[0002]

2. Description of the Related Art Physical therapy, which is performed by giving a temperature stimulus to a living body, has been performed for a long time, and various types of heating mediums such as infrared rays, lightning baths, hot baths, and heat packs have been proposed. In recent years, a device for hyperthermia treatment has been proposed, which minimizes the intervention of a person with specialized knowledge, but it is still a treatment device and various stimulations can be applied. Since it is for giving and treating, it is necessary to comply with the usage for treating various diseases and other requirements, and it is necessary to relieve the stress caused in the lifestyle because it is complicated. It is not something that you can use freely, with peace of mind.

[0003]

In view of the above, the present invention has been found that, once a water-containing base material having water-retaining property is heated, the heat-retaining state lasts for a long time, and has reached the present invention. . That is, it is possible to give a warm feeling for a long time by preliminarily warming a water-containing base material having a high water-retaining property, and it is preferable to use a natural polysaccharide for safe use and heating. It is intended to promote the internal absorption of natural polysaccharide components into the skin. Furthermore, the present invention, by cooling the hydrogel base material at least below the body temperature, it was found that the cooling time can be maintained for a long time, which is the exact opposite of heating, but only with cooling, a pleasant feeling and a healing effect. It was possible to recover from fatigue.

The water-retaining gel base material or water-holding base material in the present invention means, for example, agar, carrageenan, furceleran, guar gum, xanthan gum, quince seed derived from quince, mucopolysaccharide such as hyaluronic acid and its salts, starch, Examples include dextran, dextrin, pullulan, cellulose and its derivatives, carboxyvinyl polymer, polyvinyl alcohol and its saponified product, polysaccharides obtained from seaweed, etc., but also saponified polyvinyl alcohol, polyvinyl formal, polyvinyl methyl ether. And copolymers thereof, vinyl-based resins such as polyvinylpyrrolidone and polyvinylmethacrylate, polyacrylic acid and sodium salts, polyacrylamide, and partial hydrolysates thereof, partially saponified polyacrylic acid ester, and poly Acrylic acid over acrylamide)
Various natural or synthetic resins having hydrophilicity such as acrylic resins such as propylene glycol, ethylene glycol,
Those obtained by softening and plasticizing with polyhydric alcohols such as glycerin are also included. What is a polysaccharide obtained from seaweed?
As mentioned above, agar (agarose, agaropectin), alginic acid and its salts, sulfated polysaccharides, etc. are exemplified. For the gel base material or water retention base material, select one of these components, or
Alternatively, a plurality of components are selected and these are combined.

The agar in the present invention is a polysaccharide extracted from red algae such as agarella and various ones can be applied, and purified agar having high gel strength is preferable. Agar is preferably contained in an amount of 2% by weight or less in order to maintain flexibility when processed into a sheet, but is not limited thereto. In the present invention, the preferable heat retention temperature is around 30 to 40 ° C., and in that range, it is preferable that the shape retention property can be maintained. On the contrary, the cooling temperature may be a temperature equal to or lower than the body temperature, and is exemplified by about 0 ° C to 30 ° C.
It is not limited to this. The heat retention time is 30 minutes or less, preferably 20 minutes or less, and therefore the size is appropriately adjusted. For example, those having a thickness of 0.1 to 10 mm are exemplified, but the thickness is not limited thereto. In some cases, a polysaccharide that can retain its shape retention up to about 50 degrees may be used.

Particularly in agar, a gel base material may be formed by its shape-retaining property, but in that case, in order to reinforce the shape-retaining property, a polyol such as glycerin is added in an amount of 0.5 to 10% by weight.
It may be formed by adding. Further, in order to enhance the shape retention property, a non-woven fabric, tulle or the like may be interposed on the surface or inside as a reinforcing material. With such a structure that the voids of the mesh-like sheet are filled, a more natural heat insulating material can be formed without adding a thickener. In addition, a heat-irreversible gelation product consisting of alginic acid or a salt thereof, water, and a calcium salt, for example, LM pectin, which is dissolved by stirring and boiling in water, and then cooled, is used.
A heat irreversible gelation product obtained by reacting with an aqueous solution of about 3% calcium chloride is also suitably used because it does not change its shape even when heated. In the present invention, sorbic acid, sodium benzoate, isobutyl P-oxybenzoate, and sodium dehydroacetate are optionally added as preservatives. Further, in the present invention, these may be used in combination in order to enhance the antiseptic effect. Alternatively, the base material may be sealed with a heat-resistant sheet and then heat-sterilized by an autoclave means (for example, 120 ° C. or lower). The quality is stable and more natural until the sheet is peeled off. A warm sensation material can be obtained.

