System rotation, therefore in lead screw driving lower nut linear movement.When nut drives telescoping tube mobile, telescoping tube pulls piston mobile.
As long as the moving distance of the accurately amount of spin of control handwheel, piston accurately controls, then the negative pressure in negative-pressure cup measures essence
The case where really control, reduction negative pressure causes harm to the human body when uncontrolled.
3, ballpoint dropping prevention can prevent nut from deviating from lead screw, guarantee that device can be used for a long time.
4, when piston moves down, and negative-pressure cup is made to form negative pressure, check valve is opened, and sputum can be in subnormal ambient from suction
Phlegm mouth enters in collecting tank.When piston moves up, exhaust valve is opened, air-flow is discharged from exhaust valve, and check valve is at this time
Closed state, sputum will not be discharged to suction sputum mouth from collecting tank.
5, oral cavity shield can facilitate sputum aspirator tube and suction sputum it is able to keep a secret it is fixed be placed on human body throat position, guarantee accurate inhale
Phlegm.Atomizer can carry out corresponding nebulae inhalation to patient.
6, the amount of sputum in collecting tank can be explicitly indicated in the graduation mark on collecting tank surface.
7, shield is avoided that the sputum in collecting tank enters in negative tube, avoids the blocking of negative tube and negative-pressure cup.
