摘要：
A suction regulator arranged to be coupled to a source of partial vacuum and a patient circuit and which is operative in four modes is disclosed. A first mode isolates the source of partial vacuum from the patient. A second mode provides continuous regulated suction to the patient. A third mode provides intermittent regulated suction to the patient. The fourth mode provides unregulated full suction to the patient. The regulator includes a movable control knob for establishing the first, second, third and fourth modes and a detent mechanism holding the control knob in the position to select the desired mode. An interlock is also provided to prevent the control knob from being accidentally moved to the position establishing the unregulated full suction mode.
