Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a multi-parameter monitoring system. Background Technology

[0002] Current portable monitoring systems generally employ a traditional approach: using a plastic back cover as the mounting base, and assembling multi-layer PCBs and functional modules one by one. The back cover serves as the load-bearing substrate, and components such as the pulse oximeter board, main control board, power supply board, sensor modules, and connectors are individually fixed to corresponding mounting posts on the back cover using screws and nuts. The front cover is then snapped on to complete the assembly. This approach is the mainstream assembly process in the portable medical device industry, suitable for small-batch, multi-model production scenarios. However, this approach has many problems, such as: low assembly efficiency, poor mass production compatibility, insufficient installation accuracy, poor assembly yield, poor maintainability, high after-sales costs, insufficient reliability, and poor user experience.

[0003] While existing technologies offer modular mounting structures for single PCBs, they only achieve pre-assembly of a single PCB and do not cover the integrated assembly of multi-layer PCBs and functional modules. They still face issues related to the assembly, positioning, and reliability of multi-layer PCB stacked structures, and cannot meet the needs of multi-parameter portable medical devices.

[0004] Meanwhile, existing monitoring systems have numerous functional accessories with many wires, which can become messy and disorderly during storage, easily causing wires to cross and tangle, damaging components. Monitors typically do not have lung function-related parameter testing capabilities, failing to meet the needs of patients requiring lung function testing. Furthermore, the monitor's test parameters can only be displayed on the screen, making it inconvenient for medical staff to view patient test records when they are not near the monitor. Summary of the Invention

[0005] This application provides a multi-parameter monitoring system to solve the problems of low assembly efficiency, poor installation accuracy, high after-sales cost, insufficient reliability, inability to achieve integrated multi-layer PCB and functional modules, difficulty in storing functional accessories, lack of lung function detection module, and inability to remotely view inspection records in existing monitoring systems.

[0006] To address the aforementioned problems, the technical solution adopted in this application is as follows: A multi-parameter monitoring system is provided, comprising a detection module, a host computer, and a storage box for housing the detection module and the host computer.

[0015] The storage box is divided into multiple storage cavities by partitions to house the detector in the detection module. Each storage cavity is equipped with a sensor, which is communicatively connected to the host.

[0021] Specifically, the multi-parameter monitoring system includes a detection module 1, a main unit 2, and a storage box 3. The storage box 3 includes a box body 31 and a cover 32. The cover 32 is movably connected to the box body 31 and covers the box body 31, used to open or close the internal space of the box body 31. In one embodiment, the box body 31 and the cover 32 can be movably connected via a hinge, a pivot, or a flexible connector. When the cover 32 is closed, the detection module 1 and the main unit 2 are stored inside the box body 31 and protected by both the box body 31 and the cover 32. By storing the detection module 1 and the main unit 2 in the same storage box 3, the overall carrying, storage, and management of the equipment are facilitated, while also protecting the internal equipment and reducing damage caused by external collisions, dust, moisture, or other environmental factors.

[0022] The detection module 1 is used to measure various physiological parameters of the subject. The detection module 1 includes a pulmonary function tester 11, which is equipped with a test mouthpiece 111. The subject exhales or blows air through the test mouthpiece 111 according to the specific instructions of the operator, which can measure the subject's pulmonary function-related parameters. In one embodiment, the pulmonary function-related parameters include, but are not limited to, forced vital capacity, forced expiratory volume in one second, peak expiratory flow rate, and other indicators, which are used to assess the respiratory system function status of the subject.

[0023] The host 2 establishes a connection with the detection module 1 via wired or wireless communication, and is used to receive physiological parameter data collected by the detection module 1, and to process, store and display the received data.

[0025] Specifically, the temperature probe 12 is used to measure the subject's body temperature parameters. The measured temperature data can be used to assess whether the subject has abnormal conditions such as fever or hypothermia. The temperature probe 12 can be a contact temperature measurement method or a non-contact temperature measurement method. The accompanying drawings of this application show a contact temperature probe, in which the temperature probe 12 obtains body temperature data by directly contacting the subject's temperature measurement site (such as the mouth, armpit, ear canal, rectum, etc.). In other embodiments, the temperature probe 12 can also be a non-contact temperature measurement method. This application does not limit the specific type of temperature probe 12.

