An exercise device is provided with a first element disposed at a first side and a second element disposed at a second side. The first element includes gripping features to prevent skidding or sliding of exercise device when first element is abutting a surface. The second element includes sliding features to facilitate sliding of exercise device when second element is abutting the surface. Thus, when an exercise practitioner desires to use the exercise device to prevent movement of a particular body part against the surface, the practitioner places the first element against the surface. Conversely, when the exercise practitioner desires to use the exercise device to facilitate movement of a particular body part against the surface, the practitioner places the second element against the surface. The exercise device further includes an insert which may be removed and heated or cooled to provide heating or cooling pad/pack to a body part.

Provided is a heating body that enables high-speed production using a conventional rotary heat-sealing roll, has a wearing portion with sufficient strength to use by inserting a hand or the like, thereby being used safely and conveniently, and can be worn on the body or the like without being adhered thereto, and a method for producing the same. An example of one aspect of the present invention is a heating body in which a heat-generating composition that generates heat in the presence of air is accommodated in a bag body formed by heat sealing a one-surface side laminated base material comprising a first base material and a second base material, and a covering material, at a peripheral edge portion thereof, characterized in that: the first base material has one surface being a nonwoven fabric layer and the other surface being a heat sealable resin layer; the second base material is a sheet in which an olefin-based nonwoven fabric layer and a resin film are laminated using an olefin-based resin; the first base material and the second base material are capable of forming a space into which a body part can be inserted or held, in a part surrounded by the peripheral edge portion; and in a heat sealed part of the bag body peripheral edge portion, the heat sealable resin layer of the first base material and the nonwoven fabric layer of the second base material are bonded together, and the resin film of the second base material and the covering material are bonded together; as well as a method for producing the same.

A hot and cold pack for breast treatment for pregnant women is provided. The hot and cold pack for breast treatment for pregnant women includes a cover including a through hole in a center thereof, through which a user's nipple passes, and having an annular shape of which a portion is open to adjust a size according to the size of a user's breast while wrapping and covering the user's breast, a thermal insulating material filled inside the cover, and a length adjustment unit provided in the open portion of the cover to connect both sides of the open cover, and adjusting the size of the cover.

Proposed is an oral cooling device using a cooling balloon, including: a cooling water supply portion provided with a cooler that cools cooling water and a pump that supplies and recovers the cooling water; a cooling water hose portion connected to the cooling water supply portion to transfer the supplied cooling water and recover the recovered cooling water to the cooling water supply portion; and a cooling balloon portion which is connected to an end portion of the cooling water hose portion, expands by the supplied cooling water to cool an inside of an oral cavity of a patient after being inserted into a mouth of the patient, and contracts in a case where the cooling water is recovered to the cooling water supply portion.

There is provided a health promoting device (10) which consists of a bag (11) having a sealed cavity (13) which is at least partly filled with soapstone powder. The bag may be made of an elastomer material.

The purpose of the present invention is to provide a heat generator that comprises an adhesive layer containing a volatile component and in which the volatile component is maintained in a stable state during storage, the volatile component is prevented from adhering to a heat-generating section, and it is possible to achieve an excellent warming effect during use. This heat generator comprises: a heat-generating section, an accommodation body that accommodates the heat-generating section and comprises an attachment surface to which an attachment body is attached, an adhesive layer provided to the attachment surface side of the accommodation body, and a release sheet provided to the attachment surface side of the adhesive layer. As a result of including a volatile component in the adhesive layer and providing a metal foil membrane to the release sheet, it is possible to maintain the volatile component in a stable state within the adhesive layer during storage. It is thereby possible to prevent the adhesion of the volatile component to the heat-generating section during storage and to achieve an excellent warming effect during use.

The purpose of the present invention is to provide a heat generator that contains a volatile component and in which the volatile component is stably maintained during storage, the volatile component is prevented from adhering to a heat-generating section, and it is possible to achieve an excellent warming effect during use. This heat generator comprises a heat-generating section (1), an accommodation body (2) for accommodating the heat-generating section (1), an adhesive layer (3) provided to an attachment surface side of the accommodation body (2), and a release sheet (4) provided to the attachment surface side of the adhesive layer (3). As a result of including a volatile component in the adhesive layer (3) and respectively providing gas barrier layers (211), (41) to a first packaging material (21) constituting the attachment surface side of the accommodation body (2) and to the release sheet (4), it is possible to stably maintain the volatile component within the adhesive layer (3) during storage. It is thereby possible to prevent the volatile component from adhering to the heat-generating section (1) during storage and to achieve an excellent warming effect during use.

Disclosed is a system which employs a cooling or heating pad which is preferably a thin, flexible pad for placement at an intended area of the body. The pad includes a layer of highly conductive material which can be cooled or heated using a portable source of heat or cold material delivered to the conductive material by a delivery conduit. Valves can be included to regulate flow of the cooling or heating material from the source to the pad. The system can also include a dual-chambered canister for containing two different media for heating, cooling or for alternating heating and cooling the pad.

A gel-pack has a plurality of self-contained components organized as layers in an interior chamber of the gel-pack. Each layer may be inserted into, and removed from, the interior chamber individually. The components include a solid-state gel layer that stores thermal energy, a first radiant energy barrier that prevents the transfer of thermal energy radiating from an exterior of the gel-pack into the solid-state gel layer, and a second radiant energy barrier that reflects the thermal energy radiating from the user's body into the solid-state gel layer.
