Atomizing device connected in noninvasive breathing machine pipeline

The utility model discloses an atomizing device connected in a noninvasive breathing machine pipeline. The device comprises a barrel-type connecting pipe, a T-shaped pipe, a medicine storage bottle and an oxygen connecting pipe. In an atomizing process, one end of the T-shaped pipe is connected with a breathing machine face mask through the barrel-type connecting pipe, the other end of the T-shaped pipe is connected with a gas leakage valve, and the gas leakage valve is connected with the breathing machine through a breathing machine long pipeline. All the above-mentioned parts form a sealed breathing loop. The device is simple to manufacture and simple to connect, allows sucked medicine amount to be increased and enables improvement in curative effects. Medicine that is not sucked in is not left in the mouth, so that side-effects of the medicine is reduced. Patients can complete an atomization treatment without off-lining, so that the device is easy to accept with good effects.
