Description

  The present invention relates to a thermotherapy device using a chemical warmer used for thermotherapy of joints.

  Chemical warmers that use the heat of oxidation of metals such as iron, so-called disposable warmers, have been developed mainly for the purpose of easily obtaining heating. Various types are put on the market and have been proposed depending on the application site, such as a type to be applied to clothes and skin, a type to be laid on the sole, a type to be applied to the back of the foot (sock), a type to be wound in the form of a belt.

  Thus, the conventional chemical body warmers are assumed to be used in a stationary state, and therefore the conventional form is not suitable for heating the knee or elbow, wrist, or ankle, which are movable parts (joint parts). In particular, it is difficult to fix to knees and elbows with a large movable range.

  Recently, a type in which a chemical warmer itself is wound in a band shape has been proposed (Patent Document 1). However, in this case, the fixing device itself is a heating device, which covers a wide area other than a specific affected part, and becomes too hot, and can be used only in limited seasons and places. Further, although it is effective to some extent for rotational movements of the wrist, ankle, neck, etc., further improvement is required in that it cannot follow the large bending and expansion / contraction movements of the elbows and knees and is displaced.

  In addition, as described above, since the conventional chemical warmers are intended for heating, they have aimed at long-term heat generation at a relatively high temperature with a view to preventing low-temperature burns.

  Therefore, when diverting conventional chemical warmers to thermotherapy, which mainly involves treatment at relatively low temperatures, the temperature may exceed the temperature required for the intended treatment, and the risk of low-temperature burns due to easy diversion There are concerns. Although there have been proposals so far (Patent Document 2), further research is required for practical use.

  A first invention of the present invention comprises a cylindrical holder made of a stretchable material and a chemical warmer held by the holder, and the holder has a storage part in which the chemical warmer can be taken in and out. In addition, the present invention relates to a thermal treatment device that is attached to a knee or an elbow so that the chemical body storage part is positioned around a leg or an arm.

  A preferred embodiment of the thermal treatment device for elbows of the first invention will be described with reference to FIGS. 1 to 5, but the present invention is not limited to this embodiment, and various modifications can be made. Of course, it can also be implemented by changing the dimensions and the like as a thermal therapy device for the knee.

  1 is a schematic side view of a thermal treatment device for elbows according to the present invention, FIG. 2 is a sectional view taken along the line CC in FIG. 1, FIG. 3 is a sectional view taken along the line DD in FIG. FIG. 5 is a schematic explanatory view when the thermal treatment device of FIG. 1 is attached to the elbow.

  The thermotherapy device includes a cylindrical holder 1 and a chemical warmer 2, and the holder 1 is provided with a bag-shaped storage portion 3 in which the chemical warmer 2 can be taken in and out. In the present embodiment, the chemical warmer storage unit 3 is provided with two openings 5 for taking in and out the chemical warmer 2, and the chemical warmer 2 stored in the storage unit 3 is stored in the storage unit 3. It can be positioned freely.

  The holder 1 is made of a stretchable material so that it can follow the bending and stretching of the elbow joint. Further, if necessary, a tightening region 4 for facilitating fixing of the holder 1 may be provided in a part of the holder 1 (see FIG. 1).

  As described above, the holder 1 may stop blood flow when tightening too tight an arm, and may cause congestion. Therefore, the holder 1 is attached to the knee or elbow while the chemical body 2 is stored in the storage unit 3. It is preferable to set the pressure of 1 to the skin to 80 hPa or less. When congestion occurs, heat may accumulate in the affected area and low-temperature burns may occur. Therefore, it is desirable that the compression force be 40 hPa or less, particularly 35 hPa or less. Further, the lower limit is 10 hPa, further 20 hPa, especially 30 hPa, because if it becomes loose, the followability to the affected area is lost and it becomes easy to move and it is difficult to position the treatment site.

  In this embodiment, the holder 1 has a shape in which one stretchable fiber product (woven fabric, knitted fabric, nonwoven fabric, etc.) is folded and doubled to close the open portion, that is, a multi-structure bag. The opening 5 is opened during the knitting process. Although the opening 5 may be two places like this embodiment, it is 1-6 places according to the range and position to treat, and preferably 1-3 places. The arrangement of the opening 5 is not particularly limited.

