Description

Multifunctional foot pillow

Technical Field

The invention relates to the technical field of medical care products, in particular to a multifunctional foot pillow.

Background

The pressure injury is caused by tissue ulceration and necrosis due to continuous ischemia, anoxia and malnutrition caused by long-term local tissue compression. Pressure injury is a common problem in rehabilitation therapy and nursing, and occurs in bony prominences without muscle wrapping or with thin muscle layers, lack of protection of adipose tissues and frequent compression, such as occipital tuberosity, scapula, elbow, vertebral body prominence, sacral caudal portion, heel and the like.

For the patients who need to lie in bed for a long time, such as cerebral infarction patients, the old, paralysis patients, and the like, pressure injury is easy to occur when local tissues are pressed due to blood circulation disorder, decreased sensing ability and the like. The heel of the patient is in contact with the bed surface for a long time, so that the skin is seriously pressed, and the heel is a frequently-damaged part caused by pressure. The mode that makes the heel unsettled in patient's shank below is filled up to present clinical pillow commonly used prevents heel pressure nature damage, but because factors such as patient's restlessness, pillow support nature are poor for the heel is difficult to keep unsettled for a long time, thereby leads to the production of pressure nature damage.

In addition, the patient lies on the back for a long time, and the back and other parts are not breathable for a long time, so that skin diseases such as eczema, bedsore and the like are easy to occur.
