Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a monitor body and a monitor equipped with the monitor body. Background Technology

[0002] Patient monitors are widely used medical devices in clinical practice, used to monitor patients' vital signs and physiological parameters in real time, providing crucial information for medical diagnosis and treatment planning.

[0003] like Figure 1 and Figure 2 As shown, a typical monitor 9 includes a main body 91, a functional module 92, an air pump 93, tubing, and interfaces 94, among other core components. The main body 91 comprises a rear shell 911 and a front shell 912. The rear shell 911 has a cavity for accommodating the various functional components. The front shell 912 is detachably mounted on the rear shell 911 via an adapter structure, and covers the opening of the accommodating cavity. The functional module 92, air pump 93, tubing, etc., are all fixedly assembled within the cavity of the rear shell 911. The air pump 93 is electrically connected to the functional module 92 and is driven by control commands output from the functional module 92. The tubing is sealed and connected to the output end of the air pump 93, the interface 94, and the pressure sensors, solenoid valves, and other electronic components integrated on the functional module 92, forming a complete air transmission and detection channel.

[0004] However, the existing patient monitor 9 has structural design deficiencies; for example, components such as the functional module 92, air pump 93, and tubing are arranged together in the same cavity without any partitions, and there are no physical barriers or protective structures between the functional module 92 and the air pump 93 and tubing, which makes the patient monitor 9 prone to the following risks during operation: First, if the pipeline leaks air, ages and cracks, or condensate leaks, it can easily cause the components on the functional module 92 to become damp, fail, or be damaged. Second, the electronic components on functional module 92 generate a lot of heat, which can easily raise the temperature inside the cavity, thereby accelerating the aging of the pipeline and increasing the probability of the pipeline leaking, aging and cracking, or condensate leakage. Third, the functional modules 92, air pump 93, pipelines, etc. are distributed in a messy manner, which makes it inconvenient for later inspection, maintenance and component replacement, indirectly increasing the operation and maintenance costs. Utility Model Content

[0005] To address the aforementioned issues, the primary objective of this invention is to provide a monitor body with an optimized structural layout that reduces the risk of moisture-induced failure and damage to electronic components on functional modules, while also slowing down the aging of pipelines.

[0006] The second objective of this utility model is to provide a monitor with the aforementioned monitor body.

[0007] To achieve the first objective of this utility model, this utility model provides a monitor body, including a rear shell and a front shell. The rear shell has a receiving cavity, and the front shell is connected to the rear shell and seals the opening of the receiving cavity. The monitor body also includes a partition, which is installed in the receiving cavity and divides the receiving cavity into an electrical cavity and an air passage cavity. The air passage cavity is located below the electrical cavity, and the partition has an air pump mounting position and a pipeline mounting position formed on the side of the air passage cavity.

[0008] As can be seen from the above, the separator effectively separates the functional modules and pneumatic circuit structure within the monitor body, reducing mutual interference between them and ensuring that the raw physiological signals collected by the functional modules are not distorted, thus guaranteeing measurement accuracy. Furthermore, placing the pneumatic circuit chamber below the electrical chamber prevents liquid or gas from entering the electrical chamber even if there is a leak (such as gas or condensate), preventing short circuits and corrosion of the functional modules, reducing equipment failures and safety hazards. It also prevents the heat generated by the functional modules during operation from directly affecting the pneumatic components, avoiding performance fluctuations due to abnormal temperatures, slowing down pipe aging, improving safety, and reducing the risk of failure. Moreover, the separator has pre-set installation positions for the air pump and pipes, enabling standardized component positioning. This eliminates the need for repeated adjustments during assembly, improving assembly efficiency and facilitating subsequent maintenance without disassembling unrelated components, preventing secondary damage and reducing maintenance difficulty.

[0009] A further option is to include a heat sink on the monitor body, which is mounted on the partition and located on the electrical cavity side.

[0010] As can be seen from the above, the heat sink can improve the heat dissipation effect of the functional modules, provide more stable support for the functional modules, and give the partition more structural design freedom, thereby improving the functionality and practicality of the partition, and reducing the structural complexity of the back shell and the assembly difficulty of each component.

[0011] A preferred embodiment is that the separator has a receiving position formed on the electrical cavity side, and the heat sink covers the receiving position and surrounds the receiving position to form a battery compartment.

