Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a hot compress structure. In particular, the present invention relates to a hot compress structure that prevents the maximum temperature of the skin from exceeding a certain desired temperature when it is brought into close contact with the human body.

[Conventional technology]

Warm compresses are one of the treatment methods for neuralgia, rheumatism, lower back pain, etc., but the conventional warm compress treatment is
These include towels soaked in boiling water, konnyaku, etc., applied directly to the affected area, and compresses containing irritating substances such as chili peppers. However, the former treatment method using hot compress towels, konnyaku, etc. can only provide a hot compress state at high temperatures for a short time, and it is necessary to temporarily suspend daily life activities during the treatment. Furthermore, since the heat of vaporization is removed by the compress after the treatment, there is a possibility that the opposite effect will be brought about. In addition, the latter treatment method using irritating substances merely irritates the skin, and there is a possibility that skin disorders such as rashes and rashes may appear.

Furthermore, in order to fully obtain the therapeutic effect of a warm compress, it may be required to provide a constant level of warmth and retain heat. For example, when a hot compress structure is used in close contact with the human body, it may be necessary for the hot compress to maintain a constant skin temperature, for example, at a temperature not exceeding 40° C., for a long period of time.

However, the above-mentioned conventional hot compresses are not at all satisfied with this continuous heat retaining ability.

On the other hand, various types of disposable body warmers have been proposed and actually used. However, conventional disposable body warmers all have their temperature characteristics (relationship between time and temperature).
In particular, it is difficult to maintain a constant temperature for a sufficient period of time without exceeding a certain temperature.

In other words, with conventional disposable body warmers, the required temperature duration is short, or the temperature characteristics are difficult to control (even if you want to set a certain temperature and prevent it from exceeding it, such control is not possible). It was extremely difficult.

[Purpose of the invention]

An object of the present invention is to solve the above-mentioned problems of the prior art, and to control the skin temperature of a person so that it does not exceed a certain temperature when used in close contact with the human body. It is an object of the present invention to provide a hot compress structure that is easy to heat and can maintain a sufficient temperature for a sufficient period of time.

[Means for solving problems]

The present invention provides a hot compress structure comprising a heat-generating composition that generates heat in the presence of air inside a flat bag having a ventilation layer formed on one side and a compress layer formed on the other side. The layer has an air flow rate of 0.1~0.8X 10-4cc
・cm-"・sec-'・Torr-', and the maximum temperature of the skin when the hot compress structure is brought into close contact with the human body is any desired constant temperature within the range of 38 to 46°C. It has a structure that cannot be exceeded.

The hot compress structure of the present invention has an air permeability of 0.1 to 0.8X10-'cc Hcm-'' ・se in the ventilation layer as described above.
As a result of setting the temperature in the range of c −' ·Torr −', it is possible to prevent the temperature from exceeding a certain level, which was difficult in the past, and to obtain a stable and sufficient temperature duration.

In particular, in the present invention, by selecting an appropriate ventilation amount within the above ventilation amount range, when the hot compress structure is brought into close contact with the human body, the maximum temperature of the skin is within the range of 38 to 46°C. The structure is designed to prevent the temperature from exceeding a predetermined temperature, and this can be achieved based on the above-mentioned ventilation range.

The present invention will be explained as follows using FIG. 1 showing an embodiment of the invention which will be described in detail later.

The hot compress structure of the present invention, as illustrated in FIG. The ventilation layer 1 has a built-in composition 4, and the ventilation layer 1 has an airflow rate of 0.1 to 0.8X10-'cc・am-''・sec
-'・Torr-' and by selecting the ventilation amount within this range, the maximum temperature of the skin will be within the range of 38 to 46°C when the warm compress structure is brought into close contact with the human body. The structure is such that the desired degree of the difference is not exceeded.

The example shown in FIG.
The ventilation layer 1 was formed by the ventilation member 11 formed on the outside. Specifically, the microporous sheet 12 was laminated with the air permeable member 11 to form the sheet. However, of course, the breathable layer may be constructed only by the microporous sheet 12 without using the breathable member 11.

In order to prevent the maximum skin temperature from exceeding a desired constant temperature of 38 to 46°C when the hot compress structure of the present invention is used in close contact with the human body, the air permeability of the ventilation layer 3 is 0.1~0.8X10-4cc・cm-2・5ec-
The ventilation amount is preferably kept within the range of 0.28 to 0.5 x 10-'c
The range is preferably c.Cl11-'.8ec-'.Torr-'.

