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.

A tracheal tube having a shaft with a patient end portion adapted to extend into the body forwardly of a mounting flange and a machine end portion adapted to project rearwardly of the flange away from the patient, characterised in that the machine end portion is formed separately of the patient end portion and has a shaft provided at its machine end with a male tapered coupling adapted for mating connection with a female tapered coupling, that the machine side of the mounting flange and the patient end of the machine end portion are provided with engaging couplings of a lower profile than the mating coupling at the machine end of the machine end portion, and that the shaft of the machine end portion has its multiple recesses in its external surface arranged to increase the flexibility of the shaft of the machine end portion.
A method of assembling a tracheostomy tube including the steps of:
A tracheostomy tube having a shaft including a body with a patient end portion adapted to extend into the body forwardly of a mounting flange and a machine end portion adapted to project rearwardly of the flange away from the patient, wherein the tracheostomy tube is assembled by a method comprising the steps of:
