ABSTRACT:
A tracheostomy tube assembly including an outer cannula having a hollow tube-shaped body with an interior passage therethrough, an open distal end, and a proximal end zone including an open proximal end; an inner cannula having a hollow tube-shaped body having an air flow channel therethrough, a first open end and an opposite second end zone including an open second end, the inner cannula being structured for fitted, sliding receipt within the inner passage of the outer cannula such that the second end zone protrudes from the open proximal end of the outer cannula. A circuit connector head includes an airflow passage therethrough extending between an open bottom end adapted for vertical interconnection with the ventilator circuit of a ventilator system and a main face substantially perpendicular to the open bottom with an open port therethrough, the open port being structured for airtight attachment to the proximal end zone of the outer cannula such that the air flow passage is disposed in fluid flow communication with the air flow channel of the inner cannula and the ventilator circuit.
