The above summary is provided merely for purposes of summarizing some example embodiments to provide a basic understanding of some aspects of the present disclosure. Accordingly, it will be appreciated that the above-described embodiments are merely examples and should not be construed to narrow the scope or spirit of the disclosure in any way. It will be appreciated that the scope of the present disclosure encompasses many potential embodiments in addition to those here summarized, some of which will be further described below.

Reference will now be made to the accompanying drawings. The components illustrated in the figures may or may not be present in certain embodiments described herein. Some embodiments may include fewer (or more) components than those shown in the figures in accordance with an example embodiment of the present disclosure.

Example embodiments will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of disclosure are shown. Indeed, embodiments of the disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements.

Example embodiments disclosed herein address technical problems associated with sensing and secretion bypass apparatuses for measuring air flow and associated methods. As would be understood by one skilled in the field to which this disclosure pertains, there are numerous example scenarios in which a user may use sensing and secretion bypass apparatuses for measuring air flow and associated methods.

In many applications, it is often necessary to measure the properties associated with an air flow. For example, in individuals who are undergoing mechanical ventilation it is necessary to measure the air flowing out of the individual's lungs (e.g., expiratory air flow) and/or the air flowing into an individual's lungs (e.g., inspiratory air flow) to monitor the individual's health and/or the effectiveness of the mechanical ventilation. For example, measuring the oxygen concentration of the air flowing out of the individual's lungs can be an indicator of the individual's health and/or the effectiveness of the mechanical ventilation.

Example solutions for measuring expiratory air flow and/or inspiratory air flow include, for example, placing an air flow sensor in series with a tube from which air is expelled from an individual's lungs in mechanical ventilation and/or a tube from which air is provided to an individual's lungs in mechanical ventilation (e.g., an expiratory tube and/or inspiratory tube proximal to the patient) and measuring the expiratory air flow and/or inspiratory air flow as it moves through the air flow sensor. However, in some examples, there may be secretions (e.g., condensed water vapor, mucus, fluid, and/or organic material present in an individual's respiratory and/or digestive system) present in the expiratory air flow and/or inspiratory air flow. The secretions present in the expiratory air flow and/or inspiratory air flow may cause the air flow sensor to clog (e.g., secretions, such as mucus, may stick to the air flow sensor), measurements taken by the air flow sensor to be inaccurate (e.g., secretions in the air flow may alter the properties of the air flow), and/or the air flow sensor to fail. This can harm the individual's health and trigger alarms causing medical staff to respond, disrupting the workflow of medical staff. In many implementations, the only way to ensure measurements taken by the air flow sensor are accurate and prevent the air flow sensor from clogging, is to perform frequent inspections and regular cleaning of the air flow sensor and/or regularly replace the air flow sensor with a new air flow sensor. However, regular inspection and cleaning of the air flow sensor and/or replacement of the air flow sensor results in less efficient utilization of resources (e.g., medical staff must spend time inspecting and cleaning and/or replacing the air flow sensor), may cause harm to an individual's health because it is often necessary to detach the air flow sensor from the expiratory tube and/or inspiratory tube in order to inspect and clean and/or replace the air flow sensor, and may expose medical staff to infections (e.g., the secretions may be a biohazard).

Thus, to address these and/or other issues related to measuring air flow, example systems, apparatuses, and/or methods for measuring air flow are disclosed herein. For example, an embodiment in this disclosure, described in greater detail below, includes an adapter with a chamber having a first end for receiving an air flow having secretions and a second end connected to an air flow sensor. An elevated member is disposed within the chamber proximate the second end that prevents the secretions from entering the air flow sensor. A disposal housing is in fluid communication with the chamber and configured to collect the secretions. As a result, in some examples, secretions are prevented from interfering with measurements made by the air flow sensor by at least the elevated member and the secretions can be collected and disposed of without interfering with the measurement of the air flow (e.g., the disposal housing may be removed for disposal of the secretions without halting the air flow measurements).

