Description

Technical Field

[0001] The present invention relates to a radon inhalation device which enables a user to efficiently inhale radon and enables the user to obtain the same effect as hot spring therapy in a radon hot spring. Background Art

[0002] In Japan, Misasa Onsen and Tamagawa Onsen, which are famous for their radon hot springs, are well known for their therapeutic effects on various diseases. In addition, in Austria and Germany, radon inhalation therapy is recognized as a medical practice for neuralgia, peripheral circulatory disorders, etc. Therefore, various devices focusing on the effectiveness of hot springs containing radioactive decay products such as radon have been proposed.

[0003] For example, a radon inhaler known in the past is configured to accommodate a plurality of ores containing radioactive substances in a bottomed cylindrical container, the open end of the container is sealed by a lid, external air is introduced into the container from an air supply pipe installed in the lid, and a user is configured to inhale radon released from the ores containing radioactive substances in the container through an air intake pipe installed in the lid (see Patent Document 1).

[0004] Patent Document 1: Japanese Patent Application Publication No. 2007-313274

[0005] When such a conventional radon inhaler is used in an environment where the ambient air temperature is low, there is a problem that the user cannot inhale radon of a desired concentration (a concentration at which the same therapeutic effect as that of a radon hot spring can be expected). Summary of the invention

[0006] Therefore, an object of the present invention is to provide a radon inhalation device that allows a user to always inhale a stable concentration of radon without being affected by the surrounding atmospheric temperature and allows the user to obtain the same effect as hot spring therapy in a radon hot spring.

[0007] The radon inhalation device according to the present invention comprises: a radon generating container for generating radon; and a heating unit for heating the interior of the radon generating container.

[0008] The radon generating container comprises: a container body, the interior of which is divided into a radon storage chamber and an external air open chamber by a bag; an ore containing a radioactive substance, which is contained in the radon storage chamber; and a radon decoupling body, which connects the interior of the radon storage chamber with the exterior of the container body.

[0009] The radon decompression body is configured such that if the bag is deformed in a manner to increase the volume of the radon storage chamber, external air can be introduced into the radon storage chamber, and if the gas in the internal space is sucked from the outside of the container body, the radon in the radon storage chamber is released to the outside of the container body.

[0010] According to the present invention, the radon generating container can be heated to a temperature suitable for radon generation by a heating unit, so that the user can always inhale a stable concentration of radon without being affected by the surrounding atmospheric temperature, and the user can obtain the same effect as hot spring therapy with radon hot springs.

Figure 1 As shown, the radon inhalation device 1 according to the present embodiment can be stored and carried in a state of being accommodated in the box 2, and can be used in a state of removing the top plate 2a of the box 2. In addition, the radon inhalation device 1 according to the present embodiment can be used, stored, and carried in a state of being taken out of the box 2. In addition, the box 2 is mainly formed of wood, but is not limited to this, and plastics and metals can be used appropriately.

[0050] Figures 2A to 2D 1 is a diagram showing a radon inhalation device 1 according to a first embodiment of the present invention. Figure 2A 1 is a top view of the radon inhalation device 1. Figure 2B1 is a front view of the radon inhalation device 1. Figure 2C This is a right side view showing a portion of the container body 4 of the radon inhalation device 1 cut away. Figure 2D yes Figure 2C A partial enlarged view of the radon inhalation device 1 is shown.

[0051] like Figure 2A , Figure 2B As shown, the radon inhalation device 1 comprises: a radon generating container 5 for generating radon; and a heating unit 6 for heating the interior of the radon generating container 5. The radon generating container 5 comprises: a container body 4 for accommodating a radioactive material-containing ore 7 (e.g., dry radium ore) and a heating unit 6; a bag 11 for dividing the interior of the container body 4 into a radon storage chamber 8 and an external air open chamber 10; a bag fixing member 13 detachably mounted on an opening 12 of the container body 4; a radon decompression body 14 for connecting the radon storage chamber 8 with the exterior of the container body 4; a gas flow path 15 mounted on the radon decompression body 14; and a valve 16 for opening and closing the gas flow path 15.

[0052] The container body 4 has: a cubic bottomed cylindrical portion 17; and a cylindrical opening portion 12 integrally formed in the bottomed cylindrical portion 17. In addition, a bottom peripheral groove 18 is formed along the outer peripheral edge at the bottom portion of the bottomed cylindrical portion 17. A bag fixing member 13 for fixing the opening end 11a of the bag 11 is detachably mounted on the opening portion 12. The bag fixing member 13 has an inner fixing body 20 and an outer fixing body 21. The inner fixing body 20 hooks the flange portion 20a on the front end surface of the opening portion 12 of the container body 4, and detachably fits the outer peripheral surface 20b on the inner peripheral surface of the opening portion 12 of the container body 4. The inner fixing body 20 clamps the opening end 11a side of the bag 11 between the inner fixing body 20 and the front end surface and inner peripheral surface of the opening portion 12, thereby fixing the opening end 11a side of the bag 11 to the opening portion 12. The outer fixing body 21 has an internal thread formed on the inner circumferential surface screwed into an external thread formed on the outer circumferential surface of the opening 12, so that the flange portion 20a of the inner fixing body 20 and the opening end 11a side of the bag 11 are clamped by the flange portion 21a to the front end surface of the opening 12, and the inner fixing body 20 and the opening end 11a side of the bag 11 are fixed to the container body 4. In addition, the inner fixing body 20 and the outer fixing body 21 of the bag fixing member 13 are configured so that the operation hole 22 of the same diameter opens concentrically with the opening 12 of the container body 4.

