Compression negative pressure vacuum system

Abstract

The invention discloses a compression negative pressure vacuum system which comprises a compression foam material layer and a viscose pasting film, wherein the periphery of the viscose pasting film extends outward and out of the range of the compression foam material to form a pasting wing which can be pasted on the outer surface of the fixing position; after the pasting wing is pasted at the fixing position, a first adsorption cavity is formed among the inner surface of the pasting wing, the outer side surface of the compression foam material layer and the outer surface of the fixing position; the volume of the first adsorption cavity is increased along with the expansion of the compression foam material layer after liquid absorption, and local vacuum is formed; and the local vacuum of the compression foam material layer generates a long-time continuous negative-pressure suction effect on the wound and the deep soft tissues thereof so as to realize the effects of gradually diminishing the wound swelling and promoting local blood circulation. Similarly, the local vacuum of the compression foam material layer generates a negative-pressure suction effect on the surface needing dirt removal and the deep soft tissues thereof so as to gradually discharge the deep dirt. Moreover, negative pressure can be generated without an external negative pressure source, and the effects of vacuum exudate adsorption and deep dirt removal are realized.

Description

technical field [0001] The invention relates to an adsorption system, in particular to a compression negative pressure vacuum system. Background technique [0002] Due to the development of industry now, there are more and more particles in the air, and some tiny dusts are hidden in the skin on the surface of the human body to form dirt. The dirt on the surface of the skin can be removed by taking a bath, but the dirt on the deep layer of the skin cannot be removed by taking a bath. Modern people try to use chemical substances such as cleaning fluids and cleaning patches with chemical substances to clean up the dirt in the deep layer of the skin. Although the dirt in the deep layer of the skin has been cleaned to a certain extent, the remaining chemicals will affect the skin. [0003] There is also wound care. The wound is usually protected with a wound dressing. Wound plasters are generally medical polyurethane (PU) wound plasters. The medical polyurethane (PU) wound pla...

Problems solved by technology

However, when a large area of ​​wound or wound exudates, since the wound plaster cannot absorb liquid, its exudate remains on the surface of the wound or wound, which is not conducive to wound or wound healing on the one hand, and on the other hand forms a focus of bacterial growth

In addition, there are some negative pressure adsorption bandages, which can absorb the exudate on the wound surface and suck out the necrotic tissue deep in the wound. However, these bandages need an external negative pressure source to absorb the exudate from the wound.
