Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular, to a controller and massage device that combines the functions of preventing bedsores and preventing venous thrombosis. Background Technology

[0002] In the field of healthcare, the prevention of pressure ulcers and deep vein thrombosis (DVT) is a key issue in the care of long-term bedridden patients. Currently, the prevention of these two conditions mainly relies on independent devices (such as anti-pressure ulcer mattresses and anti-thrombotic massagers) for rehabilitation and care.

[0003] 1. Anti-decubitus mattresses: These typically use air or foam pads to distribute patient pressure through dynamic inflation and deflation, preventing prolonged pressure on local tissues that could lead to ischemia and necrosis. However, existing anti-decubitus mattresses inflate slowly and only address pressure distribution; they do not promote blood circulation and have no direct effect on preventing deep vein thrombosis.

[0004] 2. Anti-thrombotic massagers: These typically use intermittent pneumatic compression devices (such as airbag massagers) to periodically compress the lower limbs, promoting venous blood return and reducing the risk of deep vein thrombosis. However, these devices only address lower limb circulation issues and cannot simultaneously relieve pressure on other pressure points (such as the sacrum and shoulders). They also require additional space, increasing the complexity of nursing procedures.

[0005] Because these two types of equipment operate independently, multiple air pumps and control terminals need to be managed simultaneously during the nursing process, which not only takes up space but also increases the workload of nursing staff. In addition, the inflation efficiency of existing anti-decubitus mattresses is relatively low, affecting the user experience. Utility Model Content

[0014] Furthermore, the control components include a main control MCU, a power supply module, an AC air pump drive circuit module, a solenoid valve drive circuit module, a DC air pump drive circuit module, and an air pressure detection circuit module. The power supply module is electrically connected to the main control MCU, the AC air pump drive circuit module, the solenoid valve drive circuit module, and the DC air pump drive circuit module to provide power to each module separately. The main control MCU is electrically connected to the AC air pump drive circuit module, the solenoid valve drive circuit module, the DC air pump drive circuit module, and the air pressure detection circuit module to achieve coordinated control and coordinated control based on the air pressure detection results.

[0015] Furthermore, the control components also include: a power switch, electrically connected to the power supply module, for turning the power supply module on or off; and / or a button circuit module, electrically connected to the main control MCU, for recognizing the function selected by the user and for the main control MCU to control the AC air pump drive circuit module, the solenoid valve drive circuit module, and the DC air pump drive circuit module; and / or a display circuit module, electrically connected to the main control MCU, for human-machine interaction and to assist the user in recognizing the function in progress, the massage countdown, the massage level, and the alarm; and / or a voice circuit module, electrically connected to the main control MCU, for human-machine interaction and to implement voice broadcasting, button prompts, and alarm prompts.

[0016] According to another aspect of the present invention, a massage device combining the functions of preventing bedsores and preventing venous thrombosis is also provided, including the aforementioned controller that combines the functions of preventing bedsores and preventing venous thrombosis.

[0017] This utility model has the following beneficial effects: 1.

