Intelligent pneumatic positioning nursing system

Abstract

This application relates to the field of medical care and discloses an intelligent pneumatic positioning care system. This system enables elderly individuals to safely transition from a lying to a sitting position without changing their existing bed, providing ample lateral support throughout the process to prevent rollover or falls. The system includes: a wedge-shaped main air cushion, used to elevate the upper body from a lying to a sitting position after inflation; two side air cushions, respectively located on both sides of the main air cushion's upper surface, used to provide lateral support after inflation; and a one-way valve with an opening pressure, located between the side air cushions and the main air cushion. When the pressure difference between the side air cushions and the main air cushion is greater than the opening pressure, the one-way valve opens, allowing gas from the side air cushions to enter the main air cushion; when the pressure difference is less than the opening pressure, the one-way valve closes, cutting off the gas connection between the side air cushions and the main air cushion.

Description

Technical Field

[0001] This application relates to the field of medical care, and in particular to bed care assistive devices. Background Technology

[0002] This section is intended to provide background or context for understanding the implementation of this application and is for reference only. It should not be construed as an admission by the applicant that this section pertains to prior art that was disclosed before the filing date of this application.

[0003] With the accelerating aging of the population, the demand for bed care for disabled or semi-disabled elderly people is increasing. During daily care, the elderly often need to change from a lying position to a sitting or semi-sitting position when eating, drinking, taking medication, or performing other care activities. This posture change is quite difficult for elderly people with limited mobility, and improper handling may lead to safety risks such as choking, aspiration, or falls due to postural instability.

[0004] Currently, the main types of devices used to assist the elderly in transitioning from a lying to a sitting position are as follows:

[0005] Multifunctional nursing beds: These beds allow the headboard to be raised by hand or electric mechanical means, enabling the elderly person to sit up. These devices are complex, expensive, and bulky, requiring a complete replacement of the existing bed. This places significant financial and space constraints on small households or nursing homes with short equipment replacement cycles.

[0006] Simple backrests or cushions: These devices involve placing multiple layers of cushions or specially designed pillows behind the elderly person's back and manually adjusting their posture. While inexpensive, these methods require caregivers with a certain level of physical strength and skill, and lack lateral support. The elderly person is prone to tilting or slipping due to instability, posing a safety hazard.

[0007] External lifting devices: These assist elderly people in sitting up or getting up by using a robotic arm or rope system installed beside the bed. These devices are complex in structure, cumbersome to install, require additional space for the support system, and are inconvenient to operate, making them unsuitable for daily home use.

[0008] Simple air cushion device: It raises the upper body of the elderly by inflating. Most existing simple air cushions are single wedge-shaped structures. Although they can help the elderly sit up to a certain extent, they lack lateral support, and the elderly are prone to tipping over during the sitting-up process. In addition, the inflation and deflation process lacks a coordination mechanism, making the operation complicated. Caregivers need to manually control the inflation and deflation sequence and timing, which increases the difficulty of use.

[0009] The aforementioned existing technologies have the following problems that urgently need to be addressed:

[0010] Economic and space constraints: Existing professional nursing beds are expensive and bulky, making them unsuitable for most families and small nursing facilities; while simple cushions lack the necessary safety features.

[0011] Safety hazard: Without effective lateral support, the elderly are prone to tipping over or falling when changing positions.

[0012] The procedure is complex: it requires nursing staff to have professional knowledge or strong physical strength, which increases the difficulty and burden of nursing care.

[0013] Insufficient comfort: The posture change process is not smooth and natural enough, which may cause discomfort or resistance in the elderly.

[0014] Therefore, there is an urgent need for a bed care assistive device that is both economical and practical, as well as safe and reliable. Summary of the Invention

[0015] The purpose of this application is to provide an intelligent pneumatically controlled positioning care system that enables elderly people to safely transition from a lying to a sitting position without changing their existing bed, and provides sufficient lateral support throughout the process to prevent them from rolling over or falling.

