Description

Technical Field

[0001] The utility model relates to an intelligent pressure dispersion moisture-proof air cushion bed for long-term bedridden patients, belonging to the field of medical auxiliary facilities. Background Art

[0002] Patients who are bedridden for a long time are prone to pressure injuries because they cannot turn over on their own. Pressure injuries are caused by prolonged or excessive pressure on the skin and subcutaneous tissue, which leads to local blood circulation obstruction, tissue hypoxia and necrosis. This type of injury is common in patients who need to stay in bed for a long time, such as those recovering from surgery and paralyzed patients. When patients stay in bed or sit still for a long time, a part of the body will be under continuous pressure, resulting in obstruction of blood circulation, which in turn causes damage to the skin and underlying tissues. If the bedsore area is also moist, bacteria and fungi are more likely to breed, increasing the risk of infection.

[0003] Although there are many products such as anti-pressure sore pads, such as an anti-pressure sore bed and anti-pressure sore method with application number 202211215340.7, which automatically adjusts the pressure on body parts by inflating and deflating the airbag to prevent the occurrence of pressure sores. However, the existing anti-pressure sore beds cannot effectively solve the risk of infection caused by the continuous moisture of the patient's bedsore area. Existing studies have shown that when the humidity on the skin surface exceeds 60%, the natural barrier function of the skin will be damaged, making the skin more susceptible to external irritation and infection. Excessive humidity may also cause the skin to soften and increase its risk of pressure damage. Therefore, when anti-pressure sore pads are used for clinical care, nursing staff often need to use mattresses and clothes with good hygroscopicity to keep the skin of long-term bedridden patients dry and clean. Although it can achieve a certain effect, in the process of changing mattresses and clothes, patients still need to be moved, and the friction or collision generated in this process may bring unnecessary risks to nursing work. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides an intelligent pressure-dispersing moisture-proof air mattress for long-term bedridden patients. The utility model can provide corresponding support pressure according to the physical condition of the bedridden patient, and the utility model can reduce the moisture level of the patient's pressure sore without moving the bedridden patient, keep the patient's skin dry and clean without affecting the patient's physical condition, and avoid unnecessary friction or collision during nursing work.

[0005] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: an intelligent pressure-dispersing moisture-proof air mattress for long-term bedridden patients, comprising at least an air pump for controlling the air mattress and an air mattress body, the air mattress body being composed of a plurality of air bags arranged side by side, wherein a ventilation tube is provided on one side of the air mattress body, and an opening is provided at each air bag on the other side of the air mattress body, the opening being sealed by a sealing strip, a strip pocket is provided on the upper side of the inner wall of the air bag, a water-absorbing pad for absorbing water vapor is placed in the strip pocket, an infrared camera and a skin temperature and humidity sensor for monitoring the patient's skin condition are arranged on the outer surface of the air bag, and a single-chip microcomputer is communicatively connected with the infrared camera, the skin temperature and humidity sensor and the air pump.

[0006] Furthermore, the upper surface of the airbag of the air mattress is made of breathable and waterproof fabric, and the breathable and waterproof fabric is a PU fabric.

[0007] Furthermore, the sealing strip is a tubular structure that is extended out of the airbag, and two folds are arranged on the sealing strip. Matching Velcro is arranged in the middle of the two folds on the back of the sealing strip and on the edge of the airbag, so that the sealing strip can be folded along the two folds and fixed to the edge of the airbag.

[0008] Furthermore, the diameter of the cylindrical structure of the sealing strip matches the diameter of the airbag and is greater than the width of the water-absorbing pad.

[0009] Furthermore, one end of the ventilation tube is connected to the airbag, and the other end of the ventilation tube is connected to the normally open end of the three-way ventilation valve, and the other two interfaces of the three-way ventilation valve are respectively connected to the air inlet pipe and the exhaust pipe of the air pump.

[0010] Furthermore, the three-way ventilation valve is communicatively connected with the single-chip microcomputer, and the three-way ventilation valve realizes airway switching according to the electrical signal sent by the single-chip microcomputer.

