[0001] This application relates to the field of medical device technology, specifically to a printer module and a patient monitor. Background Technology

[0002] In related technologies, patient monitors include thermal printers, which are used to record physiological data measured by the monitor onto thermal paper. Currently, to save internal space in the monitor, the printer is located in a slot within a module box, which is typically connected to the monitor via a cable. To meet the monitor's safety standards, the printer's circuit board must be grounded. The usual practice is to install a grounding wire inside the printer; however, this grounding wire occupies internal space and increases costs. Utility Model Content

[0041] Please refer to Figures 1 to 5 This application provides a printer module 100 for use in a monitor. The printer module 100 includes a housing 12, a printer host 14, a grounding bracket 16, and an adapter plate 18. The housing 12 has a first receiving cavity 20. The printer host 14 includes a circuit board 22, which is disposed within the first receiving cavity 20. The circuit board 22 has a first interface 24 and a first grounding portion 26. The grounding bracket 16 is disposed within the first receiving cavity 20. The adapter plate 18 is disposed within the first receiving cavity 20. The adapter plate 18 has a second interface 28 and a second grounding portion 30. The first interface 24 is electrically connected to the second interface 28. The printer host 14 and the adapter plate 18 are both fixedly connected to the grounding bracket 16, and the first grounding portion 26 is electrically connected to the second grounding portion 30 through the grounding bracket 16. The second interface 28 is used to connect to a third interface on a plug-in box.

[0042] In the printer module 100 described above, the printer host 14 and the adapter board 18 are both fixedly connected to the grounding bracket 16, and the first grounding part 26 is electrically connected to the second grounding part 30 through the grounding bracket 16. Thus, the grounding bracket 16 has both installation and grounding functions, which can reduce the use of grounding wires, save internal space of the printer module 100 to a certain extent, and reduce costs.

[0043] Specifically, a patient monitor is a medical device that can monitor various physiological parameters of the human body in real time and compare them with known set values. Physiological parameters include, but are not limited to, electrocardiogram (ECG) signals, heart rate, blood oxygen saturation, blood pressure, respiratory rate, and body temperature. A patient monitor may include a monitoring unit capable of monitoring various physiological parameters and a plug-in box detachably connected to the monitoring unit. The monitoring unit may include a display screen for displaying the monitored physiological parameters.

[0044] In one embodiment, the monitor includes a plug-in box, and a monitoring host can be electrically connected to the plug-in box to jointly monitor various physiological parameters of the human body. The monitoring host can be electrically connected to a built-in battery or an external power source to operate. The monitoring data acquired by the monitoring host and / or the plug-in box can be displayed on a screen.

[0045] An extension box, also called an auxiliary box or expansion box, is an external enclosure that can be connected to a monitoring host. The extension box has module slots for accommodating one or more pluggable modules, allowing the modules to be replaced. The modules are connected to the monitoring host via cables from the extension box.

[0046] In one embodiment, the monitoring host has a module slot in which plug-in modules are pluggable and replaceable. Plug-in modules include, but are not limited to, parameter measurement modules, printer module 100, etc. Optionally, the module slot may also be referred to as a plug-in slot.

[0047] In some embodiments, the parameter measurement module may be at least one of the following: an electroencephalogram (EEG) monitoring module, a non-invasive continuous cardiac output monitoring module, an anesthetic gas monitoring module, an anesthesia depth monitoring module, an invasive blood pressure monitoring module, a blood oxygen monitoring module, and an end-tidal carbon dioxide monitoring module.

[0048] Understandably, a patient monitor may contain one or more parameter measurement modules. The monitoring functions of these modules may differ. Parameter measurement modules can be selected based on actual needs. Understandably, both the plug-in modules and the plug-in box support hot-swapping, allowing for flexible combination and facilitating use, upgrades, and maintenance.

[0049] The printer module 100, also known as the recorder module, is a detachable plug-in module installed in the plug-in box. Unlike traditional printers that are integrated into the monitoring host, the printer module 100 further detaches the printer, eliminating the need for a built-in printer in the monitoring host and thus reducing its size.

