It is preferred that, the medical pressure sensitive adhesive is in acrylate pressure sensitive adhesive, polyurethane contact adhesive, medical Medical PSA
One or more.
Further, the side that the nonwoven layer is contacted with polyurethane foam is coated with medical pressure sensitive adhesive, institute
The grammes per square metre for stating non-woven cloth is 50-80 g/m2.The characteristics of described nonwoven layer has waterproof and breathable, while can prevent outer
Boundary's contaminated wound.
It is preferred that, described protective layer is made up of Ge Laxin release liners.
In use, selection is adapted to the Wound protection pad of wound size, protective layer is thrown off, the shape according to wound protects wound
The polyurethane foamed blocks in removable area are removed in the middle of protection pad, and remaining polyurethane foamed blocks not removed is contacted with intact skin, can
Strengthen the supporting role of polyurethane foam.Directly by adhered layer, by polyurethane foam and intact adhering skin, wound is smoothed
Mouth neonychium, makes adhered layer firm with skin adhesive, adhered layer plays a part of fixed Wound protection pad.
The beneficial effects of the utility model：
（1）Adhered layer dual coating of the present utility model has the medical pressure sensitive adhesive of different peel strengths, with polyurethane foam
Layer interface strength is big, and small with skin contact intensity, so, can firmly paste polyurethane foam, meanwhile, it is unlikely
Cause to pull in intact skin.
（2）Polyurethane foam of the present utility model is fixed on intact skin by adhered layer, because of polyurethane foam
With certain thickness and hardness, main support, cushioning and protection are played to wound；Have simultaneously on polyurethane foam
Micropore, gas permeability is strong.
（3）The characteristics of nonwoven layer of the present utility model not only has waterproof and breathable, and can effectively prevent the external world
Harmful substance contacts wound, further protects wound.
