DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compress which can be used for a hot compress and a method for producing the same.

[0002]

2. Description of the Related Art When bruising somewhere in the body, when the throat is upset by a cold, or when a built-in disease such as heartburn or stomachache occurs, a towel moistened with hot water is applied to the affected area for treatment. Has been used for a long time in medical institutions and general households as a simple treatment using a "hot compress".

[0003]

However, the treatment with the conventional hot compress is performed when the towel is squeezed with hot water,
Burns may occur when a towel moistened with hot water is applied to the affected area, or the towel applied to the affected area may cool down in a short period of time, preventing the effective warm compress effect from being maintained. Since the towels moistened in a short time cool down in a short time, the work of squeezing the towels in hot water has to be repeated many times in a short time.

[0004] By the way, the inventor of the present application went to an outdoor athletic after the rain, and fell down by sliding his feet from a height of several meters. At this time, the neck bone abnormality managed to return to its original condition at the medical institution, but since then the dull pain did not go away and he had a hard time every day. I was trying to find a cure for myself that I couldn't find, but when I was preparing for a meal one day, the following things came to my attention.

[0005] That is, when warming an article using a microwave oven, it has been noticed that the contents of a wrapped food packaging wrapped film become hot and the warmth lasts for a long time. Therefore, paying attention to this point, wet a water-retaining base such as a towel or a towel with water, wrap the wet base with multiple layers of food wrap film, warm it with a microwave oven, and then apply it to the affected area. An attempt was made to cure by applying a hot compress. The inventors found that there is little risk of burns and that the effect of the hot compress lasts for a long time, thereby completing the present invention.

The present invention has been made under the above circumstances, and has a low risk of burns and the like, and has excellent handleability.
Moreover, an object of the present invention is to provide a poultice that can be used many times.

It is another object of the present invention to provide a poultice having a poultice effect that lasts for a long time.

Another object of the present invention is to provide a method for easily and inexpensively producing the above-mentioned compress.

[0009]

The poultry device according to the present invention comprises:
A flat base material that can be heated and is moistened with water having water retention is covered with a coating material having no water permeability in a degassed state.

[0010] This poultice is heated by a heating device such as a microwave oven and then applied to an affected part of the body to exhibit a hot compress effect. In addition, when the operation of reheating when the heated substrate is cooled is repeated, it is possible to repeatedly use the heating pad for the heating compress. In particular, in this compress, the coating material does not have water permeability. For this reason, the water-moist substrate covered with the coating material may dry out early, or the steam generated by heating the water-moist substrate may escape through the coating material. Things don't happen. In addition, since the substrate has a water retention property, the substrate always holds a sufficient amount of moisture, and moreover, it is unlikely that water drops will flow out of the substrate. When these properties are synergistic, according to the poultice of the present invention, there is little danger of burns, the handleability is excellent, and a predetermined hot compress effect can be obtained even when used repeatedly.

It is desirable that the covering material is formed by overlapping synthetic resin films. A food packaging wrap film can be suitably used as the synthetic resin film.

[0012] When the wound material is wrapped only once around a body moistened with water and applied to the affected part of the body, the heat of the heated body is almost directly transmitted to the affected part through the covering material, and depending on the temperature of the body, a burn may be caused. It cannot be said that there is no risk. However, as described above, when the covering material is formed by overlapping the synthetic resin films, even when the substrate wet with water is at a high temperature, the affected area hit by the poultice tool is not covered with the covering material. , It can be gently warmed to an appropriate temperature, and in addition, the temperature of the substrate is less likely to decrease. Therefore, the effect of the hot compress is maintained for a long time, and the situation in which the substrate is cooled early does not occur. An ultra-thin polyvinylidene chloride resin film is known as a food packaging wrap film that can be used for a synthetic resin film. The effect of preventing heat dissipation and the effect of calming the way heat is transmitted from the substrate to the affected part are remarkably exhibited, and the above-mentioned gentle warm compress effect is maintained for a long time. In addition, since the polyvinylidene chloride resin film hardly changes its properties even when placed in a heating mode microwave oven, the initial hot compress effect is unlikely to decrease even if the compress is repeatedly used.

The above compress can be easily and inexpensively manufactured by the method described below. That is,
After moistening the base with water retention that is folded flat,
An operation of winding a long covering material having no water permeability onto the base material and winding the covering material several times and folding both ends in the width direction of the covering material wound around the base material on the base material is performed. Thus, the substrate can be easily and inexpensively manufactured by coating the substrate in a degassed state.

