Patent ID: 7513252

Claim:
A device ( 50 ) for scavenging tainted escape gas ( 26 ) released from the mouth of a patient ( 20 ) receiving a gaseous analgesia or anesthetic into the personal breathing space ( 32 , 35 ) of a health care provider ( 38 , 29 ) performing a medical procedure on the patient ( 20 ), said device ( 50 ) comprising: a suction arrangement ( 52 ) suspendable from a patient's nasal mask ( 40 ) used for administering gaseous analgesia or anesthetic to a patient; said suction arrangement ( 52 ) having a suction inlet ( 54 ) sufficiently positionable proximate the patient's mouth ( 24 ) so as to scavenge tainted escape gas released from the patient's mouth into the personal breathing space ( 32 , 35 ) of a health care provider ( 38 , 29 ) when the health care provider is positioned adjacent the patient ( 20 ) and an adjustable interconnection ( 58 ) mounting said suction arrangement ( 52 ) upon the patient's nasal mask ( 40 ), said adjustable interconnection ( 58 ) enabling variable positioning of said suction inlet ( 54 ) relative to the patient's mouth ( 24 ) and said suction arrangement ( 52 ) and said mounting ( 58 ) together establishing a cantilever suspension ( 60 ) of said suction inlet ( 54 ) below the nose of the patient ( 20 ); and said suction arrangement ( 52 ) further comprising an exhaust outlet ( 56 ) interconnectable with a vacuum source ( 46 ) for instituting tainted escape gas scavenging proximate the patient's face for the benefit of the health care provider by limiting exposure of the health care provider to tainted escape gas ( 26 ).
