Definitions
- the invention belongs to the technical field of medical devices, and particularly relates to a liquid band-aid and a preparation method thereof.
- liquid Band-Aids mostly use a single permeability modifier, which has insufficient air permeability, and when the water-soluble polymer is used as the film-forming material, although it has excellent water absorption and swelling properties, the film is brittle and has poor adhesion.
- the liquid Band-Aid cannot have the characteristics of better film flexibility, good adhesion, good water absorption and swelling, and good air permeability.
- the main purpose of the present invention is to provide a liquid Band-Aid, using ethyl cellulose, carboxymethyl chitosan, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, Polyvinylpyrrolidone-vinyl acetate copolymer is used as a joint film-forming agent, and hydrogen peroxide is used as a gas permeability modifier, so that the liquid Band-Aid has the characteristics of film flexibility, adhesion, water absorption and swelling, and air permeability.
- the present invention provides the following technical solutions:
- a liquid Band-Aid comprising the following components by weight:
- the plasticizer is diethyl phthalate.
- the preparation method of the liquid Band-Aid comprises the following steps:
- the present invention adopts ethyl cellulose, carboxymethyl chitosan, water-soluble hydroxyethyl cellulose, hydroxypropyl methyl cellulose, polyvinyl pyrrolidone-vinyl acetate copolymer as a film-forming material, and the ethyl cellulose dissolves After ethanol and ethyl acetate, a uniform ethyl cellulose film is formed.
- the ethyl cellulose film is a porous polymer film with many small nano-scale pores, water-soluble carboxymethyl chitosan, hydroxyethyl cellulose Ethyl cellulose, hydroxypropyl methyl cellulose, polyvinyl pyrrolidone-vinyl acetate copolymer are embedded in the nano-scale holes of ethyl cellulose film to form good flexibility and elasticity, strong adhesion, water absorption and swelling and breathability Good composite film.
- the ethyl cellulose film has good flexibility and elasticity, and can prevent the contamination of the wound by external bacteria;
- Carboxymethyl chitosan exerts anti-inflammatory and hemostatic effects to promote rapid wound healing
- Water-soluble hydroxyethyl cellulose is used to improve the adhesiveness of the composite film and the adhesive ability of the liquid Band-Aid;
- Hydroxypropyl methylcellulose and polyvinylpyrrolidone-vinyl acetate copolymer are used to form through holes in the composite film and play an excellent role in air permeability. They are good air permeability improvers; hydrogen peroxide releases oxygen by releasing its own disproportionation reaction to achieve The air permeability improver further improves the air permeability of the composite film of the liquid Band-Aid through the synergistic effect of hydroxypropyl methylcellulose, polyvinylpyrrolidone-vinyl acetate copolymer and hydrogen peroxide.
- the hydrogen peroxide has the effect of bactericidal and anti-inflammatory, and the synergistic effect of the hydrogen peroxide and the carboxymethyl chitosan improves the anti-inflammatory and bactericidal functions of the liquid band-aid.
- a liquid Band-Aid comprising the following components by weight:

Description
本发明属于医疗器械技术领域,具体涉及一种液体创可贴及其制备方法。The invention belongs to the technical field of medical devices, and particularly relates to a liquid band-aid and a preparation method thereof.
生活中小面积创伤通常以创可贴包扎,尽管可以保护创面,但是也存在一定弊端,比如关节处等特殊部位的创面的包扎容易变形脱落,且需要反复多次更换易造成伤口的二次伤害,同时包裹后透气性差,创口分泌的水汽和汗液不能及时渗出,会对局部皮肤产生浸泡作用,易导致细菌的继发感染,且纱布或者创可贴包扎无法完全隔绝伤口与外界的接触,易导致灰尘或者水渗入伤口,不利于伤口恢复。因此,液体创可贴的研究应运而生,目前对其研究也在不断深入。但是发明人发现现有创可贴具有以下缺陷:Small-area wounds in life are usually bandaged with band-aids. Although it can protect the wound surface, it also has certain drawbacks. For example, the bandaging of the wound surface in special parts such as joints is easy to deform and fall off, and it needs to be replaced repeatedly, which may cause secondary damage to the wound. The air permeability is poor, and the water vapor and sweat secreted by the wound cannot seep out in time, which will soak the local skin and easily lead to secondary infection of bacteria, and gauze or band-aid dressing cannot completely isolate the wound from contact with the outside world, which may easily lead to dust or water. It penetrates into the wound and is not conducive to wound recovery. Therefore, the research of liquid Band-Aid came into being, and the research on it is also deepening. However, the inventor found that the existing Band-Aid has the following defects:
目前液体创可贴多采用单一的通透改良剂,其透气性不够好,且单纯以水溶性高分子聚合物为成膜材料时虽然有优良的吸水溶涨性,但是膜脆、粘接力差,目前液体创可贴不能兼具较佳的膜柔韧性与粘接力好、吸水溶涨性好、透气性好的特性。At present, liquid Band-Aids mostly use a single permeability modifier, which has insufficient air permeability, and when the water-soluble polymer is used as the film-forming material, although it has excellent water absorption and swelling properties, the film is brittle and has poor adhesion. At present, the liquid Band-Aid cannot have the characteristics of better film flexibility, good adhesion, good water absorption and swelling, and good air permeability.
鉴于现有技术中存在的不足之处,有必要提供一种液体创可贴及其制备方法。In view of the deficiencies in the prior art, it is necessary to provide a liquid Band-Aid and a preparation method thereof.
