Multiple seal port anesthesia adapter
View Patent ↗Disclosed is an anesthesia adapter that is suitable for the simultaneous insertion of multiple devices or instruments into the lungs during ventilation of the patient, while minimizing or eliminating gas leaks. The anesthesia adapter comprises in one embodiment a first port sized to receive a first elongate instrument; a second port sized to receive a second elongate instrument; an endotrachial tube fitting configured to be coupled to an endotrachial tube, the endotrachial tube fitting fluidly coupled to the first and second ports; and a hose fitting configured to be coupled to a ventilator hose, the hose fitting fluidly coupled to the first and second ports. The first port seals around the first elongated instrument and the second port seals around the second elongate instrument.
1. An anesthesia adapter, comprising:
an adapter body having a proximal end with an opening and a distal end with an opening, the distal end configured to be fluidly coupled to an endotracheal tube;
a cap coupled to the proximal end of the adapter, the cap forming a first port sized to receive and seal around a first elongate instrument and a second port sized to receive and seal around a second elongate instrument; and
a hose fitting having a first opening fluidly coupled to the adapter body and a second opening configured to be coupled to a ventilator hose;
wherein the first and second ports are simultaneously aligned with the opening on the proximal end of the adapter, thereby providing simultaneous access to the endotracheal tube when the adapter body is coupled to the endotracheal tube.
2. The anesthesia adapter of claim 1 , additionally comprising at least one outer valve seal member with an outer slit positioned in each of the first and second ports, wherein the outer slit in the first port is sized to receive the first elongate instrument and the outer slit in the second port is sized to receive the second elongate instrument.
3. The anesthesia adapter of claim 2 , additionally comprising at least one inner valve seal member with an inner slit positioned in each of the first and second ports, the inner slit in the first port sized to receive the first elongate instrument and the inner slit in the second port sized to receive the second elongate instrument, wherein the inner slits are oriented transverse to the outer slits.
4. The anesthesia adapter of claim 3 , wherein the inner slits are oriented at a ninety degree angle to the outer slits.
