Description

A kind of liquid wound-protecting film and preparation method

Technical field

The present invention relates to a kind of liquid wound-protecting film and preparation method, is a kind of medical dressing, belongs to medical instruments field.

Background technology

In daily life and work, the body surface wound being caused by a variety of causes is very common, as scratch, scald etc.Traditional wound care product has ointments preparation and adhesive bandage etc., and the easy pollution clothes of ointments preparation, also easily causes the pollution again of wound, and adhesive bandage has limitation in waterproof, resistance bacterium, breathability and range of application, and affects attractive in appearance.Therefore be necessary prior art to be improved.

Liquid bandage is a kind of novel Wound dressing, and mainly by filmogen and solvent composition, and most of product has also added and has curative functional mass.Liquid in the market protects wound product and mostly contains alcohol component, can cause stronger sensation of pricking in use, affects its result of use; And the functional materials adding is mostly chemicals, there is certain security risk, be not suitable for the uses such as infant and anemia of pregnant woman.

Summary of the invention

The object of the invention is for the deficiencies in the prior art and problem, a kind of painless liquid wound-protecting film is provided, and institute's adding ingredient is natural materials, safe, there is the effect of pain relieving, antibacterial, waterproof, wound healing.

The present invention realizes by following technical proposal: a kind of liquid wound-protecting film, it is characterized in that, by mass percentage, by the nitrocotton of 5%-20%, the butyl acetate of the isoamyl acetate of 50%-80%, 10%-30%, the Oleum Caryophylli of the Oleum Ricini of 5%-10%, 0.1%-1%, the thyme oil of 0.5%-2% form.

Wherein nitrocotton is a kind of filmogen of function admirable, and water resistance is good, and intensity is higher; Isoamyl acetate and butyl acetate are the fine solvents of nitrocotton, and volatility is good and can not cause pain; Oleum Ricini is the cosolvent of nitrocotton, and can improve membranous hard, the crisp shortcoming of nitrocotton, improves pliability and the docile performance of film; Oleum Caryophylli can alleviate wound pain and promote healing; Thyme oil is a kind of natural bacteriostatic agent, and can also alleviate the sufferings sense after mosquito bite.

The preparation method of liquid wound-protecting film of the present invention is as follows:

1) isoamyl acetate, butyl acetate and Oleum Ricini are mixed in proportion;

2) nitrocotton is joined in the mixed solution of step 1) gained to stirring and dissolving;

3) Oleum Caryophylli and thyme oil are joined to step 2) in the mixed solution of gained, after mix homogeneously, obtain product.

By regulating the concentration of this product, can be prepared into spray or liniment.

The invention has the beneficial effects as follows:

1) adopt natural materials Oleum Caryophylli and thyme oil as functional material, safer to human body, there is pain relieving, antibacterial and promote the function of wound healing;

2) adopt painless formula, product is soft, can not produce sensation of pricking;

3) while using, liquid wound-protecting film is sprayed on to wound surface, 15-30 can form one deck waterproof ventilated membrane at wound surface second, and formed film is pliable and tough, and comfortableness is good.

the specific embodiment

Below principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.

Embodiment 1

Preparation method is as follows:

1) by the isoamyl acetate of recipe quantity, butyl acetate and Oleum Ricini mix homogeneously;
