Visible waterproof dressing

Abstract

The invention discloses a visible waterproof dressing which is of a four-layer structure. The visible waterproof dressing sequentially comprises a backing, an absorbing layer, a wound contact layer and a release layer from top to bottom. The backing is a PE or PET covered transparent PU film, wherein the PU film is coated with a low-sensitivity acrylate adhesive; the absorbing layer is hollowed polyurethane foams or polyvinyl alcohol foams and is located in the middle of the face, coated with the adhesive, of the backing, and the area of the absorbing layer is smaller than that of the backing;the wound contact layer is made of a hollow silica gel material and has the same area as the absorbing layer, and the dressing has the same hollow type. The dressing has the good waterproof performance and breathability, and can conveniently check the wound healing condition at any time, the dressing and the wound are not likely to be adhered, and repeated wound tearing is avoided.

Description

technical field

[0001] The invention belongs to the field of medical devices, in particular to a medical dressing, in particular to a visible waterproof dressing. Background technique

[0002] Medical dressings are wound-wrapping supplies, medical materials used to cover sores, wounds or other damages. With the in-depth study of the pathophysiology of the wound healing process, people's understanding of the wound healing process has become more and more profound, which has led to the continuous improvement and development of medical wound dressings. Medical dressings have become one of the standing medicines in daily life. They are often used in emergency care when minor trauma occurs, to stop bleeding and disinfect and protect wounds, while isolating bacterial contamination in the environment. Common dressings usually consist of a release layer, an adhesive layer, an isolation layer, and a protective layer. The adhesive layer is usually a waterproof film structure, the iso...

Embodiment Construction

[0017] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 , figure 2 The visible waterproof dressing shown is divided into a four-layer structure, which is a backing 1 , an absorption layer 2 , a wound contact layer 3 and a release layer 4 from top to bottom. The function of the backing 1 is to protect the main body of the dressing. The backing 1 is a transparent polyurethane film 12 coated with a PE or PET layer 11, wherein the polyurethane film 12 is coated with a hypoallergenic acrylate adhesive. The thickness of the PU film 12 is 0.01-0.025 mm; preferably, the thickness of the PU film 12 is 0.01, 0.015, 0.02 or 0.025 mm, more preferably 0.025 mm. When covered with a PE layer, the thickness of the PE layer is 0.01-0.05 mm, preferably 0.01, 0.02, 0.03, 0.04 or 0.05 mm, more preferably 0.05 mm. When covered with a PET layer, the thickness of the PET layer is 0.01-0.06 m...
