Title: Remote maintenance of medical devices

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application is a continuation of U.S. application Ser. No. 14/256,663 filed on Apr. 18, 2014, entitled “Remote Maintenance of Medical Devices,” the disclosure of which is incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     The subject matter described herein relates to a modular medical device system having one or more medical device modules and, more particularly, to the remote testing of the medical device modules. 
     BACKGROUND 
     Medical device systems may utilize a plurality of different medical devices that are distinct stand-alone or independent medical devices. For example, some conventional infusion pumping systems may include up to about four functionally distinct stand-alone infusion pumps. Conventional infusion pumps are typically stand-alone complex devices that are only able to provide independent complex infusion functions. As such, coordination or control of the devices collectively is complex and difficult. 
     This difficulty extends to the powering of each stand-alone device. A device requires a sufficient amount of power in order to operate properly. Whether the amount of received power is adequate can depend on many factors including, for example, the power supply, the stand-alone device, and the link between the power supply and the stand-alone device. In order to ensure that each component is operating properly, these components may be subject to regular inspection and testing. 
     SUMMARY 
     In some implementations, methods and apparatus, including computer program products, and systems are provided for conducting maintenance tests on a medical device across a network from a remote location using a remote maintenance application. 
     In one aspect, a request to conduct at least one test on a medical device module remotely located from a party initiating the request is received by at least one processor. The medical device module includes an inductive receiver and is part of a medical device system. The medical device system includes an inductive backplane having a plurality of mounting seats. Each mounting seat has an inductive transmitter. The inductive backplane is configured to inductively power the medical device module when the medical device module is affixed to a first mounting seat. The at least one test relates to at least one attribute of the inductive transmitter of the first mounting seat or the inductive receiver of the medical device module. The request identifies the medical device module to be tested and the at least one test to be conducted. A message representative of the request is transmitted to the medical device system by the at least one processor. Test data based on the one or more tests is received by the at least one processor. The test data relates to the at least one attribute of the inductive transmitter of the first mounting seat or the at least one attribute of the inductive receiver of the medical device module. The test data is provided by the at least one processor. 
     The above methods, apparatus, computer program products, and systems can, in some implementations, further include one or more of the following features. 
     The test data can be provided by performing at least one of transmitting the test data, loading the test data, storing the test data, and displaying the test data. 
     An indication that the medical device module is not currently being used to treat a patient can be received by the at least one processor before the message is transmitted. 
     The at least one attribute of the inductive transmitter of the first mounting seat and the inductive receiver of the medical device module can include at least a link efficiency, an input voltage, an input current, an output power, and a temperature. 
     Authentication information can be received by the at least one processor from the party initiating the request. The authentication information can include at least a role of the party. The identity of the party can be authenticated by the at least one processor before the message is transmitted. The contents of the provided test data can be based on the role of the party initiating the request. 
     The message can indicate that the at least one test is automatically conducted by the medical device system or requires user intervention. 
     A second request can be received by the at least one processor to conduct additional tests on the medical device module in the first mounting seat after the test data is provided. A message representative of the second request can be transmitted by the at least one processor to the medical device system. 
     The medical device module can be an infusion pump selected from a group consisting of syringe pumps, patient controlled infusion pumps, large volume infusion pumps, and peristaltic pumps. 
     Computer program products are also described that comprise non-transitory computer readable media storing instructions, which when executed one or more data processor of one or more computing systems, causes at least one data processor to perform operations herein. Similarly, computer systems are also described that may include one or more data processors and a memory coupled to the one or more data processors. The memory may temporarily or permanently store instructions that cause at least one processor to perform one or more of the operations described herein. In addition, methods can be implemented by one or more data processors either within a single computing system or distributed among two or more computing systems. Such computing systems can be connected and can exchange data and/or commands or other instructions or the like via one or more connections, including but not limited to a connection over a network (e.g. the Internet, a wireless wide area network, a local area network, a wide area network, a wired network, or the like), via a direct connection between one or more of the multiple computing systems, etc. 
     The subject matter described herein provides many advantages. For example, the current subject matter allows a user to remotely conduct maintenance tests on a medical device across a network. A user can utilize a remote maintenance application to specify the tests to be conducted, receive the corresponding test data, and analyze the test data. 
     The details of one or more variations of the subject matter described herein are set forth in the accompanying drawings and the description below. Other features and advantages of the subject matter described herein will be apparent from the description and drawings, and from the claims.

