A closed system suction catheter assembly has a suction catheter (23) with its rear end connected to a machine end fitting (29). The opposite end of the catheter has a soft tip (27) and extends through a wiper seal (120) at the rear end of a flushing chamber (21) within a patient end fitting (20). A flexible envelope (28) extends between the machine end and patient end fittings (29 and 20). A connector (4, 4') has three ports, a first (41) of which is fitted on the patient end fitting (20), a second (42, 42') of which is fitted to the connector (46) at the machine end of a paediatric tracheal tube (2), and the third (43) of which extends at an acute angle to the first port. The wall of the connector (4, 4') is thickened to form an annular portion of semicircular section extending around the connector providing a magnifying viewing window (50) adjacent the forward end of the first port (41). The window (50) enables coloured distance markers (51) along the suction catheter (23) to be viewed as the catheter is extended through the connector (4, 4'). |