[0016] This application discloses an intelligent pneumatically controlled positioning care system, comprising:

[0017] The wedge-shaped main air cushion is set in the upper part of the bed. Before inflation, the upper surface of the main air cushion is horizontal. After full inflation, the upper surface of the main air cushion is roughly inclined. It is used to raise the upper body of the human body from a lying position to a sitting position after inflation.

[0018] Two side air cushions are respectively set on both sides of the upper surface of the main air cushion, and are used to provide wrapping support for both sides of the human body after inflation;

[0019] A one-way valve with an opening pressure is disposed between the side air cushion and the main air cushion; when the pressure difference between the side air cushion and the main air cushion is greater than or equal to the opening pressure, the one-way valve opens, allowing gas in the side air cushion to enter the main air cushion; when the pressure difference between the side air cushion and the main air cushion is less than the opening pressure, the one-way valve closes, cutting off the gas connection between the side air cushion and the main air cushion.

[0020] The air intake interface is connected to the gas of the two side air cushions respectively, and is used to connect to an external air source;

[0021] The exhaust port is connected to the main air cushion gas. When the exhaust port is in the open state, the gas in the main air cushion is discharged through the exhaust port.

[0022] In a preferred embodiment, when the external air source inflates the main air cushion through the air inlet, the one-way valve is initially closed, and the two side air cushions inflate before the main air cushion. As the air pressure in the two side air cushions gradually increases, when the pressure difference between the two side air cushions and the main air cushion reaches the opening pressure, the one-way valve opens, and gas enters the main air cushion from the two side air cushions through the one-way valve, thereby inflating the main air cushion.

[0023] When the exhaust port is opened, the one-way valve is initially closed, and the gas in the main air cushion is released through the exhaust port before the two side air cushions. As the air pressure of the main air cushion decreases, when the difference between the air pressure of the two side air cushions and the air pressure of the main air cushion is greater than the opening pressure, the one-way valve opens, and the gas from the two side air cushions enters the main air cushion through the one-way valve and is finally discharged to the outside through the exhaust port.

[0024] In a preferred embodiment, the exhaust port is connected to a vacuum pump. During the exhaust phase, the vacuum pump is used to extract air, creating a negative pressure within the main air cushion. This causes the pressure difference between the two side air cushions and the main air cushion to exceed the opening pressure, thereby opening the one-way valve to exhaust the gas from the two side air cushions.

[0025] In a preferred embodiment, a support channel is provided between the exhaust port and the one-way valve to maintain gas communication between the main air cushion and the one-way valve even when the gas in the main air cushion is evacuated. This allows the external negative pressure generated by the vacuum pump to be transmitted to the main air cushion side of the one-way valve through the exhaust port, so that the gas in the two side air cushions can enter the main air cushion through the one-way valve and eventually be discharged.

[0026] In a preferred embodiment, the two side air cushions are connected by a gas pipe so that the air pressure in the two side air cushions is approximately the same.

[0027] In a preferred embodiment, the external air source is an electric air pump used for inflation through the air inlet.

[0028] In a preferred embodiment, the surfaces of the main air cushion and the two side air cushions that come into contact with the human body are all made of a flexible, non-slip material.

[0029] In a preferred embodiment, an overpressure protection valve is also included, which is disposed on the main air cushion and the two side air cushions, and automatically opens to release air when the pressure inside the air cushion exceeds a preset safety value.

[0030] In a preferred embodiment, the system further includes a charge / pump electric air pump, the charge port of which is connected to the air inlet and the pump port of which is connected to the exhaust port.

[0031] In a preferred embodiment, a control device is also included for controlling the electric air pump to perform inflation and deflation operations at a preset time.

[0032] This embodiment of the application, through the design of combining a wedge-shaped main air cushion, two side air cushions, a one-way valve with opening pressure, and independent air inlet and outlet ports, can automatically complete the staged inflation and deflation process: first inflating the side air cushions to form lateral support, then inflating the main air cushion to gradually allow the elderly to sit up; and a safe deflation process of first deflating the main air cushion and then deflating the side air cushions. This structure and working method solve the problems of high cost, large space occupation, complex operation, and insufficient safety of existing nursing beds, greatly reducing the nursing threshold, improving the safety and comfort of the elderly during the sitting and standing process, and the device can be folded and stored after deflation, saving space.

