when the breathing mask is used, the patient starts to breathe out, the breathed-out gas enters the ventilation cavity 11 through the ventilation pipe 50, the breathed-out gas enters the bottom of the breathing pipe 21 and is concentrated on the bottom surface of the impedance plate 23, the weight of the impedance plate 23 and the adjusting rings 24 is overcome through the gas, the impedance plate 23 and the adjusting rings 24 are driven to move upwards, the gas flows to the top of the inside of the breathing pipe 21 through a gap between the impedance plate 23 and the baffle ring 22 and then flows to the outside, after the expiration is finished, inspiration is started, negative pressure is generated in the ventilation cavity 11 at the moment, oxygen in the oxygen storage box 32 pushes away the first one-way flip 33 and outside air pushes away the second one-way flip 60, and the oxygen and outside air enter the ventilation cavity 11 and are inhaled into the body through the mouth of the patient. And the flow rate of oxygen in the intake pipe 31 can be regulated by adjusting the control valve 37 so as to gradually restore the lungs of the patient.

The invention has the beneficial effects that: according to the postoperative lung respiration training device, the number of the adjusting rings 24 on the impedance plate 23 is selected according to the requirement of the expiratory strength of a patient, and the other adjusting rings 24 move upwards to a certain height through the adjusting piece 27, so that the weight of the impedance plate 23 and the adjusting rings 24 becomes the expiratory impedance strength of the patient, and the expiratory resistance of the patient can be adjusted according to the rehabilitation stage of the patient, so that the rehabilitation speed of the lung function is accelerated; simultaneously, the arrangement of the air inlet assembly 30 enables continuous expiration and inspiration, the air hood 40 is not required to be taken off for inspiration after expiration is finished, and the air inlet assembly 30 can provide sufficient oxygen for a patient, so that the oxygen and the outside air are provided simultaneously, and the defect that the subsequent expiration training effect is poor due to the fact that sufficient oxygen content cannot be inhaled from the outside only after expiration training is avoided.

The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention, and are intended to be included within the scope of the appended claims and description.
