Can a sputum aspirator flush the abdominal cavity

The sputum aspirator should not be used to flush the abdominal cavity. Since the sputum aspirator removes sputum from the respiratory tract through negative pressure, applying it to the abdominal cavity can lead to adverse effects. The response and tolerance of abdominal organs and tissues to negative pressure is different from that of the respiratory tract, which can cause unnecessary injuries or complications, and therefore the sputum aspirator can't be used to irrigate the abdominal cavity. A sputum aspirator is a medical device used to remove sputum from the respiratory tract, often consisting of a suction device, a suction tube, and a volumetric flask.
