[0031] Modular patient care systems may pose safety risks, such as improper module securing or accidental impact, which could lead to interruptions in operation or patient care. These systems may also operate with high currents or in environments exposed to therapeutic fluids or bodily fluids, posing a risk of damage to electrical connection interfaces due to moisture or electric arcing between modules.

[0032] Figure 1A-1B An example of a modular patient care system 10 according to some embodiments is shown. Figure 1A A front view of a modular patient care system 10 is shown, which includes an interface module 100 and a functional module 150 in an attachment configuration. Figure 1B A rear view of a modular patient care system 10 is shown, which has only an interface module 100 in a separate configuration.

[0033] The modular patient care system 10 is an example of a modular system that can employ any attachment technology further described herein in conjunction with other figures. The modular patient care system 10 includes multiple modules or units, such as interface module 100 and one or more functional modules 150, which may be releasably or detachably coupled together.

[0034] Interface module 100 may be configured to perform one or more of the following functions in patient care system 10: (i) it may provide a physical base for the system attached to a structure such as an intravenous (IV) bar or bed rail; (ii) it may supply power to components of the system, such as, for example, one or more functional modules 150; (iii) it may provide an interface between the system and external devices; and / or (iv) it may provide a main or centralized user interface for the system. Interface module 100 may include input / output (I / O) devices that may be configured to interact with a user. Figure 1A The I / O devices shown include a display device 102 and buttons, including hard keys 104 and soft keys 106. Although a display and buttons are shown, it is conceivable that the modular patient care system 10 or any module thereof may include or be coupled to any suitable I / O device to allow the user to observe or control, for example, one or more speakers, microphones, motion sensors, touch sensors, pointing devices, or depth sensors.

[0035] Display device 102 can be implemented as any suitable type of information display, such as, for example, a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, or a micro LED display. Display device 102 can be configured for use in setup and operation procedures to facilitate data input and editing. Display device 102 can also be used to display various operating parameters, such as, for example, the injection volume (VTBI) of a single functional module 150, the current time, prompts, suggestions, and / or alarm status.

[0036] As noted, interface module 100 is shown with a plurality of hard keys 104 and soft keys 106, which can be used to input data and commands. The numeric hard keys 104 can be configured to input numeric data, while the remaining keys of hard keys 104 and soft keys 106 can be configured to input operation commands. Soft keys 106 are shown arranged along the edge of display device 102 to interact with information presented on display device 102 to define the function of a particular soft key 106 at any given time. Thus, when a particular soft key 106 is pressed, it may allow selection of options or display of infusion or monitoring parameters on display device 102 adjacent to the particular soft key. As noted, hard keys 104 can also be used to input specific operation commands. For example, when a particular hard key is pressed, it may be configured to, respectively, change the system from standby mode to operating mode, temporarily disable the audio function of interface module 100, or allow the user to access available system or function module options, and other possible commands.

[0037] like Figure 1A As shown, the interface module 100 may also include one or more indicators for providing indications of various statuses or other information of the module. In Figure 1, the interface module 100 is shown with three indicators, including a communication indicator 114, an external power indicator 116, and an internal power indicator 118. The communication indicator 114 may be configured to indicate that the system is communicating with a compatible external computer system. The external power indicator 116 may be configured to indicate that the interface module 100 is connected to and operates with an external power source. The internal power indicator 118 may be configured to indicate that the interface module 100 is operating using an internal power source (e.g., a battery). For example, each indicator may include a light source such as a light-emitting diode (LED), which is configured to emit light to provide a corresponding indication when a corresponding status occurs.

[0038] The modular patient care system 10 may also include one or more external communication interfaces 120. Figure 1B In the example shown, the communication interface 120 is located at the rear of the interface module 100. The communication interface 120 can be, for example, an industry-standard wireless network memory card or a PCMCIA (Personal Computer Memory Card International Association) slot for accommodating PCMCIA cards, although those skilled in the art can choose from a variety of commercially available communication protocols or industry standards. The modular patient care system 10 may also include one or more interface ports 122. Figure 1B In the example shown, interface port 122 is located at the rear of interface module 100. Interface port 122 may include, for example, an industry-standard RS-232 port and / or RJ45 port, although, similarly, those skilled in the art can choose from a variety of commercially available communication protocols or industry standards. Furthermore, although as... Figure 1A-1BThe example shown is described as including communication interface 120 and interface port 122, but any number or combination of communication interfaces and / or ports can be included in various embodiments of interface module 100.

[0039] For example, communication interface 120 and / or interface port 122 may be used to download drug libraries, drug delivery profiles, other system configuration values, and / or may be used to upload event history data from interface module 100. Additionally or alternatively, communication interface 120 and / or interface port 122 may serve as an interface to a patient monitoring network and nurse call system, or as an interface to an external device (such as a barcode reader) to provide means for inputting drug and / or patient information from drug or patient records. In some embodiments, interface port 122 and / or communication interface 120 may be supplemented with one or more peripheral device ports, such as a patient-controlled analgesia (PCA) port. The PCA port may provide connectivity to a remote handheld dose request button, which the patient can use to request a drug dose during PCA application.

