Abstract

A gas delivery tube 4180, such as for delivering the gas to a CPAP mask, can be stretched and bent with minimal reaction force so as not to disturb the position of the mask on the patient’s face during movement. The tube has a helical coil skeleton 4174 of thermoplastic material and a web 4172 of thermoplastic plastic material extending between the coil sections. The web includes a fold defined by at least one fold line 4186 that runs around the tube parallel to the coil to form a sort of bellows in the tube. When the tube is in the neutral state, neither stretched out (expanded) nor compressed, the diameter of the tube measured across the fold line DF is the same as the diameter of the tube DC across the coil, in other words a straight edge laid along the outside of and parallel the axis of the tube in the neutral state would touch the outside points of the coils and points on the fold lines of the web between the coils. As the web extends toward the fold line the slope angle increases from each of the coil sections to the vertex of the fold line, that is, the fold line is at a cusp of the material of the web extending from adjacent coil sections.
