Advantageous effects

The invention relates to a visual sputum excretion breathing trainer, wherein an expiration elbow is connected to a base through a connector before use, and a connecting wire in an information processing module is inserted into corresponding sockets of a display screen and a sensor according to requirements.

When the sputum loosening function is used, the expiration bent pipe is connected to the sputum loosening device port through the connecting port. The patient inhales for 1-2 seconds, the mouthpiece containing the expiratory elbow is held for stable and continuous expiration after the patient holds breath for 1-2 seconds, the expired gas gushes into the sputum loosening pipe, the vibration baffle blocks the gas outlet under the elastic action of the elastic ring, and positive pressure is generated in the sputum loosening pipe; with the increase of the positive gas pressure, the positive gas pressure overcomes the elasticity of the elastic ring to push the vibration baffle plate to open, the gas is discharged, and the opening angle of the elastic ring is increased; along with gaseous letting out, the not hard up intraductal pressure of sputum reduces, and vibration baffle resets under the elastic force effect that the elastic ring produced, blocks the gas outlet of the not hard up pipe of sputum, produces the malleation in the not hard up pipe of sputum. So relapse, intermittent type nature increases the intrabronchial pressure, makes the expired gas produce the vibration, and the vibration frequency reaches resonance with human lung frequency, and the vibration of bronchus PEP (positive pressure breathing) is enlargied, and patient's trachea wall mucus is not hard up.

When the sputum moving and breathing training functions are used, the expiration elbow is connected with the sputum moving device through the connecting port, and the connecting wire in the information processing module is inserted into the corresponding socket of the display screen and the sensor according to requirements. The patient inhales for 1-2 seconds, the mouthpiece containing the expiratory elbow stably and continuously exhales after the patient holds breath for 1-2 seconds, the gas flows through the sensor and flows into the ACAPELLA tube body, the ACAPELLA head seals the air outlet end of the ACAPELLA tube body by the water ball cushion in the ACAPELLA tube body under the elastic action of the rubber elastic belt, positive pressure is generated in the ACAPELLA tube body, and the patient blows to overcome the elastic force of the rubber elastic belt to push the ACAPELLA head to move forwards along with the increase of the gas pressure; when the ACAPELLA head moves for a distance to enable the air outlet holes to be positioned outside the positioning retaining ring, the air is discharged through the air outlet holes, the pressure of the air in the ACAPELLA pipe body is reduced, and the ACAPELLA head moves reversely under the elastic action of the rubber elastic band; after the air outlet hole returns to the inner position of the positioning baffle ring, the air pressure rises again, and the ACAPELLA head moves forward again. According to the different dynamics of patient's blowing, ACAPELLA head moves forward to different exhaust vent departments to do quick reciprocating motion in this exhaust vent department of giving vent to anger, so relapse, drive the air vibration, and then drive the inner wall cilia of airway depths and produce resonance, promote not hard up sputum and push the thick trachea in people's upper portion from bottom to top, in case the sputum gets into thick trachea, just discharge through coughing very easily in vitro.

The invention uses the visual sputum excretion and respiration trainer with two functions to lead the patient to obtain the combined treatment of airway vibration and PEP positive pressure therapy when in use, in the process of expiration, the portable positive pressure sputum excretion and respiration trainer in two use modes drives the air to generate vibration, further drives cilia at the inner wall of the deep part of the airway to generate resonance, thus leading the sputum and other secretions adhered in the airway to loosen and move.
