[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0024] Example: An adjustable back percussion and sputum suction device, such as Figure 1 As shown, it includes a first rod 1, and a second rod 2 is slidably inserted into the top end of the first rod 1, as shown. Figure 2As shown. A fastening assembly 3 is provided between the first rod 1 and the second rod 2, allowing the user to adjust the extension and retraction of the entire back-patting and expectoration device to adapt to different usage needs. An adapter 10 is connected to the end of the second rod 2, and a first connecting seat 4 is connected to the end of the adapter 10. A rotating component 5 is rotatably fitted to the first connecting seat 4, and a second connecting seat 6 is rotatably fitted to the rotating component 5. A cover 7 is provided on one side of the second connecting seat 6; an air cushion 8 is provided on the bottom surface of the cover 7. The air cushion 8 can change the softness and fit of the cover 7 in contact with the body after inflation, making the back-patting process more comfortable, and may also help to better transmit the percussion force to achieve the expectoration effect. An inflation valve 9 is fixedly connected to the top of the air cushion 8, communicating with the inner cavity of the air cushion 8, for inflating the air cushion 8, allowing the air cushion 8 to adjust the internal air pressure as needed, thereby adjusting the softness and shape of the air cushion 8.

[0025] Specifically, such as Figure 3-5 As shown, the fastening assembly 3 includes a locking sleeve 301 sleeved on the outer wall of the top end of the first rod 1. The side wall of the locking sleeve 301 has a communicating cavity, and a clamping member 303 is provided in the communicating cavity. The locking sleeve 301 has a set of through holes, and the clamping member 303 has a pair of positioning pins that cooperate with the through holes. The locking sleeve 301 and the clamping member 303 are connected by the positioning pins and the through holes, and the communicating cavity on the side wall of the locking sleeve 301 provides space for the clamping member 303. A buckle 304 that abuts against the clamping member 303 is rotatably connected to the locking sleeve 301. The first rod 1 has a first groove 101 and a second groove 102 that are oppositely arranged. The second rod 2 has a third groove 201 that slides with the first groove 101 and a fourth groove 202 that slides with the second groove 102. The upper end of the first groove 101 has a clamping notch 103. The clamping member 303 abuts against the second rod 2. When it is embedded in the clamping notch 103 of the first rod 1 and abuts against the third groove 201 of the second rod 2, the relative positions of the first rod 1 and the second rod 2 can be fixed, thereby achieving the tightening after adjustment. The clamping member 303 is embedded in the clamping notch 103 and abuts against the third groove 201. The inner wall of the locking sleeve 301 is provided with a limiting protrusion 302 that fits into the second groove 102. The limiting protrusion 302 cooperates with the clamping member 303 to restrict the rotation of the second rod 2. The latch 304 includes a clamping post 3041 that abuts against the clamping member 303 and a lever 3042 that fits against the outer wall of the locking sleeve 301. The clamping post 3041 has an eccentric hole along the axial direction. The locking sleeve 301 is provided with a rotating shaft. The latch 304 passes through the eccentric hole and rotates eccentrically to the locking sleeve 301. The wrench 3042 is convenient for users to operate. When the wrench 304 is turned, the clamping post 3041 abuts against the locking member 303, thereby adjusting the position of the locking member 303 and achieving the purpose of tightening or loosening the first rod 1 and the second rod 2.

[0026] Specifically, such as Figure 6 As shown, the first connecting seat 4 includes a pair of first connecting arms 401, and the first connecting arms 401 are provided with first rotating holes 402. Figure 7 As shown, the rotating component 5 is provided with a first rotating shaft 501 and a second rotating shaft 502 arranged in a cross shape. Figure 8 As shown, the second connecting seat 6 includes a pair of second connecting arms 601, with second rotating holes 602 at both ends of the second connecting arms 601. The first rotating shaft 501 is rotatably engaged with the first rotating hole 402. The first rotating shaft 501 is threadedly connected to a set of first adjusting screws 503 via threaded holes. The first adjusting screws 503 are provided with first limiting rings 505, which abut against the end face of the first rotating hole 402. The second rotating shaft 502 is rotatably engaged with the second rotating hole 602. The second rotating shaft 502 is threadedly connected to a second adjusting screw 504 via threaded holes. The second adjusting screw 504 is provided with a second limiting ring 506, which abuts against the end face of the second rotating hole 602.

