Example Embodiment

[0008] The present invention will be further described now in conjunction with accompanying drawing. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention, and should not be construed as limiting the implementation of the present invention.

[0009] like figure 1 In the dressing shown, there is an adhesive layer 2 on the base cloth 1, and a protective layer 3 is pasted on the adhesive layer 2 in the middle of the base cloth 1. The protective layer is impregnated or coated with medicines for promoting wound healing or sprain recovery. Covered with a release paper 4, the outer edge of the release paper 4 is fixed on the corresponding exposed part around the base cloth 1.

[0010] The medical thermoplastic polyurethane film is processed into a mesh structure with an opening rate of 75%, and then hot-pressed and fixed on the base fab...

Abstract

A dressing with a mesh reinforcing layer is provided with elastic webbing serving as base cloth 1, the inner face of the base cloth is coated with a mucilage glue layer 2, a protection layer 3 is stuck on the mucilage glue layer in the middle of the base cloth and is soaked or coated with medicine for promoting a wound to heal or a sprain to recover, the protection layer is covered with separating paper 4, and the edge of the separating paper is fixed to the corresponding exposed part of the periphery of the base cloth. The dressing with the mesh reinforcing layer is characterized in that a medical mesh TPU film fixed on the outer side of the base cloth in a hot pressing mode serves as the mesh reinforcing layer (5), the aperture ratio of the mesh reinforcing layer is 60-80%, and the thickness of the mesh reinforcing layer is 0.2-0.4 mm.

Description

field of invention [0001] The invention relates to a medical dressing. Background technique [0002] The medical thermoplastic polyurethane resin (TPU) film has a high modulus of elasticity and can fix the wound well. However, because it is completely airtight and the sense of restraint is too strong, the compliance of using TPU film material is not good. [0003] Medical dressings generally include an adhesive layer, a base cloth and a protective layer, which are attached to the surface of the wound through the protective layer to prevent further infection of the wound. However, in order to ensure that the surface is breathable and movable, the general dressing base layer often adopts materials with high air permeability, low elastic modulus, and high elongation, but this material has poor fixation performance. When it is fixed to a certain degree, it cannot meet the needs, Invention content: [0004] The invention provides a dressing with a net-like reinforcing layer, ...
