Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a user with a safe temperature that is easy to control and does not cause low-temperature burns for a long time, is easy to handle, has a simple structure, and can be used repeatedly. It concerns a possible heating tool.

[0002]

2. Description of the Related Art Conventionally, as a heating tool, a laminate of a heating element and an adhesive layer which generate heat in the presence of air or oxygen has been studied.

In this case, as the heating element, a heating element composition, such as iron powder, activated carbon and salts, is enclosed in a sheet-like bag body made of a breathable film and having no opening. Have been proposed (Japanese Patent Laid-Open No. Sho 50).
-54188, JP-A-53-47154,
JP-A-53-60885, JP-A-54-1559
84, JP-A-55-14067 and JP-A-5.
5-166147, JP-A-62-103014, JP-B-58-22733, etc.). As is clear from those examples, this heating element can obtain a temperature of around 50 ° C.

By the way, this heating tool is used by directly contacting the outer skin, and the user can sensitively detect the temperature change, and when the temperature exceeds 44 ° C., low temperature burns occur.

Therefore, the heating element composition should be designed with due consideration to this point. If the heating element composition has a temperature of about 50 ° C., it causes low-temperature burns and cannot be directly applied to the outer skin. .

[0006] In addition, although a sheet-like bag is formed of non-woven fabric, paper or cloth, these sheets have a large pore size and, therefore, have high air permeability and moisture permeability, and therefore, the sheet is in use. As a result of not being in a depressurized state in the bag body, not only does the heating element mixture in the bag body fall during use due to its own weight and the temperature unevenly increases, but also the feeling of use deteriorates significantly.

[0007] Further, these are caused by variations in the composition of the heating element and variations in the hole diameter of the sheet bag,
There is a problem that the initial temperature tends to vary.

[0008] On the other hand, it has been proposed to fix a heating tool with a heating element to the affected area via a wearing tool such as a bandage, supporters, belts, jackets, etc. Moreover, as this heating element, the familiarity to the human body is required. To increase
A planar heating element having flexibility that can be freely bent by hand is used.

In this case, a method of supplying electric power to the sheet heating element from an external commercial power source via a control device is often used.

Recently, for example, the actual Kaihei 4-
As disclosed in Japanese Patent Laid-Open No. 103113, there is proposed a small-sized biothermal stimulation device in which a pressure-sensitive adhesive is attached to one surface so that a heating tool can be fixed to a special portion (pot).

That is, in this conventional example, an adhesive is attached to one side of a support that supports the heating element, or the heating element is covered with a cover having a significantly larger area than the heating element, and the adhesive is applied to one side of the cover. By attaching it, the heating tool can be directly adhered to the skin. However, in this case, the heating element applies heat to the skin via the heat conductor.

The heating element may be a nichrome wire, a posistor, a miniature bulb, a laser, a stroboscopic discharge tube, or a filament or a sheet-like body or a coil-like body made of a thermoelectric material such as nickel, tungsten, copper, silver or gold. Alternatively, it is a ceramic or the like that generates far infrared rays, and the heat generation temperature is designed to be about 700 ° C.

Further, in this conventional example, a method of supplying electric power to a heating element from a battery fixed to the heating element via a heat insulating material has been proposed. As a battery used in this method, a coin type or a cylinder type is used. , Rechargeable batteries such as nickel-cadmium batteries and pin-type batteries and lithium batteries are used.

[0014]

SUMMARY OF THE INVENTION In the above, the heating element of the heating tool is fixed to the affected area via the bandage, supporter, belt, jacket, or other fitting tool, and therefore cannot be directly worn by the person or It is extremely difficult for the person to wear it, and there remains a significant problem in handling.

As a method of supplying electric power to the sheet heating element, a method of supplying electric power from an external commercial power source through a control device is adopted.
There is a problem that a commercial power source is always required within the range of action of the user, and in practice, it cannot be used during work or housework activities, and its application to the affected area is significantly limited.

The above-mentioned conventional example is not applied to the hyperthermia treatment for supplying relatively low temperature heat to the skin for a relatively long time as in the present invention as in the present invention, but it is used for the hot moxibustion treatment. The heating element cyclically changes the temperature of up to about 700 ° C., and heat is applied to the pot through the heat conducting element that comes into contact with the skin.

However, this product has a remarkably high temperature, and a slight time difference may cause burns, or
On the contrary, it may not be possible to give sufficient stimulation to the skin due to the short time, and the desired effect of hot moxibustion may not be obtained. In other words, as a result of the need to control temperature and time very strictly,
Very special and expensive control equipment is required.

Further, this one is used for the treatment of moxibustion, and it changes a considerably high temperature periodically. Thus, by repeating heating and cooling of the heating element at a high temperature, Physical properties may change, burns may occur, or sufficient therapeutic effects may not be obtained.

That is, the present invention is to solve such a technical problem, and by electrically and easily controlling the temperature applied to the outer skin at 37 ° C. or higher and 43 ° C. or lower,
An object of the present invention is to provide a heating tool which can supply a user with a safe temperature without causing low-temperature burn for a long time, is easy to handle, has a simple structure, and can be repeatedly used.

[0020]

In order to achieve the above-mentioned object, a heating tool according to a first invention of the present application is provided with an adhesive material which is adhered to an outer skin, and which is laminated on one surface of the adhesive material, It is characterized by including a sheet heating element for heating the temperature of the material to 37 ° C. or more and 43 ° C. or less, and a battery for supplying electric power to the sheet heating element.

The heating tool is attached to the outer skin by an adhesive material to cover the outer skin with the adhesive material and the sheet heating element to seal the skin, and at the same time, the sheet heat is generated by the power supplied from the battery. The body is made to generate heat, and the heat of the planar heating element is applied to the outer skin via an adhesive material to obtain a heating effect.

In this case, if the temperature of the adhesive is 37 ° C. or above,
The temperature is controlled to a temperature below 3 ° C, which is a safe temperature range that does not cause low-temperature burns.
There are individual differences, and they can be controlled electrically and conveniently to adjust to their own optimum temperature range.

In order to achieve the above object, the heating tool according to the second aspect of the present invention is a heating tool having a sheet heating element, and the battery for supplying electric power to the sheet heating element is a lithium polymer battery. It is characterized by that.

