Negative pressure type drainage rehabilitation device for chronic wounds of old people

Abstract

The negative pressure type drainage rehabilitation device comprises a biological semi-permeable membrane, a dressing change assembly is installed in the middle of the top end of the biological semi-permeable membrane, a fixing ring adheres to the middle of the top end of the biological semi-permeable membrane, the inner side of the fixing ring is in threaded connection with a threaded disc, and the top end of the threaded disc is connected with a rotating block; a clamping groove is formed in the middle position of the inner side of the threaded disc, a sealing pressing plate is slidably embedded in the bottom position of the inner side of the fixing ring, the bottom end of the flow pipe is connected with a flow dividing box, the outer side of the flow dividing box is connected with a collecting and releasing pipe, and a circulating groove is formed in the bottom position of the outer side of the collecting and releasing pipe. The rotating block drives the threaded disc to rotate, medical staff quickly replace the medical sponge, the biological semi-permeable membrane does not need to be uncovered again and then pasted, discomfort of old patients is reduced, the application range of the negative pressure technology is widened, and the negative pressure rehabilitation effect is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a negative pressure drainage rehabilitation device for elderly chronic wounds. Background technique [0002] Negative pressure wound treatment technology is a new technology developed in recent years for the treatment of wounds. It uses bio-semipermeable membranes to seal open wounds, uses a special negative pressure machine to generate a certain negative pressure, and acts on the wound through drainage tubes and dressings. For wounds after debridement, studies have shown that this therapy can accelerate blood circulation at the wound site, significantly promote the entry of new blood vessels into the wound, stimulate the growth of granulation tissue, fully drain, reduce edema, reduce pollution, and inhibit bacterial growth, which can directly accelerate wound healing. Or to create conditions for surgical repair, it is an efficient, simple and economical pure physical t...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a negative pressure drainage rehabilitation device for elderly chronic wounds, which can effectively solve the problem that the existing negative pressure drainage equipment proposed in the above background technology is very troublesome to change dressings for the elderly, because the skin of the elderly is lacking. Elasticity makes it very difficult to remove the biological semipermeable membrane. The process of removing the semipermeable membrane is very painful for elderly patients, and the wound is in contact with air for a long time when changing the dressing, which easily induces wound infection and reduces the recovery speed. , the problem that the advantages of negative pressure drainage equipment cannot be fully utilized
