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.

A pressure controller for an artificial respirator according to this invention includes a control valve facing a gas passage between an inspiratory gas inlet and an inspiratory gas outlet, and an elastic biasing means for elastically biasing the control valve against a valve seat. When an adjustment manipulating member moves backward, even the pivotal motion of the adjustment manipulating member does not operate an adjustment operating member. When the adjustment manipulating member is pulled out, the pivotal motion of the adjustment manipulating member operates the adjustment operating member, thereby adjusting the elastic biasing force of the elastic biasing means. This invention provides a pressure controller for an artificial respirator capable of reliably preventing unnecessary operating of the adjustment operating member although the pivoting operation of the adjustment manipulating member is simple as a whole, and there is no possibility that the adjustment manipulating member and the like are broken.
