摘要： A medical tube comprises a spirally wound bead forming a plurality of successive coils. Each of the plurality of successive coils has an internal diameter and an external diameter, and a spirally wound film extending between adjacent coils of the bead. The film is bonded at a first location on a surface of a first coil of the bead and at a second location on a surface of a second coil of the bead. The first coil is adjacent to the second coil and the first location and the second location are located between the internal diameters and external diameters of respective first and second adjacent coils. Together the spirally wound bead and spirally wound film form a conduit.
