2. Description of the Related Art For example, to alleviate pain and fever caused by mastitis and mastitis in a woman (partum woman) after childbirth, or
Cooling the breast or its vicinity has been performed for the purpose of weaning of breast milk at the time of switching from breast milk to baby food. Conventionally, as a cooling method in the above case, a compress using potatoes as a main material, a compress using glue, or the like has been used.

[0003] A poultice mainly composed of potatoes is obtained by mixing ground potatoes, mixing flour, chicken eggs and the like, kneading the mixture, and applying it to gauze. The compress using glue is obtained by taking a suitable amount of a commercially available glue, for example, starch glue, wrapping it in a plastic wrap, freezing it in a freezer or the like, and using it as a cooling tool.

[0004] The above-mentioned potato-based compress is heated at body temperature during use, and the potatoes and eggs, which are raw materials, decay and give offfensive odors. Sometimes it got worse.

[0005] A compress using the above-mentioned commercially available paste contains a preservative such as formalin to prevent the decay of the starch paste used, and there is a concern that it may adversely affect the human body. In addition, these compresses are made by nurses at hospitals and the like with time, leading to an increase in costs.

However, commercially available cooling
There is no means for fixing the heating equipment to parts of the human body that require cooling and heating, and therefore the cooling and heating effect is not sufficient because the installation position is shifted during daily activities. Was.

[0008] Further, in the cooling / heating treatment, there is an individual difference in the use temperature and the treatment temperature, and it is preferable that the cooling / heating temperature can be adjusted. Care has not been taken.

[0009] Further, most of the above-mentioned obstetrics and women who need a cooling / warming tool are for about one or two days, and thereafter become unnecessary. For such short-term use, it is wasteful for each person to purchase a cooling / heating device, and there is also a problem with the disposal of the cooling / heating device that is discarded. I was

[0010] Furthermore, after giving birth, the woman starts menstruation again. In the case of a woman with severe menstrual pain, her pain is relieved by warming her belly. In such a case, the cooling / heating device is warmed and used. However, if the heating / heating device is overheated, the soft plastic bag may be ruptured due to expansion of the enclosed cooling / heating medium.

(Object of the Invention) It is therefore an object of the present invention to provide a cooling / warming device capable of appropriately cooling or heating a portion requiring cooling or heating.
It is another object of the present invention to provide a cooling / heating device capable of adjusting a cooling or heating temperature. Still another object of the present invention is to provide a cooling / heating device that can be used efficiently. Still another object of the present invention is to provide
An object of the present invention is to provide a cooling / warming device that prevents damage to an envelope due to heating. Other objects of the present invention are:
It will be clear from the description below.

[0012]

Means of the present invention to solve the above problems and achieve the object are as follows. In the first invention, the cooling / heating body is provided, and the cooling / heating body is housed in a detachable manner, and a bag body having an adhesive portion on an outer surface thereof is provided. The warm body is provided with a cold storage heat agent capable of storing and storing heat and a wrapping body containing the cold storage heat agent, wherein
It is a heating tool.

According to a second aspect of the present invention, the bag is provided with a heat conduction alleviating layer for preventing a human body part from being overcooled or overheated by a cooling / heating body. It is a human body part cooling / warming tool according to the invention of the above.

In the third invention, the cooling / heating body is
A cooling / warming tool for a human body part according to the first or second aspect of the present invention, wherein a thin-walled portion or an antifreezing portion is provided, which can bend even when the cold storage agent solidifies by cooling. .

A fourth aspect of the present invention is characterized in that the shape of the cooling / heating body and the bag is ground paper, and a plurality of the cooling / heating bodies and the bag form an annular shape having a hole in the center portion. A cooling / warming tool for a human body part according to the first, second or third invention.

According to a fifth aspect of the present invention, there is provided a cooling / heating apparatus for a human body part according to the first, second, third or fourth aspect, wherein a pressure regulating valve is provided on the envelope. It is a warming tool.

In the present invention, examples of the adhesive used for the adhesive portion include natural rubber, polyisoprene rubber, styrene-butadiene copolymer rubber, and styrene-isoprene-
A kneaded product of a polymer such as a styrene copolymer or a styrene-butadiene-styrene copolymer is used.