Detailed Implementation

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0024] like Figure 1 and Figure 2As shown, the controller integrating bedsore prevention and venous thrombosis prevention of this embodiment includes a dynamic pressure regulating device 100, an intermittent pneumatic control device 200, and a control assembly 300. A control valve group 400 is arranged between the dynamic pressure regulating device 100, the intermittent pneumatic control device 200, and between the dynamic pressure regulating device 100 and the intermittent pneumatic control device 200. The control assembly 300 is electrically connected to the dynamic pressure regulating device 100 to realize dynamic pressure regulation for bedsore prevention, and the control assembly 300 is electrically connected to the intermittent pneumatic control device 200 to realize intermittent pneumatic pressurization for thrombosis prevention, so as to realize the coordinated control of bedsore-preventing inflation and thrombosis-preventing inflation through the control assembly 300 and the control valve group 400, and increase the speed of bedsore-preventing inflation. The controller integrating bedsore prevention and venous thrombosis prevention of the present invention integrates the functions of bedsore prevention (dynamic pressure regulation) and venous thrombosis prevention (intermittent pneumatic pressurization) into a single controller, and introduces the control valve group 400 to realize coordinated control; a single control terminal manages both the bedsore prevention and thrombosis prevention functions at the same time, which reduces the space occupied by the equipment, lowers the complexity of nursing operations, improves the convenience of use, avoids the cumbersome process of separately operating the bedsore-preventing mattress and the thrombosis-preventing massager in traditional solutions, and saves nursing labor costs; the control valve group 400 is used to realize the coordinated control of bedsore-preventing inflation and thrombosis-preventing inflation, optimize air flow distribution, thereby increasing the inflation speed of the bedsore-preventing mattress, shortening the waiting time, and improving patient comfort; the dynamic pressure regulation and intermittent pneumatic pressurization can work synergistically, which can not only disperse body pressure to prevent bedsores, but also promote blood circulation in the lower limbs to prevent deep venous thrombosis, achieving a double protection effect; the control assembly 300 can adjust the operating parameters of the two modes (such as inflation frequency, pressure intensity, etc.) according to actual needs to adapt to the nursing needs of different patients; the introduction of the control valve group 400 enables the system to flexibly adjust the air flow distribution strategy according to clinical needs, with strong scalability. Through function integration, coordinated control and inflation optimization, the controller of the present invention effectively solves the problems of low efficiency and cumbersome operation caused by independent operation of equipment in the prior art, and at the same time improves the overall nursing effect of bedsore prevention and thrombosis prevention; it can be adapted to a variety of bedsore-preventing mattresses and thrombosis-preventing massage devices, improves versatility, and facilitates the upgrading and transformation of existing equipment.

[0025] as Figure 1As shown, in this embodiment, the dynamic pressure regulating device 100 includes an AC air pump 101, a first pipeline 102, and a second pipeline 103. The control valve group 400 includes a first solenoid valve 401. The AC air pump 101 is connected to the first pipeline 102 and the second pipeline 103 through the first solenoid valve 401. The AC air pump 101 is used to alternately inflate the first pipeline 102 and the second pipeline 103. Through the cooperation of the AC air pump 101 and the first solenoid valve 401, the alternating inflation of the first pipeline 102 and the second pipeline 103 is realized, allowing different areas of the anti-decubitus mattress to be periodically inflated and deflated, dynamically dispersing body pressure, avoiding long-term pressure on local tissues, and effectively reducing the risk of pressure sores. Compared with traditional single-pump or multi-pump independent control schemes, this structure simplifies the air circuit design, improves system reliability, and reduces manufacturing costs. The AC air pump 101 can quickly switch airflow direction. Combined with the precise control of the first solenoid valve 401, it reduces air pressure loss during traditional air pump switching, improves inflation response speed, shortens the time interval between mattress inflations, and enhances the anti-bedsore effect. Using a single AC air pump 101 in conjunction with the first solenoid valve 401 to switch airflow reduces energy consumption compared to multi-pump solutions, while also lowering the risk of mechanical failure and improving the long-term stability of the equipment. It reduces redundant air circuit components, making the overall air circuit system more compact and facilitating integration with the intermittent air pressure control device 200 (anti-thrombotic function), optimizing the controller layout and improving space utilization. By optimizing the air circuit control method, while ensuring the anti-bedsore function, it improves inflation efficiency, system stability, and energy saving, laying the foundation for subsequent linkage control with the anti-thrombotic function.