The poultice thus prepared can be used as a hot compress for an affected area by placing it in a microwave oven and heating it for a required time. As described above, a food packaging wrap film can be suitably used for the covering material.

[0015]

FIG. 1 is a sectional view of a compress according to the present invention. In this poultice, a flat base 1 moistened with water that can be heated and has water retention is covered in a degassed state by a coating material 2 having no water permeability.

The base 1 can be made of a cloth having excellent water retention such as "towel" or "towel". These materials not only have excellent water retention properties, but also have the advantage of being flexible and easily adaptable to the affected part of the body. Base 1 with "towel"
When using towels or towels, it is desirable to fold the base 1 into a flat rectangle, and if so,
The substrate 1 has an appropriate thickness, and its flexibility can be sufficiently exhibited, and at the same time, the water retention is enhanced.

As the coating material 2, a very thin wrap film for food packaging made of a synthetic resin film, particularly a polyvinylidene chloride resin film can be suitably used. When a food packaging wrap film is used as the covering material 2, it is desirable that the wrap film be wound around the substrate 1 in a multi-layered manner. In addition, due to the structural properties of the overlapping food wrap film,
Does not escape to the outside of the coating material 2. At the same time, the heated heat of the base 1 is transmitted to the affected part through the superposed covering material 2, so that the affected part can be gently warmed to an appropriate temperature, and in addition, the temperature of the base 1 is hard to decrease. Become. In the compress described with reference to FIG. 1, the base 1 is moistened with water, and if the base is heated in a microwave oven (a cooking device using microwaves), the temperature of the base 1 rises. Therefore, if the patient is taken out of the microwave oven after the heating and applied to the affected part of the body, the affected part is subjected to hot compress. In addition, when the operation of reheating when the heated substrate is cooled is repeated, it is possible to repeatedly use the heating pad for the heating compress.

Next, a specific method of using the above compress is illustrated below.

When the compress is heated in a microwave oven, the coating material 2 swells due to the moisture evaporated from the material 1 during the heating. May be adjusted, and the heating time is usually set to 1 to 2 minutes. After the microwave oven is turned off, wait until the covering material 2 is removed. The waiting time at this time is about 10 to 20 seconds. When the swelling of the coating material 2 has been removed, the compress is removed from the microwave oven. This eliminates the risk of burns.

Since the compress taken out of the microwave oven is relatively hot, it is put into a resin sheet or resin film bag and its mouth is firmly held in order to make it easier to hold by hand and to enhance the heat retaining effect. It is desirable to keep it closed. As the bag, for example, a shopping bag for putting a product when shopping at a supermarket or the like can be preferably used, and by doing so, the shopping bag can be effectively used.

Depending on the temperature of the compress, it is possible to apply the compress in the bag as it is to the affected part of the body as it is to perform hot compressing. However, it is usually too hot to apply the compress directly to the affected part. Wrap the packed compress with a dry towel and apply it to the affected area. In this case, it is necessary to fix the poultice to the affected part so that it does not shift, using a large cloth, for example, a furoshiki wrapped around the poultice, wrapping the furoshiki around the body and applying the temperature of the poultice to the affected part. It is good to tell.

In this way, the warm compress effect of the compress applied to the affected area before going to bed may be continued until the user awakes in the morning of the next day, and the symptoms of the affected area may be suppressed by the long-time warm compress effect. Help. When the compress is repeatedly used, when the temperature has dropped to around the body temperature, the above operation may be repeated by heating again with the microwave oven.

FIGS. 2 to 7 show a method of manufacturing the above-mentioned compress, which will be described below.

FIG. 2 shows a state in which a horizontally long towel employed as the base 1 is folded in eight. This foundation 1
Is a flat square, and is rich in flexibility and water retention.
After the substrate 1 folded as shown in FIG. 2 is sufficiently immersed in water, the substrate is loosely squeezed to remove excess water. The squeezing method at this time should be slightly looser than when squeezing the "towel". In such a case, the base 1 may be moistened with a necessary and sufficient amount of water, and the water may flow out of the base 1. Nothing happens. If the squeezing method is too gentle, a large amount of steam may be generated at the time of heating, and a coating material described later may be peeled off.

