bag on the tray <NUM> has been detected by the system <NUM>. In response to the control unit <NUM> receiving a signal from the leak detector <NUM> indicating the presence of a fluid leak, the control unit <NUM> can control a graphical display <NUM> on the basin <NUM> to display a message or warning indicating that a fluid leak from the fluid bag has been detected by the system <NUM>. The control unit <NUM> can alternatively or additionally control a speaker <NUM> of the basin <NUM> to emit an audible alert indicating that a fluid leak has been detected by the system <NUM>.

Referring back to <FIG> and <FIG>, the basin <NUM> also includes a weight scale <NUM> configured to measure the weight of fluid contained in a fluid bag (e.g., the dialysate bag <NUM> or the drain bag <NUM>) positioned on the tray <NUM> of the basin system <NUM>. The weight scale <NUM> can include a load cell configured to measure the force applied onto the weight scale <NUM> by the tray <NUM> positioned on the weight scale <NUM> together with any objects positioned on the tray <NUM>, such as the drain bag <NUM> or the dialysate bag <NUM>.

The weight scale <NUM> is communicably coupled to the control unit <NUM> of the basin <NUM> and is configured to transmit signals to the control unit <NUM> indicating a weight detected by the weight scale <NUM>. For example, in order to determine an amount of fluid drained from the patient <NUM> during the drain phase of a PD treatment cycle, an empty drain bag <NUM> can be placed on the tray <NUM>, and the weight scale <NUM> can detect an incremental increase in weight applied to the weight scale <NUM> corresponding to a predetermined initial weight indicating that an empty drain bag <NUM> has been placed on the tray <NUM>. The weight corresponding to an empty drain bag <NUM> can be recorded and stored by the control unit <NUM> of the basin <NUM>. In response to the scale <NUM> detecting a weight indicating that an empty drain bag <NUM> has been placed on the tray <NUM>, the weight scale <NUM> can send a signal to the control unit <NUM> indicating the start time of the drain phase of the cycle and can begin measuring the weight of the tray and drain bag <NUM> as the drain phase proceeds.

Once the drain phase has ended, and thus no additional fluid has been added to the drain bag <NUM> for a predetermined amount of time, the weight scale <NUM> can detect that a predetermined amount of time has elapsed since any weight increases were detected by the scale <NUM> and, in response, can send a signal to the control unit <NUM> indicating an end time of the drain phase of the treatment cycle.

Based on the signals received from the weight scale <NUM>, the control unit <NUM> can determine the length of the drain phase of the PD treatment cycle. For example, the control unit <NUM> can calculate the amount of time elapsed between the time that the weight scale <NUM> transmitted a signal indicating an initial weight for the drain phase and the time that the weight scale <NUM> transmitted a signal indicating a final weight for the drain phase in order to determine the duration of the drain phase.

The control unit <NUM> can also use the signals received from the weight scale <NUM> to determine a total amount of fluid drained from the patient <NUM> during the PD treatment cycle. For example, the control unit <NUM> can calculate the difference between the final weight measured by the weight scale <NUM> during the drain phase of the treatment cycle and the initial weight measured by the weight scale <NUM> at the beginning of the drain phase of the treatment to determine a total weight of effluent drained from the patient <NUM> and captured in the drain bag <NUM> during the drain phase of the cycle.

In addition, the weight scale <NUM> can be used to determine a volume of dialysate contained in a dialysate bag <NUM> used during the fill phase of the PD treatment cycle. For example, before the beginning the fill phase of treatment, a dialysate bag <NUM> can be positioned on the tray <NUM> in order to warm the dialysate in the bag <NUM>, as will be described in further detail herein. As the dialysate bag <NUM> is being heated by the system <NUM>, the weight of a dialysate bag <NUM> positioned on the tray <NUM> can be automatically detected by the weight scale <NUM> and a signal can be transmitted from the weight scale <NUM> to the control unit <NUM> of the basin <NUM> indicating the initial weight of the dialysate bag <NUM>. Based on this weight detected by scale <NUM>, the volume of dialysate fluid in dialysate bag <NUM> can be determined by the control unit <NUM>. Once the dialysate in the dialysate bag <NUM> has been heated, the dialysate bag <NUM> is removed from the tray <NUM> and is attached to stand <NUM> so that the dialysate can be provided to the patient via gravity during treatment.

In some implementations, the system <NUM> is automatically turned on or awakened from a sleep mode in response to the weight scale <NUM> detecting a weight increase corresponding to either a full dialysate bag or an empty drain bag being placed on the tray <NUM>.

As depicted in <FIG> and <FIG>, the basin <NUM> includes an effluent sensor <NUM> configured to detect one or more characteristics of effluent contained in the drain bag <NUM> positioned on the tray <NUM> over the effluent sensor <NUM>. In some implementations, the effluent sensor <NUM> is optical sensor that is configured to transmit and detect light in the visible and/or UV spectrums. For example, the effluent sensor <NUM> can be an optical sensor configured to detect various colors of the effluent in drain bag <NUM> corresponding to various conditions including, but not limited to hemoperitoneam, chylous effluent, bile in the effluent, duodenal ulcer perforation, large bowel perforation, dye in effluent (e.g., resulting from fluorescein angiography), an icodextrin reaction with iodine, methemalbumin pancreatitis, and intravenous administration of dextran and Rifampicin. The effluent sensor <NUM> can also be used to determine the clarity of effluent drained from the patient <NUM>.

Referring to <FIG>, during or at the end of the drain phase of a PD treatment cycle, the effluent sensor <NUM> can be operated to determine the color and clarity of effluent contained in a drain bag <NUM> positioned on the tray <NUM> of the system <NUM>. In some cases, the effluent sensor <NUM> is controlled to scan the effluent in response to a user command to activate the effluent sensor <NUM> that is received through a graphical display <NUM> or a microphone <NUM> of the basin <NUM>.

The effluent sensor <NUM> is communicably coupled to the control unit <NUM> of the basin <NUM> and is configured to transmit a signal to the control unit <NUM> indicating one or more characteristics of effluent drained from the patient. For example, in response to the effluent sensor <NUM> scanning the effluent in the drain bag <NUM> positioned on the tray <NUM>, the effluent sensor <NUM> can transmit a signal (e.g., wired or wirelessly) to the control unit <NUM> of the basin <NUM> indicating one or more characteristics of the effluent, such as clarity and color. In some implementations, the control unit <NUM> records the effluent characteristics received from the effluent sensor <NUM> in local data storage. In some implementations, the control unit <NUM> transmits the effluent characteristics received from the effluent sensor <NUM> to one or more remote computing devices, such as remote data storage devices.

In some implementations, when the effluent sensor <NUM> has completed the scan of the drain bag <NUM>, the control unit <NUM> controls the graphical display <NUM> to display a message indicating the results of the effluent scan. In some implementations, when the effluent sensor <NUM> has completed the scan of the drain bag <NUM>, the control unit <NUM> controls the speakers to emit an audible message indicating the results of the effluent scan. By automatically monitoring effluent conditions using an effluent sensor <NUM> and notifying the patient or another user of the results of the effluent scan, patient safety can be improved through early detection of signs of infection.

