A kind of sputum aspirator, including reservoir and safety flack, reservoir are connected to safety flack by intermediate conductor；On reservoir Attraction pipe fitting is installed；Safety flack is communicated with aspiration pump by connecting tube, and connecting tube one end is air inlet, and the other end is The air inlet of venthole, connecting tube is connected to safety flack；Pressure gauge is installed between safety flack and aspiration pump, is pacified on pressure gauge Equipped with pressure regulating switch；Aspiration pump upper end is equipped with sound-muffling box.

It is further to improve, it is equipped with one floating ball of floating ball structure in the air inlet position, when liquid level reaches early warning in reservoir Liquid level, floating ball structure floating ball, which is swum on liquid level, blocks attraction pipe fitting.

Further to improve, the floating ball structure includes floating ball and the floating ball cap with floating ball cooperation, floating ball cap and suction tube Fittings.

Further to improve, the extreme negative pressure value in the reservoir is defaulted as >=0.075MPa.

Further to improve, the aspiration pump is electrically connected with pumping pump circuit, the pumping pump circuit include first switch, Second switch and protective tube, the first switch movable end are electrically connected aspiration pump one end, and the first switch fixing end connects 12V The anode of direct current, the movable end of the other end connection second switch of the aspiration pump, the fixing end connection of the second switch One end of protective tube, the cathode of the other end connection 12V DC electricity of the protective tube.

Further to improve, the reservoir outer surface is coated with scale.

As can be seen from the above technical solutions, the utility model embodiment has the advantage that

Entire sputum aspirator is in confined space by the utility model, by extracting air in reservoir, suction sputum in aspiration pump It is equipped with pressure gauge and pressure regulating switch in device, can be adjusted at any time with pressure value in real time reaction reservoir, leads to simultaneously It crosses safety flack to be buffered, aspiration pump suction suddenly change can be prevented, air in extraction reservoir that can be light and slow, suction sputum operation It is convenient, be conducive to preferably to old man or patient phlegm-suction.