[0040] like Figure 1B As shown, the interface module 100 may also include a clamp 170 for attaching the interface module 100 to a structure such as an IV stent or a hospital bed. Figure 1B In the example shown, clamp 170 is positioned on the rear surface of interface module 100. Clamp 170 can be any clamp suitable for attaching bedside patient monitoring or infusion devices to these structures.

[0041] Figure 1A Functional module 150 is also shown. It should be understood that, although... Figure 1A Only a single functional module 150 is shown, but the modular patient care system 10 can be configured to allow the use of the module attachment mechanism described herein, and to attach any number of functional modules 150 to either side or both sides of the interface module 100 in any order. The type and number of functional modules 150 attached to the interface module 100 can be any suitable number based on the wiring and the physical and electrical capabilities of the interface module to handle the required type and number of functional modules. Functional modules 150 can be selected from a variety of functional devices, including devices for patient treatment and / or patient monitoring. For example, functional module 150 can be an infusion pump module, PCA module, syringe pump module, pulse oximeter module, invasive or non-invasive blood pressure monitoring module, electrocardiograph module, barcode or ID reader module, printer module, temperature monitoring module, radio frequency (RF) telemetry link module, fluid heater / IV pump module, or high-rate IV pump module (e.g., 2000+ ml / hr). It is also conceivable that functional module 150 can be adapted for other uses.

[0042] Each functional module 150 may include a channel position indicator 155, which identifies the position of the functional module within the modular patient care system 10. For example, the modular patient care system 10 may include four channel positions A, B, C, and D. When the four functional modules are attached to the system, the functional modules may be located in one of the four channel positions A, B, C, and D, and the channel position indicator 155 on each individual functional module can visually indicate the corresponding channel position. Starting with the first module on the left, the channel positions can be designated AD. The positions of each functional module relative to each other or relative to the interface module 100 can be interchanged, but the channel positions AD can remain in the same position.

[0043] Figure 2 An example of four functional modules attached to interface module 100 is shown according to some embodiments. Regardless of which module is placed immediately to the left of interface module 100, that module can always indicate channel position B on channel position indicator 155. Each functional module may also contain certain function-specific information transmitted to interface module 100 to indicate the type of functional module at each channel position. Each functional module 150 may also have one or more buttons, such as selection keys 156 that allow module selection.

[0044] exist Figure 2 In the example shown, the modular patient care system 10 includes four distinct functional modules: a pulse oximeter module 150A at location A, an infusion pump module 150B at location B, a PCA module 150C at location C, and an infusion pump module 150D at location D. The corresponding location of each functional module is indicated by an indicator 155 on the functional module. Due to the use of four functional modules, the display device 102 on the interface module 100 indicates A through D. The system can be configured to allow selection of functional modules, with the interface module 100 executing a specific function or procedure by pressing the appropriate soft key 106 adjacent to the desired, indicated channel and functional module. Alternatively or additionally, the system can be designed to select a specific functional module by pressing the selection key 156 located on the desired functional module. When the desired functional module is selected, the display device 102 of the interface module 100 can be configured to act as the user interface for the selected functional module. For example, the display device 102 can be configured according to a specific functional domain to provide a function-specific display and soft keys based on the selected functional module.

[0045] Figure 2The illustrated infusion pump module 150D is a pump device for basic infusion. The infusion pump module 150D may include a control system to control various functions performed by such a pump, including controlling fluid delivery to the patient and monitoring for blockages or air bubbles in the fluid path. In the illustrated example, the infusion pump module 150D includes two display devices: a rate display 154 for displaying the actual infusion rate during pump operation, and a channel message display 152 for displaying information, consultation, alarms, or fault messages.

[0046] The infusion pump controller may also include input devices, such as hard keys for data and command input. The selection key 156 of the infusion pump module 150D may be implemented as a hard key and can be configured to allow the user to select a channel for inputting infusion parameters. Other input devices, such as other hard keys, when pressed, may be configured to, for example, pause the infusion during infusion, resume a previously paused infusion, or stop the infusion occurring on the channel, deselect the channel, and, if the function module on the channel is the only operating function module, turn off the system power. The infusion pump module 150D may include one or more indicators that illuminate when a function module is in an alarm or infusion completion state, when a function module is programmed for a future start-up time or has been paused, or when a function module is performing an infusion. Other suitable indicators may be included in other function modules.

[0047] Figure 2The diagram also shows a pulse oximeter module 150A, an infusion pump module 150B, and a PCA module 150C. As shown, each of these modules includes a set of buttons, such as hard keys similar to those on the infusion pump module 150D. The pulse oximeter module 150A is a pulse oximeter device and includes or is coupled to a peripheral device containing a pulse oximeter sensor 199, which can be directly coupled to the patient to measure oxygenation in the patient's blood. The infusion pump module 150B is a pump device for precise fluid delivery and may include a syringe for manual infusion and a syringe plunger. For example, the infusion pump module 150B is shown with a syringe holder 151B configured to hold the syringe. The PCA module 150C is a drug delivery device and includes or is coupled to a peripheral device containing a dose request button 197, which can be pressed directly by the patient to request a drug dose or trigger the delivery of an analgesic dose. PCA module 150C may also include a door lock 161 for providing security for sealing anesthetics or other substances to be infused. PCA module 150C is also shown with a syringe holder 151C configured to hold a syringe therein. Furthermore, pulse oximeter module 150A, infusion pump module 150B, and PCA module 150C each include one or more displays and one or more indicators that can be used to present appropriate information.