In the present invention, examples of the regenerative heat storage agent include a polymer water-absorbing resin which absorbs water, swells and gels upon contact with water. As the polymer water-absorbing resin having such properties, those which are safe even when in contact with the human body are preferable, for example, graft-polymerized starch-based, carboxymethylcellulose-based, polyacrylic acid-based, and poval-based resins. No. Usually, a carboxymethyl cellulose system is used. The polymer water-absorbing resin is not limited to the above.

In order to improve the physical properties of the gelled product, potassium alum or the like can be used as a gelling accelerator. In order to prevent freezing of the cold storage agent, ethylene glycol, diethylene glycol, propylene glycol, ethylene glycol monobutyl ether, hexylene glycol and the like can be used. Since the gelled material using the antifreeze does not harden even when cooled, the cold storage agent layer can be applied closely along the shape of the part of the human body to be cooled.

In the present invention, as a material constituting the heat conduction relaxation layer, a polymer foam such as a polyurethane sponge or a non-woven fabric is used. In addition, the thickness of the adhesive portion is increased, or the thickness of the side of the wrapping body containing the cold storage agent that is applied to the portion of the human body is increased to further cool or heat the cooling / heating body. It can be controlled and gentle.

In the present invention, as the material of the bag, a non-woven fabric or the like used for a so-called disposable body warmer or the like is suitably used. As the nonwoven fabric, for example, a material made of cotton, recycled cellulose fiber, polyamide fiber, polyester fiber, or the like is used. Further, an antibacterial agent such as titanium metal or silver can be applied to the bag.

(Operation) Cooling and cooling for a human body part according to the present invention.
The heating tool has an adhesive portion on the outer surface of the bag body that houses the cooling / heating body, and can be adhesively fixed to various parts of the human body by attaching it to a place where cooling or heating is required.
Therefore, the cooling / heating effect can be maintained without the fixed position being shifted during daily activities. When a release sheet is attached to the surface of the adhesive portion of the bag body, it does not adhere to other objects even when touched, so that storage and handling are easy. Further, the adhesive portion can be fixed to the underwear with the adhesive portion facing the underwear side.

Since the cooling / heating device has a structure in which the cooling / heating member is inserted into and removed from the bag, the bag and the cooling / heating member must be purchased separately and used separately. Is possible.
Therefore, the cooling / heating device which has become unnecessary after being used for treatment can be taken out of the cooling / heating body from the bag, stored in a new bag, and reused. As described above, since a single cooling / heating body can be used by a plurality of patients, the patient only needs to purchase bags, and the economic burden is reduced. In addition, even if the cooling / heating device is not used, it is not necessary to discard the entire cooling device. Only the bag is discarded, and the disposal problem when discarded is reduced.

Further, even if breast milk or the like adheres to the bag and germs are generated at the place where the breast milk adheres, the cooling / heating body is taken out of the bag and replaced with a new bag to re-enter the bag.
It can be used in a fresh state, and the germs do not spread to other parts, and it is hygienic. By applying an antibacterial agent to the surface of the bag, it is possible to prevent an increase in germs and the like even if breast milk or the like adheres to the bag.

If the bag is provided with a heat conduction alleviating layer for preventing the body part from being excessively cooled or heated by the cooling / heating body, the thickness of the heat conduction alleviating layer or the material may be changed. By doing so, there is no danger of injury due to excessive cooling / heating, and it is possible to adjust the temperature and cooling / heating suitable for each individual, and to comfortably relieve pain and fever in a human body part.

A cooling / heating body provided with a thin portion or a non-freezing portion which can be bent even when the regenerator is solidified by cooling can be bent along the surface of the human body. Therefore, it is convenient to handle, and the whole can be stuck to the affected part, so that the cooling / heating effect can be maintained.

In the case where the shape of the cooling / heating body and the bag is ground paper, and a plurality of the cooling / heating bodies and the bag form an annular shape having a hole in the center portion, the breast may be cut off and the generation of various bacteria may occur. When pain and fever occur, the hole at the center can be worn over the entire breast except for the nipple and areola, and can be efficiently cooled without damaging the nipple and isola.

In the case where the pressure regulating valve is provided on the envelope,
For example, in the case where a cooling / heating body is placed in a microwave oven to heat a cold storage agent in order to hit the abdomen of a women with menstrual pain, heating proceeds and gas such as water vapor is generated from the cold storage agent in the wrapping body. Even when it starts to fill, the gas can escape to the outside of the envelope, and damage to the envelope can be prevented.

FIG. 4 is a cross-sectional view of a portion taken along the line II-II of FIG. 1, and the illustration of the cooling / heating body is omitted, and only the bag is shown.

