Mattress capable of preventing pressure sores

Abstract

The invention discloses a mattress capable of preventing pressure sores. The mattress comprises a mattress body, wherein a capsule body made of rubber is disposed on the upper surface of the mattress body; a film made of a waterproof and breathable material is disposed on the inner wall of the capsule body; the capsule body is filled with water; vent holes are formed in the capsule body wall; a repeatedly bent self-oscillation flow heat pipe is disposed inside the mattress body near the upper surface; an evaporator is disposed on one side of the self-oscillation flow heat pipe, and a condenser is disposed on the other side; multiple cavity-shaped net frames are disposed inside the self-oscillation flow heat pipe along the pipeline extending direction; and fixed particles are disposed in the net frame. The mattress capable of preventing the pressure sores with the structure has the advantages of the simple structure, low cost, good heat dissipation effects and good massage functions.

Description

technical field [0001] The invention relates to an anti-pressure sore mattress. Background technique [0002] Bed sores are also known as pressure sores. Pressure ulcers are caused by long-term pressure on local tissues, resulting in continuous ischemia, hypoxia, and malnutrition, resulting in tissue ulceration and necrosis. Skin decubitus is a common problem in rehabilitation treatment and nursing. According to relevant literature reports, about 60,000 people die of decubitus complications every year. [0003] The local tissue is compressed, and the capillary blood flow is compressed, resulting in tissue ischemia and hypoxemia. The decompressed blood flows back into the tissue, and the compressed area becomes congested, a phenomenon called reactive hyperemia. The cause is local redness that is prominent and the body supplies oxygen to ischemic tissues. The protective mechanism of local vasodilation is the response to the natural compensation of short-term ischemia. Imp...

AI Technical Summary

Problems solved by technology

[0005] For long-term bedridden patients, the key to preventing decubitus ulcers is to activate blood circulation and cool down the oppressed tissues of the patient. At present, mattresses with heat dissipation and massage functions are often used to solve the above problems, so that the body’s compressed state can be relieved. 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
