The generation of blood vessel is grown and broken up, accelerates, promotes the growth of granulation tissue and the healing of wound.
Further, a diameter of 0.5 ~ 2 mm in the hole, the presence in hole, are conducive to increase dressing integrally-built ventilative
Property, the oxygen of abundance is provided for the surface of a wound, promotes the respiration of the surface of a wound.
Further, the bamboo fiber length is 1 ~ 5 mm, and fineness is 2 ~ 8 dtex, and bamboo fiber has good suction
Attached property, can effectively adsorb sepage and slough in the surface of a wound, salubrious healing environment is provided for the surface of a wound；Bamboo fiber is in itself
With various small gaps and cavity, with good gas permeability, with transient absorption and a large amount of sepages can be evaporated；Bamboo fiber
Possess natural antibacterial, most pathogenic bacteria can be killed, sterile healing environment is provided for the surface of a wound.
Further, a diameter of 0.1 ~ 1 mm of the acrylic resin particle；Acrylic resin has good imbibition
Property, substantial amounts of wound fluid can be absorbed, increases the absorbency and gas permeability of foam dressing.
The beneficial effects of the utility model are：（1）Using polyurethane foam and acrylic resin collective effect, make dressing
There is extremely strong absorbency, the substantial amounts of sepage of the surface of a wound can be absorbed, anti-impervious liquid side leakage impregnates normal skin；（2）Bamboo in liquid-adsorption layer
The architectural feature of fibrillation in itself and the hole for pasting layer surface setting, make dressing have good gas permeability, are on the one hand conducive to
The respiration of the surface of a wound, promotes the healing of the surface of a wound；On the other hand the sepage in dressing can be evaporated in air, reduces the surface of a wound
Load capacity, for the surface of a wound provide moistening healing environment；（3）Bamboo fiber makes dressing have antibacterial effect in liquid-adsorption layer, can be with
Kill the pathogenic bacteria contacted with the surface of a wound；（4）Silicone gel must be contained in dressing, with the good effect for suppressing scar growth；
（5）Contain bioactivity glass in dressing, fibroblastic propagation and differentiation, the generation for accelerating blood vessel can be promoted, promote
The growth of granulation tissue, promotes the healing of wound.