[0033] Furthermore, by connecting a vacuum pump through the exhaust port to create negative pressure, the problem that relying solely on pressure difference may not be able to completely vent the side air cushion can be solved, ensuring that the device can be completely vented after use, making it easy to store and assemble.

[0034] Furthermore, by setting a support channel between the exhaust port and the one-way valve, it can be ensured that the main air cushion gas remains connected to the one-way valve after it is evacuated, so that the negative pressure generated by the vacuum pump can be smoothly transmitted to the one-way valve, thereby ensuring that the gas in the side air cushion can be completely discharged, improving the reliability and efficiency of the exhaust system.

[0035] Furthermore, by connecting the two side air cushions through pipes, it can be ensured that the air pressure inside the air cushions on both sides remains balanced, providing uniform lateral support and preventing the elderly from tilting due to uneven force on both sides, thus enhancing the stability and safety during the care process.

[0036] Furthermore, by using an electric air pump as an external air source, a stable and reliable air supply can be provided, reducing the physical burden on caregivers and improving inflation efficiency and ease of use.

[0037] Furthermore, by using flexible, non-slip materials on the surfaces of the main and side air cushions that come into contact with the human body, the comfort of elderly users can be increased, slippage can be prevented during posture changes, and overall safety and user experience can be improved.

[0038] Furthermore, by setting an overpressure protection valve, the air cushion can be automatically vented when the pressure inside exceeds a preset safety value, preventing equipment damage or safety hazards caused by over-inflation, thus increasing the safety and service life of the device.

[0039] Furthermore, by adopting a dual-purpose electric air pump for both inflation and deflation, the inflation and deflation functions can be integrated into one unit, reducing the number of devices and the space occupied, simplifying the operation steps, and improving the overall ease of use.

[0040] Furthermore, by adding a control device to control the air pump to perform inflation and deflation operations at preset times, an automatic timed control function can be realized, reducing the workload of caregivers, improving care efficiency and accuracy, and also allowing for preset usage times according to the specific needs of the elderly, thus achieving a more intelligent and humanized care method.

[0041] The various technical features disclosed in the above-described invention, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which should be considered as having been recorded in this specification), unless such a combination of technical features is technically infeasible. For example, in one example, feature A+B+C is disclosed, and in another example, feature A+B+D+E is disclosed. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; it is impossible to use both simultaneously. Feature E can be technically combined with feature C. Therefore, the solution A+B+C+D should not be considered as having been recorded because it is technically infeasible, while the solution A+B+C+E should be considered as having been recorded.

[0050] In the following description, many technical details are presented to help the reader better understand this application. However, those skilled in the art will understand that the technical solutions claimed in this application can be implemented even without these technical details and various variations and modifications based on the following embodiments.

[0051] Explanation of some concepts:

[0052] One-way valves with opening pressure: These valves have a preset opening pressure on the valve core. Their main characteristic is that they only open when the inlet pressure exceeds the outlet pressure by a certain value (opening pressure / rupture pressure). Gas can only flow from the high-pressure side to the low-pressure side, and the valve automatically closes when the pressure difference is below a threshold. Common implementation methods include: Spring-loaded type: This is the most common design, using a spring to apply a preset force to the valve core. The valve only opens when the gas pressure is greater than the spring force; the spring pressure can be adjusted to change the opening threshold. Gravity-loaded type: Using a weight to apply a downward force to the valve core, suitable for vertical installations; the opening pressure depends on the mass of the weight. Magnetic type: Using a magnet to provide the closing force; the valve opens when the gas pressure exceeds the magnetic force. Lever type: Utilizing the lever principle to increase the closing force.