     DETAILED DESCRIPTION 
       FIG. 1  is a diagram  100  illustrating a modular medical device system  110 . The system  110  comprises a backplane  120  that can be mounted on a pole  105 . The backplane  120  can mechanically couple to and secure one or more medical device modules  150  along each of a series of pre-defined mounting seats  112 . In some variations, each of the mounting seats  112  are uniform in size and spacing, while in other variations different sizing and/or spacing can be used to accommodate medical device modules  150  having different exterior dimensions. In addition, the mounting seats  112  can be arranged along a single axis (e.g., a vertical axis as illustrated, etc.) or they can be arranged along two or more axes. The mounting seats  112  can each have one or more mechanical elements to detachably affix the medical device modules  150  to the backplane  120 . 
     In addition to allowing the medical device modules to be affixed to the system, the backplane  120  can provide non-contact inductive power to one or more medical device modules  150 . The backplane  120  can, for each mounting location, comprise an inductive transmitter  122  for non-contact powering of a medical device module  150 . A corresponding inductive receiver  152  on the medical device module  150  can, when the medical device module  150  is affixed to the mounting seat  112 , be inductively coupled with inductive transmitter  122  of backplane  120 . In general, energy is sent via an inductive (magnetic) coupling between inductive transmitter  122  and inductive receiver  152 . As a result, there is a wireless (no galvanic contact) energy transfer between inductive backplane  120  and medical device module  150 . Moreover, an electrical galvanic connector, as is typical for powering conventional medical devices, is not required to provide power to medical device module  150 . Use of non-contacting energy transfer avoids metallic contacts between medical device module  150  and a power source which may be damaged, require special cleaning and pose risk of electrical heating, smoke or fire. Each inductive transmitter  122  can be coupled to an induction bus  123  which in turn is connected to a power source  160  (e.g., a wired connection to an outlet, a battery, etc.) to enable the inductive coupling of each inductive transmitter  122 . 
     The backplane  120  can also provide an optical communications interface to one or more medical device modules  150  via respective optical communications ports  124  and optical transceivers  126  corresponding to each mounting seat  112 . The medical device modules  150  can have corresponding optical communications ports  154  and optical transceiver  156  which can be optically aligned with the optical communication port  124  on the backplane  120  when the medical device module  150  is affixed to the backplane  120  so that a bi-directional data feed can be established between the optical transceivers  126 ,  156 . Such data can relate to a variety of aspects including, but not limited to, data characterizing operation of the medical device module  150 , data for controlling (e.g., modifying, monitoring, etc.) one more attributes of the medical device module  150  (e.g., software updates, configuration updates, asset locations, status information, historical data, patient information, patient treatment parameters, medication administration information, etc.), and the like. Stated differently, the data exchanged via the optical transceivers  126 ,  156  can comprise any data generated or otherwise used by a medical device module  150  or a caregiver using same. The data transmitted to the backplane  120  can be consumed locally by the system  110  and/or it can be transmitted to one or more remote systems/devices coupled to the system  110  via a wired or wireless communications link. The optical data transceivers  126 ,  156  can be infrared (IR) data transceivers such that optical data  146  is propagated by IR light as the transmission medium. The optical data transceivers can be coupled to a communications bus  125  that in turn is coupled to a communications interface  142 . The communications interface  142  can, in turn, be coupled to the control unit  140 . In addition or in the alternative, a second communications interface  144  can provide an outward interface for the modular medical device system  110  that provides a wired or wireless connection to other devices and/or networks. It will be appreciated that any number of communications interfaces can be used, including one communications interface for each optical data transceiver  126 /seat  112 . 
     The control unit  140  can be hardware, software, or a combination of both. For example, the control unit  140  can be a specially designed hardware module including at least one data and memory with specialized software used to control any aspect of a medical device module  150  coupled to the system  110 . In other cases, the control unit  140  can be a software module (or series of modules) used to control any aspect of a medical device module  150  coupled to the system  110 . As used herein, unless otherwise specified, the term control shall relate to any type of data exchange with a medical device module  150  by the control unit  140  including data generated by a medical device module  150  and data used by a medical device module  150  (software updates, power state changes, etc.). For example, the control unit  140  can be used to selectively wake up medical device modules  150  coupled to the inductive backplane  120  from a sleep state. Furthermore, the control unit  140  can be coupled to one or more remote computing systems (via the communications interface  144 ) to allow for the remote control of the medical device modules  150 . 
     Each mounting seat  112  can include a shelf with dove tail features extending from a housing of the system  110 . Each medical device module  150  can include a latch mechanism on a top rear edge that affixes to the housing of the system  110 . The latch mechanism can reduce load on the shelf and can cause the medical device module  150  to rotate back into contact with the system  110  under load (rather than deflect away from it). This arrangement can help insure that the inductive transmitter  122  is positioned properly and secured in relation to the inductive receiver  152 . 
