Shape flowmeter 5 is started to work, and the signal wire of four pressure sensors in the annular flow gauge 5 is connect with controller, is controlled
The pressure value of four pressure sensors of device real-time reception processed, when sucking sputum unobstructed in sputum aspirator tube, four sensor detections
The pressure value arrived is equal in magnitude, illustrates that sputum is relatively more, when the pressure sensor of wherein one or two is significantly less than its overbottom pressure
When force snesor, illustrate that sputum amount is few, when four pressure sensors have not detected that liquid flows into, controller according to
Real-time reception to pressure sensor pressure signal and preset time threshold be compared judgement, it is pre- in more than controller
If time threshold when, when the pressure sensor in annular flow gauge 5 has also been not detected sputum and flows into, controller sends corresponding
Control command to solenoid valve, open solenoid valve 3, the medicine that drips from fluid injection pipe device 2 automatically drop or dilution, dilute sputum
Concentration, to help sputum is sucked out.
The beneficial effects of the invention are as follows：Can during suction sputum to the flow of sputum into monitoring, control solenoid valve
It opens, liquid or the difficult sputum being sucked out of flushing liquor dilution is added, there is automation, save the time, improve the safety etc. of suction sputum
Feature.
