MEDICAL TUBES AND METHODS OF MANUFACTURE

Abstract The disclosure relates to medical tubes and methods of manufacturing medical tubes. The tube may be a composite structure made of two or more distinct components that are spirally wound to form an elongate tube. For example, one of the components maybe a spirally wound elongate hollow body, and the other component maybe an elongate structural component alsospirally wound between turns of the spirally wound hollow body. The tube does not need to be made from distinct components. For instance, an elongate hollow body formed (e.g. extruded) from a single material maybe spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or may be employed for other medical uses.
