Breathing circuit adapter
First Claim
1. An adapter for removably coupling a patient breathing circuit to a ventilator, said adapter comprising:
- an inhalation conduit having a first end for coupling said adapter to the ventilator and a second end for coupling said adapter to the patient breathing circuit;
an exhalation conduit having a first end for coupling said adapter to the patient breathing circuit and a discharge conduit, said discharge conduit transversely oriented to said inhalation conduit;
an exhaust port communicating with said discharge conduit for releasing breathed gas from same;
a valve selectively opening and closing said discharge conduit to release gas from same; and
a base comprising means for releasably coupling said adapter to the ventilator.

Abstract
An adapter couples a patient'"'"'s breathing circuit to a ventilator. In the preferred embodiment, the adapter comprises an inhalation conduit having a first end for coupling the adapter to the ventilator and a second end for coupling the adapter to the patient breathing circuit; an exhalation conduit having a first end for coupling the adapter to the patient breathing circuit and a discharge conduit, the discharge conduit transversely oriented to the inhalation conduit; an exhaust port communicating with the discharge conduit for releasing breathed gas from same; a valve selectively opening and closing the discharge conduit to release gas from same; and a base comprising means for releasably coupling the adapter to the ventilator.

11. An adapter for removably coupling a patient breathing circuit to a ventilator, said adapter comprising:
-
an inhalation conduit having a first end for coupling said adapter to the ventilator and a second end for coupling said adapter to the patient breathing circuit;
an exhalation conduit having a first end for coupling said adapter to the patient breathing circuit and a discharge conduit, said discharge conduit transversely oriented to said inhalation conduit;
a valve selectively opening and closing said discharge conduit to release breathed gas from same;
an exhaust port through which breathed gas from said discharge conduit is released; and
a base for coupling said adapter to said ventilator, said base comprising a lip and a keyhole, wherein said lip is received by a ledge on the ventilator and said keyhole is received by a slot in the ventilator, and wherein upon insertion of said keyhole into said slot, a spring-biased bar in the ventilator is cammed open and subsequently biased closed through said keyhole to removably couple said adapter to the ventilator. - View Dependent Claims (12, 13, 14, 15)

18. An adapter for removably coupling a patient breathing circuit to a ventilator, said adapter comprising:
-
an inhalation conduit having a first end for coupling said adapter to the ventilator and a second end for coupling said adapter to the patient breathing circuit;
an exhalation conduit having a first end for coupling said adapter to the patient breathing circuit and a discharge conduit, said discharge conduit transversely oriented to said inhalation conduit, wherein said inhalation and exhalation conduits are coaxial;
a medicine delivery conduit communicating with said inhalation conduit intermediate its first and second ends, said medicine delivery conduit for receiving medicine and providing same to said inhalation conduit;
a pressure port for removably coupling a pressure monitor tube to said adapter;
a electro-mechanically actuated valve selectively opening and closing said discharge conduit to release breathed gas from same;
an exhaust port through which breathed gas from said discharge is released; and
a base for coupling said adapter to said ventilator, said base comprising a lip and a keyhole, wherein said lip is received by a ledge on the ventilator and said keyhole is received by a slot in the ventilator and wherein upon insertion of said keyhole into said slot, a spring-biased bar in the ventilator is cammed open and subsequently biased close through said keyhole to removably couple said adapter to the ventilator.