[0050] The housing 12 protects the components of the printer module 100 and provides a mounting platform. The housing 12 is made of materials including, but not limited to, plastic and metal. The first receiving cavity 20 provided in the housing 12 provides space for accommodating the components of the printer module 100.

[0051] The printer module 100 may include a printer host 14, which primarily performs printing functions. Optionally, the printer host 14 may be a thermal printer used to record waveforms or physiological parameters measured by the monitor.

[0052] The circuit board 22 of the printer host 14 is housed within the first receiving cavity 20, allowing the circuit board 22 to be protected by the outer casing 12 and preventing it from being damaged by moisture. The circuit board 22 has a first interface 24 and a first grounding portion 26. The first interface 24 enables power supply and / or signal transmission for the printer host 14. The first grounding portion 26 is used for grounding the circuit board 22.

[0053] The adapter plate 18 is disposed within the first receiving cavity 20, allowing it to be protected by the outer casing 12 to prevent moisture damage. The adapter plate 18 has a second interface 28 and a second grounding portion 30. The second interface 28 is electrically connected to the first interface 24. Optionally, in one embodiment, the second interface 28 is used to connect to a third interface within a module slot of the plug-in box, thereby electrically connecting the first interface 24 to the third interface. Optionally, in one embodiment, the second interface 28 is used to connect to a fourth interface within a module slot of the monitoring host, thereby electrically connecting the first interface 24 to the fourth interface.

[0054] The second interface 28 can also provide power supply, signal transmission, and grounding functions. When the second interface 28 is connected to the third or fourth interface, the monitoring host can supply power, transmit data, and ground to the printer module 100 through the third or fourth interface, the second interface 28, and the first interface 24.

[0055] The grounding bracket 16 is disposed within the first receiving cavity 20, allowing it to be protected by the outer casing 12 and preventing moisture damage. On one hand, the first grounding part 26 is electrically connected to the second grounding part 30 via the grounding bracket 16, enabling the grounding parts of the printer host 14 and the adapter board 18 to be electrically connected. The grounding bracket 16 serves to connect the two grounding parts. The second grounding part can be connected to the grounding structure of the monitoring host, thus allowing the printer module 100 to be connected to the grounding structure of the monitoring host when it is inserted into the module slot of the plug-in box or the module slot of the monitoring host. On the other hand, both the printer host 14 and the adapter board 18 are fixedly connected to the grounding bracket 16, providing a mounting platform for them and allowing them to be fixed to the outer casing 12. The grounding bracket 16 can also be fixed to the inner wall of the outer casing 12. In summary, the grounding bracket 16 has both installation and grounding functions, which can reduce the use of grounding wires, save internal space of the printer module 100 and reduce costs to a certain extent.

[0056] In some implementations, please refer to Figures 1 to 5The front side of the first receiving cavity 20 has a first opening 32. The printer host 14 is assembled to the housing 12 through the first opening 32. The housing 12 includes a rear side plate 34 disposed opposite to the first opening 32. The grounding bracket 16 is located between the printer host 14 and the rear side plate 34. The rear side plate 34 is provided with a through hole 36 communicating with the first receiving cavity 20. The through hole 36 exposes the second interface 28.

[0057] This facilitates the assembly and disassembly of the printer module 100.

[0058] Specifically, the front side of the first receiving cavity 20 has a first opening 32. During assembly, the printer host 14 and the adapter plate 18 can be assembled onto the grounding bracket 16 outside the housing 12 to form a whole, so that the first interface 24 is electrically connected to the second interface 28, and the first grounding part 26 is electrically connected to the second grounding part 30 through the grounding bracket 16. Then, the entire assembly can be inserted into the first receiving cavity 20 through the first opening 32. The adapter plate 18 and the grounding bracket 16 are located inside the first receiving cavity 20, with a portion of the printer host 14 located inside the first receiving cavity 20 and another portion protruding from the housing 12 through the first opening 32. The portion of the printer host 14 located inside the first receiving cavity 20 may include a circuit board 22. The grounding bracket 16 is fixed to the outside of the rear side plate 34 or other side plates of the housing 12 using screws, thereby securing the entire assembly.

