Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a breathing training device for respiratory nursing. Background Art

[0002] For patients with lung diseases (such as emphysema, COPD, etc.) or who have undergone lung surgery, breathing training devices are often used to rehabilitate their breathing ability. In addition, for healthy people, breathing training devices can also be used to improve vital capacity. Under the guidance of the breathing training device, the patient takes a deep breath, inhales air into the lungs, and then exhales. By constantly inhaling and exhaling, it helps the patient to exercise the lungs. During breathing training, due to different foundations and purposes, everyone has different requirements for breathing resistance. Even in the same set of breathing training, changing breathing resistance before and after can achieve better training effects. However, the breathing resistance of most existing breathing training devices is fixed and cannot be adaptively adjusted, which makes the training insufficient and thorough, thereby greatly reducing the training effect.

One ends of the first extrusion plate sliding groove 12, the second extrusion plate sliding groove 13 and the third extrusion plate sliding groove 14 are all set as arc surfaces.

[0036] Among them, Figure 8 , Fig. 9 As shown, the breathing resistance adjustment component 30 includes an outer ring 31, a connecting plate 32, an inner ring 33, an extrusion plate placement groove 34, an extrusion plate 35, a second spring 36 and a rotating shaft 37.

[0039] The outer ring 31 is rotated counterclockwise, and the outer ring 31 drives the inner ring 33 to rotate counterclockwise through the connecting plate 32, and the inner ring 33 drives the first extrusion plate 351, the second extrusion plate 352 and the third extrusion plate 353 to rotate counterclockwise. Because of the setting of the central angle of the first extrusion plate sliding groove 12, the second extrusion plate sliding groove 13 and the third extrusion plate sliding groove 14, the first extrusion plate 351 will first move into the first extrusion plate sliding groove 12, and under the elastic force of the second spring 36, the first extrusion plate 351 rotates with the rotating shaft 37 as the center of the circle, thereby squeezing the breathing training inner cylinder 20, increasing the movement resistance of the breathing training inner cylinder 20, and continuing to rotate the outer ring 31 counterclockwise, the second extrusion plate 35 2 and the third squeezing plate 353 will move to the second squeezing plate sliding groove 13 and the third squeezing plate sliding groove 14 in turn, and squeeze the breathing training inner cylinder 20 in turn, continuously increasing the movement resistance of the breathing training inner cylinder 20, and adjusting the breathing resistance by rotating the outer ring 31 counterclockwise. When the outer ring 31 is rotated clockwise, one end of the first squeezing plate sliding groove 12, the second squeezing plate sliding groove 13 and the third squeezing plate sliding groove 14 is set as an arc surface, which is conducive to moving the first squeezing plate 351, the second squeezing plate 352 and the third squeezing plate 353 back to the first squeezing plate sliding groove 12, the second squeezing plate sliding groove 13 and the third squeezing plate sliding groove 14 respectively.

[0040] Among them, Fig.10 , Fig.11 As shown, the breathing training inner cylinder 20 is provided with a second air outlet hole 21, an air outlet baffle rotating groove 22, an air outlet baffle 23, a telescopic column 24, a first spring 25, a threaded rod 26 and a threaded rod moving groove 27.

The first spring 25 is disposed in the telescopic column 24 .

[0042] Furthermore, one end of the threaded rod 26 is fixedly connected to the inner end of the breathing training outer cylinder 10, and the other end of the threaded rod 26 passes through the bottom wall of the breathing training inner cylinder 20 and is movably set in the threaded rod moving groove 27, and the threaded rod 26 is threadedly connected to the air outlet baffle 23 through the threaded rod moving groove 27. There is a through hole on the breathing training inner cylinder 20 for the movement of the threaded rod 26, and the breathing training inner cylinder 20 is not threadedly connected to the threaded rod 26.

[0043] When exhaling, the exhaled gas pushes the breathing training inner cylinder 20 to move. At this time, the telescopic column 24 contracts and the first spring 25 is compressed. When the breathing training inner cylinder 20 moves to the position where the threaded rod 26 is threadedly connected to the air outlet baffle 23, the threaded rod 26 drives the air outlet baffle 23 to rotate, thereby opening the second air outlet hole 21, and the gas in the breathing training inner cylinder 20 is discharged through the second air outlet hole 21. At this point, a breathing training process is ended. Under the elastic force of the first spring 25, the breathing training inner cylinder 20 returns to the initial position, and the threaded rod 26 drives the air outlet baffle 23 to rotate in the opposite direction, thereby closing the second air outlet hole 21.

