Catheter mounts are adaptors that connect the tracheal tube to the end of the anaesthetic breathing system. Various connectors fit between the distal end and the tracheal tube. The proximal end is of standard 22 mm taper. Connectors are 15 mm in size distally, and they fit to any standardised 15/22 mm equipment.
Some incorporate a capped port for tracheobronchial suction and insertion of fibreoptic instruments.
3 general types of catheter mounts: Corrugated, Extendible, Smooth-Bore.
Can also be using integrated with a HME Filter.
