A kind of nebulizer for nebulae inhalation provided in this embodiment, comprising:
Atomisation device 1, being used for will be medicinal atomized；
Air accumulator 2；
The import of the air accumulator 2 is connected to the medicine outlet of the atomisation device 1；
Breathing mask 3；
The outlet of the feeding opening of the breathing mask 3 and the air accumulator 2, and the breathing mask 3 and the storage
The first Non-return air valve structure 31 is provided between gas tank 2, the drug for allowing to be atomized is from the air accumulator 2 to the breathing mask
3 flowings；
It is additionally provided with the second Non-return air valve structure 32 on the breathing mask 3, allows gas from the breathing mask 3
Chamber is expelled to outside.
From the foregoing, it will be observed that due to nebulizer in the prior art structure with exhaling, inhaling in patient treatment procedure between
It has a rest process, when air-breathing, drug can be formed by mist droplet or particle to be drawn into respiratory tract, and in expiration
When, drug can be made to be formed by mist droplet or particle and dispelled away through the stomata 313 being arranged on atomization therapentic equipment, disappeared
It is dispersed in the air, in turn results in the waste of drug.
So the nebulizer of the application is in the process sucked after atomisation device 1 will be medicinal atomized for patient