[0044] Among them, Figure 2 , Figure 4 As shown, the breathing training outer cylinder 10 is also provided with an annular frame 11, an inner ring rotating groove 15, a connecting plate rotating groove 16, a breathing mask 17, a first air outlet 18 and a handle 19. The annular frame 11 is fixedly arranged in the breathing training outer cylinder 10, and the breathing training inner cylinder 20 is movably arranged between the annular frame 11 and the inner side wall of the breathing training outer cylinder 10. This arrangement ensures that the exhaled gas is always located in the annular frame 11 and the breathing training inner cylinder 20, thereby avoiding gas leakage and affecting the training effect.

[0045] Furthermore, the inner ring rotation groove 15 is located at the outer ends of the first extrusion plate sliding groove 12 , the second extrusion plate sliding groove 13 and the third extrusion plate sliding groove 14 , and the inner ring rotation groove 15 is located at the inner end of the connecting plate rotation groove 16 .

[0047] Furthermore, the breathing mask 17 is fixedly arranged on one end of the breathing training outer tube 10 close to the annular frame 11, and the patient exhales into the breathing training outer tube 10 through the breathing mask 17. The first air outlet 18 is located on the end of the breathing training outer tube 10 away from the annular frame 11, and the gas exhausted from the second air outlet 21 is discharged through the first air outlet 18. The handle 19 is fixedly arranged on the arc-shaped side surface of the breathing training outer tube 10, and the handle 19 helps the patient to hold the device.

[0048] When in use, first select a suitable breathing resistance according to the patient's own situation, rotate the outer ring 31 counterclockwise, the outer ring 31 drives the inner ring 33 to rotate counterclockwise through the connecting plate 32, and the inner ring 33 drives the first squeezing plate 351, the second squeezing plate 352 and the third squeezing plate 353 to move to the first squeezing plate sliding groove 12, the second squeezing plate sliding groove 13 and the third squeezing plate sliding groove 14 in turn, and squeezes the breathing training inner cylinder 20 in turn, continuously increasing the movement resistance of the breathing training inner cylinder 20. After adjusting the breathing resistance, the patient takes a deep breath, and then places the breathing mask 17 on the mouth and nose, and the exhaled gas enters the annular frame 11 and the breathing mask 17 through the breathing mask 17. The breathing training inner cylinder 20 is sucked into the breathing training inner cylinder 20 and pushed to move the breathing training inner cylinder 20. At this time, the telescopic column 24 is contracted and the first spring 25 is compressed. When the breathing training inner cylinder 20 moves to the position where the threaded rod 26 is threadedly connected with the air outlet baffle 23, the threaded rod 26 drives the air outlet baffle 23 to rotate, thereby opening the second air outlet 21, and the gas in the breathing training inner cylinder 20 is discharged through the second air outlet 21. At this point, a breathing training process is ended. Under the elastic force of the first spring 25, the breathing training inner cylinder 20 returns to the initial position, and the threaded rod 26 drives the air outlet baffle 23 to rotate in the opposite direction, thereby closing the second air outlet 21, and the above process is repeated to perform breathing training.

[0049] The cylinder of the utility model is used to adjust the sliding resistance of the breathing training inner cylinder in the breathing training outer cylinder by arranging a breathing resistance adjustment component in the breathing training outer cylinder, thereby effectively solving the problem that the existing breathing training device cannot adjust the breathing resistance. The breathing resistance adjustment component is provided with a first squeezing plate, a second squeezing plate and a third squeezing plate. The breathing training outer cylinder is provided with a first squeezing plate sliding groove, a second squeezing plate sliding groove and a third squeezing plate sliding groove with successively decreasing central angles. By rotating the outer ring, the first squeezing plate, the second squeezing plate and the third squeezing plate can be driven to move into the first squeezing plate sliding groove, the second squeezing plate sliding groove and the third squeezing plate sliding groove in turn, and squeeze the breathing training inner cylinder in turn, continuously increasing the moving resistance of the breathing training inner cylinder, so that the appropriate breathing resistance can be selected according to the patient's own situation. The operation is simple and better training effect can be achieved.
