Embodiment 1

[0021] Prepare an aqueous solution of ethylene glycol with a volume ratio of ethylene glycol to water of 1:5, add 10g of nano-zinc acetate to 40g of aqueous ethylene glycol, and disperse it evenly in the solution to obtain the concentration of the metal ion compound Be the ethylene glycol solution containing zinc acetate of 20wt%, activated carbon fiber adopts the viscose-based activated carbon fiber non-woven fabric, and the ethylene glycol solution containing zinc acetate is sprayed on the viscose-based activated carbon fiber non-woven fabric of 80g with a sprayer, Then dry at 50°C to prepare a viscose-based composite activated carbon fiber nonwoven fabric with a mass ratio of zinc acetate to activated carbon fiber of 1:8.

[0022] After mixing tea polyphenols and chitosan with a mass ratio of 1:10, the conventional wet spinning process is used to prepare composite chitosan fibers containing tea polyphenols, and then manufactured according to conventional non-woven fabrics T...

Embodiment 2

[0030] Referring to Example 1, the pitch-based composite activated carbon fiber non-woven fabric of 1:10 and the composite chitosan fiber non-woven fabric of 1:12 for the preparation of tea polyphenols and chitosan mass ratio are Spun and cut into shapes respectively.

[0031] The mass ratio of sulfadiazine silver to activated carbon fiber is 1:10 of pitch-based composite activated carbon fiber non-woven fabric with the chitosan fiber non-woven fabric of tea polyphenol and chitosan mass ratio of 1:12 according to the activated carbon fiber cloth. Above, the chitosan nonwoven fabric was placed in a desiccator in the order below, reacted at 80°C for 1 hour, and then taken out to obtain a self-adhesive composite activated carbon fiber dressing. And carried out performance test to this composite activated carbon fiber dressing:

Abstract

The invention discloses a self-adhesive type composite active carbon fiber dressing and a preparation method thereof. The self-adhesive type composite active carbon fiber dressing comprises a metal ion modified active carbon fiber non-woven fabric layer and a composite chitosan fiber non-woven fabric layer, wherein the composite chitosan fiber non-woven fabric layer is made from tea polyphenol and chitosan. The preparation method comprises the following steps: respectively preparing the metal ion modified active carbon fiber non-woven fabric layer and the composite chitosan fiber non-woven fabric layer made from the tea polyphenol and the chitosan; then stacking according to the sequence that the metal ion modified active carbon fiber non-woven fabric is positioned on an upper part and the composite chitosan fiber non-woven fabric made from the tea polyphenol and the chitosan is positioned on a lower part; then placing into a drier, and reacting for 1-1.5 hours at 50-80 DEG C; and taking out to obtain the self-adhesive type composite active carbon fiber dressing. The self-adhesive type composite active carbon fiber dressing disclosed by the invention not only exerts the high-efficiency solution absorption property of active carbon fibers, but also exerts the antibacterial property of the chitosan and metal ions and can be used for effectively adsorbing exudates, namely blood plasma, pustules and the like which are exudated from a wound surface without being adhered with a wound, promoting the granulation growth and accelerating the wound healing.

Description

technical field [0001] The invention belongs to the field of medical dressings, in particular to a self-adhesive composite activated carbon fiber dressing and a preparation method thereof. Background technique [0002] The medical dressing based on activated carbon fiber is a new type of dressing. Because carbon cloth has abundant micropores and high specific surface area, it can effectively absorb microorganisms and chemical substances, and has a deodorizing effect. The adsorbent itself is non-toxic, will not cause adverse changes in tissues, will not produce pigments, and will not cause granulation adhesions. According to reports, compared with other treatment methods, it can be cured in only 1 / 4 of the time. This method is suitable for large area high degree burns. For severe burns, the charcoal cloth can be rolled into a tube and used. The use of this adsorbent for patients with third-degree burns of up to 25% of the surface eliminates the need for treatment with ski...
