Description

Foam dressing

Technical Field

The utility model belongs to the technical field of medical sanitary dressing, especially, foam dressing.

Background

Traditional wound dressings, including dry gauze and oil gauze, dry gauze is used to cover the wound, but the exudate management capacity is limited, adhesion to the wound may cause re-injury of the new epithelial tissue; the oil gauze type dressing contains vaseline or triglyceride, and can prevent wound adhesion, but has poor ability to promote wound healing. Because the liquid secreted by the wound surface can not permeate the rubberized fabric layer, the traditional wound dressing is easy to cause the soaking of local skin, so that the wound and the surrounding skin are whitened and even rotten. Modern wound dressings, such as foam dressings, avoid the drawbacks of traditional wound dressings to a great extent, not only can comprehensively protect wounds, but also can promote wound healing. But the wound healing condition is difficult to observe by pasting the foam dressing, even if the foam dressing adopts a transparent backing layer material, the wound condition under the polyurethane sponge layer can be observed only by tearing the adhesive layer, and once the adhesive layer is torn, the dressing pasting effect is poor, and the wound surface of a patient is greatly influenced. Therefore, the development of a foam dressing which can facilitate the observation of the wound surface is an urgent problem to be solved by those skilled in the art.
