Abstract

Disclosed herein are sterilized medical coiled tubing and process for producing the same. One process comprises: helically winding a length of medical tubing along a mandrel such that adjacent turns of the medical tubing are in contact with each other at tubing contact points; applying a UV adhesive to the tubing contact points to produce a medical coiled tubing; curing the tubing by applying UV light to the tubing contact points; and removing the medical tubing from the mandrel after the solvent has dried.

Claims (17)

1. A method, 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 at tubing contact points;

applying a UV adhesive to the tubing contact points to produce a medical coiled tubing by

dipping a comb comprising a plurality of parallel pins into a container of the UV adhesive such that the UV adhesive adheres to the pins, wherein the parallel pins have the same spacing as adjacent turns of the medical tubing,

disposing each of the pins between respective turns of the medical tubing where the turns of the medical tubing contact each other, and

removing the pins from the turns of the medical tubing; and

curing the tubing by applying UV light to the tubing contact points.

2. The method of claim 1 , further comprising:

subjecting the medical tubing to a sterilization process using ethylene oxide with in-chamber aeration.

3. The method of claim 1 , wherein said applying the UV adhesive to the tubing contact points comprises:

applying the UV adhesive at multiple points between each pair of adjacent turns of the medical tubing.

4. The method of claim 1 , further comprising:

removing the medical tubing from the mandrel.

5. The method of claim 4 , further comprising:

equipping and packaging the medical tubing.
