Embodiment 1

[0030] see Figure 1 ~ Figure 2 , an intelligent constant temperature hot compress, which is composed of a pressure-sensitive adhesive patch 1, a heating element 2, a phase-change constant temperature layer 3, a pharmaceutical composition layer 4 and a release paper 5, and the pressure-sensitive adhesive patch 1, Heating body 2, phase change constant temperature layer 3, pharmaceutical composition layer 4 and release paper 5, the heating body 2 is bonded to the middle of the pressure-sensitive adhesive patch 1 in an island shape, and there are wing-shaped pressure-sensitive adhesive stickers on both sides or around it Cloth 1 is used to help fixation on the skin, and there is a phase-change constant temperature layer 3 on the surface of the heating element 2. The method for making the phase-change constant temperature layer 3 is to take 2g of SBS resin of model YH-801 and 10g of 300°C fraction liquid paraffin, Heat to 160°C and melt into a uniform liquid to form a soft molding...

Embodiment 2

[0032] see Figure 1 ~ Figure 2 , an intelligent constant temperature hot compress, which is composed of a pressure-sensitive adhesive patch 1, a heating element 2, a phase-change constant temperature layer 3, a pharmaceutical composition layer 4 and a release paper 5, and the pressure-sensitive adhesive patch 1, Heating body 2, phase change constant temperature layer 3, pharmaceutical composition layer 4 and release paper 5, the heating body 2 is bonded to the middle of the pressure-sensitive adhesive patch 1 in an island shape, and there are wing-shaped pressure-sensitive adhesive stickers on both sides or around it Cloth 1 is used to help fixation on the skin, and there is a phase-change constant temperature layer 3 on the surface of the heating element 2. The method for making the phase-change constant temperature layer 3 is to take 1.6g of SBS resin and 10g of liquid paraffin wax that are modeled as YH-792 and heat them to 160 ℃ melts into a uniform liquid and becomes a f...

Embodiment 3

[0034] see Figure 1 ~ Figure 2 , an intelligent constant temperature hot compress, which is composed of a pressure-sensitive adhesive patch 1, a heating element 2, a phase-change constant temperature layer 3, a pharmaceutical composition layer 4 and a release paper 5, and the pressure-sensitive adhesive patch 1, Heating body 2, phase change constant temperature layer 3, pharmaceutical composition layer 4 and release paper 5, the heating body 2 is bonded to the middle of the pressure-sensitive adhesive patch 1 in an island shape, and there are wing-shaped pressure-sensitive adhesive stickers on both sides or around it Cloth 1 is used to help fix on the skin. There is a phase change constant temperature layer 3 on the surface of the heating element 2. The preparation method of the phase change constant temperature layer 3 is to take 1g of SBS resin of model YH-802 and 10g of liquid paraffin and heat it to 160°C Melt into a uniform liquid to form a flexible molding agent; take 2...

Abstract

An intelligent constant-temperature hot-compressing patch consists of a pressure-sensitive adhesive fabric, a heating body, a phase change constant-temperature layer, a medicine composition layer and release paper, wherein the pressure-sensitive adhesive fabric, the heating body, the phase change constant-temperature layer, the medicine composition layer and the release paper are sequentially arranged from bottom to top, the heating body is located in the middle of the pressure-sensitive adhesive fabric, and the phase change constant-temperature layer is located on the surface of the heating body and is prepared from, by weight 40-60% of phase change agent, 8-25% of particle entrapment agent and 18-48% of flexible forming agent. The intelligent constant-temperature hot-compressing patch can achieve automatic constancy, enables the temperature approaching the skin temperature to be kept constant and provides higher safety guarantee by serving as a medical product attached to the skin for usage.

Description

technical field [0001] The invention relates to a medical product, which is used for thermal stimulation of meridians and acupoints, in particular to an intelligent constant temperature thermal compress. Background technique [0002] There have been many patents on the use of chemical heating agents to make medical products such as self-heating moxibustion and hot compresses. Such as CN201410734521 hot compress stick pressing pin patent, the heating agent pack and pressing pin are combined to be designed into the self-heating moxibustion patch with pressing pin. The invention can dredge the meridians and regulate qi and blood, so as to invigorate yang, promote blood circulation, eliminate cold evils, and improve therapeutic efficacy; CN201420684248 combines medicine magnetic materials and chemical self-heating body to design medicinal magnetic self-heating moxibustion, and regulates heating by sticking a film Temperature; CN201410329768 Constant-temperature self-heating mox...
