Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an exothermic hot compress. More specifically, it relates to a heat-generating compress for application to the affected area such as stiff shoulders and neuralgia.

[0002]

[Prior art]

 In conventional exothermic hot compresses, a base cloth is attached to one surface of a heating element that generates heat by chemically reacting with air and oxygen, and the non-heating element side surface of this base cloth is attached to the human skin. A pressure-sensitive adhesive layer for forming is formed. By applying this conventional heat-generating compress to the affected area such as stiff neck or neuralgia, the temperature around the affected area can be increased and the warming effect can suppress the pain in the affected area such as stiff neck or neuralgia.

[0003]

[Problems to be solved by the device]

 However, when the heating element generates heat, the temperature of the heating element may exceed the skin temperature and reach a high temperature of 50 to 55 ° C. When a conventional exothermic hot compress is applied to the skin, the pressure-sensitive adhesive layer becomes heat insulating. The high heat of the heating element is transmitted to the skin over the adhesive layer. For this reason, if the heat-generating compress is kept in contact with the skin for a long time, the skin temperature may rise to near the temperature of the heating element and the skin temperature may exceed 45 ° C. When the skin temperature reaches 45 ° C, the skin tissue is destroyed in about 6 hours, and when the skin temperature reaches 70 ° C, the skin tissue is destroyed in about 1 second. Also, if the skin temperature does not exceed 45 ° C, the heat will be felt naturally, but if the skin temperature exceeds 45 ° C, it will change to a painful warmth. Therefore, the conventional exothermic warm poultice has a problem that it may cause skin destruction or feel a painful temperature due to heat. In addition, when a heating element having a temperature higher than the body temperature is applied to the skin, the skin is burned at low temperature, and dermatitis symptoms such as erythema and blisters are exhibited. However, there is a problem that it also causes a decrease in body temperature.

In view of such circumstances, the present invention is to provide a heat-generating hot compress that can suppress pains such as stiff shoulders and neuralgia, prevent skin tissue destruction and dermatitis, and prevent low-temperature burns. To aim.

[0005]

A hot poultice in which a pressure-sensitive adhesive layer for sticking to human skin is formed, wherein a foam layer having high heat insulation is formed between the base cloth and the pressure-sensitive adhesive layer. Suru In the exothermic hot compress of claim 2, the base cloth is a non-woven fabric, the basis weight of the base cloth is 40 to 150 g / m ² , and the thickness of the foam layer is 0.1 to 0.3 mm, and the foam is formed. The expansion ratio of the layer is 1.2 to 3.0 times.

[Embodiment of device]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic sectional view of an exothermic hot compress according to an embodiment of the present invention. As shown in the figure, in the exothermic hot compress 10 of the present embodiment, the base fabric 2 is attached to one surface of the heating element 1 which generates heat by chemically reacting with air or oxygen. A foam layer 3 having a high heat insulating property is formed on the base cloth 2. Therefore, the heat generated by the heating element 1 can be blocked by the foam layer 3. A pressure-sensitive adhesive layer 4 for sticking to the skin of the human body is formed on the surface of the foam layer 3 on the non-heating element side, and a release paper 5 is temporarily bonded to the pressure-sensitive adhesive layer 4.

The heating element 1 generates heat by chemically reacting with air or oxygen, and a known material such as a pocket ash used for a portable pocket blast may be used. The base fabric 2 is a non-woven fabric and has a basis weight of 40 to 150 g / m.²The range is preferably 100 g / m ² The front and back are suitable. The basis weight of the base cloth 2 is 40 g / m²If it does not exceed the range, the heat insulating effect on the skin will be weakened and low temperature burns will occur, and the basis weight of the base cloth 2 will be 150 g / m²When it exceeds, the heat transfer effect on the skin is diminished and the warming effect on the affected area is not exhibited. The pressure-sensitive adhesive layer 4 may be formed by a known pressure-sensitive adhesive on the surface of the foam layer 3 on the non-heating element side by a conventional method. The release paper 5 may also be a known material without particular limitation. The foam layer 3 is made of foamed acrylic resin having excellent water resistance, acid resistance, alkali resistance and oil resistance, and has high heat insulation. The thickness of the foam layer 3 is preferably in the range of 0.1 to 0.3 mm, preferably about 0.2 mm, and the expansion ratio of the foam layer 3 is preferably 1.2 to 3.0 times, preferably about 2.0 times. If the thickness of the foam layer 3 does not exceed 0.1 mm, the heat insulation effect on the skin is weakened, causing low-temperature burns. If the thickness of the foam layer 3 exceeds 0.3 mm, the heat transfer effect on the skin is weakened and damage to the affected area occurs. No longer has a warming effect. Furthermore, if the expansion ratio of the foam layer 3 does not exceed 1.2 times, the heat insulating effect on the skin is weakened, causing low-temperature burns, and if the expansion ratio of the foam layer 3 exceeds 3.0 times, the collapse of the foam or the base material will occur. Adhesion to the cloth 2 is reduced, and the heat transfer effect on the skin is diminished, so that the warming effect on the affected area is not exhibited. That is, although the foam layer 3 has a high heat insulating property, when the heat generating element 1 reaches a high temperature, it blocks a part of the heat generated by the heat generating element 1, but hinders the warming effect of the heat generating element 1. Not a thing.

Next, a method of using the heat-generating hot compress 10 of the present embodiment will be described. First, in order to heat the heating element 1, for example, the exothermic heat compress 10 of the present embodiment contained in a sealed bag is taken out from the bag, and the release paper 5 is peeled off from the adhesive layer 4 to obtain the adhesive. The layer 4 is attached to the affected area such as stiff neck or neuralgia. Thereafter, the heating element 1 chemically reacts with air or oxygen to generate sufficient heat to warm the affected area described above, and the warming effect can suppress pain in the affected area such as stiff shoulders and neuralgia. Even if the temperature of the heating element 1 exceeds 45 ° C. and becomes higher than the skin temperature, the foam layer 3 is formed between the heating element 1 and the skin, so that part of the heat of the heating element 1 is generated. Is blocked by the foam layer 3 and does not cause skin tissue destruction or dermatitis. Of course, in the exothermic warm poultice 10 of the present embodiment, since part of the heat of the heating element 1 is blocked by the foam layer 3, it does not cause low temperature burns and does not cause a decrease in body temperature.