     Each mounting seat  112  can include a proximity sensor  127  that can detect the presence of a medical device module  150 . The proximity sensors  127  can be optical, electric, electro-mechanical, and/or mechanical devices. For example, the proximity sensors  127  can comprise a Hall effect sensor, an optical proximity sensor, and/or a mechanical switch. The presence of a medical device module  150  can be used to initiate, for example, inductive powering by the corresponding inductive transmitter  122  and/or communications via the communications interface  142 . The proximity sensor  127  can also indicate an alarm condition when a medical device module  150  is not completely secured so that appropriate actions can be taken. 
     Medical device module  150  can be any medical device that is compatible for scalability in a modular medical device system. For instance, the modular medical device system  110  can utilize one or more medical device modules  150  depending on the functionality that is needed for proper care of a patient. Moreover, a modular medical device system  110  can be scaled up to incorporate additional medical device modules  150  and also scaled down by removing medical device modules  150 . 
     For example, if patient care requires only one infusion pump, then the modular medical device system  110  can include a single affixed infusion pump. Moreover, if patient care requires two infusion pumps, then the modular medical device system  110  can be scaled up to include an affixed additional infusion pump. 
     Medical device modules  150  can include, but is not limited to, an infusion pump (e.g., a large volume pump (LVP), a syringe pump), a peristaltic pump, a patient-controlled analgesia (PCA) system, a vital signs monitor (VSM) (e.g., an SpO2 sensor, an EtCO2 sensors, cardiac output monitors, gastric tonometers, etc.), a bedside blood analyte analyzer (e.g. blood glucose), an Auto-ID module (barcode scanner and RFID), and other devices which measure physiological parameters associated with a patient and/or assist with the clinical care of the patient (and such medical device modules  150  may not necessarily measure physiological parameters of the patient). 
     Modular medical device system  110  can also comprise a display unit  130  that provides a unified interface that characterizes the operation of various medical device modules  150  coupled to the backplane  120 . The display unit  130  can comprise a touch screen interface that allows a user to selectively view and alter performance parameters/metrics of individual medical device modules  150 , concurrently view performance parameters/metrics of multiple medical device modules  150 , and additionally orchestrate complex sequences of infusions/operations from multiple medical device modules  150 . The display unit  130  can be affixed to an outer housing of the modular medical device system  130 /inductive backplane  120  by a tilt and swivel arm mount that allows the display unit to be moved on different sides of the system  110  and/or to change varying positions (to accommodate different positions/heights of caregivers). 
     The display unit  130  can include a speaker to provide audio cues relating to various aspects of medical device modules  150  (in other versions the speaker is located elsewhere in the system  110 ). When the medical device modules  150  are coupled to the backplane  120 , audio cues such as alarms for such medical device modules  150  can be delegated so that the system  110  handles the alarms whether via an audio and/or visual cue in the display unit  130  or by an audio cue generated elsewhere in the system  110 . In some cases, some alarms can be still be handled by a medical device module  150  while other alarms are handled by the system  110 . 
       FIG. 2  is a diagram  200  illustrating a modular medical device system  110  in a clinical setting. In particular, in this view, the modular medical device system  110  is coupled to two infusion pumps  150 A,  150 B, a vital signs monitor  150 C, and a syringe pump  150 D. The infusion pumps  150 A and  150 B are respectively fluidically coupled to two fluid/medication containers  222 ,  224  suspended from an IV pole  220 . In addition, each of the infusion pumps  150 A and  150 B and the syringe pump  150 D are fluidically coupled to an IV catheter inserted into a patient  210  so that the corresponding fluids can be delivered to the patient. The modular medical device system  110  monitors and/or controls how fluids from the respective sources  150 A,  150 B,  150 D are delivered to the patient  210 . It will be appreciated that varying numbers of medical device modules  150  can be utilized depending on the particular condition of and/or treatment the patient  210 . 
       FIG. 3  is a logic diagram  300  of a medical device module  150 . With  FIG. 3 , each medical device module  150  can include a secondary power source  156  such as a battery or a wired connection to an external power source. For example, the secondary power source  156  can power medical device module  150  when inductive receiver  152  is unable to power medical device module  150 . In one scenario, medical device module  150  is an infusion pump that is associated with (and fluidly communicating with) a patient. If the patient is moved to another location (e.g., to an x-ray room which is away from inductive backplane  110 ), then medical device module  150  must also move with the patient away from inductive backplane  120  in order to continue the current infusion without interruption. Upon a certain distance from inductive backplane  120 , inductive receiver  152  cannot be energized by inductive backplane  120  and therefore cannot power medical device module  150 . In other cases, the inductive backplane  120  may be turned off or operating in a mode not allowing the inductive receiver  152  to be energized. Accordingly, power source  156  (which may also be charged through inductive receiver  152 ) is able to provide the requisite power for medical device module  150 . In one variation, the power source  156  is a battery that can keep medical device module  150  operational in a range of about two to four hours. 
