ABSTRACT:
A device for triggering the inspiratory phase of a ventilator having a three-way connector with an inspiratory conduit and an expiratory conduit, each communicating with the ventilator and with a patient communicating conduit. A valve arrangement associated with both the expiratory and inspiratory conduits are automatically operated by a patient attempting to breathe, such that the patient is only exposed to the air volume in the three-way connector and not to the greater air volume of the ventilator and its connected tubing.