[0048] In modular systems such as the modular patient care system 10, releasable or detachable module attachment mechanisms can be employed to allow for customization or reconfiguration during use, while providing electrical and mechanical connectivity when the module is attached. Figure 1A-2 In the example shown, electrical connectors and latching mechanisms can be located on opposite sides of each module (including interface module 100 and each functional module). In a linear arrangement where modules are stacked side-by-side in a row, such mechanisms can be used to directly attach any functional module to the interface module, or to directly attach any functional module to any other functional module. These attachment mechanisms provide physical support for the attached functional module and also provide power and internal communication connectivity between interface module 100 and the functional module. Attachment mechanisms across different modules can be identical to each other so that each module can mate with another module. Optionally, some attachment mechanisms can prevent accidental connection between two interface modules 100.

[0049] Figure 3 A modular patient care system 10 is shown during an example attachment process or sequence that can be used to releasably attach a pair of modules to each other. Figure 3 A front view of a system in which the left side 260 of functional module 150 is attached to the right side 250 of interface module 100 is shown. Figure 3As shown, the upper portion of functional module 150 may include a retaining component 210 on its left side, which can engage with a complementary retaining component on the upper portion of the right side of an adjacent module. The retaining component 210 can be engaged by moving the left side 260 of functional module 150 at an angle to the right side 250 of interface module 100, so that the retaining component 210 of the functional module can engage, secure, or insert into the complementary retaining component of interface module 100. When the retaining components engage or lock, the engaging retaining components or upper portions of the adjacent modules can then provide anchoring or pivot points for the functional module 150 to rotate about it. As the functional module 150 rotates (e.g., about the retaining component 210 in the direction of arrow 214), the lower portion of functional module 150 can be secured against the lower portion of interface module 100 to engage a latching mechanism 212 at the lower portion of functional module 150 with a complementary mechanism at the lower portion of interface module 100. When latching mechanism 212 latches engaged, adjacent modules can be secured in a side-by-side arrangement (e.g., as shown in the diagram). Figure 1A (As shown). These steps can be performed by a user (e.g., a doctor or technician) grasping and manipulating the functional module 150 to move the functional module and fix adjacent modules together.

[0050] Figure 4-7 Various views of the mechanical and electrical attachment mechanisms for a modular patient care system 10 according to some embodiments are shown. Figure 4 A right perspective view is shown. Figure 5 The right view is shown. Figure 6 The left perspective view is shown, and Figure 7 The bottom view is shown, in which each figure shows a modular patient care system 10 with multiple functional modules 150 attached together. Figure 8-12 Enlarged views of various components of the attachment mechanism according to some embodiments are shown.

[0051] As shown in the figure, each functional module 150 may include a housing or enclosure 218, which may house the module's internal components, such as, for example, one or more processors, memory, batteries, power supplies, circuitry, pumps, and / or motors. Attachment mechanisms are arranged on opposite sides or opposite side surfaces of each housing 218 to allow the housings to be attached together in a side-by-side arrangement. The mechanical and electrical attachment mechanisms include a mechanical retaining member 210, an electrical connector 220, and a latching mechanism 212, and are located on the opposite attachment sides of each housing 218 and configured to engage with each other to secure the attachment sides of adjacent modules together. The mechanisms shown can be configured to facilitate, as described above... Figure 3The attachment sequence is as shown and described. Actuator 224 is coupled to latching mechanism 212 of each module 150 and can be operated to release or detach the module from adjacent modules attached to its right 250 and / or its left 260. Although these mechanisms are described with respect to functional module 150, it is contemplated that these mechanisms can be applied to any other suitable module in the module system, including, for example, interface module 100.

[0052] refer to Figure 4-7 Each housing 218 is shown as a generally rectangular box shape having a front side 270, a rear side 280, a right side 250, and a left side 260. The front side 270 corresponds to the front side of module 150 (e.g., as shown in the image). Figure 1A As shown, the rear side 280 is opposite to the front side and corresponds to the rear side of the module. The left side 260 and the right side 250 are adjacent to the front side 270 and the rear side 280, respectively, wherein the left side 260 corresponds to the left side of the module when viewed from the front side 270, and the right side 250 is opposite to the left side 260 and corresponds to the right side of the module when viewed from the front side 270. The left and right sides correspond to the attachment sides of the module configured to cooperate with the complementary attachment sides of adjacent modules.

[0053] On each attachment side, i.e., the left side 260 and the right side 250 in this example, the retaining assembly 210 is located at the upper end portion 232 of the housing 218, and the latching mechanism 212 is located at the lower end portion 234 of the housing 218. An electrical connector 220 is shown as a connector separate from the latching mechanism 212 and the retaining assembly 210, located between the latching mechanism 212 and the retaining assembly 210, and closer to the latching mechanism 212 than the retaining member 210. An actuator 224 is implemented as a mechanically actuated button coupled to the latching mechanism 212 and located at the bottom end portion 234 of the front side 270 of the housing 218.

