The working principle is as follows: when in use, the medical PVA cotton 1 has excellent biocompatibility, no toxicity and harmlessness to tissues, good mechanical property, good elasticity and soft and porous whole body, can well control and absorb wound surface seepage and prevent bacteria from invading and inhibiting bacteria, and has excellent water permeability, filtration and air permeability, thereby ensuring the uniform distribution of negative pressure on the wound surface, simultaneously the effusion drainage tube 2 and the effusion drainage hole 3 can quickly absorb the seepage on the surface of the wound surface completely through high negative pressure and transmit the seepage to the outside, and simultaneously a user can transmit 50 to 70 percent of liquid sugar to the surface of the wound surface through the sugar liquid transmission tube 4 to apply on an infected wound surface, thereby quickly controlling infection, thoroughly eliminating pus and necrotic tissues, promoting the growth of granulation tissues and the growth of epithelial cells, and simultaneously applying the medical PVA cotton on a larger wound surface, can quickly control infection, reduce the wound surface, create conditions for the second-stage operation, if the flow and time of liquid sugar need to be controlled, a user rotates the rotary handle 94 at the same time to drive the threaded rod 91 to rotate, then the threaded rod 91 rotates and moves to the left in the threaded sleeve, meanwhile the threaded rod 91 drives the extrusion plate 92 to move to the left under the assistance of a bearing, then the extrusion plate 92 extrudes the effusion drainage tube 2 and the sugar liquid conveying pipe 4, thereby controlling the flow and time of the liquid in the effusion drainage tube 2 and the sugar liquid conveying pipe 4, simultaneously adjusting the flow rate of the effusion drainage tube 2 to be slightly slower than the flow rate of the liquid sugar in the sugar liquid conveying pipe 4, ensuring that the wound surface is continuously perfused with the liquid sugar, absorbing the redundant liquid sugar lavage liquid while the effusion drainage holes 3 absorb the exudate, thereby realizing the dynamic circulation of the wound surface perfusion, further controlling and absorbing the seepage of the wound surface and preventing the invasion of bacteria and bacteriostasis.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