As can be seen in <FIG>, the basin <NUM> also includes one or more heating elements <NUM>, <NUM>. The heating elements <NUM>, <NUM> can be used to heat fluid contained in a fluid bag positioned on the tray <NUM> of the system116. For example, before performing the fill phase of a PD treatment cycle, the fresh dialysate fluid in dialysate bag <NUM> is warmed to a predetermined temperature. In order to accomplish this pretreatment warming, a dialysate bag <NUM> can be placed on the tray <NUM> of the system <NUM>, and the heating elements <NUM>, <NUM> in the basin can transfer heat to the dialysate bag <NUM>, heating the dialysate fluid contained in the dialysate bag <NUM>.

The heating elements <NUM>, <NUM> can be controlled by the control unit <NUM> to provide heat at a particular temperature. For example, the control unit <NUM> can control the heating elements <NUM>, <NUM> to heat to a predetermined temperature for a predetermined amount of time. In some implementations, a user can input a temperature (e.g., using the graphical display <NUM> or the microphone <NUM> of the basin <NUM>), and the control unit <NUM> controls the heating elements <NUM>, <NUM> to heat to the user-specified temperature.

The basin system <NUM> can alert a user once the predetermined or user-specified temperature has been reached. For example, in some implementations, the system <NUM> includes temperature sensors (e.g., one or more thermistors) in contact with the dialysate bag <NUM>, such as temperature sensors positioned on tray <NUM> that detect the temperature of the fluid in dialysate bag <NUM> and transmit signals indicating the temperature of the dialysate to the control unit <NUM>. In response to receiving a signal from one or more temperature sensors indicating that the fluid in the dialysate bag <NUM> has reached the predetermined or user-specified temperature, the control unit <NUM> of the basin <NUM> can cause a visual alert to be displayed on the graphical display <NUM> or can cause the speakers <NUM> to emit an audible alert indicating that the dialysate in the bag <NUM> has been heated to the predetermined or user-specified temperature.

The heating elements <NUM>, <NUM> are configured to contact and heat the conductive core elements <NUM>, <NUM> extending through the tray <NUM>, which in turn heat a fluid contained inside a fluid bag positioned on the tray <NUM>. <FIG> and <FIG> depict schematic cross-sectional views of the basin system <NUM> showing the interaction of the heating elements <NUM>, <NUM> in the basin <NUM> with the conductive core elements <NUM>, <NUM> of the tray <NUM>. As can be seen in <FIG> and <FIG>, when the tray <NUM> is positioned over and coupled to the basin <NUM>, the conductive core elements <NUM>, <NUM> are aligned with and positioned over the heating elements <NUM>, <NUM> of the basin <NUM>. Contact between the conductive core elements <NUM>, <NUM> and the heating elements <NUM>, <NUM> when the heating elements <NUM>, <NUM> are activated causes the temperature of the conductive core elements <NUM>, <NUM> to rise, which heats the fluid contained in any fluid bag positioned on the tray <NUM>.

The basin includes depressible members <NUM>, <NUM> to control contact between the conductive core elements <NUM>, <NUM> and the heating elements <NUM>, <NUM>. The depressible members <NUM>, <NUM> can include, but are not limited to, coil springs, leaf springs, wave springs, or torsion springs. The depressible members <NUM>, <NUM> are positioned within the chamber <NUM> of the basin <NUM> and contact the tray <NUM> when the tray <NUM> is positioned over and coupled to the basin <NUM>. As can be seen in <FIG>, when the tray <NUM> is empty or is supporting a small amount of weight, such as an empty fluid bag, the depressible members <NUM>, <NUM> remain in an expanded configuration, which prevents the conductive core elements <NUM>, <NUM> from contacting the heating elements <NUM>, <NUM> in the basin <NUM>. When a threshold amount force is applied to the tray <NUM>, the depressible members <NUM>, <NUM> are compressed (as depicted in <FIG>), which causes the conductive core elements <NUM>, <NUM> to come into contact with the heating elements <NUM>, <NUM> in the basin <NUM>. Whenever the heating elements <NUM>, <NUM> are activated, contact between the conductive core elements <NUM>, <NUM> and the heating elements <NUM>, <NUM>, as shown in <FIG>, heats the conductive core elements <NUM>, <NUM>. In some implementations, the threshold amount of force required to compress the depressible members <NUM>, <NUM> corresponds to the force applied by a full or nearly full fluid bag positioned on the tray <NUM> (e.g., dialysate bag <NUM> in <FIG>).

Once a threshold amount of force applied to the tray <NUM> is removed, the depressible members <NUM>, <NUM> return to their expanded state causing the conductive core elements <NUM>, <NUM> to no longer contact the heating elements <NUM>, <NUM>. For example, by removing a dialysate bag <NUM> from the tray <NUM>, depressible members <NUM>, <NUM> return to their expanded state and separate the conductive core elements <NUM>, <NUM> from the heating elements <NUM>, <NUM>, as depicted in <FIG>. By preventing the conductive core elements <NUM>, <NUM> in the tray <NUM> from contacting the heating elements <NUM>, <NUM> when the tray <NUM> is empty, fluid bags can be safely heated with a reduced risk of injury (e.g., burns) to the users of the system <NUM>.

For example, when a fresh dialysate bag <NUM> is placed on the tray <NUM>, the depressible members <NUM>, <NUM> are compressed and the conductive core elements <NUM>, <NUM> contact the heating elements <NUM>, <NUM>, causing the heating elements <NUM>, <NUM> to heat the conductive core elements <NUM>, <NUM> when the heating elements <NUM>, <NUM> are activated. As the heating elements <NUM>, <NUM> heat the conductive core elements <NUM>, <NUM>, heat is transferred from the conductive core elements <NUM>, <NUM> to the dialysate in the dialysate bag <NUM>, heating the dialysate. Once the dialysate bag <NUM> has been heated to the desired temperature for treatment, the dialysate bag <NUM> is removed from the tray <NUM>, which causes the depressible members <NUM>, <NUM> return to their expanded state (as depicted in <FIG>) and, as a result, raises the conductive core elements <NUM>, <NUM> out of contact with the heating elements <NUM>, <NUM>.

In addition, in some implementations, the heating elements <NUM>, <NUM> are automatically deactivated when a force above a threshold force is no longer being applied to the tray <NUM>. For example, when a dialysate bag <NUM> has been heated and is removed from the tray <NUM>, as depicted in <FIG>, the weight scale <NUM> detects the reduction in weight caused by the removal of the dialysate bag <NUM> and transmits a signal to the control unit <NUM> indicating the updated, reduced weight. In response to receiving the signal from the weight scale <NUM> indicating the reduced weight, the control unit <NUM> deactivates the heating elements <NUM>, <NUM>. By deactivating the heating elements <NUM>, <NUM> in response to the fluid bag being removed from the tray <NUM>, fluid bags can be safely heated with reduced risk of injury (e.g., burns) to the user of the system <NUM>.

