Description

an air mattress

technical field

The utility model relates to the technical field of daily necessities, in particular to an air mattress.

Background technique

At present, with the aging of the population, many elderly people need to rest in bed at home, hospitals and nursing homes. The elderly are different in weight and thickness, and the bed body needs to be different in hardness and softness when sleeping. The common air mattresses on the market are: integral air mattresses , multi-tube air mattresses and pneumatic suspension beds, but the various products and structural designs commonly found in the market are that the human body lies directly on the air mattresses and sheets, and various inflatable mattresses have various problems in use:

① The contact position of the one-piece air mattress and the human body is relatively fixed. After lying in bed with the human body, the body and the mattress form a closed state after being attached, and the air permeability is poor. In addition, the change of the pressure-bearing point of the human body in bed is small, which cannot effectively reduce the effect of dispersing the pressure on the prone position of human pressure ulcers, and the effect of auxiliary prevention of pressure ulcers is limited.

②The multi-tube airbags of the multi-tube air mattress can be automatically controlled, alternately inflated to achieve the effect of changing the pressure and force of different positions of the bedridden body, but because the bed surface airbags are divided into small airbags, each airbag is small, and the inflation volume is small. It is limited. Adults are generally heavier, especially at the buttocks. Higher air pressure can lift the human body and change the position (point) of the weight of the human body to achieve the effect of assisting in the prevention of pressure ulcers. However, due to the high inflation pressure, the airbag becomes hard, and the two groups of airbags are alternately inflated and deflated to hold up the human body. The bedridden human body and the air cushion are in contact with the load-bearing position relatively concentrated, and the local pressure is increased. The long-term bedridden patient Poor experience.

③The pneumatic suspension bed is equipped with more than 100 structurally designed airbags on the bed surface, and the human body is lifted up by automatically controlling the inflation and extraction of high-pressure air flow of different groups of airbags, so as to achieve the goal of preventing pressure ulcers and treating wounds. However, the contact between the high-pressure airbag of the pneumatic suspension bed and the force point of the bedridden body cannot be predicted, which will cause the user to feel uncomfortable. At the same time, it must use a complete set of control systems, which is expensive. Currently, it is only suitable for the rescue and treatment of large-scale burns and scalds, and cannot be universally applied. in ordinary homes and nursing homes.

Due to the common anti-pressure sore air mattress on the market, the user directly contacts the inflatable air cushion through the sheet during use, because the inflatable airbags are made of non-breathable materials, and the bedridden has a poor feeling of use.