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0054] The embodiments of this application relate to an intelligent pneumatically controlled positioning care system, one embodiment of which is, for example... Figure 1 As shown, the intelligent pneumatic positioning care system includes:

[0055] The wedge-shaped main air cushion 1 is located in the upper part of the bed. Before inflation, the upper surface of the main air cushion 1 is horizontal, and after full inflation, the upper surface of the main air cushion 1 is roughly inclined. It is used to raise the upper body from a lying position to a sitting position after inflation. The upper part of the bed refers to the part roughly half on the side of the head, which roughly corresponds to the part above the buttocks when the human body is lying on the bed.

[0056] Two side air cushions 2 are respectively set on both sides of the upper surface of the main air cushion 1, and are used to provide wrapping support for the sides of the human body after inflation.

[0057] A one-way valve 4 with opening pressure is installed between the two side air cushions 2 and the main air cushion 1. It opens when the difference between the air pressure of the two side air cushions 2 and the air pressure of the main air cushion 1 is greater than or equal to the opening pressure, allowing gas from the two side air cushions 2 to enter the main air cushion 1. It closes when the difference between the air pressure of the two side air cushions 2 and the air pressure of the main air cushion 1 is less than the opening pressure, cutting off the gas connection between the two side air cushions 2 and the main air cushion 1.

[0058] The air intake port 6 is connected to the gas of the two side air cushions 2 respectively, and is used to connect to an external air source. Figure 1(Not shown in the image). External air supply can be achieved in various ways. The most common and convenient method is an electric air pump. For example, a dedicated medical-grade electric air pump with pressure control can be used. Portable electric air pumps, which can be plugged in or battery-powered, can also be used. Intelligent air pumps with built-in micro-control systems can also be used, allowing for preset inflation programs and pressure control. Manual air pumps, such as foot-operated pumps or manual air pumps, can also be used as a backup option. Additionally, centralized medical air supply systems can be used, suitable for hospitals or specialized nursing facilities. Air inlet 6 can be one or more. Figure 1 There are two air inlets 6 in the middle, and the two air inlets 6 can be connected to the air outlet of the electric air pump through a three-way pipe.

[0059] Exhaust port 3 is connected to the main air cushion 1. When exhaust port 3 is open, the gas inside the main air cushion 1 is discharged through exhaust port 3. There can be one or more exhaust ports 3. For example... Figure 1 There are two exhaust ports 3 in the middle, which can be connected to the suction port of the air pump and the two exhaust ports 3 through a three-way pipe.

[0060] When an external air source inflates the main air cushion 1 through the air inlet 6, the one-way valve 4 is initially closed, and the two side air cushions 2 inflate before the main air cushion 1. As the air pressure in the two side air cushions 2 gradually increases, when the pressure difference between the two side air cushions 2 and the main air cushion 1 reaches the opening pressure, the one-way valve 4 opens, and gas enters the main air cushion 1 from the two side air cushions 2 through the one-way valve 4, thereby inflating the main air cushion 1.

[0061] When the exhaust port 3 is opened, the one-way valve 4 is initially closed, and the gas in the main air cushion 1 is released through the exhaust port 3 before the two side air cushions 2. As the air pressure in the main air cushion 1 continues to decrease, when the pressure difference between the two side air cushions 2 and the main air cushion 1 exceeds the opening pressure, the one-way valve 4 opens, and the gas in the two side air cushions 2 enters the main air cushion 1 through the one-way valve 4 and is finally discharged to the outside through the exhaust port 3.

[0062] The technical solution of this application does not require replacing the existing bed frame. The intelligent air-controlled positioning care system can be placed on the upper part of the existing bed frame, making it applicable to various bed frames and highly compatible.

[0063] Optionally, in one embodiment, the exhaust port 3 is connected to a vacuum pump. During the exhaust phase, the vacuum pump is used to extract air, creating a negative pressure in the main air cushion 1. This causes the pressure difference between the two side air cushions 2 and the main air cushion 1 to be greater than the opening pressure, thereby opening the one-way valve 4 to exhaust the gas in the two side air cushions 2.

