[0032] Such as Figures 1 to 4As shown, an embodiment of the present utility model provides a pressure ulcer prevention cushion, which includes a bottom plate 1, an adjustable top plate 3 and an adjustment component 4. A plurality of reinforcing rods 11 are arranged on the top of the bottom plate 1, and a sliding sleeve plate 2 is arranged on the top of the reinforcing rods 11. The adjustable top plate 3 is slidably sleeved inside the sliding sleeve plate 2. A plurality of grooves 9 are arranged inside the adjustable top plate 3. The adjustment component 4 includes an elastic pressing plate 401, which is arranged on the top of the bottom plate 1. A first weakening groove 404 is arranged on the inner wall of the elastic pressing plate 401. One end of the elastic pressing plate 401 is provided with a connecting plate 402, and one end of the connecting plate 402 is provided with an annular cushion plate 403. The annular cushion plate 403 is slidably sleeved inside the groove 9. An arc-shaped pressing plate 405 is arranged on the outer wall of the elastic pressing plate 401. One end of the arc-shaped pressing plate 405 is connected to the bottom of the adjustable top plate 3. A second weakening groove 406 is arranged on the inner wall of the arc-shaped pressing plate 405. The elastic pressing plate 401 is an arc-shaped curved surface elastic structure. The first weakening groove 404 is arranged in the middle of the elastic pressing plate 401. The elastic pressing plate 401 and the connecting plate 402 are of an integral structure. The elastic pressing plate 401 and the connecting plate 402 are made of rubber material. The elastic pressing plate 401 and the connecting plate 402 are linearly arranged and distributed at the bottom of the annular cushion plate 403. The arc-shaped pressing plate 405 is an arc-shaped curved surface elastic structure. The second weakening groove 406 is arranged in the middle of the arc-shaped pressing plate 405. The arc-shaped pressing plates 405 are linearly arranged and distributed at the bottom of the adjustable top plate 3.

The elastic pressing plate 401 and the connecting plate 402 are of an integral structure and are made of rubber material, having a certain elasticity. When the adjustable top plate 3 is pressed, under the action of the elastic pressing plate 401, the adjustable top plate 3 can be buffered, and the skin and tissue pressure caused by long-term sitting or lying can be relieved. At the same time, when the elastic pressing plate 401 is pressed, the elastic pressing plate 401 deforms outward, separating the two elastic pressing plates 401, which can ensure the air circulation between the two elastic pressing plates 401 and ensure the air circulation effect; the arc-shaped pressing plate 405 is arranged on the outer wall of the elastic pressing plate 401 and is linearly arranged and distributed at the bottom of the adjustable top plate 3. The elastic pressing plate 401 and the arc-shaped pressing plate 405 are of an integral structure. When the adjustable top plate 3 is pressed, under the action of the arc-shaped pressing plate 405, the adjustable top plate 3 can be initially buffered, and the skin and tissue pressure caused by long-term sitting or lying can be relieved. Not only can the elastic pressing plate 401 deform when the pressure ulcer prevention cushion is squeezed, and then the elastic pressing plates 401 are separated, ensuring that air can circulate between the two elastic pressing plates 401 and ensuring the ventilation effect of the pressure ulcer prevention cushion, but also when the body position is not often changed, the position where the pressure ulcer prevention cushion contacts the patient's skin can be adjusted, ensuring the air circulation between the pressure ulcer prevention cushion and the patient's skin, and at the same time avoiding problems such as the accumulation of sweat at the position where the pressure ulcer prevention cushion contacts the patient's skin, which affects the comfort of the patient during use.
