ABSTRACT:
A tracheal tube (20) provides an expansible channel (40) along its length. The channel normally maintains a generally concealed attitude within the trachael tube wall and adapts by expansion for the insertion of a suction catheter (60), guiding the catheter at various depths within the channel for the removal of secretions and other substances which accumulate around the tube when in use within the intubated pathway. Ports (46), located at strategic locations along the tube wall and leading to the channel, afford access to these accumulations. Among the various embodiments of the invention is a valve-like arrangement which opens the ports only when a catheter is inserted within the channel. Also, a novel means for directing and concentrating suction forces at individual ports is disclosed.
