[0032] The invention discloses a preparation method of earthworm syrup nano-silver hydrogel patch, which comprises the following steps:
[0033] Step 1. Prepare earthworm syrup: soak earthworm in clean water to wash the soil, take it out and put it on absorbent paper to absorb the water, and obtain pretreated earthworm, mix the pretreated earthworm with sugar, and , the mass ratio of pretreated earthworm to white sugar is 1:0.6-1:1.6, and after standing for 1.5-2.5h, earthworm will gradually precipitate body fluid and shrink; the mixture is centrifuged and filtered for 2-3 times, and the leachate is taken That is earthworm syrup;
[0034] Step 2. Preparation of nano-silver: put nano-silver in distilled water, and ultrasonically treat it for 5-15 minutes to obtain nano-silver sol; wherein, the mass-volume ratio (g / L) of nano-silver to distilled water is 1:20-8:20 ;
[0035] Step 3, preparation of earthworm syrup nano-silver hydrogel patch: select sodium polyacrylate as cross-...
Embodiment 1
[0042] (1) Preparation of earthworm syrup: soak earthworm in clean water to wash the soil, take it out and put it on absorbent paper to absorb the water, weigh 10g and put it into a 50mL clean beaker, add 5g of sugar, let stand, earthworm is ready Gradually precipitate body fluid and shrink. After 2 hours, the mixture was centrifuged and filtered 2-3 times, and the leachate was obtained as earthworm syrup.
[0043] (2) Preparation of nano-silver: take nano-silver and place it in distilled water, and ultrasonically treat it for 10 minutes to obtain nano-silver sol; wherein, the mass-volume ratio (g / L) of nano-silver to distilled water is 4:20;
[0044] (3) Preparation of hydrogel patch: select sodium polyacrylate as cross-linking skeleton, aluminum glycolate as cross-linking agent, glycerin as humectant, EDTA and tartaric acid as cross-linking regulator, carbomer, CMC-Na, PVPk30 Propylene Glycol is a penetration enhancer. Weigh 9.6g glycerin and 2g ethylene glycol in a clean ...
Embodiment 2
[0046] Step 1. Prepare earthworm syrup: soak earthworm in clean water to wash the soil, take it out and put it on absorbent paper to absorb the water, and obtain pretreated earthworm, mix the pretreated earthworm with sugar, and , the mass ratio of the pretreated earthworm to white sugar is 1:0.6, and after standing for 2.5 hours, the earthworm gradually precipitates body fluid and shrinks; the mixture is centrifuged and filtered for 2-3 times, and the extract is taken as earthworm syrup;
[0047] Step 2, preparing nano-silver: take nano-silver and place it in distilled water, and ultrasonically treat it for 15 minutes to obtain nano-silver sol; wherein, the mass-volume ratio (g / L) of nano-silver to distilled water is 1:20;
[0048] Step 3, preparation of earthworm syrup nano-silver hydrogel patch: select sodium polyacrylate as cross-linking skeleton, aluminum glycolate as cross-linking agent, glycerin as humectant, EDTA and tartaric acid as cross-linking regulator, carbomer, ...