  As shown in FIG. 4, the opening 5 is knitted with the outer cloth 6 of the bag-shaped holder 1 partially opened. In this case, the storage unit 3 is a space between the outer cloth 6 and the inner cloth 7 constituting the holder 1, and the chemical warmer 2 is stored therein.

  Although not shown, the bag-like holder 1 may be appropriately sewn to provide individual storage portions (pockets). In this case, if the pocket is arranged in the direction of bending of the joint, there is a feeling of pressure when the joint is bent. Therefore, the pocket is preferably provided on the side of the arm (a leg in the case of a knee) that does not hinder the movement of the joint. . However, depending on the treatment site, it may be arranged so as to surround the arm and / or vertically.

  Although not shown, the storage portion may be separately manufactured and sewn or pasted on the holder 1. When affixing, an adhesive may be used, or the position may be removably changed with a hook-and-loop fastener or the like.

  Moreover, a lid or a cover may be attached to the opening 5, and a button or a fastener (linear or hook-and-loop fastener) may be attached from the viewpoint of preventing the dropout.

The holder 1 is made of a stretchable material, but it is made of synthetic fibers alone, and also natural fibers such as plant fibers, animal fibers, and mineral fibers. May be selected as appropriate in consideration of properties, wear resistance, chemical resistance, and the like. Preferred examples of the fiber material include polyamide, polyurethane, and polyester. Moreover, although not limited, the thickness of a fiber may be 3-100 micrometers, Preferably it may be 10-50 micrometers. The mechanical properties of the fibers, 10~300kg / mm ² in tensile strength, preferably 10~100kg / mm ^2, 1~50% elongation, preferably 5-30%.

  Stretchability is also related to the material of the fiber, but can be controlled by the fabric production method. A knitted fabric is preferable, and a circular knitted fabric, a horizontal knitted fabric, a flat knitted fabric, a rubber knitted fabric, a pearl knitted fabric, a double-sided knitted fabric and the like are particularly preferable because a fabric knitted with a circular knitted fabric can be formed into a cylindrical shape without sewing.

  The holder 1 is manufactured with this stretchable material, but the fabrication method is not limited to the one sheet or bag shape as described above, but any method that does not impair the stretchability and flexibility. May be.

  What is necessary is just to enable the dimension of the holder 1 to select the thing of various sizes suitably according to the to-be-treated person's physique.

  Next, the chemical warmer which is the other component of the present invention will be described with reference to FIG.

  In the chemical warmer 2 used in the present invention, for example, as shown in FIG. 6, a heat generating composition 12 that generates heat in the presence of air is enclosed in a flat bag (hereinafter referred to as an inner bag) 11. The flat bag 11 is accommodated in an airtight bag (hereinafter referred to as an outer bag) 13.

  The exothermic composition 12 is preferably dispersed in the inner bag 11 at a basis weight of 0.1 to 1 g per 10 mm square in order to achieve uniform and gentle heat generation.

  The outer bag 13 is preferably made of a non-porous film such as polyethylene, polypropylene, silica-deposited film, and vinylidene chloride coated film. Among these, a vinylidene chloride coated film is preferable from the viewpoint of impermeability of oxygen and water vapor and appropriate permeability of hydrogen. The thickness of the nonporous film is preferably 30 to 300 μm.

  A conventional exothermic composition may be used as the exothermic composition 12 enclosed in the flat bag 11 and oxidatively generates heat in the presence of air. For example, metal powder such as iron powder, activated carbon, water, water retention agent (wood powder, vermiculite, diatomaceous earth, perlite, silica gel, alumina, water absorbent resin, etc.), salt, etc. can be used. It is not limited.

  The inner bag 11 is at least partly breathable and has vent holes or groups of micro holes. That is, one of the surfaces (the lower surface in FIG. 6) may be the air permeable surface 14 and the other surface may be the non-air permeable surface 15, or both surfaces may be air permeable surfaces. Furthermore, a part of one side may be a breathable surface and the rest may be a non-breathable surface.