[0064] Optionally, in one embodiment, a support channel 5 is provided between the exhaust port 3 and the one-way valve 4 to maintain gas communication between the main air cushion 1 and the one-way valve 4 even when the gas in the main air cushion 1 is evacuated. This allows the external negative pressure generated by the vacuum pump to be transmitted to one side of the main air cushion 1 through the exhaust port 3, so that the gas in the two side air cushions 2 can enter the main air cushion 1 through the one-way valve 4 and eventually be discharged. Figure 1 In the middle, the two side air cushions 2 are connected to the main air cushion 1 through a one-way valve 4. The main air cushion 1 is provided with two exhaust ports 3 (each corresponding to a one-way valve 4 in position). A support channel 5 is provided between each exhaust port 3 and the corresponding one-way valve 4.

[0065] The supporting channel 5 can be implemented in several ways. For example, it can be a hollow pipe structure made of rigid material, connecting the exhaust port 3 and the one-way valve 4. The pipe wall has numerous small through-holes to connect to the internal space of the main airbag, allowing gas from inside the main airbag to enter the hollow pipe and ultimately exit from the exhaust port 3. Alternatively, the supporting channel 5 can be an anti-collapse pipe with a corrugated or pleated design. Yet another example is a breathable pipe with a mesh support structure.

[0066] Optionally, in one embodiment, the two side air cushions 2 are connected by a gas pipe so that the gas pressure in the two side air cushions 2 is approximately the same. In this case, only one air inlet 6 and one air outlet 3 are needed; alternatively, only one side air cushion 2 can be connected to the main air cushion 1 through a one-way valve 4.

[0067] Optionally, in one embodiment, the surfaces of the main air cushion 1 and the two side air cushions 2 that come into contact with the human body are made of a flexible, non-slip material.

[0068] Optionally, in one embodiment, the intelligent pneumatic positioning care system further includes one or more overpressure protection valves, which are disposed on the main air cushion 1 and the two side air cushions 2, and automatically open to release air when the pressure inside the air cushion exceeds a preset safety value.

[0069] Optionally, in one embodiment, the intelligent pneumatic positioning care system further includes a dual-purpose electric air pump for both inflation and deflation. The inflation port of the dual-purpose electric air pump is connected to the air inlet 6, and the deflation port is connected to the exhaust port 3. The dual-purpose electric air pump may have an adjustable pressure control function, automatically stopping operation when inflation or deflation reaches a preset pressure.

[0070] Optionally, in one embodiment, the air intake port 6 includes a quick-connect device for quickly connecting to or disconnecting from an external air source. The main air cushion 1 and the two side air cushions 2 can be folded and stored in the deflated state.

[0071] Optionally, in one embodiment, the intelligent air-controlled positioning care system further includes a fixing strap, which is disposed around the bottom periphery of the main air cushion 1 for fixing the intelligent air-controlled positioning care system to the mattress.

[0072] Optionally, in one embodiment, the inner surfaces of the two side air cushions 2 may be designed in an arc shape to conform to the curve of the human body's side profile.

[0073] Optionally, in one embodiment, the main air cushion 1 and the two side air cushions 2 of the intelligent pneumatic positioning care system are provided with a micro-arched anti-shear surface structure to reduce the shear force between the patient and the air cushion surface and prevent skin damage caused by prolonged bed rest.

[0074] The micro-arched shear-resistant surface structure comprises multiple micro-arched units arranged in an array. Each micro-arched unit has a diameter of approximately 3-8 mm and a height of approximately 1-3 mm, and is hemispherical or semi-ellipsoidal in shape. The micro-arched units are arranged in a hexagonal array, similar to a honeycomb structure, with approximately 4-9 micro-arched units per square centimeter. Adjacent micro-arched units are connected by flexible connecting strips, allowing each unit to move independently in minute quantities within a certain range.

