Problems solved by technology

[0002] At present, the bandage base material of medical bandages uses polyethylene or polyvinyl chloride as the backing material. Due to the lack of air permeability, the water vapor on the patient's skin surface cannot be volatilized in time, which affects wound recovery, and may cause wound infection in severe cases.
In addition, the bandaging of general adhesive bandages often leaves a little glue on the skin surface after it is untied, and when it is removed, the skin and hair will be stuck together, which increases the pain of the user.

Embodiment Construction

[0014] Such as figure 1 As shown in the air-permeable and water-repellent self-adhesive bandage, the substrate is polyurethane sponge 1, the front of polyurethane sponge 1 is compounded with elastic non-woven fabric 3 through composite adhesive layer 2, and the surface of elastic non-woven fabric 3 is coated with self-adhesive adhesive layer 4 The back of the polyurethane sponge 1 is also composited with an elastic non-woven fabric 6 through a composite adhesive layer 5, and the surface of the elastic non-woven fabric 6 is coated with a self-adhesive adhesive layer 7. Among them, the density of polyurethane sponge 1 is 28~50kg / m 3 , the thickness is 0.6 ~ 4.5mm. The elastic nonwoven fabric 3 and the elastic nonwoven fabric 6 have a thickness of 0.2-0.4 mm.

[0015] The composite adhesive layer 2 and the composite adhesive layer 5 are rubber-based adhesives or acrylic-based adhesives or polysiloxane-based adhesives or polyurethane-based adhesives. Usually, the rubber-based a...

Abstract

The invention relates to a breathable water-repellent type self-adhering bandage. In the invention, with polyurethane sponge as a substrate, the front surface of the polyurethane sponge is compounded with an elastic non-woven fabric through a composite adhesive layer, a self-adhering adhesive layer is coated on the surface of the elastic non-woven fabric, the back surface of the polyurethane sponge is also compounded with an elastic non-woven fabric through a composite adhesive layer, and a self-adhering adhesive layer is coated on the surface of the elastic non-woven fabric. The bandage has the advantages of ventilation, water-repellence, comfort and the like without piquant to skin, can be independently used and can also be used in conjunction with an ordinary self-adhering bandage.

Description

technical field [0001] The invention relates to bandages used in medical and other industries, in particular to a breathable and water-repellent self-adhesive bandage. Background technique [0002] At present, polyethylene or polyvinyl chloride is used as the backing material for the bandage base material of medical bandages. Due to the lack of air permeability, the water vapor on the patient's skin surface cannot be volatilized in time, which affects wound recovery and may cause wound infection in severe cases. In addition, the bandaging of general adhesive bandages often leaves a little glue on the skin surface after it is untied, and when it is removed, the skin and hair will be stuck together, which increases the pain of the user. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a breathable and water-repellent self-adhesive bandage. [0004] The purpose of the present invention is ach...