[0053] In addition, if Figure 2AAs shown, a sheet-shaped heating portion (planar heater) 6 is housed inside the container body 4 in a manner spanning the adjacent side walls of the container body 4. The heating portion 6 is flexibly deformable, inserted into the inside of the container body 4 from the opening 12 of the container body 4, and is arranged so that the center portion is located at the corner where the radon deductor 14 is arranged. In addition, the heating portion 6 is connected to an external power source via a power cable 23, and is energized by turning on a power switch 24, thereby generating heat and heating the inside of the container body 4. In addition, the heating portion 6 is not limited to a heating portion (planar heater) 6 housed inside the container body 4 as in the present embodiment, and can be a heater arranged outside the radon generating container 5 as long as it can heat the inside of the radon generating container 5.

[0054] In addition, if Figure 2C As shown, the bag 11 is formed of a thin film of synthetic resin or rubber in a manner that allows for easy deformation, and has a bottomed cylindrical shape with an open end 11a. The bag 11 is fixed to the opening 12 of the container body 4 with the open end 11a opened, thereby separating the interior of the container body 4 into a radon storage chamber 8 and an external air open chamber 10. That is, in Figure 2C , Figure 2D In the embodiment, the bag 11 fixed to the opening 12 of the container body 4 forms a radon storage chamber 8 between the outer surface and the inner surface of the container body 4, and forms an external air open chamber 10 on the inner surface side. In addition, the bag 11 is more preferably transparent so that other storage objects (such as the heating unit 6 and the radon derivation body 14) in the container body 4 can be observed from the operation hole 22 of the bag fixing part 13.

[0055] Figures 3A to 3D 1 is a diagram showing a radon guide body 14 constituting the radon inhalation device 1 according to the first embodiment of the present invention. Figure 3A 1 is a top view of the radon derivation body 14. Figure 3B This is a front view of the radon guide body 14. In addition, Figure 3C It is a right side view of the radon guide body 14. In addition, Figure 3D Yes Figure 3B This is an enlarged cross-sectional view of the radon derivation body 14 cut along line A1 - A1.

[0056] like Figures 2A to 2D and Figures 3A to 3DAs shown in FIG. 1 , the radon deriver 14 is arranged inside the container body 4 and provided with a corner 25 of the heating unit 6, and has a substantially right-angled isosceles triangle shape when viewed from above. The radon deriver 14 has flow paths 26 and 27 set up in parallel. That is, the flow paths 26 and 27 set up in parallel of the radon deriver 14 are composed of a central flow path 26 and a pair of side flow paths 27 and 27 located on both sides of the central flow path 26, respectively, and the lower part of the central flow path 26 and the lower part of the pair of side flow paths 27 and 27 are connected via a communication port 28. Moreover, the central flow path 26 is connected to the outside of the container body 4 via a gas flow path 15 installed in a gas flow path installation hole 31 formed in the top 30 of the radon deriver 14. In addition, the pair of side flow paths 27 and 27 are connected to the radon storage chamber 8 via a plurality of vents 32 and 33, respectively.

[0057] In addition, if Figures 3A to 3D As shown, the radon deriver 14 receives the liquid 34 at the lower part of the flow paths (central flow path 26 and a pair of side flow paths 27, 27) set in parallel, and normally (when there is no difference between the indoor pressure of the radon storage chamber 8 and the external pressure of the container body 4), the liquid level of the liquid 34 is located above the communication port 28, the liquid level of the central flow path 26 and the liquid level of the pair of side flow paths 27, 27 are at the same height, and the communication port 28 is blocked by the liquid 34 (refer to Figure 5A , Fig. 7A ). In addition, the radon guide body 14 contains filter gravel 35 at the lower part of the central flow path 26 (see Figures 5A-5B , Figures 7A-7B ). In addition, the liquid 34 contained in the radon deriver 14 may be water, but more preferably, the liquid 34 may be a colored liquid such as green tea which allows easy visual confirmation of the remaining amount of the liquid and has a bactericidal effect.

[0058] In addition, if Figure 3B , 3C As shown, the radon decompression body 14 has liquid splash prevention walls 36, 37 formed obliquely downward at the upper part of the central flow path 26 and the upper part of a pair of side flow paths 27, 27 to prevent liquid splashing, and a gap 40 for allowing gas to pass is formed between the front end of each liquid splash prevention wall 36, 37 and the flow path wall 38.

[0059] In addition, if Figure 3B , 3C As shown, the radon deductor 14 has a pair of supporting protrusions 41 , 41 formed on the lower surface side. The pair of supporting protrusions 41 , 41 engage with the bottom peripheral groove 18 of the container body 4 , so that the radon deductor 14 is held in a state of being positioned at the corner 25 in the container body 4 .

[0060] Figures 4A to 4E 1 is an exploded view of the radon guide 14. Figures 4A to 4EAs shown, the radon derivation body 14 comprises: a body portion 42; a substantially flat front wall portion 43, which blocks the front surface of the body portion 42; and a bottom cover member 44 having a bottomed cylindrical shape, which is fitted into the lower end side of the body portion 42 and the front wall portion 43. Such a radon extractor 14 is formed by engaging a pair of tongue-shaped first engaging protrusions 45 formed on the upper part of the front wall 43 with a pair of first mounting holes 46 formed on the upper part of the body 42, and engaging a plurality of second engaging protrusions 47 formed along the two side edges of the front wall 43 with a plurality of second mounting holes 48 (the same number as the second engaging protrusions 47) formed along the side edges of the body 42, so that the hook 50 of the second engaging protrusion 47 is hooked on the opening edge 51 of the second mounting hole 48, and the body 42 and the front wall 43 are detachably (separably) integrated by the elastic force of the second engaging protrusion 47. At this time, for the radon deriver 14, the end surface of the flow path wall 38 that separates the central flow path 26 and the side flow path 27 of the body 42 abuts against the inner surface of the front wall 43, and the central flow path 26 and the side flow path 27 are separated by the flow path wall 38 and the front wall 43. In addition, for the radon deriver 14, after the body 42 and the front wall 43 are assembled and before the bottom cover member 44 is assembled to the body 42 and the front wall 43, the pair of flow path walls 38, 38 protrude (expose) downward than the body 42 and the front wall 43.

