This medical nebulizer, comprise and produce being difficult to articulate of the atomize atomizing cup of vapour and the vapour that will atomize derivation atomizing cup, described being difficult to articulate comprises a body, described body has atomizing vapour access port, atomizing vapour export mouth, expiration outlet, described nebulizer access port connects the outlet of atomizing cup, constitute the derivation passage by the body inner space between atomizing vapour access port and the atomizing vapour export mouth, described expiration outlet is opened on the body tube wall of deriving passage; Also be provided with fluid collection device in the described derivation passage.
Described fluid collection device is to be installed in the baffle plate that stops of deriving vias inner walls.
Described derivation passage comprises first gas channel, second gas channel, connects the corner passage of first gas channel and second gas channel; Described first gas channel connects atomizing vapour access port, described second gas channel connects atomizing vapour export mouth, described expiration outlet is opened on the tube wall of second gas channel, and described fluid collection device is positioned at an end of the close corner passage of second gas channel.
Described expiration outlet is positioned at an end of the close corner passage of second gas channel, and described fluid collection device is between expiration outlet and corner passage.
Described first gas channel, second gas channel and corner passage are structure as a whole.
This utility model is compared with the prior art the beneficial effect that is had: be provided with fluid collection device in being difficult to articulate, the saliva of liquid after the gas liquefaction and user of preventing to atomize flows backwards and enters in the atomizing cup, avoid liquid medicine contamination, guaranteed the cleanliness factor of medicinal liquid, improved therapeutic efficiency.