[0012] As can be seen from the above, setting a receiving position for accommodating the battery on the separator simplifies the structure of the back cover, facilitates the manufacturing of the back cover and separator, and makes better use of the space inside the receiving cavity, which helps to miniaturize the monitor body. It also facilitates the assembly of the battery with the monitor body. Furthermore, covering the heat sink with the receiving position allows the heat sink to simultaneously dissipate heat from the battery, extending the battery's lifespan and ensuring the stability of battery charging and discharging as well as its safety during use.

[0013] A further proposed solution is that, in the first direction, the hatch of the battery compartment is formed at the first end of the partition; the rear shell is provided with an insertion port that penetrates the wall of the rear shell in the first direction and faces the hatch; the monitor body also includes a cover that is detachably connected to the rear shell and can seal the hatch.

[0014] As can be seen from the above, this design makes the battery replaceable, so that when the monitor with this monitor body is battery powered, the monitor's battery life can be increased by replacing the battery, and it also facilitates battery maintenance and replacement.

[0015] A further proposed solution is that the pipe installation positions and air pump installation positions are distributed along the first direction; the receiving positions and air pump installation positions are distributed along the second direction, and the normals of the second direction, the first direction, and the mounting plate of the heat sink are mutually perpendicular.

[0016] As can be seen from the above, this design can make full use of the space inside the cavity, reduce the space occupied by the partition, air pump, tubing and battery, etc., and help to miniaturize the monitor body.

[0017] Another preferred embodiment is that the separator has a first support portion and a second support portion formed on the electrical cavity side. The top of the first support portion is provided with a first connecting hole, and the second support portion is provided with a slot. The bottom of the slot is at the same height as the top of the first support portion. The heat sink is provided with a mounting plate. The mounting plate is provided with a clearance position at the first support portion and the second support portion. The clearance position penetrates the mounting plate in the normal direction of the mounting plate.

[0018] As can be seen from the above, since the separator is generally made of non-metallic materials and the heat sink is made of metallic materials, by setting a first support part and a second support part on it to support the parameter processing board of the functional module, and setting a clearance position on the heat sink to allow the parameter processing board to pass, the interference suffered by the parameter processing board when collecting various parameter signals can be reduced.

[0019] Another preferred embodiment is that the separator has a stop, a pin, and a second connecting hole formed on the electrical cavity side. The stop includes a vertical part and a horizontal part, with the vertical part connecting the body of the separator and the horizontal part in an L-shape. The mounting plate of the heat sink has a strip groove and a first through hole, which penetrate the mounting plate in the normal direction. The extension direction of the strip groove is parallel to the extension direction of the horizontal part. The mounting plate is engaged with the stop, the pin is located in the strip groove, and the first through hole is aligned with the second connecting hole.

[0020] As can be seen from the above, this design facilitates the disassembly and assembly of the partition and the heat sink, simplifies the assembly steps, and improves assembly efficiency.

[0021] Another preferred embodiment is that the partition is also formed with a tongue and a connecting ear, the tongue is located on the side of the partition, the connecting ear is located at the bottom of the partition, and the connecting ear is provided with a second through hole; the rear shell is formed with a plug part at the tongue, the plug part is engaged with the tongue, the rear shell is provided with a slot at the connecting ear, the slot is provided with a third connecting hole, the connecting ear is inserted into the slot, and the second through hole is aligned with the third connecting hole.

[0022] As can be seen from the above, this design makes it easier to assemble and disassemble the partition and the rear shell, simplifies the assembly steps, improves assembly efficiency, and enhances the convenience of maintenance and repair.

[0023] A further proposed solution is that the partition is made of plastic material; the rear shell is also provided with a first heat dissipation hole group and a second heat dissipation hole group, with the first heat dissipation hole group located in the electrical cavity and the second heat dissipation hole group located in the air passage cavity.

[0024] As can be seen from the above, using plastic materials to make the partitions can reduce the difficulty of manufacturing the partitions and allow the partitions to be molded into complex structures for assembly with various components (such as functional modules, air pumps, pipelines, heat sinks, etc.); the design of the heat dissipation hole group can assist the functional modules, air pumps, etc. in heat dissipation, improve the stability of the functional modules, air pumps, etc. and extend their service life.

[0025] To achieve the second objective of this utility model, this utility model provides a monitor, including a functional module, an air pump, pipelines, and an interface. The air pump is electrically connected to the functional module, and the pipelines are respectively connected to the output end of the air pump, the interface, and the pressure sensor of the functional module. The monitor also includes the monitor body described above. The functional module is located in the electrical cavity, the air pump and pipelines are located in the air passage cavity, and the interface is installed on the rear shell.

