Currently there are the traditional dressing of major part be by natural plant fibre or animal hair substance institute structure
At such as gauze, cotton pad, wool, all kinds of oil gauzes, this kind of dressing can not prevent outside moisture from contacting wound, easily make wound sense
Dye, therefore, proposes a kind of new medical waterproof dressing regarding to the issue above.
Summary of the invention
The purpose of the present invention is to provide a kind of new medical waterproof dressing, by the way that waterproof is arranged on the base-material of surface application
Layer, the waterproof layer include polyurethane film and the nano water-proof coating that is coated on polyurethane film, and polyurethane film passes through pressure-sensitive glue laminating
It is arranged on the base-material of surface application, polyurethane film has preferable hydrophobicity, and the nano water-proof coating being arranged on polyurethane film is
Using dimethione as the coating of raw material, dimethione is heat resistance, cold resistance, viscosity vary with temperature small, waterproof
Property, surface tension is small, has thermal conductivity, typical lyophobic dust, while having preferable waterproof performance, have preferable
Adhesiveness and thermal conductivity effectively can prevent outside moisture from entering in dressing, multiple by the way that high hydroscopic resin is arranged in dressing
Layer is closed, the moisture that dressing can be bonded to position absorbs, and avoids wound moist and the condition of the injury is caused to deteriorate, by setting inside cotton pad layer
Be equipped with styptic powder, there is clearing heat and cooling blood, the effect of activating blood and removing stasis, hemostasia and promoting granulation, can accelerating wound healing, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the invention provides the following technical scheme:
A kind of new medical waterproof dressing, including surface application and dressing, the surface application include made of melt-blown nonwoven fabric
Base-material, the base-material top are provided with waterproof layer, and the waterproof layer includes polyurethane film and pressure-sensing glue, the pressure-sensitive of the waterproof layer
Glue and base-material bond, and are provided with nano water-proof coating at the top of the polyurethane film of the waterproof layer, the base-material bottom is provided with one
Layer adhesive layer, the dressing are set to fitting and are arranged in the middle part of adhesive layer, and the dressing includes high hydroscopic resin composite layer and cotton
Bed course, the high hydroscopic resin composite layer and the fitting setting of cotton pad layer, the high hydroscopic resin composite layer and cotton pad layer are by outsourcing
Layer package.
Preferably, the nano water-proof coating of the waterproof layer with dimethione of raw material by being made.
Preferably, the adhesive layer is hydrogel.
Preferably, the cotton pad layer is internally provided with styptic powder, which is ground by the bletilla striata, cacumen biotae, rheum officinale, pseudo-ginseng
Powder is made.
Compared with prior art, the beneficial effects of the present invention are:
1, in the present invention, by the way that waterproof layer is arranged on the base-material of surface application, which includes polyurethane film and is coated in poly-
Nano water-proof coating on urethane film, polyurethane film are arranged on the base-material of surface application by pressure-sensitive glue laminating, and polyurethane film has
Preferable hydrophobicity, the nano water-proof coating being arranged on polyurethane film are using dimethione as the coating of raw material poly- two
First siloxanes is that heat resistance, cold resistance, viscosity vary with temperature that small, waterproofness, surface tension are small, have thermal conductivity, is typical
Lyophobic dust while having preferable waterproof performance, has preferable adhesiveness and thermal conductivity, can effectively prevent outside
Moisture enters in dressing.
