Method for making sterile connections between fluid conduit tubes

A method for invading a first sterile compressible rubber tubing segment, through the bore of which sterile fluid flows, so as to establish therewith sterile fluid flow with a second compressible rubber tubing segment, comprising the steps of:

• (a) at two spaced-apart areas along the length of said first sterile tubing segment, compressing the tubing to an extent sufficient to close the tubing bore at each of said areas and thereby isolate the length of tubing between said areas;
• (b) thereafter cutting said isolated length of tubing to provide a first tubing end segment;
• (c) providing a second compressible rubber tubing segment having a second tubing end segment compressibly isolated from a sterile segment thereof;
• (d) arranging within the bore of said first tubing end segment one of the respective two ends of a hollow conductive metal tube;
• (e) arranging within the bore of said second tubing end segment the other end of said hollow conductive metal tube, thereby connecting said first sterile tubing segment and said second tubing segment;
• (f) arranging at least a portion of said connected first and second tubing segments, including said hollow conductive metal tube, within the field of a primary induction work coil;
• (g) supplying an alternating current to said work coil so as to cause said hollow conductive metal tube to be inductively heated to sterilize it and for sterilizing the bore portion of said first and second tubing end segments, thereby forming a sterile connection;
• and
• (h) thereafter removing the compression on the first sterile tubing segment and the second tubing segment so as to establish fluid communication therebetween through said sterile connection.
