【Example】

 Hereinafter, a specific embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the medical heat retention tool 1 according to the present invention is formed by dispersing bags that generate heat by utilizing an oxidation reaction.

That is, the heating bag is formed by using a non-woven fabric, in which a predetermined amount of metal powder such as iron powder, water, wood powder, activated carbon, and salt are mixed to utilize the oxidation reaction. It then generates heat. Such heating bag bodies 2 are dispersed vertically and horizontally on the same plane, and in the present embodiment, the overall shape is a quadrangle. Then, the size of the heat-generating bag 2 dispersed in a large number is determined in consideration of the affected area, adults, infants, or the like.

As shown in FIGS. 1 and 2, each of the plurality of heat-generating bag bodies 2, 2 and 2 is formed with a connecting portion 3 for connecting each one at an outer peripheral portion thereof. Become. Therefore, by bending the connecting portion 3, it is possible to easily obtain a heat retaining tool matching the shape of a diseased portion such as a joint. In this embodiment, the heat-generating bag 2 contained in the non-woven fabric is dispersed, but the connecting portion 3 between the bag bodies may be made of only the connecting portion 3 having high elasticity.

In addition, as shown in FIG. 2, a void 5 that is a large cut is formed in a central portion formed when the heating bag bodies 2 are arranged on a plane. The void 5 is combined with the connecting portion 3 to exert the expansion / contraction effect. Further, in the present embodiment, notches 4 may be further formed in each of the connecting portions 3 so that the connecting portions 3 can be cut more easily.

Further, as shown in FIG. 3, a sheet member 6 is attached to the back surface side of each of the dispersed heat-generating bags 2, and by peeling off the sheet member 6, the inside of the heat-generating bag 2 is removed. Oxygen is supplied to each of the heating bag bodies 2 to generate heat. The sheet member 6 is provided with a coating material attached to one surface of each of the dispersed heat generating bag bodies 2, and is detachably provided thereon. It should be noted that it is preferable to form a notch 7 in the sheet member 6 so as to correspond to the connecting portion 3 of the heating bag body 2.

In addition, in the above-mentioned embodiment, the dispersed heating bags 2 are formed in a square surface shape, but the shape is not limited to such a quadrangular shape, but may be a round shape, a triangular shape, or the like. It may have a shape.

When actually using the medical heat retaining device 1 of the present invention having the above-mentioned configuration, as shown by S in FIG. 1, the medical heat retaining device 1 is fitted to an affected area such as neuralgia or rheumatism, It cuts out using the said connection part 3. In this case, if the notch 4 is further formed in each of the connecting portions 3, the cutting can be performed more easily.

When the knee is the affected part, as shown in FIG. 4, the medical heat retention tool 1 having a predetermined shape is obtained by cutting it from the connecting part 3 according to the size of the affected part. .. After that, the sheet member 6 attached to the back surface of the heat retaining tool is peeled off and attached to the affected area. Then, the metal powder such as iron powder in the heat-generating bag 2 comes into contact with air to cause an oxidation reaction and generate heat to heat the affected area. Therefore, simple heat retention can be performed as an alternative to a hot water bottle or a hot compress.

In this case, since the medical heat retention tool 1 of the present invention is formed by disposing a large number of heat generating bag bodies 2 in a small size as described above, a situation such as a low temperature burn like a conventional disposable body warmer. It is possible to obtain a suitable temperature state without causing Further, since the joint portion 3 is connected and the presence of the space 5 allows the joint portion such as a knee or an elbow to be attached in conformity with the shape of the joint portion, it is not easily peeled off as in the conventional case.

Next, in the case of brachial neuralgia (neck, pain from shoulder to hand) and the like, as shown in FIG. 5, the upper arm is cut from the connecting portion 3 into a predetermined shape according to the affected part of the shoulder. Obtain the heat-retaining device 1 for medical use that matches the shape of the part, and apply it to the affected part. Then, the metal powder in the heat-generating bag 2 comes into contact with air to cause an oxidation reaction to warm the affected area, but due to the presence of the void 5 as well as the connection of the connecting portion 3, the movement of the arm is fitted. Does not come off easily.

When the knee or the like is relatively narrow, the connecting strength of the connecting portion 3 of the medical heat retaining tool 1 is strengthened, and the void 5 is formed to be large, while the shoulder and the like are relatively small. If it is wide, it is advisable to weaken the connecting strength of the connecting portion 3 of the medical heat insulating tool 1 and to make the gap 5 small. From this point of view, if various kinds of heating bags 2 such as the size of the heat generating bag 2, the strength of the connecting portion 3 and the size of the void 5 are prepared in advance, the heat can be kept in accordance with the position and symptoms of the affected area. It will be possible.

Further, since it is formed in a small number in a dispersed manner, it is suitable for use not only for medical purposes but also for cold protection of children.