[0054] The retaining components 210 are configured to cooperate with each other to provide structural support to the ends of adjacent modules, without being configured to lock them together. Figure 8 As further shown in the enlarged view, the retaining components 210 include features that allow them to slide into each other to facilitate support of the corresponding ends of the retaining modules. Each retaining component 210 may include one or more protrusions 342 and one or more recesses 344, each recess being configured to receive a protrusion from an adjacent retaining component that is slidably inserted therein. Figure 8In this embodiment, the protrusions 342 and recesses 344 have circular profiles, which improves the ease with which the protrusions 342 slide into the recesses 344. Furthermore, multiple protrusions 342 and multiple recesses 344 (each in this case, a pair) are shown arranged across the width of the retaining assembly 210, with the recesses inserted between the protrusions and vice versa. This enhances the support balance provided by the retaining assembly across the width of the attachment side compared to embodiments utilizing only one protrusion and one recess on each retaining assembly. The retaining assembly 210 may be made of a conductive material (e.g., metal) or otherwise incorporate a conductive material so that the retaining assembly can provide a grounding path between the attached modules.

[0055] Electrical connector 220 is configured to provide an electrical connection between adjacent modules during mechanical attachment. For example... Figure 9 As further shown in the enlarged view, each of the electrical connectors 220 may include multiple contacts 358 providing multiple corresponding channels for exchanging signals between modules. Each channel may correspond to a specific signal, such as a ground connection, data connection, or power connection. The contacts 358 of adjacent connectors 220 are configured to make current contact with each other when adjacent modules are mechanically engaged or attached together to allow signal exchange between them.

[0056] The latching mechanism 212 is configured to mechanically fasten adjacent modules together via latching engagement between adjacent modules. Figure 10-11 It shows Figure 4-7 An enlarged view of the example latching mechanism 212, in which Figure 10 This is a top side view. Figure 11 This is the bottom side view. Figure 12 An enlarged view of the latching mechanism 212 in an engagement configuration is shown, wherein the latching mechanism 212 is locked to an adjacent module.

[0057] like Figure 10-12 As further shown in the enlarged view, each latching mechanism 212 may include a catch member 242 and a movable engagement member 252 configured to engage and lock onto the catch member 242 of an adjacent module. Each of the engagement member 252 and the catch member 242 may include complementary hook features 266 that engage with each other to securely hold the latch in the engagement configuration. An actuator 224 may include an actuation button fixed to an assembly of the latching mechanism and configured to move or translate an assembly of the latching mechanism. Movement of the latching mechanism 212 based on operation of the actuation button can release the hook features 266, disengaging the engagement member 252 from the catch member 242. Figure 4-7In the example shown, fastener 242 is located on the right side 250 of each module, while engaging member 252 is located on the left side 260 of each module and is configured to engage with fastener 242 of the adjacent left-side module. Other arrangements are contemplated, including, for example, a reverse arrangement where fastener 242 is on the left and engaging member on the right. Furthermore, while fastener 242 is shown as part of a latching assembly attached to housing 218, it is contemplated that fastener 242 could be implemented as a fixing part of housing 218, for example, where hook feature 266 is formed as an integral part of housing 218.

[0058] While a specific arrangement of the attachment components on the left and right sides of the housing is shown, it is conceivable that various other arrangements, configurations, and positions of these attachment components are possible. For example, the positions of the latching mechanism 212 and the retaining component 210 may be reversed relative to the upper and lower portions, such that the retaining component 210 is located at the lower portion 234 and the latching mechanism 212 is located at the upper portion 232. As another example, these components may be located on other opposing or non-opposing sides of the housing 218 for other types of attachment or coupling configurations of the group of modules.

[0059] Figure 13 This is a schematic diagram illustrating an example of an interface module 100 according to some embodiments. Figure 13 In the example shown, interface module 100 includes a power input 268 for receiving power from an external power source and forwarding that power to power source 258. Interface module 100 also includes an internal power source 262, which can be used to maintain power to system functions, including memory, when interface module 100 is disconnected from the external power source. Power source 258 can convert power from external power input 268 or internal power source 262 to a voltage suitable for system operation. Power management unit 254 can control the switching between the two power sources, control the charging of internal power source 262, monitor the remaining capacity of internal power source 262, monitor system power consumption under battery operation, and estimate the remaining system runtime on internal power source 262 using system power consumption and remaining battery capacity. Power source 258 can also supply power to the rest of the system and audio alarm 261 via power ports 278 and 279, thereby providing the system's audio functionality.

[0060] The microprocessor 264 and memory 251 can receive and process data and commands from the user, as well as communicate and control with functional module 150 and other devices outside the system. It should be understood that memory 251 and other memories in the patient care system can be any type of memory or any combination of erasable and reprogrammable memories. Examples of such memories include, but are not limited to, random access memory (RAM) with a backup battery and flash electronically erasable programmable read-only memory (Flash EEPROM). Backup battery 256 can power memory 251 to maintain the information stored in memory in the event of a power outage at power input 268 and internal power supply 262. Interface module 100 also includes a keyboard 267 (which includes hard keys 104 and soft keys 106) and a display device 102, as combined with... Figure 1A-2 As stated above.

