Further, the regular hexagon small ventilating holes weight of the regular hexagon small ventilating holes of the silicon gel layer and air-permeable layer
It closes.Silicon gel layer is overlapped with the regular hexagon small ventilating holes of air-permeable layer, is the air-permeable layer in order to not influence air-permeable layer.
Preferably, the back sheet is highly-breathable polyurethane film.Be conducive to the evaporation of wound fluid, Neng Goufang
Only wound fluid impregnates skin for a long time, avoids skin whitening, fold.
Preferably, the back sheet inner surface is coated with medical pressure sensitive adhesive, on the one hand air-permeable layer can be fixed on to the back of the body
Above lining, on the other hand, the stickiness of back sheet can be utilized, dressing is fixed on the skin, play fixed dressing.
Preferably, the air-permeable layer is foam dressing layer.Foam dressing has good absorbency.
Preferably, the silicon gel layer is coated in by way of gluing in air-permeable layer, and the silicon gel layer is by giving birth to
Object activity glass particle and Silica hydrogel are constituted.Since silicon gel layer has good stickiness and biocompatibility, and its stickiness can
With Reusability, air-permeable layer and functional layer can be not only bonded together by silicon gel layer, and may be implemented functional layer with thoroughly
Disassembling function is realized in the separation of gas layer.
90% grain diameter is less than 40 μm in the bioactive glass particle of silicon gel layer dispersion, wherein 60% or more
The grain size of grain is less than 17 μm.Bioactivity glass has good bioactivity, and can activate has correlation gene with wound healing
Expression promotes fibroblastic proliferation and differentiation, the generation for accelerating blood vessel, promotes the growth of granulation tissue, promotes sclerous tissues
With the reparation and regeneration of soft tissue, promote the healing of wound.
Preferably, the functional layer is chitosan film.The functionality that functional layer is conducive to increase dressing is set.Chitosan
Belong to natural polymer, have good biological safety, antibiotic property, it is hemostatic, at colloidality, absorbency, with the surface of a wound
Contact, can remarkably promote the healing of the surface of a wound.
Preferably, the protective layer is off-style paper layer.
The beneficial effects of the utility model are：
（1）The utility model has antibacterial, imbibition, hemostasis, ventilative effect at the initial stage of wound healing；In wound healing