[0075] The micro-arched shear-resistant surface structure adopts a multi-layer composite structure design: the top layer is a micro-arched unit array layer, the middle layer is a flexible connecting network layer, and the bottom layer is a base layer connected to the air cushion body. The entire surface structure is fixed to the surface of the main air cushion 1 and the side air cushion 2 by thermo-press sealing or medical-grade adhesive.

[0076] The micro-arched shear-resistant surface structure is made of medical-grade silicone or TPU material.

[0077] The micro-arched anti-shear surface structure significantly reduces shear forces through the following mechanisms: when the patient moves, each micro-arched unit can independently undergo minute movement or deformation, rather than dragging the skin surface as a whole; lateral shear forces are distributed across thousands of independent units, with each unit bearing only a tiny portion of the force; the arched structure produces minute "rolling" or "flipping" deformations when subjected to lateral forces, transforming sliding friction into rolling friction and reducing the coefficient of friction; the micro-arched structure can redirect some of the shear forces parallel to the skin surface into vertical components, reducing lateral stress.

[0078] In this embodiment, the micro-arched anti-shear surface structure can fully cover the surface of the main air cushion 1 and / or the side air cushion 2, or can be selectively applied to high-pressure areas, such as the main air cushion 1 corresponding to areas prone to pressure sores, such as the sacrum and coccyx.

[0079] Optionally, in one embodiment, the intelligent pneumatic positioning care system further includes a control device for controlling the dual-purpose electric air pump to perform inflation and deflation operations at a preset time.

[0080] Optionally, in one embodiment, the intelligent pneumatic positioning care system further includes: an intelligent monitoring and control unit, a multi-functional sensor system, and a user interface, for achieving intelligent control by detecting the elderly person's posture and the pressure of the air cushion.

[0081] The intelligent monitoring and control unit includes a central processing unit (CPU), a memory, a signal processing module, and a communication module. The CPU is used to execute control algorithms and perform data analysis; the memory is used to store preset parameters, historical data, and personalized configurations; the signal processing module is used to process signals from sensors; and the communication module is used to exchange data with external devices (such as smartphones, nursing home monitoring systems, etc.).

[0082] The multi-functional sensor system includes: multiple pressure sensors located inside the main air cushion 1 and the side air cushion 2 for real-time monitoring of the air pressure inside each air cushion; a pressure distribution sensor array distributed on the upper surface of the main air cushion 1 for detecting human body pressure distribution and posture; an tilt sensor installed on the main air cushion 1 for measuring the tilt angle of the human upper body; and a proximity sensor located inside the side air cushion 2 for detecting the distance between the human body and the side air cushion 2.

[0083] The user interface includes a touch screen, indicator lights, and a voice prompt system, providing caregivers and users with convenient operation and status feedback.

[0084] In this embodiment, the workflow of the intelligent pneumatic positioning care system is as follows:

[0085] Initialization Phase: After the system is powered on, the intelligent monitoring and control unit automatically executes a self-test program to check the status of each air cushion, sensor, and valve. Simultaneously, the system reads the default configuration or previously used personalized settings from memory.

[0086] Intelligent detection phase: A multi-functional sensor system continuously monitors the human body's condition. A pressure distribution sensor array detects human posture; tilt sensors monitor upper body tilt; proximity sensors monitor the risk of side tilt; and pressure sensors monitor the air pressure inside each air cushion.

[0087] Automatic Adjustment Phase: Based on detection data, the intelligent monitoring and control unit can perform the following automatic adjustments: When a care need is detected (such as when a feeding time arrives or when a command is entered through the user interface), the system automatically starts the inflation program, controlling the dual-purpose electric air pump to inflate the side air cushion 2 according to a preset program, followed by inflating the main air cushion 1, until a suitable sitting angle is achieved; when the pressure distribution sensor array detects an improper human posture (such as side slipping or sliding), the system automatically adjusts the air pressure of the corresponding air cushion to correct the posture; when the tilt sensor detects that the upper body angle deviates from the preset value, the system adjusts the inflation level of the main air cushion 1; when the proximity sensor detects an abnormal distance between the human body and the side air cushion 2, the system increases the air pressure of the corresponding side air cushion 2 to provide better lateral support.

