Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a massage pack suitable for treatment of painful diseases such as rheumatoid arthritis, treatment of muscle stiffness due to exercise, and early recovery of muscle strength.

[0002]

[Prior Art]

 Conventionally, cold therapy and hyperthermia are known as a kind of therapy for the above-mentioned various diseases. Cold therapy is easier and quicker to administer than hyperthermia, and has the excellent characteristics of immediate effect and long duration. In particular, a good therapeutic effect is obtained when massage is performed while cooling at −18 ° C.

[0003]

[Problems to be solved by the device]

 By the way, conventional methods used for cryotherapy include what is called an ice pack in which ice and water or ice and salt are put in a rubber bag, and an ultra-low temperature gas ejection device. It is necessary to make it each time, and the ultra-low temperature gas injection device has a problem that the device is large and the operation is troublesome. On the other hand, none of the conventional means has portability and can be used for both cold therapy and hyperthermia.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a massage pack that is portable and that can perform cryotherapy and hyperthermia extremely easily. There is.

[0005]

[Means for Solving the Problems]

 The massage pack according to claim 1 is characterized by comprising an antifreeze solution produced by adding alcohol and water to carboxymethylcellulose, and a flexible container for containing the antifreeze solution. A massage pack according to a second aspect is characterized by comprising an antifreeze solution obtained by adding a solution in which talc is dispersed in carboxymethylcellulose in place of the antifreeze solution according to the first aspect. The massage pack according to claim 3 is characterized in that the antifreeze solution according to claim 1 or 2 is mixed with particles of a superabsorbent polymer which has been prehydrated.

[0006]

[Action]

 According to the massage pack of claim 1, by using carboxymethylcellulose as a medium of the antifreeze liquid, it is possible to maintain an appropriate viscosity even at a practically low temperature, and a large specific heat. A heat storage effect is also obtained, and a long-term cooling effect is obtained. Moreover, since the specific heat is large, a long-term heating effect can be obtained when heated. According to the massage pack of claim 2, by mixing the antifreeze solution of claim 1 with a solution in which talc is dispersed in alcohol, a more pleasant viscosity can be obtained. According to the massage pack of claim 3, by mixing the particles of the superabsorbent polymer previously hydrated with the antifreeze solution according to claim 1 or 2, the heat storage effect is further enhanced and the cooling effect is improved. And the thermal effect lasts longer.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the external appearance of a massage pack according to an embodiment of the present invention. In this figure, a massage pack has a flexible container 1 formed in a rectangular shape and a sheet-like heat insulating member 2 attached to one surface (the upper surface in this drawing) of the container 1. It is configured to have.

The container 1 is made of a material having a mechanical strength that does not impair the flexibility even at about −20 ° C. and sufficiently withstands friction during massage. As this material, a polymer material, a rubber member, or a synthetic member in which a rubber member and a fiber are combined is suitable.

On the other hand, the container 1 is filled with an antifreeze liquid 3 (see FIG. 2). This antifreeze liquid 3 is the most important one for the massage pack to function, and the main functions required are as follows. Maintaining an appropriate viscosity even at a practically low temperature (eg, -15 ° C to -18 ° C). It has a large specific heat and stores heat. Low toxicity.

In the present invention, carboxymethyl cellulose (also known as: cellulose glycolic acid ether sodium salt) is used to satisfy the conditions (1) to (3). Alcohol is added to this and dispersed, and then water is added to form antifreeze 3.

As an application example of this antifreeze liquid 3, a mixture of talc (or talc) in which alcohol is dispersed is mixed. The addition of this talc further improves the feel of contact with the skin. Further, particles of a superabsorbent polymer (for example, vinyl alcohol / acrylic acid copolymer) in which water is absorbed in advance are mixed in any of the above antifreeze solutions 3. In this case, as shown in FIG. 3, the water absorption rate and the mechanical strength of the particles are inversely proportional to each other, so that if a large amount of water is absorbed, the mechanical strength will decrease. Therefore, the amount of water contained is set to about 50%. By using the particles of the super absorbent polymer, the heat storage effect is improved, and the cooling effect and the heat effect are maintained for a long time.

In FIG. 2, the heat insulating member 2 is made of a porous and flexible material, and urethane foam is preferably used as this material. When the massage pack having the above structure is used as a cold therapy, it should be placed in a freezer or the like in advance and sufficiently cooled. Then, at the time of use, after the surface on the side where the heat insulating member 2 is not provided is applied to the affected area, the container 1 is moved back and forth and left and right to massage the affected area. As a result, the affected area is cooled. On the other hand, when using it as hyperthermia, put it in hot water etc. and heat it sufficiently. At the time of use, the same operation as described above is performed.

Next, FIG. 4 is a perspective view showing an application example of the massage pack. As shown in FIG. 4, a plurality of flexible spherical containers 4 filled with the antifreeze liquid 3 are provided. 4 and a flexible sheet-like partition plate 6 for arranging these containers 4, 4 in a grid pattern. The shape of the containers 4, 4, ... Is not limited to a spherical shape and may be a polygonal shape. The partition member 5 can be omitted by forming it into a polygonal shape.

FIG. 5 is a perspective view showing another application example of the massage pack, and FIG. 6 is a side view thereof. In this application example, a belt having a heat insulating function, that is, a mounting belt 6 for an affected area is attached instead of the heat insulating member 2. Further, a surface fastener 7 having a convex surface is attached to one of both ends of the back surface of the belt 6, and a surface fastener 8 having a concave surface is attached to the other. In addition, in the above-mentioned embodiment, the heat insulating member 2 is used to prevent the body temperature from being transmitted to the inside of the container 1. The member 2 may be used instead. Alternatively, instead of pasting the heat insulating member 2 in advance, a separately prepared heat insulating member may be used at the time of use, and the affected area may be massaged while being covered with the heat insulating member.

[Effect of the device]

 As described above, according to the massage pack of the present invention, since the antifreeze liquid produced by adding alcohol and water to carboxymethyl cellulose and the flexible container for containing the antifreeze liquid are provided, it is easy to carry. It is both easy and extremely easy to carry out cryotherapy and hyperthermia. Further, by adding a solution in which talc is dispersed in alcohol to the above antifreeze solution, the feeling of close contact with the skin is further improved. In addition, the heat storage effect is further improved and the cooling effect and the heat effect are sustained for a long time by setting the superabsorbent polymer which has been previously hydrated in any of the above-mentioned antifreeze liquids in a proper shape and mixed.