Next, as shown in FIG. 3, on a horizontally long covering material 2a employing a very thin and transparent food wrap film,
The substrate 1 is placed in a landscape orientation. Then, the covering material 2a is brought into close contact with the substrate 1 and wound about 10 times, and then pressed down from above to keep the shape flat, and the air in the overlapping portion of the substrate 1 and the covering material 2a is expelled and deaerated. After deaeration, as shown in FIG. 4, both ends 22, 22 in the width direction of the coating material 2a are folded on the overlapping coating material 2a. Thereafter, if necessary, further degassing is performed, and the both ends 22, 22 are pressed to be brought into close contact with the coating material 2a. If degassing is not necessary, both ends 22, 22 are immediately pressed to make close contact with the covering material 2a.

Next, as shown in FIG. 5, the intermediate A of FIG. 4 is replaced with a horizontally long covering material 2b employing an ultra-thin and transparent food packaging wrap film (the same covering material 2a as described above can be used). This time, put it vertically long, and put the covering material 2 in the same manner as above.
After b is wound about 10 times, it is pressed down from above to keep the shape flat and degassed. After the degassing, as shown in FIGS. 6 and 7, both ends 23 in the width direction of the coating material 2b are folded on the overlapping coating material 2b. Thereafter, if necessary, further deaeration is performed, and both ends 23, 23 are pressed to cover material 2
b. If no degassing is required, immediately 2 ends
3 and 23 are pressed against and brought into close contact with the coating material 2b.

The compressing pad C of FIGS. 6 and 7 thus obtained.
Can be used for hot compress treatment after heating according to the procedure already described.

Next, the results of a questionnaire on the effect of the hot compress treatment according to the procedure described above using the compress C prepared by the above method will be described.

FIG. 8 shows the results of counting questionnaires on a predetermined number of patients. In the figure, A is "very good", B is "good", C is "no change",
D represents each of those who answered "worse".

According to the tabulated results in FIG. 8, no one has worsened. From this, it can be said that there is almost no possibility that the poultry pad has any adverse effect on the medical conditions shown in FIG. Also, stiff shoulders, back pain, knee pain, sore throat due to cold,
For tired kidneys, chills, etc.
The total number of those who answered "very good" or "good" exceeded 10 people. From this, it can be said that the above-mentioned poultice is extremely effective in suppressing these various symptoms. Other symptoms are "very good"
Or, many respondents answered "I'm better", and none said "No change" or only about one person. It is very effective for

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a compress which can be used for a hot compress.

[0002]

2. Description of the Related Art When bruising somewhere in the body, when the throat is upset by a cold, or when a built-in disease such as heartburn or stomachache occurs, a towel moistened with hot water is applied to the affected area for treatment. Has been used for a long time in medical institutions and general households as a simple treatment using a "hot compress".

[0003]

However, the treatment with the conventional hot compress is performed when the towel is squeezed with hot water,
Burns may occur when a towel moistened with hot water is applied to the affected area, or the towel applied to the affected area may cool down in a short period of time, preventing the effective warm compress effect from being maintained. Since the towels moistened in a short time cool down in a short time, the work of squeezing the towels in hot water has to be repeated many times in a short time.

[0004] By the way, the inventor of the present application went to an outdoor athletic after the rain, and fell down by sliding his feet from a height of several meters. At this time, the abnormalities in the neck bones managed to return to their original condition at the medical institution, but even after that, the dull pain did not disappear and he spent a difficult day. I was trying to find a cure for myself that I couldn't find, but when I was preparing for a meal one day, the following things came to my attention.

[0005] That is, when warming an article using a microwave oven, it has been noticed that the contents of a wrapped food packaging wrapped film become hot and the warmth lasts for a long time. Therefore, paying attention to this point, wet a water-retaining base such as a towel or a towel with water, wrap the wet base with multiple layers of food wrap film, warm it with a microwave oven, and then apply it to the affected area. An attempt was made to cure by applying a hot compress. The inventors found that there is little risk of burns and that the effect of the hot compress lasts for a long time, thereby completing the present invention.

The present invention has been made under the above circumstances, and has a low risk of burns and the like, and has excellent handleability.
In addition, it is an object of the present invention to provide a method for easily and inexpensively producing a compress that can be used repeatedly many times.

[0007]

The method of manufacturing a compress according to the present invention can be easily and inexpensively manufactured by the method described below. That is, after the flat-folded water-retentive substrate is moistened with water, the substrate is placed horizontally on a horizontally-long, non-permeable, horizontal covering material, and the covering material is brought into close contact with the substrate. After wrapping over the turns, press down further from above to keep the shape flat, expel air from the superposed part of the base material and coating material and deaerate, and after deaeration, overlap the both ends in the width direction of the coating material By folding on the covering material, an intermediate body formed by covering the substrate in a degassed state with the covering material is formed. Next, the intermediate body is placed on a horizontally long covering material having no water permeability. After placing the coating material vertically on the intermediate body, winding it several times around the intermediate body, holding it from above, keeping it flat, degassing together, and after degassing, both ends in the width direction of the coating material, Easy and inexpensive method by folding over the covering material and making it adhere to the covering material It is possible to produce.