In order to achieve the above-mentioned object, a heating tool according to a third invention of the present application, an adhesive material adhered to an outer skin, a sheet heating element or a resistance wire embedded in this adhesive material, and this surface It is characterized by including a battery for supplying electric power to the heating element or the resistor to heat the temperature of the adhesive material to 37 ° C. or higher and 43 ° C. or lower.

In this specification, the present invention is meant to include the first invention, the second invention and the third invention of the present application, and the outer skin is not only healthy but also includes an affected area. It means that.

Further, the heating tool is used not only to apply heat to the outer skin to overcome the cold, but also by applying heat to the affected area, for example, as a post-treatment for chronic diseases having poor drug treatment effect or surgical operation. It is applied to a part of a human body or the like where a therapeutic effect can be expected, or applied to a human body or the like where a therapeutic effect can be expected by administration of a transdermal drug.

First, the first invention of the present application (hereinafter simply referred to as the first invention) will be described in detail below.

The adhesive used in the first invention is required to be able to adhere directly to the skin of a living body and to be peeled off after use, and in order to conduct the heat of the planar heating element to the living body, it is necessary to conduct heat conduction. A material having a desired thermal conductivity can be used by appropriately selecting the heat generation temperature of the planar heating element, the film thickness of the adhesive material, and the like.

As the adhesive material, from the viewpoint of reducing the power consumption of the sheet heating element and extending the operating time,
It is preferable to select one having a high thermal conductivity and a small difference between the temperature of the sheet heating element and the skin temperature.

The adhesive material may be any material that can be peeled off after it has adhered to the skin of a living body, but it is advantageous if it can be repeatedly attached and peeled.

Further, this adhesive material may be directly adhered to the sheet heating element, or in order to facilitate repeated use, it is attached to the sheet heating element through a member having good thermal conductivity. You may.

The double-sided adhesive material used in the first aspect of the present invention is formed into a film or sheet,
The heating element is not particularly limited as long as it can be attached and held on one side thereof, and has an adhesive strength such that the other side can be attached to the outer skin and held at the application site, but is particularly attached. Those that can be repeatedly peeled off are preferable.

The adhesive material is designed so that it can be releasably attached from the sheet heating element, and its use causes foreign matter such as waste products and dust from the human body to adhere to the adhesive material. In the case where the pressure becomes low and cannot be reused, a pressure-sensitive adhesive that recovers the pressure-sensitive adhesive force after peeling the pressure-sensitive adhesive material from the sheet heating element, briefly washing with water or the like, and then drying.

As this kind of adhesive material, the above adhesive material is formed into a film or sheet (so-called gel film or gel sheet), or a material comprising a base material and an adhesive layer provided on both sides thereof. Can be mentioned,
As this base material, it is desirable that the base material has elasticity so as to follow the expansion and contraction of the application site so as to eliminate tension and discomfort and peeling, etc. It is desirable that the film or sheet is made of a transparent film or sheet.

When the pressure-sensitive adhesive is composed of a base material and a pressure-sensitive adhesive layer adhered to both surfaces thereof, the base material may be in the form of a film, a sheet or a cloth, and its material is not particularly limited. Specific examples thereof include films or sheets formed of natural or synthetic rubber or synthetic resin, or non-woven fabrics, woven fabrics, fabrics, and papers formed of synthetic resin, natural fibers, synthetic fibers or a blend thereof. To be

The synthetic resin is not particularly limited as long as it can be formed into a film or a sheet, and specifically, for example, polyethylene, polypropylene, polyamide, polyester, polyvinyl chloride, polyvinylidene chloride, Examples of the polymer material include polyurethane, polystyrene, a saponified product of ethylene-vinyl acetate copolymer, and ethylene-vinyl acetate copolymer.

Further, the base material of this adhesive material preferably has stretchability in order to enhance the conformability to the use surface,
Further, in order to enhance the heating effect (sealing effect), it is preferable that the film is not air-permeable, and from these viewpoints, a film of polyurethane, vinyl chloride or the like is preferable among the above synthetic resins.

Single-layer film-shaped or sheet-shaped polyurethane or polyurethane-based pressure-sensitive adhesive formed by pressure-sensitive adhesive
(Gel film or gel sheet), etc., having rubber-like elasticity is desirable because it gives a good feeling of use following the expansion and contraction of the use surface, and non-air-permeable ones have a thermal effect (sealing effect). It is preferable in order to increase.

By adopting such a structure as to obtain the heat effect (sealing effect), the user feels warm even if the heat supplied from the sheet heating element is controlled to a relatively low temperature. Moreover, by controlling to such a low temperature, low-temperature burns can be surely prevented, which is extremely beneficial.

The adhesive used in the present invention preferably has no skin irritation in order to prevent allergic inflammation from occurring on human skin when directly applied to the outer skin.

By the way, the pressure-sensitive adhesive used for the pressure-sensitive adhesive has a desired tackiness (tack) at room temperature and in a solventless state.
It can be attached to a sheet heating element or outer skin by simply pressing it with your finger.

The pressure-sensitive adhesive basically has a two-component skeleton of a polymer elastic body which gives cohesive force and a tackifier, and for the purpose of imparting various elasticity, a tackiness modifier, a tackiness improver and a stabilizer are added if necessary. Agents, colorants, fungicides, defoamers, thickeners, antiaging agents, etc. are added.

The polymer elastic body is a diene elastic body,
It is classified as an ethylenic elastic body or a condensed elastic body.

An adhesive using a diene-based elastic material is called a rubber-based adhesive, and includes a rubber component and a tackifier (tackifier).
Is used in a ratio of 1: 0.5 to 2.

Examples of the rubber component include natural rubber (NR), synthetic natural rubber (polyisoprene), polyurethane, styrene-butadiene rubber (SBR), butyl rubber (BR), styrene-isoprene-styrene (SIS) and styrene-butadiene-. Block copolymers such as styrene (SBS), recycled rubber, and thermoplastic rubber are mainly used.

A typical example of the ethylenic elastic body is an acrylic polymer, which is also called an acrylic adhesive. Acrylic polymer, which is the base of acrylic pressure-sensitive adhesive, generally expresses tackiness by itself, does not require a tackifier, and the monomers constituting the polymer are roughly divided into those acting as an adhesive component, those acting as an aggregating component, It consists of three components, which act as a reforming component.

