摘要：
Medical tubes and methods of manufacturing medical tubes are disclosed, suchas in positive airway pressure (PAP),respirator, anaesthesia, ventilator, and insufflation systems. The tube may bea composite structure made of two or more distinctcomponents spirally wound to form an elongate tube. One of the components maybe a spirally wound elongate hollow body, and the othercomponent an elongate structural component spirally wound between turns of thespirally wound hollow body. Alternatively, the tubeneed not be made from distinct components. For instance, an elongate hollowbody formed (e.g., extruded) from a single material maybe spirally wound to form an elongate tube. The elongate hollow body itselfmay in transverse cross-section have a thin wall portionand a relatively thicker or more rigid reinforcement portion. The tubes can beincorporated into a variety of medical circuits or haveother medical uses.