[0026] The non-invasive blood pressure cuff 13 is used to measure the blood pressure parameters of a subject. The non-invasive blood pressure cuff 13 includes an inflatable cuff body and a connecting tubing. The cuff body contains an air bladder and is suitable for subjects with different arm circumferences. In one embodiment, see [reference needed]. Figure 3The main unit 2 includes a non-invasive blood pressure measurement button 2113, which is installed on the side of the front shell 211. When in use, the cuff body is wrapped around the test site of the subject, the operator presses the non-invasive blood pressure measurement button 2113, and the main unit 2 inflates the cuff through the trachea. By inflating and pressurizing, blood flow is blocked, and then the cuff is slowly deflated and the changes in arterial pulsation signals are detected, thereby calculating the systolic blood pressure and diastolic blood pressure.

[0027] Appendix 14 is used to measure the end-tidal carbon dioxide of the subject. The concentration of carbon dioxide is monitored to assess the subject's ventilation function, metabolic status, and airway patency. The carbon dioxide measurement accessory 14 may include either a mainstream carbon dioxide measurement accessory or a bypass carbon dioxide measurement accessory. The accompanying drawings show a mask-type bypass carbon dioxide measurement accessory. In other embodiments, other types of carbon dioxide measurement accessories may be used, and this application is not limiting.

[0028] ECG lead 15 is used to acquire the subject's electrocardiogram (ECG) signals for cardiac function assessment and cardiovascular disease diagnosis. ECG lead 15 includes multiple electrode pads and lead wires. The electrode pads are attached to specific locations on the subject's body surface, such as the chest or limbs, to pick up bioelectrical signals generated by cardiac electrical activity. In one embodiment, ECG lead 15 may include at least one configuration of three, five, or twelve leads to meet different needs ranging from baseline heart rate monitoring to comprehensive ECG analysis.

[0029] The pulse oximeter clip 16 is used to measure the blood oxygen saturation of a subject. The clip 16 has a clip-on structure and internally contains red and infrared light emitters and a photodetector. In use, the pulse oximeter clip 16 is clipped to the subject's fingertips, toes, or earlobes, and the blood oxygen saturation value is measured and calculated.

[0030] The detection module 1 can be configured according to the actual application scenario. It can be configured with only one type of detector or multiple detectors.

[0031] See Figure 3 as well as Figure 4The main unit 2 includes a housing 21, a support plate 22, a processing module 23, a display screen 2111, an alarm 2112, and a wireless communication module 231. The housing 21 includes a front shell 211 and a rear shell 212, which form a receiving cavity. The support plate 22 is located within the receiving cavity. The processing module 23 is located inside the housing 21 and is used to communicate with the detection module 1 to receive measurement data sent by the detection module 1. The processing module 23 is mounted on the support plate 22. The display screen 2111 is mounted on the housing 21 and connected to the processing module 23, used to display the measurement data sent by the detection module 1 under the control of the processing module 23. The alarm 2112 is mounted on the housing 21 and connected to the processing module 23. When the processing module 23 detects that the measurement data sent by the detection module 1 does not meet preset requirements, it controls the alarm 2112 to sound an alarm. The processing module 23 synchronizes the measurement data sent by the detection module 1 to the mobile terminal via the wireless communication module 231.

[0032] Specifically, the housing 21 includes a front housing 211 and a rear housing 212, which are connected to each other to form the internal space of the housing 21. The housing 21 is made of a material with certain strength and protective performance. In one embodiment, the material of the housing 21 includes at least one of thermoplastic resin and metal material, which is used to accommodate and protect the internal components. Preferably, the material of the housing 21 includes a polycarbonate / acrylonitrile-butadiene-styrene copolymer alloy (PC-ABS copolymer). The housing 21 made of this material can simultaneously meet the requirements of fire resistance and structural strength of medical devices.

