Problems solved by technology

Since the non-woven fabric on the outer layer of the antipyretic patch covers the hydrogel layer, the discoloration of the hydrogel layer is difficult or impossible to observe
At the same time, adding discoloration materials directly to the hydrogel layer not only increases the complexity of the process, but also causes allergies due to the delicate skin of infants and young children, and direct contact with discoloration materials

Embodiment 1

[0045] An antipyretic patch combined with an attached figure 1 And attached figure 2As shown, from the inside to the outside are the antipyretic gel layer 1, the thermochromic layer 2 and the protective layer, wherein the protective layer is a transparent film layer 3, and in order to improve the effect of heat dissipation, the surface of the film layer 3 is also provided with A number of pores 31 are beneficial for the heat generated by the human body to dissipate from the pores 31 . The temperature-sensitive color-changing layer 2 is mixed with the color-changing material indoline and polyurethane with a mass ratio of 1:3, which helps the temperature-sensitive color-changing layer 2 and the film layer 3 and the heat-relieving gel layer 1. Bonds effectively. Therefore, when the temperature of the human body exceeds 38.5 degrees, the temperature-sensing and coloring mechanism of the thermochromic layer 2 will take effect, and the preset pattern will be displayed. In additi...

Embodiment 2

[0049] A kind of preparation method of antipyretic patch, as attached image 3 shown, including the following steps:

[0050] a. Weigh 65Kg of polyvinyl alcohol and 4Kg of glutaraldehyde into the mixer, mix at a stirring speed of 100rpm, then weigh 8Kg of glycerin, 3Kg of sodium hydroxide, 5.4Kg of carbonamide, 3Kg of calcium chloride, and 4Kg of Add coral powder, 10Kg 2-acrylamide-2-methylpropanesulfonic acid, 2Kg anionic surfactant and 45Kg water into the mixer, and mix again at a stirring speed of 200rpm to obtain a mixture;

[0051] b. Put the mixture into a banburying furnace, raise the temperature to 230°C for melting and banburying, and obtain a molten body, transfer the molten body to an extruder for stretching and extrusion, obtain a film layer 3 after cooling, and use The punching machine punches out several pores 31 on the film layer 3;

[0052] c. On the film layer 3, first coat the same thermochromic layer 2 as in Example 1, and fold the edge of the film layer 3...

Abstract

The invention discloses a fever abatement patch, and relates to the field medical instruments. The fever abatement patch sequentially comprises an abatement gel layer, a temperature sensing color changing layer and a protecting layer, the protecting layer is a membrane layer, and the protecting layer is directly bonded to the abatement gel layer. The membrane layer comprises polyving akohol, glutaraldehyde, glycerol, sodium hydroxide, carbamide, calcium chloride, coral powder, 2-acrylamido-2-methylpropane sulfonic acid, anionic surfaceactive agent and water; the abatement gel layer comprises acryloyl morpholine, the 2-acrylamido-2-methylpropane sulfonic acid, sodium hydroxide, the glycerol, a bridging agent KE30, cyclohexanone peroxide and a crosslinking agent DCP. The abatement patch hasthe advantages that an observer can well observe the fever situation of a patient, a production method of the fever abatement patch is more convenient, and the fever abatement patch is suitable for massive production.

Description

technical field [0001] The invention relates to the field of medical products, in particular to an antipyretic patch and a preparation method thereof. Background technique [0002] When the human body has a cold, cold, or inflammation, many times the body will have symptoms such as fever. In the past, in order to speed up the reduction of fever, people would choose to take drugs for treatment. However, when drugs act on the human body, they often bring different degrees of side effects to the human body. Especially for infants and young children, their bodies are not yet fully developed, so once they take a large amount of antipyretic drugs for a long time, other physical lesions will often occur, which is very unfavorable for the growth and development of infants and young children. [0003] In addition, when infants have a fever and fever, infants do not feel their own body sensations like adults do self-evaluation and communication. Therefore, parents can only use frequ...