By setting the ventilation amount of the ventilation layer 3 within this range, when the thermal compress structure is brought into close contact with the human body, the maximum temperature of the skin can be reduced to 4.
It is now possible to easily control the temperature between 1 and 44°C, and the ideal duration can be satisfied.

Furthermore, the ventilation layer 1 or the microporous sheet 12 constituting this
Softness of 2.5g in loop stiffness tester
It is preferable that it is below. In this way, when the heat generating composition 4 absorbs oxygen, the ventilation layer 1 easily contracts.
This is advantageous because the surfaces of the heat generating composition 4 and the ventilation layer 1 are in close contact with each other, and the shifting of the heat generating composition 4 can be easily prevented. Also, increase the ventilation amount to 0.1 to 0.8 x 10-4cc/cm-”
The micropore diameter for controlling within the range of sec-'-Torr-' is preferably 15μ or less. When the micropore diameter is 15 μm or less, oxygen absorption is controlled, so that close contact between the heat generating composition 4 and the ventilation layer 1 can be easily maintained.

It is desirable that the poultice layer 2 contains moisture for good thermal conductivity and has excellent adhesiveness. In addition, it is desirable that the adhesive has appropriate bonding properties such that it softens even at temperatures of 38 to 46° C. during heat generation and does not leave a plaster for a compress on the skin.

For example, it is well known that CMC, sodium polyacrylate, water-absorbing resin, kaolin, gelatin, etc. are used as content materials to contain water, but in addition to these, base materials and chemical solutions suitable for hot compresses may also be used. You can let it happen.

〔Example〕

An embodiment of the present invention will be described below.

This embodiment is shown in FIG. 1, and the structure according to this embodiment has a ventilation layer 1 consisting of a ventilation member 11 and a microporous sheet 12 on one side, and a nonporous film 21 and a compress material on the other side. 2
This warm compress is constructed by incorporating a heat-generating composition 4 that generates heat in the presence of air inside a flat bag 3 formed as a compress layer 2 consisting of a compressive layer 2 consisting of a compressive material 5 and a compressive layer 2. This is further sealed in an airtight bag (2) to form a structure. The poultice member 25 formed on the outside of the non-porous film 21 is made up of a poultice base fabric 22, a poultice base material 23, and a poultice protective film 24 in order from the non-porous film 21 side.

A poultice base material 23, which is a plaster, is applied and formed on a poultice base cloth 22, which is a cloth, to form a poultice side surface.

When in use, the warm compress (2) is taken out from the airtight bag (2), the compress protective film 24 is removed, and the compress base 23 is brought into close contact with the affected area.

In order to ensure that the maximum temperature of the skin at that time does not exceed a desired constant temperature of 38 to 46 degrees Celsius, the amount of ventilation N1 is set to 0.1 to 0.
8 X 10-'cc acta-"φsec-'
・The configuration is such that it is kept within the range of Torr-'.

The results of an experiment using the structure of this example will be described below.

Actually, it was done as follows.

Using the structure shown in Figure 1, take out the hot compress ■ from the airtight bag ■, remove the compress protective film 24 of the compress layer 2, use two thermocouples on the compress base 23, and one In order to measure the heat generation temperature of the hot compress, one was attached to the affected area, with one attached to the poultice base 23 and the other attached to the skin. The temperature change at that time was recorded on 5BR187-35CA manufactured by Rika Kogyo Co., Ltd.

The test was conducted by changing the following measurement conditions (A) to (Force) to obtain temperature characteristics.

(a) Air flow rate of ventilation layer (b) Temperature/humidity storage area (x) Heat-generating composition (1) Weight of heat-generating composition (e) Poultice base material (force) Application site test 1: In this test, (a) A test was conducted and measured by changing the amount of ventilation in the ventilation layer in three ways. The results are shown in Figure 2. The ventilation amount of the (a) ventilation layer is 0.29.0.33.0.65X

In other words, the air flow is the smallest at 0.29X10-'cc

The skin temperature is controlled to a maximum temperature of approximately 42°C (characteristic i in Figure 2).