[0059] During disassembly, the screws on the rear side panel 34 or other side panels of the outer casing 12 can be loosened to separate the entire assembly from the outer casing 12, and then the assembly can be pulled out through the first opening 32. Afterwards, the assembly can be further disassembled to obtain the separate printer host 14, adapter plate 18, and grounding bracket 16.

[0060] The printer host 14 and the adapter board 18 can be fixedly connected to the grounding bracket 16 by means including but not limited to screws, clips, etc.

[0061] The through-hole 36 allows a third or fourth interface to be inserted into and connected to the second interface 28. Optionally, the third or fourth interface may include one of a female and a male connector, and the second interface 28 may include the other of a female and a male connector. The printer module 100 is inserted into the module slot of the plug-in box or the module slot of the monitoring host, with the female and male connectors plugged in to enable the monitoring host to supply power to the printer module 100, enabling the printer module 100 to transmit data with the monitoring host and to ground.

[0062] In some implementations, please refer to Figures 3 to 5The grounding bracket 16 includes a first grounding plate 38 and a second grounding plate 40 that are opposite to and spaced apart. The first grounding plate 38 and the second grounding plate 40 are electrically connected. The first grounding plate 38 and the second grounding plate 40 are sequentially disposed between the printer host 14 and the rear panel 34. The first grounding part 26 is sequentially electrically connected to the grounding pin of the second interface 28 through the first grounding plate 38, the second grounding plate 40 and the second grounding part 30.

[0063] Therefore, the first grounding part 26 can be electrically connected to the sweep pin of the second interface 28.

[0064] Specifically, in Figure 5 In the illustrated embodiment, the grounding bracket 16 is frame-shaped, with the first grounding plate 38 serving as the front grounding plate and the second grounding plate 40 serving as the rear grounding plate. The first grounding plate 38 and the second grounding plate 40 are connected by two connecting plates 44, which are arranged side-by-side between the first grounding plate 38 and the second grounding plate 40, thereby electrically connecting the first grounding plate 38 and the second grounding plate 40. In a front-to-back direction, the printer module 100, the first grounding plate 38, the second grounding plate 40, and the adapter plate 18 are arranged sequentially.

[0065] The first grounding part 26 is electrically connected to the grounding pin of the second interface 28 via the first grounding plate 38, the second grounding plate 40, and the second grounding part 30, thereby enabling the printer module 100 and the adapter board 18 to be electrically connected to the grounding pin of the second interface 28. When the printer module 100 is inserted into the module slot of the plug-in box or the module slot of the monitoring host, the printer module 100 can be electrically connected to the grounding structure on the monitoring host via the adapter board 18, the grounding pin of the second interface 28, and the third interface of the plug-in box or the fourth interface of the monitoring host, thereby achieving grounding of the printer module 100 and the adapter board 18, which meets safety standards.

[0066] Furthermore, the second interface 28 also includes power supply pins and signal pins. The second interface 28 is an interface that integrates ground pins, power supply pins and signal pins, thereby saving space.

[0067] In some implementations, please refer to Figure 5 The printer module 100 includes a conductive element 46, and the first grounding part 26 is electrically connected to the first grounding plate 38 through the conductive element 46.

[0068] This allows for an electrical connection between the first grounding part 26 and the first grounding plate 38.

[0069] Optionally, one end of the conductive element 46 can directly contact the first grounding portion 26, and the other end can directly or indirectly contact the first grounding plate 38 to achieve electrical connection. Indirect contact includes, but is not limited to, indirect contact with the first grounding plate 38 via screws. Alternatively, one end of the conductive element 46 can be fixedly connected to the first grounding plate 38 via screws. Optionally, one end of the conductive element 46 can also indirectly contact the first grounding portion 26. Optionally, the conductive element 46 can be a conductive spring, thereby adapting to the distance between the printer host 14 and the first grounding plate 38.

