However, it has the following disadvantages: inhale the phlegm in-process, the sputum easily gets into suction device and negative pressure device under negative pressure device's effort, easily makes the sputum pollute negative pressure device, and the sputum is difficult for adsorbing the sputum completely in the deformation portion is aerifyd by the inside backward flow of suction device when easily making the device stop using.

Still like disclose a paediatrics sputum aspirator in applying publication number CN207356300U, including inhaling phlegm pipe, exhaust tube and negative pressure suction apparatus, the one end of inhaling the phlegm pipe is connected with the one end of separator tube through first connection seat detachably, the other end of inhaling the phlegm pipe is equipped with inhales the phlegm head, the other end and the negative pressure suction apparatus of exhaust tube are connected, the bottom of separator tube is connected with out the phlegm pipe and passes through accurate control male length, does not cause the injury to the patient. However, it has the following disadvantages: inhale the phlegm in-process, can't fix children's oral cavity position, easily make children move indiscriminately at inhaling the phlegm in-process for the phlegm pipe causes the damage to children's oral cavity and throat, and during the insertion, can't carry out angle adjustment according to the inserted position, can't absorb the sputum comprehensively.

Further, as disclosed in the patent with application publication No. CN207186857U, a rapid sputum aspirator special for pediatricians comprises a sputum aspirator body; the sputum aspirator body mainly comprises a liquid storage bottle and a suction tube; the outer part of the suction tube, which is positioned on the liquid storage bottle, is sleeved with a sleeve, and the sleeve is connected with an injector through a joint; the straw end rotates and is connected with rotary joint, rotary joint fixedly connected with suction head, and rotary joint right side surface cleans the internal phlegm of children through the brush through hot pressing mode fixedly connected with brush, stirs, has reduced and has inhaled the phlegm degree of difficulty. However, it has the following disadvantages: the medicament is injected through the injector during sputum suction, two hands of a user are required to be operated together, the user is not convenient to operate and use, the injected cooling medicament and the hairbrush are stirred, the throat of the child is easily irritated, the child is easily choked, the inserted suction head is easily damaged, and certain potential safety hazards exist.