As another example, an embodiment in this disclosure, not part of the invention and described in greater detail below, includes an upper portion that may receive an air flow from an expiratory circuit and/or inspiratory circuit connected to the upper portion. In some examples, a lower portion may be removably attached to the upper portion. In some examples, a collection housing may be disposed on an inner surface of the lower portion and be configured to collect secretions in the air flow. In some examples, an air flow measurement apparatus may be configured to measure one or more properties associated with the air flow when the lower portion is detached from the upper portion. As a result, in some examples, the secretions are prevented from interfering with measurements made by the air flow sensor (e.g., the secretions collect in the collection housing) and the secretions can be collected and disposed of without interfering with the measurement of the air flow (e.g., the lower portion may be detached from the upper portion to dispose of the secretions while the air flow measurement apparatus continues to measure the one or more properties associated with the air flow).

With reference to <FIG> and <FIG>, embodiments herein provide for an example sensing and secretion bypass apparatus <NUM>. The sensing and secretion bypass apparatus <NUM> is configured to measure an air flow and bypass secretions present in the air flow.

The sensing and secretion bypass apparatus <NUM> includes an air flow sensor <NUM>. The air flow sensor <NUM> may include an air flow sensor chamber <NUM>. The air flow sensor <NUM> may include an air flow measurement apparatus <NUM> disposed within the air flow sensor chamber <NUM>. The air flow measurement apparatus <NUM> may be configured to measure one or more properties associated with the air flow. The one or more properties associated with the air flow may include one or more of a velocity, a pressure, a humidity, a temperature, an oxygen concentration or a presence of oxygen, a carbon dioxide concentration or a presence of carbon dioxide, a nitric oxide concentration or a presence of nitric oxide, a methane concentration or a presence of methane, a volatile organic compound concentration (e.g., benzene, ethylene glycol, formaldehyde, acetone, methylene chloride, tetrachloroethylene, toluene, xylene, and/or <NUM>,<NUM>-butadiene) or a presence of a volatile organic compound, a mass, and a volume associated with the air flow. The air flow measurement apparatus <NUM> may be one or more of a hot-wire anemometer, thermopile, and/or differential pressure sensor or transducer.

Although the air flow sensor <NUM> depicted in <FIG> and <FIG> includes a single air flow measurement apparatus <NUM>, it would be understood by one skilled in the field to which this disclosure pertains that, in some embodiments, the air flow sensor <NUM> may include more than one air flow measurement apparatus <NUM>. For example, the air flow sensor <NUM> may include multiple air flow measurement apparatuses <NUM> with each air flow measurement apparatus <NUM> configured to measure a particular property associated with the air flow (e.g., an air flow measurement apparatus <NUM> for measuring the velocity of the air flow, an air flow measurement apparatus <NUM> for measuring the humidity of the air flow, etc.).

In some embodiments, the air flow sensor <NUM> may include a controller <NUM>. The controller <NUM> may be configured to receive one or more measurements made by the air flow measurement apparatus <NUM> from the air flow measurement apparatus <NUM>. For example, the controller <NUM> may receive a velocity of the air flow. The controller <NUM> may receive the one or more measurements made by the air flow measurement apparatus <NUM> via a wired connection and/or a wireless connection (e.g., Bluetooth). In some embodiments, the controller <NUM> may be disposed on an outer surface of the air flow sensor <NUM>. In other embodiments, the controller <NUM> may be disposed inside the air flow sensor chamber <NUM>. Although the controller <NUM> and the air flow measurement apparatus <NUM> are depicted as separate components in <FIG> and <FIG>, it would be understood by one skilled in the field to which this disclosure pertains that, in some embodiments, the controller <NUM> and the air flow measurement apparatus <NUM> may be combined into a single component.

