Patent ID: 6935338

Claim:
An airway adaptor comprising: (a) a tubular body having a first gas flow passage defined therein and a longitudinal axis extending along the first gas flow passage; and (b) a protrusion extending from an interior wall of the tubular body into the gas flow passage, wherein the protrusion includes: (1) a distal end portion spaced apart from the interior wall of the tubular body, and wherein at least a first portion of the distal end portion is defined in a first plane that is generally parallel to the longitudinal axis, and (2) a second gas flow passage defined through the protrusion having an inlet defined in the first portion of the distal end portion, and an outlet at an exterior portion of the tubular body; and (c) a pair of sidewalls extending from the distal end portion of the protrusion such that each sidewall is defined in a second plane is generally parallel to the longitudinal axis, wherein the inlet of the second gas flow passage is disposed between the pair of sidewalls, and wherein the first plane is generally perpendicular to the second plane.