  When a non-venting surface is provided, a synthetic resin such as nylon, polyethylene, or polypropylene is preferably used as the resin constituting the non-venting surface.

  The breathable surface is formed of a conventionally used material such as a woven fabric, a nonwoven fabric, a knitted fabric, a film perforated in the non-breathable material, or a combination thereof.

  The size of the inner bag 11 is not particularly limited in the present invention, and may be appropriately selected according to the shape, size, etc. of the chemical warmer storage (or pocket). In addition, the shape is not limited to a rectangle, and other shapes such as a circle, an ellipse, a tongue piece shape, and a heart shape can also be adopted. The thickness is 1 to 15 mm, preferably 2 to 8 mm from the viewpoint that the feeling of wearing is good and the movement of the joint is not easily hindered. Further, regarding the thickness, in addition to the uniform thickness, it is also possible to change the feeling of pressure by adding unevenness to the thickness of the inner bag 11.

  The air permeability of the inner bag 11 may be determined in consideration of the skin surface temperature and time at which a so-called low temperature burn can occur. For example, the skin temperature and time that may cause low temperature burns are 6 hours at a skin temperature of 42 ° C, 3 hours at 43 ° C, 1.5 hours at 44 ° C, and 45 minutes at 45 ° C. It may be controlled in consideration of the composition of the exothermic composition so as not to exceed the threshold value. However, if the treatment is performed for a short time, the heat may be generated at a higher temperature (for example, 60 ° C. or 70 ° C.).

Although not limited, the air permeability of the entire inner bag 11 is preferably 100 to 2000 g / m ² · 24 h in terms of water vapor permeability measured by A method (humidity sensor method) defined in JIS K7129. 200 to 800 g / m ² · 24 h is more preferable. If the water vapor permeability is greater than 2000 g / m ² · 24 h, the exothermic composition may generate excessive heat, and if it is less than 100 g / m ² · 24 h, the exothermic composition may not generate sufficient heat.

  The heating temperature and duration can also be controlled by the structure of the chemical body warmer 2 and the storage unit 3, particularly the inner (arm or knee side) cloth 7 or the outer cloth 6 of the storage unit 3.

For example, there are the following combinations, but the present invention is not limited to these.
(1) When the inner fabric has a breathable structure and the chemical warmer has a double-sided breathability In this case, a relatively high heat generation temperature can be obtained, but attention should be paid to low-temperature burns and the like.
(2) When the inner cloth has a breathable structure and the chemical warmer is breathable only on one side In this case, put the chemical warmer into the storage part 3 so that the ventilated surface of the chemical warmer is on the opposite side (outside) of the body Then, the intake of air becomes easy, and the heat generation temperature becomes relatively high (about 38 to about 42 ° C.). Conversely, when the chemical warmer is placed in the storage unit 3 so that the ventilation surface of the chemical warmer is on the body side (inside), the intake of air is restricted and the heat generation temperature becomes relatively low (about 36 to about 40 ° C.).

That is, it can be adjusted to the temperature required for the thermotherapy depending on the direction in which the chemical warmer 2 is inserted.
(3) When the inner fabric has a non-breathable or non-breathable structure and the chemical warmer is double-sided breathable In this case, a relatively high heat generation temperature can be obtained. It can be controlled by selectively setting the thermal conductivity.
(4) When the inner cloth has a non-breathable or hardly breathable structure and the chemical warmer is breathable only on one side. In this case, the chemical warmer as described in (2) above is taken into consideration, taking into account the thermal conductivity of the inner cloth. Depending on the direction in which 2 is inserted, the temperature can be adjusted to a temperature required for the thermal treatment.
(5) When both the inner cloth and the outer cloth are impermeable, and a means for putting in and out the chemical warmer is provided in the storage section In this case, the temperature adjustment necessary for the thermal treatment can be performed by the function of the storage section.

  In order to make the inner cloth non-breathable or non-breathable, for example, a non-breathable film may be attached to the body side of the storage portion.