[0061] In addition, if Figures 4A to 4E As shown, the radon decompression element 14 is formed by fitting the open end 52 side of the bottom cover member 44 into the thin-walled portions 53, 54 at the lower end sides of the body portion 42 and the front wall portion 43, and the lower end sides of the body portion 42 and the front wall portion 43 are blocked by the bottom cover member 44. In addition, in the radon decompression element 14, the end surfaces of the portions of the pair of flow path walls 38, 38 that protrude downward from the body portion 42 and the front wall portion 43 abut against the inner surface of the bottom cover member 44, and the exchange of gas between the central flow path 26 and the side flow path 27 is suppressed except for the communication port 28.

[0062] like Figures 2A to 2CAs shown, the gas flow path 15 includes: an L-shaped curved pipe 56, which is installed through a sleeve 55, and the sleeve 55 is hooked and set on both the gas flow path installation hole 31 formed on the top 30 of the radon derivation body 14, and a through hole (not shown) formed at a position matching the gas flow path installation hole 31 on the upper wall portion 64 of the container body 4; an elastically deformable tube 57 connected to the curved pipe 56; and a suction nozzle member 58 detachably fitted to the front end of the tube 57. In addition, for the gas flow path 15, a simple valve 16 for opening and closing the flow path is installed on the front end side of the tube 57, and the flow of gas in the flow path (tube 57) is stopped by closing the valve 16, and the flow of gas in the flow path (tube 57) is allowed by opening the valve 16. The sleeve 55 is installed at the corner portion of the upper wall portion 64 of the container body 4, so that the periphery of the gas flow path mounting hole 31 of the radon decomposing body 14 is tightly attached to the periphery of the through hole of the container body 4, and the gap between the bent pipe 56 and the container body 4 is sealed to prevent the gas in the container body 4 from leaking to the outside of the container body 4.

[0063] Figure 5A , 5B : is a diagram showing a first usage state of the radon inhalation device 1 according to the present embodiment. Figure 5A 1 is a diagram showing the state of use of the radon inhalation device 1 before radon extraction. Figure 5B It is a figure which shows the usage state of the radon inhalation device 1 at the time of radon suction.

[0064] like Figures 2A to 2D and Figure 5A As shown, in the radon inhalation device 1, the container body 4 is heated by the heating unit 6, and a part of the liquid 34 in the radon deriver 14 becomes water vapor to increase the humidity in the radon storage chamber 8, and the radon released from the ore containing radioactive substances 7 is stored in the radon storage chamber 8. Then, the radon inhalation device 1 is as shown in FIG. Figures 2A to 2D and Figure 5BAs shown, if the gas in the inner space 39 of the central flow path 26 in the radon decommissioning body 14 is sucked by the user through the gas flow path 15, the liquid level of the central flow path 26 rises, and the liquid levels of the pair of side flow paths 27, 27 fall. The liquid levels of the pair of side flow paths 27, 27 slightly fall from the upper edge of the communication port 28. If a small gap is generated between the liquid levels of the pair of side flow paths 27, 27 and the upper edge of the communication port 28, a portion where the pressure drops sharply is generated between the liquid 34 lifted up in the central flow path 26 and the liquid 34 remaining on the bottom side of the radon decommissioning body 14, and the surrounding gas flows into the portion where the pressure drops sharply, and the gas flows in sharply in the form of being blown into the liquid 34 of the central flow path 26. As a result, in the radon inhalation device 1, the gas containing radon passes through the liquid 34 in the central flow path 26 of the radon decommissioning body 14 in the form of bubbles, and flows out in the form of being broken on the upper surface of the liquid 34 in the central flow path 26. At this time, the liquid splashed on the liquid surface hits the liquid splash prevention wall 36 of the central flow path 26 and falls, so it does not flow into the gas flow path 15. In addition, in the radon inhalation device 1, the gas containing radon passes through the gap between the liquid splash prevention wall 36 and the flow path wall 38, and the gas containing radon is sucked by the user through the gas flow path 15. At this time, the particulate matter and other unwanted substances of the gas passing through the liquid 34 of the central flow path 26 are captured by the liquid 34.

[0065] Figure 6 1 is a diagram showing a second usage state of the radon inhalation device 1 according to the present embodiment, and is a diagram showing a portion of the container body 4 cut away. Figure 6 As shown, in the radon inhalation device 1, when the gas in the radon storage chamber 8 decreases and the volume of the radon storage chamber 8 divided by the bag 11 decreases (when the bag 11 is deformed as shown by the double-dashed line), if the user inserts his hand through the operation hole 22 of the bag fixing member 13 fixed to the opening 12 of the container body 4 (refer to Figures 2A to 2D ), and the user holds and lifts the operating portion 60 of the bag 11, the volume of the radon storage chamber 8 increases rapidly, and the pressure in the radon storage chamber 8 decreases rapidly. As a result, for the radon inhalation device 1, the liquid 34 in the side flow path 27 of the radon deductor 14 increases rapidly, and the liquid 34 in the central flow path 26 of the radon deductor 14 decreases rapidly (refer to Figure 7B ).

[0066] Fig. 7A , Figure 7B : is a diagram showing a third usage state of the radon inhalation device 1 according to the present embodiment. Fig. 7A 1 is a diagram showing the state of use of the radon inhalation device 1 before the introduction of external air. Figure 7B It is a figure which shows the usage state of the radon inhalation device 1 when introducing the outside air.