[0033] In one embodiment, the front shell 211 and the rear shell 212 are connected by locking with a locking element. In other embodiments, the front shell 211 and the rear shell 212 are connected by an undercut connection. The front shell 211 and the rear shell 212 are formed by injection molding. Through mold design, the front shell 211 and the rear shell 212 form a mutually cooperating undercut structure. The two are locked together by the undercut structure without the need for additional locking elements. This connection method can improve installation efficiency and is suitable for high-reliability medical devices.

[0034] The support plate 22 is located in the storage cavity formed by the front shell 211 and the rear shell 212, and is used to support or fix other components in the main unit 2. In one embodiment, the material of the support plate 22 includes aerospace aluminum alloy. The support plate 22 is formed by laser cutting and bending of aerospace aluminum alloy, and the surface is anodized or sandblasted to take into account strength, appearance, and lightweight properties. In another embodiment, the material of the support plate 22 includes high-strength engineering plastics, such as polyetheretherketone (PEEK). Using this material, the support plate 22 can be injection molded in one piece after adding reinforcing ribs, which can improve production capacity and reduce material costs.

[0035] The processing module 23 is located inside the housing 21. As the core control unit of the host 2, it establishes a communication connection with the detection module 1 to receive measurement data sent by the detection module 1 and process and analyze the received data. The processing module 23 is mounted on the support plate 22. During assembly, the components of the processing module 23 are pre-installed on the support plate 22. Then, the processing module 23 and the support plate 22 are installed as a whole with the housing 21. That is, by installing the processing module 23 on the support plate 22, modular pre-assembly can be achieved. Using the support plate 22 as a unified installation standard is beneficial for overall assembly and maintenance.

[0036] In one embodiment, the processing module 23 may also be connected to an external or internal storage unit for storing historical measurement data, preset threshold parameters, or system configuration information.

[0037] The display screen 2111 is mounted on the housing 21 and electrically connected to the processing module 23. In one embodiment, the display screen 2111 is located on the front of the front housing 211 for user viewing. Under the control of the processing module 23, the display screen 2111 is used to display the measurement data sent by the detection module 1 in real time for viewing by the subject or operator. In one embodiment, the content displayed on the display screen 2111 includes one or more of the following: measurement data, waveform graph, detection time, device status, and operation prompts.

[0038] In one embodiment, the display screen 2111 may be a touch screen. When a touch screen is used, the user can select functions, set parameters, or view data through touch operations.

[0039] Alarm 2112 is mounted on housing 21 and electrically connected to processing module 23. In one embodiment, alarm 2112 is located on the upper surface of front housing 211; in other embodiments, alarm 2112 may also be located on the side of front housing 211, and this application does not impose any limitations. When processing module 23 detects that the measurement data sent by detection module 1 does not meet preset requirements, such as one or more physiological parameters exceeding the normal range, it controls alarm 2112 to issue an alarm signal to alert the subject or operator to the abnormal situation.

[0040] In one embodiment, the alarm 2112 may include at least one of a buzzer and a light strip, that is, the alarm 2112 may include only a buzzer, only a light strip, or both a buzzer and a light strip.

[0041] In one embodiment, the form of the alarm signal can be distinguished according to the level of abnormality. For example, a minor abnormality may be accompanied by an intermittent beeping sound and a flashing yellow light, while a severe abnormality may be accompanied by a continuous beeping sound and a flashing red light, so as to effectively remind the subject or operator to pay attention to the abnormal situation in a timely manner.

[0042] The wireless communication module 231 is mounted on the processing module 23. The processing module 23 establishes a wireless communication connection with an external mobile terminal through the wireless communication module 231, and synchronizes the measurement data sent by the detection module 1 to the mobile terminal in real time. The mobile terminal may include a smartphone, tablet computer, medical monitoring platform, etc., to facilitate remote viewing, storage and management of data. In one embodiment, the wireless communication module 231 may support one or more of Bluetooth, wireless local area network (WLAN), cellular mobile communication network, etc.

