Description

Airbag, air bed and air bed system

The present invention relates to an air bag. More specifically, the present invention relates to an air bed having an air bag and an air bed system.

Because of the anti-acne effect, the air bed has been widely used in medical treatment for special patients, such as patients with large wounds and not suitable for turning over. A medical air bed includes a plurality of side air cells, an air pump, and a control valve device. Each balloon is typically a tubular body. Under the operation of the pneumatic pump and the control valve device, the airbags of the air bed alternately circulate and charge and deflate, and the surface of the air bed is dynamically changed. Therefore, the pressure on the surface of the patient's skin is alternately released, thereby reducing the incidence of acne in the patient.

However, when patients who are inconvenient to turn over are lying on a conventional air bed for a long time, even if these air bags are alternately circulated and deflated, the material impermeability of these air bags still causes contact with the patient during the period of contact with the patient. The humidity and temperature between these balloons and the patient increase. As a result, the patient still feels uncomfortable and can even develop acne.

U.S. Patent No. 7,409,735 discloses a dynamic cellular person support surface. In U.S. Patent No. 7,409,735, the support surface includes a plurality of inflatable members, wherein the inflatable members adjust the contact between the patient and the support surface by inflation and deflation. In particular, as shown in Figure 8 of that patent, the inflatable member has an upper surface. And the upper surface is made of a gas permeable material, which can provide an opening for the pressurized gas in the inflatable element to flow upward to solve the discomfort of the body by the air flow.