[0067] like Fig. 7A , 7B As shown, for the radon inhalation device 1, if the lower surface of the liquid 34 in the central flow path 26 of the radon decontamination body 14 moves to the upper edge of the communication port 28, a tiny gap is generated between the liquid 34 remaining on the bottom side of the radon decontamination body 14, and a sharp pressure drop occurs in the gap portion, and the gas in the central flow path 26 flows in through the communication port 28 in a manner of being blown into the liquid 34 in the side flow path 27. The gas that flows in by being blown into the side flow path 27 becomes bubbles and rises in the liquid 34 in the side flow path 27, and flows out in a manner of cracking on the upper surface of the liquid 34 in the side flow path 27. At this time, the liquid 34 splashed on the liquid surface collides with the liquid splash prevention wall 37 of the side flow path 27, preventing it from flowing out into the radon storage chamber 8 (refer to Figure 3B , 3C ). In addition, the radon inhalation device 1 is not limited to Figure 3B and Figure 7B In the embodiment shown, the vent 33 of the side flow path 27 may be omitted. Figure 3B and Figure 7B In the illustrated embodiment, it is preferable to provide the liquid splash prevention wall 37 at a position lower than the vent 33 located at the lowermost position of the side flow channel 27 .

[0068] Figure 8 This is a diagram showing a fourth usage state of the radon inhalation device 1 according to the present embodiment, and is a diagram showing a portion of the container body 4 cut away.

[0069] like Figure 8 As shown, in the radon inhalation device 1, when the operation of taking in external air to the radon storage chamber 8 is completed, the bag 11 is pressed near the opening 12 of the container body 4 in a manner of being flattened by the taken in external air, and most of the interior of the container body 4 becomes the radon storage chamber 8. In addition, in the radon inhalation device 1, when radon is accumulated in the radon storage chamber 8, the valve 16 of the gas flow path 15 is closed to cut off the flow of gas in the gas flow path 15 (see Figure 2A In addition, in order to prevent foreign matter from falling into the container body 4, it is preferable to engage the cover member 61 in a detachable state in the operation hole 22 of the inner fixing body 20 and the outer fixing body 21 of the bag fixing member 13 installed in the opening 12 of the container body 4 (see Figure 2D ).

[0070] exist Figure 8 In the state shown, for the radon inhalation device 1, if the interior of the container body 4 is heated by the heating unit 6, the vapor generated from the liquid 34 inside the radon decomposition body 14 flows into the radon storage chamber 8, and the temperature and humidity in the radon storage chamber 8 become appropriate, then radon is efficiently released from the radioactive substance-containing ore 7 into the radon storage chamber 8.

[0071] The radon inhalation device 1 involved in the present embodiment as described above can heat the radon generating container 5 to a temperature suitable for radon generation through the heating unit 6, so that the user can always inhale a stable concentration of radon without being affected by the surrounding atmospheric temperature, and the user can obtain the same effect as hot spring therapy of radon hot springs.

[0072] In addition, the radon inhalation device 1 according to this embodiment is Figure 5B and Figure 7B As shown, filter gravel 35 is accommodated in the lower part of the central flow path 26 of the radon deriver 14, so the filter gravel 35 can prevent the bubbles passing through the liquid in the central flow path 26 from becoming larger, and the liquid splashing can be prevented from occurring. In addition, for the radon inhalation device 1 involved in this embodiment, the material accommodated in the lower part of the central flow path 26 is not limited to the filter gravel 35, as long as the same effect as the filter gravel 35 can be expected, for example, it can also be a steel ball-shaped material.

[0073] In addition, the radon inhalation device 1 according to this embodiment is Figure 5B As shown, the gas that becomes bubbles and passes through the liquid in the central flow path 26 generates liquid splash when the liquid surface breaks, but the liquid splashed on the liquid surface collides with the liquid splash prevention wall 36, thereby preventing the liquid from flowing into the gas flow path 15.

[0074] Furthermore, in the radon inhalation device 1 according to the present embodiment, a mode in which a pair of side flow paths 27 and 27 are formed in the radon derivation body 14 is exemplified, but the present invention is not limited thereto, and one of the pair of side flow paths 27 and 27 may be omitted.

[0075] In the present embodiment, unnecessary substances such as particulate matter are captured by the liquid 34, so the need for providing a filter is low. However, in order to improve the effect of capturing unnecessary substances, a filter may be provided in the radon deductor 14 and the gas flow path 15 as needed.

[0076] (Variation 1 of the First Embodiment)

[0077] like Figure 2A As shown, for the radon inhalation device 1, an external air inlet 65 for communicating the inside of the radon storage chamber 8 with the outside of the container body 4 is formed on the upper wall portion 64 of the container body 4, which is positioned in a manner to surround the opening portion 12 of the container body 4. The external air inlet 65 is located at a corner of the upper wall portion 64 of the container body 4 that is opposite to the sleeve 55, is blocked by engaging a plug body 66 (such as a rubber plug, a plastic plug, etc.), and is opened by removing the plug body 66.

[0078] The radon inhalation device 1 according to this modification is as follows: Figure 6 and Figure 7B As shown, when introducing external air into the radon storage chamber 8 of the container body 4, the plug 66 is removed from the external air inlet 65 and the external air inlet 65 is opened. Compared with the case where the external air is introduced into the radon storage chamber 8 only through the gas flow path 15 and the radon lead-out body 14, the external air can be introduced into the radon storage chamber 8 from the gas flow path 15, the radon lead-out body 14 and the external air inlet 65, so the external air can be introduced into the radon storage chamber 8 easily and in a short time.

[0079] In addition, the radon inhalation device 1 according to the present modification can suppress the amount of external air introduced through the radon guide 14, thereby suppressing the splashing of the liquid at the liquid surface of the side flow path 27 (see Figure 7B ).

[0080] Furthermore, in the radon inhalation device 1 according to the present modification, after the outside air is introduced into the radon storage chamber 8 , the outside air introduction port 65 is closed with the plug 66 .

