Ultra thin walled wire reinforced endotracheal tubing

摘要

An ultra thin walled wire reinforced endotracheal tubing includes a thin walled tubing comprising a polymeric material having a spring material incorporated therewith. Utilization of the spring wire material in combination with polymeric material results in a reduced wall thickness which results in a significant decrease in resistance to air flow through the endotracheal tubing. The endotracheal tubing of the present invention is made by depositing a dissolvable polymeric material on a rotating mandrel in successive layers. A spring material is also applied around the mandrel to produce the ultra thin walled wire reinforced endotracheal tubing. By controlling the rate of deposition of polymeric material along the length of the mandrel, different wall thicknesses of tubing may be achieved.