Also, the ventilation amount is 0.33.0.65X 10-'cc

Test 2: Here, an experiment was conducted by changing exothermic composition 4 from that in Test 1. The results are shown in FIG. 3 as characteristic iv.

However, by changing the exothermic composition, the maximum skin temperature can be controlled.

Test 3: Here, measurements were made by changing the temperature/humidity storage area from each of the above tests. Furthermore, the amount of ventilation in the ventilation layer was measured in two ways. The results are shown in Figure 4.

(a) 0.33.0.65 xio −'CC+ C

It can be seen that it remains almost constant and continues stably. From the comparison with the results of the above test, when the temperature and humidity distribution area changes,
The maximum temperature of the skin also changes, for example, as the temperature and humidity distribution area increases, the area of application to the human body increases, and as a result, the movement of red blood cells in the blood vessels of the human body becomes active and blood flow is promoted.
It is thought that skin temperature increases.

Test 4: Here, the hot compress was applied to the feet (shins) and measured. The results are shown in FIG. 5 as characteristic v pieces.

In this test result, it is thought that by measuring at different attachment points, differences due to differences in blood flow will appear, resulting in slight changes in characteristics. Furthermore, in this experiment, the skin temperature was measured to be higher than when the patch was applied to the waist. However, individual differences may also occur.

Test 5: Here, it was determined whether the hot compress had an effect on the outside temperature. The measurement results are shown in Figure 6. In FIG. 6, the characteristic i: is the skin temperature, and the symbol - is the outside air (temperature in the sauna).

Changes in the outside air Compared to smoking, the skin temperature characteristic viii is hardly affected by the outside temperature. Since the exothermic composition mentioned above is in close contact with each other, there is no deviation of the exothermic composition, and since the exothermic composition is always stable in contact with oxygen, the exothermic composition continues to generate heat at a constant temperature. Seem. In addition, it is thought that there is also a factor due to sweating due to the homeothermic effect of the human body, that is, as the outside temperature rises and the body temperature becomes higher, it is thought that an attempt is made to lower the body temperature by sweating.

Test 6: Here, as a comparative experiment, the amount of ventilation in the ventilation layer was varied from 0°1 to 0.

Measurements were made using a warm compress outside the range of '-Torr-'. That is, the ventilation amount is 1. OXIO-'cc-cm-

As shown in characteristic ix, the maximum skin temperature of the '・Torr-' hot compress reached 48°C for about 9 minutes after application, and subsequent measurements were not possible. I wasn't confused. There may also be a risk of burns (see Figure 7).

On the other hand, ventilation ito,t x 10-'cc-cm-''
・5ec-'・Torr-' or less of a hot compress has a small calorific value, so it is difficult to show an effect as a hot compress.

From the above experiments, this is possible.

Since the maximum temperature of the skin can be controlled, the maximum temperature can be adjusted to 44
When controlled at ℃, it is considered to be suitable for treatment of skin cancer, etc.

Furthermore, when the temperature is controlled at 43±1°C, it is thought to be effective in treating herpes and the like.

Furthermore, if the temperature is controlled at 38 to 42°C, it is thought to be effective in treating neuralgia, chronic rheumatism, lower back pain, and the like.

From the above, the specified ventilation N001~0.8X10-
The duration of the hot compress can be adjusted by changing the exothermic composition or the weight of the exothermic composition, as long as it is within the range of 4 cc cm-'' and 5 ec-1 Torr-'. By using a heat-generating composition suitable for the amount of ventilation, or by changing the structure of the hot compress, the above-mentioned maximum skin temperature of 38 to 46° C. can be satisfied.

In addition, with conventional disposable body warmers, there is no function that allows the heat-generating composition storage bag and the heat-generating composition to come into close contact with each other, so the amount of oxygen that comes into contact with the heat-generating composition constantly changes, resulting in unstable temperature characteristics. However, according to the present invention, this problem has been solved by using a microporous sheet with a predetermined amount of ventilation, and stable temperature characteristics can now be obtained. Furthermore, it is thought that because the poultice layer was in close contact with the skin, heat exchange between the skin and the heating element was almost unaffected by changes in outside temperature.

As a result, since the skin temperature and duration can be changed, it is not only effective in promoting local blood circulation and improving metabolic function, but it is also possible to provide a warm compress suitable for the patient. It is possible to create hot compresses suitable for various diseases.
