Abstract
A paediatric tracheostomy tube is provided in two parts. One part is a patient end portion (13) having a silicone shaft (10) arranged to locate in the trachea. The machine end is formed with a mounting flange (20) adapted to lie against the neck and has a low profile coupling (21) on its machine side. The other part is a machine end portion (23) having a flexible, corrugated shaft (10′) of polypropylene with a low profile coupling (26) at its patient end adapted to engage the coupling (21) on the flange as a twist fit. The machine end of the machine end portion (23) has a tapered male coupling (25) adapted to fit with a female coupling on a breathing tube, the male coupling having a larger profile than the coupling (26) on the patient end of the machine end portion (23) and the coupling (21) on the flange.
