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

A kind of heating plaster

Technical field

The present invention relates to a kind of heating plaster with treatment and health-care effect, is the further improvement to existing heating plaster.

Background technology

In Chinese patent CN2384599, CN2441460, announced a kind of heating plaster with similar traditional Chinese medical science moxibustion effect, this heating plaster is made up of heating bag and ointment table, be affixed on affected part during use, the heating that can continue, to promote partial blood circulation, strengthen the osmosis of medicine, thereby reach curative effect preferably.But the used water absorbing agent of exothermic mixture of existing heating plaster mostly adopts wood flour, Vermiculitum, floats pearl, kieselguhr etc., because the suction of these materials is than low, water content is few, more water absorbing agent need be housed in heating bag, exothermic mixture weight is increased the weight of, and the volume of heating bag becomes big, when being affixed on affected part, exist applying degree and comfortableness relatively poor, the inhomogenous problem of generating heat, thereby influence the curative effect of plaster.In addition, heating bag air-permeable layer in the existing heating plaster adopts the mechanical punching thin film, also has poor water retention property, expects dry linting thoroughly, and is ventilative irregular, the wayward and problem of regulating of heating temp.

Summary of the invention

Technical problem to be solved by this invention is the deficiency that exists at above-mentioned prior art and provide a kind of heating bag attenuation that lightens that makes under the prerequisite that does not reduce caloric value, the heating plaster of applying degree and better efficacy.

The present invention for the technical scheme that problem adopted of the above-mentioned proposition of solution is: include heating bag and ointment table, described heating bag is made of flat pocket and exothermic mixture, and its difference is that the raw material system of mixing that described exothermic mixture includes following component by weight forms:

50～100 parts of iron powders, 5～40 parts of hydrogels, 1～10 part of auxiliary dispersants, 10～20 parts of catalyst.

Press such scheme, described hydrogel is formulated by hydroscopic high-molecular resin and salt, water, and its component is by weight:

1.5 parts of hydroscopic high-molecular resins, salt 1-5 part, water 10-40 part.

Described hydrogel also can be sprayed into by 30% (weight concentration) sodium silicate solution and form gel particles in 10% (weight concentration) hydrochloric acid solution and make.

Described hydroscopic high-molecular resin is polyacrylic water-absorbing resin, gelatin, agar, Rhizoma amorphophalli, PVA resin or silicon gel; Forming particle diameter with water preparation back is the fine particle of 0.5～1.5mm.

Press such scheme, described catalyst is an active carbon; Described auxiliary dispersants is Vermiculitum, wood flour, float pearl, kieselguhr.

Press such scheme, described pocket one side is made of plastic foil 3 or pouring film non-woven fabrics, another side is made of with non-woven fabrics 1 mutually compound composite bed breathable films 2, wherein the one side of plastic foil or pouring film non-woven fabrics is the plaster face, be pasted with plaster 6, breathable films and non-woven fabric compounded layer are ventilative aspect; In the both sides of pocket or pressure sensitive film 7 can be set all around, and configuration protection release paper 8.

Press such scheme, adhere to a temperature control in the ventilative aspect of pocket and paste 5, temperature control is pasted and is simultaneously applied pressure sensitive adhesive by airtight thin film and constitute.

Beneficial effect of the present invention is: the hydrogel that 1, adopts macromolecule water uptake in exothermic mixture, because its suction is than big, water content is much higher than other water absorbing agent, therefore make heating bag weight saving, the smaller volume attenuation, be beneficial to even heating, more benefit the applying with affected part, can realize good moxibustion effect body local; 2, air-permeable layer substitutes original mechanical punching with the breathable films of micropore, good water-retaining property, not only reduced evaporation of water, can reduce the allocation ratio of water in the prescription, stop the heating powder and passed the problem that pin hole appears, and the concordance of heating temp is better, can effectively be controlled in 50～55 ℃, and heating property is more stable.The more important thing is since microporous membrane to penetrating the damping action of air, entering oxygen in the bag reacts rapidly and forms that pressure is lower than outside the bag in the bag, make two-layer bag material be close together, a bag interior powder body can not be moved freely, keep the laminar of plaster, be gathered in the pocket bottom because of action of gravity when having avoided plaster vertically to use, and then also kept the uniformity of Temperature Distribution; 3, temperature control is set and pastes,, control and regulate heating temp, more help the raising of curative effect and adapt to requirement of different patients by the control air inflow; Be in a liquid state when being the solid use when 4, preserving, can conveniently store like this, then be beneficial to the infiltration of medicine when using skin with the ointment of oil and oil soluble surfactant preparation.