[0061] Power ports 278 and 279, powered by power supply 258, can supply power to functional module 150 via connector 220. Connector 220 may also include internal communication ports 283 and 281, which provide data and command interfaces with the attached functional unit 150, respectively. Ports 283 and 281 can be controlled by internal communication controller 272, which in turn can be controlled by microprocessor 264. Finally, external communication controller 274 can control the command and data flow through interface port 122, while microprocessor 264 can directly control communication interface 120.

[0062] Figure 14 This is a schematic diagram illustrating an example of a functional module according to some embodiments. In this example, the functional module is configured as an infusion pump module 150A. Figure 14 Various aspects of the control system of the infusion pump module 150A are shown. The display device 359 may include a rate display 154, a channel display 152, and a combination of... Figure 2Various visual indicators 164 are discussed. The keyboard 354 may consist of various buttons including hard keys as described above, and may be controlled by a keyboard / display controller 362 together with the display device 359. The support processor 360 and associated memory 368 may be configured to receive and process data and commands from the user, and to communicate with attached interface modules. For example, the support processor 360 and memory 368 may be configured to perform calculations for a specified infusion using infusion data input by the user. The memory 368 may have a backup battery 376 to maintain information stored in the memory when the functional modules do not receive power from an external power source. The backup battery 376 may also be used to power an audio alarm 350, which can signal when the infusion is completed or the main power supply fails. The power management unit 352 may obtain power from power ports 380 or 381 included in electrical connectors 220 that connect functional modules to interface modules or other functional modules. Electrical connectors 220 may be connected via power lines 377 and distribute power to components of the infusion pump module 150A. Similar to interface module 100, infusion pump module 150A may also include an internal communication controller 357, which can be configured to send or receive data or commands from the interface module via communication line 379 and communication ports 382 and 383, and may also be included in electrical connector 220. These power and communication ports, connected via power and communication lines, allow functional units to be connected side-by-side, but still communicate with the interface module through an intermediate functional module, rather than being directly attached to the interface module.

[0063] The infusion pump unit 150A may also include components that facilitate pumping, such as a motor controller 364 for controlling the pump motor 366 and a sensor controller 372 for acquiring indications from a sensor 374. The sensor 374 can be used to detect pump mechanism speed and fluid pressure, air bubble ingress, and flow cessation. For example, the motor controller 364 and the pump motor 366 may include any suitable peristaltic pump motor / motor controller combination. The pump motor 366 can be configured to push fluid from a reservoir through an infusion set to a vascular access device (e.g., a catheter) by peristaltic motion. It is conceivable that a variety of commercially available reservoirs, infusion sets, vascular access devices, and other infusion materials can be used in conjunction with the infusion pump module 150A.

[0064] The sensor controller 372 can be configured to receive signals from the sensor 374, such as sensing the direction and speed of the pump motor, the presence of air bubbles in the fluid path, the pressure in the fluid path, the open or closed state of the pump door, the open or closed state of the flow stop device, and / or the movement of the latch mechanism, and forward this information to the support processor 360. If the support processor 360 determines that an unwanted or other predetermined event is occurring, the support processor can take further actions, such as placing the pump unit 150A in an advisory or alarm state, stopping the infusion, shutting down the pump unit, and / or forwarding the information to the attached interface module to achieve a complete system shutdown.

[0065] Safety processor 378 can be configured to monitor these same signals from sensor 374. Safety processor 378 can also receive pump operating parameters from support processor 360, such as the current infusion rate, VTBI, and fluid path pressure alarm limits. Safety processor 378 can be configured to independently calculate values, such as the appropriate motor speed from these parameters, and use these values ​​to monitor sensor 374 for correct pump motor direction and speed, the presence of air in the fluid path, fluid path pressure, the open or closed state of the pump door, and the open or closed state of the flow control device. When safety processor 378 determines that an unexpected event is occurring, it can forward this information to support processor 360 for further action, or the safety processor can independently shut down the functional module.

[0066] The infusion pump module 150A (or any other functional module 150) can be configured without a local power supply (except for the aforementioned memory retention and audio alarm functions), and therefore may not be able to continue operation in the event of a mains power failure, such as when the functional module is detached from the interface module. This ensures that the functional unit will not be operated without the safety and control functions provided by the interface unit. Furthermore, the simplified commands available directly at the pump functional unit are not intended to replace the interface capabilities of the advanced interface unit 100 or the basic interface unit 200. However, when power and necessary input values ​​(such as VTBI and infusion duration) are provided from the interface unit, the infusion pump unit functions as a functional unit capable of controlling all aspects of the infusion.

[0067] Interface module 100 may also include sensor 374 configured to detect mechanical movement of latching mechanism 212. The latching sensor may be configured to detect movement of the latching mechanism indicating engagement and / or disengagement of latching mechanism 212 with an adjacent module. The latching sensor may be used alone or in combination with electrical information detected via electrical connector 220 to determine when the interface module is attached to or disengaged from an adjacent module. Such signals may be used by a system processor (e.g., support processor 356) to enforce engagement of the latching mechanism before allowing core functions of the module (e.g., pumping operations, diagnostic measurement operations, etc.) to operate. For example, the system may be configured to prevent such operation until movement of the latching mechanism indicating engagement and secure attachment between modules is detected, and then, upon detection of latching movement, the system may responsively enable such operation.