The adhesive component has an alkyl group with 4 to 10 carbon atoms.
Suitable acrylic acid alkyl ester of Tg is -20 to
It is as low as -70 ° C, ethyl acrylate,
Typical examples are C ₂ or higher alkyl esters such as butyl acrylate, octyl acrylate, 2-ethylhexyl acrylate, and n-butyl acrylate.

This adhesive component is used as a main component and is rich in adhesiveness, but an aggregating component is required because it lacks cohesiveness. Examples of the aggregating component include acrylic acid esters of C _{1 to} C ₂ lower alkyl groups such as methyl acrylate, ethyl acrylate, and methyl methacrylate,
C _{2 to} C ₈ alkyl methacrylate such as alkyl methacrylate, vinyl acetate, vinyl propionate and the like C _{1 to} C ₃ vinyl ester, acrylonitrile,
Non-polymerizable monomers having a high Tg, such as vinyl monomers such as styrene and vinylidene chloride, are used. This coagulation component not only enhances cohesiveness,
It is sometimes used to improve the adhesiveness, water resistance, transparency, and other properties, and is used to bring out the special characteristics of the adhesive.

The modifying component generally includes a functional group copolymerizable with the adhesive component and the aggregating component,
Examples thereof include unsaturated carboxylic acids such as acrylic acid, methacrylic acid or maleic anhydride, unsaturated carboxylic acid amides and modified products such as acrylamide and acrylamide derivatives, hydroxyl group-containing monomers, acrylonitrile, hydroxyethyl acrylate and glycidyl acrylate. You can

This modifying component is useful not only for providing crosslinking, but also for enhancing cohesiveness and adhesiveness, and also for promoting the reaction rate during polymerization. It is also useful for

The acrylic pressure-sensitive adhesive basically contains the above-mentioned three components, but may be composed of one or two components depending on the case. In addition, the acrylic pressure-sensitive adhesive is highly transparent because it consists of a single component, and has excellent durability.
It is mainly used as an emulsion type and solution type adhesive.

As the ethylenic elastic body, a vinyl ether elastic body may be used in addition to the acrylic polymer. A pressure-sensitive adhesive using this vinyl ether-based elastic body is called a vinyl-based pressure-sensitive adhesive and is composed of a C _{2 to} C ₄ alkyl vinyl ether polymer.

In this vinyl-based pressure-sensitive adhesive, a high molecular weight substance and a low molecular weight substance are mixed to maintain the balance between the adhesive force, the holding force and the tack, but other resins are used to enhance the tack and the adhesive force. It may be used together. However, among the vinyl ether-based elastic materials, the methyl vinyl ether / maleic anhydride copolymer is water-soluble and is not suitable for the present invention.

A pressure-sensitive adhesive using the above-mentioned condensed elastic body is called a silicone-based pressure-sensitive adhesive. This silicone-based pressure-sensitive adhesive contains polydimethylsiloxane rubber as a main component, and a low molecular weight silicone resin containing dimethylsiloxane in this polydimethylsiloxane. Has been added.

The rubber-like siloxane gives the film shape and the cohesive force of the film, and the silicone resin gives the tackiness and the adhesiveness. This silicone-based pressure-sensitive adhesive can be used in a wide temperature range and has excellent heat resistance and durability.

The above tackifiers can be classified into tackifier resins, plasticizers, oils and fats, low molecular weight polymers, crosslinking agents, adhesion improvers, fillers and other compounding agents.

As the tackifying resin, rosin which is a natural resin, modified rosin, rosin or a derivative of modified rosin,
Coumarone indene resin, terpene resin (polyterpene),
Modified terpene, aliphatic hydrocarbon resin, cyclopentadiene resin, aromatic petroleum resin, non-reactive phenol resin, styrene resin, xylene resin, vinyltoluene-α-methylstyrene copolymer, etc. Things are used.

Generally, there are many solid resins, but there are liquid resins such as hydrogenated rosin and its esters. The tackifier must be one that has good compatibility with the elastic body used and imparts tackiness, and compatibility is the root of imparting tackiness. Further, it is desirable that the tackifier has no remarkable oxidizability, and from this viewpoint, hydrogenated rosin, polyterpene, C ₅ or C ₉ petroleum resin in rosin are recommended.

In order to give tackiness and tack, the kind and melting point of the tackifier are actually selected depending on the kind of the elastic body, and sometimes two or more tackifying resins are used together.

The plasticizer generally has the properties of improving processability, flexibility, elasticity and flexibility, and improving flexibility at low temperature and rubber-like elasticity, that is, cold resistance. However, since it is difficult to express the tackiness which is the essence of the tackiness agent alone, it is desirable to use it together with a tackifying resin.
Examples of plasticizers include phthalic acid-based plasticizers, phosphoric acid ester plasticizers, adipic acid ester plasticizers, sebacic acid ester plasticizers, ricinoleic acid ester plasticizers, polyester type plasticizers, and chlorinated paraffin and silicone. Can be mentioned as. High-molecular polyesters increase flexibility at low temperatures, and silicones not only improve plasticity at low temperatures but also improve low-temperature adhesion.

Oils and fats have the same function as a plasticizer, and have the purpose of imparting plasticity and the purpose of being used as a tackifier or an adhesion improver. The oils and fats include animal oils, vegetable oils, mineral oils, silicone oils and the like. These oils and fats are cheap in price and increase flexibility, which makes them attractive as a compounding agent, but caution is required in the compounding amount because they rapidly reduce the cohesiveness of the adhesive.

The high molecular weight low polymer is used for the same purpose as the plasticizer and fats and oils, and also has a role as a high molecular weight of itself. That is, it is used for tackifying property, adhesive property, flow control and the like. In the polyvinyl ether-based or polyisobutylene-based pressure-sensitive adhesives, the respective polymers have high and low molecular weights to impart tackiness, and the balance of tackiness, holding power and tack is maintained.

In addition to the above, low molecular weight polymers of high molecular weight can be found in elastic materials and tackifying resins of the pressure sensitive adhesive raw materials. SBR, BR, polyacrylic acid ester, hydrogenated rosin methyl ester in rosin-based tackifying resin,
Examples thereof include low molecular weight styrene resins and polyterpenes.

