Description

Technical Field

[0001] The utility model relates to the field of wound dressings, in particular to elastic wound dressings. Background Art

[0002] Among the band-aids, the most commonly used one is benzalkonium chloride patch, which contains a cationic surfactant and has a certain bactericidal effect. It is the most commonly used surgical medicine in our lives, mainly composed of dry adhesive tape, drug-containing absorption pad and isolation permeable membrane. In a Band-Aid, the medicated absorbent pad is in direct contact with the wound, and its main function is to stop bleeding and protect the wound. After searching, the prior art (application number: CN202021488179.7) records that "when the user uses the Band-Aid, the fitting part fits the user's wound, and the adhesive part can fit the user's skin other than the wound. When the first elastic layer and the second elastic layer of the fitting part are in contact with the user's wound, the elasticity of the first elastic layer and the second elastic layer makes the fitting part fit tightly with the user's wound to prevent the Band-Aid from moving on its own. When the user's wound bleeds, the absorbent sponge in the cavity can absorb the blood produced by the user to stop bleeding from the wound." However, in the prior art, when the elastic layer of the Band-Aid is fitted, the edges become loose and warped, which can easily cause the elastic force to weaken and the Band-Aid to loosen and fall off. Utility Model Content

[0003] In order to overcome the defects of the prior art, an elastic bandage is now provided to solve the problem that the elastic layer of the bandage in the prior art becomes loose at the edge when it is attached, and the edge is easily warped, which may cause the elasticity to weaken and the bandage to loosen and fall off.

[0004] To achieve the above object, an elastic bandage is provided, comprising: a bandage body and a drug absorption pad, wherein the drug absorption pad is bonded to the middle of the inner layer of the bandage body.

[0005] The outer surface of the bandage body is fixed with an elastic external pressure belt and an auxiliary pressure belt through a reinforcement belt, and the lower surface of the drug absorption pad is bonded with an elastic internal pressure belt 1 and an elastic internal pressure belt 2 through a diaphragm. The elastic internal pressure belt 1 and the elastic internal pressure belt 2 are bonded to the diaphragm through an active adhesive layer, and cotton strips are bonded to the inner sides of the elastic internal pressure belt 1 and the elastic internal pressure belt 2.

[0006] Furthermore, the wound covering body comprises a non-woven fabric layer and an adhesive inner layer, and the lower surface of the non-woven fabric layer is bonded with the adhesive inner layer coated by heat pressing.

[0007] Furthermore, a breathable film is bonded to the outer surface of the non-woven fabric layer by heat-compression; and the reinforcing tape is bonded to the surface of the breathable film.

[0008] Furthermore, an adhesive layer is attached to the surface of the elastic external pressure belt and the auxiliary pressure belt; and a backing paper is bonded to the surface of the adhesive layer.

[0009] Furthermore, an active adhesive layer made of an active adhesive dressing material is attached to the upper surfaces of the elastic internal pressure belt 1 and the elastic internal pressure belt 2.

[0010] Furthermore, the cotton strips are distributed on the left and right sides of the drug absorption pad, and the elastic external pressure belt and the auxiliary pressure belt made of polyester, polyester and spandex blend are symmetrically attached to the surface of the bandage body.

[0011] Furthermore, the elastic external pressure belt, the auxiliary pressure belt, the elastic internal pressure belt 1 and the elastic internal pressure belt 2 constitute the elastic structure of the wound dressing body.

[0012] The beneficial effect of the utility model is that the elastic bandage of the utility model utilizes an elastic inner pressure belt and an elastic outer pressure belt to be placed inside and outside the bandage, the elastic inner pressure belt is tightly adhered to the skin outside the wound at the bonding drug absorption pad, and the elastic outer pressure belt is pulled to further cover and bond the two ends of the bandage, thereby effectively preventing the elastic bandage from loosening and falling off, enhancing the bonding firmness of the elastic bandage, and improving the compression and hemostasis effect of the elastic bandage.
