Abstract

A respiratory access assembly includes a distal plate having one port and cuff and an axially aligned proximal plate including a first port and first cuff and a second port and second cuff. The distal plate is configured to move relative to the proximal plate. The respiratory access assembly includes an actuator, which has a plurality of predetermined positions. The actuator includes a blocking portion that controls the movement of the plates. The blocking portion moves slidably within an O-ring that prevents loss of pressure from the artificial airway system. The O-ring may be molded in place using an injection molding process, thus ensuring good adhesion to the disk.