[0043] As can be seen from the above, this application uses a storage box 3 to store the detection module 1 and the main unit 2, which serves to fix and protect the main unit 2 and the detection module 1, and facilitates carrying. It is also equipped with a lung function testing instrument 11, which can meet the needs of lung function-related tests. At the same time, the processing module 23 is installed on the support plate 22. During the assembly process, the components of the processing module 23 can be pre-installed on the support plate 22, and then the components of the processing module 23 and the support plate 22 can be installed into the housing as a whole. This can reduce the internal assembly time of a single device from more than 30 minutes to less than 10 minutes, improve the assembly efficiency by more than 80%, reduce the assembly rework rate from 8%~12% to less than 1%, and shorten the maintenance time from more than 1 hour to less than 10 minutes, thereby improving reliability and user experience. In addition, the main unit is also equipped with a wireless communication module 231, which can synchronize data to a mobile terminal, making it convenient for the operator to view at any time.

[0044] See Figure 4 as well as Figure 5 In one embodiment of this application, the support plate 22 includes a first sub-plate 221 and a second sub-plate 222 that are connected to each other and arranged at a preset angle.

[0045] Specifically, the support plate 22 includes a first sub-plate 221 and a second sub-plate 222. The first sub-plate 221 and the second sub-plate 222 are connected to each other and are set at a preset angle, so that the support plate 22 as a whole forms a structure with a bending angle to adapt to the spatial layout inside the storage cavity and facilitate the installation of different types of components at different positions.

[0046] The processing module 23 includes a first control board 2321, a second control board 2322, and a third control board 2323. The first control board 2321 and the second control board 2322 are mounted side by side on the first sub-board 221, and the third control board 2323 is mounted across the first control board 2321 and the second control board 2322.

[0047] Specifically, the first sub-board 221 is provided with recessed holes 2213, and eight hexagonal studs (both ends have internal threads) are placed in the recessed holes 2213. The hexagonal studs are fastened to the first sub-board 221 with screws. The first control board 2321 and the second control board 2322 are placed on the upper part of the hexagonal studs in sequence, and the through holes on the first control board 2321 and the second control board 2322 are aligned with the internal threads on the hexagonal studs. The first control board 2321 and the second control board 2322 are fastened with another type of hexagonal stud (one end has an external thread and the other end has an internal thread), and the third control board 2323 is placed on the upper part of this hexagonal stud, aligned with the relevant holes. The third control board 2323 is fastened with screws to achieve the layered stacking of the circuit board (PCB). The first control board 2321, the second control board 2322, and the third control board 2323 are all located on the side of the first sub-board 221 facing the second sub-board 222, that is, in the inner space of the bending area of ​​the support plate 22, which makes full use of the internal volume of the storage cavity and facilitates the electrical connection and signal transmission between the control boards.

[0048] The first control board 2321 is equipped with a preprocessing circuit, the second control board 2322 is equipped with a data processing control circuit, and the third control board 2323 is equipped with a power supply circuit and a wireless communication module 231. The data processing control circuit is electrically connected to the preprocessing circuit, the power supply circuit, and the wireless communication module 231. The preprocessing circuit is used to preprocess the measurement data sent by the detection module 1. The data processing control circuit is used to determine whether to control the alarm 2112 to alarm based on the data sent by the preprocessing circuit. The power supply circuit is used to supply power to the host 2 (all circuits are not shown in the figure to ensure clarity of the attached diagram).

[0049] Specifically, the first control board 2321 is equipped with a preprocessing circuit, which is responsible for connecting the front-end sensors such as the detector in the detection module 1 to perform preprocessing work such as amplification, filtering, and analog-to-digital conversion on the collected raw physiological signals; the second control board 2322 is equipped with a data processing control circuit, which serves as the core computing unit of the device, runs the main control program, receives the preprocessed data and performs analysis and calculation, and finally controls the display screen 2111 to display waveforms and values, and triggers the alarm 2112 to sound an alarm when the parameters are abnormal; the third control board 2323 is equipped with a power supply circuit and a wireless communication module 231, which is mainly responsible for converting the external power supply into DC power of different voltage levels required by the internal modules of the host 2 and powering the host 2. The wireless communication module 231 is used to synchronize the monitoring data to the external mobile terminal.