  Moreover, the storage part of a chemical warmer can be made into the form which only locks (attaches) a chemical warmer instead of the bag shape (or pocket) as mentioned above. In this case, the chemical warmer is mounted on the outer surface or inner surface of the holder. Examples of means for attaching the chemical warmer include sticking with an adhesive, fixing with a hook-and-loop fastener, fixing with a button, and the like.

  When the chemical warmer is attached to the holder, an adhesive layer made of a normal adhesive substance is formed on one surface of the inner bag 11 (for example, the surface 14 in FIG. 6), and the adhesive layer is peeled off. Paper or a release film may be provided.

  The pressure-sensitive adhesive layer may be provided on one entire surface of the inner bag 11 or may be partially provided so as to form an appropriate pattern such as a striped pattern, a lattice pattern, or a polka dot pattern. Moreover, you may provide in a non-breathable surface and may provide in a breathable surface.

  The thermotherapy device of the type used for the elbow has been described above, but when used for the knee, the size may be adjusted according to the knee.

  Next, the second invention will be specifically described.

  The thermal therapy device for wrists of the second invention comprises a cylindrical holder made of a stretchable material and a chemical warmer held by the holder, and the holder comprises the wrist region, the palm and the back region of the hand. It has a storage part in which a chemical body warmer can be put in and out or attached to the wrist region, and has an opening through which the finger of the hand is inserted in the palm and back of the hand region.

  A preferred embodiment of the wrist thermal therapy device of the present invention will be described with reference to FIGS. 8 to 11. However, the present invention is not limited to this embodiment, and various modifications are possible. Of course, it can also be implemented as a thermal treatment device for an ankle by making the following modifications.

  FIG. 8 is a schematic perspective view of the thermal treatment device for wrist according to the present invention, FIG. 9 is a schematic explanatory view when the thermal treatment device of FIG. 8 is attached to the wrist, and FIG. 10 is a diagram of another embodiment. FIG. 11 is a schematic perspective view, and FIG. 11 is a cross-sectional view taken along line AA of FIG.

  The thermal treatment device includes a cylindrical holder 101 and a chemical warmer 102, and the holder 101 includes a wrist region 103 and a palm and a back region (hereinafter referred to as a “back region”) 104.

  The wrist region 103 of the holder 101 is provided with a bag-shaped storage portion 105 in which the chemical warmer 102 can be taken in and out. In this embodiment, the chemical warmer storage unit 105 is provided with one opening 106 for taking in and out the chemical warmer 102, and the chemical warmer 102 stored in the storage unit 105 is stored in the storage unit 105. It can be positioned freely.

  The back region 104 of the hand of the holder 101 has insertion openings 107 and 108 through which fingers of the hand are inserted. The insertion opening 107 is an opening for inserting the thumb of the left hand when the wrist of the left hand is subjected to heat treatment (see FIG. 9), and the insertion opening 108 is an opening for inserting the thumb of the right hand when applied to the right hand. In addition, the finger to insert is not specifically limited, Therefore, the position and number of the insertion openings 107 and 108 are also not limited.

  The holder 101 is made of a stretchable material and can follow the bending and stretching of the wrist joint. In the second invention, a tightening region 109 is provided in the wrist region of the holder 101 for facilitating fixing of the holder 101 (see FIG. 8). The storage portion 105 of the chemical warmer 102 is preferably formed in the tightening region 109. However, as shown in FIG. 10, the tightening region may be a ring-shaped region 109 a, and one to several, for example, one to three may be provided to narrow the region actually used for tightening.

  As described above, when the wrist is tightened too tightly, the holder 101 may stop blood flow and cause congestion. Therefore, the holder 101 is attached to the wrist or ankle while the chemical warmer 102 is stored in the storage unit 105. It is preferable to set the pressing force of 101 to the skin to 80 hPa or less. When congestion occurs, heat may accumulate in the affected area and low-temperature burns may occur. Therefore, it is desirable that the compression force be 40 hPa or less, particularly 35 hPa or less. Further, the lower limit is 10 hPa, further 20 hPa, especially 30 hPa, because if it becomes loose, the followability to the affected area is lost and it becomes easy to move and it is difficult to position the treatment site.

