  • Maintaining the dimensional integrity of thermoplastic tubing ends for receiving a luer
    Patent number: 4379472
    Abstract: An end of thermoplastic tubing which is exposed to a temperature capable of causing dimensional distortion of the tubing end may be maintained by enclosing the tubing end with a tubular end cap. The end cap defines an inner member projecting axially into the bore of the tubing end, with the inner member defining an outer diameter of essentially the diameter of the bore of the tubing end, so that the dimensional integrity of the tubing end is maintained during the heating step to thereafter sealingly receive a luer.
    Type: Grant