[0026] like Figure 1As shown, in this embodiment, the intermittent air pressure control device 200 includes a DC air pump 201 and an anti-thrombotic massage tubing 202. The control valve group 400 includes a second solenoid valve 402. The anti-thrombotic massage tubing 202 is connected to multiple airbag strips 203 (massage airbag strips). The DC air pump 201 gradually inflates the multiple airbag strips 203 sequentially through the second solenoid valve 402 and the anti-thrombotic massage tubing 202. Through the coordinated control of the DC air pump 201 and the second solenoid valve 402, the multiple airbag strips 203 are inflated sequentially according to a preset order, forming a progressive pressure mode from one end of the limb to the other, which is more in line with the physiological mechanism of venous return in the human body, effectively promoting blood circulation in the lower limbs and reducing the risk of deep vein thrombosis (DVT). Due to the gradual inflation method, the pressure change of the airbag strips 203 is more gradual, avoiding the pressure surge problem caused by the simultaneous inflation and deflation of traditional airbags, reducing patient discomfort, and reducing the risk of tissue damage caused by uneven pressure. The anti-thrombotic massage tubing 202 can... Connecting multiple independent airbag strips 203 allows for flexible adaptation to the anti-thrombotic care needs of different patients (such as postoperative patients and those on long-term bed rest) by adjusting the inflation sequence, duration, or pressure parameters, thus improving the device's versatility. The DC air pump 201 is more suitable for intermittent operation modes than the AC air pump, consuming less energy and operating with less noise, making it suitable for quiet environments such as wards. The second solenoid valve 402, as part of the control valve group 400, can work in conjunction with the anti-bedsore air circuit (such as the first solenoid valve 401) to avoid airflow conflicts and ensure efficient operation of both functions under a single controller. Through progressive inflation design and precise pressure control, the anti-thrombotic massage effect is significantly improved while simultaneously considering patient comfort and system energy efficiency, supporting the integration of anti-bedsore and anti-thrombotic functions. The sequential inflation of multiple airbag strips 203 refers to the following: instead of filling each airbag strip 203 completely at once, a predetermined amount of air is added at once, and then the next airbag strip 203 is inflated with the same predetermined amount of air, and so on, until all airbag strips 203 reach the inflation threshold. Similarly, deflation is performed in the same way, thus achieving sequential deflation. The inflation sequence of the multiple airbag strips 203 can be from left to right or right to left, from top to bottom or bottom to top; it can also be an intermittent sequential inflation; or two or three airbag strips 203 can be grouped together, and the group of airbag strips 203 can be inflated sequentially.

[0027] like Figure 1As shown, in this embodiment, a pressure detection device 500 is provided between the AC air pump 101 and the first solenoid valve 401 and / or between the DC air pump 201 and the second solenoid valve 402. The pressure detection device 500 can monitor the air circuit pressure data in real time and transmit the feedback signal to the control component 300, realizing closed-loop control of dynamic pressure regulation (preventing bedsores) and intermittent pressure boosting (preventing thrombosis), ensuring that the air pressure output accurately meets the preset parameters, avoiding nursing failure or patient discomfort caused by excessively high or low pressure; when an abnormal air pressure is detected, the control component 300 can immediately adjust the air pump power or switch the state of the control valve group 400 to prevent tissue damage or equipment damage due to pressure runaway, significantly improving system safety and fault tolerance; through air pressure feedback, the control component 300 can automatically adjust the AC air... The operating status of pump 101 and DC air pump 201 (such as start / stop frequency or speed) is monitored to prevent the air pumps from running at full load continuously, thereby reducing energy consumption and extending the service life of the air pumps. When the anti-bedsore and anti-thrombotic functions are linked, the air pressure detection device 500 can ensure the air pressure balance of the two air circuits. For example, during the inflation of the anti-thrombotic airbag strip 203, the inflation rhythm of the anti-bedsore air cushion is adjusted in real time to avoid insufficient air pressure or delay due to airflow competition, thereby improving the overall nursing efficiency. The pressure data collected by the air pressure detection device 500 can be stored or transmitted to an external terminal to provide objective evidence for nursing effect evaluation, equipment maintenance, or clinical research.

[0028] like Figure 1As shown, in this embodiment, the control valve group 400 includes a third solenoid valve 403. The AC air pump 101 and the DC air pump 201 are connected to the functional module 600 through the third solenoid valve 403. The third solenoid valve 403 serves as a gas path switching node, allowing the AC air pump 101 and the DC air pump 201 to supply air to the functional module 600 according to preset parameter values, thus achieving dynamic allocation of air pump resources. For example, when the anti-bedsore mode is primary, the AC air pump 101 and the DC air pump 201 supply air simultaneously; while when the anti-thrombosis mode is primary, to avoid affecting the anti-thrombosis experience and effect, the air supply can be switched to the AC air pump 101 to optimize airflow utilization. When a certain air pump (such as the AC air pump 101) malfunctions, the third solenoid valve 403 can quickly switch to another air pump (such as the DC air pump 201) to temporarily take over the air supply function, ensuring that the anti-bedsore or anti-thrombosis function is not interrupted, improving the fault tolerance and clinical usability of the equipment. Functional module 600 can provide air supply support for newly added pneumatic nursing devices (such as position-adjusting airbags, temperature-regulating air mattresses, etc.). By switching the third solenoid valve 403, the system can expand its functions without the need for additional air pumps, reducing modification costs. According to actual nursing needs, control component 300 can select a more energy-efficient air pump for air supply through the third solenoid valve 403; for example, in low-pressure demand scenarios, DC air pump 201 can be used first to reduce the high-energy-consumption operation time of AC air pump 101 and reduce noise. When the anti-bedsore and anti-thrombotic functions work together, the third solenoid valve 403 can coordinate the airflow distribution of the two air pumps; for example, during the inflation gap of the anti-thrombotic airbag strip 203, the remaining air volume of DC air pump 201 can be used to assist in the inflation of the anti-bedsore air mattress, shortening the overall inflation cycle and improving nursing efficiency.

