Claim 0:
1. A supraglottic airway device (300), comprising:
an elongate breathing tube (304) having an outer wall and an inner wall, and including a first open end (304a) and a second open end (304b) opposite the first end; and
a coupler assembly (302) including
a first cylindrical male end (302a) having a tube-engaging side surface (318) configured to insertably engage the first open end (304a) of the elongate breathing tube (304) so as to form an interference fit with the inner wall of the elongate breathing tube,
a second cylindrical male end (302b) configured for coupling with a medical device, and having a contaminant-blocking air pass filter (320), and
a housing having
a suction port (316) disposed in and passing through the tube-engaging side surface (318) of the first cylindrical male end (302a), and a self-closing seal (316a),
a pressure port (341), and
a ventilation port (351);

wherein a distal-most edge of the second cylindrical male end (302b) is wider than a proximal-most edge of the first cylindrical male end (302a), and the contaminant-blocking air pass filter (320) extends across an entirety of the second cylindrical male end (302b) without covering the suction port (316).
