[0013] In order to make the present invention more obvious and easy to understand, preferred embodiments are described in detail as follows in conjunction with the accompanying drawings.

[0014] The utility model provides a dual-channel inhalation and exhalation trainer for respiratory rehabilitation training, which can train the inspiratory muscles during inhalation and the expiratory muscles during exhalation, and provide intra-airway oscillation. Figure 1As shown, it includes a trainer body 8, one end of the trainer body 8 is provided with a mouthpiece 1 communicating with the inner cavity of the trainer body 8 (the patient can inhale and exhale through the mouthpiece 1), the other end is provided with an inhalation port, the inhalation port is provided with an inhalation check valve 4 (the air at this position can only enter the trainer body 8 from the outside), the top of the trainer body 8 is provided with an exhalation port, the exhalation port is provided with an exhalation check valve 2 (the air at this position can only go out of the trainer body 8), and the top of the trainer body 8 is provided above the exhalation port. An exhalation oscillation ball 3 that oscillates in the airway is provided, and the bottom of the trainer body 8 is provided with a nebulizer interface 6 for connecting with a nebulizer 7. The patient can nebulize the medicine through the nebulizer 7 and inhale it into the lungs during inhalation. An inhalation resistance adjustment component 5 is provided in the trainer body 8 near the inhalation port.

[0015] The top of the trainer body 8 is located above the exhalation port and is connected to a ball cavity 31. A limiting hole 32 is provided in the middle position of the ball cavity 31. An exhalation oscillation ball 3 is provided in the ball cavity 31 on the side of the limiting hole 32 away from the exhalation port. The limiting hole 32 is a funnel-shaped structure. The exhalation oscillation ball 3 is located on the large mouth side of the funnel. The outer diameter of the exhalation oscillation ball 3 is larger than the minimum inner diameter of the limiting hole 32 (that is, the small mouth inner diameter of the funnel). A plurality of small holes communicating with the outside atmosphere are provided on the top of the ball cavity 31.

[0016] like Figure 2As shown, the inhalation resistance adjustment component 5 includes a sleeve 51 (equivalent to a fixed bracket, used to support the follower rod 52 and the limit rod 58), the sleeve 51 is fixed at a position near the inhalation port in the trainer body 8 (the sleeve 51 is fixed on the inner wall of the trainer body 8; the sleeve 51 can be fixed at the bottom, or both the bottom and the top can be fixed on the inner wall of the trainer body 8), a limit seat 54 is provided in the sleeve 51, the rotating rod 53 passes through the limit seat 54 and can rotate freely in the limit seat 54, one end of the rotating rod 53 passes through the limit seat 54, passes through the outer wall of the trainer body 8 and is fixedly connected to the adjusting knob 55, and the rotation of the rotating rod 53 can be achieved by rotating the adjusting knob 55, the side wall of the sleeve 51 is penetrated by the follower rod 52, and is limited on the sleeve 51 and can rotate along its own central axis, one end of the follower rod 52 The outer thread on the outer wall of the follower rod 52 is matched and connected with the inner thread of the rotating cylinder 57. A first baffle 56 is fixed to the end of the rotating cylinder 57 near the air inlet. A through hole is provided in the follower rod 52. One end of the movable rod 91 is movably inserted in the through hole of the follower rod 52, and the movable rod 91 can move freely in the through hole of the follower rod 52 along the length direction of the movable rod 91. A second baffle 92 is fixed to the other end of the movable rod 91. A spring 10 is sleeved on the movable rod 91. Both ends of the spring 10 abut against the first baffle 56 and the second baffle 92. The second baffle 92 is opposite to the air inlet, and the second baffle 92 abuts against the air inlet through the spring 10. The outer wall of the sleeve 51 is fixedly connected to one end of the limiting rod 58, and the other end of the limiting rod 58 passes through the first baffle 56, and the limiting rod 58 is parallel to the rotating cylinder 57, so that when the follower rod 52 rotates, the rotating cylinder 57 drives the first baffle 56 to move along the length direction of the limiting rod 58, thereby compressing or relaxing the tightness of the spring 10, that is, adjusting the suction force required for the outside air to push open the second baffle 92. Since the second baffle 92 blocks the air inlet, if you want to inhale, you need to increase the suction force to push open the second baffle 92 and expose the air inlet, so that air can enter the training device body 8.

[0017] The patient can adjust the inhalation resistance adjustment component 5 to adjust the tightness of the spring 10, thereby controlling the size of the inhalation resistance. Before inhalation, the nebulizer is turned on to continuously atomize the relevant medicine, and the patient tightly covers the mouthpiece 1 with his mouth. When the patient inhales, only when the inhalation pressure needs to be greater than the elastic force of the spring 10, the movable rod 91 moves, so that the second baffle 92 leaves the inhalation port, and the airflow enters through the inhalation check valve 4, and the patient starts to inhale.

[0018] When the patient exhales, the inhalation check valve 4 is closed, the exhalation check valve 2 is opened, and the exhalation oscillation ball 3 generates exhalation resistance through gravity, which can exercise the patient's exhalation muscles. At the same time, the exhalation oscillation ball 3 continues to swing up and down during the exhalation phase, driving the airflow to oscillate and promote sputum swing.
