Embodiment 1
[0035] Such as Figure 1 to Figure 2 As shown, a health-care foot patch includes a medicinal effect part and a stimulating part arranged between the adhesive layer 1 and the breathable layer 6. The stimulating part is located above the medicinal effect part, and the stimulating part is triangular in shape. Protrusions 5 are arranged on the top of the stimulation part, and the medicinal effect part protrudes inward, and the direction of the protrusion is consistent with the direction of the protrusions 5, and a plurality of massage beads 7 are evenly distributed on the medicinal effect part. The height of the protrusion is higher than the height of the bump 5, and the area of the stimulation part is 1 / 10 of that of the medicinal part. The drug effect section includes a slow-release layer 2 from inside to outside, a drug-impregnated layer 3 and an adjustment layer 4. The thickness of the sustained-release layer 2 is 10mm, the thickness of the drug-impregnated layer 3 is 8mm, a...
Embodiment 2
[0039] Three-dimensional mesh activated carbon is prepared by the following methods:
[0040] Weigh 1.5g of activated carbon, add 50mL of ammonia water with a volume fraction of 40%, seal it, stir it magnetically for 4 hours, filter it with suction, wash it with distilled water until neutral, take the filter residue, and dry it at 110°C for 24 hours to obtain modified activated carbon. spare.
[0041] Add water to swell about 10g of polyvinyl alcohol, stir slowly at 95°C until it is completely dissolved, then add soluble starch and modified activated carbon at a molar ratio of 1:1:1.5 at 70°C, mix thoroughly and add 20mL of 9% dilute Sulfuric acid solution and 40% formaldehyde solution, stir well. Place it in a constant temperature water bath at 95°C for acetalization reaction to obtain three-dimensional mesh activated carbon.
Embodiment 3
[0043] Preparation of block polyether polydimethylsiloxane:
[0044] Add M1 and monoallyl polyethylene glycol methyl ether (AEM-8) sequentially to a three-neck flask equipped with a stirrer, a thermometer and a reflux condenser, n(M1):n(AEM-8)=1.0: 1.2, pass into N 2 After stirring for 15 minutes, heat to 90~100°C, then add platinum catalyst (measured by platinum, accounting for 0.004% of the total mass of the monomer), and keep it warm for 3~5 hours, then remove low boilers at 90°C, 60kPa vacuum for 30 minutes, and cool After that, a yellowish transparent liquid was obtained, which was the target product. The viscosity (20°C) is 71mPa·s; the refractive index is 1.448. The reaction formula is:
