Pull-out type negative pressure medical sponge stirring and scraping device

Abstract

The invention discloses a pull-out type negative pressure medical sponge stirring and scraping device. The pull-out type negative pressure medical sponge stirring and scraping device comprises a stirring and scraping combiner, a hollow medical sponge stick and a wide-edge suction disc, wherein the stirring and scraping combiner is arranged in the hollow medical sponge stick; the wide-edge suction disc is arranged above the hollow medical sponge stick in a matching way, and is provided with a medical sponge flushing port and a medical sponge negative pressure pipe joint; the stirring and scraping combiner comprises a sleeve cylinder mechanism and a scraper mechanism, and the scraper mechanism comprises a shaft rod, a propeller and a brush; the sleeve cylinder mechanism comprises a sleeve cylinder, a shaft hub, an air suction pipe connecting part and an air delivery pipe connecting part; each connecting part is provided with an air port and a thread joint, and is connected with the sleeve cylinder through the thread joint. The pull-out type negative pressure medical sponge stirring and scraping device has the advantages that the dirt attached onto the surface of the sponge can be scraped and sucked out, the blockage of medical sponge micro-channels is avoided, and the inflammation reaction of wounds is reduced; under the condition of not replacing a skin traction closer and a sponge, the dirt is flushed and cleaned; by matching with the skin traction closer, the skins at both sides of the wound can be gradually closed.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and in particular relates to a detachable negative-pressure medical sponge scraper applied to negative-pressure medical sponge drainage in the field of surgery, which is often used in conjunction with a skin stretch closure. Background technique [0002] In the field of surgery, the application of medical sponge negative pressure drainage technology is often involved. Because the gap between the foam particles of medical sponge is small, it is difficult to attract body fluid cell groups and impurities with large molecular weight from the wound. Under the action of negative pressure, It is easy to block the microchannels of the medical sponge, causing the wound to hide dirt and infection, especially for patients with pressure sores on the buttocks, even if the skin stretcher is used locally and the ordinary medical negative pressure sponge is used for filling, it will not cause infection...

AI Technical Summary

Problems solved by technology

[0003] In view of the above problems existing in the prior art, the object of the present invention is to provide a detachable negative pressure medical sponge scraper, which can scrape off the dirt attached to the surface of the sponge and suck it out, avoiding the blockage of the microchannel of the medical sponge , reduce the wound inflammatory response, and stimulate the growth of wound granulation, especially in the wound of pressure sores, without replacing the skin stretch closure and sponge, it can be washed and removed dirt, and at the same time, the skin stretch Under the action of tension, the tension of the antagonized sponge gradually gathers the skin on both sides of the wound.