[0026] As can be seen from the above, a monitor with the aforementioned monitor body can improve the stability and reliability of its operation, optimize the layout of various components, reduce the risk of moisture-induced failure and damage to electronic components on functional modules, and slow down the aging of pipelines.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0037] Patient monitor examples Reference Figure 3 and Figure 4 The monitor 100 includes a monitor body 1, a functional module 2, an air pump 3, tubing 4, a display screen 5, an operation module 6, a battery 7, and an interface.

[0038] Combination Figure 5 The monitor body 1 includes a front shell 11, a rear shell 12, a partition 13, a heat sink 14, and a cover 15. The rear shell 12 has a receiving cavity 121 for accommodating the partition 13, the heat sink 14, the functional module 2, the air pump 3, the pipeline 4, the battery 7, etc.; the front shell 11 is mounted on the rear shell 12 and covers the opening of the receiving cavity 121.

[0039] Combination Figure 6 The separator 13 is located within the receiving cavity 121 and connected to the rear shell 12. The separator 13 divides the receiving cavity 121 into an electrical cavity A and an air passage cavity B. The functional module 2, battery 7, etc., are located in the electrical cavity A, while the air pump 3, tubing 4, etc., are located in the air passage cavity B. The separator 13 effectively separates the electrical structure (including the functional module 2) and the air passage structure within the monitor body 1, thereby reducing mutual interference between the functional module 2 and the air passage structure. This ensures that the original physiological signals collected by the functional module 2 are not distorted and guarantees measurement accuracy.

[0040] Preferably, the gas passage chamber B is located below the electrical chamber A, so that even if the pipeline 4 leaks (such as gas or condensate), liquid or gas can be prevented from entering the electrical chamber A, thereby preventing short circuits and corrosion of the functional module 2, reducing equipment failures and safety hazards, and ensuring that the heat generated by the functional module 2 during operation does not directly affect the gas passage components, avoiding performance fluctuations of the gas passage due to abnormal temperature, slowing down the aging efficiency of the pipeline 4, improving safety, and reducing the risk of failure.

[0041] The separator 13 has an air pump mounting position 131 and a pipe mounting position 132 formed on the B side of the air passage cavity. The air pump 3 is installed in the air pump mounting position 131, and the pipe 4 is installed in the pipe mounting position 132. By pre-setting the air pump mounting position 131 and the pipe mounting position 132 on the separator 13, standardized positioning of the components can be achieved, eliminating the need for repeated adjustments during assembly and improving assembly efficiency. In addition, it also facilitates subsequent maintenance, eliminating the need to disassemble unrelated components, thus avoiding secondary damage and reducing maintenance difficulty.

[0042] Combination Figure 7 The heat sink 14 is mounted on the partition 13 and located on the A side of the electrical cavity. The heat sink 14 is used for assembling the functional module 2. Since the partition 13 is generally made of non-metallic materials, directly assembling the functional module 2 onto the partition 13 would weaken its heat dissipation effect. By setting up the heat sink 14, it can assist the functional module 2 in heat dissipation, improving its heat dissipation effect, ensuring the stability of the functional module 2's operation, and also helping to extend the service life of the functional module 2. Furthermore, the heat sink 14 can provide more stable support for the functional module 2 and allows the partition 13 more structural design freedom, helping to improve the functionality and practicality of the partition 13, and reducing the structural complexity of the rear shell 12 and the assembly difficulty of various components.

[0043] In this embodiment, the separator 13 has a receiving position 133 formed on the electrical cavity A side. The receiving position 133 is used to receive the battery 7. This design can simplify the structure of the back cover 12 and facilitate the manufacturing of the back cover 12 and the separator 13. On the other hand, it can make better use of the space in the receiving cavity 121, which helps to miniaturize the monitor body 1. It also facilitates the assembly of the battery 7 with the monitor body 1.

[0044] The heat sink 14 covers the receiving position 133, so that the heat sink 14 and the receiving position 133 form a battery compartment 140. Under the action of the heat sink 14, on the one hand, it can provide a certain shielding for the receiving position 133, reducing the possibility of foreign objects entering the receiving position 133, so as to ensure the smooth installation of the battery 7; on the other hand, the heat sink 14 can dissipate heat from the battery 7, which helps to extend the service life of the battery 7 and ensures the stability of the charging and discharging of the battery 7 and the safety of its use.