The heating elements <NUM>, <NUM> in the basin <NUM> can be induction heating elements that comprise an induction coil. For example, the induction coil of the heating elements <NUM>, <NUM> can generate a magnetic field that is passed onto the conductive core elements <NUM>, <NUM> when the conductive core elements <NUM>, <NUM> are in contact with the heating elements <NUM>, <NUM>, which in turn heats the conductive core elements <NUM>, <NUM>. By using induction heating elements <NUM>, <NUM>, the conductive core elements <NUM>, <NUM> are only heated above room temperature when in contact with the heating elements <NUM>, <NUM> and the rest of the system <NUM>, including the heating elements <NUM>, <NUM>, remain at room temperature during the heating process. As such, fluid bags can be quickly and safely heated with reduced risk of injury (e.g., burns) to the user of the system <NUM>.

The basin <NUM> also includes one or more light emitting diodes (LEDs) <NUM> to indicate when a fluid bag is being heated by the system <NUM>. For example, when a fluid bag (such as dialysate bag <NUM>) is positioned in the tray <NUM> (as determined based on signals transmitted by weight scale <NUM>) and the heating elements <NUM>, <NUM> are activated, one or more LEDs <NUM> on the basin <NUM> are illuminated to indicate that the fluid bag is being heated by the basin <NUM>. Once the fluid bag is removed from the tray <NUM>, as determined based on a decrease in weight measured by the weight scale <NUM>, or once the heating elements <NUM>, <NUM> are deactivated, the LED(s) <NUM> are turned off.

Referring back to <FIG>, the basin <NUM> includes wheels <NUM>, <NUM>, <NUM>, <NUM> that allow for easy movement of the system <NUM>. Each wheel is coupled to the bottom surface <NUM> of the basin <NUM> proximate a respective corner of the basin <NUM>. The wheels <NUM>, <NUM>, <NUM>, <NUM> can be full-swivel wheels. In some cases, one or more of the wheels <NUM>, <NUM>, <NUM>, <NUM> include a locking caster that can be engaged to lock the respective wheels <NUM>, <NUM>, <NUM>, <NUM> and temporarily prevent movement of the basin <NUM> (e.g., during treatment).

Referring to <FIG>, the basin <NUM> includes a power adapter <NUM> that can be used to connect the basin <NUM> a power supply in order to provide power to one or more components of the basin <NUM>. The basin <NUM> can include a rechargeable battery that is used to power various components of the basin <NUM>, such as the weight scale <NUM>, the effluent sensor <NUM>, and the control unit <NUM>. The battery can be charged by connecting the power adapter <NUM> to a power supply (e.g., using a cable). In some implementations, the power adapter <NUM> is a <NUM> Watt power adaptor. The basin <NUM> also includes a switch <NUM> for turning the electronic components of the basin <NUM> on and off.

As can be seen in <FIG>, the basin <NUM> also includes ports <NUM>, <NUM> configured to couple to electronic devices. For example, the ports <NUM>, <NUM> can be configured to interface with a portable memory device, such as a universal serial bus (USB) storage device or other flash memory card, to store one or more treatment parameters captured by the system <NUM> onto the storage device. For example, the control unit <NUM> can transmit one or more treatment parameters received and recorded by the control unit <NUM> to a portable memory device coupled to one of the ports <NUM>, <NUM> on the basin <NUM>. In some implementations, the control unit <NUM> is configured to generate a treatment report containing all treatment parameters for the most recent PD treatment performed using the system, and export the treatment report onto a portable memory device coupled to one of the ports <NUM>, <NUM> on the basin <NUM>.

Referring to <FIG>, the PD system <NUM> includes a flow sensor <NUM> that is configured to measure the fluid flowing from the dialysate bag <NUM> into the patient's peritoneal cavity during the fill phase of the treatment cycle. The flow sensor <NUM> can be coupled to the fluid line <NUM> between the dialysate bag <NUM> and the transfer set <NUM> to measure fluid flow along the fluid line <NUM>. The flow sensor <NUM> detects and records a time when flow through the fluid line 106is first sensed (corresponding to the start time of the fill phase) and a time when flow along the fluid line <NUM> stops (corresponding to the end time of the fill phase). During the fill phase, the flow sensor <NUM> measures the amount of dialysate fluid that is provided to the patient <NUM> during the fill phase via fluid line <NUM>.

At the end of the fill phase of the PD treatment, a user can connect the flow sensor <NUM> to a port <NUM>, <NUM> on the basin <NUM>, and the flow data captured by the flow sensor <NUM> can be transmitted to the control unit <NUM> of the basin <NUM>. Based on the data provided by the flow sensor <NUM>, the control unit <NUM> can determine various parameters for the fill phase of the treatment, including a fill start time, a fill end time, an amount time elapsed during the fill phase, and an amount (e.g., volume) of fill fluid provided to the patient <NUM> during the fill phase. In some implementations, the control unit <NUM> transmits the treatment data determined based on the data received from the flow sensor <NUM> to one or more remote computing devices.

In some implementations, the control unit <NUM> can compare the data regarding fill volume received from the flow sensor <NUM> during the fill phase with data indicating an amount drained from the patient during the drain phase (e.g., based on data received from weight scale <NUM>) to determine ultrafiltration efficacy for the treatment cycle. For example, the difference between the fill volume measured by the flow sensor and the amount of fluid drained from the based determined based on data received from the weight scale <NUM> indicates the additional amount of fluid drained from the patient during the drain phase, which can be used to analyze the ultrafiltration efficiency of the treatment.

In some implementations, the control unit <NUM> determines an end time for the fill phase of the cycle based on the received flow sensor <NUM> data, and, based on the fill phase end time, the basin <NUM> generates an alert after a predetermined amount of time has elapsed from the fill end time indicating to a user that the dwell period is complete. For example, after a predetermined amount of time corresponding to the dwell time has elapsed from the fill phase end time, the control unit <NUM> can control the graphical display <NUM> to display an alert indicating that the dwell phase is complete and the drain phase can begin. In some implementations, after a predetermined amount of time corresponding to the dwell time has elapsed from the fill phase end time, the control unit <NUM> can control the speaker <NUM> to emit an audible alert indicating that the dwell phase is complete and the drain phase can begin.

The control unit <NUM> can utilize the data received from the flow sensor <NUM> and the weight scale <NUM> to determine a dwell time performed during the treatment cycle. For example, the end time for the fill cycle can be determined based on data indicating the time that the flow sensor <NUM> stopped detecting flow along the fluid line <NUM> between the dialysate bag <NUM> and transfer set <NUM>. Similarly, the start time of the drain cycle can be determined based on the first weight increase above a threshold amount recorded by the weight scale <NUM> after the end of the fill phase. The control unit <NUM> can then determine the total dwell time based on the time elapsed between the fill phase end time and the drain phase start time determined from the data received from the flow sensor <NUM> and the weight scale <NUM>.

