CN102166369A - Liquid woundplast and preparation technology thereof - Google Patents

Abstract

The invention discloses a liquid woundplast and a preparation technology thereof. The liquid woundplast comprises the raw materials based on weight percentage: 1%-5% of poval, 1%-5% of gum rosin, 1%-5% of beewax, 10-30% of gum turpentine, 60-90% of 75% alcohol and 1%-8% of purified water. The preparation technology of the liquid woundplast comprises the steps of: adding the poval into the heated and cooled purified water, abundantly stirring and evenly dispersing, adding the mixture of the gum rosin, the beewax, the gum turpentine and the alcohol, and dissolving in a stirring way to obtain the liquid woundplast. The liquid woundplast is taken as a spray agent to be directly sprayed to the wound when the liquid woundplast is in use, a layer of transparent film can be fast formed on the wound, and the transparent film has a waterproof function, can not fallen off for 72h, and can prevent the wound from being invaded by the external bacterium, so that the wound can be fast healed, and the problems that the conventional woundplast is unattractive in appearance and the wound is unfree to move are solved.

Description

Liquid adhesive bandage and preparation technology thereof

Technical field

The present invention relates to medical instruments field, be specifically related to liquid adhesive bandage and preparation technology thereof.

Background technology

Common adhesive bandage on the existing market, a kind of is medical proof fabric+non-woven fabrics, and another kind is PU film+non-woven fabrics, is attached on the little wound surface, and one influences the free movable of wound site, also influences very much attractive in appearance in addition.

Summary of the invention

The object of the present invention is to provide a kind of liquid adhesive bandage and preparation technology thereof of spray agent formula, solved attractive in appearance, the movable comfortless defective of wound of influence of traditional bandage.

The liquid adhesive bandage, by mass percentage, the polyvinyl alcohol by 1%～5%, 1%～5% gum rosin, 1%～5% Cera Flava, 10%～30% gum turpentine, 60%～90% ethanol 75% and 1%～8% purified water are formed.

A kind of technology for preparing described liquid adhesive bandage, concrete steps are:

1) premixing: gum rosin, Cera Flava, gum turpentine are added in the ethanol, standby behind the mix homogeneously;

2) purified water is heated to 90 ℃, is incubated after 25 minutes, be cooled to 40 ℃;

3) polyvinyl alcohol being added through step 2) in the purified water after handling, fully dispersed with stirring is even;

4) the premixing material is added in the mixed liquor that step 3) is handled, after the stirring and dissolving, promptly get the liquid adhesive bandage.

Beneficial effect: liquid adhesive bandage of the present invention is a spray agent, directly aim at the wound surface spraying during use, form the film of layer of transparent fast at wound surface, film also has waterproof effect simultaneously, can keep not coming off in 72 hours, intercept the intrusion of extraneous antibacterial, made wound surface accelerate healing, solved attractive in appearance, the movable comfortless defective of wound of influence of traditional bandage.

The specific embodiment

Embodiment 1

Liquid adhesive bandage of the present invention, by mass percentage, the polyvinyl alcohol by 2%, 2% gum rosin, 2% Cera Flava, 15% gum turpentine, 75% ethanol and 4% purified water are formed.

A kind of technology for preparing described liquid adhesive bandage, concrete steps are:

1) premixing: 8g gum rosin, 8g Cera Flava, 8g gum turpentine are added in the 300g ethanol mix homogeneously;

2) the 16g purified water is heated to 90 ℃, is incubated after 25 minutes, be cooled to 40 ℃;

3) with in the purified water after the 8g polyvinyl alcohol adding cooling, fully dispersed with stirring is even;

4) the premixing material is added in the mixed liquor that step 3) is handled, after the stirring and dissolving, promptly get the liquid adhesive bandage.

Liquid adhesive bandage of the present invention is a spray agent, directly aims at the wound surface spraying during use, forms the film of layer of transparent fast at wound surface, and film also has waterproof effect simultaneously, can keep not coming off in 72 hours, has intercepted the intrusion of extraneous antibacterial, makes wound surface accelerate healing.
