Air cushion bed for preventing bedsore

Abstract

The invention discloses an air cushion bed for preventing bedsore, which includes a body, an air pump, a control device and a plurality of electromagnetic valves. The air cushion bed is characterizedin that the air cushion bed also includes a membrane pressure sensor. The body includes an air cushion surface, an air cushion intermediate layer and two long strip air bags. The air cushion surface layer and the air cushion intermediate layer are composed of multiple rows of independent airbag straps side by side. Each of the airbag strap includes a plurality of independent block airbags; the membrane pressure sensor covers the upper surface of the air cushion surface layer. The membrane pressure sensor includes a flexible membrane and a plurality of pressure sensor units arranged on the flexible membrane. Each pressure sensor unit is in one-to-one correspondence with each block air bag on the surface layer of the air cushion. The air cushion bed has the advantages that: the air cushion bed can prevent the generation of bedsore, adjust the inflation degree of each position of the air cushion bed according to the pressure of each part of the human body, reduce the pressure of the bodysupport when the patient is in bed, and help the patient for whom it is difficult to change the body position independently turn over.

Description

technical field [0001] The invention relates to a nursing mattress, in particular to an anti-decubitus air mattress. Background technique [0002] According to statistics, there are currently about 450,000 long-term bedridden patients in my country. Cerebrovascular accidents, car accidents, traumatic fractures, etc. may lead to long-term bed rest. However, for bedridden patients, especially those who are bedridden for a long time and cannot change their positions independently, the local tissues of the body are under pressure due to long-term bed rest, and blood flow disorders are prone to occur in the local tissues under pressure, resulting in tissue ischemia, local inflammatory reactions and even external The invasion of pathogenic bacteria produces local infection, which causes tissue necrosis and produces bedsores. Bed sores are prone to occur in places that are under pressure and lack of adipose tissue protection, without muscle wrapping or at bony prominences with thi...

Problems solved by technology

Because decubitus ulcers often occur in places that are prone to compression such as skeletal bulges, the mattresses of bedridden patients are usually air mattresses. The lower air chamber can make the air cushion softer, fully in contact with the body, and more comfortable when sleeping. However, the shape of this air-cushion bed is fixed, and the position of each pressure support point after inflation is also fixed, and different patients have different physical conditions due to their different physical conditions. The support pressure required by the body is also different. Even for the same patient, the support pressure required by various parts of the body will often change due to the change of sleeping position during sleep. Therefore, it is difficult for the commonly used air mattress to keep the bedridden patient comfortable at all times. state, to ensure the quality of sleep
