Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a medical mat, and promotes blood circulation of the whole body during sleep by absorbing radiant energy from a far-infrared radiator through the outer surface of the skin of a human body. The present invention relates to a medical mat which has a hot compressing effect.

[0002]

2. Description of the Related Art The applicant first forms a printed pattern on the outer surface of a woven or nonwoven fabric with an ink containing a powder of a far-infrared radiator, and absorbs the far-infrared rays emitted from the printed pattern on the human body. Thereby, a functional sheet for bedding that promotes blood circulation throughout the body during bedtime, and forming irregularities on the outer surface of the coating film forming the printed pattern,
A functional sheet that increases the total amount of far-infrared radiation energy by increasing the area of the outer surface of the coating film has been developed and disclosed (Japanese Patent Application No. 8-1489).
No. 69, Japanese Patent Application No. 9-171523, etc.).

When the functional sheet is used for bedding or the like, the ceramic powder in the ink constituting the printed pattern is heated by the human body temperature, and is activated by absorbing thermal energy due to the body temperature. As a result, far-infrared rays are re-emitted from the activated ceramic powder, and the re-emitted far-infrared rays are absorbed into the outer surface of the human skin to promote blood flow and nerve transmission. The activation of the system and the like are achieved, and the re-emitted far-infrared energy is directly absorbed by the affected area, so that the hot compress effect is given to the affected area.

[0004] As described above, the functional sheet developed earlier by the applicant has excellent practical utility. However, there are still many problems to be solved in the above-mentioned conventional functional sheet, and the most problematic point is that the powder of the far-infrared radiator fixed to the sheet absorbs human body temperature energy. The powder is not highly activated due to the low ratio, and as a result, the total amount of far-infrared energy re-emitted from the powder is small, and a remarkable blood flow promotion and warm compress effect can be achieved within a short period of time. There is a drawback that you can not do it.

In other words, when a conventional functional sheet is used for bedding, it is simply laid on a mattress or used as a cover for a comforter, so that it is transmitted from the human body to the functional sheet. Heat due to body temperature is easily transmitted through the functional sheet and into the mattress or the like. As a result, the rate at which thermal energy due to body temperature is absorbed by the powder of the far-infrared radiator fixed to the functional sheet becomes extremely low, and 70% to 80% of the body temperature energy is not absorbed into the powder. Then, it is released as heat loss into the mattress or the like.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem in the case where such a conventional functional sheet is used for bedding, that is, the heat energy due to body temperature causes the far-infrared radiant body to adhere to the sheet. The problem is that the absorption rate is relatively low, and the total energy re-emitted from the far-infrared radiator is low, so that significant blood flow enhancement and warm compress effect cannot be obtained. By organically combining a functional sheet body to which the powder of the far-infrared radiator is fixed and a mat body having thermal insulation, the thermal energy due to the human body temperature can be effectively and efficiently used. An object of the present invention is to provide a medical mat which can be absorbed by powder to thereby provide an excellent blood flow promoting action and a hot compress action, and which can significantly reduce the production cost.

[0007]

According to the first aspect of the present invention, there is provided a far-infrared radiating ceramic which emits far-infrared rays having a wavelength of 8 μm to 20 μm at a high emissivity of 85% or more at a temperature of 30 ° C. to 40 ° C. A basic structure of the present invention includes a sheet body to which powder is fixed and a heat-insulating mat body combined with the sheet body.

According to a second aspect of the present invention, in the first aspect of the present invention, the sheet is formed of any one of a woven fabric, a nonwoven fabric, a synthetic resin film, and a rubber film.

According to a third aspect of the present invention, in the first aspect of the present invention, the mat body is formed of any of foamable resin, cotton, and feathers.

According to a fourth aspect of the present invention, in the first aspect of the present invention, the sheet member is fixed by coating, printing or impregnating a far-infrared radiation ceramic.

According to a fifth aspect of the present invention, in the first aspect of the present invention, the sheet body is detachably fixed to one side of the mat body.

According to a sixth aspect of the present invention, in the first aspect of the present invention, the sheet member is integrally fixed to one side of the mat member.

According to a seventh aspect of the present invention, in the first aspect of the present invention, the sheet is a part of a cover member forming a mat body.

In the present invention, since the sheet body and the heat-insulating mat body are combined, heat due to the human body temperature passes through the sheet body and is hardly absorbed into the mat body. As a result, most of the heat due to body temperature is effectively absorbed by the far-infrared radiation ceramic powder that is effectively fixed to the sheet,
By activating this more highly, the amount of radiant energy of far infrared rays emitted from the ceramic powder increases.

