Background
At present, along with the aging of population, many old people need to lie in bed at home, in hospitals and in rest homes, the old people are different in fatness and thinness, the bed body required during sleeping is different in hardness, the common inflatable mattresses in the market are an integral inflatable mattress, a multi-tube inflatable mattress and a pneumatic suspension bed, but various common products and structural designs in the market at present are that a human body is directly laid on the inflatable mattress and the bed sheet, and various problems exist in the use of each inflatable mattress:
① The contact position of the integrated inflatable mattress and a human body is relatively fixed, and after the integrated inflatable mattress is used for lying in bed with the human body, the integrated inflatable mattress forms a closed state after being attached to the mattress, and the air permeability is poor. In addition, the pressure bearing points of the bedridden body of the human body have small change, the effect of dispersing pressure at the good positions of the pressure sores of the human body cannot be effectively reduced, and the auxiliary effect of preventing the pressure sores is limited.
② The multi-tube air bags of the multi-tube air mattress can be automatically controlled, alternately and alternately inflated to change the pressure-bearing and stress positions of the bedridden body, but because the air bags on the bed surface are divided into small air bags, each air bag is small, the inflation volume is limited, the general weight of an adult is large, especially the hip position, the human body can be supported by high pressure, and the riding position (point) of the human body is changed, so that the effect of assisting in preventing pressure sores is achieved. However, because the inflation pressure is high, the air bags are hard, and the junction of two adjacent air bags is not contacted with the body when the user uses the inflatable bag, so that the stress of the user is uneven, and the use experience is poor.
③ The pneumatic suspension bed is provided with more than 100 structural design air bags on the bed surface, and the human body is supported by automatically controlling the inflation and the air suction of high-pressure air flows of different air bags so as to achieve the aims of preventing pressure sores and treating wound surfaces. However, the contact between the high-pressure air bag of the pneumatic suspension bed and the stress points of the bedridden human body cannot be predicted to cause discomfort to the user, and meanwhile, the pneumatic suspension bed is expensive because a whole set of control system is needed, so that the pneumatic suspension bed is only suitable for rescuing treatment of large-area burns and scalds, and cannot be universally applied to ordinary families and nursing homes.
Because the common pressure sore prevention air cushion bed in the market, a user is in direct contact with the air cushion through the bed sheet in the use process, and because the air bags are made of airtight materials, the use feeling of the bedridden user is poor. Meanwhile, the common inflatable beds in the market all need larger inflation pressure to support a user, the inflation amount is controlled by using a complex control system and a sensor, the price is high, and meanwhile, the bed body is too hard due to the larger inflation pressure, so that the user is uncomfortable, and pressure sores are generated due to long-time bedridden.
