The cooling gel patch is made according to the traditional cold-pressing method, and the new drug release system of TDDS prepared on the basis of polymer gel is composed of the backing layer, the gel layer and the anti-sticking layer. Cold paste can make local capillary contraction, can reduce the sensitivity of nerve endings to reduce the pain, cooling fever, can reduce local blood flow, prevent inflammation and suppurative spread.Can be the body's heat conduction divergence, increase heat, reduce body temperature. Medical fever paste for physical fever, cold treatment, closed soft foot tissue. Generally by the million weaving, menthol, p-hydroxybenzoic acid, water, high molecular substances (including glycerol) and other components.
With the help of water, ethanol evaporative heat, so that heat can be physical cooling. Studies suggest that the heat paste by the polymer hydrogel with mint and other natural ingredients made of mint flavor, cool, with volatile oil, the skin has a stimulating effect, can stimulate the nerve endings cold sensation, resulting in cold feeling.
Although the heat of the gelatinous material in the water vaporization can take away the heat, but there will not be excessive cooling, which has important ingredients, through subcutaneous penetration, reduce brain blood volume, reduce brain edema, there Ning Shen Xingnao role, can reduce the fever caused by dizziness, headache, the role of cooling in more than 6 hours.
However, experts also pointed out that the cooling gel patch on the forehead to reduce the effect of limited temperature, because the forehead capillaries less. Cooling effect is better posted on the armpit or groin, but posted here children will feel uncomfortable.
Antipyretic can not be reused, cooling gel patch can be repeated smear, when used to tear the bag along the gap, remove the patch, opened a transparent film, the gel surface directly applied to the forehead or temple, Affixed to the neck Dazhui; in order to speed up the cooling rate can be added with the number of stickers attached to the human body around the common carotid artery, left and right femoral artery. 1-3 times a day, each paste can be applied for more than 8 hours.
