[Brief explanation of the drawings]

[0012] [Figure 1] 1 is an explanatory diagram showing a heating appliance according to a first embodiment of the present invention. [Figure 2] 10 is a modified example of the shape of the first cylindrical portion. DETAILED DESCRIPTION OF THE INVENTION

[0013] First Embodiment FIG. 1 is an explanatory diagram showing a heating tool 1 according to a first embodiment of the present invention.

[0014] 1(a) is a cross-sectional view taken along line AA in FIG. 1(b), and FIG. 1(b) is a cross-sectional view taken along line BB in FIG. 1(a). The heating device 1 is used by inserting it from the top as shown in Figure 1(b) into the nasal cavity, ear canal, urethra, navel hole, oral cavity, vagina, or rectum. The following description will first focus on the inside of the vagina or rectum, but as will be described later, the same applies to other openings, although the size may differ. The heating device 1 generates heat, and therefore can warm the body from the inside. This promotes blood circulation and can improve various physical symptoms. Symptoms that may be improved include, for example, the following: These benefits include reducing menstrual pain, promoting blood circulation (improving sensitivity to cold), improving urinary incontinence, improving vaginal dryness, improving odor, improving tightness, and promoting pregnancy.

[0015] The heating device 1 has a structure as shown in FIG. Specifically, it has a rod-like cylindrical structure with a dome-shaped tip. This dome shape (smoothly chamfered) reduces the impact when inserted into the body. The heating appliance 1 has at least a main body portion 31 . The main body 31 has a dome-shaped main body leading end 32, a cylindrical first columnar portion 33, and a second columnar portion 34 having a larger diameter than the first columnar portion. Furthermore, since the first cylindrical portion 33 and the second cylindrical portion are coaxially adjacent to each other, a step portion 35 is formed. The first cylindrical portion 33 preferably has a length two to three times longer than the second cylindrical portion , and in some cases even longer.

[0016] The heat generating portion 21 is disposed so as to cover the outside (outer periphery, front portion) of the first cylindrical portion 33 and the front portion 32 of the main body portion. The heat generating unit 21 may be similar to a (disposable) body warmer (of course, the shape and the shape and material of the nonwoven fabric of the iron powder container may be changed). More specifically, it may be anything that generates heat by reacting with air (oxidation reaction) (for example, but not limited to, the oxidation reaction of iron powder). As shown in Figure 1, the shape of the heat generating part 21 is composed of a cylindrical heat generating part cylindrical part 23 that covers the first cylindrical part 33, and a hollow dome-shaped heat generating part front part 22 that covers the main body part front part 32. However, the heat generating part 21 may be simply cylindrical without the dome-shaped part (heat generating part cylindrical part 23). In this case, it is possible to use a commercially available disposable body warmer as it is. However, it goes without saying that the heating part 21 made for the heating device 1 is better than a commercially available disposable hand warmer. Furthermore, the cylindrical shape is not limited to an original cylindrical shape, and may be formed by wrapping a plate-like material such as a normal disposable body warmer around the cylindrical shape. It is of course best to have this heat generating part 21 custom-made. The term "disposable warmer" does not mean that a commercially available disposable warmer can be used as is, but rather that it can be easily manufactured with current technology if made from the same materials, and is merely an example that makes it easy to understand the present invention (it is much more appropriate to make the shape to suit the present invention). However, it goes without saying that the materials can of course be changed. The nonwoven fabric can also be made from other materials (plastic film, paper, etc.).

[0017] The protective portion 11 is provided to cover the heat generating portion 21. The protective part 11 may be, for example, a commercially available condom. Of course, it goes without saying that the protective part 11 made for the heating device 1 is better than commercially available condoms. In this case, the protective part 11 may be made of polyurethane or silicone material. In this case, it is possible to adjust the thickness, material, etc. for temperature control, etc. This makes it possible to make the embodiment more preferable. The protective portion 11 has a thin cylindrical protective portion 13 and a hollow dome-shaped protective portion front portion 12.

[0018] This protective part 11 is generally almost airtight. Therefore, in order to supply air to the heat generating section 21 that generates heat using air, the main body section 31 needs to allow air to pass through. As a result, the main body 31 must be made of a material or have a shape that allows air to pass through. Examples include a three-dimensional network fiber structure, a three-dimensional fine fiber structure, and BreathAir (registered trademark). In order to adjust the heat generation amount of the heat generating portion 21 and the flexibility of the heating device itself, the density of the fibers in the three-dimensional network fiber structure may be adjusted. Additionally, in order to adjust the amount of heat generated, an adjustment section that adjusts the amount of air passing through may be disposed, for example, between the second cylindrical section 34 and the first cylindrical section 33. This adjustment section may be, for example, in the shape of a disk with through holes, and the amount of heat generated may be adjusted by adjusting the size and number of the through holes.

