Description

Technical Field

[0001] The invention relates to the technical field of medical protection, and in particular to a device for preventing postoperative pressure injuries. Background Art

[0002] After surgery, patients usually need to stay in bed for a long time, which will produce vertical pressure. The main reason for vertical pressure injury is that local tissues are subjected to continuous vertical pressure, especially on the protruding parts of the body bones. If you stay in bed or sit in a wheelchair for a long time, the padding in the splint is improperly placed, the plaster is uneven or has debris, and the local area is subjected to pressure exceeding normal capillaries for a long time, it can cause pressure injury. Pressure injury can manifest as intact skin or open ulcers, which may be accompanied by pain. The injury is caused by strong and / or persistent pressure or pressure combined with shear force. The tolerance of soft tissue to pressure and shear force may be affected by the microenvironment, perfusion, complications and soft tissue conditions. In order to prevent postoperative pressure injury, a postoperative pressure injury prevention device is needed. The common postoperative pressure injury prevention devices on the market have limited injury prevention effects and require greater human assistance. In addition, the blood circulation in the contact area of ​​the patient is slow, numbness is prone to occur, and the ventilation is limited, which will cause stuffiness in summer. In addition, the pillows in the hospital are of different heights and cannot meet the different height requirements of different patients. Summary of the invention
