Abstract
A medical tube transports gases to and/or from a patient. The medical tube includes a bead wrapped around a longitudinal axis of the medical tube. The bead forms a first portion of a lumen wall of the medical tube. The medical tube also includes a film wrapped around the longitudinal axis of the medical tube. A first portion of the film overlies the bead, and a second portion of the film forms a second portion of the lumen wall. The lumen wall, formed by the bead and the second portion of the film forms a substantially smooth bore. The medical tube can be reusable or reprocessable.
Claims19
A medical tube for transporting gases, the medical tube comprising:
- a bead wrapped around a longitudinal axis of the medical tube, the bead forming a first portion of a lumen wall of the medical tube;
- and
- a film wrapped around the longitudinal axis of the medical tube, a first portion of the film overlying the bead and a second portion of the film forming a second portion of the lumen wall;
- wherein the lumen wall, formed by a flat surface of the bead and the second portion of the film, comprises a substantially smooth bore, such that the flat surface of the bead and the second portion of the film are aligned when the medical tube is straight along the longitudinal axis;
- wherein one or more wires is disposed within the bead, the one or more wires being a heating wire, a sensing wire and/or a ground wire;
- wherein the bead imparts structural support, reinforcement and/or resistance to crushing to portions of the medical tube comprising film;
- and
- wherein the film comprises a plurality of layers, wherein a first layer of the plurality of layers overlaps a second layer of the plurality of layers over an outer surface of the bead to form an overlapping portion.
