Embodiment 1

[0035] Example 1 - Monolayer Film

[0036] Formulation: polyvinyl alcohol aqueous solution (10% by weight): 100 parts by weight

[0037] Acrylate emulsion pressure sensitive adhesive: 4 parts by weight

[0038] Glycerol: 1 part by weight

[0039] 10 g of PVA was dissolved with 90 g of deionized water under mechanical stirring at 60° C. to obtain a colorless and transparent 10 wt % polyvinyl alcohol aqueous solution. Add the acrylate emulsion pressure-sensitive adhesive and glycerol in sequence according to the formula, and stir to make the mixture evenly dispersed. Dip an appropriate amount on the glass plate with a glass rod to apply the film, or drop it on your hands. After wiping your hands evenly, dry them naturally or blow dry with warm air. The thickness of the resulting monolayer film was 0.08 mm. Can be removed or washed with cold or lukewarm water.

Embodiment 2

[0040] Example 2 - Monolayer Film

[0041] In the formula, the acrylate emulsion pressure-sensitive adhesive is 8 parts by weight, and the formula of the polyvinyl alcohol aqueous solution, glycerol and the preparation of the mixed glue are the same as those in Example 1. Choose a spray bottle with a suitable aperture to hold the glue and spray it on your hands. The thickness of the resulting monolayer film was 0.06 mm. Can be removed or washed with cold or lukewarm water.

Embodiment 3

[0042] Example 3 - Monolayer Film

[0043] Except that the concentration of the polyvinyl alcohol aqueous solution in the formula is 12% by weight, and the thickness of the monolayer film is 0.04 mm, the rest is the same as Example 1.

Abstract

A surgical liquid dressing is a monolayer film prepared by mixing glue liquid comprising the following formulated ingredients: polyvinyl alcohol aqueous solution for 100 shares by wt, acrylic ester emulsion pressure-sensitive adhesive for 4-8 shares by wt, and glycerol for 1 share by wt; another surgical liquid dressing is a bilaminar film prepared by following two layers of solution, the lower layer is polyvinyl alcohol aqueous solution, and the upper layer is polyamide alcoholic solution soluble in alcohol; and another surgical liquid dressing is a multi-laminar film prepared by following three layers of solution: the lower layer is polyvinyl alcohol aqueous solution, the middle layer is polyvinyl acetate solution soluble in alcohol, and the upper layer is polyamides alcoholic solution. A plurality of film forming materials with enough strength, water resistance and bioavailability are produced by multiple composition of one or several polymers and proper additives, and can be coated on body surface of organism, such as human hands, limbs, bellies, and etc, to acting with isolation and protection function for certain time. Said materials can be used in the medical occasion or the personal hygiene protection occasion, such as used as surgical dressing, temporary protective gloves, and etc.

Description

technical field [0001] The present invention relates to a surgical liquid dressing. It belongs to the protective dressing in the medical and hygienic fields. Background technique [0002] At present, with the increasingly severe situation of HIV, SARS, H5N1 and other viruses, people pay more and more attention to personal hygiene protection in daily life and social interaction. Medical staff who are in close contact with various viruses and bacteria need to be effectively protected. At present, the hand protection products used in my country to prevent contact with pollution sources are mainly latex or plastic film gloves. However, such products generally have shortcomings such as poor air permeability and lack of comfort, can not fully conform to each person's hand shape, greatly reduce the sensitivity of hand skin and affect hand operation function, and the disposal of disposable products needs to be recycled. . Therefore, despite the high degree of use, it still makes...
