Embodiment 1

[0014] Put 95g of SIS and 5g of butyl rubber into a clean 2000mL three-necked glass bottle, add 1000-1500mL of petroleum ether with a boiling range of 60-90°C, heat in a water bath, stir to completely dissolve SIS and butyl rubber, and then add 0.5 Graft dibenzoyl peroxide for 4 hours at 60-80°C, cool to below 25°C, add 2mL peppermint oil and 1mL clove oil, and put the above glue in a 50mL special pressure-resistant aerosol can Liquid 30mL, use a special canning machine to press into 1~3g of carbon dioxide gas, and stick a label on the surface of the aerosol can to make an invisible waterproof spray on the wound.

Embodiment 2

[0016] The preparation steps are the same as in Example 1, except that the formula is changed to 95 grams of SEBS, 5 grams of butyl rubber, 1 mL of menthol, 1 gram of eugenol, 0.5 grams of oleic acid amide, 1000 to 2000 mL of petroleum ether with a boiling range of 30 to 60 °C, Use high-purity nitrogen as the aerosol propellant.

Embodiment 3

[0018] The preparation steps are the same as in Example 1, except that the formula is changed to 95 grams of SBS, 5 grams of EPDM rubber, 2 mL of litsea cubeba oil, 0.5 grams of borneol, 1000-1500 mL of n-hexane, and argon as the aerosol propellant.

Abstract

The invention discloses a wound stealth water-proof spray plaster which comprises a film forming matter, an organic solvent and an aerosol motivation agent, wherein phenylethene-isoprene-phenylethene, phenylethene-butadiene-phenylethene, phenylethene-butadiene-styrenic thermoplastic elastomer are used as film forming matter, while aerosol motivation agent employs carbon dioxide or inert gas.

Description

technical field [0001] The invention relates to an invisible waterproof spray patch for wounds. Background technique [0002] When people are engaged in labor, sports and other activities, superficial trauma often occurs accidentally. Currently the most commonly used dressing for superficial wound management is a Band-Aid. Band-aids are generally composed of three parts: gauze, rubber glue and effective medicine attached to the rubber glue. The gauze acts as a support and has the function of absorbing wound exudate. The rubber glue adheres to the skin and plays a fixed role. Drugs have antibacterial, anti-inflammatory, and hemostatic effects. Band-aids are poor in waterproofing, blocking pathogenic microorganisms, and poor in air permeability, which affects their appearance when used. In recent years, "TheJason group", "BayerAG", "Smith & Nephew medical Ltd", "TechnicalSurgical products Ltd" and other foreign manufacturers have developed organic solvent-based spray adhe...
