[0002] Pressure sores, also known as pressure ulcers or bedsores, are caused by prolonged pressure on localized tissues, leading to circulatory disorders and neurological malnutrition, resulting in skin necrosis and ulceration, and loss of normal function. In the early stages, the pressure area presents with localized redness and swelling that does not blanch when pressed. In the later stages, there may be full-thickness skin loss, with exposed bones, tendons, and muscles. Most pressure sores occur on bony protrusions that are subject to compression and shear forces, such as the sacrum, coccyx, ischial tuberosity, greater trochanter of the femur, elbows, knees, and heels.

[0003] After searching, Chinese patent CN214806234U discloses a nursing pad that can prevent pressure sores, including a nursing pad body, a fixing mechanism, an adjustment mechanism and a press module.