[0050] In one embodiment of this application, the host 2 also includes a power adapter, which is used to connect to an external AC power source and is electrically connected to the power circuit on the third control board 2323 to convert the AC power into the working voltage required by the internal components of the host 2, thereby providing a stable power supply to the host 2.

[0051] See Figure 3 In one embodiment of this application, the host 2 further includes a battery assembly 2125, which is installed inside the rear shell 212 and electrically connected to the power circuit on the third control board 2323. The battery assembly 2125 serves as a backup power source to supply power to the host 2 when an external AC power source cannot be connected.

[0052] In one embodiment, the third control board 2323 may also integrate drive circuits for wired communication interfaces such as USB and Ethernet ports, as well as human-computer interaction interfaces such as buttons and indicator lights.

[0053] By arranging circuits with different functions on three control boards and using a bridging installation method, the processing module 23 achieves a layout with clear functional partitioning and compact space utilization, which is conducive to improving the reliability and maintainability of the system.

[0054] See Figure 5 In one embodiment of this application, at least one weight-reducing groove 2211 is provided on the first sub-plate 221. Specifically, the weight-reducing groove 2211 is formed by removing material from non-stressed or non-installation areas of the first sub-plate 221, and is used to reduce the weight of the support plate 22 while ensuring the structural strength of the support plate 22, thereby reducing the overall weight of the multi-parameter monitoring system and adapting to the needs of portable medical devices. The number of weight-reducing grooves 2211 can be selected and set according to different situations, and this application does not impose a specific limitation on the number of weight-reducing grooves 2211.

[0055] In one embodiment, two weight-reduction grooves 2211 are provided on the first sub-board 221, which can reduce the overall weight of the multi-parameter monitoring system by 5%.

[0057] Specifically, at least one side of the first sub-plate 221 is provided with a positioning groove 2212, and the interior of the rear shell 212 is provided with a boss 2121. The processing module 23 is installed on the support plate 22, and the positioning groove 2212 on the support plate 22 is aligned with the boss 2121 inside the rear shell 212. Finally, screws and other locking parts are used to fix the support plate 22 and the rear shell 212, realizing one-click pre-positioning of the modular structure without the need for individual component alignment.

[0058] In another embodiment, the support plate 22 and the rear shell 212 are connected by a snap-lock structure. A hook is provided on the rear shell 212, and a corresponding slot is provided on the support plate 22. When the support plate 22 is installed in place, the hook and slot engage, achieving quick locking. This snap-lock structure facilitates the installation and removal of the support plate 22, eliminating the need for screws or other locking components, thus improving assembly and disassembly efficiency and making it suitable for scenarios requiring frequent maintenance.

[0059] See Figure 4 as well as Figure 5 In one embodiment of this application, the processing module 23 further includes a pulse oximeter plate 2331, which is mounted on the second sub-plate 222 and located on the side of the second sub-plate 222 facing the first sub-plate 221.

[0060] Specifically, the second sub-plate 222 is provided with a protrusion 2222, and the pulse oximetry plate 2331 is connected to the second sub-plate 222 through the protrusion 2222 and fixed with a locking member. The pulse oximetry plate 2331 is located on the side of the second sub-plate 222 facing the first sub-plate 221, that is, in the space inside the bending area of ​​the support plate 22. It is arranged opposite to the first control plate 2321, the second control plate 2322, the third control plate 2323 and other components, which facilitates connection with other circuits of the host 2, and makes full use of the internal space of the storage cavity.

[0061] The processing module 23 also includes a fixing plate 234, which is mounted side-by-side with the pulse oximeter plate 2331 on the second sub-plate 222. Specifically, the second sub-plate 222 is provided with threaded holes 2223, and the fixing plate 234 is connected to the second sub-plate 222 through the threaded holes 2223 and fixed with locking components. The fixing plate 234 and the pulse oximeter plate 2331 are mounted side-by-side on the second sub-plate 222, both located on the side of the second sub-plate 222 facing the first sub-plate 221.

[0062] The processing module 23 also includes a pulse oximetry module 2332, which is connected to both the pulse oximetry plate 2331 and the mounting plate 234. Specifically, the pulse oximetry module 2332 is mounted on the pulse oximetry plate 2331, which acts as a circuit board providing electrical connections and mechanical support for the module. The pulse oximetry module 2332 processes data sent by pulse oximetry measuring instruments such as the pulse oximetry finger clip 16. The processed data can be transmitted to other circuits in the host 2 for further analysis or display. Simultaneously, the pulse oximetry module 2332 is also connected to the mounting plate 234 via screws and hexagonal nuts, providing additional mechanical support and ensuring the stability and reliability of the module during operation.

[0063] See Figure 5 as well as Figure 6In one embodiment of this application, the second sub-plate 222 is provided with at least one through hole 2224 and at least one waist-shaped hole 2225, and multiple locking members pass through the through hole 2224 and the waist-shaped hole 2225 respectively to lock the support plate 22 and the rear shell 212.

[0064] Specifically, the through hole 2224 is used to insert screws to lock the support plate 22 to the rear shell 212. The waist-shaped hole 2225 is used to compensate for assembly tolerances and adapt to the size fluctuations of mass production. It is also used to lock the support plate 22 and the processing module 23 to the rear shell 212 as a whole, complete the internal component assembly, and connect the internal cables.

[0065] In one embodiment of this application, the locking component used to fix the support plate 22, the rear shell 212 and other components is made of at least one of stainless steel, carbon steel, copper and PEEK. Depending on the actual application requirements, a single material or a combination of multiple materials can be selected. In addition, the locking component can be equipped with a spring washer or a flat washer during assembly to prevent loosening caused by long-term vibration.

[0066] In one embodiment, the maintenance steps for the host 2 include: S100: Remove the locking mechanism of the front cover 211 and remove the front cover 211; S200: Remove the locking mechanism between the support plate 22 and the rear shell 212, and remove the support plate 22 and the processing module 23 as a whole; S300: For faulty modules, repair and replacement can be completed on the processing module 23 without disassembling unrelated components; S400: After passing the test, reinstall the support plate 22 and processing module 23 back into the rear shell 212, and fasten the front shell 211 to complete the repair.

[0067] See Figure 5 In one embodiment of this application, at least one side of the second sub-board 222 is provided with a clearance groove 2221. Specifically, the clearance groove 2221 is used to provide clearance space for other structures on the rear shell 212 or cables passing through this side, so as to avoid interference between the second sub-board 222 and surrounding components, and at the same time facilitate assembly and wiring.

[0068] See Figure 3 In one embodiment of this application, the host 2 includes an interface 2122 mounted on the housing 21, and the detector in the detection module 1 is connected to the host 2 through the interface 2122.

[0069] Specifically, interface 2122 is installed on the side of the rear housing 212 for easy plugging and unplugging and management of the wiring. In other embodiments, interface 2122 can also be installed on the back of the rear housing 212. Interface 2122 can be a single-interface layout, or a multi-interface layout when the detection module 1 is configured with multiple detectors. The detectors in the detection module 1 establish a wired connection with the host 2 through interface 2122, transmitting the data collected by the detection module 1 to the host 2 in real time for subsequent processing and analysis.

[0070] See Figure 4 as well as Figure 7 In one embodiment, the detector in the detection module 1 is connected to the host 2 wirelessly. Specifically, the processing module 23 in the host 2 is equipped with a wireless communication module 231, and the detector in the detection module 1 also has wireless communication capabilities. The detector and the host 2 establish a wireless connection, enabling the data collected by the detection module 1 to be transmitted to the host 2 in real time for subsequent processing and analysis. In one embodiment, the wireless communication module 231 may support one or more of Bluetooth, wireless local area network (WLAN), and cellular mobile communication network.