[0011] According to the above technical solution, the intelligent pressure dispersing moisture-proof air mattress for long-term bedridden patients provided by the utility model collects the water vapor generated by the patient through the cooperation of breathable waterproof fabric and water-absorbing pad, maintains the airbag pressure during inflation by using the sealing strip, and replaces the water-absorbing pad during deflation. The air mattress monitors the patient's body data through an infrared camera, skin temperature and humidity sensor. Compared with the prior art, the utility model has the following advantages:

[0012] (1) Because the upper surface of the airbag of the technical solution adopted by the utility model is a breathable and waterproof fabric, and the absorbent pad is located in the belt-shaped pocket under the breathable and waterproof fabric, there is no need to move the bedridden patient when replacing the absorbent pad. Therefore, the utility model can keep the patient's skin dry and clean without affecting the patient's physical condition, reduce the humidity on the patient's skin surface, avoid unnecessary friction or collision during nursing work, and further reduce the risk of pressure sores.

[0013] (2) Because the sealing strip in the technical solution adopted by the utility model is folded along two creases and then fixed to the edge of the airbag, when the airbag is inflated, the folded structure of the sealing strip maintains the airtightness of the airbag, thereby maintaining the support of the airbag; after the airbag is deflated, the sealing strip replaces the absorbent pad through the tubular structure. Therefore, the utility model can maintain the airbag pressure during inflation and replace the absorbent pad during deflation, thereby keeping the patient's skin dry and clean without affecting the patient's physical condition.

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited to the following embodiments.

[0020] In the technical solution provided by the utility model, an intelligent pressure dispersion moisture-proof air mattress for long-term bedridden patients at least includes an air pump for controlling the air mattress and an air mattress body, such as Figure 1 As shown, the air mattress body is composed of a plurality of air bags 1 arranged side by side, and the air bags 1 are connected by connecting fabrics 11 to form a complete air mattress body structure.

[0021] A ventilation pipe 2 is provided on one side of the air mattress body, one end of the ventilation pipe 2 is connected to the airbag 1, and the other end of the ventilation pipe 2 is connected to the normally open three-way ventilation valve 3. The other two interfaces of the three-way ventilation valve 3 are respectively connected to the air inlet pipe 31 and the exhaust pipe 32 of the air pump.

[0022] Each airbag 1 on the other side of the air mattress body is provided with an opening, which is sealed by a sealing strip 4. Figure 3As shown, the sealing strip 4 is a cylindrical structure 41 extended from the airbag 1, and two folds 42 are arranged on the sealing strip 4. The middle of the two folds 42 on the back of the sealing strip 4 and the edge of the airbag 1 are provided with matching Velcro 43, so that the sealing strip 4 is folded along the two folds 42 and fixed to the edge of the airbag 1. The diameter of the cylindrical structure 41 of the sealing strip 4 matches the diameter of the airbag 1 and is larger than the width of the water-absorbing pad 6.

[0023] The upper surface of the airbag 1 of the air mattress is a breathable and waterproof fabric, which is a PU fabric. Existing PU fabrics achieve waterproof and breathable effects by embedding a PU film in the fabric. Its working principle is based on the principle of capillary motion and the effect of the surface tension of water droplets. In the water vapor state, water molecules are very small and can penetrate to the other side of the fabric through the capillary tube; when the water vapor condenses into water droplets, due to the effect of the surface tension of the water droplets, the water molecules cannot smoothly break away from the water droplets and penetrate to the other side. Figure 2 As shown, a strip-shaped pocket 5 is provided on the upper side of the inner wall of the airbag 1, and a water-absorbing pad 6 for absorbing water vapor is placed in the strip-shaped pocket 5. The water-absorbing pad 6 absorbs water droplets, thereby achieving the function of dehumidification and exhaust. When this embodiment is used, it is measured that the humidity on the skin surface can be reduced to below 40%, reducing the risk of external stimulation and infection of the skin, and helping to maintain the hardness of the skin, avoiding friction and collision when replacing the nursing pad.

[0024] The outer surface of the airbag 1 is provided with an infrared camera 71 and a skin temperature and humidity sensor 72 for monitoring the patient's skin condition. Figure 4 In the circuit diagram shown, the single chip microcomputer is connected to the infrared camera 71 and the skin temperature and humidity sensor 72. The single chip microcomputer has preset temperature and humidity thresholds. When the signals sent by the infrared camera 71 and the skin temperature and humidity sensor exceed the thresholds, the single chip microcomputer sends an electrical signal to control the air pump and the three-way ventilation valve 3 to realize the inflation and deflation of the airbag 1, thereby achieving the purpose of intelligently dispersing pressure according to the patient's state.