     Each medical device module  150  can also include memory  157  and at least one data processor  158 . The memory  157  can store instructions for execution by the at least one data processor  158  for use, for example, in the operation of the medical device module in a clinical setting. The memory  157  can also store data relating to the operation of the medical device module such as data characterizing how the medical device module  150  is used and parameters relating to same (e.g., number of hours operated, thresholds for alerts, etc.), performance and status information, and well as other aspects relating to the use of such medical device module  150  such as patient data, medication administration data, patient treatment parameters, etc. It is noted that when a medical device module  150  is reattached to the prior inductive backplane or a different inductive backplane, information required to continue the infusion stored in memory  157 , without interruption, can be transmitted from the medical device module  150  to the backplane (and to the control unit  140 ). 
     Each medical device module  150  can also comprise an additional communications interface  159  other than the optical data transceiver  154 . In some implementations the optical data transceiver  154  may not form part of the medical device module  150 . In these implementations, the communications interface  159  may be the only gateway for communication outside of the medical device module  150 ). This communications interface  159  can be fixed and/or wireless and be used to communicate to computer networks and peer-to-peer pairing with other devices when the medical device module  150  is not coupled to the backplane  120 . 
     In some implementations, the communications interface  159  can be used in addition or instead of the optical data transceiver  154  when the medical device module  150  is coupled to the backplane  120 . For example, the medical device module  150  can be seated on the backplane  120  but not have an optical data transceiver. In such a scenario, the communications interface  159  can wirelessly communicate with the control unit  140  of the modular medical device system  110  so that the operation of the medical device module  150  can be monitored and/or controlled by the modular medical device system  110  (whether or not the medical device module  150  is seated). Various types of wireless communications can be used (for this and other aspects described herein) such as short distance protocols such as BLUETOOTH, near field communication (NFC), WiFi, ZIGBEE, and the like. 
     As noted above, the system  110  comprises a control unit  140  (which in turn can comprise at least one data processor and memory for storing instructions for execution by the at least one data processor and/or data characterizing or otherwise relating to the operation of medication device modules  150 ). The control unit  140  can act to individually monitor and/or control the operation of the medical device modules  150  affixed to the backplane  120  such that the functionality of the medical device modules  150 , alone and/or in combination are increased. In some cases, the control unit  140  can orchestrate the operation of multiple medical device modules  150 . For example, certain sequences of operation and/or concurrent operation can be defined amongst the medical device modules  150 . Such an arrangement can permit, for example, coordinated infusion from different fluid sources. Some medical device modules  150  can have the ability to function fully independent of the control unit  140  for the purpose of basic operations. However, the modules acquire more complex abilities and functionality when operating under the command and coordination of the controller. 
       FIG. 4  is a system diagram illustrating a computing landscape  400  within a healthcare environment such as a hospital that includes modular medical device system  110 . Various devices and systems, both local to the healthcare environment and remote from the healthcare environment, can interact via at least one computing network  405 . This computing network  405  can provide any form or medium of digital communication connectivity (i.e., wired or wireless) amongst the various devices and systems. Examples of communication networks include a local area network (“LAN”), a wide area network (“WAN”), and the Internet. In some cases, one or more of the various devices and systems can interact directly via peer-to-peer coupling (either via a hardwired connection or via a wireless protocol such as Bluetooth or WiFi). In addition, in some variations, one or more of the devices and systems communicate via a cellular data network  435 . 
     The modular medical device systems  110  can include at least one communications interface that can access the computing network  405  either via a fixed wired connection or via a wireless connection (via, for example, one or more access points). In addition, the modular medical device system  110  can also couple to other components within the computing landscape  400  via direct wired or wireless peer-to-peer coupling (not shown). Furthermore, in some cases, one or more of the modular medical device system  110  can be self-contained and is not connected to any other devices or networks. The modular medical device system  110  can transmit data via the computing network  405  to any of the other components within the landscape  400  that characterizes the medical device modules  150 . In addition, the modular medical device system  110  can receive data from the computing network  405  relating to monitoring and in some cases controlling one or more attributes of the medical device modules  150  (e.g., software updates, configuration updates, historical data, status information, assets location, patient information, etc.). 
     In particular, aspects of the computing landscape  400  can be implemented in a computing system that includes a back-end component (e.g., as a data server  410 ), or that includes a middleware component (e.g., an application server  415 ), or that includes a front-end component (e.g., a client computer  420  having a graphical user interface or a Web browser through which a user may interact with an implementation of the subject matter described herein), or any combination of such back-end, middleware, or front-end components. A client  420  and servers  410 ,  415  are generally remote from each other and typically interact through the communications network  405 . The relationship of the clients  420  and servers  410 ,  415  arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. Clients  420  can be any of a variety of computing platforms that include local applications for providing various functionality within the healthcare environment. Example clients  420  include, but are not limited to, desktop computers, laptop computers, tablets, and other computers with touch-screen interfaces. The local applications can be self-contained in that they do not require network connectivity and/or they can interact with one or more of the servers  410 ,  415  (e.g., a web browser). 