[0008] The poultice thus prepared can be used as a hot compress for an affected part by placing it in a microwave oven and heating it for a required time. In addition, a food packaging wrap film can be suitably used as the covering material.

The poultice produced by this method is heated by a heating device such as a microwave oven and then applied to an affected part of the body to exhibit a hot compress effect. In addition, when the operation of reheating when the heated substrate is cooled is repeated, it is possible to repeatedly use the heating pad for the heating compress. In particular, in this compress, the coating material does not have water permeability. For this reason, the situation where the water-moist substrate covered with the coating material dries early,
The situation in which the steam generated by heating the substrate moistened with water escapes through the coating material does not occur. Moreover, since the base has water retention, the base always holds a sufficient amount of moisture, and
It is also unlikely that water drops will flow out of the substrate. When these properties are synergistic, according to the poultice made by the method of the present invention, there is little danger of burns, the handleability is excellent, and a predetermined hot compress effect can be obtained even when used repeatedly.

By the way, when a coating material is wrapped around a body moistened with water only once and applied to the affected part of the body, the heat of the heated base material is transmitted to the affected part through the covering material as it is, and depending on the temperature of the base material. It cannot be said that there is no risk of burns. However, as described above, when the covering material is formed by overlapping the synthetic resin films, even when the substrate wet with water is at a high temperature, the affected area hit by the poultice tool is not covered with the covering material. , It can be gently warmed to an appropriate temperature, and in addition, the temperature of the substrate is less likely to decrease. Therefore, the effect of the hot compress is maintained for a long time, and the situation in which the substrate is cooled early does not occur. As a food packaging wrap film that can be used for a synthetic resin film, an ultra-thin polyvinylidene chloride resin film is known, and when this polyvinylidene chloride resin film is superimposed and covered with a wet base material,
The effect of preventing the escape of water and the effect of calming the way of heat transfer from the substrate to the affected area will be remarkably exhibited,
The gentle warm compress effect as described above is maintained for a long time. In addition, since the polyvinylidene chloride resin film hardly changes its properties even when it is put in a microwave oven in a heating mode, the initial hot compress effect is hardly reduced even if the compress is repeatedly used.

[0011]

FIG. 1 is a sectional view of a poultice made by the method of the present invention. In this poultice, a flat base 1 moistened with water that can be heated and has water retention is covered in a degassed state by a coating material 2 having no water permeability.

For the substrate 1, a cloth having excellent water retention such as "towel" and "towel" can be used. These materials not only have excellent water retention properties, but also have the advantage of being flexible and easily adaptable to the affected part of the body. Base 1 with "towel"
When using towels or towels, it is desirable to fold the base 1 into a flat rectangle, and if so,
The substrate 1 has an appropriate thickness, and its flexibility can be sufficiently exhibited, and at the same time, the water retention is enhanced.

As the coating material 2, a very thin food packaging wrap film made of a synthetic resin film, in particular, a polyvinylidene chloride resin film can be suitably used. When a food packaging wrap film is used as the covering material 2, it is desirable that the wrap film be wound around the substrate 1 in a multi-layered manner. In addition, the base material 1
Does not escape to the outside of the coating material 2. At the same time, the heated heat of the base 1 is transmitted to the affected part through the superposed covering material 2, so that the affected part can be gently warmed to an appropriate temperature, and in addition, the temperature of the base 1 is hard to decrease. Become. In the compress described with reference to FIG. 1, the base 1 is moistened with water, and if the base is heated in a microwave oven (a cooking device using microwaves), the temperature of the base 1 rises. Therefore, if the patient is taken out of the microwave oven after the heating and applied to the affected part of the body, the affected part is subjected to hot compress. In addition, when the operation of reheating when the heated substrate is cooled is repeated, it is possible to repeatedly use the heating pad for the heating compress.

Next, a specific method of using the above compress is illustrated below.

When the compress is heated in a microwave oven, the coating material 2 swells due to the moisture evaporated from the material 1 during the heating.
The heating time may be adjusted with reference to the start of the swelling of the coating material 2 as a guide, and usually the heating time may be set to 1 to 2 minutes. After the microwave oven is turned off, wait until the covering material 2 is removed. The waiting time at this time is 10-2
It is about 0 seconds. When the swelling of the coating material 2 is removed, the compress is removed from the microwave oven. This eliminates the risk of burns.