As previously discussed, the graphical display <NUM> (shown in <FIG>) can be configured to display messages to a user of the basin system <NUM>, such as alarms and warning messages. In some implementations, the control unit <NUM> controls the graphical display <NUM> to display messages and alerts in response to the control unit <NUM> receiving signals from one or more sensing elements of the basin <NUM>, such as the leak detector <NUM>, the weight scale <NUM>, or the effluent sensor <NUM>.

The graphical display <NUM> can be a touchscreen display and can be used to display a graphical user interface. A user can interact with the graphical user interface displayed on the graphical display <NUM> to control the operation of one or more components of the basin <NUM>, such as controlling the weight scale <NUM> to take a weight measurement or controlling the effluent sensor <NUM> to analyze effluent contained in a drain bag <NUM> positioned on the tray <NUM>.

In addition, a user can use the graphical user interface displayed on the graphical display <NUM> to enter data related to the PD treatment, such as the clarity of the effluent drained from the patient during the drain phase, the concentration of the dialysate fluid used for the fill phase, the start time of the fill phase, the end time of the fill phase, the expiry date of the dialysate used for the fill phase, the volume of dialysate to be provided to the patient during the fill phase, clarity of the dialysate used for the fill phase. The treatment data input by the user using the graphical display <NUM> are received by the control unit <NUM> of the basin <NUM>, and the control unit <NUM> can transmit the treatment data to one or more remote computing devices for storage and evaluation.

The graphical user interface displayed on the graphical display <NUM> can also be used to access treatment history. For example, a patient's previous treatment history can be displayed on the graphical display <NUM> of the basin <NUM>. In some implementations, in response to a user's request for treatment history (e.g., input by the user using the graphical display <NUM>), the control unit <NUM> communicates wirelessly with one or more remote storage devices to retrieve the patient's treatment history and controls the graphical display <NUM> to visually display the retrieved treatment history data. In some implementations, the patient's treatment history is encrypted, and a user must provide credentials in order to access the encrypted treatment data. For example, the user can provide credentials via a GUI displayed on the graphical display <NUM> or via voice control using microphone <NUM>. The credentials required to retrieve encrypted treatment data can include a patient identification number, a password, a fingerprint, or retinal scan data.

The speaker <NUM> and microphone <NUM> of the basin can be used together to gather treatment data from a user of the system <NUM>. For example, the speaker <NUM> can be controlled to audibly emit one or more questions regarding various treatment data, and the microphone <NUM> can be used to capture the user's response to each question emitted by the speaker <NUM>. In some implementations, the speaker <NUM> is controlled to emit one or more treatment data questions in response to the control unit <NUM> receiving a signal from the weight scale <NUM> indicating a fluid bag (e.g., dialysate bag <NUM> or drain bag <NUM>) has been placed on the tray <NUM>.

The user input treatment parameters captured by the microphone <NUM> can be received by the control unit <NUM> and transmitted to one or more remote computing devices. For example, the speaker <NUM> of the basin <NUM> can be controlled to emit questions regarding the clarity of the effluent drained from the patient during the drain phase, the concentration of the dialysate used for the fill phase, the expiry date of the dialysate fluid used for the fill phase, the start time of the fill phase, the end time of the fill phase, the volume of dialysate to be provided to the patient during the fill phase, and the clarity of the dialysate used for the fill phase, and the user's response can be captured by the microphone <NUM> and processed by the control unit <NUM> of the basin <NUM>.

In addition, a user can use the microphone <NUM> to provide audible instructions for controlling one or more elements of the basin <NUM>, such as the weight scale <NUM>, the heating elements <NUM>, <NUM>, and the effluent sensor <NUM>. The user's audible instructions for controlling one or more components of the basin <NUM> can be captured by the microphone <NUM> and transmitted to the control unit <NUM>, which controls the corresponding components of the basin <NUM> in response to the user's audible instructions. The use of the microphone <NUM> for capturing treatment data and user instructions is especially useful for users of the system <NUM> with visual impairments that prevent the user from being able to see and interact with a graphical display.

As previously discussed, the speaker <NUM> on the basin <NUM> can be used to audibly emit warnings or alarms generated by the control unit <NUM>. Providing audible warnings and alarms using the speaker <NUM> in addition to or in lieu of visual warnings (e.g., displayed on graphical display <NUM>) is particularly beneficial for users with visual impairments that prevent the users from seeing warnings displayed on a graphical display.

The control unit <NUM> (e.g., a microprocessor) of the basin <NUM> is connected to the weight scale <NUM>, the leak detector <NUM>, the effluent sensor <NUM>, the heating elements <NUM>, <NUM>, the graphical display <NUM>, the speaker <NUM>, and the microphone <NUM> such that the control unit <NUM> can receive signals from and transmit signals to these components of the system in order to control operation of the basin <NUM> components and record treatment data. For example, in response to receiving one or more signals (e.g., from the weight scale <NUM> or the leak detector <NUM>) the control unit <NUM> can control the graphical display <NUM> to a visual alert and/or control the speaker <NUM> to emit an audible alert.

The control unit <NUM> can receive treatment data from various sensors of the basin <NUM>, including the weight scale <NUM>, the leak detector <NUM>, and the effluent sensor <NUM>, as well as user-inputted data treatment received from the graphical display <NUM> and microphone <NUM>. In some implementations, the control unit <NUM> automatically transmits the treatment data received from the sensors <NUM>, <NUM>, <NUM>, the graphical display <NUM>, and/or the microphone <NUM> to one or more remote computing devices. For example, the control unit <NUM> can transmit the received treatment data to a cloud computing device for storage. In some implementations, the control unit <NUM> transmits the received treatment data to one or more remote computing devices for display on the remote computing devices. For example, the control unit <NUM> can transmit the received treatment data to a mobile device of the patient for display on the patient's mobile device. In some examples, the control unit <NUM> transmits the received treatment data to a remote computing device operated by medical personnel assisting with the treatment for display at the remote computing device. In some implementations, the treatment data is wirelessly transmitted by the control unit <NUM> to one or more remote computing devices in real time.

In some implementations, the control unit <NUM> processes the received treatment data to generate a treatment report. The treatment report generated by the control unit <NUM> can include one or more of: drain start time, drain end time, the amount of fluid drained during the treatment, the clarity of effluent drained during the treatment, weight of the filled drain bag(s) <NUM> (e.g., as measured by weight scale <NUM>), time elapsed between drain bag checks, dwell time, dialysate volume exchanged during treatment, dialysate temperature, fill start time, fill end time, initial treatment start time (e.g., for the day), final treatment end time (e.g., for the day), and a total number of cycles performed during the day. In some implementations, the treatment report generated by the control unit <NUM> is wirelessly transmitted to one or more remote computing devices. For example, the control unit <NUM> can be configured to automatically transmit the treatment report to one or more remote computing devices (e.g., remote storage devices and/or remote computing devices of medical personnel or patients) at a predetermined time each day. In some implementations, the control unit <NUM> stores the treatment report on a portable memory device (e.g., a USB device) coupled to a port <NUM>, <NUM> of the basin.