The cross-linking agent is selected depending on the elastic body to be used and what is cross-linked.
In many cases, vulcanization (crosslinking) is carried out with a vulcanization accelerator system, but an example in which an alkylphenol resin is used as a crosslinking component and aluminum alcoholate, polyisocyanate, zinc cresinate or the like is used as a crosslinking agent is particularly mentioned.

As a cross-linking agent for the rubber-based adhesive, sulfur compounds such as tetramethylthiuram disulphide, dipentamelalentiuram tetrasulfide, dibutylthiocarbamate zinc and the like, simple substances such as selenium and sulfur, oil-soluble thermosetting phenol formaldehyde Examples thereof include resins and fatty compounds such as methylolated urea formaldehyde resin.

Unlike the rubber-based pressure-sensitive adhesive, the acrylic-based pressure-sensitive adhesive has a feature that a functional group can be easily introduced into the polymer, but since the performance of the pressure-sensitive adhesive is changed depending on the crosslinking method, it is suitable for the purpose. It is necessary to select a crosslinking method.
Usually, the cross-linking method used for acrylic pressure-sensitive adhesives is carboxylic acid / polyisocyanate, N-methylol acrylamide, glycyl acrylate / amine compounds, and further various etherified aldehyde-modified carboxylic acid amides, diketone / thermosetting Are phenolic resins, epoxides or epoxy resins.

When a filler is mixed with the natural rubber or synthetic rubber used for the adhesive, the rubber is reinforced and the tensile strength, tear strength, abrasion resistance, hardness, etc. are improved,
Its volume can be increased to reduce the price.

At this time, the size, surface area, aggregated state, dispersibility, etc. of the filler particles significantly affect the reinforcing effect. It is considered that this effect adjusts the slip between the rubber and the filler by the interaction between the rubber molecule and the filler, and the presence of the filler reduces the compositional fraction of the fluid component by that much,
Since it becomes difficult to flow and lacks in tackiness, it is blended in consideration of fluidity and compression resistance at the time of use. In this case, silica gel may be used to control the compression resistance and fluidity of the filler.

The filler used for the rubber-based pressure-sensitive adhesive is roughly classified into an inorganic filler and an organic filler. Examples of the inorganic filler include metal powders such as aluminum, copper, iron and lead, siliceous materials, silicates, silica stones, diatomaceous earth, van earth soils such as alumina, calcium carbonate, limestones such as gypsum,
Examples thereof include citrus siliceous materials such as mica and clay, talc and asbestos silicic acid such as asbestos, carbon or carbides such as graphite, carbon black and white carbon, and other cement, antimony oxide, zinc white, magnesium carbonate and the like. To be

Examples of the organic filler include linters, linen, plant natural products such as sisal wood powder, animal natural products such as silk, and artificial or synthetic products such as viscose, acetate, polyamide, vinylon and vinyl chloride. As an example.

The filler does not have the effect of significantly imparting the properties relating to the adhesive, unlike other raw materials in the formulation of the adhesive, and specifically, the cohesive force is improved, the compression resistance is increased, and the flowability is increased. Has effects such as sex control. However, for example, it is necessary to pay attention to the point that the function of the pressure-sensitive adhesive may be improved to a large extent in the filler so that the adhesiveness of the polyolefin may be improved by mixing silica, and the adhesiveness may be imparted. .

The rubber-based pressure-sensitive adhesive has strong self-adhesiveness and has a characteristic that desired pressure-sensitive adhesiveness can be freely controlled by compounding, but durability is inferior to other pressure-sensitive adhesives. or,
The rubber-based pressure-sensitive adhesive is mainly used as a solution-type pressure-sensitive adhesive, and other coatings such as calendar coating and hot-melt coating are performed, but it is rarely used as an emulsion. Since the rubber-based pressure-sensitive adhesive is a multi-component type, it may be affected by the solvent used due to the difference in solubility.

Stabilizers are used especially for vinyl adhesives or vinyl resins in compounding, and are generally used for chlorine-containing resins. There are phenolic compounds, bisphenols, amines, sulfur-containing compounds, phosphites, epoxy compounds, organic metal salts, etc. to prevent polymer destruction.

The colorant is used, for example, to make the pressure-sensitive adhesive white, but when a large amount of the pigment is used, the adhesiveness is affected. In the case of white, titanium oxide having a large hiding power is often used, and zinc white, calcium carbonate and the like are also frequently used.

The anti-ultraviolet agent, like the anti-aging agent, is used for preventing yellowing due to light such as a transparent adhesive tape, and aging due to light such as blackening.
Examples thereof include benzophenone-based, salicylate-based, benzotrial-based, and substituted acrylonitrile-based materials.

Antifungal agents, defoaming agents and thickeners are particularly used for emulsion type pressure-sensitive adhesives. As antifungal agents, arsenous acid,
Examples thereof include inorganic compounds such as cuprous oxide and organic compounds such as organic sulfur compounds, phenol compounds, and organic copper compounds.

Silicone emulsions and alcohols are known as defoaming agents, but since these have a defoaming effect and peeling property (releasing property), use of an excessively large amount lowers tackiness. Let For this reason, it is necessary to select an antifoaming agent that is effective in a small amount.

The thickener is intended to increase the viscosity of the emulsion, and water-soluble polymers and colloids are generally used. It is necessary to use properly depending on the type of emulsion. For example, casein, trans rubber and the like are used for rubber latex such as SBR and NR, and PVA, sodium polyacrylate, CMC, methyl cellulose and the like are used for acrylic and vinyl emulsions. Since a thickener not only increases the viscosity but also imparts emulsion stability, it is necessary to select an appropriate thickener.
In addition, since the thickener is a high molecular substance and is contained in the pressure-sensitive adhesive layer, it is necessary to sufficiently consider that the viscosity is naturally affected.

These rubber adhesives, acrylic adhesives,
Any of the polyurethane-based adhesive and the silicone-based adhesive can be washed with water to wash away foreign matter such as dust adhering to the surface, and the adhesive will be recovered again by drying, so either may be used. In particular, it is preferable to use an acrylic pressure-sensitive adhesive which has no skin irritation and whose adhesiveness is recovered by washing and drying when the pressure-sensitive adhesive strength decreases due to repeated application and peeling. Among these, it is preferable to use a sheet obtained by molding polyacrylic acid gel into a sheet.