[0070] In some implementations, please refer to Figure 4 The printer host 14 is fixedly connected to the first grounding plate 38, and the adapter plate 18 is fixedly connected to the second grounding plate 40. This reduces the number of connecting components and lowers costs. Specifically, the first grounding plate 38 and the second grounding plate 40 are sequentially positioned between the printer host 14 and the rear panel 34. Therefore, the printer host 14 is closer to the first grounding plate 38, and the adapter plate 18 is closer to the second grounding plate 40. The fixed connection of the printer host 14 to the first grounding plate 38 and the adapter plate 18 to the second grounding plate 40 results in shorter lengths of the connecting components (such as connecting wires or conductive parts 46) connecting the first grounding part 26 to the first grounding plate 38 and the connecting components connecting the second grounding part 30 to the second grounding plate 40. This reduces the number of connecting components, lowers costs, and saves internal space in the printer module 100.

[0071] exist Figure 4 In the embodiment shown, the printer host 14 is fixedly connected to the front side of the first ground plate 38, and the adapter plate 18 is fixedly connected to the rear side of the second ground plate 40. Thus, it is convenient to fix the printer host 14 on the first ground plate 38 and to fix the adapter plate 18 on the second ground plate 40.

[0072] In some implementations, please refer to Figure 5 The first grounding plate 38 and the second grounding plate 40 are integrated into one unit. This improves the structural strength of the grounding bracket 16 and reduces assembly steps. Specifically, the integrated structure of the first grounding plate 38 and the second grounding plate 40 reduces or eliminates gaps formed by their connection, thereby improving the structural strength of the grounding bracket 16. It also reduces the assembly steps required for connecting the first grounding plate 38 and the second grounding plate 40, improving the assembly efficiency of the printer module 100.

[0073] Optionally, in Figure 5In the illustrated embodiment, the grounding bracket 16 is frame-shaped. The frame-shaped grounding bracket 16 can be formed by bending a flat metal plate three times. Of the two opposing side plates, one can be selected as the first grounding plate 38, and the other as the second grounding plate 40. Another pair of opposing side plates form a connecting plate 44.

[0074] In some implementations, please refer to Figure 4 and Figure 5 The second interface 28 is covered with a protective sleeve 48, and the through hole 36 exposes the second interface 28 and the protective sleeve 48. This protects the second interface 28 and extends its service life. Specifically, the second interface 28 is used to connect to the third interface of the plug-in box through the through hole 36. The protective sleeve 48 protects the pins of the second interface 28, preventing them from bending or breaking during the insertion of the second interface 28 and the third interface. Furthermore, the protective sleeve 48 also cushions the impact force from the third interface during insertion, thus protecting the second interface 28.

[0075] Alternatively, the protective case 48 may be a silicone protective case 48 or a rubber protective case 48.

[0076] In some implementations, please refer to Figure 5 The grounding bracket 16 is provided with a clearance hole 50. The first interface 24 and the second interface 28 are electrically connected via a connecting wire (not shown), which passes through the clearance hole 50. This makes the internal space of the housing 12 neater. Specifically, the first interface 24 and the second interface 28 can be electrically connected via a connecting wire. The connecting wire can perform functions including but not limited to power supply and signal transmission. By passing the connecting wire through the clearance hole 50 of the grounding bracket 16 to connect the first interface 24 and the second interface 28, the connecting wire does not need to bypass the grounding bracket 16 to connect the first interface 24 and the second interface 28, avoiding the mess of connecting wires and making the internal space of the housing 12 neater. Moreover, the wiring of the connecting wire inside the grounding bracket 16 can also improve the utilization rate of the internal space of the housing 12.

[0077] In some implementations, please refer to Figures 3 to 6 The printer module 100 includes a support shell 52, at least a portion of which is located in a first receiving cavity 20. The support shell 52 is provided with a second receiving cavity 54. The front side of the second receiving cavity 54 has a second opening 56. The circuit board 22 of the printer host 14 is located in the second receiving cavity 54. The operation panel 58 of the printer host 14 and the cover of the printing paper tray 60 are exposed through the second opening 56.

[0078] This allows for the fixation of the printer host 14 and the isolation between the circuit board 22 and the grounding bracket 16 on the printer host 14, thereby avoiding unnecessary contact between the circuit board 22 and the grounding bracket 16.