[0081] (Variation 2 of the first embodiment)

[0082] The radon inhalation device 1 according to the first embodiment directly covers the radon generating container 5 with the ore 7 containing radioactive substances. However, in order to increase the surface area of ​​the ore 7 containing radioactive substances and promote the efficient release of radon, it is preferred to powder the ore 7 containing radioactive substances. When the ore 7 containing radioactive substances is powdered, radon can be efficiently released into the radon storage chamber 8, but it is also easy to enter the radon derivation body 14. Fig. 9A , 9B As shown, it is preferable that the powdered radioactive material-containing ore 7 is placed in a bag 70 made of nonwoven fabric or the like and stored in the radon storage room 8 .

[0083] (Variation 3 of the first embodiment)

[0084] In the first embodiment, a valve 16 for opening and closing the gas flow path 15 is provided in the gas flow path 15 attached to the radon decomposing body 14, and a filter is provided in the radon decomposing body 14 and the gas flow path 15 as needed. However, when the gas containing radon is sucked from the radon decomposing body 62 through the gas flow path 15, the valve 16 and the filter easily become ventilation resistance. Therefore, for people with weak suction power, there is a concern that the gas containing radon cannot be sufficiently sucked.

[0085] Therefore, the radon deriver 14 and the gas flow path 15 connected thereto according to the first embodiment may not be provided with valves or filters, so that the ventilation resistance is minimized. Even if the valves or filters are discarded and the gas flow path 15 is opened, since the radon deriver 14 contains the liquid 34 inside, the flow path leading to the radon storage chamber 8 and the flow path leading to the gas flow path 15 are sealed by the liquid 34, so there is no problem that the gas containing radon leaks through the gas flow path 15.

[0086] (Variation 4 of the first embodiment)

[0087] Furthermore, in order to reduce the ventilation resistance of the gas containing radon, Fig.10 As shown, the radon extractor 14 may be discarded. Figure 5A , Figure 5B , Fig. 7A , Figure 7B Filter gravel 35 shown in FIG. When the filter gravel 35 is discarded, bubbles passing through the liquid become larger, and liquid splashing is likely to occur, but it becomes easy to suck gas containing radon together with water vapor, so radon is easily sucked deep into the human body.

[0088] (Variation 5 of the First Embodiment)

[0089] In addition, if Fig.11 As shown, a joint pipe 19 may be provided in the gas flow path 15 to replace the valve 16, and the suction nozzle component 58 may be detachably provided via the joint pipe 19. If it is assumed that the suction nozzle component 58 is frequently replaced, the replacement of the suction nozzle component 58 becomes easy by providing a joint pipe 19 that can be detachably connected to the suction nozzle component 58 at the front end of the gas flow path 15.

[0090] <Second embodiment>

[0091] Fig.12 FIG. 9 is a diagram showing a radon inhalation device 1 according to a second embodiment of the present invention, and is a diagram showing a portion of a container body 4 cut away. Figure 2C The common components of the radon inhalation device 1 according to the first embodiment shown in FIG. Figure 2C The same reference numerals are used to denote components common to the radon inhalation device 1 according to the first embodiment, and descriptions overlapping with those of the radon inhalation device 1 according to the first embodiment will be omitted.

[0092] If the Fig.12 As shown in FIG. 1 , the radon derivation body 62 of the radon inhalation device 1 according to the present embodiment is different from the radon derivation body 14 of the radon inhalation device 1 according to the first embodiment.

[0093] That is, the radon guide body 62 of the radon inhalation device 1 according to the present embodiment is a cylindrical body with its front end separated into two branches, a filter 63 is provided at the upper part, and the upper end is connected to the gas flow path 15. Moreover, for the radon inhalation device 1, if the user inhales the gas containing radon in the radon storage chamber 8 through the gas flow path 15, the unnecessary substances in the gas are filtered out by the filter 63.

[0094] Such a radon inhalation device of the present embodiment can obtain the same effects as those of the radon inhalation device of the first embodiment.

[0095] <Third Embodiment>

[0096] In the first and second embodiments, the heating unit 6 for heating the inside of the radon generating container 5 of the radon inhalation device 1 is illustrated as being arranged inside the container body 4, but the present invention is not limited to this. The inside of the radon generating container 5 may also be heated by a heating unit arranged outside the radon generating container 5 (for example, inside the box 2, outside the lower surface of the container body 4, outside the side surface of the container body 4).

[0097] <Fourth embodiment>

[0098] Furthermore, a lighting unit (eg, LED lighting device) may be disposed inside the container body 4 for visually checking the remaining amount of the liquid 34 in the radon deriver 14 , the state of the filter gravel 35 , the state of the ore containing the radioactive substance 7 , and the like.

[0099] The lighting unit is preferably installed at a height position substantially in the center of the inner surface of the container body 4 that faces the radon derivation body 14 .

[0100] <Fifth Embodiment>

[0101] In addition, the radon inhalation device 1 of the first embodiment is a structure in which the central flow path 26 is connected to the gas flow path 15, and the side flow path 27 is connected to the radon storage chamber 8, but it is not limited to this, and the side flow path 27 may be connected to the gas flow path 15, and the central flow path 26 is connected to the radon storage chamber 8. In addition, in the case of this embodiment, the vents 32 and 33 are formed in the central flow path 26, and are not formed in the side flow path 27. In addition, in the case of this embodiment, the filter gravel 35 is preferably arranged at the lower part of the side flow path 27.

[0102] <Sixth embodiment>

[0103] In the above structure, an example is assumed for a small radon inhalation device (for example, a device with a radon generating container 5 having a capacity of about 5L). In a radon inhalation device 1 with a larger capacity, for example, a radon generating container 5 having a capacity of 50L or more, the bag 11 is also larger, so when the volume of the radon storage chamber 8 divided by the bag 11 is reduced, it is difficult for the user to reach into the interior of the container body 4 to lift the bag 11. In addition, when the radon inhalation device 1 is installed in a commercial facility, a hotel, etc., it is not preferable for an uncertain number of users to operate the interior of the radon inhalation device 1.