The cooling / heating tool C for a human body part has a cooling / heating body 1 and a bag 2 in which the cooling / heating body 1 is removably accommodated. The cooling / heating body 1 and the bag 2 are both formed in ground paper shapes, and the bag 2 is formed slightly larger than the cooling / heating body 1. In addition, the cooling / heating body 1 and the bag body 2 are configured to have an annular shape when four to six linear portions 24, 24 are adjacently arranged adjacent to each other, as will be described later. It is preferable when cooling the whole breast. In addition, the number for forming an annular shape is not limited to the above number and can be set arbitrarily.

On the surface of the cooling / heating body 1, two groove-shaped thin portions 16, 16 are provided in the width direction. Further, one groove-shaped thin portion 16 is provided so as to be orthogonal to the thin portions 16. In addition, instead of the thin portion, an unfrozen portion can be formed in the portion.

The cooling / heating body 1 is configured by enclosing a cold storage agent 11 in a flexible envelope 12 (see FIG. 3). The envelope 12 is made of a laminated film of a polyamide film and a linear low-density polyethylene. The cold storage agent 11 is composed of a mixture of water, carboxymethyl cellulose as a gelling polymer water-absorbing resin, propylene glycol as an antifreeze, potassium alum as a gelling accelerator, and the like.

The bag 2 is made of a polyester fiber non-woven fabric. On one surface of the bag 2, a heat conduction relaxation layer 21 made of polyurethane sponge is provided. On the outer surface of the heat conduction relaxation layer 21, a layer of an adhesive portion 22 made of polyisoprene rubber is provided. Although not shown, a release sheet made of, for example, polypropylene is attached to the outer surface of the adhesive portion 22.

The cooling / heating body 1 is inserted into or taken out of the bag 2 through an insertion port 23 formed in an arc portion outside the bag 2. The surface of the bag 2 is treated with an antibacterial agent.

(Operation) The operation of the cooling / warming device for a human body part will be described by taking as an example the case where a woman gives birth to a baby after weaning a baby. FIG. 5 is a side view for explaining the case where the milk is cut using the cooling / heating tool for a human body part. The cooling / heating body 1 is taken out of the bag body 2 (may be stored in the bag body), placed in a refrigerator (freezer), and the regenerator 11 is cooled.

The cooling / heating body 1 is put into the bag 2 through the insertion opening 23, a release sheet (not shown) of the bag 2 is removed, the adhesive 22 is exposed, and the adhesive 22 is placed on the surface of the breast M. Then, 4 to 6 pieces are arranged in an annular shape around the areola N.
The cooling / heating device C arranged in an annular shape has a substantially circular hole 3 at the center. The hole 3 is usually set to have a diameter of 4 cm or more so as not to contact the areola N.

At the time of milking as described above, even if mother's milk comes out of the nipple and adheres to the bag 2 of the cooling / heating device C and becomes dirty,
The cooling / heating body 1 can be taken out of the bag 2 and replaced with a new bag 2 for use. Therefore, even if the cooling / heating tool C in which the cooling / heating body 1 is replaced with the new bag body 2 is used while being applied to the breast M again, the germs will not spread to other parts of the breast M. Extremely hygienic. Further, since the bag 2 is treated with an antibacterial agent, it is possible to prevent an increase in germs.

Since the heat conduction relaxation layer 21 is interposed between the cooling / heating body 1 and the breast M, the bag 2 can be used comfortably by preventing the breast M from being excessively cooled. In addition,
If a plurality of types having different thermal conductivity can be appropriately selected by changing the thickness and the material of the thermal conduction relaxation layer 21, the heating / cooling temperature can be adjusted for each patient. Further, since the bag body 2 is provided with the adhesive portion 22, it can be adhered and fixed to the surface of the breast M. Since the bag body 2 is a non-woven fabric, the bag body 2 has appropriate heat insulation properties, and can prevent the breast M from being overcooled together with the heat conduction relaxation layer 21.

Since the cooling portion 1 has the thin portion 16, even if each cooling / heating body 1 is cooled and loses its flexibility or becomes somewhat smaller, it is bent by the thin portion 16 to obtain the shape of the surface of the breast M. Cooling for human body parts
The heating tool C can be tightly fixed to the surface of the breast M.

In the treatment of secondary milk generated under the armpits, a human body part cooling / warming tool C is used by appropriately adhering and fixing the accessory breast part of several breasts M.
