Abstract

See full text

An airflow switching valve allowing a single ventilator to sequentially ventilate multiple patients, each patient being ventilated through a respiratory cycle. The airflow switching valve includes an outer housing, an inner housing, and a spring. Each of the outer and inner housings have a plurality of apertures that, when aligned in different positions, direct airflow to different patients. The inner housing rotates within the outer housing into different positions. The rotational movement is guided by a track of the outer housing. Extensions on the inner housing engage the track of the outer housing and translate along the track, thereby directing the movement of the inner housing between varying positions. Movement of the inner housing is initiated by either a spring force caused by the spring of the airflow switching valve or by air pressure caused by an inspiratory breath flowing into the airflow switching valve from the ventilator.