     A variety of applications can be executed on the various devices and systems within the computing landscape such as electronic health record applications, medical device monitoring, operation, and maintenance applications, scheduling applications, billing applications and the like. As another example, the applications can comprise a collection of enterprise-based applications that provide dose error reduction software (DERS) for the modular medical device system  110  incorporates a role-based view of infusion data, provides a comprehensive platform for connectivity to external hospital applications, and enables directed maintenance and calibration activities for devices, storage of clinical and device history, etc. As a further example, the applications can provide for remote alarms management and/or asset tracking for medical device modules  150  coupled to one or more of the modular medical device system  110 . 
     The network  405  can be coupled to one or more data storage systems  425 . The data storage systems  425  can include databases providing physical data storage within the healthcare environment or within a dedicated facility. In addition, or in the alternative, the data storage systems  425  can include cloud-based systems providing remote storage of data in, for example, a multi-tenant computing environment. The data storage systems  425  can also comprise non-transitory computer readable media. 
     Mobile communications devices (MCDs)  430  can also form part of the computing landscape  400 . The MCDs  430  can communicate directly via the network  405  and/or they can communicate with the network  405  via an intermediate network such as a cellular data network  435 . Various types of communication protocols can be used by the MCDs  430  including, for example, messaging protocols such as SMS and MMS. In some cases, the MCDs  430  can receive alerts generated from the operation of the medical device modules  150  coupled to the backplane  120  and/or they can otherwise be used to monitor the operation of such medical device modules  150 . 
     Various types of medical device modules  150  can be used as part of the computing landscape  400 . These medical device modules  150  can comprise, unless otherwise specified, any type of device or system with a communications interface that characterizes one or more physiological measurements of a patient and/or that characterize or are used for the treatment of a patient. In some cases, the medical device modules  150  communicate via peer to peer wired or wireless communications with another medical device module  150  (as opposed to communicating with the network  405 ). For example, the medical device modules  150  can comprise a bedside vital signs monitor that is connected to other medical device modules  150  (and/or the modular medical device system  110 ), namely a wireless pulse oximeter and to a wired blood pressure monitor. One or more attributes of the medical device modules  150  can be locally controlled by a clinician, controlled via a clinician via the network  405 , and/or they can be controlled by one or more of a server  410 ,  415 , a client  420 , a MCD  430 , and/or another medical device module  150 , or the modular medical device system  110 . 
     The computing landscape  400  can provide various types of functionality as may be required within a healthcare environment such as a hospital. For example, a pharmacy can initiate a prescription via one of the client computers  420 . This prescription can be stored in the data storage  425  and/or pushed out to other clients  420 , an MCD  430 , and/or one or more of the medical device modules  150  forming part of the modular medical device system  110 . In addition, the medical device modules  150  and the modular medical device system  110  can provide data characterizing one or more physiological measurements of a patient and/or treatment of a patient (e.g., medical device module  150  can be an infusion management system, etc.). The data generated by the modular medical device system  110  and the medical devices  150  can be communicated to other medical device module  150 , the servers  410 ,  415 , the clients  420 , the MCDs  430 , and/or stored in the data storage systems  425 . 
       FIG. 5  is a logic diagram  500  of an intelligent inductive power system that can include one or more intelligent medical device modules  550  and an intelligent medical device system  510 . The intelligent medical device modules  550  and intelligent medical device system  510  can be included in computing landscape  400 . 
     Each intelligent medical device module  550  can be similar to the medical device module  150  shown in  FIGS. 1-3  and can include inductive receiver  552 , optical data transceiver  554 , data processor(s)  558 A, memory  557 , communications interface  559 , one or more sensors  560 , and intelligent power module  558 B. The one or more sensors  560  can include, for example, one or more temperature sensors and/or electrical sensors. 
     Each intelligent medical device module  550  can be inductively powered by intelligent medical device system  510 . Intelligent medical device system  510  can have a plurality of mounting seats to which intelligent medical device module  550  can be affixed. Like the mounting seats in modular medical device system  110 , each mounting seat in intelligent medical device system  510  can have an inductive transmitter  522 . Inductive transmitter  522  can provide non-contact powering of intelligent medical device module  550  via inductive receiver  552  when the intelligent medical device module is affixed to the mounting seat. If inductive receiver  552  is unable to adequately power intelligent medical device module  550 , optional secondary power source  556  in intelligent medical device module  550  can provide an alternative source of power to the medical device module. 
