Abstract

A ventilation tube unit (2), for connection to a medical ventilator, includes an outer tube (4) with a tubular connection device (18) with a jacket-side branch (24, 28), for connecting a medical unit such as a water trap, arranged between a first outer tube part (20) and a second outer tube part (22). An inner line (6) is arranged within and extends with the outer tube (4) between two port connectors (8). Each outer tube part (20, 22) includes a variable-length outer tube part that can be varied between a compressed state and an expanded state. The connection device (18) is displaceable in the longitudinal direction (A) relative to the inner line (6) by a compression of one outer tube part (20) and a corresponding expansion of the other outer tube part (22). A ventilation system with at least one such ventilation tube unit is also provided.