<FIG> is a flowchart showing a method <NUM> of detecting a fluid leak from a drain bag during PD treatment. Prior to performing the drain phase of a PD treatment cycle, a fluid bag (e.g., drain bag <NUM>) is positioned on a tray (e.g., tray <NUM>) coupled to a basin device (e.g., basin <NUM>) (<NUM>). The fluid bag is fluidly coupled to the patient's peritoneal cavity (e.g., using transfer set <NUM> and fluid line <NUM>).

Once the fluid bag is positioned on the tray, effluent is flowed into the fluid bag during a PD treatment (<NUM>). For example, fluid can be flow from the patient's peritoneal cavity into the fluid bag during a drain phase of the PD treatment. In some implementations, fluid is flowed into the fluid bag via gravity (e.g., as depicted in <FIG>).

As discussed above, the tray includes markings (e.g., contrast text <NUM>) and/or a sensor (e.g., effluent sensor <NUM>) that can be used to determine the clarity of the fluid being flowed into the fluid bag. In some implementations, the basin includes a load cell (e.g., weight scale <NUM>) to measure the weight of the fluid being flowed into the fluid bag.

If a leakage in the fluid bag occurs as fluid is flowed into the fluid bag positioned on the tray, a leak sensor coupled to a surface of the basin device (e.g., leak detector <NUM>) detects the leakage (<NUM>). For example, in some implementations, the tray supporting the fluid bag includes one or more openings (e.g., openings <NUM>) or channels (e.g., central channel <NUM>) to direct fluid leaked from the fluid bag on the tray into the basin. In some implementations, the tray has a curved profile to direct fluid leaked onto the tray towards a central channel in the tray (e.g., central channel <NUM>) and into the basin. In some implementations, the leak detector is a wetness detector, and contact between the leaked fluid in the basin and the leak detector causes the leak detector to identify the leak and transmit a signal to a control unit (e.g., control unit <NUM>) of the basin indicating the presence of a leak. In some implementations, the basin defines a chamber (e.g., chamber <NUM>) to contain the leaked fluid and an inner surface of the basin (e.g., surface <NUM>) is sloped to direct fluid contained in the basin towards the leak detector.

In response to receiving a signal from the leak detector indicating a leak has occurred, a control unit of the basin device (e.g., control unit <NUM>) automatically transmits treatment data, including data indicating the occurrence of a fluid bag leak, to a remote computing device (<NUM>). For example, the control unit can wirelessly transmit treatment data to one or more computing devices for storage or display of the treatment data at the one or more remote computing devices. In some implementations, treatment data received by the control unit, including the data received from the leak detector, is transmitted in real time from the control unit of the basin to the remote computing device. The treatment data transmitted from the control unit to the remote computing device can include one or more of: drain start time, drain end time, the amount of fluid drained during the treatment, the clarity of effluent drained during the treatment, weight of the filled drain bag(s) <NUM> (e.g., as measured by weight scale <NUM>), time elapsed between drain bag checks, dwell time, dialysate volume exchanged during treatment, dialysate temperature, fill start time, fill end time, initial treatment start time (e.g., for the day), final treatment end time (e.g., for the day), and a total number of cycles performed during the day.

For example, referring to <FIG>, the control unit <NUM> of the basin system <NUM> could be an example of the system <NUM> described here. The system <NUM> includes a processor <NUM>, a memory <NUM>, a storage device <NUM>, and an input/output interface <NUM>. Each of the components <NUM>, <NUM>, <NUM>, and <NUM> can be interconnected, for example, using a system bus <NUM>. The processor <NUM> is capable of processing instructions for execution within the system <NUM>. The processor <NUM> can be a single-threaded processor, a multi-threaded processor, or a quantum computer. The processor <NUM> is capable of processing instructions stored in the memory <NUM> or on the storage device <NUM>. The processor <NUM> may execute operations such as receiving signals from a sensing element (e.g., the leak detector <NUM>, the weight scale <NUM>, and the effluent sensor <NUM> shown in <FIG>) and transmitting the signal received from the sensing element to a remote computing device or storage device.

In some implementations, the memory <NUM> is a computer-readable medium. The memory <NUM> can, for example, be a volatile memory unit or a non-volatile memory unit. In some implementations, the memory <NUM> stores a data structure. In some implementations, multiple data structures are used.

In some implementations, the storage device <NUM> is a non-transitory computer-readable medium. The storage device <NUM> can include, for example, a hard disk device, an optical disk device, a solid-date drive, a flash drive, magnetic tape, or some other large capacity storage device. The storage device <NUM> may alternatively be a cloud storage device, e.g., a logical storage device including multiple physical storage devices distributed on a network and accessed using a network.

The input/output interface <NUM> provides input/output operations for the system <NUM>. In some implementations, the input/output interface <NUM> includes one or more of network interface devices (e.g., an Ethernet card), a serial communication device (e.g., an RS-<NUM><NUM> port), and/or a wireless interface device (e.g., an <NUM> card, a <NUM> wireless modem, a <NUM> wireless modem, a <NUM> wireless modem, or better). In some implementations, the input/output device includes driver devices configured to receive input data and send output data to other input/output devices, e.g., keyboard, printer and display devices <NUM>. In some implementations, mobile computing devices, mobile communication devices, and other devices are used.

In some implementations, the system <NUM> is a microcontroller. A microcontroller is a device that contains multiple elements of a computer system in a single electronics package. For example, the single electronics package could contain the processor <NUM>, the memory <NUM>, the storage device <NUM>, and input/output interfaces <NUM>.

Although an example processing system has been described in <FIG>, implementations of the subject matter and the functional operations described above can be implemented in other types of digital electronic circuitry, or in computer software, firmware, or hardware, including the structures disclosed in this specification and their structural equivalents, or in combinations of one or more of them. Implementations of the subject matter described in this specification can be implemented as one or more computer program products, i.e., one or more modules of computer program instructions encoded on a tangible program carrier, for example a computer-readable medium, for execution by, or to control the operation of, a processing system. The computer readable medium can be a machine readable storage device, a machine readable storage substrate, a memory device, a composition of matter effecting a machine readable propagated signal, or a combination of one or more of them.

The term "computer system" may encompass all apparatus, devices, and machines for processing data, including by way of example a programmable processor, a computer, or multiple processors or computers. A processing system can include, in addition to hardware, code that creates an execution environment for the computer program in question, e.g., code that constitutes processor firmware, a protocol stack, a database management system, an operating system, or a combination of one or more of them.

A computer program (also known as a program, software, software application, script, executable logic, or code) can be written in any form of programming language, including compiled or interpreted languages, or declarative or procedural languages, and it can be deployed in any form, including as a standalone program or as a module, component, subroutine, or other unit suitable for use in a computing environment.

Computer readable media suitable for storing computer program instructions and data include all forms of non-volatile or volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks or magnetic tapes; magneto optical disksand CD-ROM and DVD-ROM disks.

A number of embodiments have been described. Nevertheless, it will be understood that various modifications may be made without departing from the scope of the claims.