[0029] like Figure 1As shown, in this embodiment, the functional module 600 includes at least one of an inflatable back-raising module 601, an inflatable leg-raising module 602, an inflatable left lateral rollover module 603, or an inflatable right lateral rollover module 604. Based on the core functions of preventing bedsores and thrombosis, the modular design integrates position adjustment functions (such as back raising, leg raising, and lateral rollover), enabling a single device to meet the complex nursing needs of patient position adjustment, pressure distribution, and blood circulation promotion, reducing the cumbersome operation of switching between multiple devices. The existing AC air pump 101 and DC air pump 201 supply air to the functional module 600 via a third solenoid valve 403, expanding the position adjustment function without the need for additional air pumps, significantly reducing hardware costs and optimizing the equipment's spatial layout. Each functional module 600 (such as back raising and leg raising) can be independently controlled, with pressure data fed back in real time by the air pressure detection device 500, ensuring uniform pressure distribution during position adjustment and avoiding safety risks caused by excessive local pressure or sudden changes in position. The body positioning function works synergistically with the anti-pressure ulcer and anti-thrombotic functions. For example, the back-raising / leg-raising module optimizes lower limb venous return when changing position, enhancing the anti-thrombotic effect; the side-turning module, through periodic turning and linkage with the anti-pressure ulcer air cushion, further reduces the risk of pressure ulcers. The control component 300 can preset body positioning programs (such as timed turning, gradual back raising, etc.), and combined with pneumatic feedback to achieve automated operation, reducing the physical burden on caregivers while ensuring standardized movements and consistent care. The modular design allows for personalized customization of body positioning programs (such as back-raising angle, side-turning range, etc.) to adapt to the rehabilitation needs of different patients, improve bed rest comfort, and is especially suitable for patients who are bedridden for a long time or have limited mobility.

[0030] like Figure 1As shown, in this embodiment, the third solenoid valve 403 adopts a multi-way directional valve, a one-way valve group, a multi-way solenoid valve group, or a composite solenoid valve. Multi-way directional valve: Enables efficient switching between multiple air paths, ensuring that the airflow from AC air pump 101 and DC air pump 201 is accurately distributed to different functional modules 600 as needed, avoiding airflow conflicts or pressure losses. One-way valve group: Prevents airflow backflow, maintains the pressure stability of the air path system, especially when multiple air pumps work together, avoiding functional failures caused by mutual airflow interference. Multi-way solenoid valve group: Achieves parallel or time-sharing control of multiple air paths by independently controlling the solenoid valves of each branch, improving system response speed and operational flexibility. Composite solenoid valve: Integrates functions such as directional switching, pressure stabilization, and backflow prevention, simplifying the air path structure and improving system integration and reliability. Different types of third solenoid valves 403 can be flexibly selected according to actual application scenarios. For example, for position adjustment functions requiring rapid switching (such as back raising and side turning), multi-way reversing valves are used to improve response speed; for functions requiring stable air pressure, such as preventing bedsores / thrombosis, one-way valve groups or composite solenoid valves are used to ensure constant pressure; through precise air circuit control, overload or dry running of the air pump is avoided, reducing energy consumption and extending the air pump's lifespan; the anti-backflow design of one-way valve groups or multi-way solenoid valve groups can prevent nursing interruptions caused by sudden drops in air pressure, improving safety. The modular valve group design facilitates fault diagnosis and component replacement, reducing maintenance costs; the integrated characteristics of composite solenoid valves reduce pipeline connection points, reducing the risk of air leakage. The diverse design of the third solenoid valve 403 significantly improves the accuracy, reliability, and adaptability of air circuit control, providing support for integrated controllers to achieve multi-functional collaboration and efficient operation.