Since the compress is removed from the microwave oven at a relatively high temperature, it is put into a resin sheet or a resin film bag and its mouth is firmly held in order to make it easy to hold by hand and to enhance the heat retaining effect. It is desirable to keep it closed. For this bag, for example, a shopping bag for putting in a product when shopping at a supermarket or the like can be preferably used, and by doing so, the shopping bag can be effectively used.

Depending on the temperature of the compress, it is possible to apply the compress in the bag as it is to the affected part of the body as it is to perform hot compressing. However, it is usually too hot to apply the compress directly to the affected part. Wrap the packed compress with a dry towel and apply it to the affected area. In this case, it is necessary to fix the poultice to the affected part so that it does not shift, using a large cloth, for example, a furoshiki wrapped around the poultice, wrapping the furoshiki around the body and applying the temperature of the poultice to the affected part. It is good to tell.

[0018] In this way, the warm compress effect of the compress applied to the affected area before going to bed may be sustained until awakening in the morning of the next day, and the symptoms of the affected area may be suppressed by the long-time warm compress effect. Help. When the compress is repeatedly used, when the temperature has dropped to around the body temperature, the above operation may be repeated by heating again with the microwave oven.

FIGS. 2 to 7 show a method of manufacturing the above-mentioned compress, which will be described below.

FIG. 2 shows a state in which a horizontally long towel employed as the base 1 is folded in eight. This foundation 1
Is a flat square, and is rich in flexibility and water retention.
After the substrate 1 folded as shown in FIG. 2 is sufficiently immersed in water, the substrate is loosely squeezed to remove excess water. The squeezing method at this time should be slightly looser than when squeezing the "towel". In such a case, the base 1 may be moistened with a necessary and sufficient amount of water, and the water may flow out of the base 1. Nothing happens. If the squeezing method is too gentle, a large amount of steam may be generated at the time of heating, and a coating material described later may be peeled off.

Next, as shown in FIG. 3, on a horizontally long covering material 2a employing a very thin and transparent food packaging wrap film,
The substrate 1 is placed in a landscape orientation. Then, the covering material 2a is brought into close contact with the substrate 1 and wound about 10 times, and then pressed down from above to keep the shape flat, and the air in the overlapping portion of the substrate 1 and the covering material 2a is expelled and deaerated. After deaeration, as shown in FIG. 4, both ends 22, 22 in the width direction of the coating material 2a are folded on the overlapping coating material 2a. Thereafter, if necessary, further degassing is performed, and the both ends 22, 22 are pressed to be brought into close contact with the coating material 2a. If degassing is not necessary, both ends 22, 22 are immediately pressed to make close contact with the covering material 2a.

Next, as shown in FIG. 5, the intermediate A in FIG. 4 is replaced with a horizontally long covering material 2b employing an ultra-thin and transparent food wrap film (the same as the above-mentioned covering material 2a can be used). This time, put it vertically long, and put the covering material 2 in the same manner as above.
After b is wound about 10 times, it is pressed down from above to keep the shape flat and degassed. After the degassing, as shown in FIGS. 6 and 7, both ends 23 in the width direction of the coating material 2b are folded on the overlapping coating material 2b. Thereafter, if necessary, further deaeration is performed, and both ends 23, 23 are pressed to cover material 2
b. If no degassing is required, immediately 2 ends
3 and 23 are pressed against and brought into close contact with the coating material 2b.

The compressing pad C of FIGS. 6 and 7 thus obtained.
Can be used for hot compress treatment after heating according to the procedure already described.

Next, the results of a questionnaire on the effect of the hot compress treatment according to the procedure described above using the compress C prepared by the above method will be described.

FIG. 8 shows the results of the questionnaire for a predetermined number of patients. In the figure, A is "very good", B is "good", C is "no change",
D represents each of those who answered "worse".

According to the tabulated result of FIG. 8, no one has become worse, and it can be said that there is almost no possibility that the above-mentioned poultry equipment has an adverse effect on the medical conditions shown in FIG. Also, stiff shoulders, back pain, knee pain, sore throat due to cold,
For tired kidneys, chills, etc.
The total number of those who answered "very good" or "good" exceeded 10 people. From this, it can be said that the above-mentioned poultice is extremely effective in suppressing these various symptoms. Other symptoms are "very good"
Or, many respondents answered "I'm better", and none said "No change" or only about one person. It is very effective for