[0068] Figures 15A-15C A perspective view of a latching mechanism 410 of a modular patient care system 400 according to some embodiments is shown. In the depicted example, the latching mechanism 410 allows for mechanical connection between functional modules 450. By engaging the latching mechanism 410, a functional module 450 can be mechanically coupled to another functional module 450 or another component of the patient care system 400.

[0069] In addition to allowing the functional module 450 to be mechanically coupled and decoupled, the latching mechanism 410 also allows the electrical connector 420 to be properly engaged and disengaged as needed. Thus, by engaging the latching mechanism 410, the functional module 450 can be mechanically and electrically coupled to another component of the patient care system 400.

[0070] refer to Figure 15B During operation, the latch mechanism 410 can be rotated relative to the module body 452 to move the latch body 412 between an unlocked position and a locked position. In the depicted example, the latch body 412 can be in the unlocked position to allow the functional module 450 to disengage or be released from another component of the patient care system 400. It is understood that the electrical connector 420 of the functional module 450 can also be electrically disconnected in the unlocked position.

[0071] During operation, the latching mechanism 410 can rotate relative to the module body 452 to move the latch body 412 to a locked position. In the depicted example, the latch body 412 can move clockwise or upward toward the module body 452 to move the latching mechanism to the locked position. In some embodiments, the latch body 412 may include a hook-shaped protrusion 414 extending from the latch body 412 to allow the latch body 412 to actively engage with the complementary functional module 450 or other components of the patient care system 400. In some embodiments, the hook-shaped protrusion 414 may engage in a complementary recess or groove of a mating component. Optionally, the hook-shaped protrusion 414 may have a resilient configuration.

[0072] refer to Figure 15C During operation, the latch mechanism 410 can be translated relative to the module body 452 to move the latch body 412 between unlocked and locked positions. In the depicted example, the latch body 412 can be in the unlocked position to allow rotation of the latch body 412 as described above. In some embodiments, the latch body 412 is moved inward relative to the module body 452 to the unlocked position. In some embodiments, an ejector mechanism on the module body 452 is pressed to move the latch body 412 to the unlocked position.

[0073] In some embodiments, when the ejection mechanism is released, the latch body 412 may translate to a locked position. Optionally, the latch body 412 may be spring-loaded or biased to the locked position. In the locked position, the latch body 412 may prevent rotation of the latch mechanism 410, thereby preventing the functional module 450 from accidentally engaging or disengaging within the patient care system 400.

[0074] In some embodiments, the latching mechanism 410 may include a latching sensor 430 to detect movement of the latching body 412 relative to the module body 452. In the depicted example, the latching sensor 430 may be disposed on or within a latching extension 416 disposed within the module body 452. During operation, the latching sensor 430 may move with the latching body 410 as the latching body 412 rotates and / or translates as described above. In some embodiments, the latching sensor 430 may be fixed within the module body 452 and sense movement of the latching body 412.

[0075] In some embodiments, the latch sensor 430 may be a Hall effect sensor, an optical interruption sensor, a capacitive sensor, and / or an inductive sensor. Optionally, the latch sensor 430 may withstand or resist fluid ingress. In some embodiments, the latch sensor 430 may be unidirectional and may detect rotation or translation of the latch body 412. In some embodiments, the latch sensor 430 is omnidirectional and may detect rotation and translation of the latch 412. Optionally, the latch body 412 may include a magnet adhered, attached, or encased therein to allow the latch sensor 430 to detect rotation and / or translation of the latch body 412.

[0076] In the illustrated example, latch sensor 430 can detect translation of latch body 412, such as when the ejector mechanism translates latch body 412. By detecting the movement of latch mechanism 410, latch sensor 430 can be used to determine the user's intent, such as when the user intends to connect or disconnect functional module 450.

[0077] Upon detecting an unlocking event, function module 450 can record the event and shut off the power to electrical connector 420 to prevent arcing and corrosion. By sensing the position of latch body 412, function module 450 can ensure that no electrical signal is sent to electrical connector 420 when function module 450 unlocks.

[0078] Similarly, latch sensor 430 can be used to detect rotation of latch body 412, such as when latch mechanism 410 engages with receiving function module 450. By detecting rotational movement of latch mechanism 410, latch sensor 430 determines whether latch body 412 is engaged or disengaged from complementary function module.

[0079] Therefore, during operation, the latch sensor 430 can be used to determine when to make an electrical connection to the electrical connector 420 and when to safely make a mechanical connection at the latch mechanism 410 between adjacent modules. Based on this determination, power can be turned on in a controlled manner, and intra-module communication can be initiated.

[0080] Figure 16 This is an exploded perspective view of an electrical connector 520 for a patient care system module according to some embodiments. In the depicted example, a radial seal 530 can protect the electrical connector 520 from liquids (such as cleaning chemicals) that could damage the structure of the electrical connector 520 or affect the electrical connection provided by the electrical connector 520.

[0081] In some embodiments, the radial seal 530 is a resilient seal covering the electrical connector 520 to protect the electrical connector 520 from liquids such as cleaning chemicals. The radial seal 530 can be formed of any resilient material or any other elastic material. In some embodiments, the radial seal 530 can be a polyurethane casting or overlay. The radial seal 530 can include a seal body 532 for generally covering the connector face 522 of the electrical connector. Optionally, the radial seal 530 can extend onto the connector edge 526. As shown, the seal edge 536 of the seal body 532 can extend and engage with the connector edge 526. Optionally, the seal edge 536 and / or the connector edge 526 can allow the mating connector to align with the electrical connector 520. In some embodiments, the seal 530 can be an axial seal.

