Description

Temperature-adjustable ventilation mattress convenient for turning over

Technical Field

The utility model relates to a mattress field specifically is a ventilation mattress can adjust temperature convenient to stand up.

Background

Bedsore, also known as pressure ulcer, is caused by tissue ulceration and necrosis due to continuous ischemia, anoxia and malnutrition caused by long-term local tissue compression. Many paralyzed patients and those who are not convenient to move cause bedsores due to the excessive pressure of the local part in bed for a long time, and the common bedsore and high death rate cause high attention of various hospitals and related medical professionals. The disease is mainly caused by the fact that patients lying in bed for a long time have poor physical ability of actively moving the body, the body part is in contact with the bed surface for a long time, local moisture, blood is not circulated, red swelling, inflammation and ulceration occur, the main reasons are poor air permeability and air is not circulated, and an anti-bedsore inflatable mattress is basically used for preventing bedsore.

The mattress has double-layer air bags, a support body with movable massage, a turning-over body, a single-layer air bag and a single-layer toilet hole, and is made of air-tight and waterproof composite materials to form an air bag and a base fabric, and a bed surface is formed by a plurality of strip circular air bags because the air bags are air-tight.
