Description

Technical Field

[0001] The utility model relates to a special heel protection device for patients with advanced tumors. Background Art

[0002] Pressure sores refer to long-term pressure on local tissues of the body, which leads to obstruction of local blood circulation and loss of normal skin function, thus causing local tissue damage and necrosis. Patients with advanced tumors have limited independent mobility or are bedridden for a long time, which makes them prone to pressure injuries. Traditional pressure sore prevention generally involves regular turning over and changing body position to promote blood circulation and reduce the time when bony protrusions are under pressure, but this is not only difficult to care for, but also difficult to prevent completely. In addition to the careful care of nursing staff, anti-pressure aids are often used to prevent pressure sores clinically. Currently, the tools used to prevent pressure sores clinically include: air mattresses, turning beds, cotton pads, rubber air rings, etc., but air mattresses and turning beds are expensive and have limited clinical application. If the rubber air ring is not placed properly, it may cause venous return to the air ring site to be blocked, causing edema of the tissue in the air ring, so it is no longer recommended for use. Although cotton pads are low in cost, they have uneven pressure distribution, poor air permeability, and moisture is not easy to dissipate. After a long period of use, the sponge in the pressure area loses its elasticity and cannot play a role in reducing pressure and preventing pressure sores. Summary of the invention
