Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation equipment technology, and in particular to a lung capacity training device. Background Technology

[0002] A spirometer is a device used to strengthen respiratory muscles, increase lung expansion capacity, and improve breathing control and coordination. The most common type is the three-ball spirometer, which consists of a shell, tubing, a ball, and a bellows. When the user inhales or exhales, the airflow pushes the ball upwards. By observing the height and number of times the ball rises, one can understand their inhalation or exhalation capacity.

[0003] After using the three-ball spirometer, the corrugated tube needs to be removed and rinsed to prevent bacterial growth and cross-infection. After repeated installation and disassembly, the corrugated tube may become loose at the end due to repeated stretching and friction. This can lead to loosening and air leakage at the end during subsequent use, affecting its usability. However, frequent replacement of the corrugated tube is quite costly.

[0004] Therefore, it is necessary to provide a new lung capacity training device to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a lung capacity training device that is simple and convenient to operate and can effectively prevent the corrugated tube cap from loosening and leaking air.

[0006] To solve the above-mentioned technical problems, the lung capacity training device provided by this utility model includes: a lung capacity training device body, a tubular air nozzle provided on the lung capacity training device body, a corrugated tube sleeved on the tubular air nozzle, an external threaded sleeve sleeved on the tubular air nozzle, an internal threaded sleeve sleeved on the external threaded sleeve, a push cylinder integrally formed on the side of the internal threaded sleeve away from the lung capacity training device body, and a plurality of L-shaped fixing blocks arranged in a ring array fixedly installed on the outer wall of the external threaded sleeve. A hexagonal slide rod is slidably installed through the tube. An arc-shaped plate is fixedly installed at one end of the hexagonal slide rod near the tubular air nozzle. An arc-shaped rubber pad is fixedly installed inside the arc-shaped plate. An end sleeve is fixedly fitted on the hexagonal slide rod. A first spring is fitted on the hexagonal slide rod. One end of the first spring is fixedly connected to the end sleeve, and the other end is fixedly connected to the L-shaped fixing block. A retaining block is fixedly installed at the end of the hexagonal slide rod away from the tubular air nozzle. The retaining block is in contact with the inner wall of the push cylinder.

[0007] Preferably, an operating wristband is fixedly installed on the outer wall of the internal threaded sleeve, and the outer wall of the operating wristband is provided with a plurality of anti-slip protrusions.

[0008] Preferably, the external threaded sleeve is slidably fitted on the outer wall of the tubular air nozzle, a collar is fixedly fitted on the outer wall of the tubular air nozzle, and a second spring is fitted on the outer wall of the tubular air nozzle. One end of the second spring is fixedly connected to the collar, and the other end is fixedly connected to the external threaded sleeve.

[0009] Preferably, the external threaded sleeve has multiple limiting slides arranged in a ring array, and multiple limiting sliders are fixedly installed on the outer wall of the tubular air nozzle. The multiple limiting sliders are respectively located in the multiple limiting slides and are slidably connected to the inner walls on both sides of the corresponding limiting slides.

[0010] Preferably, two handles are fixedly installed on the external threaded sleeve.

[0011] Preferably, a front limiting ring is fixedly sleeved on the outer wall of the tubular air nozzle, and the end of the external threaded sleeve away from the collar contacts the front limiting ring.

[0012] Compared with related technologies, the lung capacity training device provided by this utility model has the following beneficial effects:

[0013] This utility model provides a lung capacity training device. Through the arrangement of components such as an external threaded sleeve, an internal threaded sleeve, a push cylinder, an L-shaped fixing block, a hexagonal slide rod, an arc-shaped plate, an arc-shaped rubber pad, a first spring, and a second spring, when installing the bellows, simply dragging the external threaded sleeve to the left exposes a portion of the right end of the tubular air nozzle, allowing the user to easily fit the bellows onto the air nozzle. After the bellows is fitted, loosening the external threaded sleeve causes it to automatically return to its original position under the elastic force of the second spring. Multiple arc-shaped plates surround the outside of the bellows' end. Then, rotating the internal threaded sleeve clockwise moves the push cylinder to the right. Under the push cylinder's force, the multiple arc-shaped plates converge, and multiple arc-shaped rubber pads press tightly against the bellows' end.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-6 The lung capacity training device includes: a lung capacity training device body 1, which adopts the conventional design of existing three-ball lung capacity training devices. A tubular air nozzle 2 is provided on the lung capacity training device body 1, a corrugated tube 3 is fitted onto the tubular air nozzle 2, and an external threaded sleeve 4 is also fitted onto the tubular air nozzle 2. An internal threaded sleeve 5 is threaded onto the external threaded sleeve 4. A push cylinder 6 is integrally formed on the side of the internal threaded sleeve 5 away from the lung capacity training device body 1. The push cylinder 6 is trumpet-shaped, with its right end opening (i.e., the end away from the lung capacity training device body 1) gradually narrowing towards its left end opening. Multiple L-shaped fixing blocks 8 are fixedly installed on the outer wall of the external threaded sleeve 4 in a circular array. Each L-shaped fixing block 8 has a hexagonal sliding opening, through which a hexagonal sliding rod 9 is slidably installed. The hexagonal sliding rod 9 is close to the tubular air nozzle 2. An arc plate 10 is fixedly installed at the end. When multiple arc plates 10 are gathered together, they can be combined into an almost complete "cylinder". An arc rubber pad 11 is fixedly installed inside the arc plate 10. Under the pressure of the arc plate 10, the arc rubber pad 11 clamps the sleeve of the bellows 3. An end sleeve plate 13 is fixedly sleeved on the hexagonal slide rod 9. A first spring 12 is sleeved on the hexagonal slide rod 9. One end of the first spring 12 is fixedly connected to the end sleeve plate 13, and the other end is fixedly connected to the L-shaped fixing block 8. A support block 14 is fixedly installed at the end of the hexagonal slide rod 9 away from the tubular air nozzle 2. The support block 14 is in contact with the inner wall of the push cylinder 6. During the process of the push cylinder (6) moving to the left, under the elastic force of the first spring 12, the hexagonal slide rod 9 will gradually move away from the tubular air nozzle 2. Under the drive of the hexagonal slide rod 9, the arc rubber pad 11 separates from the tubular air nozzle 2.

