Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with accompanying drawing, as figure 1 , 2 Shown: the transparent waterproof dressing of the present invention, comprising a wound contact layer 1, a porous foam pad 2 and a breathable film 3, wherein the porous foam pad 2 has honeycomb-shaped mesh openings for timely viewing without changing the dressing The surface of the wound site and its surrounding skin; the contact surface of the dressing with the wound and the skin is coated with an acrylic glue adhesive, and contains active substances that promote wound healing on the contact surface.

[0019] Wherein, the mesh opening of the porous foam pad 2 is hexagonal, square, circular or other shapes; the active substance in the wound base layer has sterilization and / or antibacterial effect, so as to promote the healing of the wound; the waterproof dressing as a whole can be It is elastically deformed and closely fits the wounds of different parts of ...

Abstract

The invention provides a transparent waterproof dressing. The waterproof dressing is composed of a wound contact layer, a porous foam pad and a breathable film. The breathable film can prevent liquidand bacteria from permeating and prevent the wound from being polluted by the outside; due to the net-shaped design of the porous foam pad, the wound part and the surrounding skin of the wound part can be directly checked under the condition that the dressing is not replaced; and the surface of the dressing in contact with the wound and the skin is coated with an adhesive. The dressing is used foracute wounds with seepage levels from low to medium, such as postoperative wounds, wounds, small incisions, abrasion, scratching or cutting, puncture wounds, tearing wounds and first-degree or shallow second-degree burns and scalds.

Description

technical field [0001] The invention belongs to the technical field of passive medical devices, and in particular relates to a transparent waterproof dressing. Background technique [0002] Since the 1960s, clothes made of polyvinyl chloride, neoprene and various synthetic rubber-coated fabrics, used in harsh environments, have been widely welcomed due to their advantages such as waterproof and windproof. But they have a big shortcoming, that is, the sweat produced by the human body's own metabolism cannot be excreted in time, which makes people feel uncomfortable such as hot and cold. At the same time, the accumulated sweat provides a living environment for bacteria or fungal spores, etc., resulting in stains on the surface of the material, and serious degradation of the material, which is mainly due to the lack of "breathability" of the polymer film and coating at that time. of. In order to solve this problem, researchers from various countries began to pay attention to ...