[0079] Specifically, the support shell 52 can be assembled to the outer shell 12 through the first opening 32. Figure 4 In the illustrated embodiment, a portion of the support housing 52 is located within the first receiving cavity 20. The printer host 14 is fitted onto the support housing 52 through the second opening 56, and the circuit board 22 of the printer host 14 is located within the second receiving cavity 54, thereby the support housing 52 can separate the circuit board 22 and the grounding bracket 16.

[0080] Optionally, the support housing 52 includes a frame 62 and a rear cover 64, the frame 62 surrounding the sidewall of the first opening 32, and the rear cover 64 located between the printer host 14 and the grounding frame.

[0081] The control panel 58 of the printer host 14 and the cover of the paper tray 60 are exposed through the second opening 56, thereby allowing the user to conveniently operate the printer host 14, add paper, and obtain medical results from the front of the printer module 100.

[0082] The paper tray 60 is used to hold printing paper. The printer host 14 can print human physiological parameters transmitted from the monitoring host onto the printing paper. The cover of the paper tray 60 is exposed through the second opening 56, allowing the user to add printing paper and obtain medical results from the front of the printer module 100. Optionally, the printing paper includes thermal paper.

[0083] When it is necessary to add printing paper, the user can open the cover of the printing paper tray 60 from the front of the monitor, remove the roller of the original printing paper, install the new printing paper into the printing paper tray 60, and then close the cover of the printing paper tray 60.

[0084] Alternatively, in other embodiments, the printer module 100 may omit the support housing 52.

[0085] In some implementations, please refer to Figure 2 , Figures 4 to 6 The printer module 100 includes a locking structure 66, which is movably disposed on the housing 12. The locking structure 66 has a pressing part 68 and a locking hook part 70. The housing 12 is provided with a first through hole 72 and a second through hole 74. The pressing part 68 passes through the first through hole 72, and the locking hook part 70 passes through the second through hole 74. The locking hook part 70 is used to cooperate with the locking part of the plug-in box or the monitoring host to lock the printer module 100.

[0086] When the pressing part 68 is pressed, it causes the locking hook part 70 to disengage from the locking part, thereby unlocking the printer module 100.

[0087] Therefore, when the printer module 100 is inserted into the plug-in box, the printer module 100 can be effectively fixed, and the printer module 100 can be removed from the plug-in box by pressing down on the part 68.

[0088] Optionally, in Figure 2 and Figure 4 In the illustrated embodiment, the locking structure 66 is located at the bottom of the printer module 100. A latch is provided on the inner bottom wall of the module slot in the plug-in box or monitoring host. When the printer module 100 is inserted into the module slot in the plug-in box, the locking hook 70 engages with the latch of the plug-in box or monitoring host to prevent the printer module 100 from being removed from the front. The rear side of the printer module 100 is restricted by the inner rear side wall of the module slot, thereby locking the printer module 100 in the module slot of the plug-in box. At this time, a portion of the printer module 100 is located inside the module slot, and another portion protrudes outside the module slot, with the pressing part 68 located outside the module slot.

[0089] When it is necessary to remove the printer module 100, press the pressing part 68 to disengage the locking hook part 70 from the locking part, thereby unlocking the printer module 100. After unlocking, the printer module 100 can be pulled forward.

[0090] Optionally, please combine Figure 6 In one embodiment, the locking structure 66 further includes a main body 76 and an elastic element (not shown). The locking hook 70 and the pressing part 68 are provided on the main body 76. The main body 76 can be rotatably connected to the outer shell 12 through the pivots 78 on both sides. Thus, the locking structure 66 and the outer shell 12 can be movably connected through a simple structure.

[0091] In one embodiment, the locking hook portion 70 and the pressing portion 68 are located on one side of the rotation axis of the main body portion 76. On the other side of the rotation axis of the main body portion 76, a reset portion 80 is provided on the main body portion 76. An elastic member can connect the reset portion 80 and the inner wall of the outer casing 12. The elastic member provides a force to the main body portion 76 through the reset portion 80, causing the locking hook portion 70 to protrude out of the second through hole 74, and provides a force to the pressing portion 68, causing it to protrude out of the first through hole 72. Thus, the elastic member can be used to make the locking hook portion 70 cooperate with the locking portion and to make the pressing portion 68 protrude out of the first through hole 72 for user operation.

