It should be noted that, when the medicine bottle 5 is used for the first time, the button 20 is pressed down, so that the locking member 3 is locked on the locking portion 211, the pre-pressing spring 22 is compressed, then the medicine bottle 5 is placed in the mounting cavity 100, the medicine bottle 5 abuts against the pushing seat 21, the pre-pressing spring 22 and the button 20, and the limiting portion 203 on the button 20 abuts against the top of the upper housing 10.
The medicine is sucked from the medicine sucking opening 120, the unlocking member 40 drives the locking member 3 to unlock from the locking portion 211, and the pre-pressing spring 22 pushes the pushing seat 21 downward, and the pushing seat 21 pushes the medicine bottle 5 downward, so that the medicine sucking and the medicine squeezing are performed in unison. Specifically, the patient inhales at the inhalation port 120, and the air pressure within the mounting cavity 100 is reduced, causing the seal 41 to rotate away from the vent hole 110; the sealing element 41 drives the rotating shaft 43 to rotate, and the rotation drives the driving blocks 42 at the two ends to rotate and compresses the torsion spring 44; the driving block 42 pushes the unlocking piece 40, the unlocking piece 40 moves inwards to unlock the locking piece 3 from the locking part 211, the pre-pressing spring 22 is released, and the pushing seat 21 is pushed downwards, so that the patient can inhale medicine and push medicine against the pushing seat 21, and the consistency of the hand opening is ensured. After stopping drug inhalation, the torsion spring 44 drives the sealing element 41 to reset and drives the driving block 42 and the rotating shaft 43 to reset; the button 20 is pressed down, so that the locking piece 3 is locked on the locking part 211 again, the pre-pressing spring 22 is compressed, the force of the pre-pressing spring 22 acting on the medicine bottle 5 through the pushing seat 21 is removed, the medicine bottle 5 drives the pushing seat 21, the pre-pressing spring 22 and the button 20 to move upwards and reset, and the next medicine suction can be performed, so that the cycle is performed.
In this scheme, this asthma respirator can solve the problem of patient's hand mouth uniformity, and can make things convenient for the weak group use that grip is little, and application range is wide, and the treatment is effectual.
