Every summer is the hottest time for hydrogel machines. The hot sales of cold applicators, antipyretic applicators and other products have laid the foundation for equipment sales. What kind of treatment does the hydrogel cold applicator use? How should it be handled?

　　The hydrogel cold patch is based on the principle of transdermal absorption, and the related drugs are made into nano-techniques to be microparticles, and a new type of skin-imparting agent made of water-soluble polymer gel is used for topical application to avoid the first-pass effect of drugs. , Improve the bioavailability of drugs, side effects are small.

　　Hydrogel cold-applied polymer water-soluble gel paste (water content more than 30%), has a strong water retention, can moisturize the skin, promote drug and skin contact, is conducive to the absorption of active ingredients. The hydrogel cold patch was applied to the skin for 15 minutes, and the drug began to penetrate deep into the skin. After 3 hours, the plasma concentration peaked and the efficacy lasted for more than 12 hours. The base cloth made of stretchable non-woven fabric has good air permeability, no irritation to the skin, no irritation and irritation, and the hydrogel cold paste sticks on the joints can still move freely, and feels good after being attached.

　　After muscle strain or joint sprain after strenuous exercise, do not immediately heat or plaster, because many plasters are irritating, or have a heating effect, heat and plaster can cause capillary expansion, increase capillary bleeding and muscle swelling , making the injury worse

　　In the event of strain or sprain, exercise should be stopped immediately. If cramps occur, the muscles in the cramps should be stretched in the reverse direction and a local massage should be performed. If there is a muscle strain, apply a hydrogel cold patch immediately to the sore area for 30 minutes. Avoid rubbing and hot compress. After 24 hours, massage properly. Control of the spread of inflammation, cold blood vessels can be used to shrink, local blood flow slows, reducing the vitality and metabolism of cells, but also reduces the vitality of bacteria, so it is often used in early inflammation. By lowering body temperature, when it is directly in contact with the skin by cold, physical conduction can radiate heat conduction in the body and reduce the body temperature, so it is often used in patients with high fever and heat stroke.