[0071] Wireless communication avoids the constraints of wires, allowing the detection module 1 and the host 2 to be placed separately, improving the flexibility and portability of the device. When subjects measure physiological parameters, they are no longer limited by the length of the connecting wire, making the operation more free and convenient.

[0072] See Figure 3 In one embodiment of this application, the host 2 further includes a storage bracket 2123, which is located outside the housing 21 and connected to the housing 21, for placing the lung function tester 11.

[0073] Specifically, the storage bracket 2123 is located on the side of the rear shell 212 for easy access. The internal contour of the storage bracket 2123 matches the external contour of the pulmonary function testing device 11. When the pulmonary function testing device 11 is not in use, it can be placed in the storage bracket 2123 to avoid loss or damage due to careless placement. When the pulmonary function testing device 11 needs to be used, the operator can easily remove it from the storage bracket 2123.

[0074] In one embodiment, the connection method between the storage bracket 2123 and the back shell 212 may include one of the following: snap-fit ​​connection, adhesive attachment, or integral molding.

[0075] In one embodiment of this application, the main unit 2 further includes a handle 2124, which is located outside the housing 21 and connected to the housing 21. Specifically, the handle 2124 is located at the upper position on the back of the rear housing 212.

[0076] In one embodiment, the handle 2124 is rotatably connected to the housing 21, for example, by a pivot or hinge structure. When the handle 2124 is needed, the user can flip it upward to a position that is easy to grip; when it is not needed, the handle 2124 can be folded downward to fit against the surface of the housing 21, reducing space occupation and making it easy to store and store.

[0077] See Figure 8 In one embodiment of this application, the host 2 further includes a support component 24, which is installed on the side of the housing 21 away from the display screen 2111 and is used to support the host 2 and adjust the support angle of the host 2.

[0078] Specifically, the support component 24 is located at the lower part of the back of the housing 21. When the user needs to place the main unit 2 on a desktop or other horizontal platform for use, the support component 24 can make the main unit 2 stand on the platform at a certain tilt angle, so that the operator can view the measurement data on the display screen 2111 and perform operations.

[0079] In one embodiment, the angle between the host 2 and the horizontal plane can be adjusted to 45°~90°. Preferably, the angle between the host 2 and the horizontal plane is 70°, which makes it more convenient for the operator to observe the display screen 2111.

[0080] In one embodiment of this application, the support assembly 24 includes a connecting shaft 241, a support base 242, and a damper 243. Specifically, one end of the connecting shaft 241 is rotatably connected to the housing 21, and the other end is connected to the support base 242, allowing the housing 21 to rotate freely relative to the support base 242 within a certain angle range. The support base 242 is used to place on a table or other horizontal surface, serving to support the host 2. The damper 243 is connected to the connecting shaft 241 and the host 2, and is used to provide appropriate damping force during the relative rotation between the connecting shaft 241 and the housing 21. The damper 243 can be a rotational viscous damper from the prior art, which will not be described in detail here.

[0081] By setting up the damper 243, when the operator adjusts the support angle of the main unit 2, the rotation of the connecting shaft 241 will be subject to uniform resistance, allowing the main unit 2 to remain at any rotational position without sliding due to gravity. For example, if the operator tilts the main unit 2 backward to a certain angle and then releases it, the resistance generated by the damper 243 is sufficient to balance the component of gravity of the main unit 2, thereby keeping the main unit 2 stably at that tilt angle. When the operator needs to change the angle, only a certain external force needs to be applied to overcome the resistance of the damper 243, and the main unit 2 can be smoothly adjusted to the new position.

[0082] In one embodiment, the side of the support base 242 that contacts the placement plane may be provided with an anti-slip material, such as a rubber pad or a silicone pad, to increase friction and prevent the host 2 from sliding during use.