For example, while the basin system <NUM> has been described as being used during a CAPD treatment, the basin system <NUM> can also be used during automated peritoneal dialysis (APD) treatments. During APD treatment, automated PD machines called PD cyclers control the entire PD process so that it can be performed at home usually overnight without clinical staff in attendance. Many PD cyclers are designed to automatically infuse, dwell, and drain dialysate to and from the patient's peritoneal cavity. APD treatment typically lasts for several hours, often beginning with an initial drain cycle to empty the peritoneal cavity of used or spent dialysate.

<FIG> depicts an example PD cycler <NUM> seated on a cart <NUM>. The PD cycler <NUM> includes a housing <NUM>, a door <NUM>, and a cassette interface that contacts a disposable PD cassette when the cassette is disposed within a cassette compartment formed between the cassette interface and the closed door <NUM>. Dialysate bags <NUM> are suspended from fingers on the sides of the cart <NUM>. The dialysate bags <NUM> are connected to the cassette via dialysate bag lines <NUM>. The dialysate bag lines <NUM> can be used to pass dialysate from dialysate bags <NUM> to the cassette during a fill phase of an APD treatment cycle. A patient line <NUM> and a drain line <NUM> are connected to the cassette. The patient line <NUM> can be connected to a patient's abdomen via a catheter and can be used to pass dialysate back and forth between the cassette and the patient's peritoneal cavity during use. The drain line <NUM> can be connected to drain bag <NUM> positioned on the basin system <NUM> and can be used to pass dialysate from the cassette to the drain bag <NUM> during use.

As described above, the basin system <NUM> can be used to measure and record one or more treatment data related the PD treatment, such as drain start time, drain end time, the amount of fluid drained during the treatment, the clarity of effluent drained during the treatment, dwell time, dialysate volume exchanged during treatment. In addition, as described herein, the basin system <NUM> can be used to detect and contain any leaks in the drain bag <NUM> that occur during the treatment. The treatment data collected by the basin system <NUM> can be used to confirm the accuracy of similar treatment data collected by the cycler <NUM> and can be used to calibrate the cycler <NUM>. In some implementations, basin systems <NUM> used in conjunction with a cycler <NUM> during APD treatment have a larger tray <NUM> and basin <NUM> compared to systems <NUM> used during CAPD treatments in order to accommodate the larger and/or greater number of drain bags used during APD treatments.

In some implementations, drain bag(s) <NUM> used during APD are connected to hooks on cart <NUM> to support the drain bag(s) <NUM>, and the basin system <NUM> is positioned underneath and in contact with the drain bag(s) <NUM>. In some implementations, basin systems <NUM> used for APD treatments do not include a heating system (e.g., conductive core elements <NUM>, <NUM> and heating elements <NUM>, <NUM>), as dialysate is automatically warmed by the cycler <NUM>.

While the heating elements <NUM>, <NUM> have been described as being automatically activated and deactivated based on signals received from the weight scale <NUM>, other means of controlling the heating elements <NUM>, <NUM> are possible. For example, in some implementations, the heating elements <NUM>, <NUM> are controlled based on user input received by the control unit <NUM>. For example, the user can use the graphical display <NUM> or the microphone <NUM> of the basin <NUM> to provide instructions to activate or deactivate the heating elements <NUM>, <NUM>. In some implementations, a user can set a temperature of the heating elements <NUM>, <NUM> using the graphical display <NUM> or the microphone <NUM> of the basin <NUM>. In some implementations, the system includes a mechanical switch that is activated when a predetermined amount of force is placed on the tray <NUM>, such as when a dialysate bag <NUM> is placed on the tray <NUM>, and the control unit <NUM> activates the heating elements <NUM>, <NUM> in response to activation of the mechanical switch.

In some implementations, a magnet is positioned within the basin <NUM> and the system <NUM> includes a Hall effect sensor to control activation of the heating elements <NUM>, <NUM>. For example, when a threshold force is applied to the tray <NUM> (for example, by positioning a dialysate bag <NUM> on the tray <NUM>), the conductive core elements <NUM>, <NUM> are lowered into proximity of the magnet in the basin <NUM>, which causes the Hall effect sensor to transmit a sensor to control unit <NUM>. In response to receiving a signal from the Hall effect sensor indicating that a force has been applied to the tray <NUM>, the control unit <NUM> activates the heating elements <NUM>, <NUM> to heat the conductive core elements <NUM>, <NUM>.

In some implementations, the system <NUM> includes one or more ultrasonic range detectors and/or optical or laser detectors configured to measure the distance between the tray <NUM> and the bottom surface <NUM> of the basin <NUM> in order to control activation of the heating elements <NUM>, <NUM>. For example, when a threshold force is applied to the tray <NUM> that causes the tray <NUM> to be lowered within a threshold distance of the bottom surface <NUM> of the basin <NUM> (for example, by positioning a dialysate bag <NUM> on the tray <NUM>), the ultrasonic, optical, or laser sensor(s) transmit a signal to control unit <NUM>. In response to receiving a signal from the ultrasonic, optical, or laser sensor(s), the control unit <NUM> activates the heating elements <NUM>, <NUM> to heat the conductive core elements <NUM>, <NUM>. Similarly, in some implementations, the system <NUM> includes one or more optical detectors configured to detect an air gap between the bottom of the tray <NUM> and the bottom surface <NUM> of the basin <NUM>, and when a threshold force is applied to the tray <NUM> causing the tray <NUM> to be lowered into contact with the bottom surface <NUM> of the basin <NUM> (for example, by positioning a dialysate bag <NUM> on the tray <NUM>), the optical detector(s) transmit a signal to control unit <NUM> indicating contact between the tray <NUM> and basin <NUM>. In response to receiving a signal from the optical detector(s) indicating contact between the tray <NUM> and basin <NUM>, the control unit <NUM> activates the heating elements <NUM>, <NUM> to heat the conductive core elements <NUM>, <NUM>.

While the tray <NUM> has been depicted as including two conductive core elements <NUM>, <NUM>, other numbers of conductive core elements <NUM>, <NUM> can be used. In addition, while basin <NUM> has been depicted as having two heating elements <NUM>, <NUM>, other numbers of heating elements can be used.

While the tray has been depicted as having two handles <NUM>, <NUM>, the tray can alternatively include a single handle or three or more handles. In addition, while the handles <NUM>, <NUM> are depicted as being formed into the tray <NUM>, one or more handles can be coupled to a surface of the tray.

While the basin system <NUM> has been depicted as including both contrast text <NUM> and an effluent sensor <NUM>, in some implementations, the system <NUM> includes contrast text <NUM> and does not include an effluent sensor <NUM>. In some implementations, includes an effluent sensor <NUM> and does not include contrast text <NUM>.

