Problems solved by technology

But most of the water-absorbing agents used in the heat-generating agents of the existing heat-generating patches are sawdust, vermiculite, floating beads, diatomaceous earth, etc., because these materials have a low water-absorbing ratio and low water content, so more water-absorbing agents need to be housed in the heat-generating bag. The water-absorbing agent increases the weight of the heating agent, and the volume of the heating bag becomes larger. When it is pasted on the affected area, there are problems of poor fit and comfort and uneven heating, which affects the efficacy of the patch
In addition, the ventilation layer of the heating bag in the existing heating patch adopts a mechanically perforated film, which still has the problems of poor water retention, powder falling through the material, uneven ventilation, and difficult control and adjustment of the heating temperature.

Embodiment 1

[0020] Example 1: Mix 1.5 parts of polyacrylic acid-based water-absorbing resin, 1 part of salt, and 30 parts of water. After the water-absorbing resin fully expands, the water is completely absorbed into gel-state particles. The suitable particle size is 0.5-1.5 mm, and then add auxiliary 7 parts of vermiculite as a dispersant, 15 parts of activated carbon as a catalyst, and 100 parts of iron powder are mixed evenly to become a heat generating agent powder.

Embodiment 2

[0021] Embodiment 2: Get 30% (weight concentration) sodium silicate solution, spray into 5% (weight concentration) hydrochloric acid solution, form gel particle, control particle diameter 0.5~1.5mm, get 40 parts, then add auxiliary dispersion 7 parts of vermiculite agent, 15 parts of catalyst activated carbon, and 100 parts of iron powder are mixed evenly to become exothermic agent powder.

Embodiment 3

[0022] Example 3: Take 10 g of konjac flour and add 200 g of water, heat to 90-100 ° C to add 1 gram of NaOH in the form of glue, mix well and keep the temperature for 30 minutes to form an elastic gel, and grind it into particle size with a rotary knife mill Take 30 parts of 0.5-1.5mm, add 7 parts of auxiliary dispersant vermiculite, 15 parts of catalyst activated carbon, and 100 parts of iron powder and mix them evenly to become exothermic agent powder.

[0023] The air-permeable film adopted in the present invention is a microporous air-permeable film, the material is polyethylene, and the hole is formed by stretching method, the aperture is 0.1-10um, suitable for thermal bonding processing, and the air permeability is 7-20cm 3 / m 2 ·d·MP, the preferred air permeability is 15cm 3 / m 2 ·d·MP, compound it with non-woven fabric or cloth to increase strength. It can also be easily heated and bonded during packaging processing.

Abstract

The medicated heating plaster with both treating and health care functions includes a heating bag and a medicine plaster. The heating bag consists of a flat bag and heating agent comprising iron powder in 50-100 weight portions, hydrogel 5-40 weight portions, auxiliary dispersant 1-10 weight portions and catalyst 10-20 weight portions. The heating bag with hydroscopic hydrogel has light weight, small size and homogeneous heating, and possesses air permeating layer with high water keeping performance and capacity of stabilizing heating. The present invention may be adhered to the affected part for reaching local moxibustion effect. The heating temperature may be controlled through controlling the air intake amount for higher treating effect and meeting the requirement of different patients.

Description

technical field [0001] The invention relates to a fever medicine plaster with therapeutic and health care effects, which is a further improvement on the existing fever medicine plaster. Background technique [0002] In Chinese patents CN2384599 and CN2441460, a kind of fever medicine patch with the effect similar to traditional Chinese medicine moxibustion is announced. The fever medicine patch is composed of a heating bag and a plaster sheet. Blood circulation, enhance the penetration of drugs, so as to achieve better curative effect. But most of the water-absorbing agents used in the heat-generating agents of the existing heat-generating patches are sawdust, vermiculite, floating beads, diatomaceous earth, etc., because these materials have a low water-absorbing ratio and low water content, so more water-absorbing agents need to be housed in the heat-generating bag. The water-absorbing agent increases the weight of the heating agent, and the volume of the heating bag beco...
