[0039] The one-way flow member 3 includes: a limit fixing plate 301 and a sliding shaft 302. The limit fixing plate 301 is fixedly installed inside the insertion tube 203. Two limit fixing plates 301 are provided. Four through holes are provided on the limit fixing plate 301. The sliding shaft 302 is slidably installed on the limit fixing plate 301.

[0040] In the specific technical scheme of the embodiment of the present invention, the one-way flow component 3 also includes: a stop ball 303 and a tension spring 304, the stop ball 303 is fixedly mounted on the sliding shaft 302; the stop ball 303 is provided with a rubber coating on the outside; the stop ball 303 is attached to the inner side of the one-way limit ring 202; the tension spring 304 is sleeved on the sliding shaft 302; the tension spring 304 is connected between the sliding shaft 302 and the limit fixing plate 301, and the one-way flow component 3 is adopted, and the one-way flow structure is utilized, and the cannula 203 is located between the two one-way limit rings 202.

[0041] The above-mentioned technical solution utilizes a one-way flow component 3, which is more convenient for patients to use and smoother when performing breathing training. When the patient performs breathing training, the through holes provided at the top of the connecting tube 105 and the through holes provided at the bottom of the bottom plate 101 respectively play a role in pressure relief to ensure the fluidity of the airflow. The two one-way flow components 3 ensure that the patient can switch between exhalation and inhalation flexibly, which is more practical.

If the patient has hypoxia, fatigue or the breathing interval is too short, the blowing air pressure can no longer push the stop ball 303 to drive the sliding shaft 302 to touch the micro switch 403. At this time, the alarm prompt light 106 will not light up, which also reminds the patient that he needs to rest before training to avoid damage caused by excessive training. The higher the height of the micro switch 403 is adjusted, the lower the air pressure required for the patient to blow, so as to facilitate the patient to adjust according to his own situation.

[0045] Embodiment 2, based on embodiment 1, the abdominal breathing prompt module 5 comprises: a prompt piston cylinder 501 and a piston rod 502, wherein the side of the prompt piston cylinder 501 is made of iron;

The prompt piston cylinder 501 adopts a magnetic connection method and is modularly assembled and used, which is more flexible to use, improves the quality of the patient's breathing training, and improves the standardization of the patient's breathing training. The piston rod 502 can be used to quickly and easily know the degree of abdominal fluctuations without the patient having to feel it by hand.

[0049] The present invention provides a modular breathing training device, and the specific operation method thereof is as follows:

[0050] Step S1, first, place the breathing conduction component 1 on the table, and the patient performs blowing and inhaling training by holding the mouthpiece provided on the bellows 204 in his mouth. During the process, the airflow drives the floating ball 104 to float up, and the number of floating balls 104 floating up and the duration are observed, and the breathing resistance training can be performed. The one-way flow component 3 is used. When inhaling, the stop ball 303 at the bottom is fitted with the one-way limit ring 202 at the bottom under the action of air pressure for stop, and the stop ball 303 at the top will move down under the action of air pressure and separate from the one-way limit ring 202. At this time, the airflow circulates through the connecting tube 105, sucking in the three floating balls 104. At this time, with the elastic traction of the tension spring 304, the stop ball 303 at the top automatically moves up and resets when the patient stops inhaling.

[0051] Step S2, when the patient exhales, the upper stop ball 303 is pressed against the upper one-way limit ring 202 under the action of air pressure, and the lower stop ball 303 moves downward and separates from the lower one-way limit ring 202 under the action of air pressure. At this time, the airflow passes through the cavity of the bottom plate 101 to blow up the three floating balls 104;

[0052] Step S3, when the patient performs breathing training, the through hole provided on the top of the connecting tube 105 and the through hole provided on the bottom of the bottom plate 101 respectively play the role of pressure relief to ensure the flow of air, and the two one-way flow parts 3 ensure that the patient can switch between exhalation and inhalation flexibly;

[0053] Step S4, rotating the control hand wheel 402 drives the control threaded rod 401 to rotate, adjusting the control threaded rod 401 to drive the micro switch 403 to adjust the height, when the patient exhales, the air pressure pushes the stop ball 303 at the bottom to drive the sliding shaft 302 to touch the micro switch 403, at this time, the micro switch 403 channel control alarm indicator 106 lights up to indicate that the vital capacity air pressure meets the standard. If the patient is hypoxic, fatigued or the breathing interval is too short, the blowing air pressure can no longer push the stop ball 303 at the bottom to drive the sliding shaft 302 to touch the micro switch 403, at this time, the alarm indicator 106 will not light up, which also reminds the patient to rest before training, by winding the connecting belt 702 with the abdominal wrapping belt 602 around the patient's abdomen, and using the needle surface Velcro 603 and the wool surface Velcro 703 to stick.

[0054] Step S5, when the patient breathes abdominally, the abdomen will expand and fluctuate, at this time, the air pressure slider 701 can be squeezed to move outward on the abdominal air pressure control shell 601. As the patient breathes, the abdomen contracts. At this time, under the pull of the reset spring 704, the air pressure slider 701 can be retracted and reset. During this process, the air pressure generated inside the abdominal air pressure control shell 601 is introduced into the prompt piston cylinder 501, and the piston column 502 inside the air pressure control prompt piston cylinder 501 can move. The moving distance of the piston column 502 can be observed to show whether the abdominal fluctuation of abdominal breathing meets the standard.
