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 may be a spirally wound elongate hollow body, and the other component may be an elongate structural component also spirally wound between turns of the spirally wound hollow body. The tube need not be made from distinct components, however. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be 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.本發明涉及醫療管以及製造醫療管的方法。這種管可以是由兩個或兩個以上相異的部件製成的一複合結構，該等相異部件係螺旋地纏繞以形成一長形管。例如，該等部件之一可以是一螺旋纏繞的長形中空本體，並且另一部件可以是一長形結構部件，該長形結構部件也是螺旋地纏繞在該螺旋纏繞的中空本體的多個匝之間。然而，這種管無需是由相異的部件製成。例如，由一種單一材料形成(例如，擠壓)的一長形中空本體可以進行螺旋纏繞以形成一長形管。這種長形中空本體自身可以在橫截面中具有一薄壁部分以及一相對更厚或更加剛性的加強部分。該等管可以被結合到多種醫療回路中、或可以用於其他醫療用途。