In the first aspect of the present invention, the adhesive material containing the sanitary agent can efficiently absorb the moisture and odorous components emitted from the living body, or the bacteria and the like generated or propagated at the application site of the heating tool and the sanitary agent. These components are useful because they can be brought into contact with each other to physically adsorb these components, chemically decompose them, or exhibit a sterilizing action or bactericidal action.

That is, when a heating tool is applied to the outer skin, heat from the sheet heating element may cause waste products such as perspiration and sweat to accumulate at the location to which the heating tool is applied, causing germs to propagate and give off an offensive odor. There is.

For this reason, it is desirable to mix a sanitary agent in the adhesive (agent) layer of the adhesive material.
For example, one or more kinds of hygiene agents such as an antibacterial agent, a bactericide, a fungicide, a deodorant and a deodorant may be mentioned.

In the present invention, the antibacterial agent, the bactericidal agent or the antifungal agent is not particularly limited as long as it exhibits a sterilizing action or a bactericidal action. Specifically, for example, a coal derivative , Salicylic acid, boric acid, coconut powder,
Iodine agents, heavy metal compounds, reverse soaps, acetic acid, fatty acid-based substances such as undecylenic acid, salicylic acid-based substances, thiantol-based substances, tar-based substances, mercury-based substances such as phenylmercuric acetate, ions, antibiotics, Examples thereof include polik, dumba, and athlete.

In the first aspect of the present invention, another example of the deodorant or deodorant may be one that oxidizes or reduces odorous components and chemically decomposes them.
The following are listed.

That is, a desiccant such as aluminum oxide, silicon oxide, magnesium oxide, titanium oxide, silica gel, zeolite, or activated carbon, or another carrier containing a decomposing agent such as a platinum group element or this compound can be mentioned. To be

In the first aspect of the present invention, the adhesive material contains or comprises a far infrared emitting substance or a magnetic substance,
This is more useful than the reason given below.

The far-infrared ray emitting substance is a substance which promotes a thermal effect by emitting far-infrared rays by a heating element or body temperature.

The far-infrared radiation material is preferably one that radiates far-infrared rays having a wavelength of about 4 to 16 μm depending on a heating element or body temperature. For example, Na ₂ O, K ₂ O, CaO, BaO,
MgO, Fe ₂ O, FeO, Fe ₂ O ₃ , SiO ₂ , Al ₂ O ₃ , Z
rO, ZrO ₂ , BeO, V ₂ O ₃ , V ₂ O ₅ , Y ₂ O ₃ , Co
O, CuO, Cu ₂ O, NiO, Ni ₂ O ₃ , MnO, MnO ₂ ,
Far infrared rays having the above wavelength may be emitted by combining inorganic oxides such as TiO, TiO ₂ , ZnO, and ThO ₂ .

Specifically, for example, 2MgO.2Al ₂ O ₃
5SiO ₂ · Fe ₂ O ₃ -based composite, Li ₂ O · Cu
O.Al ₂ O ₃ .4Si ₂ O ₂ -based composite, ZrO,
ZrO ₂ , Al ₂ O ₃ .TiO ₂ -based composite, Al ₂
Examples thereof include composites containing O ₃ · TiO ₂ as a main component.
The term "main component" as used herein means that the component may be composed only of this chemical composition or that these components may contain other components.

The magnetic substance used in the first invention exhibits a magnetic therapeutic effect by applying to the outer skin such as promotion of blood circulation.

In this case, the magnet used is 500
Gausses or more, particularly 800 gausses or more and less than 2500 gausses are desirable, but 500 gausses or less are also usable.

The shape and size of the far-infrared radiation material or magnetic material used in the first invention is not particularly limited, and the shape may be powder, hemisphere, disk shape, semielliptic shape,
Examples include a plate shape, a rectangular parallelepiped, a cube, and the like.
The size is several μm to 2000 μm, especially 10 μm to
The range of 1000 μm is preferable from the viewpoint of physical irritation to the human body.

In the first aspect of the present invention, the location of the far-infrared radiation substance or the magnetic substance to be carried on the heating tool is not particularly limited, but it is particularly contained in the adhesive material or the adhesive material and the heating element. It is desirable to carry it between the above and the above, or to carry it on the side of the surface of the adhesive material to be used for the human body, to obtain a thermal effect by far infrared rays and a magnetic therapeutic effect by magnetism.

In the present invention, an inorganic or organic water absorbing material is dispersed on the use surface side of the adhesive material, but when the heating tool is directly applied to the human body, the water absorbing material absorbs perspiration and waste products. This is advantageous because it can prevent the adhesive strength from decreasing and the skin surface at the application site can be kept clean.

In this case, when the water absorbing material has a poor affinity with the adhesive (agent) layer and there is a risk that it will not be dispersed uniformly, it is desirable to treat with a surfactant.

In the first aspect of the present invention, a transdermal drug is incorporated into the adhesive to improve the local therapeutic effect or to absorb the drug into blood or the like whose circulation is activated by the heat effect. Since the drug can be effectively circulated in each part of the body, it is preferable to increase the administration effect of each part.

It is appropriately set within the range of 01 to 30 parts by weight.

As the battery used in the first invention, either a primary battery or a secondary battery can be used as long as it is portable, and it is not particularly limited, but it is simple and economical. From the viewpoint of, a secondary battery is particularly desirable.

Specifically, for example, button-type or column-type alkaline manganese batteries or nickel-cadmium batteries,
Examples include lithium batteries, lithium polymer batteries, and solar batteries.

The power supply from the battery to the sheet heating element may be performed continuously or intermittently by repeating on / off, but the usable time of the battery is extended. In order to do so, it is desirable to do it intermittently.

That is, when the battery is used continuously and intermittently, if the capacity of the battery is constant and the ON time and the OFF time are the same, the battery can be used. This time doubles. Therefore, depending on the feeling of use of the heating tool, the on-time and the off-time may be appropriately changed to extend the use time.