[0082] It is understood that the radial seal 530 may include a hole 534 to facilitate mechanical and electrical connection with connector pins 524 extending from the connector face 522. Optionally, the various connector pins 524 may have different or staggered heights. By staggering the heights of the connector pins 524, the connection sequence of the connector pins 524 can be controlled. For example, the longest pin 524 may contact the mating connector before the shorter connector pins 524. Similarly, during disconnection, the shorter connector pins 524 may be disconnected before the longer connector pins 524 disconnect. By changing the heights of the connector pins 524, certain functions or connections can be activated during connection or remain active until the disconnection ends.

[0083] In some embodiments, connector pin 524 may be cantilevered to be pushed or biased to a return or rest position.

[0084] Figure 17 This is a top view of an electrical connector 620 for a module of a patient care system according to some embodiments. Similar to electrical connector 520, radial seal 630 can protect electrical connector 620 from liquids (such as cleaning chemicals) that can damage the structure of electrical connector 620 or affect the electrical connection provided by electrical connector 620.

[0085] In some embodiments, the radial seal 630 is an elastic seal covering the electrical connector 620 to protect the electrical connector 620 from liquids such as cleaning chemicals. The radial seal 630 can be formed of any elastic material, such as a thermoplastic elastomer or any other elastic material. In some cases, the radial seal 630 can extend onto the outer diameter of the electrical connector 620. In some embodiments, the radial seal 630 can be adhesively or otherwise mechanically interlocked to the substrate of the electrical connector 620. It is understood that the radial seal 630 can hold portions of the electrical connector 620 in place. Advantageously, the radial seal 630 can prevent the electrical connector 620 from peeling or separating.

[0086] It is understood that the radial seal 630 may include an aperture 634 to facilitate mechanical and electrical connection with a connector pin 624 extending from the electrical connector 620. In some embodiments, the aperture 634 may be reduced in size to prevent mold overflow from covering the connector pin 624.

[0087] Figure 18 yes Figure 17 Bottom view of the electrical connector 620. Figure 19 yes Figure 17 Cross-sectional view of electrical connector 620. Figure 20 yes Figure 17 A cross-sectional perspective view of the electrical connector 620. Figure 21 yes Figure 17 Detailed cross-sectional view of electrical connector 620. (Reference) Figure 17 -21, Connector pin 624 can be fixed inside electrical connector 620.

[0088] In the depicted example, the radial seal 630 may abut a feature of the connector pin 624 to retain the connector pin 624 within the radial seal 630 and the electrical connector 620 to prevent pull-out of the connector pin 624. For example, an upper contact 642 and a lower contact 644 may each extend radially from a stud 646 of the connector pin 624 to engage with the radial seal 630. In some embodiments, the upper contact 642 and the lower contact 644 may be spaced apart to capture a portion of the radial seal 630 therebetween, thereby retaining the connector pin 624 within the radial seal 630. Optionally, the upper contact 642 and / or the lower contact 644 may be larger than a corresponding hole 634 in the radial seal 630 to prevent pull-out of the connector pin 624. In some embodiments, the lower contact 644 may be larger than the upper contact 642.

[0089] It is understood that connector pin 624 can be inserted into radial seal 630 from the inner surface of radial seal 630. In some embodiments, hole 634 can be elastically stretched to allow upper contact head 642 to pass through hole 634.

[0090] In the depicted example, when connector pin 624 mechanically engages with the mating connector, upper contact head 642 is displaced to move stud 646 downwards, bringing it into contact with contact spring 648 to allow electrical signals to be transmitted from connector pin 624 into the device. In some embodiments, spring holder 625 may include compression stop 623 to limit downward movement or compression of connector pin 624 to prevent damage to electrical connector 620. Compression stop 623 may be molded into spring holder 625. In some embodiments, spring holder 625 may be supported by a housing of the functional module.

[0091] It is understood that connector pin 624 can be biased upwards or pushed to separate stud 646 from contact spring 648. For example, bias spring 643 can bias or push connector pin 624 upwards away from contact spring 648. Bias spring 643 can engage with lower contact head 644. When connector pin 624 engages with mating connector, bias spring 643 can be compressed.

[0092] The various connector pins 624 can have different or staggered heights. In some embodiments, the length of the stud 646 of each connector pin 624 can be varied to adjust the height of the connector pin 624. By staggering the heights of the connector pins 624, the connection sequence of the connector pins 624 can be controlled. For example, the longest pin 624 can contact the mating connector before the shorter connector pins 624. Similarly, during disconnection, the shorter connector pin 624 can be disconnected before the longer connector pin 624 disconnects. By changing the height of the connector pins 524, certain functions or connections can be activated during connection or remain activated until the disconnection ends.

[0093] It is understandable that the connecting pin 624, bias spring, contact spring 648, and PCB pad can be formed or coated with conductive materials such as copper, nickel, and / or gold.