[0027] This invention, through the sliding connection of the first rod 1 and the second rod 2 and the setting of the fastening component 3, allows the user to adjust the length of the back-patting and expectorating device according to actual needs. This better adapts to the operational requirements of users of different heights and body types, or in different usage scenarios, improving comfort and convenience. The rotating engagement structure between the first connecting seat 4, the rotating component 5, and the second connecting seat 6 allows for adjustment of the angle of the cover 7, helping the user to better conform to the patient's back curve during back-patting and find the most suitable percussion angle, thereby improving the expectoration effect. The air cushion 8 at the bottom of the cover 7 and the inflation valve 9 connected to the top of the air cushion 8 increase the cushioning when the cover 7 contacts the patient's back, increasing patient comfort. Furthermore, the fastening component 3, through the cooperation of the locking sleeve 301, the clamping component 303, and the buckle 304, effectively fastens the first rod 1 and the second rod 2 together. This mechanical structure achieves a stable connection, ensuring a firm connection and the overall structural stability of the back-patting and expectorating device, which is conducive to continuous and effective back-patting operations. The rotating component 5 of this utility model cooperates with the first connecting seat 4 and the second connecting seat 6 through the first rotating shaft 501 and the second rotating shaft 502, and uses the first adjusting screw 503, the first limiting ring 505, the second adjusting screw 504 and the second limiting ring 506 to fix the angle, so that the angle can be stably maintained after adjustment.

[0028] Working principle

[0029] When the latch 304 is opened, the clamping post 3041 of the latch 304 abuts against the locking member 303, and the locking member 303 slides in the communicating cavity. The clamping post 3041 no longer applies pressure to the locking member 303. The limiting protrusion 302 on the inner wall of the locking sleeve 301 and the locking member 303 no longer restrict the sliding of the second rod 2. Then, the second rod 2 is pulled or pushed to slide inside the first rod 1, thereby adjusting the length of the entire back-patting and sputum-expelling device.

[0030] When the latch 304 is closed, the clamping post 3041 of the latch 304 abuts against the locking member 303, and the locking member 303 slides in the communicating cavity. Under the action of the clamping post 3041, the locking member 303 abuts against the third groove 201 of the second rod 2. The locking member 303 provides a squeezing force to the second rod 2. Under the action of the squeezing force, the limiting protrusion 302 on the inner wall of the locking sleeve 301 cooperates with the locking member 303 to restrict the sliding of the second rod 2, thereby fixing the extension and retraction of the sputum suction device.

[0031] The first rotating shaft 501 on the rotating component 5 is rotatably engaged with the first rotating hole 402 on the first connecting arm 401 of the first connecting seat 4, and the angle is fixed by the first adjusting screw 503 and the first limiting ring 505. The second rotating shaft 502 is rotatably engaged with the second rotating hole 602 on the second connecting arm 601 of the second connecting seat 6, and the angle is fixed by the second adjusting screw 504 and the second limiting ring 506, thereby realizing the adjustment of the angle.

[0032] Inflating the air cushion 8 via the inflation valve 9 changes the internal air pressure, thereby adjusting its firmness and shape. Inflated air cushion 8 increases cushioning when the cover 7 contacts the patient's back, making the back-patting process more comfortable and also helping to better transmit the percussion force for effective sputum expectoration.

[0033] In summary, this invention can increase the comfort of patients during the back-patting and coughing process, and has the advantages of adjustable length and back-patting angle.
