Abstract
A flow detector including an orifice for forming a vena contracta to activate a connected pressure detector so as to trigger an alarm mechanism upon the occurrence of disconnect of the patient exhalation valve in a mechanical ventilator system. A configuration of the flow detector makes erroneous hookup of the ventilator and pressure detector hoses all but impossible.