  In this embodiment, the holder 101 has a shape in which one stretchable fiber product (woven fabric, knitted fabric, non-woven fabric, etc.) is folded and doubled to close the open portion, that is, a multi-structure bag. And the opening part 106 is provided at the time of a knitting process. Although the opening part 106 may be one place like this embodiment, 1-6 places, Preferably 1-3 places are arrange | positioned according to the range and position to treat. The arrangement of the opening 106 is not particularly limited.

  As shown in FIG. 11, the opening 106 is knitted with the outer cloth 110a of the bag-like holder 101 partially opened. In this case, the storage unit 105 is a space between the outer cloth 110a and the inner cloth 110b constituting the holder 101, and the chemical warmer 102 is stored therein.

  Although not shown, the bag-like holder 101 may be appropriately sewn to provide individual storage portions (pockets). In this case, if the pocket is placed in the direction of bending of the joint, there is a feeling of pressure when the joint is bent, so the pocket does not obstruct the movement of the joint (the back side of the hand) (for the ankle, the back side of the foot) Is preferred. However, depending on the treatment site, it may be arranged so as to surround the wrist and / or in a vertical direction.

  Although not shown, the storage portion may be separately manufactured and sewn or pasted on the holder 101. When affixing, an adhesive may be used, or the position may be removably changed with a hook-and-loop fastener or the like.

  Moreover, a lid or a cover may be attached to the opening 106, or a button or a fastener (linear or hook-and-loop fastener) may be attached from the viewpoint of preventing the opening from being dropped.

The holder 101 is made of a stretchable material, but as a material, synthetic fibers alone, and natural fibers such as plant fibers, animal fibers, and mineral fibers are mixed to create stretchability, wearing feeling, thermal conductivity, and processing. May be selected as appropriate in consideration of properties, wear resistance, chemical resistance, and the like. Preferred examples of the fiber material include polyamide, polyurethane, and polyester. Moreover, although not limited, the thickness of a fiber may be 3-100 micrometers, Preferably it may be 10-50 micrometers. The mechanical properties of the fibers, 10~300kg / mm ² in tensile strength, preferably 10~100kg / mm ^2, 1~50% elongation, preferably 5-30%.

  Stretchability is also related to the material of the fiber, but can be controlled by the fabric production method. A knitted fabric is preferable, and a circular knitted fabric, a horizontal knitted fabric, a flat knitted fabric, a rubber knitted fabric, a pearl knitted fabric, a double-sided knitted fabric and the like are particularly preferable because a fabric knitted with a circular knitted fabric can be formed into a cylindrical shape without sewing.

  The holder 101 is made of this stretchable material, but any method can be used as long as it is a method that does not impair stretchability and flexibility, as well as a single piece or a bag-like shape as described above. May be.

  What is necessary is just to enable it to select suitably the dimension of the holder 101 of various sizes according to the to-be-treated person's physique.

  Next, the chemical warmer as the other component of the present invention will be described with reference to FIG.

  In the chemical warmer 102 used in the present invention, for example, as shown in FIG. 12, an exothermic composition 112 that generates oxidation heat in the presence of air is enclosed in a flat bag (hereinafter referred to as an inner bag) 111, The flat bag 111 is accommodated in an airtight bag (hereinafter referred to as an outer bag) 113.

  The exothermic composition 112 is preferably dispersed in the inner bag 11 at a basis weight of 0.1 to 1 g per 10 mm square in order to achieve uniform and gentle heat generation.

  The outer bag 113 is preferably made of a non-porous film such as polyethylene, polypropylene, a silica deposited film, and a vinylidene chloride coated film. Among these, a vinylidene chloride coated film is preferable from the viewpoint of impermeability of oxygen and water vapor and appropriate permeability of hydrogen. The thickness of the nonporous film is preferably 30 to 300 μm.