[0104] Therefore, if Fig.13A , 13B As shown, it is preferable to be able to suck the air in the outside air open chamber 10 with an air suction machine 110 to make the outside air open chamber 10 have a negative pressure to lift the bag 11, thereby increasing the volume of the radon storage chamber 8 without directly operating the bag 11 by hand.

[0105] Specifically, the radon generating container 5 comprises: a container body 4, which is formed by a lower shell member 71 and an upper shell member 81 as a cover member detachably assembled to the lower shell member 71, wherein a radioactive material-containing ore 7 (for example, a bag 70 made of non-woven fabric or the like and dried radium ore is powdered) and a heating unit 6 are accommodated inside the lower shell member 71; a bag 11 that divides the space inside the container body 4 (the space surrounded by the lower shell member 71 and the upper shell member 81) into a radon storage chamber 8 and an external air open chamber 10; a radon decompression body 14 that connects the radon storage chamber 8 and the outside of the container body 4; a gas flow path 15 installed on the radon decompression body 14; an air suction flow path 82 on which an air suction machine 110 can be installed to suck air from the external air open chamber 10; and an external air introduction flow path 72 that can introduce external air into the radon storage chamber 8.

[0106] The lower shell member 71 is formed in a substantially rectangular parallelepiped shape with an opening on the upper surface, and the upper shell member 81 is formed in a substantially rectangular parallelepiped shape with an opening on the lower surface, and the container body 4 is formed by assembling the lower shell member 71 and the upper shell member 81 in a manner that the respective opening surfaces face each other. The lower shell member 71 and the upper shell member 81 are preferably formed of a transparent or translucent material so that the inside can be visually confirmed, and in order to fix the state in which the upper shell member 81 is assembled to the lower shell member 71, a locking mechanism 90 composed of a buckle or the like is preferably provided.

[0107] The bag 11 is formed of a thin film of synthetic resin or rubber in a manner that allows for easy deformation, and has a bottomed cylindrical shape. The bag 11 is fixed between the upper opening of the lower shell member 71 and the lower opening of the upper shell member 81 with the opening ends opened, thereby partitioning the space enclosed by the lower shell member 71 and the upper shell member 81 into the radon storage chamber 8 and the outside air exposure chamber 10.

[0108] That is, Fig.14 As shown, the peripheral edge of the opening end of the bag 11 is clamped between a male flange 71f formed to protrude outward from the peripheral edge of the upper end opening of the lower shell member 71, and a female flange 81f formed on the upper shell member 81 in a manner engaged with the male flange 71f and protruding outward from the peripheral edge of the lower end opening of the upper shell member 81. In order to maintain this state, the lower shell member 71 and the upper shell member 81 are locked by the above-mentioned locking mechanism 90, and the radon storage chamber 8 is formed between the inner surface of the lower shell member 71 and the bag 11 (the space below the bag 11 in the space surrounded by the lower shell member 71 and the upper shell member 81), and the external air open chamber 10 is formed between the inner surface of the upper shell member 81 and the bag 11 (the space above the bag 11 in the space surrounded by the lower shell member 71 and the upper shell member 81).

[0109] The bag 11 can be displaced up and down with the portion sandwiched between the male flange 71f and the female flange 81f as the boundary, and the bottom of the bag 11 can be displaced from a state close to the inner surface of the bottom wall of the lower shell member 71 or its vicinity to a state close to the inner surface of the top wall of the upper shell member 81 or its vicinity. That is, by moving the bag 11 in the shell, it is possible to form a state in which the substantially entire shell interior becomes a chamber 10 open to the outside air (described later). Fig. 20B The state shown in FIG. 1 ), and the state in which the substantially entire shell is made into a radon storage chamber 8 (described later) Fig. 20A status shown).

[0110] like Fig.15As shown in FIG. 1 , the lower shell member 71 has bulges 73 bulging upward at four corners of the bottom wall 71a, and a sheet-shaped heating portion (planar heater) 6 of a predetermined width is laid on the inner surfaces of the pair of opposing side walls 71b and 71c and the upper surface of the bottom wall 71a in a manner avoiding the bulges 73. In this way, by arranging the heating portion 6 from the inner surface of one of the pair of opposing side walls 71b and 71c through the upper surface of the bottom wall 71a to the inner surface of the other of the pair of opposing side walls 71b and 71c (the heating portion is provided on three surfaces, namely, the inner surfaces of the side walls 71b and 71c and the upper surface of the bottom wall 71a of the lower shell member 71), even when a container body 4 having a large volume is used, the entire container is heated uniformly and efficiently, and it is difficult to generate temperature unevenness inside the container due to the ambient air temperature. As a result, radon of a stable concentration can be always supplied without being affected by the ambient air temperature.

[0111] Furthermore, above the heating portion covering the bottom wall 71a, an aluminum plate 74 ( Fig.15 Then, the radioactive substance-containing ore 7 is arranged on the upper surface of the aluminum plate 74. The radioactive substance-containing ore 7 is preferably arranged in the following manner: the radioactive substance-containing ore 7 in powder form is contained in a bag 70 of a non-woven fabric, and a necessary number of the bags are placed on the aluminum plate 74.

[0112] In addition, at the inner corner portion of the lower shell member 71, Figures 3A to 3D and Figures 4A to 4E The radon deriver 14 shown in the figure is fixed by an appropriate method such as double-sided tape, and the gas flow path 15 installed on the top 30 of the radon deriver 14 is pulled out to the outside of the container body 4. In this example, the radon deriver 14 is arranged in a manner that does not interfere with the heating unit 6. The heating unit 6 is arranged across three surfaces of the lower shell member as described above, has a large surface area, and has sufficient heat generation capacity, so even if it does not directly contact the radon deriver 14, it can fully heat the inside of the container body 4, heat the liquid inside the radon deriver, and increase the humidity.