[0092] In one embodiment, when the pressing part 68 is not pressed, the locking hook part 70 can engage with the locking part, and the pressing part 68 can protrude from the first through hole 72, thereby locking the printer module 100. When the pressing part 68 is pressed, the pressing part 68 retracts into the first through hole 72 and drives the locking hook part 70 to retract into the second through hole 74, thereby unlocking the printer module 100. Thus, the printer module 100 can be unlocked by pressing the pressing part 68.

[0093] In one embodiment, when the pressing part 68 is pressed, the elastic element is compressed, storing elastic potential energy. When the pressing part 68 is released, the elastic element releases the elastic potential energy, and the pressing part 68 and the locking hook part 70 are reset by the reset part 80. Thus, the pressing part 68 and the locking hook part 70 can be reset by compressing and releasing the elastic element. Optionally, the elastic element includes a torsion spring.

[0094] Optionally, in Figure 6 In the middle, the bottom of the support shell 52 is provided with a clearance space 82, and the pressing part 68 can be located in the clearance space 82, which is conducive to the miniaturization of the printer module 100.

[0095] In some implementations, please refer to Figure 4 and Figure 5 The printer module 100 includes a cooling fan 84 disposed within a first receiving cavity 20. The outer casing 12 has ventilation holes (not shown) communicating with the first receiving cavity 20. This improves the heat dissipation efficiency of the printer module 100. Specifically, when the printer module 100 is operating, its heat-generating components (including but not limited to the printer host 14 and adapter board 18) generate heat, which can accumulate inside the outer casing 12. The outer casing 12 has ventilation holes communicating with the first receiving cavity 20, connecting the internal and external spaces of the outer casing 12. The cooling fan 84, disposed within the first receiving cavity 20, accelerates the airflow between the internal and external spaces of the outer casing 12 when operating, thereby dissipating heat from the internal space of the outer casing 12 to the external space.

[0096] Optionally, when the cooling fan 84 is working, it can draw in hot air from the interior space of the housing 12 and exhaust it to the outside of the housing 12 through the heat dissipation holes. The cooling fan 84 can be fixedly connected to the second grounding plate 40 of the grounding bracket 16. Optionally, the heat dissipation holes are formed on the rear side plate 34.

[0097] The patient monitor provided in this application includes a printer module 100 according to any of the above embodiments.

[0098] In the aforementioned monitor, both the printer host 14 and the adapter board 18 are fixedly connected to the grounding bracket 16, and the first grounding part 26 is electrically connected to the second grounding part 30 through the grounding bracket 16. Thus, the grounding bracket 16 has both installation and grounding functions, which can reduce the use of grounding wires, save internal space of the printer module 100 to a certain extent, and reduce costs.

[0099] Specifically, a patient monitor is a medical device that can monitor various physiological parameters of the human body in real time and compare them with known set values. Physiological parameters include, but are not limited to, electrocardiogram (ECG) signals, heart rate, blood oxygen saturation, blood pressure, respiratory rate, and body temperature. A patient monitor may include a monitoring unit that monitors various physiological parameters and a plug-in box that is detachably connected to the monitoring unit. The monitoring unit may include a display screen capable of displaying the monitored physiological parameters.

[0100] In one embodiment, the monitor includes a plug-in box, and a monitoring host can be electrically connected to the plug-in box to jointly monitor various physiological parameters of the human body. The monitoring host can be electrically connected to a built-in battery or an external power source to operate. Monitoring data acquired by the monitoring host and / or the plug-in box can be displayed on a screen. The plug-in box has module slots for accommodating one or more pluggable plug-in modules, allowing the plug-in modules to be replaced. The plug-in modules are connected to the monitoring host via cables from the plug-in box.

[0101] In one embodiment, the monitoring host has a module slot in which plug-in modules are pluggable, so that the plug-in modules are replaceable.