The far-infrared rays emitted from the activated powder are absorbed into the outer surface layer of the skin of a person lying on the sheet with high efficiency, and the capillaries and the nerve transmission system due to energy absorption are absorbed. By the activation, the same effect as when a massage or the like is received is induced. In addition, according to the functions of the functional powders contained in the mixture, effects such as warming (heating), promoting blood flow, and antibacterial effects are exhibited.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of a medical mat A according to the present invention.

Further, in the present embodiment, the sheet body 1 is a woven cloth. However, it is needless to say that the sheet body 1 may be a nonwoven cloth made of natural or synthetic fibers, or may be made of a synthetic resin film.

The coating layer 2 fixed to the sheet body 1 is formed from a mixture mainly composed of fine powder of a far-infrared radiator. In the present embodiment, the coating layer 2 has a thickness of 8 μm at a temperature of 30 ° C. to 40 ° C. A mixture is formed from a powder of a ceramic far-infrared radiator that emits far-infrared rays having a wavelength of ２０20 μm at an emissivity of about 85% or more, and a synthetic resin adhesive. The amount of the mixture applied to the sheet 1, that is, the weight of the far-infrared radiator powder in the coating layer 2 is selected to be 20 gr or more per unit area of the sheet 1.

In this embodiment, an adhesive is used as a base of the mixture, but ink or paint may be used instead. Further, the mixing ratio of the adhesive to the powder of the far-infrared radiator is selected to be about 20 wt% to 50 wt%. If the amount of the adhesive is increased, the powder of the far-infrared radiator is buried in the adhesive, and the amount of the radiated far-infrared radiation absorbed by the human body decreases.

In addition, powders of other functional inorganic substances such as tourmaline, piezoelectric ceramics, antibacterial metals (titanium oxide, copper oxide, etc.), radioactive metals (thorium oxide, radium oxide, etc.) and the like can be added to the mixture. One or more powders may be mixed. By mixing powder of tourmaline and piezoelectric ceramics, the lines of electric force and lines of magnetic force act on the components in blood and body fluid, and the blood circulation promoting action is further enhanced. It has been found that the optimal mixing ratio of the functional inorganic substance powder to the far-infrared radiator powder is 10 wt% or more, preferably about 10 wt% to 30 wt%.

Further, carbon powder may be mixed into the mixture alone or together with another functional inorganic substance. The mixing ratio of the carbon powder to the powder of the far-infrared radiator is 5 wt% or more, preferably 5 wt% to 10 wt%.

In addition, an appropriate amount of a foaming agent may be mixed into the mixture alone or together with a powder of another functional inorganic substance. As the foaming agent, a foaming agent which does not foam during the application of the mixture, foams in the drying process of the coated film after application, and forms irregularities on the surface is advantageous. In this method, a low-boiling hydrocarbon such as benzol is used and heated and vaporized in a drying step of the coating film to form irregularities due to foaming on the coating film surface. By forming the irregularities, the outer surface area of the coating film increases, and the amount of energy radiated into the skin of the human body increases.

In the first embodiment shown in FIG. 1, the powder of the far-infrared radiator, which is the main agent, has a wavelength of 8 μm to 2 μm.
Using a powder of Biomate (ceramic far-infrared radiator manufactured by Nisshin Kogyo Co., Ltd.) that emits far-infrared energy having a peak value within a range of 0 μm at an emissivity of 85% or more, and bonding the powder to an epoxy resin The mixture with the agent is applied and solidified on the outer surface of the sheet body 1 made of nonwoven fabric by a so-called printing system, but the method of fixing the far-infrared radiation ceramic powder to the sheet material may be any method. In addition to the above-described coating method (or printing method), the far-infrared radiation ceramic powder may be fixed to the sheet material using a coating method or an impregnation method.

Further, a powder of a far-infrared radiator or a mixture of a powder of a far-infrared radiator and a powder of a functional organic substance is sprayed and sandwiched between two thin sheet materials containing a thermoplastic resin. By compressing and heating the sheet material from the outer surface, the sheet material and the powder of the far-infrared radiator may be fixed and integrated to form the sheet body 1.

High 8
Far-infrared rays in a wavelength range of ２０20 μm are emitted with an emissivity of 85% or more, and most of the emitted far-infrared energy is efficiently absorbed into the human body. Thereby, the blood circulation (blood flow) of the human body is remarkably promoted, and the effect of the warm compress on the human body is enhanced, and the same effect as that in the case of receiving a so-called massage is exerted by activating the capillaries and the nerve transmission system. In addition, by changing the powder of the functional inorganic substance to be mixed, an arbitrary function such as heat retention, deodorization, and antibacterial can be imparted to the sheet body, and a medical mat can be manufactured at low cost. The present invention has excellent practical utility as described above.
