Operation principle of the present invention:
When servomotor starts, the driving gear being arranged on motor output shaft drives the Left Drive gear and the right travelling gear that are engaged with to rotate backward, thereby drive left-hand rotation dish and right-hand rotation dish to rotate backward, left-hand rotation dish and right dial rotation drive respectively left active pin and the motion of right active pin, when left active pin and right active pin move to the height point position of left cam and right cam, left, a left side is inserted respectively in right active pin rear end, in the through hole of right baffle plate lower end, and drive left connecting rod link and right connecting rod hinge to swing, make to be fixed on left push handle on left connecting rod link and right connecting rod hinge and right push handle compressing gasbag from DaoⅡ position, I position, oxygen in extruding gasbag is transported to disease population from exhaustor, left-hand rotation dish and right-hand rotation dish continue motion, left and right active pin is rotated further, when it moves to the low dot location of corresponding cam, active pin and baffle plate are thrown off, also throw off with left and right connecting rod link, the oxygen of coming in by the air inlet pipe of air bag makes again left and right push handle get back to position I from position II, left and right push handle moves to position II from position I like this, then gets back to position I from position II, and regular extruding gasbag like this makes in the regular patient's of delivering to of oxygen wherein mouth, thereby completes continuous oxygen uptake process.
Because servomotor can be digital control, can stepless time adjustment and there is the features such as speed governing is stable, so by adjusting the speed of servomotor, just capable of regulating is controlled the strength of required pusher grip, thereby obtains required oxygen uptake frequency and oxygen absorbed.
Owing to adopting technique scheme, it is high that the present invention has stability, easy to operate, adjusts the advantages such as simple, and having solved patient and family members can the own easily practical problem of control operation respiratory organ.