  A conventional exothermic composition may be used as the exothermic composition 112 that is enclosed in the flat bag 111 and oxidatively generates heat in the presence of air. For example, metal powder such as iron powder, activated carbon, water, water retention agent (wood powder, vermiculite, diatomaceous earth, perlite, silica gel, alumina, water absorbent resin, etc.), salt, etc. can be used. It is not limited.

  The inner bag 111 is at least partly air permeable and has vent holes or groups of micro holes. That is, one surface 114 may be a breathable surface and the other surface 115 may be a non-breathable surface, or both surfaces may be breathable surfaces. Furthermore, a part of one side may be a breathable surface and the rest may be a non-breathable surface.

  When a non-venting surface is provided, a synthetic resin such as nylon, polyethylene, or polypropylene is preferably used as the resin constituting the non-venting surface.

  The breathable surface is formed of a conventionally used material such as a woven fabric, a nonwoven fabric, a knitted fabric, a film perforated in the non-breathable material, or a combination thereof.

  The size of the inner bag 111 is not particularly limited in the present invention, and may be appropriately selected according to the shape and size of the chemical warmer storage (or pocket). In addition, the shape is not limited to a rectangle, and other shapes such as a circle, an ellipse, a tongue piece shape, and a heart shape can also be adopted. The thickness is 1 to 15 mm, preferably 2 to 8 mm from the viewpoint that the feeling of wearing is good and the movement of the joint is not easily hindered. Further, regarding the thickness, in addition to the uniform thickness, it is possible to change the feeling of pressure by making the thickness of the inner bag 111 uneven.

  The air permeability of the inner bag 111 may be determined in consideration of the skin surface temperature and time at which a so-called low temperature burn can occur. For example, the skin temperature and time that may cause low temperature burns are 6 hours at a skin temperature of 42 ° C, 3 hours at 43 ° C, 1.5 hours at 44 ° C, and 45 minutes at 45 ° C. It may be controlled in consideration of the composition of the exothermic composition so as not to exceed the threshold value. However, if the treatment is performed for a short time, the heat may be generated at a higher temperature (for example, 60 ° C. or 70 ° C.).

Although it is not limited, the air permeability of the entire inner bag 111 is preferably 100 to 2000 g / m ² · 24 h in terms of water vapor permeability measured by A method (humidity sensor method) defined in JIS K7129. 200 to 800 g / m ² · 24 h is more preferable. If the water vapor permeability is greater than 2000 g / m ² · 24 h, the exothermic composition may generate excessive heat, and if it is less than 100 g / m ² · 24 h, the exothermic composition may not generate sufficient heat.

  The heat generation temperature and duration can also be controlled by the structure of the chemical warmer 102 and the storage part 105, particularly the inner cloth 110b and the outer cloth 110a of the storage part 105.

For example, there are the following combinations, but the present invention is not limited to these.
(1) When the inner fabric has a breathable structure and the chemical warmer has a double-sided breathability In this case, a relatively high heat generation temperature can be obtained, but attention should be paid to low-temperature burns and the like.
(2) When the inner cloth has a breathable structure and the chemical warmer is breathable only on one side In this case, put the chemical warmer into the storage part 5 so that the ventilated surface of the chemical warmer is on the opposite side (outside) of the body Then, the intake of air becomes easy, and the heat generation temperature becomes relatively high (about 38 to about 42 ° C.). On the other hand, when the chemical warmer is placed in the storage part 5 so that the ventilation surface of the chemical warmer is on the body side (inside), the intake of air is restricted and the heat generation temperature becomes relatively low (about 36 to about 40 ° C.).

That is, it can be adjusted to the temperature required for the thermotherapy depending on the direction in which the chemical warmer 102 is inserted.
(3) When the inner fabric has a non-breathable or non-breathable structure and the chemical warmer is double-sided breathable In this case, a relatively high heat generation temperature can be obtained. It can be controlled by selectively setting the thermal conductivity.
(4) When the inner cloth has a non-breathable or hardly breathable structure and the chemical warmer is breathable only on one side. In this case, the chemical warmer as described in (2) above is taken into consideration, taking into account the thermal conductivity of the inner cloth.