[0019] As an example of specific dimensions, the following dimensions are preferable as an example. The length of the first cylindrical portion 33 is preferably about 70 to 100 mm. The length of the second cylindrical portion 34 is preferably about 15 to 40 mm. The diameter of the first columnar portion 33 covered with the heat generating cylindrical portion 23 and the protective cylindrical portion 13 is preferably about 10 to 30 mm. It is desirable that the diameter of the second cylindrical portion 34 is the same as that of the first cylindrical portion 33 .

[0020] <Changes in the shape of the main body> 10 shows a modified example of the shape of the first cylindrical portion 33.

[0021] As shown in FIG. 1, the first cylindrical portion 33 and the second cylindrical portion 34 of the main body are different in size, but they may also be the same size. Furthermore, the second cylindrical portion 34 may have a smaller diameter than the first cylindrical portion 33. Furthermore, the step 35 between the first cylindrical portion 33 and the second cylindrical portion 34 does not need to be stepped, but may change smoothly. Furthermore, the cross section of the first cylindrical portion 33 (second cylindrical portion 34) does not have to be circular, and may be elliptical, oval, or polygonal with hexagons or more. Furthermore, as shown in FIG. 2, it may be circular, elliptical, or oval in shape. In addition, as shown in FIG. 2, a certain obtuse angle portion 33a may be provided in a circular, elliptical, or oval shape. This is because doing so may reduce the burden on the vagina or rectum. Also, the obtuse angle portion 33a makes it possible to define the direction.

[0022] <Second embodiment> In the second embodiment, the shape of the main body 31 of the present invention can be manufactured not only in a relatively large shape such as a vagina or a rectum, but also in a smaller shape. Various manufacturing methods are possible, including the use of a 3D printer, injection molding, or a three-dimensional network fiber structure, among other methods. Moreover, it is also possible to easily manufacture the heat generating portion 21 accordingly. If it is made small, it can be inserted into any opening in the human body other than the vagina or rectum. For example, it can be inserted into the nasal cavity, ear canal, urethra, umbilical hole, etc. By warming these points, various symptoms such as internal inflammation and discomfort can be alleviated, improved, and people can become healthier. For example, when inserted into the nasal cavity, it can alleviate and improve various diseases and symptoms such as sinusitis, hay fever, and headaches. Furthermore, when inserted into the ear canal, it is expected to alleviate symptoms such as otitis media and headaches. It can also be used to treat other symptoms such as nasal cavity, ear canal, eye strain, stiff shoulders, temporomandibular joint disorder, and all other symptoms that can generally be alleviated, improved, and made healthier by applying heat (same below). The urethra can be used if it is made thinner, which can be used to treat cystitis, various sexually transmitted diseases, and urethral discomfort. In the case of an umbilical hole, the length will be shorter and thicker, but it is still possible to use it. In this case, we believe it would be better to have tape to prevent it from falling off. <Third embodiment> Furthermore, devices that are inserted into the oral cavity are also possible. In such cases, it is desirable for the device to be shaped like a hemisphere so that it fits snugly into the oral cavity. Although measures against saliva, etc. are necessary, it can be used. In this case, you can expect various effects, such as improvement of oral hygiene, relief of stomatitis, relief of periodontal disease, relief of toothache, etc. In this case, you can also expect effects on headaches, stiff shoulders, temporomandibular joint disorder, etc. <Fourth embodiment> In the case of the nasal cavity, it is appropriate that the heat generating portion 21 is only on the outer periphery of the cylinder, because it is the nose, and it is better to allow air to pass through. Furthermore, it is preferable that the main body 31 be rod-shaped with a smoothly chamfered tip, but since it is not inserted by pushing it open like the vagina or rectum, there is little necessity for the tip to be rod-shaped with a smoothly chamfered tip. This is also true for the ear canal (to allow sound to pass through). However, since the ear canal is much more curved than the nasal cavity, it would be more appropriate for the external part 31 to be rod-shaped with a smoothly chamfered tip. <Fifth embodiment> The protective part 11 is not necessarily required. The role of the protective equipment 11 is to prevent pain or injury due to contact with the tissue inside the user's hole, but it is not necessarily necessary if the surface of the heat generating part 21 is made of a material or has a shape that is gentler on the human body or if it does not rub against the tissue inside the user's hole. In addition, the role of the protective equipment 11 is to prevent excessive heat generation caused by air being supplied to the heat generating part 21 from the outside (the main body part 31 supplies air from the inside), and to adjust the heat generation by the amount of air passing through the main body part 31. However, if the shape of the main body 31 is appropriately designed (manufactured), the amount of heat generated can be appropriately adjusted even if air is supplied from the outside. Therefore, the protective equipment 11 is not necessarily required. In particular, in the case of the nasal cavity, ear canal, and navel hole, there is little possibility of rubbing, so it is likely that it is not necessary in many cases. Furthermore, in particular for nasal cavities, ear canals, and umbilical holes, commercially available condoms cannot be used due to size and other restrictions, so there is a good chance that you will not use them. Sixth Embodiment The shape of the heating appliance 1 including the main body 31 does not necessarily have to be straight, and may be warped or bent as necessary. For example, in the case of the nasal cavity, ear canal, etc., a certain degree of curvature may be allowed for deep insertion. Furthermore, the mask may have irregularities to provide a better fit, to provide a feeling of fit, to prevent it from falling off, and to reduce discomfort. Furthermore, the tip may be tapered or, conversely, may be thicker toward the tip, as required.Furthermore, the thickness may vary depending on the position in a more complex manner. For example, the part that needs to be heated more may be made thicker to improve heat transfer. Seventh Embodiment It is better for the heating device 1, including the main body 31, to have a certain degree of elasticity (to bend, dent, or deform) in order to provide a comfortable fit, reduce pain when inserted, and prevent injury when moving or when force is applied from another source. Eighth Embodiment The three-dimensional reticular fiber structure may be, for example, a three-dimensional mesh structure or a three-dimensional Voronoi structure. In other words, any structure is acceptable as long as it is possible to form a body portion with a certain shape and allow air to pass through (as long as the amount of air can be adjusted). <Ninth embodiment> The main body 31 can also be formed, for example, in a test tube shape by forming holes, slits, etc. The amount of heat generated can be adjusted by changing the shape, number, size, position, etc. of the holes and slits. <Tenth embodiment> In the above, it was assumed that the heat generation method was a scientific method (chemical reaction). However, the essence of this invention is to alleviate, improve and improve symptoms by applying heat inside various points. Therefore, it is not necessarily limited to the scientific method (generating heat through a chemical reaction in the bag). For example, a method of generating heat using power from a battery (which of course includes reusable batteries) may be used. However, even in this case, it is appropriate that the cord does not extend from the main body 31. In other words, it is appropriate that the battery is housed inside the main body 31.