[0033] AsFigure 3 and Figure 4 As shown in Figure 3 and Figure 4 , a limiting arc plate 407 is provided on the side wall of the elastic pressing plate 401. The limiting arc plate 407 is arranged between two elastic pressing plates 401. The limiting arc plate 407 is an arc-shaped curved surface elastic structure and is made of rubber. The elastic pressing plate 401 and the limiting arc plate 407 are an integral structure. By arranging the limiting arc plate 407 in the adjusting member 4, the limiting arc plate 407 is an arc-shaped elastic curved surface structure with a certain elasticity. The limiting arc plate 407 is arranged between two elastic pressing plates 401 and is linearly arranged. The elastic pressing plate 401 and the limiting arc plate 407 are an integral structure and are made of rubber. When the adjusting top plate 3 is squeezed, the deformation degree of the elastic pressing plate 401 can be limited, avoiding damage to the pressure ulcer prevention cushion caused by excessive deformation of the elastic pressing plate 401.
[0034] As Figure 3 shown in Figure 3 , a clamping plate 6 is provided at the bottom of the adjusting top plate 3, a limiting clamping block 7 is provided at the bottom of the clamping plate 6, a limiting clamping groove 5 adapted to the shape of the limiting clamping block 7 is provided in the sliding sleeve plate 2, a deformation groove 8 is provided on the inner wall of the clamping plate 6, and the limiting clamping grooves 5 are linearly arranged on the inner wall of the sliding sleeve plate 2. By providing the limiting clamping groove 5 and the limiting clamping block 7, the clamping plate 6 is an arc-shaped curved surface elastic structure. The limiting clamping block 7 is connected to the bottom of the adjusting top plate 3 through the clamping plate 6. The clamping plate 6, the limiting clamping block 7 and the adjusting top plate 3 are an integral structure. The shape of the limiting clamping groove 5 is adapted to the shape of the limiting clamping block 7. When it is necessary to adjust the position where the pressure ulcer prevention cushion contacts the patient's skin, by adjusting the position of the limiting clamping block 7 in the limiting clamping groove 5, the position of the adjusting top plate 3 in the sliding sleeve plate 2 can be adjusted, so that the annular cushion plate 403 protrudes in the groove 9, and then the position in contact with the patient's skin can be adjusted.
[0035] As Figure 1 and Figure 2 shown in Figure 1 and Figure 2 , a pressing dial plate 10 is provided on the outer wall of the adjusting top plate 3. The pressing dial plate 10 is a semi-circular structure. A plurality of anti-slip convex blocks 13 are provided at the bottom of the bottom plate 1. The anti-slip convex blocks 13 are hemispherical reinforcements and are made of rubber. By providing the anti-slip convex blocks 13, the anti-slip guarantee of the pressure ulcer prevention cushion can be realized, and it can be avoided that the position of the pressure ulcer prevention cushion slides during use, affecting the normal use of the pressure ulcer prevention cushion. A plurality of protective flaps 12 are provided at the top of the bottom plate 1. One end of the protective flap 12 is connected to the bottom of the sliding sleeve plate 2. By providing the protective flap 12, other items can be prevented from entering between the bottom plate 1 and the adjusting top plate 3, affecting the normal use of the pressure ulcer prevention cushion.
[0036] The working principle of the technical solution provided by the present utility model is as follows: When in use, let the patient sit on the pressure ulcer prevention cushion, so that the patient's skin contacts the top of the adjustment top plate 3. At this time, under the pressing of the patient's own weight, and at the same time under the action of the elastic pressing plate 401 and the arc pressing plate 405, the pressure on the skin and tissues caused by long-term sitting or lying can be relieved. Moreover, when the elastic pressing plate 401 is pressed, the elastic pressing plate 401 deforms outward, separating the two elastic pressing plates 401, which can ensure the air circulation between the two elastic pressing plates 401 and ensure the air circulation effect. Then, when it is necessary to adjust the position where the pressure ulcer prevention cushion contacts the patient's skin, by pushing down the pressing dial 10, the limiting block 7 moves downward and is clamped into another limiting card slot 5, so that the annular cushion plate 403 protrudes from the groove 9, and thus the position where the pressure ulcer prevention cushion contacts the patient's skin can be adjusted, avoiding problems such as the accumulation of sweat at the position where the pressure ulcer prevention cushion contacts the patient's skin and affecting the comfort of the patient during use, and at the same time ensuring the air circulation between the pressure ulcer prevention cushion and the patient's skin.
