Problems solved by technology
[0002] At present, when many hospitals are dealing with moderate skin trauma caused by burns and knife wounds, when bandaging with cotton gauze, it is very easy to coagulate and adhere to the wound, resulting in difficulty in disassembly, re-injury of the wound, and pain for the injured.
In addition, cotton gauze dressing has poor heat dissipation, high disinfection requirements, inconvenient storage, easy to invade by germs, absorbs blood and hardens, and has no astringent and healing effects on wounds
In the existing technology, the non-stick wound gauze developed by Dali Medical College is processed from wood fiber, etc. It is characterized in that it can still maintain a certain degree of softness after absorbing blood and exudate, but this material is still mixed with blood and water on the wound surface. At the same time, if the material is sterilized or stored improperly, bacteria can easily enter the blood circulation system through the wound and cause serious blood diseases
Band-aids are only suitable for minor skin injuries such as small cuts and abrasions. Although the moderate wound materials produced by 3M have a non-stick effect, they have poor heat dissipation and some are easy to fall off

Embodiment Construction
[0008] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.
[0009] like figure 1 As shown, the present invention includes a plaster layer 2, a breathable non-stick layer 3, an absorbing layer 4, and a breathable elastic belt layer 5.
[0010] The bandaging health plaster has four layers, the first layer closest to the wound surface 1 is a plaster layer 2, the second layer is a breathable non-stick layer 3, the third layer is an absorbing layer 4, and the fourth layer is a breathable elastic belt layer 5. The air-permeable non-stick layer 3, the absorbing layer 4, and the air-permeable elastic belt layer 5 are superimposed on each other in parallel. The edges of these three layers of materials are thermally bonded, and pressure-sensitive tapes can be added to the edges of both ends according to the needs of the wound. The plaster layer 2 adopts the special-effect plaster through drug testing to be...

An adhesive bandage for the medium-depth skin wound is composed of a plaster layer, an air-permeable non-adhesive layer made of a plaster layer, an air-permeable non-adhesive layer made of non-woven cloth, an absorption layer consisting of two surficial medical non-woven cloth layers and a sandwich layer of loose wool, and an air-permeable elastic layer made of porous elastic fibre cloth.
Description
Technical field: [0001] The invention relates to a skin wound wrapping health patch, in particular a non-adhesive wound, good air permeability, which is helpful for the natural recovery of the wound, and a convenient medium-depth skin wound wrapping health patch, which belongs to the medical and health material technology field. Background technique [0002] At present, when many hospitals are dealing with moderate skin trauma caused by burns and knife wounds, when they use cotton gauze for dressing, it is very easy to coagulate and adhere to the wound, resulting in difficulty in disassembly, re-injury of the wound, and pain for the injured. Moreover, the cotton gauze dressing has poor heat dissipation, high disinfection requirements, inconvenient storage, easy invasion by germs, absorbs blood and hardens, and has no astringent and healing-promoting effects on wounds. In the existing technology, the non-stick wound gauze developed by Dali Medical College is processed from w...