     Memory  557  of the intelligent medical device module  550  can include instructions for execution by the at least one data processor  558 A for use in the operation of the intelligent medical device module in a clinical setting. Additionally, memory  557  can also include instructions for execution by the at least one data processor  558 A for use in implementing the intelligent power module  558 B to monitor, store, and/or transmit one or more parameters/data of inductive receiver  552  to intelligent medical device system  510 . The intelligent medical device system  510  can, in turn, store these parameters/data in data storage systems  425 . For example, the parameters/data can include one or more of an inductive controller manufacturer ID, a firmware release ID, a link efficiency, a last error code, a device status, an input voltage, an input current, an output power, a temperature, and other sensor data. In some implementations, more than one inductive receiver  552  can be provided, and one or more of the above parameters/data can be provided for each inductive receiver. In some implementations, a communication link to the intelligent medical device system  510  can be provided via a serial bridge to exchange the parameters/data and control values over this bridge. In some implementations, the intelligent power module  558 B (e.g. using data processor (s)  558 A) can be configured to determine one or more of a link current, efficiency, and temperature operating state of each inductive receiver  552  based upon special instructions and feedback loops to implement these features. 
     In some implementations, the one or more parameters/data of the intelligent medical device module  550  can be transmitted (e.g. alternatively or in addition to the serial bridge) over the optical data transceiver  554  to intelligent medical device system  510 . In some implementations, the one or more parameters/data can be transmitted (e.g. alternative or in addition to the serial bridge and/or the optical data transceiver  554 ) using a near field magnetic induction communication system via the inductive receiver  552  and the inductive transmitter  522 . The one or more parameters/data of the intelligent medical device module  550  can be transmitted in response to one or more queries/interrogations from the intelligent medical device system  510 . In some implementations, intelligent medical device module  550  can automatically transmit the one or more parameters/data to intelligent medical device system  510  without waiting for a query/interrogation from the medical device system. For example, intelligent medical device module  550  may be configured to transmit the one or more parameters/data to intelligent medical device system  510  at predetermined time intervals or upon the occurrence of a particular event. These events can occur, for example, when intelligent medical device module  550  is powered on, when intelligent medical device module  550  receives data, and the like. 
     In some implementations, each intelligent medical device module  550  can also comprise an additional communications interface  559  other than the optical data transceiver  554 . Communications interface  559  may be needed in implementations where optical data transceiver  554  is not part of the intelligent medical device module  550 . In these implementations, communications interface  559  can be the only gateway for communication outside of the intelligent medical device module  550 . The communications interface  559  can be fixed and/or wireless and can be used to communicate to computer networks and peer-to-peer pairing with other devices when the intelligent medical device module  550  is not coupled to the backplane  120 . In some implementations, the communications interface  559  can be used in addition or instead of the optical data transceiver  554  when the intelligent medical device module  550  is coupled to the backplane  120 . For example, the intelligent medical device module  550  can be seated on the backplane  120  but not have an optical data transceiver. In such a scenario, the communications interface  559  can wirelessly communicate with one or more data processors  541  of the controller of the intelligent medical device system  510  so that the one or more parameters/data can be monitored and/or controlled by the medical device system  510 . 
     The intelligent medical device system  510  can be similar to the modular medical device system  110  shown in  FIGS. 1-2 , and can include a power source  560 , optical data transceiver  526 , one or more inductive transmitters  522 , data processor(s)  541 , communications interface  542 , memory  545 , one or more sensors  513 , and intelligent power module  515 . In some implementations, the data processor(s)  541 , memory  545 , and the intelligent power module  515  may be part of the control unit  140 . In some implementations, intelligent medical device system  510  can transmit parameters/data received from intelligent medical device module  550 , such as parameters/data from inductive receiver  552 , to servers  410  and  415 , clients  420 , the MCDs  430 , other intelligent medical device modules, and other intelligent medical device systems using communications interface  542 . In some implementations, intelligent medical device system  510  can save parameters/data received from intelligent medical device module  550  to data storage systems  425 . 
     In some implementations, the intelligent medical device system  510  can include memory  545  which includes instructions for execution by the at least one data processor  541  for use in receiving the one or more parameters/data from each intelligent medical device module  550 . The received parameters/data may relate to an inductive receiver  552  in each intelligent medical device module  550 , for example. 