[0088] The intelligent safety protection mechanisms include: overpressure protection, when the pressure sensor detects that the pressure inside the air cushion is close to the safety threshold, the system will automatically limit further inflation or open the overpressure protection valve; abnormal posture alarm, when a dangerous posture (such as severe tilting) is detected, the system will issue an alarm and notify the caregiver through the communication module; and timed decompression function, the system can automatically adjust the air cushion pressure slightly after a preset time period to prevent the risk of pressure sores caused by maintaining the same posture for a long time.

[0089] Personalized learning function: The intelligent monitoring and control unit has machine learning capabilities, which can progressively optimize inflation parameters and adjustment strategies based on the user's body shape, preferred posture, and usage habits. For example, the system records the user's preferred sitting angle and automatically adjusts it to the most comfortable angle in subsequent use. This personalized data is stored in memory, allowing for the creation of independent profiles for multiple users.

[0090] Remote monitoring and control function: Through the communication module, the intelligent pneumatic positioning care system can connect to a smartphone application or the monitoring system of a medical care center to achieve remote status monitoring and control. Caregivers can view the user's posture, air cushion pressure, and other information through the application without entering the room, and can remotely adjust relevant parameters or initiate specific programs.

[0091] Scheduled task mode: Caregivers can set scheduled tasks through the user interface, such as automatically executing a sitting procedure at a fixed time (such as mealtime) or a lying-down procedure when it is time to sleep, based on the user's daily routine.

[0092] The intelligent monitoring and control unit is connected to the electric air pump (both charging and pumping) via a control circuit to control its working status; each sensor of the multi-functional sensor system is connected to the signal processing module of the intelligent monitoring and control unit via signal lines to transmit detection data; the user interface is connected to the intelligent monitoring and control unit via an interface connection line to receive user commands and display system status.

[0093] This intelligent implementation integrates sensor technology and intelligent control algorithms, enabling the intelligent pneumatic positioning care system to automatically adjust the inflation and deflation program according to the actual condition of the elderly, improving safety and comfort while reducing the burden on caregivers. It is particularly suitable for long-term care and home care scenarios.

The exhaust port is connected to the main air cushion gas. When the exhaust port is in the open state, the gas in the main air cushion is discharged through the exhaust port. When the external air source inflates the main air cushion through the air inlet, the one-way valve is initially closed, and the two side air cushions inflate before the main air cushion. As the air pressure in the two side air cushions gradually increases, when the pressure difference between the two side air cushions and the main air cushion reaches the opening pressure, the one-way valve opens, and gas enters the main air cushion from the two side air cushions through the one-way valve, thereby inflating the main air cushion. The exhaust port is not directly connected to the gas in the two side air cushions; the exhaust port is connected to a vacuum pump, which is used to extract air during the exhaust phase, creating a negative pressure in the main air cushion, so that the difference between the air pressure in the two side air cushions and the air pressure in the main air cushion is greater than the opening pressure, thereby opening the one-way valve to exhaust the gas in the two side air cushions. A support channel is provided between the exhaust port and the one-way valve to maintain gas communication between the main air cushion and the one-way valve even when the gas in the main air cushion is evacuated. This allows the external negative pressure generated by the vacuum pump to be transmitted to the main air cushion side of the one-way valve through the exhaust port, so that the gas in the two side air cushions can enter the main air cushion through the one-way valve and eventually be discharged.

2. The intelligent pneumatic positioning nursing system as described in claim 1, characterized in that, When the exhaust port is opened, the one-way valve is initially closed, and the gas in the main air cushion is released through the exhaust port before the two side air cushions. As the air pressure of the main air cushion continuously decreases, when the difference between the air pressure of the two side air cushions and the air pressure of the main air cushion exceeds the opening pressure, the one-way valve opens, and the gas from the two side air cushions enters the main air cushion through the one-way valve and is finally discharged to the outside through the exhaust port.