[0045] Preferably, in the first direction X, the hatch of the battery compartment 140 is formed at the first end of the partition 13; correspondingly, the rear shell 12 has a socket 122 at the hatch of the battery compartment 140, such that the socket 122 faces the hatch and penetrates the wall of the rear shell 12 in the first direction X. The socket 122 makes the battery 7 replaceable, so that when the monitor 100 is powered by the battery 7, the battery life of the monitor 100 can be increased by replacing the battery 7, and the maintenance and replacement of the battery 7 are also convenient.

[0046] The cover 15 is detachably connected to the rear shell 12. The cover 15 is used to cover the opening of the battery compartment 140 to prevent the battery 7 from falling out of the battery compartment 140. It can also protect the battery 7 from being damaged by collision with foreign objects and ensure the safety of the battery 7 during use.

[0047] To optimize the structural layout of the monitor body 1, the partition 13 is designed as follows: the tubing mounting position 132 and the air pump mounting position 131 are distributed along the first direction X; simultaneously, the receiving position 133 and the air pump mounting position 131 are distributed along the second direction Y. Correspondingly, the receiving position 133 and the tubing mounting position 132 are also distributed along the second direction Y (which can also be understood as distributed parallel to the second direction Y, or as the line connecting the tubing mounting position 132 and the air pump mounting position 131 being parallel to the extension direction of the receiving position 133). This design fully utilizes the space within the receiving cavity 121 and reduces the space occupied by the partition 13, air pump 3, tubing 4, and battery 7, contributing to the miniaturization of the monitor body 1.

[0048] To facilitate the assembly and disassembly of the partition 13 and the heat sink 14, simplify the assembly steps, and improve assembly efficiency, the partition 13 and the heat sink 14 are designed as follows: A stop portion 136, a pin portion 137, and a second connecting hole 138 are formed on the separator 13, and the stop portion 136, the pin portion 137, and the second connecting hole 138 are located on the A side of the electrical cavity; wherein, the stop portion 136 includes a vertical portion 1361 and a horizontal portion 1362, the vertical portion 1361 is connected between the body of the separator 13 and the horizontal portion 1362, the vertical portion 1361 extends along the normal Z of the mounting plate 141 of the heat sink 14, and the horizontal portion 1362 extends from the vertical portion 1361 along the first direction X, so that the vertical portion 1361 and the horizontal portion 1362 are arranged in an L-shape to form a locking position, the second direction Y, the first direction X and the normal Z are perpendicular to each other, and the pin portion 137 is parallel to the normal Z. Correspondingly, the mounting plate 141 of the heat sink 14 is provided with a strip groove 1412 and a first through hole 1413. The strip groove 1412 and the first through hole 1413 penetrate the mounting plate 141 in the normal direction Z. The extension direction of the strip groove 1412 is parallel to the extension direction of the horizontal part 1362 (i.e., the first direction X). When the heat sink 14 is assembled with the partition 13, the pin part 137 is located in the strip groove 1412, and then the heat sink 14 is moved towards the stop part 136 in the first direction X, so that the stop part 136 engages with the heat sink 14 to prevent the heat sink 14 from moving upward, and the first through hole 1413 is aligned with the second connecting hole 138. Then, a locking member (such as a bolt) passes through the first through hole 1413 and connects with the second connecting hole 138 to fix the heat sink 14 on the partition 13.

[0049] Combination Figure 8 To facilitate the assembly and disassembly of the partition 13 and the rear shell 12 and simplify the assembly steps, the partition 13 and the rear shell 12 are designed as follows: a tongue 139 and a connecting ear 130 are formed on the partition 13. The tongue 139 is located on the side of the partition 13, and preferably, the tongue 139 is located on both sides of the receiving position 133, along with the pipe mounting position 132 and the air pump mounting position 131. The connecting ear 130 is located at the bottom of the partition 13, and has a second through hole 1301. Correspondingly, the rear shell 12 has a plug-in portion 123 formed at the tongue 139, and a slot 124 at the connecting ear 130, with a third connecting hole 1241. When the separator 13 is assembled with the rear shell 12, the insertion part 123 is first engaged with the tongue 139, and then the connecting ear 130 is inserted into the slot 124. At this time, the tongue 139 is located below the insertion part 123, and the insertion part 123 restricts the separator 13 from moving upward through the tongue 139. Subsequently, the locking member passes through the second through hole 1301 and connects with the third connecting hole 1241 to fix the separator 13 on the rear shell 12. This design can improve assembly efficiency and facilitate maintenance.

