摘要： A tracheostomy tube assembly includes an outer tracheal tube (1) and a removable inner cannula (20). The inner cannula (20) has a corrugated outer surface (23) but a smooth inner surface (22). At its patient end the inner cannula (20) has an integral tip (26) with a smooth outer surface that forms a close sliding fit with the inside of the outer tube (1). At its rear, machine end the inner cannula has an integral hub (30) that fits in a hub (18) on the outer tube. The smooth inner surface (22) of the inner cannula (20) allows non-turbulent gas flow along the assembly and facilitates insertion of devices along the cannula.

摘要： A cuffed tracheostomy tube has a sealing cuff 10, 10′, 100, 100′ attached to a shaft 1, 1, 1″ of the tube towards its patient end by a rear end collar 30, 55, 103 bonded with the outside of the shaft. In one embodiment the patient end collar 31, 31′ is folded unattached around the patient end face 60, 60′ of the shaft and is attached to the inside of the tube. When inflated, the cuff inflates slightly away from the patient end face to cushion the tip of the tube. In another embodiment the cuff 100 is formed integrally with the shaft 51. In a further embodiment the cuff 100′ has an integral portion 102 of a soft material that forms a patient end extension of the shaft 1″.

摘要： An inner cannula (20) for a tracheostomy tube is made by extruding tubing (41) and cutting into separate lengths or preforms (42). Each preform (42) is placed in a mould (50, 51, 52) and blow moulded to expand the preform into contact with an inner surface (53, 54) of the mould which is shaped to produce a pattern on the outside of the preform of two intersecting diagonal corrugations (211, 212) that act to strengthen the blow moulded preform against lateral forces. The inner surface of the mould may also be textured so that the blow moulded preform is given a texture (213) to reduce friction with the outer tube (1).