[0023] <Configuration and Effects of the Embodiment> The heating device 1 of this embodiment has a rod-shaped main body 31, and a heating section 21 that can be placed over at least the tip and outer periphery of the main body 31 and is formed so as to be detachable from the main body 31. The main body 31 has an air gap structure that allows air to pass freely through, and is formed so that air is supplied to the heating section 21 from the base side of the main body 31 (for example, the second cylindrical section 34). With this configuration, it is possible to provide a heating element for the nasal cavity, ear canal, urethra, navel hole, oral cavity, vagina or rectum that can effectively warm a specific area by warming the body from inside the nasal cavity, ear canal, urethra, navel hole, oral cavity, vagina or rectum.

[0024] The tip of the main body 31 is smoothly chamfered. This configuration reduces the discomfort felt when inserting the device and prevents damage to the tissue around the inner periphery of the hole.

[0025] The heat generating portion is formed so as to cover the tip side as well. With this configuration, the body tissue at the tip side can also be heated. Conversely, if this portion is not covered, it is possible to allow air (including sound) to pass through more easily. In that case, the protector 11 is absent or formed so that air (sound) can pass through.

[0026] The heat generating portion 21 is a heat generating element that generates heat by reacting with air. With this configuration, it is possible to generate heat remotely with an extremely simple configuration and without the need for electrical equipment.

[0027] The main body 31 has a cross section formed in a circular or elliptical shape. This configuration can reduce discomfort in the vagina or rectum.

[0028] The main body 31 is formed of a three-dimensional reticular fiber structure, a three-dimensional net structure, or a three-dimensional Voronoi structure. With this configuration, air can be supplied to the heat generating portion 21 with a simple structure.

[0029] The structure, materials, connections of the components, chemical substances, and the like of the present invention can be variously changed without departing from the spirit of the present invention. The material can be freely selected from plastic, metal, foam material, etc. For example, it is possible to combine two or more components into one, or conversely, it is possible to configure one component from two or more separate components and connect them together. Furthermore, the above embodiment is merely one of the best modes currently available. [Explanation of symbols]