In some embodiments, the air flow sensor <NUM> may be comprised of any suitable material for facilitating the measurement of an air flow. In this regard, the air flow sensor <NUM> may comprise one or more of plastic, silicone, and/or metal (e.g., gold, copper, etc.). For example, if the air flow measurement apparatus <NUM> is a thermopile, the air flow sensor <NUM> may comprise plastic and/or metal (e.g., copper). As another example, if the air flow measurement apparatus <NUM> is a differential pressure sensor, the air flow sensor <NUM> may comprise plastic. In some embodiments, the air flow sensor <NUM> may be any suitable shape for facilitating the measurement of an air flow. For example, the air flow sensor <NUM> may be one or more of cylindrical, spherical, circular, rectangular, or cubical.

The sensing and secretion bypass apparatus <NUM> includes an adapter <NUM>. The adapter <NUM> includes an adapter chamber <NUM>. The adapter chamber <NUM> includes a first end <NUM> and a second end <NUM>. The first end <NUM> of the adapter chamber <NUM> is configured to receive the air flow. In some embodiments, secretions may be present in the air flow. The secretions may include, for example, condensed water vapor, mucus, fluid, and/or organic material present in an individual's respiratory and/or digestive system. The second end <NUM> of the adapter chamber <NUM> may be connected to the air flow sensor <NUM>.

An elevated member <NUM> is disposed within the adapter chamber <NUM>. The elevated member <NUM> is disposed proximate the second end <NUM> of the adapter chamber <NUM>. In this regard, the elevated member <NUM> includes a first end <NUM> and a second end <NUM>. The first end <NUM> of the elevated member <NUM> is in contact with a bottom side <NUM> of the adapter chamber <NUM>. The second end <NUM> of the adapter chamber <NUM> is separated from the bottom side <NUM> of the adapter chamber <NUM> by a first distance d<NUM>.

The first distance d<NUM> is less than a height h<NUM> of the adapter chamber <NUM>. As a result, there may be a second distance d<NUM> between the second end <NUM> of the elevated member <NUM> and a top side <NUM> of the adapter chamber <NUM> (e.g., d<NUM> plus d<NUM> are equal to hi). Said differently, the elevated member <NUM> is disposed within the adapter chamber <NUM> such that the elevated member <NUM> is proximate the second end <NUM> of the adapter chamber <NUM> and the elevated member <NUM> has a downward slope from the second end <NUM> of the adapter chamber <NUM> towards the first end <NUM> of the adapter chamber <NUM>.

In some embodiments, after the air flow is received via the first end <NUM> of the adapter chamber <NUM>, the air flow may flow through the adapter chamber <NUM> in direction x towards the second end <NUM> of the adapter chamber <NUM>. As the air flow travels through the adapter chamber <NUM>, the secretions present in the air flow may slowly begin to sink towards the bottom side <NUM> of the adapter chamber <NUM> due to the force of gravity. As a result, as the air flow moves through the adapter chamber <NUM>, at least some of the secretions eventually impact the elevated member <NUM> (e.g., some of the secretions may sink to the bottom side <NUM> of the adapter chamber <NUM> due to the force of gravity before reaching the elevated member <NUM>). After secretions impact the elevated member <NUM>, the air flow (e.g., without the secretions) may continue to the second end <NUM> of the adapter chamber <NUM> and flow into the air flow sensor <NUM> (e.g., through the space defined by the second distance d<NUM> between the second end <NUM> of the elevated member <NUM> and a top side <NUM> of the adapter chamber <NUM>). Accordingly, the elevated member <NUM> is configured to prevent secretions present in the air flow from entering the air flow sensor <NUM> while still enabling the air flow without the secretions to flow from the adapter chamber <NUM> into the air flow sensor <NUM> via the second end <NUM> of the adapter chamber <NUM>.

In some embodiments, the adapter <NUM> may comprise any suitable material for receiving the air flow and being connected to the air flow sensor <NUM>. Similarly, the elevated member <NUM> may be any suitable material for preventing secretions present in the air flow from entering the air flow sensor <NUM> while still enabling the air flow without the secretions to flow from the adapter chamber <NUM> into the air flow sensor <NUM> via the second end <NUM> of the adapter chamber <NUM>. For example, the adapter <NUM> and/or the elevated member <NUM> may comprise one or more of plastic, silicone, and/or metal (e.g., gold, copper, etc.). In some embodiments, the adapter <NUM> may be any suitable shape for receiving the air flow and being connected to the air flow sensor <NUM>. For example, the adapter <NUM> may be one or more of cylindrical, spherical, circular, rectangular, or cubical.

