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 on the bed with the human body, the body and the mattress are attached to form a closed state, 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.

② The multi-tube airbags of the multi-tube air mattress can be automatically controlled, alternately inflated, and change the pressure-bearing position of the bedridden body. However, because the bed surface airbags are divided into small airbags, each airbag is small and the inflation volume is limited. Adults Generally, the weight is larger, especially the hip position, and the higher pressure can lift the human body, change the position (point) of the human body, and achieve the effect of assisting in the prevention of pressure ulcers. However, due to the high inflation pressure, the airbag becomes rigid, and the junction of two adjacent airbags is not in contact with the user's body during use, resulting in uneven force on the user and poor user 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. At the same time, the common inflatable beds on the market all require a large inflation pressure to lift the user. At the same time, they need to use a complex control system to control and control the amount of inflation, which is expensive. User discomfort and prolonged bed rest can cause pressure sores.
