Reinforced tubes

A medico-surgical tube, in particular a cuffed tracheostomy tube (1, Fig. 1) including a shaft (10, Fig. 1) formed of a flexible plastics material, and a reinforcement member 25 formed as an elongate member of a more rigid plastic formed into a coil extending around the shaft. The reinforcement includes a plurality of struts 27 formed integrally with the coil extending between adjacent turns of the coil to resist displacement of the turns. The wall may be formed of silicone, with the reinforcement comprising multiple loops extending from opposite directions a part way around the shaft to leave a longitudinal gap along which a cuff inflation lumen can extend. The reinforcement may include integral spring arched struts shaped to flex and accommodate limited movement. The loops of one set 26A may be wider than loops of the other set 26B.