[0113] The radon guide 14 used here is also the same as that used in the first embodiment ( Figures 3A to 3D , Figures 4A to 4E ) is the same structure as shown in FIG. 1 , so the description is omitted. The gas flow path 15 is as shown in FIG. Fig.16 As shown, the radon outlet 14 has a gas flow path installation hole 31 (see Figure 3A , 3B ) is provided with an L-shaped joint component (elbow joint 91), which is passed through a through hole 75 formed on the side wall 71b of the lower shell component 71 via a sleeve 92, and protrudes outward from the side wall 71b of the lower shell component 71.

[0114] In addition, if Fig.17 As shown in the figure, an L-shaped elbow joint 76 is installed on the side wall 71b of the lower shell member 71 in a manner penetrating through the sleeve 77 as a joint member constituting a part of the external air introduction flow path 72. The external air introduction flow path 72 is composed of the elbow joint 76 and the external air introduction pipe 78 connected to the portion of the elbow joint 76 protruding to the outside of the lower shell member 71, and the portion of the elbow joint 76 protruding to the inside of the shell is bent downward so as not to hinder the movement of the bag 11, and is extended downward along the inner surface of the side wall 71b of the lower shell member 71. In addition, the open end of the external air introduction pipe 78 is detachably sealed by a plug body 79.

[0115] On the other hand, the side wall 81b (see FIG. 1 ) is located on the side surface 81b of the upper shell member 81 and is located directly above the side wall 71b through which the air supply passage 15 and the external air introduction passage 72 of the lower shell member 71 pass. Fig.13A , 13B ),like Fig.18 As shown, an L-shaped elbow joint 83 is installed at the approximate center of the side surface 81b as a joint member constituting a part of the air suction flow path 82 so as to penetrate the upper shell member 81 via a sleeve 84. The air suction flow path 82 is composed of the elbow joint 83, an air suction pipe 85 connected to a portion of the elbow joint 83 protruding to the outside of the upper shell member 81, and an auxiliary pipe 86 connected to a portion of the elbow joint 83 protruding to the inside of the upper shell member 81.

[0116] In order not to hinder the movement of the bag 11 in the container body 4 and to prevent the bag 11 from adhering and hindering the suction of air, the portion of the elbow joint 83 protruding toward the inner side of the upper shell member 81 is bent upward by approximately 90 degrees, and the auxiliary pipe 86 is arranged to extend upward along the inner surface of the side wall 81b of the upper shell member 81. There is no particular limitation on the shape of the auxiliary pipe 86, but the front end opening 86a is directed upward, so that even when the air in the external air open chamber 10 is sucked from the outside of the shell through the air suction pipe 85, the bag 11 does not adhere to the front end opening and block it. In addition, a plurality of through holes 86b are formed at appropriate locations on the peripheral surface of the auxiliary pipe 86, and air can be sucked from the through holes 86b. Even if the front end opening 86a is blocked by the bag 11, air can be sucked from the through holes 86b on the peripheral wall of the auxiliary pipe 86.

[0117] The above radon inhalation device 1 can also be used in a hotel or the like by being stored in a cabinet (bedside table) 100 installed beside a bed. In this case, Fig.19A , 19BAs shown, the opening and closing door 101 arranged on the front surface of the cabinet 100 is opened to accommodate the radon inhalation device 1 in the cabinet 100, so that the gas flow path 15, the external air inlet pipe 78 of the external air inlet flow path 72, and the air suction pipe 85 of the air suction flow path 82 are pulled out to the front of the cabinet 100 through the opening and closing door 101.

[0118] The opening and closing door 101 is composed of a single door that is opened and closed by a hinge (not shown) provided on either side of the opening of the front surface of the cabinet 100, and the air suction pipe 85 is pulled out from a through hole 111 formed in the upper substantially central portion of the opening and closing door 101 that it faces. In addition, the external air introduction pipe 78 is also pulled out from a through hole 112 formed in the portion of the opening and closing door 101 that it faces.

[0119] For the above-mentioned air suction pipe 85 and external air introduction pipe 78, when the opening and closing door 101 is opened, they are in a state of being detached from the through holes 111 and 112 of the opening and closing door 101. When the opening and closing door 101 is closed, they are in a state of being inserted into the through holes 111 and 112 of the opening and closing door 101 and protruding to the front of the opening and closing door 101.

[0120] The external air introduction pipe 78 is sealed by inserting a plug 79 into the front end opening when the external air is not introduced into the radon storage chamber 8. On the other hand, the front end opening of the air suction pipe 85 does not need to be sealed with a plug, but it can be sealed with a plug or a cap to prevent the entry of garbage and the like.

[0121] like Fig.16 As shown, the gas flow path 15 includes, in addition to the elbow joint 91 fixed to the side wall 71b of the lower shell member 71 of the radon generating container 5, a first elbow joint 93 connected to the portion of the elbow joint 91 protruding from the side wall 71b and bent upward by approximately 90 degrees, a second elbow joint 95 fixed to the upper center of the opening and closing door 101 via a sleeve 94 and bent downward by approximately 90 degrees on the inner side of the opening and closing door 101, and a first elbow joint 93 connected to the portion of the elbow joint 91 protruding from the side wall 71b and bent upward by approximately 90 degrees, and a second elbow joint 95 fixed to the upper center of the opening and closing door 101 via a sleeve 94 and bent downward by approximately 90 degrees on the inner side of the opening and closing door 101. The cabinet 100 is composed of a joint hose 96 connected to the upper end opening of the pipe joint 93 and the lower end opening of the second elbow pipe joint 95, a T-shaped hose joint 97 connected to the portion of the second elbow pipe joint 95 protruding to the outside of the opening and closing door 101, a long flexible pipe 98 connected via the T-shaped hose joint 97, a third elbow pipe joint 99 installed at the front end of the pipe 98 and bent at about 90 degrees in an L shape, and a flanged nozzle component 58 installed at the front end of the third elbow pipe joint 99. Therefore, in this example, the pipe 98 is connected to the joint components (the second elbow pipe joint 95 and the T-shaped hose joint 97) fixed to the opening and closing door 101 and is arranged outside the cabinet 100.