In the first aspect of the present invention, the exposed surface of the sheet heating element is covered with a heat insulating material in order to reduce the power consumption of the sheet heating element and extend the operating time. It is beneficial to prevent heat dissipation from the.

The heat insulating material is not particularly limited as long as it is laminated on the exposed surface of the sheet heating element to insulate the sheet heating element.

This heat insulating material is for preventing heat from being dissipated from the planar heating element into the surrounding atmosphere, and when the battery is attached to the heating tool, the battery is exposed on the exposed surface of the heat insulating material. Is attached to prevent the heat from the sheet heating element from being transferred to the battery and the switch, which not only increases the reliability of the heating tool, but also prolongs the life of the heating tool and is extremely economical. Is.

In this case, the heat insulating material is preferably thin and has a high heat insulating effect in order to reduce the thickness of the heating tool, and is flexible in order to enhance the conformability of the heating tool to the living body surface. It needs to be there. As this heat insulating material, it is recommended to use a commercially available product in order to reduce the price.

Examples of such heat insulating materials include rubber and synthetic resin foams (for example, Calsoft (registered trademark) manufactured by Tuck System Co., Ltd., high-performance Softlon (registered trademark) manufactured by Sekisui Chemical Co., Ltd., and Toray). Examples include Torre Pef (high-pressure polyethylene) (registered trademark), flannel and the like.

By the way, in the heating tool of the first aspect of the present invention, if a battery is attached to the heating tool, portability and handling are further facilitated, which is extremely useful from this point of view.

In the first aspect of the present invention, the temperature of the pressure-sensitive adhesive that is directly adhered to the outer skin needs to be higher than the lower limit temperature at which the heating effect can be obtained, so it is necessary to control the temperature to 37 ° C. or higher. Since it is used for a long time, it is necessary to control the temperature to 43 ° C. or lower in order to prevent low temperature burns on the applied part.

This temperature control is empirically determined by, for example, obtaining a suitable resistance value and a battery voltage of the sheet heating element in which the temperature of the adhesive material is controlled to be 37 ° C. or higher and 43 ° C. or lower. It can be realized by fixedly setting the resistance value of the sheet heating element and the battery voltage to the value.

The temperature of the adhesive material is mainly determined by the skin temperature of the application part, the temperature and heat generation amount (output) of the sheet heating element, and the environmental temperature. Of these, the skin temperature and the environmental temperature of the application part are , Especially the environmental temperature changes drastically. Then, it may be difficult to fixedly set the resistance value of the sheet heating element and the battery voltage in consideration of this change.

That is, in order to surely prevent low temperature burns,
When the resistance value of the sheet heating element and the battery voltage are fixedly set and the output of the sheet heating element is set to a small value, the time until the sheet heating element reaches 37 ° C or higher at which the heating effect occurs (rise time) The problem of becoming long occurs.

Further, the resistance value of the sheet heating element decreases as the temperature rises, but since the current value increases in inverse proportion to this, it is proportional to the resistance value and proportional to the square of the current value. The output of the sheet heating element tends to increase as the temperature rises. Therefore, when the output of the sheet heating element is set to a large value in order to shorten the use time, the temperature of the sheet heating element reaches 43 ° C. or higher and the low temperature burn may occur if the use time becomes long. There are cases.

Therefore, in the first aspect of the invention, from the viewpoint of the heating effect and the prevention of low-temperature burns, the temperature detecting circuit for detecting the temperature of the adhesive material or the sheet heating element, and the temperature detected by the temperature detecting circuit are used. When the temperature of the adhesive material is less than 37 ° C, the battery voltage is controlled to increase, while when the temperature of the adhesive material exceeds 43 ° C, the output of the power source is reduced stepwise or continuously to reduce the temperature of the adhesive material. A temperature control circuit for controlling the temperature from 37 ° C to 43 ° C is provided to ensure the temperature of the adhesive material is 37 ° C.
It is useful to control the temperature above 43 ° C.

Further, in the first aspect of the present invention, as another means for achieving the object of the thermal effect and the prevention of low-temperature burn, a temperature detecting circuit for detecting the temperature of the adhesive material or the planar heating element,
A temperature control circuit for controlling the temperature of the adhesive material to 37 ° C. or higher and 43 ° C. or lower by turning on / off the power supply based on the temperature detected by the temperature detection circuit can be cited.

[0122] In addition, in this on / off control of the power source,
It also includes controlling the pulse width, frequency, or amplitude of the power output in the form of pulse.

Further, depending on the personality of the user, there is a case where the heat effect is not obtained even at about 37 ° C. because the body temperature is low, while there is a case where low temperature burn does not occur even at about 43 ° C. Considering such a case, in the first aspect of the present invention, it is preferable that the user can freely adjust or adjust the temperature of the adhesive material within the range of 37 ° C or higher and lower than 43 ° C.

That is, for example, a variable resistor connected in parallel to the sheet heating element is provided, and the current value of the sheet heating element is changed by changing the resistance value of the variable resistor to generate the amount of heat generated by the sheet heating element. Is preferably changed.

Further, in order to adjust or adjust the temperature of the adhesive material in the range of 37 ° C. or more and less than 43 ° C., a fixed resistor connected in parallel to the sheet heating element via a changeover switch is provided, This can also be realized by means of switching the current value of the sheet heating element to change the amount of heat generated by the sheet heating element by turning on / off the connection of the fixed resistor to the sheet heating element.

By the way, in the use of the heating tool, when the battery voltage during energization is constant and the resistance value is constant, the current value is constant, which facilitates the power calculation.
Therefore, in such a case, by calculating and determining the optimum resistance value in advance, a desired output can be obtained, and as a result, a special control circuit is not required, which is extremely beneficial.

Embodiments of the present invention will be specifically described below with reference to the drawings, but the present invention is not limited to these embodiments.

In the embodiment of the present invention, as shown in FIG. 1, an adhesive material 1 adhered to the outer skin, a sheet heating element 2 laminated on the adhesive material 1 in this order, a heat insulating material 3, and a battery 4 as a power source. And a switch 5 composed of a button switch, and electrically connects the battery 4, the switch 5 and the planar heating element 2 as shown in FIG.

