preparation example Construction

[0024] The preparation method of the forsythia volatile oil medicinal hydrocolloid dressing of the present invention is specifically implemented according to the following steps:

[0025] Weigh 0.1%-10% forsythia volatile oil by mass percentage, 1%-20% water-soluble polymer material, 10%-60% rubber base material (including solvent mineral oil), 0.01%-0.2% antibacterial Oxidant, 1%-9.7% foaming agent, 0.1%-87.89% water, the sum of the contents of the above components is 100%,

[0026] First, add an appropriate amount of water to the water-soluble polymer material weighed in the previous step to make it excessively swell, then add forsythia volatile oil to form a phase I solution for later use, then add antioxidants to the rubber base material and stir evenly to form a phase II solution, and mix phase I Mix and stir the solution and phase II solution, add foaming agent and the remaining water and stir well, transfer coating on the base backing material, refrigerate at 4°C for 12...

Embodiment 1

[0030] Take by weight 5% forsythia volatile oil, 10% CMC-Na, 8% PVA, 9.99% water, 60% polyisobutylene rubber (medium hardness type), 0.01% BHT, 7% carbonic acid The mixture of sodium bicarbonate and citric acid, the molar ratio of the mixture of sodium bicarbonate and citric acid is 2:1,

[0031] Take the CMC-Na weighed in the previous step, add a small amount of water to make it swell, then add PVA, stir in a constant temperature water bath at 80°C to dissolve the CMC-Na and PVA, add forsythia volatile oil after cooling and stir evenly, as a phase I solution; Add BHT to the isobutylene rubber, heat the oil bath at high temperature and keep stirring to obtain the mixed solution of the two as the II phase solution; quickly pour the I phase solution into the II phase solution, and keep stirring to fully mix the two, and adjust the mixed solution. For the total dose, add the mixture of sodium bicarbonate and citric acid and the remaining water, stir at 80°C for 20 minutes, after ...

Embodiment 2

[0033] Take by weight 0.1% forsythia volatile oil, 1% carboxymethyl cellulose, 79% water, 5% polyisobutylene rubber (medium hardness type), 5% ethylene propylene rubber, 0.2% BHT, 9.7% mixture of sodium bicarbonate and citric acid, the molar ratio of sodium bicarbonate and citric acid is 2:1.

[0034] Take the carboxymethyl cellulose weighed in the previous step, add a small amount of water and stir to make it swell, then add the volatile oil of forsythia and stir evenly, as a phase I solution; take polyisobutylene rubber and add BHT, heat the oil bath at high temperature and continue to stir to mix, continue to stir Add phase I solution. Continue to stir until the mixture is uniform, cool, add ethylene propylene rubber, masticate at 115°C for 10 minutes, add the mixture of sodium bicarbonate and citric acid, stir at 80°C for 20 minutes, until a uniform mixture is formed, transfer coating on On the polyurethane film, refrigerate at 4°C for 12 hours, and thaw at room temperatu...

Abstract

The invention discloses a fructus forsythiae volatile oil medical hydrocolloid dressing that is formed by sticking two layers of materials, one layer of which is base mounting material, and the other layer is composed of the following components in terms of percentage by mass: 0.1%-10% of fructus forsythiae volatile oil, 1%-20% of water-soluble high polymer material, 10%-60% of rubber substrate, 0.01%-0.2% of antioxidant, 1%-9.7% of foaming agent and 0.1%-87.89% of water, wherein the total content of the above components is 100%. The method for preparing the dressing comprises the following steps of: first, adding a proper amount of water in water-soluble high polymer material so as to over-swelling the water-soluble high polymer material, then adding fructus forsythiae volatile oil to form I-phase solution, then adding antioxidant in the rubber substrate and evenly stirring to form II-phase solution, hybrid mixing I-phase solution and II-phase solution, adding foaming agent and rest water, fully stirring, transitively coating on the base mounting material, refrigerating and then unfreezing. The fructus forsythiae volatile oil medical hydrocolloid dressing has exact treatment effect, is safe and reliable, and has obviously economic benefits.

Description

technical field [0001] The invention belongs to the technical field of medical dressings, and in particular relates to a medicinal hydrocolloid dressing of forsythia volatile oil, and also relates to a preparation method of the medicinal hydrocolloid dressing. Background technique [0002] Forsythia is the fruit of Oleaceae plant Forsythin suspense (Thunb) Vahl. Dry forsythia, crush it, pass through No. 2 sieve, put it into a flask equipped with a volatile oil extractor, add 6 times the amount of water, heat and boil to extract volatile oil, carry out steam distillation, and collect the distillate until it is oil-free. The mixture was separated and dried with anhydrous sodium sulfate to obtain a volatile oil. The volatile oil has antibacterial, anti-inflammatory, antiviral and other functions. But there is no preparation of forsythia volatile oil into medicinal hydrocolloid dressing at present. Contents of the invention [0003] The purpose of the present invention is t...
