Detailed ways

The present invention will be further described below with reference to the accompanying drawings and embodiments.

1 to 3 , the air circuit system of the sputum suction device of this embodiment includes an integrated air chamber 3, an adapter 1, a filter element 2 and a liquid storage bottle 4, an integrated air chamber 3, an adapter 1 and a liquid storage bottle 4 Connected in sequence, the air outlet end of the integrated air chamber 3 is provided with multiple interfaces and connected to the negative pressure source, pressure regulating valve, sensor and other functional device ends through pipelines. It can be led out from each interface; the inlet end of the integrated air chamber 3 is provided with an adapter 1, and then connected to the liquid storage bottle 4 through the adapter 1; one end of the liquid storage bottle 4 is connected to the adapter 1 by external force extrusion, and then fixed by The buckle 5 is fixed to the main body of the suction device, and the other end of the liquid storage bottle 4 is connected to the human body through a hose.
