Abstract
Disclosed herein are sterilized medical coiled tubing and process for producing the same. One process comprises: helically winding a length of the medical tubing along a mandrel such that adjacent turns of the medical tubing are in contact with each other; applying solvent where the turns of the medical tubing contact each other to produce coiled medical tubing; allowing the solvent to dry; removing the medical tubing from the mandrel after the solvent has dried; and subjecting the medical tubing to a sterilization process using ethylene oxide with in-chamber aeration.

A process for producing a sterilized medical tubing coil, comprising:
- helically winding a length of medical tubing along a mandrel such that adjacent turns of the medical tubing are in contact with each other;
- applying solvent where the turns of the medical tubing contact each other to produce coiled medical tubing by:
- dipping a comb comprising a plurality of parallel pins into a container of the solvent such that the solvent adheres to the pins, wherein the parallel pins have the same spacing as adjacent turns of the medical tubing,
- disposing each of the parallel pins between respective turns of the medical tubing where the turns of the medical tubing contact each other, and
- removing the parallel pins from the turns of the medical tubing;
- allowing the solvent to dry such that the turns of the coiled medical tubing are connected to each other, but are separable;
- removing the medical tubing from the mandrel after the solvent has dried;
- and
- subjecting the medical tubing to a sterilization process using ethylene oxide with in-chamber aeration.
An apparatus for producing a medical tubing coil, comprising:
- a mandrel configured to helically wind a length of the medical tubing along the mandrel such that adjacent turns of the medical tubing are in contact with each other;
- and
- a comb comprising a plurality of parallel pins configured to apply solvent where the turns of the medical tubing contact each other to produce coiled medical tubing, wherein the parallel pins have the same spacing as adjacent turns of the medical tubing;
- wherein the solvent is allowed to dry before removing the medical tubing from the mandrel such that the turns of the coiled medical tubing are connected to each other, but are separable;
- and
- wherein the coiled medical tubing is subjected to a sterilization process using ethylene oxide with in-chamber aeration.