In addition, while the effluent sensor has been described as being an optical sensor, in some implementations, the effluent sensor <NUM> is an ultrasonic sensor. An ultrasonic effluent sensor <NUM> can be used to detect the presence of one or more foreign substances in effluent, such fibrin or other particles in the effluent in the drain bag <NUM>. In response to detecting foreign substances in the effluent using an ultrasonic effluent sensor <NUM>, a signal indicating the presence of foreign substances in the effluent can be transmitted to the control unit <NUM>, which, in response, can cause the graphical display <NUM> and/or the speaker <NUM> of the basin <NUM> to generate an alarm indicating foreign substances in the effluent.

While the effluent sensor <NUM> has been described as being activated in response to user input, in some implementations, the effluent sensor <NUM> is automatically operated by the control unit <NUM> without requiring user input. For example, in response to receiving a signal from the weight scale <NUM> indicating that a predetermined amount of time has elapsed since any weight increases were detected by the scale <NUM>, indicating that the drain cycle is complete, the control unit <NUM> can activate the effluent sensor <NUM> to automatically scan the effluent contained in the drain bag <NUM> and transmit the results to the control unit <NUM>. In some implementations, the effluent sensor <NUM> is configured to periodically scan the effluent at predetermined intervals throughout the draining process (e.g., every <NUM> to <NUM> minutes during the draining process).

While the leak detector <NUM> has been depicted as being formed of two metal rings <NUM>, <NUM>, other types of leak detectors can be used for detecting fluids leaked into the basin <NUM>. For example, in some implementations, the leak detector includes two probes serving as positive and negative terminals. When electrically conductive fluid, such as dialysate or effluent, leaks into the chamber <NUM> and contacts the two probes of the leak detector <NUM>, the leaked fluid bridges the gap between the probes and allows electrical current to flow from positive to negative terminals to complete a circuit. In response to completion of the circuit formed by the leak detector <NUM>, the leak detector <NUM> transmits a signal to a computing device (e.g., control unit <NUM>) indicating the presence of a leak.

In some implementations, the basin <NUM> includes a leak detector <NUM> having a pair of ultrasonic heads positioned opposite each other (e.g., in a formed between the scale <NUM> and the bottom surface <NUM> of the chamber <NUM>), and when leaked fluid flows into the chamber and passes between the ultrasonic heads, the leak detector <NUM> transmits a signal to a computing device (e.g., control unit <NUM>) indicating the presence of a leak.

In some implementations, the system <NUM> includes a leak detector <NUM> having a rotameter with an optical sensor that detects fluid as it moves a float in a chamber of the leak detector <NUM>. In response to the optical sensor detecting that the float has moved within the chamber, the leak detector <NUM> transmits a signal to a computing device (e.g., control unit <NUM>) indicating the presence of a leak.

In some implementations, the leak detector <NUM> includes a microphone, and a leak into the basin <NUM> is detected based on the control unit <NUM> receiving sound recordings from the leak detector and detecting that the recordings include a noise generated by fluid flowing past the leak detector <NUM> of the leak detector <NUM>.

In some implementations, the leak detector <NUM> includes a turbine or wheel and when fluid leaked into the basin flows past the turbine or wheel of the leak detector <NUM>, it causes the wheel or turbine to rotate. In response to rotation of the wheel or turbine, the leak detector <NUM> transmits a signal to a computing device (e.g., control unit <NUM>) indicating the presence of a leak.

In some implementations, the leak detector <NUM> includes a piezoelectric sensor, and when fluid leaked into the basin <NUM> contacts the piezoelectric sensor of the leak detector <NUM> the leak detector <NUM> transmits a signal to a computing device (e.g., control unit <NUM>) indicating the presence of a leak.

In some implementations, the leak detector <NUM> includes an optical flow sensor that generates a laser beam, and as fluid leaked into the basin <NUM> flows past the leak detector, the laser beam is interrupted, which is detected by the optical flow sensor. In response to the optical flow sensor detecting interruption of the laser beam, the leak detector <NUM> transmits a signal to a computing device (e.g., control unit <NUM>) indicating the presence of a leak.

In some implementations, the leak detector <NUM> includes a thermal sensor that detects a change in temperature when fluid is leaked into basin <NUM>. For example, the thermal sensor can detect when leaked fluid reduces the temperature of a hot spot in the basin. In response to the thermal sensor detecting a change in temperature caused by leaked fluid, the leak detector <NUM> transmits a signal to a computing device (e.g., control unit <NUM>) indicating the presence of a leak.

While the stand <NUM> for hanging dialysate bags <NUM> during the fill phase of CAPD treatment has been depicted as being separate from the basin system <NUM>, in some implementations a stand for hanging dialysate bags is integrated into the basin <NUM> of the basin system <NUM>.

In addition, while the basin system <NUM> has been depicted as being placed on the floor next to the patient <NUM>, the basin system <NUM> can be positioned on other surfaces during treatment. For example, the basin system <NUM> can be positioned on a chair or table near the patient <NUM> during treatment in order to position the basin system <NUM> within reach of the patient <NUM>.

While the flow sensor <NUM> has been described as transmitting sensor data to the control unit <NUM> by interfacing with a port <NUM>, <NUM> on the basin <NUM>, in some implementations, the flow sensor <NUM> is wirelessly coupled to the control unit <NUM> of the basin <NUM> and transmits data to the control unit <NUM> wirelessly (e.g., using a Bluetooth or another near field communication connection). In some implementations, sensor data is transmitted from the flow sensor <NUM> to the control unit <NUM> in real time.

In addition, while the volume of fluid provided to the patient during a fill phase has been described as being measured using a flow sensor <NUM>, in some implementations the amount of fluid provided to the patient <NUM> during the fill phase of treatment is measured using a load cell coupled to the stand <NUM>. For example, at the beginning of the fill phase, the dialysate bag <NUM> can be hung from or otherwise attached to a load cell attached to stand <NUM>. As fluid flows from the dialysate bag <NUM> to the patient <NUM> during the fill phase of treatment and, as a result, the weight of the dialysate bag <NUM> decreases, these changes in weight can be measured by the load cell on stand <NUM>, and transmitted to the control unit <NUM>. Based on this decrease in weight measured by the load cell on stand <NUM>, the control unit <NUM> can determine a volume of dialysate provided to the patient during the fill phase of treatment.

Further, while the start time and end time of the fill phase have been described as being determined based on data received from the flow sensor <NUM>, other methods of determining a fill start time and a fill end time can be used. For example, as previously discussed, a dialysate bag <NUM> containing fresh dialysate can be placed on tray <NUM> for heating by the basin system <NUM> prior to beginning the fill phase. Once the heating is complete, the dialysate bag <NUM> is removed from the tray <NUM> and is attached to stand <NUM> to begin the fill phase. The weight scale <NUM> can detect the decrease in force applied to the tray <NUM> resulting from removal of the dialysate bag <NUM> from the tray <NUM> after completion of heating the dialysate, and in response to detecting the reduction in force at the end of heating, can send a signal to the control unit <NUM> indicating a start time of the fill phase corresponding to the time the reduction in force was detected. Similarly, after the fill phase is complete, the emptied (or partially emptied) dialysate bag <NUM> can be returned to the tray <NUM> for measurement of the final weight of the dialysate bag <NUM>. The weight scale <NUM> can detect an increase in force applied to the tray <NUM> resulting from the empty dialysate bag <NUM> being placed on the tray <NUM> at the end of the fill phase. In response to detecting the increase in force caused by placing the empty dialysate bag <NUM> on the tray <NUM> at the end of the fill phase, the weight scale <NUM> can send a signal to the control unit <NUM> indicating a end time of the fill phase corresponding to the time that the increase in force was detected due to placement of the empty dialysate bag <NUM> on the tray <NUM> at the end of the fill phase.

