Description
Technical field
The present invention relates to field of medical article technology, especially a kind of anti-infection self-degradation medical dressing of nano antibacterial.
Background technique
Wound healing is an extremely complex physiology course, and the physical fitness of patient is to determine the internal cause of wound healing,
But the effect of medical dressing is more very important.Medical dressing is a kind of critically important medical textile, with advances in technology with
And the various demands of medical field, the novel medical dressing with certain function more and more attention has been paid to.
The medical dressing now used, mostly antiseptic gauze often have the following problems when in use: 1, therapeutic agent
Overbrushing overlays on antiseptic gauze surface, and the duration is short, and slow release effect is poor, cannot persistently treat to wound；2, lack necessary
Temperature control, especially in the case of a high temperature, not can be effectively controlled wound temperature, be unfavorable for wound recovery；3, adsorption effect
Difference, essentially consists in that medical dressing hydrophily is poor, cannot effectively the absorptive tissue liquid of Fast Persistence or concentrated water etc., be easy to cause wound
Mouth festers；4, it is poor to continue bacteriostasis, is easy to cause bacteria breed, is unfavorable for wound recovery.
Summary of the invention
The present invention is in view of the above-mentioned problems, disclose a kind of anti-infection self-degradation medical dressing of nano antibacterial.
Specific technical solution is as follows:
A kind of anti-infection self-degradation medical dressing of nano antibacterial, including dressing main body and the pad pasting for being set to dressing body peripheral edge,
It is characterized in that, the dressing main body by external protection, hydrogel layer, hydrophilic antibacterial layer and natural gauze layer it is successively compound and
At the natural gauze layer is formed by stacking by least 2 layers natural gauze；
The hydrophilic antibacterial layer includes that the first gauze, disinfection cotton and the second gauze are sequentially overlapped, the disinfection cotton position
Between the first gauze and the second gauze, disinfection cotton has been embedded in hydrophilic granules and antibacterial particle；
Medicament slow release circle is attached on the lower end surface of the natural gauze layer, the medicament slow release circle is in circular ring shape, and quantity is more
It is a；
Further, the external protection is semi-permeable membrane or multilayer perforated non-woven fabric；
Further, the hydrophilic granules are sodium carboxymethylcellulose particle；
Further, the antibacterial particle is nano-Ag particles；
Further, the medicament slow release circle is formed by silk fibroin nano-fiber moulding；
It further, is in be arranged concentrically between multiple medicament slow release circles in circular ring shape；
Further, therapeutic agent is adsorbed on the medicament slow release circle.
The invention has the benefit that
The anti-infection self-degradation medical dressing of a kind of nano antibacterial disclosed by the invention, including dressing main body and pad pasting, dressing main body
It is combined by multiple functional layers, including external protection, hydrogel layer, hydrophilic antibacterial layer and natural gauze layer, external protection are
Semi-permeable membrane or multilayer perforated non-woven fabric can effectively completely cut off powder under the premise of guaranteeing ventilated using physical isolation mode
Dirt, bacterium, microorganism etc.；Hydrogel layer realizes the temperature regulation of dressing, realizes wound cooling；Hydrophilic antibacterial layer can be by hydrophilic
Granular absorption wound diffusate (tissue fluid, pus etc.), and can be continued by antibacterial particle antibacterial；Natural gauze layer sticks wound
Mouthful, medicament slow release circle thereon is formed by silk fibroin nano-fiber moulding, therapeutic agent can be injected, when medical dressing sticks wound
Mouthful when, can slow releasing pharmaceutical, continuingly act on wound, reach therapeutic purposes.
