Condition.
Further, air-permeable layer includes fibrous layer and the active carbon particle that is evenly arranged in the fibrous layer.Active carbon
Grain is adhered in fibrous layer, will not be leaked out, and active carbon has profuse hole, has powerful adsorption capacity, Ke Yi great
The earth accelerates the adsorbance and adsorption rate of wound exudate, keeps dry and comfortable in the state of being isolated from the outside wound face, improves
The venting capability of air-permeable layer.
Further, the material of fibrous layer is flax fiber layer, bamboo charcoal fiber or cotton fiber.
Further, fabric is formed by bamboo charcoal fiber and aloe fibre are blended.
Further, nanoparticle is one or more of nano zine oxide, nano-Ag particles and nanogold particle.With
Upper nanoparticle has antibacterial effect.
Further, Chinese medicine is impregnated in nanofiber.It according to circumstances can select to be impregnated with different treatment effects Chinese medicine
Dressing accelerates wound healing or accelerates therapeutic effect.
According to the above aspect of the present invention, the utility model at least has the following advantages:
By the way that waterproof layer is arranged, makes dressing that there is waterproof effect, and the tab portion of waterproof layer connection, mentioned for the replacement of dressing
Convenience has been supplied, only tab portion need to have gently been pullled, separate dressing quickly with skin, avoid traditional dressing and be bonded completely with skin
Afterwards, it is difficult to find the defect for opening the point of penetration of dressing；The setting of air-permeable layer provides ventilative function on the basis of waterproof performance
Can, improve comfort；There is antibiotic layer in dressing, greatly strengthen antibacterial effect, nanoparticle plays main anti-
Bacterium function；Medicine layer is made of nanofiber, increases specific surface area, increases the drugloading rate of dressing, honey comb like surface into
One step improves the speed of drug release, and the setting of hydrophobic layer can prevent drug from being infiltrated by wound exudate, and influence drug
Releasing effect；Adhesive layer distributes as net shape, so that dressing and skin form adhesive network face, when an external force is applied, it is easy to
Dressing is separated with skin, avoids that cambium is caused to damage.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and can be implemented in accordance with the contents of the specification, below on the preferred embodiment of the present invention and the accompanying drawings in detail

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Referring to Fig. 1-4, a kind of Medical composite dressing of the utility model, including set gradually from bottom to top waterproof layer 1,
Air-permeable layer 2, antibiotic layer 4, medicine layer 6 and adhesive layer 7.
1 edge of waterproof layer is connected with tab portion 11, and waterproof layer 1 is made of plastic film, optional aqueous polyurethane,
The one of which of polyethylene, polylactic acid or polycarbonate, waterproof layer 1 are translucent shape.Translucent waterproof layer 1 is convenient for directly sight