     Memory  545  can also include instructions for execution by data processor  541  to access, receive, or determine one or more parameters/data from inductive transmitter  522 . For example, the parameters/data of the inductive transmitter  522  can include an inductive controller manufacturer ID, a firmware release ID, a link efficiency, a last error code, a device status, an input voltage, an input current, an output power, a temperature, and other sensor data. In some implementations, the intelligent power module  515  (e.g. using data processor(s)  541 ) can be configured to determine one or more of a link current, efficiency, and temperature operating state of each inductive transmitter  522  based upon special instructions and feedback loops to implement these features. In some implementations, intelligent medical device system  510  can transmit the parameters/data of inductive transmitter  522  to servers  410  and  415 , clients  420 , the MCDs  430 , other intelligent medical device modules, and other intelligent medical device systems using communications interface  542 . In some implementations, intelligent medical device system  510  can save parameters/data of inductive transmitter  522  to data storage systems  425 . 
     Application server  415  can host a remote maintenance application that allows a user (e.g., maintenance personnel) to remotely conduct maintenance tests on intelligent medical device module  550 . Unlike conventional maintenance applications which may require a user to be in the same location as the medical device module when performing maintenance tests, the remote maintenance application allows a user to administer these tests remotely via network  405 . 
     A user, such as a remote technician, can launch the remote maintenance application using any of clients  420  and/or MCDs  430 .  FIG. 6  illustrates a process  600  for using the remote maintenance application. 
     At  610 , the remote maintenance application can authenticate the identity of the user in order to prevent unauthorized testing of intelligent medical device modules  550 . During the authentication process, the remote maintenance application can prompt the user to enter a username and password. The remote maintenance application can cross reference the received authentication information against a list of personnel authorized to use this application. Alternatively or additionally, the remote maintenance application can associate the received authentication information with a role performed by the user. This role can, for example, correspond to the user&#39;s title or position. Only users having a specific role may be allowed to use the remote maintenance application. For example, maintenance personnel may be authorized to use the remote maintenance application while laboratory personnel may not. Role information as well as the list of personnel authorized to use the remote maintenance application can be stored at data storage systems  425  or at application server  415 . 
     At  620 , the authenticated user can make a request to conduct tests on an intelligent medical device module  550  and/or the mounting seat to which the intelligent medical device module is affixed. This request can be entered into the remote maintenance application. Because computing landscape  400  can include many intelligent medical device modules  550 , the user may be prompted to identify the particular intelligent medical device module to be tested. The intelligent medical device module  550  can be identified using, for example, the intelligent medical device module&#39;s IP address, the IP address of the intelligent medical device system  510  to which the intelligent medical device module belongs in combination with other identifying information (e.g., the module&#39;s mounting seat position), a network name and/or device name, and the like. 
     The user&#39;s request can also identify one or more tests to be conducted on the intelligent medical device module  550  and/or the mounting seat to which it is affixed. These tests can be selected from a predetermined set of maintenance tests that are designed to measure various parameters associated with inductive receiver  552  and/or the inductive transmitter  522 . These parameters can include a link efficiency, an input voltage, an input current, an output power, and a temperature. Alternatively or additionally, these tests can measure parameters related to the operation of the intelligent medical device module  550 . For example, if intelligent medical device module  550  is an infusion pump, these tests can measure the maximum pressure of the pump, the maximum infusion rate, and the like. While many of these tests can be conducted automatically, some of these tests may require manual assistance from an operator. The request can identify whether the tests require human intervention. 
     At  630 , a call or connection can be established with the intelligent medical device module  550  to be tested. Establishing this call allows client  420  or MCD  430  on which the remote maintenance application is running to exchange information with intelligent medical system  510  and intelligent medical device module  550 . In order to establish the call with the correct device, the user can enter the identity of the intelligent medical device module  550  or the intelligent medical device system  510  to which it belongs using the identifying information described above with respect to  620 . Alternatively, the remote maintenance application can pull this identifying information from the request received at  620 . The remote maintenance application can then use this information to set up the call. Once this call is established, the remote maintenance application can transmit the request to intelligent medical device system  510  which, in turn, can transmit this request to intelligent medical device module  550 . In some implementations, the remote maintenance application can directly transmit this request to intelligent medical device module  550 . 
     Before testing can begin, the remote maintenance application can verify that the intelligent medical device module  550  to be tested is not currently being used to treat a patient. This precaution can prevent the unwanted testing of a device while it is being used for clinical purposes. At  640 , the remote maintenance application can receive this indication from the intelligent medical device module  550  and/or the intelligent medical device system  510 . This indication can be sent, for example, while the intelligent medical device module  550  is in standby mode or if the intelligent medical device module has not experienced a change in operating state during a predetermined period of time. In some implementations, an assistant located at intelligent medical device module  550  can verify that the intelligent medical device module is not being used to treat a patient and send an indication of the same to the remote maintenance application. 