[0031] like Figure 1 and Figure 2As shown, in this embodiment, the control component 300 includes a main control MCU 301, a power supply module 302, an AC air pump drive circuit module 303, a solenoid valve drive circuit module 304, a DC air pump drive circuit module 305, and an air pressure detection circuit module 306. The power supply module 302 is electrically connected to the main control MCU 301, the AC air pump drive circuit module 303, the solenoid valve drive circuit module 304, and the DC air pump drive circuit module 305 to provide power to each of them. The main control MCU 301 is electrically connected to the AC air pump drive circuit module 303, the solenoid valve drive circuit module 304, the DC air pump drive circuit module 305, and the air pressure detection circuit module 306 to achieve coordinated control and coordinated control based on air pressure detection results. The power supply module 302 provides power to all components of the entire controller, avoiding circuit interference and ensuring stable system operation. The main control MCU 301 centrally coordinates and manages the AC air pump 101, DC air pump 201, solenoid valve group (control valve group 400), and air pressure detection device 500. It performs precise timing control, coordinating the rhythm of dynamic inflation for pressure ulcer prevention and intermittent pressurization for thrombosis prevention, avoiding functional conflicts. It achieves adaptive adjustment, adjusting the air pump power or solenoid valve opening / closing status in real time based on feedback data from the air pressure detection circuit module 306, ensuring that the air pressure output meets preset nursing parameters. The AC air pump drive circuit module 303 and DC air pump drive circuit module 305 are adapted to the voltage and current requirements of different types of air pumps, improving drive efficiency and extending air pump life. The solenoid valve drive circuit module 304 optimizes the response speed and switching accuracy of the solenoid valves, reducing airflow delay and improving the linkage efficiency of the pressure ulcer / thrombosis prevention functions. The air pressure detection circuit module 306 converts the air pressure signal into an electrical signal and feeds it back to the main control MCU 301, forming a closed-loop control. Optionally, the main control MCU 301 also includes a drive control circuit 311, which electrically connects to the AC air pump drive circuit module 303, the solenoid valve drive circuit module 304, the DC air pump drive circuit module 305, and the air pressure detection circuit module 306 respectively.

[0032] like Figure 1 and Figure 2As shown, in this embodiment, the control component 300 further includes: a power switch 307, electrically connected to the power supply module 302, used to turn the power supply module 302 on or off; and / or a button circuit module 308, electrically connected to the main control MCU 301, used to identify the function selected by the user and for the main control MCU 301 to control the AC air pump drive circuit module 303, the solenoid valve drive circuit module 304, and the DC air pump drive circuit module 305; and / or a display circuit module 309, electrically connected to the main control MCU 301, used for human-machine interaction and to assist the user in identifying the function in progress, the massage countdown, the massage level, and the alarm; and / or a voice circuit module 310, electrically connected to the main control MCU 301, used for human-machine interaction and to implement voice broadcasting, button prompts, and alarm prompts. The power switch 307 directly controls the on / off state of the power supply module 302, providing hardware-level power management, avoiding standby power consumption, and also serving as an emergency power-off measure to enhance system safety. The button circuit module 308 allows users to select functions (such as anti-bedsore mode, anti-thrombosis mode, or body position adjustment) via physical buttons. The main control MCU 301 precisely controls each drive module based on the input signals, enabling: rapid mode switching, such as switching from dynamic inflation for anti-bedsore to intermittent pressurization for anti-thrombosis; and flexible parameter adjustment, such as adjusting massage intensity or inflation frequency to meet personalized care needs. The display circuit module 309 displays key information in real time on the screen, including: current functional status (such as mattress firmness and anti-bedsore mode); mattress inflation status (to assist caregivers in judging the equipment's operating status); massage level (to help patients or their families understand the intensity of care); and alarm prompts (such as abnormal air pressure or equipment malfunction), improving user-friendliness and controllability of the care process. The voice circuit module 310 provides the following through a broadcast function: operation guidance, prompting users that button functions or mode switching has been successful; status reminders; and alarm warnings, prioritizing fault prompts through voice, especially suitable for visually impaired or nighttime care scenarios. The collaborative design of the display circuit module 309 and the voice circuit module 310 (such as simultaneous voice broadcast when the alarm code is displayed on the screen) forms redundant prompts, ensuring that different user groups (such as nursing staff, patients, and family members) can efficiently obtain information and reduce the risk of misoperation. Alarm information is output through both display and voice channels to assist in quickly locating problems and shorten equipment downtime.