Although the adapter <NUM> and the air flow sensor <NUM> are depicted as separate components in <FIG> and <FIG>, it would be understood by one skilled in the field to which this disclosure pertains that, in some embodiments, the adapter <NUM> and the air flow sensor <NUM> may be combined into a single component.

The sensing and secretion bypass apparatus <NUM> includes a disposal housing <NUM>. The disposal housing <NUM> is in fluid communication with the adapter chamber <NUM> of the adapter <NUM>. For example, the disposal housing <NUM> is in fluid communication with the adapter chamber <NUM> via a tube <NUM>. The disposal housing <NUM> is configured to collect secretions received from the adapter chamber <NUM>. In this regard, as secretions sink to the bottom side <NUM> of the adapter chamber <NUM> and may fall into the disposal housing <NUM> via the tube <NUM> and be collected in the disposal housing <NUM>. Additionally or alternatively, after secretions impact the elevated member <NUM> disposed in the adapter chamber <NUM>, the secretions may begin to slide down the elevated member <NUM> due to the force of gravity (e.g., because the elevated member <NUM> is sloped). Accordingly, secretions that impact the elevated member <NUM> may eventually reach the first end <NUM> of the elevated member <NUM> and, at this point, may fall into the disposal housing <NUM> via the tube <NUM> and be collected in the disposal housing <NUM>.

In some embodiments, after a certain quantity of secretions have collected in the disposal housing <NUM>, the disposal housing <NUM> may be detached from the adapter chamber <NUM> to dispose of the secretions. The disposal housing <NUM> may be detached from the adapter chamber <NUM> while the air flow measurement apparatus <NUM> is measuring the air flow, thus, the secretions may be disposed of without interfering with the measurements made by the air flow measurement apparatus <NUM>.

In some embodiments, the disposal housing <NUM> may comprise any suitable material for collecting the secretions from the adapter chamber <NUM>. For example, the disposal housing <NUM> may comprise one or more of plastic, silicone, and/or metal (e.g., gold, copper, etc.). In some embodiments, the disposal housing <NUM> may be any suitable shape for collecting the secretions from the adapter chamber <NUM>. For example, the disposal housing <NUM> may be one or more of cylindrical, spherical, circular, rectangular, or cubical.

In some embodiments, the adapter chamber <NUM> of the adapter <NUM> may be configured to receive the air flow from an expiratory circuit or inspiratory circuit <NUM> via the first end <NUM> of the adapter chamber <NUM>. In some embodiments, the expiratory circuit or inspiratory circuit <NUM> may be associated with a mechanical ventilation device <NUM>. For example, the expiratory circuit or inspiratory circuit <NUM> may be configured to receive expiratory air flow or inspiratory air flow associated with the mechanical ventilation device <NUM>.

In some embodiments, the controller <NUM> may be in communication with the mechanical ventilation device <NUM>, such as via a wired connection and/or a wireless connection (e.g., Bluetooth). The controller <NUM> may be configured to transmit one or more measurements made by the air flow measurement apparatus <NUM> to the mechanical ventilation device <NUM> (e.g., the one or more properties associated with the air flow measured by the air flow measurement apparatus <NUM>). Similarly, the mechanical ventilation device <NUM> may be configured to receive the one or more measurements made by the air flow measurement apparatus <NUM>. Although the controller <NUM> and the mechanical ventilation device <NUM> are depicted as separate components in <FIG>, it would be understood by one skilled in the field to which this disclosure pertains that, in some embodiments, the controller <NUM> and the mechanical ventilation device <NUM> may be a single component. For example, in some embodiments, the controller <NUM> may be embodied within the mechanical ventilation device <NUM>.

