Description

An anti-decubitus air mattress

technical field

The utility model belongs to the technical field of air mattresses, in particular to an air mattress for preventing bedsores.

Background technique

Decubitus ulcers are tissue ulceration and necrosis caused by persistent ischemia, hypoxia, and malnutrition due to long-term compression of local tissues. Skin pressure ulcer is a common problem in rehabilitation treatment and nursing. According to relevant literature reports, about 60,000 people die of bedsore complications every year. The most common cause of pressure ulcers is sustained vertical pressure on local tissues, especially in the bony bony bulges of the body. Generally speaking, the pressure that the blood vessels under the skin can withstand is about 32 mmHg. If the pressure exceeds the above pressure, the local blood vessels may be distorted and deformed, which will affect the passage of blood flow, and there will be ischemia. Decubitus ulcers are caused when a part of the body is subjected to more pressure than normal capillaries for a long time.

In response to the above problems, there are many types of air mattresses on the market for preventing bedsores. However, after investigation, it was found that the air bags of the existing air mattresses are all cylindrical. It is beneficial to the circulation of air between the person and the air mattress, and is not conducive to preventing the occurrence of bedsores; and the existing air mattress, which uses two groups of airbags to inflate and deflate in cycles to massage the patient, the actual massage effect is not good. Well, only half of the airbags support the patient during the massage, which increases the pressure between the patient and the mattress, makes the patient feel uncomfortable, and cannot promote the patient's blood circulation well.
