Embodiment 1

[0037] Implementation 1. The specific processing steps of a new type of drug-loaded band-aid with therapeutic functions are as follows:

[0038] (1) spray the mixed solution of chitosan and gentamicin sulfate on the water-absorbing pad, the concentration of chitosan in the mixed solution is 3%, the concentration of gentamicin sulfate is 0.0003%, freezes rapidly, dries;

[0039] (2) spraying the mixed solution of calcined gypsum / sheng medicine mixture and collagen, the concentration of collagen in the mixed solution is 2%, the concentration of calcined gypsum / sheng medicine mixture is 0.0002%, and freeze-drying is taken after spraying;

[0040] (3) Adhere to a layer of anti-adhesive film;

[0041] (4) After the water-absorbing pad is cut, it can be directly used in the production of band-aids.

[0042] (5) Cold seal of Band-Aid

Embodiment 2

[0043] Implementation 2. The specific processing steps of a new type of drug-loaded band-aid with therapeutic functions are as follows:

[0044] (1) spray the mixed solution of chitosan and nano-silver on the water-absorbing pad, the concentration of chitosan in the mixed solution is 3%, the concentration of nano-silver is 0.0003%, freezes and dries rapidly;

[0045] (2) spray calcined gypsum / sheng medicine mixture and chitosan mixed solution, the concentration of chitosan in the mixed solution is 3%, the concentration of calcined gypsum / sheng medicine mixture is 0.0002%, take freeze-drying after spraying;

[0046] (3) Adhere to a layer of anti-adhesive film;

[0047] (4) After the water-absorbing pad is cut, it can be directly used in the production of band-aids.

[0048] (5) Cold seal of Band-Aid

Embodiment 3

[0049] Implementation 3. The specific processing steps of a new type of drug-loaded band-aid with therapeutic functions are as follows:

[0050] (1) spray the mixed solution of chitosan and nano-silver on the water-absorbing pad, the concentration of chitosan in the mixed solution is 1%, the concentration of nano-silver is 0.0003%, freezes and dries rapidly;

[0051] (2) spraying the mixed solution of gentamicin sulfate and collagen, the concentration of collagen in the mixed solution is 2%, and the concentration of gentamicin sulfate is 0.0002%, and freeze-drying is taken after spraying;

[0052] (3) Adhere to a layer of anti-adhesive film;

[0053] (4) After the water-absorbing pad is cut, it can be directly used in the production of band-aids.

[0054] (5) Cold seal of Band-Aid

Abstract

The invention relates to a novel medicine carrying woundplast with treating functions of stopping bleeding, diminishing inflammation, sterilization and suppuration, promoting granulation and the like. The woundplast can timely treat wound and seed up wound coalescene and broadens usage of the traditional woundplast, and meanwhile the processing technology of the water uptake of the woundplast adopts a method of spraying and laminating mixed solution of multiple medicines/high polymers layer by layer, the medicines are contained in the interior of the water uptake and can realize the functions of slow releasing medicine and prolonging effective action time of medicines, which is different from the technology that medicine is directly sprayed on gauze, bandage or absorbent cotton.

Description

technical field [0001] The invention belongs to the technical field of medical equipment. The invention relates to a novel drug-loaded band-aid with therapeutic function and a preparation method thereof. technical background [0002] Band-aids are often used for hemostasis, anti-inflammation or healing of small acute wounds. They are easy to use and become necessary sanitary materials for families, hospitals and clinics. They belong to Class I medical devices. In principle, Band-Aid emphasizes water absorption, absorbs blood and wound exudate, and achieves hemostasis through physical compression. [0003] Most of the band-aids on the market now, although they can play a certain emergency protection effect on wounds, do not have the therapeutic effect of antibacterial, anti-inflammatory, and wound healing on infected wounds or slightly larger and deeper wounds. Therefore, it is of great practical significance to develop a new type of drug-loaded band-aid with therapeutic ef...