The present invention may be of any shape as long as it can come into contact with various parts of a living body, and may have a sheet-like shape along the adaptation site or a square unit shape, which is appropriately selected depending on the use situation. To be done. Further, the present invention has a step of preheating such a gel substrate, but as a heating means therefor,
In addition to proposing a specific known heating device capable of heating to a desired temperature, it may be heated by heating in a microwave oven, warm water, or in the sun.

In addition to the case where the heating is carried out in advance, a sheet-shaped heating element with the water-containing gel base material in contact with the living body,
Infrared lamps or the like may be supplementarily combined in some cases. Further, as additives, vitamin C or its derivatives and salts, vitamins and its derivatives, various mineral components such as zinc and manganese, far infrared ray generating materials such as carbon, calcium phosphate ceramics such as chitin, chitosan and apatite, and other alumina. , Silica-based ceramics, various amino acids and peptides, proteins such as albumin, collagen, elastin, hot spring water, animal and plant oils such as herb oil, animal and plant extracts such as herb extract, yeast extract, fragrances, colorants, sugars and their derivatives , Silicone and mineral oil, essential fatty acids, urea, lactic acid, etc.
Hydroxy acid, glycyrrhizic acid salt and its derivative, essential oil such as allantrain, lemongrass and the like may be added, and in addition, if it is useful to the living body, it may be appropriately added. According to the addition, the absorption of the herb extract from the skin and the comfort of warmth due to the odor as well as the healing efficiency are improved, and relaxation of the mind and body may be achieved in a relatively short time. Further, a selective permeable membrane may be interposed at the site where the gel base material comes into contact with the skin, and by selectively applying the components of the gel base material to the skin surface, selective use by individual users, etc. Is feasible. In addition, a thickener may be added in some cases so that the gel base material is adhered and held. Further, in order to use the sensible heat of water more effectively, the sensible heat may be applied to a living body in a state of being wrapped in a resin having a high thermal conductivity so as to use only the heating effect.

Further, in the present invention, the same effect can be produced by using a sheet-like material as described above and applying a fluid, sol-like material to a living body. That is, in the present invention, a sol-like polysaccharide having a fluidity which is heated to 30 ° C to 40 ° C is formed, and this is applied to the face, hands and the like. The sol polysaccharide penetrates into wrinkles, sweat glands, etc. and adsorbs dirt. Due to the heat-retaining effect, the living body is heated for several tens of minutes and gradually cooled to gel and harden. After curing and use, this is peeled off. When peeled off, the chilled and gelled polysaccharide can be easily peeled off and does not remain on the surface of the living body. The fluidized polysaccharide heats the living body to promote blood circulation, mental healing, physical sensation, mental comfort, and separately added vitamin C and its derivatives or salts thereof, etc. It is possible to promote efficient penetration of a biologically active ingredient.

Such a flowable polysaccharide can be used more easily by using a constant temperature means for producing it. As a constant temperature means, a container containing a polysaccharide, water, etc., and 100 ° C. to 20 ° C. for the polysaccharide, water, etc.
A combination of a heater that variably heats in the range and a adjusting means such as a thermostat that adjusts an electric output for giving constant heat generation to about 40 ° C. is exemplified. That is, a polysaccharide, water, and other additives are put in a container, and an electric output is given to the heater so that the inside of the container is kept at 100 ° C to 80 ° C. After the polysaccharide is dissolved in water, the temperature is lowered to about 40 ° C. and kept constant.
In this state, a fluidized polysaccharide solution is obtained. (In the case of a gel base material, it may be produced by pouring it into a mold-like material and cooling it at a lower temperature.) At that time, even if a stirring structure such as a stirrer is added. good.

Further, the present invention has been shown in WO95 / 16431 International Publication, in which after applying the cosmetic to the living body in advance, the base material and the solized polysaccharide are applied to improve the makeup paste. By using it in combination with cosmetics, it becomes possible to make more proliferative activity of good indigenous bacteria on the skin. Further, in the base material of the present invention, WO