[0023] In this embodiment, in order to facilitate the user to screw the internal threaded sleeve 5, an operating wristband 7 is fixedly installed on the outer wall of the internal threaded sleeve 5, and several anti-slip protrusions are provided on the outer wall of the operating wristband 7.

[0024] In this embodiment, the external threaded sleeve 4 is slidably fitted onto the outer wall of the tubular air nozzle 2. The external threaded sleeve 4 has multiple limiting slides arranged in a ring array. Multiple limiting sliders are fixedly installed on the outer wall of the tubular air nozzle 2. The multiple limiting sliders are located in the multiple limiting slides and are slidably connected to the inner walls on both sides of the corresponding limiting slides. A collar 15 is fixedly fitted onto the outer wall of the tubular air nozzle 2. A second spring 16 is fitted onto the outer wall of the tubular air nozzle 2. One end of the second spring 16 is fixedly connected to the collar 15, and the other end is fixedly connected to the external threaded sleeve 4. With the above design, when the user installs the bellows 3, the external threaded sleeve 4 can be dragged to the left, which will move the push cylinder 6, the arc plate 10, the arc rubber pad 11 and other components to the left. This will expose a part of the right end of the tubular air nozzle 2, which will make it easier for the bellows 3 to be fitted onto the tubular air nozzle 2.

[0025] In this embodiment, two levers 17 are fixedly installed on the external threaded sleeve 4 to facilitate dragging.

[0026] In this embodiment, when the bellows 3 is clamped and fixed, in order to limit the position of the external threaded sleeve 4, a front limiting ring is fixedly sleeved on the outer wall of the tubular air nozzle 2, and the end of the external threaded sleeve 4 away from the collar 15 contacts the front limiting ring.

[0027] The working principle of the lung capacity trainer provided by this utility model is as follows:

[0028] In the initial state, the right end of the external threaded sleeve 4 is in contact with the front limiting ring, i.e. Figure 3 The location shown;

[0029] When installing the bellows 3, first drag the external threaded sleeve 4 to the left using the lever 17. The external threaded sleeve 4 drives the push cylinder 6, the arc plate 10, the arc rubber pad 11, and other components to move to the left, compressing the second spring 16. As the above components move to the left, the right end of the tubular air nozzle 2 will gradually be exposed. Then, the bellows 3 sleeve is put onto the tubular air nozzle 2. After it is put on, release the lever 17. Under the elastic force of the second spring 16, the external threaded sleeve 4 will perform a reset movement (i.e., move to the right), and finally re-contact with the front limit ring. At this time, multiple arc plates 10 are all surrounding the outside of the bellows 3 sleeve. Then, rotate the internal threaded sleeve 5 clockwise using the operating ring 7. The internal threaded sleeve 5 rotates clockwise. During the movement, it will move to the right, which in turn will drive the pusher 6 to move to the right. Since the pusher 6 is trumpet-shaped, with its right end opening straight and its left end opening gradually narrowing, as the pusher 6 moves to the right, it will simultaneously push multiple abutment blocks 14 closer to the tubular air nozzle 2. Each abutment block 14 drives the corresponding arc plate 10 to move through the hexagonal slide rod 9. The arc plate 10 drives the arc rubber pad 11 to move. Finally, as the pusher 6 continues to move to the right, multiple arc rubber pads 11 will be tightly attached to the sleeve of the bellows 3. Multiple arc rubber pads 11 form a circular "hoop" that is clamped on the sleeve of the bellows 3, which can not only prevent air leakage, but also prevent the bellows 3 from loosening.

[0030] Compared with related technologies, the lung capacity training device provided by this utility model has the following beneficial effects:

[0031] This utility model provides a lung capacity training device. Through the arrangement of components such as an external threaded sleeve 4, an internal threaded sleeve 5, a push cylinder 6, an L-shaped fixing block 8, a hexagonal slide rod 9, an arc-shaped plate 10, an arc-shaped rubber pad 11, a first spring 12, and a second spring 16, when installing the bellows 3, simply drag the external threaded sleeve 4 to the left to expose a portion of the right end of the tubular air nozzle 2, allowing the user to easily fit the bellows 3 onto the tubular air nozzle 2. After the bellows 3 is fitted, loosen the external threaded sleeve 4, and the second spring... Under the elastic force of 16, the external threaded sleeve 4 will automatically reset, and multiple arc-shaped plates 10 will surround the outside of the bellows 3 sleeve. Then, by rotating the internal threaded sleeve 5 clockwise, the push cylinder 6 will move to the right. Under the push of the push cylinder 6, multiple arc-shaped plates 10 will converge, and multiple arc-shaped rubber pads 11 will press tightly against the bellows 3 sleeve. Overall, it has the advantages of simple and convenient operation, and can effectively prevent the bellows 3 sleeve from loosening and leaking air, which helps to improve the reliability of this lung capacity trainer.
