The other end of the pipe member 261 is connected to the first port portion 31 . The air that has flowed into the stopcock 30 from the first port portion 31 flows out from the second port portion 32 as indicated by arrow A in FIG. As shown in FIG. 1 , a filter 41 is connected to the second port portion 32 , and a mouthpiece 42 is connected to the filter 41 . Filter 41 and mouthpiece 42 constitute outlet section 40 . The opening of the mouthpiece 42 constitutes a mouth-side opening 421 for sucking in the air that has flowed in from the inlet 21 or blowing in exhalation.

The third port portion 33 constitutes the outlet portion 50 as shown in FIGS. The stopcock 30 is provided with a handle 311, and the user of the respiratory exercise device 1 holds the handle 311 to perform inhalation training.

Two pressure measurement ports 34 are provided on the upper portion of the second port portion 32 . An input port 701 of a pressure measuring device 70 is connected to each of the two pressure measuring ports 34 via pipe members 341 . The internal space of the second port portion 32 is partitioned by a mesh (not shown) through which air can flow. The mesh is provided at an intermediate position between the two pressure measurement ports 34 .

The pressure measuring instrument 70 has a central processing unit 71 (CPU), a power source section 72, a power input terminal section 73, a pressure display section 74, and a pressure sensor 75. It constitutes a pneumotachograph capable of measuring the pressure inside the stopcock 30 that changes due to breathing. The measured pressure is displayed on the pressure display section 74 which is arranged on the front panel of the respiratory exercise apparatus 1 and which is composed of a lateral deflection ammeter. Also, the flow rate of the air inside the stopcock 30 is configured to be output as an analog output from the BNC connector 76 on the back. The analog output from the BNC connector 76 is converted as appropriate, and is illustrated as a graph or the like on a personal computer (PC) or the like. A power cord is connected to the power input terminal portion 73, and the pressure measuring instrument 70 is driven by being supplied with AC 100V or DC 12V power from an AC-DC adaptor.

Next, inhalation training in respiration using the above-described breathing exercise device 1 will be described. The user of the respiratory exercise device 1 puts the opening of the mouthpiece 42 (oral-side opening 421 ) into the mouth, and inhales air through the opening of the mouthpiece 42 . As a result, the air outside the breathing exercise device 1 enters the flow path from the inlet 21 as indicated by the arrow A in FIG. It flows into the interior of the inlet portion 20 through the stopcock 30, passes through the filter 41, and flows into the user's body from the opening of the mouthpiece 42 (mouth-side opening 421). At this time, air resistance is generated according to the number of mesh bodies 24, and the user inhales air against the air resistance. As a result, the user can perform inhalation training in respiration with moderate air resistance.

After that, the air inhaled by the user flows from the body of the user through the mouthpiece 42 and the filter 41 through the opening of the mouthpiece 42, and as shown by the arrow B in FIG. It flows out to the outside of the breathing exercise device 1 through the configured outlet 52 .

The respiratory exercise device 1 configured as described above can exhibit the following effects.

As described above, the respiratory exercise device 1 is formed in the gas channel forming member 10 through which air can flow, the air inlet 21 formed in the gas channel forming member 10, and the gas channel forming member 10, It has an oral cavity side opening 421 for sucking air or exhaled breath from the inlet 21, and an outlet 52 formed in the gas flow path forming member 10 for exhaled breath that has flowed in from the oral cavity side opening 421.
An air resistance adjustment mechanism 22 capable of adjusting the resistance of the air flowing through the flow path during intake is provided in the flow path of air flowing in from the inlet 21 and flowing out from the oral cavity side opening 421 . The air resistance adjusting mechanism 22 includes a plurality of mesh bodies 24 arranged so as to block the flow path, and a mounted portion 25 capable of supporting a plurality of mesh bodies 24 . By changing the number of mesh bodies 24 arranged, the air resistance in the flow path is made variable.

Therefore, by changing the number of mesh bodies 24 attached to the attached portion 25, the air resistance in the air flow path can be changed. For this reason, the number of mesh bodies 24 is set to an appropriate number, and the air resistance suitable for the degree of breathing ability of the user using the respiratory exercise device 1 is set so that the user can perform breathing exercise using the respiratory exercise device 1. It is possible to Furthermore, since each mesh body 24 has an opening with a predetermined aperture ratio, it is possible to obtain air resistance corresponding to the number of mesh bodies 24 attached to the attachment part 25 .

Also, the mesh body 24 has a mesh portion 241 and an annular member 242 surrounding the mesh portion 241 . The mounting part 25 has a semi-cylindrical member 250 in which a plurality of arc-shaped grooves 251 are formed that are open upward and into which the mesh body 24 can be inserted.

Therefore, by inserting the flange portion of the flanged cylindrical portion 244 of the annular member 242 of the mesh body 24 into the deep groove portion 252 and inserting the cylindrical portion 243 into the shallow groove portion 253, the mesh body 24 can be easily removed. It can be attached to the attached portion 25, and the flange portion of the flanged cylindrical portion 244 of the annular member 242 of the mesh body 24 is removed from the deep groove portion 252, and the cylindrical portion 243 is removed from the shallow groove portion 253. By removing, the mesh body 24 can be easily removed from the mounting part 25 .

Moreover, the plurality of mesh bodies 24 are attached to the attached portion 25 while contacting each other to form a part of the flow path. Therefore, from the mesh body 24 installed closest to the inlet 21 to the mesh body 24 installed farthest from the inlet 21, the plurality of mesh bodies 24 are in airtight contact with each other. An air flow path can be formed in which air does not leak from the middle, that is, between adjacent mesh bodies 24 . Therefore, it is possible to simplify the configuration of the mounting portion 25 .

The present invention is not limited to the embodiments described above, but can be implemented in various forms within the scope of the claims. For example, the configuration of the gas flow path forming member, the inlet, the oral cavity side opening, the outlet, the air resistance adjustment mechanism, etc. is the same as the inlet section 20, the outlet section 50, the stopcock 30, the filter 41, the mouthpiece 42, the valve 51, the mounting portion 25, the mesh body 24, and the like. Therefore, for example, although the number of mesh bodies 24 that can be attached to the attached portion 25 is five, the number is not limited to this number.
