Second kind of common methods is to use the straight pipe of a T type, and this T type Guan Yiduan connects the patient oral cavity, and an end connects atomization medicine, and an end connects air.During treatment, user is generally bitten the one of which end, through eupnea; The medicine of atomizing directly enters the mouth by containing mouth; Have the normal physiology of respiration custom of the people of meeting, easy to use and advantages of cheap price, but T type straight pipe only plays the effect that connects atomization medicine and patient oral cavity, can not play blocking-up the gas that the patient breathes out; No matter be air-breathing or when exhaling; The gas of atomizing all can escape into the air from this end that connects air and go, thereby causes the waste of atomizing medicinal liquid, has influenced the curative effect of treatment.Reach therapeutic effect, just need to increase dose or treatment number of times, directly cause increasing the weight of of patient economy burden, also cause the prolongation of treatment time.

The third common methods is common to contain the oral cavity that mouth connects atomization medicine and patient with one, the gas that this method can not the blocks patient exhalation.The gas of breathing out not only possibly flow backwards, and pollutes the medicine in the atomizing cup, and, there is not special exhalation vents on the mouth owing to contain, the patient just has the sense of feeling suffocated if breathe for several times slightly continuously.If dehisce to take a breath this moment, atomization medicine blows to outside the mist pipe along with the wind-force in the atomization conduit, can cause the waste of medicine equally.

For addressing the above problem; 200520034324.3), medical nebulizer (application number: 201020136451.5), nebulizer (application number: 200720124443.7) and nebulizer (application number: 200720124441.8) etc. now occurred utilizing check valve to come the utility model of blocks patient breath, comprised that check valve contains mouth (application number:.The problem that these products can avoid breath to flow backwards, but all face a problem, the promptly air-breathing problem that is short of power.The medicinal liquid that no matter atomizes is to drive by compressed gas-driven or by ultrasonic atomizatio, and when the patient was air-breathing, unique source of gas was an atomization gas; And practice shows; These gases are thinner often, so under patient's situation of not becoming less severe, must feel when breathing repeatedly to feel suffocated; Thereby need dehisce ventilation again and again, the compliance of treatment is reduced greatly.

Summary of the invention

The technical problem that this utility model will solve provides a kind of user that both guaranteed and freely breathes, when guarantee exhaling again atomization chamber from movable sealing, the medical vaporizer suction tube that the medicinal liquid that effectively prevents to atomize spills.

For solving the problems of the technologies described above, this utility model adopts following technical scheme: a kind of medical vaporizer suction tube comprises shell; Said shell is a T shape, and the external tapping at shell two ends is respectively suction nozzle and air admission mouth, and shell upper is provided with air vent; The bottom is provided with the atomization gas inlet port; Be provided with the preceding thin film and the rear film of interlock in the shell, the upper end of preceding thin film is located at a side of air vent, and the upper end of rear film is located at the position near the air admission mouth.

The below of thin film and rear film was respectively equipped with front apron and back plate washer before this utility model was said, and a side of last air vent is provided with overhead gage.

Thin film was connected through thin plastic ties with rear film before this utility model was said.

This utility model compared with prior art makes full use of the advantage of check valve and T type straight pipe, with its combination, utilizes check valve to guarantee that user atomization chamber when exhaling prevents effectively that from movable sealing the medicinal liquid that atomizes from spilling; Bring into play T type straight pipe one end again and connected air, when the patient is air-breathing, not only sucked atomization medicine; And the suction outside air, meet the normal physiology of respiration custom of people, free and relaxed during use; Smooth and easy lastingly, have simple, efficient, can use repeatedly, advantage such as compliance is good.
