<p>An intra-tracheal sputum aspiration apparatus arranged so that air feeding to and air evacuation from trachea (13) by means of artificial respirator (12) are carried out through tracheal cannula (14) and so that in the event of sputum clogging, tube pump (16A) is operated to thereby attain discharge of sputum through suction tube (15) to the outside of the body by means of a negative pressure produced thereby. By virtue of the employment of the tube pump (16A) as a sputum aspirator (16), the intra-airway pressure by the artificial respirator (12) would have substantially no fluction even when a positive pressure is applied to the lungs. Consequently, sputum disposal can be accomplished while maintaining artificial artificial respiration, so that there can be prevented any secondary infection by infectious agents discharged from sputum collection bottle (17) into the air.</p> |