By applying this heating tool to the outer skin with the adhesive material 1, the outer skin is covered with the adhesive material 1, the sheet heating element 2 and the heat insulating material 3 to prevent the radiation of heat radiated from the outer skin. The sheet heating element 2 is caused to generate heat by the electric power supplied from the battery 4, and this heat is applied to the outer skin to obtain a heating effect.

The adhesive material 1 is not particularly limited as long as it can be directly adhered to the outer skin of a living body and can be peeled off after use, and the heat from the sheet heating element 2 is not limited. It is for conduction to the outer skin. In this case, a material having an arbitrary thermal conductivity can be used by appropriately selecting the heat generation temperature of the sheet heating element 2 and the film thickness of the adhesive material 1.

From the viewpoint of reducing the power consumption of the sheet heating element 2 and extending the operating time, the thermal conductivity is high and the difference between the temperature of the sheet heating element 2 and the skin temperature of the outer skin is small. It is preferable to select

The adhesive material 1 may be any material that can be peeled off after adhering to the outer skin. When the adhesive material 1 can be peeled off from the sheet heating element 2, the adhesive sheet 1 is heated by sheet heating. It is preferable to peel the adhesive material 1 from the body 2, easily remove stains by washing with water, and recover the adhesive force again after drying. For example, a gel sheet including a gel sheet with cloth.

According to experiments, in order to improve the thermal efficiency of the sheet heating element 2, it is important to prevent heat radiation from the surface of the sheet heating element 2, that is, to improve the heat insulating effect. Further, it has been found that the thickness of the adhesive material 1, the type of the filler and the polymer substance, etc. are important, and by improving this heat insulating effect, an excellent heating effect can be obtained with a relatively low electric power.

Further, not only the thickness of the adhesive material 1 but also its structure is important, and specifically, the structure of the surface portion of the adhesive material 1 on the skin adhesive surface side, for example, a rough surface structure or an uneven structure is formed. Although different, it is particularly advantageous that the adhesive material 1 is provided with holes.

Next, using the sheet heating element 2 cut into a rectangle of 96 mm × 70 mm, as shown in FIG.
A heating tool including an adhesive material 1, a planar heating element 2 and a heat insulating material 3 is laminated on the above, and a temperature sensor 7 and the adhesive material 1 and the planar heating element inserted between the plate 6 and the adhesive material 1 are stacked. The temperature of the plate 6 surface and the temperature of the planar heating element 2 were measured by the temperature sensor 8 inserted between the plate 2 and the plate 2.

In this case, a 5 mm thick polycarbonate plate made by Mitsubishi Rayon is used as the plate 6, and the planar heating element 2 is made by Sakaguchi Electric Heat Co., Ltd. (SAMICON 230SR 1
0.32 Ω), the heat insulating material 3 is a stack of Sekisui Chemical's high-performance Softlon IF # 3002, and
As the adhesive material 1, a gel sheet (100F80T4-05P manufactured by Mitsui Toatsu Chemicals, Inc.) was used.

When the heating tool is applied to the outer skin (shoulder), the heating tool is manufactured by Sony Energy
TEC lithium ion battery (LiP-10)
Current at 240 mA and 37 ° C.
When the current is 570 mA, it becomes 43 ° C., and when the current is less than 240 mA, it becomes less than 37 ° C. and the heating effect becomes poor.
When the current exceeds 570 mA, it exceeds 43 ° C., which may cause low temperature burn.

By the way, this current value greatly differs depending on the heat insulating method of the surface of the sheet heating element 2, and it is extremely important to prevent heat radiation from the surface of the sheet heating element 2, and a thin and high heat insulating effect can be obtained. Preferably, it is required to be flexible in order to increase the conformability of the heating tool to the living body surface. Furthermore, in order to reduce the price, it is recommended to use a commercially available product.

As the heat insulating material 3, a foam having closed cells having a high heat insulating property and having a high expansion ratio is most preferable.

By the way, the temperature of the adhesive material 1 directly adhered to the outer skin needs to be higher than the lower limit temperature at which the heating effect can be obtained. Therefore, it is necessary to control the heat generation temperature to 37 ° C. or higher. In terms of effect, since it is used for a long time, it is necessary to control the temperature not to exceed 43 ° C in order to prevent low-temperature burns of the applied part.

In this temperature control, empirically, a suitable resistance value and a battery voltage of the sheet heating element in which the temperature of the adhesive material 1 is controlled to be 37 ° C. or higher and 43 ° C. or lower are obtained, and these suitable or optimum values are obtained. This can be achieved by fixedly setting the resistance value of the planar heating element and the output of the battery.

Next, based on the above experience, as shown in FIG. 4, from the laminated body of the gel sheet (100F80T4-05P) 1a and the heat transfer body 1b, each formed into a rectangle of 96 mm × 70 mm. Adhesive material 1, distance between electrodes 90mm, resistance value 1
A heating tool using a lithium-ion battery CR123A (3V, working voltage 2.65V) made by Fujitsu by laminating a sheet-shaped heating element 2 of 5.72Ω and a heat insulating material 3 made of high-performance softlon of grade SP # 2002 for the battery 4. I tried to find the characteristics of.

That is, this heating tool was pasted on a plate 6 made of Mitsubishi Rayon polycarbonate having a thickness of 5 mm, covered with a flannel cover 11, and the plate temperature after the switch 5 was turned on, the plate between the gel and the plate. The surface temperature, the heating element temperature (between the sheet heating element 2 and the heat insulating material 3), and the outside temperature of the heat insulating material (SP # 2002) are set to an average temperature of 20.1 ° C.
As a result of measurement in the atmosphere, the temperature change shown in FIG. 5 was observed at each measurement point.

In FIG. 4, ch.1 is a temperature sensor for detecting the plate temperature, ch.3 is a temperature sensor for detecting the outside temperature of the heat insulating material 3, and ch.4 is a temperature sensor for detecting the temperature of the sheet heating element. , Ch.5 is the plate surface (between gel and plate)
Each of the temperature sensors for detecting the temperature is shown.

As shown in FIG. 5, the plate surface temperature (between the gel and the plate) was 37 ° C. or higher 15 to 20 minutes after the start of the energization, and the maximum temperature 3 was reached 60 minutes after the start of the energization.
After recording 9.6 ° C, the temperature was gradually lowered, and the temperature exceeded 37 ° C until about 180 minutes after the start of energization. In other words, it can be seen that the heating effect is obtained from 15 to 20 minutes to 180 minutes after the start of energization.