In some embodiments, the mechanical ventilation device <NUM> may be configured to perform further analysis on the one or more measurements made by the air flow measurement apparatus <NUM> to determine one or more properties associated with the air flow. For example, the air flow measurement apparatus <NUM> (e.g., a hot-wire anemometer) may measure a temperature (e.g., a temperature change) and the mechanical ventilation device <NUM> may determine a velocity associated with the air flow based on the measured temperature.

With reference to <FIG>, in some embodiments, the mechanical ventilation device <NUM> may include a user interface <NUM>. In some embodiments, the user interface <NUM> may include a measured air flow component <NUM>. The measured air flow component <NUM> may be configured to display one or more measurements made by the air flow measurement apparatus <NUM> (e.g., the one or more measurements transmitted from the controller <NUM> and received by the mechanical ventilation device <NUM>) and/or one or more properties associated with the air flow determined by the mechanical ventilation device <NUM> performing further analysis on the one or more measurements made by the air flow measurement apparatus <NUM>. For example, the measured air flow component <NUM> may be configured to display the one or more properties associated with the air flow measured by the air flow measurement apparatus <NUM>, including one or more of a velocity, a pressure, a humidity, a temperature, an oxygen concentration or a presence of oxygen, a carbon dioxide concentration or a presence of carbon dioxide, a nitric oxide concentration or a presence of nitric oxide, a methane concentration or a presence of methane, a volatile organic compound concentration (e.g., benzene, ethylene glycol, formaldehyde, acetone, methylene chloride, tetrachloroethylene, toluene, xylene, and/or <NUM>,<NUM>-butadiene) or a presence of a volatile organic compound, a mass, and a volume associated with the air flow. In this regard, for example, the measured air flow component <NUM> may display text, symbols, graphs, and/or colors indicating one or more measurements made by the air flow measurement apparatus <NUM>. For example, the measured air flow component <NUM> may display text indicating the velocity of the air flow.

Although described herein with respect to the mechanical ventilation device <NUM> having a user interface <NUM> with a measured air flow component <NUM> configured to display one or more measurements made by the air flow measurement apparatus <NUM>, it would be understood by one skilled in the field to which this disclosure pertains that, in some embodiments, the controller <NUM> may include a user interface having a measured air flow component configured to display one or more measurements made by the air flow measurement apparatus <NUM>.

Referring now to <FIG>, a flowchart providing an example method <NUM> of manufacturing a sensing and secretion bypass apparatus is illustrated.

As shown in block <NUM>, the method of manufacturing includes providing an air flow sensor. As described above, the air flow sensor may include an air flow sensor chamber. An air flow measurement apparatus may be disposed within the air flow sensor chamber. The air flow measurement apparatus may be configured to measure one or more properties associated with the air flow. The one or more properties associated with the air flow may include one or more of a velocity, a pressure, a humidity, a temperature, an oxygen concentration or a presence of oxygen, a carbon dioxide concentration or a presence of carbon dioxide, a nitric oxide concentration or a presence of nitric oxide, a methane concentration or a presence of methane, a volatile organic compound concentration (e.g., benzene, ethylene glycol, formaldehyde, acetone, methylene chloride, tetrachloroethylene, toluene, xylene, and/or <NUM>,<NUM>-butadiene) or a presence of a volatile organic compound, a mass, and a volume associated with the air flow. As described above, the air flow measurement apparatus may be one or more of a hot-wire anemometer, thermopile, and/or differential pressure sensor or transducer.

As described above, the air flow sensor may include a controller. The controller may be configured to receive one or more measurements made by the air flow measurement apparatus from the air flow measurement apparatus. The controller may be in communication with a mechanical ventilation device, such as via a wired connection and/or a wireless connection (e.g., Bluetooth). The controller may be configured to transmit one or more measurements made by the air flow measurement apparatus to the mechanical ventilation device (e.g., the one or more properties associated with the air flow measured by the air flow measurement apparatus). Similarly, the mechanical ventilation device may be configured to receive the one or more measurements made by the air flow measurement apparatus. Although the controller and the mechanical ventilation device are depicted as separate components in <FIG>, it would be understood by one skilled in the field to which this disclosure pertains that, in some embodiments, the controller and the mechanical ventilation device may be a single component. For example, in some embodiments, the controller may be embodied within the mechanical ventilation device.

