[0002] At present, the prevention methods of pressure injuries of critically ill patients in clinical practice at home and abroad are mostly limited to regular manual intervention to turn over, which leads to the problems of high labor intensity and low efficiency in nursing work, which also increases the time and economic cost of patients' disease recovery. For the care of pressure injuries, the most effective way is prevention. Through intelligent technical means, nursing staff can realize injury monitoring and pressure monitoring, so as to achieve early intervention, early prevention and early treatment, and avoid the occurrence of pressure injuries from the source. Most of the existing nursing mattresses are supine, and the patient's lying position cannot be automatically changed. When encountering patients with inconvenience in movement and unable to turn over and lie on their side by themselves, it is still necessary to set up additional caregivers to help patients turn over and lie on their side and change their positions regularly to prevent muscle atrophy and pressure injuries caused by lying in a fixed position for a long time, which is extremely inconvenient and increases the manpower burden. Patients who are bedridden for a long time and cannot change their body position independently are still very likely to suffer from long-term pressure on the local skin of the body during the long-term bed rest treatment course, which leads to the occurrence of pressure injuries, seriously affecting the treatment of patients. In order to alleviate the worries and pain of patients with limited mobility and long-term bedridden patients, and to reduce the workload of nursing staff, the research of related medical devices in the industry remains a key and difficult point.

Each airbag can automatically intake and exhaust air independently, so that each airbag can be individually controllable.

[0032] Each airbag is equipped with an independent pressure sensor 6, and the air pressure is collected by the controller 3. The touch screen 31 of the controller 3 displays the air pressure data obtained from the pressure sensor 6 in real time, so as to monitor the status of each airbag in real time. Then, the air pump is controlled to inhale or exhaust air to each airbag individually as needed.

[0033] The body position modes of the intelligently controlled multifunctional medical air cushion of the present invention include: (1) supine body position, by adjusting each airbag, the upper surfaces of the horizontal airbag area 11 and the lifting airbag area 12 are made flush. (2) back lifting body position, by adjusting each airbag, the upper surface of the lifting airbag area 12 is made higher than the upper surface of the horizontal airbag area 11, such as Figure 5As shown, the backrest is raised to achieve back lifting, which can provide a lifting angle of no more than 45°. The head, shoulders and heart of the individual are lifted relative to the lower body, while the lower body remains roughly aligned with the horizontal plane. (3) Lateral tilt position, by controlling the two square airbags in the lateral tilt airbag area 13, such as Figure 6 As shown, the left or right side back push is realized to achieve a body position with the left side tilted or the right side tilted, and the two side tilt square air bags can provide a side tilt angle of no more than 25°.

[0034] The intelligently controlled multifunctional medical air cushion of the present invention can be set to a static mode, in which all air bags are inflated.

[0035] The intelligently controlled multifunctional medical air cushion of the present invention can also be set to a dynamic mode, which includes a dynamic alternating mode for supine position and back lifting position, in which the odd-numbered airbags and even-numbered airbags in the horizontal airbag area and the lifting airbag area are alternately inflated and deflated in groups.

It is not only suitable for the treatment and nursing of various complications caused by long-term bed rest, realizing intelligent nursing and preventing pressure injuries, but can also be used for daily care and treatment. It utilizes physiological and dynamic principles and uses an air pump to inflate and deflate the air cushion to achieve the desired static or dynamic posture mode, thereby achieving daily care and treatment effects.

[0040] The electric air intake valve and the electric air exhaust valve of the present invention can adopt a 12V large-flow single air valve.

[0041] The air pump of the present invention can adopt a 220VAC large flow electromagnetic pump, and the specification can be 50L / M. The air pump adopts AC 220V, 50Hz power supply, and the air pump protection level is IP21.

[0042] The power supply of the present invention adopts a finished power module with 3C certification, 220VAC input, 12V output. Because multiple gas valves work at the same time, the power of the power module is more than 60W.

[0043] In one embodiment of the present invention, Figure 1 As shown, the controller may include: a touch screen 31, an emergency button 32, and a buzzer alarm light 33. The touch screen 31 displays the current pressure of each airbag, the operation of the air pump, the upper and lower limits of the required pressure of the airbag, the control of each intake valve and exhaust valve, and the operation control of various modes, including the odd-even alternation of the airbag, the reminder of the air pressure remaining unchanged for a long time, the left and right rollover control, the airbag pressure mode, etc. In the event of an emergency, the emergency button 32 can be pressed, the air cushion stays in the current state, the air pump stops working immediately, or all airbags start to exhaust. When the parameter exceeds the set standard value, the buzzer alarm light 33 will sound an alarm. Figure 1 The controller 3 shown in the figure has ventilation and heat dissipation functions on both sides, and handles are installed on both sides to facilitate the movement of the control cabinet at any time.

[0044] In the intelligently controlled multifunctional medical air cushion according to the present invention, each airbag may be provided with a manual deflation valve 7, and the manual deflation valve 7 is provided on the outer cover 2. The manual deflation valve 7 is preferably provided at the side end of the outer cover 2. Each airbag is provided with a manual deflation valve 7 that can be operated by one hand, and the manual deflation valve 7 may be provided with two gears of deflation and pressure maintenance. The functions of manual deflation and pressure maintenance are realized by the different positions of the knob, which is convenient for the operator to adjust the state of the airbag at any time in emergency or special circumstances.

[0045] Each airbag of the present invention can independently control air intake and exhaust, and the nursing staff can release pressure and maintain pressure on a specific airbag through the control interface of the controller 3 or the manual air release valve 7, thereby realizing static mode and dynamic alternating mode for different body positions, and effectively preventing complications caused by long-term bed rest, such as pressure injuries.

[0046] In the multifunctional medical air cushion with intelligent control according to the present invention, flexible sensors (not shown) are provided on the horizontal airbag area 11 and the lifting airbag area 12, and are electrically connected to the controller. The flexible sensors can be attached to any position of the upper surface (the surface in contact with the patient's body) of the airbags on the horizontal airbag area 11 and the lifting airbag area 12 as needed. Preferably, flexible sensors are provided at the parts that are prone to pressure injuries (i.e., large forces), such as the scapula, sacrum, heels, etc. More preferably, the upper surfaces of the airbags on the horizontal airbag area and the lifting airbag area are all covered with flexible sensors. The present invention monitors the vital sign data in real time by providing flexible sensors, including information such as pressure, temperature and humidity, and transmits the monitored data to the controller. The controller processes the monitored vital sign data and compares them with the standard threshold, and generates an alarm signal when the predetermined threshold is reached. Medical staff or patients can be reminded to adjust the patient's position in time according to the monitored signal to effectively prevent pressure injuries. Ultimately, the beneficial effects of reducing the difficulty of treatment and nursing, reducing the consumption of human resources, and improving the accuracy and effect of treatment and nursing are achieved.
