Description

Technical Field

[0001] This utility model relates to the field of nursing equipment technology, and in particular to an anti-pressure ulcer device for intensive care. Background Technology

[0002] Pressure ulcers, also known as pressure sores or bedsores, are caused by prolonged pressure on local tissues, leading to continuous ischemia, hypoxia, malnutrition, and tissue necrosis. Skin pressure ulcers are a common problem in rehabilitation and nursing care. For critically ill patients who are bedridden for a long time, turning over is difficult, making them very susceptible to pressure ulcers.

[0003] A search of Chinese Patent Publication No. CN213911022U reveals a pressure ulcer prevention device for intensive care unit nursing. The device includes a base plate with a soft sleeve on its upper surface. An air bladder is located inside the soft sleeve, and an air inlet device is located at one end of the air bladder. A sterile pad is placed on the upper surface of the soft sleeve. Slots are provided on both sides of the base plate, and fastening bolts are threaded to the top of the slots. One end of the fastening bolts is movably connected to a compression plate via a rotating shaft. Through the air bladder and air inlet device, the air bladder is inflated during use. The patient lies on it, the sealing head is opened, and the gas inside the air bladder in contact with the wound is expelled through the air inlet, preventing pressure on the wound and thus preventing pressure ulcers.

[0004] However, the gap between two adjacent airbags is small and the airbags have poor air permeability, making it difficult to expel moisture from under the body in a timely manner. Prolonged exposure to a humid environment may cause pressure sores. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a pressure ulcer prevention device for intensive care includes a base plate 1. Fixing components are provided at the four corners of the base plate 1. The fixing components include several straps 101. The straps 101 are fixedly connected to the side wall of the base plate 1 and distributed at the four corners of the base plate 1. The base plate 1 is fixed to the nursing bed by the straps 101.

[0027] The top of the base plate 1 is provided with several first support components and second support components. The second support components are arranged between two adjacent sets of first support components. The first support component includes two first vertical plates 202. A first airbag 203 is fixedly connected between the two first vertical plates 202. The top of the first airbag 203 extends out of the first vertical plate 202. A first air inlet pipe 205 is fixedly connected to the rear side of the first airbag 203. The first air inlet pipe 205 communicates with the first airbag 203. A pressure relief valve is provided on the front side of the first airbag 203.

[0028] The second support assembly includes two second vertical plates 302, and a second airbag 303 is fixedly connected between the two second vertical plates 302. The top of the second airbag 303 extends out of the second vertical plates 302. A second air inlet pipe 305 is fixedly connected to the front side of the second airbag 303. The second air inlet pipe 305 communicates with the second airbag 303. A pressure relief valve is provided on the rear side of the second airbag 303.

[0029] Two sets of air supply components are symmetrically arranged at the front and back of the base plate 1. The air supply components include several fixed plates 401 fixedly connected to the front or rear side of the base plate 1. Air pipes 402 are fixedly connected between the fixed plates 401. Air supply pipes 403 are fixedly connected to the bottom of the air pipes 402. The other end of the air supply pipes 403 is connected to an air pump. The air pump is fixed on the nursing bed. The first air inlet pipe 205 and the second air inlet pipe 305 are respectively connected to different air pipes 402.

[0030] The periphery of the first airbag 203 extending out of the first vertical plate 202 is corrugated, and the periphery of the second airbag 303 extending out of the second vertical plate 302 is corrugated.

[0031] An auxiliary component is provided between the first support component and the second support component. The auxiliary component includes a converging cavity 501, which is located inside the base plate 1. The top of the base plate 1 has several air extraction holes 502 that communicate with the converging cavity 501. An air extraction pipe 503 that communicates with the converging cavity 501 is fixedly connected to one side of the base plate 1. An exhaust fan 504 is fixedly connected to the other end of the exhaust pipe 503. The exhaust fan 504 is fixed to the nursing bed.

[0032] The first vertical plate 202 and the second vertical plate 302 are both hinged to the top of the base plate 1, and a torsion spring is provided between the first vertical plate 202, the second vertical plate 302 and the base plate 1. A first limiting plate 204 is fixedly connected to the top of the base plate 1. The first limiting plate 204 is located on the side where the two first vertical plates 202 are far apart from each other. A second limiting plate 304 is fixedly connected to the top of the base plate 1. The second limiting plate 304 is located on the side where the two second vertical plates 302 are far apart from each other. The rotation angle of the first vertical plate 202 is limited by the first limiting plate 204, and the rotation angle of the second vertical plate 302 is limited by the second limiting plate 304.

[0033] Working Principle: During use, the base plate 1 is fixed to the nursing bed using straps 101. An air pump alternately inflates the first airbag 203 and the second airbag 303. When the first airbag 203 inflates, the pressure relief valve is opened to release the air from the second airbag 303, allowing the part of the body in contact with the second airbag 303 to leak out. Conversely, when the second airbag 303 inflates, the pressure relief valve is opened to release the air from the first airbag 203, allowing the part of the body in contact with the first airbag 203 to leak out. This alternating support from the first and second airbags 203 prevents prolonged contact between the body and either airbag 203 or the second airbag 303, which could cause sweating and a damp mattress. Simultaneously, the exhaust fan 504 is activated to remove moisture from the area in contact with the mattress through the exhaust port 502, preventing pressure sores or worsening of existing pressure sores due to prolonged exposure to a damp environment. When the first airbag 203 deflates… When the two first vertical plates 202 lose the compression of the first airbag 203, they rotate towards each other under the action of the torsion spring, making the two first vertical plates 202 form a V-shape with their openings facing downwards. This causes the gap between the two adjacent first vertical plates 202 and the second vertical plate 302 in the adjacent first support assembly and the second support assembly to gradually decrease as the distance from the base plate 1 decreases, increasing the wind speed. When the second airbag 303 deflates, the two second vertical plates 302 lose the compression of the second airbag 303 and rotate towards each other under the action of the torsion spring, making the two second vertical plates 302 form a V-shape with their openings facing downwards. This causes the gap between the two adjacent first support assembly and the second support assembly to gradually decrease as the distance from the base plate 1 decreases, increasing the wind speed and improving the dehumidification efficiency. After inflation, the first vertical plate 202 is squeezed open by the first airbag 203, and the second vertical plate 302 is squeezed open by the second airbag 303.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