[0122] The T-shaped hose connector 97 has a cap 97b detachably mounted on the open end of the middle joint 97a not connected to the second elbow connector 95 and the tube 98, and when it is necessary to add liquid to the radon deriver 14, the cap 97b can be removed to inject liquid from the middle joint 97a. In addition, the connector hose 96 is provided with a sufficient extra length so that even when the door 101 is opened and closed while the radon generating container 5 is stored in the cabinet 100, the connection between the first elbow connector 93 and the second elbow connector 95 is not damaged.

[0123] In addition, an L-shaped hook 102 capable of hooking the tube 98 of the gas flow path 15, the third elbow joint 99, or the flanged nozzle member 58 is provided at an appropriate position on the upper portion of the opening and closing door 101.

[0124] Furthermore, a gap 103 is formed between the upper end of the opening and closing door 101 and the top plate 100 a of the cabinet 100 , and the tube 98 can be housed in a space 104 formed between the upper surface of the radon generating container 5 and the top plate 100 a of the cabinet 100 through the gap 103 .

[0125] In the above structure, in order to use the radon inhalation device 1, when introducing external air into the radon storage chamber 8, the plug body 79 installed on the end of the external air introduction pipe 78 protruding from the opening and closing door 101 is removed, and in this state, the air suction machine 110 is inserted into the opening part of the air suction pipe 85 protruding from the opening and closing door 101, and the air suction machine 110 is operated to suck the air in the external air open chamber 10.

[0126] Then, the air in the external air open chamber 10 is sucked by the air suction machine 110 through the air suction flow path 82 and released to the outside of the radon generating container 5, so the pressure in the external air open chamber 10 decreases and becomes negative pressure. As the air in the external air open chamber 10 decreases, air is introduced into the radon storage chamber 8 through the radon guide 14 and the external air introduction pipe 78, and the bag 11 is lifted. When the air in the external air open chamber 10 is fully sucked, as shown in FIG. Fig. 20A As shown, the bag 11 is in contact with the inner surface of the upper shell member 81 over a wide area, and the space of the radon storage chamber 8 becomes maximum (approximately 50 liters).

[0127] At this time, the inner part of the shell of the elbow joint 83 connected to the air suction pipe 85 is bent upward, and the auxiliary pipe 86 is arranged to extend upward along the inner surface of the side wall 81b, so the bag 11 is not hooked on the elbow joint 83 and the auxiliary pipe 86, and the front end opening 86a of the auxiliary pipe 86 is not blocked. In addition, a plurality of through holes 86b are also provided on the peripheral wall of the auxiliary pipe 86, so even if a part of the through holes is blocked by the bag 11, the air in the external air release chamber 10 can be continuously sucked through the remaining through holes and the upper end opening.

[0128] After the outside air is taken into the outside air open chamber 10 in this way, a plug body 79 is installed at the open end of the outside air introduction pipe 78 protruding from the opening and closing door 101 to seal the outside air introduction flow path 72, so that the gas containing radon will not leak out of the radon storage chamber 8, and when the air containing radon in the radon storage chamber 8 is sucked, the outside air is not introduced into the radon storage chamber 8, thereby preventing the radon concentration in the radon storage chamber 8 from being reduced.

[0129] After that, when sucking the gas containing radon, the part of the gas flow path 15 hanging on the hook 102 is removed, and the tube 98 accommodated in the space 104 between the radon generating container 5 (container body 4) and the top plate 100a of the cabinet 100 is pulled out, and the tube 98 is guided to the desired position, and the suction nozzle member 58 is placed on the mouth and sucked. Thus, according to the same principle as the above-mentioned embodiment, the gas containing radon can be sucked from the radon storage chamber 8 via the radon deducting body 14 and the gas flow path 15.

[0130] When the gas containing radon stored in the radon storage chamber 8 is continuously sucked through the gas flow path 15 , the amount of air in the radon storage chamber 8 decreases, and accordingly the bag 11 also descends, and outside air flows into the outside air exposure chamber 10 through the air suction pipe 85 .

[0131] After the radon-containing air in the radon storage room 8 is roughly sucked out, Fig. 20B As shown, the bag 11 is brought close to the lower side shell member 71, and the space of the radon storage chamber 8 is almost gone. Afterwards, if there is an urgent desire to suck the air containing radon, the plug body 79 installed at the open end of the external air introduction pipe 78 is removed again, and the air suction machine 110 is inserted into the open end of the air suction pipe 85 in this state, and the air suction machine 110 is operated to suck the air in the external air open chamber 10.

[0132] Therefore, in the sixth embodiment described above, the bag 11 is lifted by sucking the air from the external air release chamber 10 using the air suction machine 110, thereby increasing the volume of the radon storage chamber 8, so the user does not need to take out the radon generating container 5 from the cabinet 100 and open the upper shell member 81 to lift the bag 11. Therefore, the user does not need to approach the radon generating container 5, so the locking device 120 ( Fig.19B ), so that the door 101 cannot be opened during normal use.

[0133] Furthermore, as described above, the gas containing radon is sucked together with the steam (water droplets), so the remaining amount of the liquid 34 stored in the lower part of the radon deductor 14 gradually decreases. Therefore, in order to replenish the liquid of the radon deductor 14, the liquid can be supplied from the middle joint 97a of the T-type hose joint 97 provided in the middle of the gas flow path 15. As for the supply position of the liquid, it is also possible to supply from any part of the gas flow path 15, but as described above, by pointing the middle joint 97a of the T-type hose joint 87 provided near the outer side of the opening and closing door 101 of the gas flow path 15 upward, removing the cap 97b attached to the front end thereof, and injecting the liquid through the middle joint 97a of the T-type hose joint 97 by a pipette or the like, the liquid can be easily supplied to the radon deductor 14 through the joint hose 96, the elbow joints 91, 93, 95.
