Water-cushion air-cushion integrated anti-pressure-sores mattress

Abstract

The invention relates to a water-cushion air-cushion integrated anti-pressure-sores mattress. The mattress comprises an upper layer and a lower layer, the upper layer is provided with a closed inner cavity which can be filled with liquid, and the lower layer is provided with a plurality of independent closed chambers which can be filled with gas. The design has the advantages that the liquid has arelatively high specific heat capacity and can take away redundant heat, the gas has certain elasticity and relatively strong comfort, and the air inflation speed is much faster than the liquid filling speed, so that the posture of a user can be controlled indirectly through height change by adjusting the gas.

Description

technical field [0001] The invention relates to a bed care product, in particular to an anti-pressure sore mattress integrated with a water cushion and an air cushion that can be turned over at regular intervals. Background technique [0002] Pressure sores, or pressure ulcers, are localized tissue damage caused by pressure, friction, shear, and moisture. At present, the incidence of pressure sores is still high. According to relevant international survey reports, the overall prevalence of pressure sores is 5.6%-15.5%. Domestic surveys show that the incidence of hospital pressure sores is 3%-14%. Pressure ulcers can reduce the quality of life of patients and even cause death. [0003] The normal capillary pressure is 2.1kPa-4.3kPa. When the pressure beyond the capillary load range acts on the compressed local tissue, it can block the perfusion of the capillary to the compressed local tissue, causing the tissue cells to lack nutrients, blood and oxygen. When the local tiss...

Problems solved by technology

In actual use, due to the need for nurses to regularly implement the turning plan to achieve the preventive effect, the implementation is often not in place when human resources are in short supply, and the phenomenon that the turning angle is not in place is common.

On the other hand, for long-term bedridden patients, the key to preventing them from getting pressure sores is to make the blood flow unobstructed and dissipate heat in the compressed parts of the patient. At present, mattresses with heat dissipation and massage functions are often used to solve the above problems, so that the body is affected. The pressure state is relieved, and the skin is cool and comfortable, but the existing mattresses with heat dissipation and massage functions have the disadvantages of complex structure, high production cost, and poor heat dissipation and massage functions. If pressure sores have occurred, massage is not suitable
