Silica gel vacuum sealing drainage dressing

Abstract

The invention provides a silica gel vacuum sealing drainage dressing, and belongs to the technical field of medical equipment. The silica gel vacuum sealing drainage dressing solves the technical problem that an existing silica gel vacuum sealing drainage dressing is poor in drainage effect. The silica gel vacuum sealing drainage dressing comprises a dressing body. A drainage structure which can discharge percolate under the effect of negative pressure is connected to the dressing body. The silica gel vacuum sealing drainage dressing is characterized in that the dressing body comprises a silica gel layer which can be attached to a human body, through holes are evenly distributed in the silica gel layer, a liquid storage and filter layer and an absorption structure are sequentially arranged on the silica gel layer, the liquid storage and filter layer has the storage and filter functions, and the absorption structure has the percolate absorption function. The silica gel vacuum sealing drainage dressing can be used for processing a small amount of percolate at a postoperative incision, the drainage effect is good, wounds can be prevented from bleeding, and the silica gel vacuum sealing drainage dressing has the advantages of accelerating wound healing, decreasing the number of dressing change times and saving resources.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to dressing materials, in particular to a silicone gel negative pressure sealing drainage dressing. Background technique [0002] Negative Pressure Wound Therapy (NPWT) is an advanced wound treatment developed in recent years. It mainly promotes the healing of the wound surface by applying a low negative pressure (generally -55mmHg to 175mmHg) to the wound. Specifically, negative pressure attracts the cell membrane, which can expand and distort it. The cell is considered damaged, and the information of damage is transmitted to the nucleus. Through signal conversion, it causes the cell to secrete pre-healing growth factors, including vascular proliferation factors, thereby stimulating tissue Produce more new blood vessels; in addition, negative pressure suction absorbs the exudate from the wound, helping to establish the liquid balance of the wound; and can also provide a mois...

AI Technical Summary

Problems solved by technology

[0005] Although the above technical solution has a certain drainage effect, the seal between the transmission layer and the wound is poor, the drainage efficiency is low during the negative pressure drainage process, and the drainage is not thorough enough, resulting in slow wound healing. It is easy to cause blockage in the medium, resulting in unsatisfactory drainage effect
