Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical protection, in particular to a device for preventing pressure injury after operation. BACKGROUND

[0002] After operation, patients usually need to lie in bed for a long time, which will produce vertical pressure. The main cause of injury caused by vertical pressure is that local tissues are subjected to continuous vertical pressure, especially at the protruding parts of the body's bony prominences. If the patient is in bed for a long time or sits in a wheelchair, the inner lining pad is placed improperly, the plaster is not flat or has debris, and the local area is subjected to pressure exceeding the normal capillary for a long time, pressure injury can occur. Pressure injury can manifest as intact skin or open ulcer, 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 can be affected by the microenvironment, perfusion, comorbidities, and soft tissue conditions. In order to prevent postoperative pressure injury, a device for preventing postoperative pressure injury is needed. However, the commonly used devices for preventing postoperative pressure injury have limited injury prevention effect, require a large amount of manpower assistance, and have slow blood circulation at the contact part of the patient, which can cause numbness. In addition, the ventilation is limited, and in summer, the feeling of stuffiness will occur.