[0094] Figure 22This is a detailed cross-sectional perspective view of an electrical connector 720 for a patient care system module according to some embodiments. In the depicted example, the electrical connector 720 may include connector pins 724 that lock into place to prevent removal of electrical contact. In some embodiments, connector pins 724 may include a barbed interface 747 at the lower portion of a stud 746. When connector pins 724 are displaced or lowered, the barbed interface 747 of the stud 746 may engage with a contact spring 748 to bend and displace the contact spring 748, thereby locking connector pins 724 in the contacted or lowered position. As shown, the barbed interface 747 may extend radially from the stud 746 and may include a conical shape.

[0095] Figure 23 This is a detailed cross-sectional perspective view of an electrical connector 820 for a patient care system module according to some embodiments. As described above, a contact spring 848 facilitates electrical contact from connector pin 824 to the PCB 850 of the functional module.

[0096] In the rest position, connector pin 824 and contact spring 848 are spaced apart from PCB 850 and PCB pad 852. There is no electrical connection between connector pin 824 and PCB 850 in the rest position. In some embodiments, contact spring 848 deflects or pushes connector pin 824 upwards away from PCB 850.

[0097] When engaged with a mating connector, connector pin 824 can be moved or otherwise moved downwards. By moving connector pin 824 downwards, contact spring 848 can move downwards to engage with PCB pad 852 of PCB 850, thereby facilitating an electrical connection between the contact head of connector pin 824 and the PCB 850 of the module. In some embodiments, the compliance of contact spring 848 can be configured to allow contact with the desired engagement force without damaging PCB pad 852. In some embodiments, contact spring 848 may have a reduced thickness compared to a conventional contact spring, thereby providing a reduced spring or bias force.

[0098] In some embodiments, the contact spring 848 may include dual contact points at the PCB contact portion 847 and / or the spring holder contact portion 849. Advantageously, by providing dual (or multiple) contact points, the contact spring 848 can provide reliable contact and contamination tolerance.

[0099] Figure 24This is a perspective view of an electrical connector 920 for a module of a patient care system according to some embodiments. In the depicted example, the electrical connector 920 includes a plurality of connector coils 924 arranged along a connector face 922. The connector coils 924 can be configured to meshed engagement with mating connector coils. Advantageously, by providing engagement, the connector coils 924 can have a larger surface contact, thereby improving the current capacity, expected life, and vibration tolerance of the electrical connector 920.

[0100] In the depicted example, the connector coil 924 is arranged to extend radially away from the connector face 922. In some embodiments, the connector coil 924 is fixed in circumferential contact with the connector face 922. In some embodiments, the connector coil 924 extends radially through the connector face 922.

[0101] In some embodiments, the connector coil 924 is wound with wire. The wire may be wound with a spacing that allows the connector coil 924 to overlap and conduct electricity, permitting mating. The spacing of the connector coil 924 may be configured to provide sufficient mating force. It is understood that the wire diameter, length, and shape of the connector coil 924 may be configured for various applications. In some embodiments, the connector coil 924 may include a conductive plating. The electrical connector 920 may include a resilient cover that may partially cover and / or retain the connector coil 924.

[0102] Figure 25 These are multiple cross-sectional views of an electrical connector 1020 for a module of a patient care system according to some embodiments. In the depicted examples, the electrical connector 1020 can be configured to control the connection and disconnection sequence of various circuits terminated by the electrical connector 1020. It will be understood that the electrical connectors described herein can be configured in a similar manner.

[0103] In some embodiments, various connector pins 1024a, 1024b, 1024c, 1024d may engage with corresponding contact springs 1048a, 1048b, 1048c, 1048d. In the depicted example, contact springs 1048a, 1048b, 1048c, 1048d may have different or staggered heights relative to the corresponding connector pins 1024a, 1024b, 1024c, 1024d. By staggering the heights of contact springs 1048a, 1048b, 1048c, 1048d, the connection sequence of connector pins 1024a, 1024b, 1024c, 1024d can be controlled. For example, the tallest contact spring 1048c may contact the corresponding connector pin 1024c before a shorter contact spring and connector pin. Similarly, during disconnection, the shorter contact spring 1048a can be disconnected before the taller contact spring 1048c is disconnected. By changing the heights of the contact springs 1048a, 1048b, 1048c, and 1048d, certain functions or connections can be activated during connection or remain active until the disconnection ends.

[0104] For example, the highest contact spring 1048c can be coupled to the ground channel, the second highest contact spring 1048b can be coupled to the power channel, the second highest contact spring 1048d can be coupled to the CAN channel, and the shortest contact spring 1048a can be coupled to the module channel. Therefore, as shown, during connection, the ground channel connector pin 1024c can be electrically connected first, the power channel connector pin 1024b can be coupled subsequently, the CAN channel connector pin 1024d can be coupled subsequently, and the module channel connector pin 1024a can be coupled last. Similarly, during disconnection, the channels can be disconnected in the reverse order.

[0105] In some embodiments, the various connector pins 1024a, 1024b, 1024c, and 1024d may have different or staggered heights. In some embodiments, the lengths of the studs 1046a, 1046b, 1046c, and 1046d for each connector pin 1024a, 1024b, 1024c, and 1024d may be varied to adjust the height of the connector pins 1024a, 1024b, 1024c, and 1024d, thereby controlling the connection sequence of each channel.
