疾患を予防できる。In the present embodiment, the substance that generates heat rays is coconut husk activated carbon that emits far infrared rays.
The present invention is not limited to this, and charcoal-based or coal-based carbides may be used, and far-infrared radiation ceramics or the like may be used in addition to activated carbon. Further, a disposable body warmer or the like that generates infrared rays may be used, but in this case, it is necessary to provide a storage portion in the recess 5 in order to allow the disposable body warmer or the like to be taken in and out. Further, it is preferable that the front cover body 21 is a mesh material that allows the far-infrared radiator 3 and the far-infrared radiator piece 42 to be visually recognized from the outside. By doing so, it is possible to visually recognize that the far-infrared radiation substance is used in the cushion 1 and thus the added value as a product can be improved. Further, the member used for the cushion member 4 is not limited to the hollow pipe piece 41 made of plastic, and may be a hollow pipe piece made of hard plastic or buckwheat hull. With these,
It does not easily get set and has excellent durability. Further, the shapes and sizes of the hollow pipe piece 41 and the far-infrared radiation piece 42 are not limited to those exemplified above. Further, although the front cover body 21 is a mesh-shaped knitted fabric piece and the back cover body 22 is a quilted cloth piece, the front cover body 21 and the back cover body 22 are formed from other knitted fabric pieces, cloth pieces, or the like. You may form. The cushion according to the present embodiment is not limited to use for hemorrhoid patients, but a healthy person without hemorrhoidal disease can effectively prevent hemorrhoidal disease by using it instead of a normal cushion.

とともに、衛生的に使用することができる。The cushion of the invention according to claim 1 is provided with a seating portion and a recessed portion recessed from the seating portion, and the recessed portion is made of a material that emits at least one of infrared rays and infrared rays. Since it is provided, the recess hardly presses the anus, and even a patient with hemorrhoids can sit comfortably. In addition, since far infrared rays and / or infrared rays are radiated from the depression to the anus, the affected area of hemorrhoids is effectively warmed and blood circulation is promoted, and as a result, the symptoms of hemorrhoids are relieved. You can In the cushion of the invention according to claim 2, since the recessed portion is formed to a depth that does not press the anus of the user when sitting, it is ensured that the recessed portion presses the anus when sitting. Since this can be prevented, the affected area of hemorrhoid is not pressed when sitting, and the person can sit comfortably. In the cushion according to the third aspect of the present invention, since the substance that emits at least one of far infrared rays and infrared rays is coconut husk activated carbon, it has a far infrared radiation action, an antibacterial action, and a deodorizing action peculiar to coconut husk activated carbon. Therefore, the far-infrared radiation effect can effectively warm the affected area of hemorrhoids to promote blood circulation, and prevent deterioration of hemorrhoids. Also, since the coconut shell activated carbon itself does not become hot, there is no risk of burns and it is safe. Furthermore, since the coconut husk activated carbon has an antibacterial action and a deodorizing action, the cushion can be used hygienically. Claim 4
