Foot pillow for preventing pressure injury

Abstract

The invention discloses a foot pillow for preventing pressure injury. The foot pillow can keep heel of a patient suspended, reduce pressure on a lower edge of ankle, avoid pressure injury, and preventor treat walking inconvenience and the like caused by foot drop due to extensospasm of a stroke patient. The foot pillow comprises a pillow body, wherein a leg supporting part, a heel suspension groove and a limiting mechanism for preventing foot drop are arranged on the pillow body, the heel suspension groove is sunken downwards, the leg supporting part and the limiting mechanism are located ontwo sides of the heel suspension groove respectively, the leg supporting part is provided with an arc-shaped concave part used for being attached to leg, the arc-shaped concave part is in smooth transition connection with the heel suspension groove, and a pressure reducing mechanism used for reducing pressure at the ankle is arranged at a joint of the arc-shaped concave part and the heel suspension groove; the limiting mechanism comprises an abutting structure used for abutting against foot sole and a sliding structure used for sliding of the abutting structure, and the abutting structure is provided with a driving device.

Description

technical field [0001] The invention relates to the field of medical care products, in particular to a foot pillow for preventing pressure injuries. Background technique [0002] Pressure injury is due to long-term pressure on local tissues, resulting in persistent ischemia, hypoxia, and malnutrition, resulting in tissue ulceration and necrosis. According to relevant literature reports, about 60,000 people die of pressure injury syndrome every year. Pressure injuries mostly occur at bony prominences without muscle wrap or thin muscle layer, lack of adipose tissue protection and often under pressure, such as occipital tuberosity, scapula, elbow, vertebral prominence, sacrum, heel and other parts. [0003] For patients with stroke, the elderly, and those with spinal cord injuries who need to stay in bed for a long time, due to blood circulation disorders, decreased sensory ability, etc., pressure injuries are very likely to occur when local tissues are compressed.