     At  650 , the tests identified in the request can be conducted on the intelligent medical device module  550  or the mounting seat to which it is affixed. As explained above, while many of these tests can be conducted automatically, some tests may require operator assistance. Tests that can be conducted automatically include, for example, the measuring of voltage, temperature, or other sensor data at inductive transmitter  522  and inductive receiver  552  using sensors  513  and sensors  560 , respectively. Tests that require operator assistance include, for example, maximum pressure tests on an infusion pump. For these tests, an operator may need to manually pump the device to occlusion before its pressure can be measured by a pressure sensor. 
     At  660 , the remote maintenance application can receive test data based on the tests conducted at  650 . The intelligent medical device system  510  to which the intelligent medical device module  550  belongs can transmit this test data to application server  415 . Test data can be sent to application server  415  at periodic intervals during testing or in a single message after testing has finished. Application server  415  can, in turn, provide or transmit the test data to the client  420  and/or the MCD  430  running the remote maintenance application. In some implementations, intelligent medical device system  510  can provide or transmit this test data directly to the client  420  and/or the MCD  430 . Client  420  and/or the MCD  430  can load, store, or display the test data to the user. 
     With regard to the test data, the remote maintenance application can vary the amount of detail that is provided to a user based on the user&#39;s role. For example, maintenance personnel (i.e., those responsible for maintaining and/or fixing intelligent medical device modules  550 ) may need access to more detailed test data than laboratory personnel (i.e., those who merely monitor and/or use intelligent medical device modules). While raw test data values can be provided to the former, less detailed test data can be provided to the latter (e.g., changes in data values over time). The remote maintenance application can determine the user&#39;s role and, consequently, the type of test data to be provided to the user based on the authentication information received at  610 . 
     The user can analyze the test data provided at  660  to determine whether the tested intelligent medical device module  550  or the mounting seat to which it is affixed is functioning properly. In some implementations, the user can request operational data from the remote maintenance application. Operational data can include data relating to the day-to-day operation of the intelligent medical device module  550  or the mounting seat to which it is affixed and may not include data generated during testing as described herein. The remote maintenance application can retrieve operational data from data storage systems  425  and provide this data to the client  420  and/or MCD  430 . In some implementations, the remote maintenance application can be configured to compare the test data with the operational data and identify performance trends from this data. 
     These trends can reveal a progression over time towards undesirable conditions such as higher operating currents, higher operating temperature, and the like which, in turn can trigger the need for additional tests or maintenance. For example, a motor in an infusion pump may be known to require a certain amount of power to operate the pump. If it is determined that the motor gradually requires more current over time to operate the pump, then a user may want to conduct additional tests at  670 . The user can enter a request for additional tests into the remote maintenance application which, in turn, can transmit this request to the intelligent medical device system  510 . This request can identify the intelligent medical device module to be tested and the types of tests to be conducted. For example, if the user determines that the motor in an infusion pump is not functioning properly, the user can enter a request into the client  420  and/or MCD  430  running the remote maintenance application. This request can identify the particular infusion pump to be tested as well as the nature of the test (e.g., a test to determine whether the motor needs to be replaced). The remote maintenance application can transmit this request to the infusion pump across networks  405  or  435 . In some implementations, intelligent medical device system  510  can receive this request from the remote maintenance application and forward the request to the infusion pump to be tested. The infusion pump can display a message indicating a request for testing. Because this request may require assistance from an operator, the request can indicate whether human intervention is needed. An operator located at the pump can receive this request and replace the infusion pump&#39;s motor as indicated in the request. 
       FIG. 7  illustrates a process  700  for using a remote maintenance application. 
     At  710 , the remote maintenance application can receive a request to conduct one or more tests on a medical device module that is part of a medical device system. In some implementations, the medical device module can have an inductive receiver and correspond to the intelligent medical device module  550 . The medical device system can correspond to the intelligent medical device system  510 . The medical device system can include an inductive backplane having a plurality of mounting seats, each mounting seat having an inductive transmitter. The inductive backplane can be configured to inductively power the medical device module when the medical device module is affixed to a first mounting seat. The tests conducted on the medical device module can relate to an attribute of the inductive receiver on the medical device module or the inductive transmitter on the first mounting seat. The tests can also relate to the operation of the medical device module. 
     At  720 , the remote maintenance application can transmit a message representative of the request to the medical device system. This message can identify the medical device module to be tested, the types of test to be conducted, and whether operator assistance is needed. 
     At  730 , the remote maintenance application can receive test data based on the tests conducted on the medical device module and/or the mounting seat to which it is affixed. 
     At  740 , the remote maintenance application can provide the test data to the user by transmitting, loading, storing, or displaying the test data on a client and/or MCD running the remote maintenance application. In some implementations, the remote maintenance application can vary the type of test data that is provided to the user based on the user&#39;s role.