As described above, in some embodiments, the mechanical ventilation device may include a user interface. In some embodiments, the user interface may include a measured air flow component. The measured air flow component may be configured to display one or more measurements made by the air flow measurement apparatus (e.g., the one or more measurements transmitted from the controller and received by the mechanical ventilation device). Additionally, as described above, although described herein with respect to the mechanical ventilation device having a user interface with a measured air flow component configured to display one or more measurements made by the air flow measurement apparatus, it would be understood by one skilled in the field to which this disclosure pertains that, in some embodiments, the controller may include a user interface having a measured air flow component configured to display one or more measurements made by the air flow measurement apparatus.

As shown in block <NUM>, the method of manufacturing includes providing an adapter comprising an adapter chamber having a first end configured to receive an air flow and a second end connected to the air flow sensor. As described above the air flow includes secretions.

As shown in block <NUM>, the method of manufacturing includes providing an elevated member disposed within the chamber proximate the second end and configured to prevent the secretions from entering the air flow sensor. As described above, after the air flow is received via the first end of the adapter chamber, the air flow may flow through the adapter chamber in direction x towards the second end of the adapter chamber. As the air flow travels through the adapter chamber, the secretions present in the air flow may slowly begin to sink towards the bottom side of the adapter chamber due to the force of gravity. As a result, as the air flow moves through the adapter chamber, at least some of the secretions eventually impact the elevated member (e.g., some of the secretions may sink to the bottom side of the adapter chamber due to the force of gravity before reaching the elevated member). After the secretions impact the elevated member, the air flow (e.g., without the secretions) may continue to the second end of the adapter chamber and flow into the air flow sensor (e.g., through the space defined by the second distance d<NUM> between the second end of the elevated member and a top side of the adapter chamber). Accordingly, the elevated member is configured to prevent secretions present in the air flow from entering the air flow sensor while still enabling the air flow without the secretions to flow from the adapter chamber into the air flow sensor via the second end of the adapter chamber.

As shown in block <NUM>, the method of manufacturing includes providing a disposal housing in fluid communication with the chamber of the adapter and configured to collect the secretions received via the first end of the chamber. As described above, the disposal housing is in fluid communication with the adapter chamber of the adapter. For example, the disposal housing is in fluid communication with the adapter chamber via a tube. The disposal housing is configured to collect secretions received from the adapter chamber. In this regard, as secretions sink to the bottom side of the adapter chamber and may fall into the disposal housing via the tube and be collected in the disposal housing. Additionally or alternatively, after secretions impact the elevated member disposed in the adapter chamber, the secretions may begin to slide down the elevated member due to the force of gravity (e.g., because the elevated member is sloped). Accordingly, secretions that impact the elevated member may eventually reach the first end of the elevated member and, at this point, may fall into the disposal housing via the tube and be collected in the disposal housing.

With reference to <FIG> and <FIG>, embodiments herein, which are not part of the invention, provide for an example sensing and secretion bypass apparatus <NUM>. In some embodiments, the sensing and secretion bypass apparatus <NUM> may be configured to measure an air flow and bypass secretions present in the air flow.

In some embodiments, the sensing and secretion bypass apparatus <NUM> may include an upper portion <NUM>. The upper portion <NUM> may be connected to an expiratory circuit or inspiratory circuit <NUM>. The upper portion <NUM> may receive an air flow from the expiratory circuit or inspiratory circuit <NUM>. The expiratory circuit or inspiratory circuit <NUM> may be associated with a mechanical ventilation device <NUM>. For example, the expiratory circuit or inspiratory circuit <NUM> may be configured to receive expiratory air flow or inspiratory air flow associated with the mechanical ventilation device <NUM>.

In some embodiments, there may be secretions present in the air flow.