[0033] The massage device for preventing bedsores and venous thrombosis in this embodiment includes the aforementioned controller for preventing bedsores and venous thrombosis.

[0034] In practice, an integrated controller for preventing bedsores and venous thrombosis is provided, which combines dynamic pressure regulation (preventing bedsores) and intermittent air pressure inflation (preventing thrombosis) into a single control terminal. At the same time, the two inflation schemes can be linked together, which can effectively improve the inflation speed of the anti-bedsore mattress.

[0035] like Figure 2 As shown, the circuit principle is as follows: 1. The AC-DC switching power supply module converts the AC mains power input to 12V DC power to power the solenoid valve and DC air pump; 2. The 12V power supply module is then converted to 5V via DC-DC converter to power the voice module, and then the 5V is converted to 3.3V by LDO to power the display screen, air pressure detection, buttons, knobs and other circuits. 3. The AC air pump is driven by a thyristor chopper control method for inflation. The air pressure in the pipeline is monitored in real time by the air pressure detection module, and the feedback is used to adjust the air pump's power consumption. 4. The DC air pump is mainly used for intermittent air pressure pressurization (to prevent thrombosis). The pressure is controlled by air pressure monitoring during inflation. 5. The solenoid valve drive module works in conjunction with functions such as mattress undulation and intermittent lower limb pressurization to control the switching and inflation / deflation of the air circuit; 6. The button circuit module mainly identifies the function selected by the user, and the corresponding function is realized by the MCU controlling the valve and air pump; 7. The display module is a human-computer interaction module that helps users identify the ongoing function, massage countdown, massage level, and alarms, etc. 8. The voice module provides functions such as broadcasting, button prompts, and alarm alerts, enhancing the interactive experience.

[0036] like Figure 1 As shown, the present invention provides a two-in-one mattress controller for preventing bedsores and venous thrombosis, comprising a power supply, a main control unit (main control MCU 301), a display unit, a bedsore prevention module (dynamic pressure adjustment device 100), a venous thrombosis prevention module (intermittent air pressure control device 200), and a functional module 600. The bedsore prevention module includes an AC air pump 101, a first solenoid valve 401, a first pipeline 102, and a second pipeline 103. The AC air pump 101 is connected to the first pipeline 102 and the second pipeline 103 through the first solenoid valve 401, and the AC air pump 101 is used to alternately inflate the first pipeline 102 and the second pipeline 103. The anti-venous thrombosis module includes a DC air pump 201, a second solenoid valve 402, and an anti-thrombosis massage tubing 202. The anti-thrombosis massage tubing 202 is connected to multiple airbag strips 203 (massage airbag strips). The DC air pump 201 gradually inflates the multiple airbag strips 203 from bottom to top. AC air pump 101 and DC air pump 201 are connected to functional module 600 through third solenoid valve 403. Functional module 600 includes back lifting, leg lifting, left flip, and right flip. Air pressure detection devices 500 are respectively installed between AC air pump 101 and first solenoid valve 401 and between DC air pump 201 and second solenoid valve 402.

[0037] This invention provides a dual-function mattress controller that prevents bedsores and venous thrombosis, offering the following beneficial effects: 1. The AC air pump 101 is mainly used for inflating anti-bedsore mattresses and related functions; the DC air pump 201 is mainly used for preventing venous thrombosis. Through the design of solenoid valves and air circuit connections, the two functional systems are integrated into the same controller.

[0038] 2. By switching the air path through the valve, the AC air pump and the DC air pump can simultaneously inflate the airbags in the mattress, including the airbags for back lifting, leg raising, and left and right side rolling, which can greatly improve the inflation speed.

[0039] 3. Each air pump inflation circuit is equipped with an air pressure sensor to facilitate precise air pressure regulation.

[0040] 4. The LCD screen displays dynamic graphics of the anti-bedsore mattress and anti-thrombosis massage, providing a more intuitive human-computer interaction experience compared to the digital tube or key light displays on the market.

[0041] 5. Add a one-way valve assembly (third solenoid valve 403) between the AC air pump and the DC air pump. The one-way valve assembly is connected to the DC air pump, which can improve the inflation efficiency of the air mattress and meet the needs of rapid atmospheric pressure inflation in nursing mode.