[0050] Combination Figure 9Functional module 2 includes a main control board 21, a parameter processing board 22, and a power management board 23. The main control board 21 is electrically connected to the parameter processing board 22, the power management board 23, the air pump 3, the display screen 5, the operation module 6, and the battery 7.

[0051] The main control board 21 is mounted on the mounting plate 141 of the heat sink 14. Since the heat sink 14 is made of metal, a clearance position 1411 is provided on the mounting plate 141 to prevent interference from the electronic components on the main control board 21 and the heat sink 14 to the parameter processing board 22. The clearance position 1411 penetrates the mounting plate 141 in the Z-direction. The main control board 21 has a second clearance position at this clearance position, which also penetrates the main control board 21 in the Z-direction. The parameter processing board 22 is located at the clearance positions 1411 and 1411, maintaining a safe distance from the main control board 21 and the heat sink 14. This reduces interference to the parameter processing board 22 when acquiring various parameter signals, prevents distortion of the acquired raw physiological signals, ensures measurement accuracy, and enables medical personnel to make more accurate diagnoses and formulate more precise treatment plans.

[0052] In addition, to reliably support and fix the parameter processing plate 22, the partition 13 has a first support portion 134 and a second support portion 135 formed on the A side of the electrical cavity. The first support portion 134 has a first connecting hole 1341 at its top, and the second support portion 135 has a slot 1351, with the bottom of the slot 1351 being at the same height as the top of the first support portion 134. The first support portion 134 and the second support portion 135 are located at the clearance position 1411. When the parameter processing plate 22 is assembled with the partition 13, the plate body of the parameter processing plate 22 is inserted into the slot 1351, allowing the slot 1351 to support and position the parameter processing plate 22. Then, a locking member passes through the corresponding through hole on the plate body of the parameter processing plate 22 and connects to the first connecting hole 1341 to fix the parameter processing plate 22 onto the partition 13. Since the separator 13 is generally made of non-metallic materials, directly mounting the parameter processing board 22 onto the separator 13 will not interfere with the acquisition of various parameter signals by the parameter processing board 22. Furthermore, with the support of the first support 134 and the second support 135, the separator 13 and the parameter processing board 22 can be quickly assembled and positioned. Moreover, the design of the first connecting hole 1341 on the first support 134 and the slot 1351 on the second support 135 reduces the difficulty of disassembling and assembling the parameter processing board 22, helps improve assembly efficiency, and facilitates maintenance.

[0053] In this embodiment, the partition 13 is made of plastic material through injection molding, which can reduce the manufacturing difficulty of the partition 13 and enable the partition 13 to be molded into a complex structure and assembled with various components (such as functional module 2, air pump 3, pipeline 4, heat sink 14, etc.).

[0054] Furthermore, the rear shell 12 is also provided with a first heat dissipation hole group 125 and a second heat dissipation hole group 126. The first heat dissipation hole group 125 is located at the electrical cavity A, and the second heat dissipation hole group 126 is located at the air passage cavity B. The design of the heat dissipation hole group can assist the functional module 2, air pump 3, etc. in heat dissipation, improve the stability of the operation of the functional module 2, air pump 3, etc., and extend their service life.

[0055] Pipeline 4 is connected to the output end and interface of air pump 3, and to relevant components (such as pressure sensors and solenoid valves) on functional module 2. The interface is installed on the rear shell 12. Display screen 5 is installed on the front shell 11. Display screen 5 can be used to display various physiological parameter data collected by the assembly structure of functional module 2, so that medical staff can quickly and intuitively understand the patient's various physiological parameters. Operation module 6 is installed on the front shell 11. Operation module 6 is used in conjunction with display screen 5 so that medical staff can quickly browse and view various physiological parameters and historical parameter data collected by functional module 2 through operation module 6. At the same time, it can also control various measuring devices connected to the monitor (such as electrode pads, temperature probes, blood oxygen sensors, inflatable blood pressure cuffs, airway sensors, etc.) to re-detect the patient's various physiological parameters.

[0056] In summary, the design of the monitor 100 improves its operational stability and reliability, optimizes the layout of various components, reduces the risk of moisture-induced failure and damage to electronic components on the functional module 2, and slows down the aging rate of the pipeline 4.

[0057] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