While user input has been described as being received by the control unit <NUM> through the graphical display <NUM> or microphone <NUM> of the basin <NUM>, in some implementations, a user can transmit data to the control unit <NUM> using a remote computing device, such as a mobile device. For example, in some implementations, a user can interface with an application on a mobile device to provide treatment data to the control unit <NUM> of the basin <NUM> and provide commands for controlling one or more components of the basin <NUM> to the control unit <NUM>. For example, the user can interface with an application on a computing device to provide data such as the dialysate concentration, the dialysate expiry date, dialysate volume exchanged during treatment, fill start time, fill end time, dwell time, drain start time, drain end time, the amount of fluid drained during the treatment, the clarity of effluent drained during the treatment.

In addition, while alarms, messages, and warning have been described as being provided to the user by the graphical display <NUM> and the speaker <NUM> of the basin <NUM>, in some implementations, the control unit <NUM> can additionally or alternatively transmit alarms, messages, and warning to one or more remote computing devices. For example, the control unit <NUM> can transmit alarms, messages, and warnings as push notifications on a user's mobile device. In some implementations, the control unit <NUM> transmits alarms, messages, and warnings to a user's computing device for display in an application operating on the user's computing device.

While the components of the basin <NUM> have been described as being powered by a rechargeable battery, other power sources may be used to provide power to the basin <NUM>. For example, the basin <NUM> may be powered by a power supply directly through connection of the power source to the power adapter <NUM> on the back of the basin <NUM> via a power cable.

While the control unit <NUM> has been described as transmitting treatment data to one or more remote computing devices for storage, in some implementations, the treatment data is additionally or alternatively stored on a local storage device of the basin system <NUM>.

While the basin system <NUM> has been described as supporting both a dialysate bag <NUM> and a drain bag <NUM> during PD treatment, the basin system <NUM> can alternatively be used for supporting only the dialysate bag <NUM> during treatment or supporting only the drain bag <NUM> during treatment.

While the basin system <NUM> has been described as being used as part of a PD system <NUM> during PD treatment, the basin system <NUM> can also be used during other blood treatments including, but not limited, hemodialysis (HD) treatment, hemofiltration (HF) treatment, and hemodiafiltration (HDF).

<FIG> depicts an example blood treatment system <NUM> for performing one or more types of blood treatments, including HD, HF, and HDF treatments. As can be seen in <FIG>, the blood treatment system <NUM> includes a blood treatment machine <NUM> to which a disposable blood component set <NUM> that forms a blood circuit is connected.

The blood treatment system <NUM> includes a fluid conditioning system <NUM> that is fluidly coupled to the blood treatment machine <NUM> and produces fluid to be used during the treatment, such as dialysate fluid, that can be provided to the blood treatment machine <NUM>.

The blood treatment system <NUM> also includes a waste line <NUM> that is connected at a first end to the fluid circuit of the blood treatment machine <NUM> and is connected at a second end to a drain bag <NUM>.

During treatment, arterial and venous patient lines of the disposable blood component set are connected to the patient and blood is circulated through various blood lines and components of the blood component set. At the same time, fresh dialysate is generated by the fluid conditioning system <NUM> and flows from the fluid conditioning system <NUM> to a dialyzer of the dialysis treatment machine via fluid lines. During treatment, toxins are removed from the patient's blood and collected in the dialysate flowed through the dialyzer. The filtered blood is then returned to the patient and the spent dialysate exiting the dialyzer is flowed back to the fluid conditioning system <NUM>. A sorbent cartridge <NUM> of the fluid conditioning system <NUM>, removes (e.g., filters out) toxic substances that have collected in the spent dialysate to produce "regenerated" dialysate (e.g., cleaned, unconditioned dialysate) that flows out of the sorbent cartridge <NUM>. The regenerated dialysate exiting the sorbent cartridge <NUM> is further conditioned by the fluid conditioning system <NUM> to meet acceptable physiological properties and is then pumped back to the blood treatment machine <NUM> as "fresh" dialysate.

Once treatment is complete, the spent dialysate (and any additional fluid removed from the patient) is drained from the fluid circuits of the blood treatment machine <NUM> and the fluid conditioning system <NUM> through the waste line <NUM> and into drain bag <NUM>. For example, one or more pumps of the blood treatment machine <NUM> and/or the fluid conditioning system <NUM> can be operated to draw fluid out of the fluid circuit(s) of the blood treatment machine <NUM> and/or the fluid conditioning system <NUM>, through waste line <NUM>, and into drain bag <NUM>.

As can be seen in <FIG>, the drain bag <NUM> of the blood treatment system <NUM> can be supported by a respective basin system <NUM> during the treatment. For example, the basin system <NUM> supporting the drain bag <NUM> can be used to measure a weight of fluid provided to the drain bag at the end of the treatment (e.g., by using weight scale <NUM> of basin system <NUM>). The basin system <NUM> can also be used to detect a clarity of the spent dialysate contained in the drain bag <NUM> (e.g., using contrast text <NUM> and/or effluent sensor <NUM>, as described above). The basin system <NUM> can also be used to detect if leakage from the drain bag <NUM> has occurred during treatment using a leak detector positioned in the basin <NUM> of the basin system <NUM> (e.g., leak detector <NUM>).

In addition, the basin system <NUM> can be used to record and automatically transmit data related to the blood treatment to a remote computing device. For example, the basin system supporting the drain bag <NUM> can record and transmit an amount of spent dialysate drained during treatment, any leakages from the drain bag <NUM> detected during treatment, a clarity of the spent dialysate in the drain bag <NUM>, and an end time for the treatment (e.g., the time corresponding to the last increase in weight of the drain bag <NUM> as detected by a weight scale of the basin system <NUM>, such as weight scale <NUM>). In some implementations, the treatment data is transmitted from the basin system <NUM> to one or more remote computing devices in real time. Recording and transmitting treatment data using the basin system <NUM> is described in detail above with reference to <FIG>.

While <FIG> depicts using a single basin system <NUM> to support a drain bag <NUM> during an HD, HF, or HDF treatment, in some implementations, a basin system can be used to support a container of dialysate fluid (or other fluid used by the fluid conditioning system <NUM> to generate dialysate) during treatment using the blood treatment machine <NUM>. In addition, basin systems <NUM> used to support dialysate bags can include a heating system (e.g., conductive core elements <NUM>, <NUM> and heating elements <NUM>, <NUM>) while the basin system used to support the drain bag <NUM> does not include a heating system.
