As the utility model discloses a preferred scheme, the baffle with be provided with the elastic component between the cavity, in the use, because the improper of operation for when the articulated bottom of being in of baffle and connecting pipe, the through-hole can not be sealed through the gravity of self to the baffle, and the elastic component can promote the baffle in order to seal the through-hole.

As the preferred scheme of the utility model, keeping away from of baffle one side be provided with interior wall connection's arc portion for the sputum can get into in the negative pressure ball through arc portion.

As the utility model discloses an optimal scheme, keeping away from of hose negative pressure ball one end is provided with the opening, the side of hose is provided with the side opening for can increase disposable suction sputum liquid volume, reduce the number of times of extrusion negative pressure ball, reduce work load, can be fast with the sputum suction, ensure that the patient can breathe unobstructed or can carry out artificial respiration smoothly.

As the utility model discloses an optimal scheme, be provided with the opening on the storage phlegm bag, be provided with the piston on the opening, be full of when gaseous too much in storing up the phlegm bag, the accessible is opened the piston and is emitted the gas that stores up the phlegm bag, seals the piston again and stores up the phlegm bag for can continue to inhale phlegm, avoid storing up too big fracture of phlegm bag internal pressure, make the sputum splash everywhere.

As the preferred scheme of the utility model, the hose adopts medical PVC material, store up the phlegm bag and adopt transparent material for sputum volume can be observed.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. through having connected hose and storage sputum bag on the negative pressure ball, and connect through the check valve respectively, after the hose inserts patient's oral cavity or respiratory track, through extrusion negative pressure ball, gas in the negative pressure ball passes through the check valve and gets into in the storage sputum bag, loosen the negative pressure ball, the sputum passes through in the hose gets into the negative pressure ball, extrude negative pressure ball once more, the sputum can get into in the storage sputum bag, convenient operation, do not need medical personnel through mouthful mode suction sputum to the mouth, cross infection has been avoided, and the absorption efficiency of sputum has been improved, the sputum of suction can be avoided to the storage sputum bag splashes everywhere, avoid the phenomenon that unhygienic and medical personnel are infected.