For comparison, the same measurement was carried out using a sheet heating plate having a resistance value of 10.32 Ω. The plate surface temperature reached 47.8 ° C. and low-temperature burns were caused. Was confirmed.

Next, as shown in FIGS. 6 and 7, the gel sheet (1
00F80T4-05P) adhesive material 1 and grade IF # 300
7.7 between the heat insulating material 3 made of high-performance softlon
After sandwiching the sheet heating element 2 having a resistance value of Ω and adhering it to the left arm of a person, 3V from a power source composed of a stabilized power source,
A voltage of 0.39 A was applied to measure the environmental temperature, skin temperature, heating element temperature, and use part temperature.

6 and 7, ch.1 is a temperature sensor for measuring ambient temperature, ch.2 is a temperature sensor for measuring skin temperature, ch.3 is a temperature sensor for measuring temperature of the planar heating element 2, and ch.
4 to ch. 6 show temperature sensors for measuring the temperature of the used part (outer skin), of which ch. 4 is the temperature of the close contact part between the adhesive material 1 and the outer skin, and ch. Each temperature sensor was placed in a hole with a diameter of 5 mm, and ch.6 was placed in a hole with a diameter of 4 mm formed through the adhesive material 1, and the temperature at that site was measured. At the measurement point, the temperature change shown in FIG. 8 was observed.

From FIG. 8, when the adhesive material 1 made of the gel sheet (100F80T4-03P) is used, the temperature on the skin side of the adhesive material 1, especially the temperature sensor ch. It can be seen that the detected temperature of No. 4 exceeds 39 ° C. about 3 minutes after the start of energization.

From FIG. 9, when the adhesive material 1 made of gel sheet (100F80T4-05P) is used, the temperature detected by the temperature sensor ch.4 for measuring the temperature of the used part is 37 ° C. about 3 minutes after the start of energization.
From the above, it can be seen that the maximum temperature is 39.2 ° C.

Temperature of adhesive material 1 (temperature between adhesive material 1 and skin)
Is mainly determined by the skin temperature of the integument, the temperature and calorific value (output) of the planar heating element, and the environmental temperature. Among these, the skin temperature of the integument and the environmental temperature, especially the environmental temperature, change significantly. . Then, it may be difficult to fixedly set the resistance value and output of the planar heating element in consideration of this change.

That is, in order to surely prevent low temperature burns,
When the resistance value and the battery voltage of the sheet heating element 2 are fixedly set and the output of the sheet heating element 2 is set small, the sheet heating element 2
Does not raise the temperature to 37 ° C. or higher at which the heating effect occurs, or the time (rise time) until reaching the temperature becomes long, which causes a problem that the application time becomes long.

Further, the resistance value of the sheet heating element 2 decreases as the temperature rises, but since the current value increases in inverse proportion to this, it is proportional to the resistance value and proportional to the square of the current value. The output of the planar heating element tends to increase as the temperature rises. Therefore, when the output of the sheet heating element 2 is set large in order to reduce the use time, if the sheet heating element 2 has a long use time and the temperature of the sheet heating element 2 exceeds 43 ° C., low-temperature burn may occur. Occurs.

Therefore, in the heating tool according to another embodiment of the present invention shown in FIG. 10, in order to surely achieve the contradictory objectives of shortening the rising time and preventing low temperature burns, the above-mentioned adhesive Based on the temperature detection circuit 12 that detects the temperature of the material 1 or the planar heating element 2, the output voltage of the battery 4 is set to 37 when the temperature of the adhesive material 1 or the planar heating element 2 is based on the temperature detected by the temperature detection circuit 12. The temperature of the adhesive material 1 or the planar heating element 2 is controlled to 37 ° C or more and 43 ° C or less so that the temperature of the adhesive material 1 or the planar heating element 2 is controlled to 37 ° C by controlling the output of the battery 4 stepwise or continuously. The temperature control circuit 13 for controlling the temperature to be not lower than 43 ° C. and not higher than 43 ° C. is provided so that the temperature of the adhesive material is surely controlled to not lower than 37 ° C. and not higher than 43 ° C.

Further, in another embodiment of the present invention shown in FIG. 11, as another means for achieving the contradictory purposes of shortening the rise time and preventing low temperature burns, the above-mentioned adhesive material 1 or planar heat generation is used. Temperature detection circuit 12 for detecting the temperature of the body 2
And the temperature at which the temperature detected by the temperature detection circuit 12 is set
When the temperature rises to (45 ° C) or its vicinity, the battery 4 is turned off and 3
A temperature control circuit 14 is provided for controlling the temperature of the adhesive material 1 or the planar heating element 2 to be 37 ° C. or higher and 43 ° C. or lower by turning on the battery 4 when the temperature drops to or below 7 ° C.

In addition to this, by outputting the battery output in a pulse form and controlling the pulse width, frequency or amplitude thereof based on the output of the temperature detection circuit 12, the adhesive material 1 or the planar heating element 2 is generated. It is also possible to control the maximum temperature of 37 ° C to 43 ° C.

If the personality of the user, for example, the body temperature is low, a heating effect may be obtained even at 37 ° C. Depending on the ambient temperature used, the resistance value, the applied voltage, etc., may be based on the so-called normal temperature or room temperature. Is set and controlled.

For example, in still another embodiment of the present invention, FIG.
As shown in FIG. 2, a variable resistor 15 connected in parallel to the sheet heating element 2 is provided, and the current value of the sheet heating element 2 is changed by changing the resistance value of the variable resistor 15. It is configured to change the output of the heating element 2. The variable resistor 15 also includes a so-called semi-fixed variable resistor.

Also, in another embodiment of the present invention, FIG.
As shown in FIG. 3, the sheet heating element 2 is provided with a fixed resistor 17 connected in parallel via a changeover switch 16 such as a button switch, and the connection of the fixed resistor 17 to the sheet heating element 2 is turned on / off. Thus, the current value of the sheet heating element 2 is switched to change the output of the sheet heating element. In this case, by operating the changeover switch 16 for each of the plurality of fixed resistors 17, it is possible to obtain an output suitable for the usage environment.