[0083] In one embodiment of this application, the multi-parameter monitoring system further includes a disinfection component (not shown) for disinfecting the detectors in the detection module 1. Specifically, when not in use, the disinfection component is stored in a storage box 3, along with the detectors in the detection module 1, in a designated location within the box 31. When a detector needs to be disinfected, the operator removes the disinfection component from the storage box 3 and disinfects the detector.

[0084] In one embodiment, the disinfection component may include at least one of ultraviolet disinfection, ozone disinfection, alcohol spray disinfection, and disinfectant wipes. For example, when the disinfection component is ultraviolet disinfection, it may be a portable ultraviolet disinfection lamp. The disinfection component can perform real-time disinfection of the detector in the detection module 1 to prevent cross-infection and ensure the safety of the subject.

[0085] See Figure 1 In one embodiment of this application, the interior of the storage box 3 is divided into multiple storage cavities 33 by partitions for storing the detectors in the detection module 1. Specifically, the interior of the storage box 3 is divided by partitions to form multiple independent storage cavities 33, each of which is used to store different detectors or other accessories in the detection module 1.

[0086] In one embodiment, the partition can be a fixed structure, for example, the partition is integrally formed with the housing 31 or fixedly installed by a slot, forming storage cavities 33 of different sizes and shapes to adapt to the external dimensions of different detectors. In other embodiments, the partition can also be a detachable or adjustable structure, allowing the user to flexibly adjust the layout and size of the storage cavities 33 according to actual needs.

[0087] Each storage cavity 33 is equipped with a sensor (not shown in the figure). The sensor is connected to the host 2 for communication. When the host 2 detects that the time the detector has been out of the storage cavity 33 has reached the time threshold based on the data collected by the sensor, the host 2 controls the alarm 2112 to sound an alarm.

[0088] Specifically, the sensor can be set on the surface inside each storage cavity 33 or integrated inside the housing 31, and set for each storage cavity 33. When the operator takes the detector out of the storage cavity 33 for use, the sensor immediately detects the change in status and sends the signal to the host 2 in real time. The host 2 continuously monitors the duration of the detector being detached from the storage cavity 33. When the host 2 detects that the duration of a detector being detached from the storage cavity 33 reaches the preset duration threshold based on the data collected by the sensor, the host 2 controls the alarm 2112 to issue an alarm signal.

[0089] In one embodiment, the sensor may include one of a photoelectric sensor, a pressure sensor, or a Hall sensor. For example, a photoelectric sensor determines whether the detector is in place by emitting and receiving infrared light; a pressure sensor determines the presence of the detector based on the pressure value applied by the detector; and a Hall sensor achieves non-contact detection by cooperating with a magnet on the detector.

[0090] In one embodiment of this application, the storage box 3 also includes a storage box handle 34, which is installed on the outer surface of the box body 31. In other embodiments, it can also be installed on the outer surface of the cover 32, making it convenient for users to carry the entire storage box 3 and improving the overall portability of the multi-parameter monitoring system.

[0091] Figure 9 This is a structural diagram of the multi-parameter monitoring system in use according to one embodiment of this application. The pulmonary function tester 11 transmits pulmonary function data to the host 2 via wireless communication. Other testers in the test module 1 are connected to the host 2 via physical lines. The host 2 synchronizes the measurement data of the testers, including the pulmonary function tester 11, to the mobile terminal device via wireless communication. Users can view and retrieve the subject's measurement data on the mobile terminal anytime and anywhere, which greatly improves the user's work efficiency.

[0092] Figure 10 This is a schematic diagram of the structure of the multi-parameter monitoring system in the storage state according to one embodiment of this application. The detection module 1, the host 2 and other functional accessories are stored in the storage box 3. The components do not interfere with each other and will not collide, which greatly reduces the possibility of component damage and facilitates transportation and carrying.

[0093] See Figure 3 In one embodiment of this application, the host 2 further includes a switch button 2114, which is mounted on the outer surface of the housing 21, preferably on the side of the front housing 211. The switch button 2114 is electrically connected to the processing module 23 and is used to control the start and stop of the host 2. When the user presses the switch button 2114, the host 2 performs a power-on or power-off operation.

[0094] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
