MULTILUMEN CONNECTOR TO MULTIPLE INDIVIDUAL TUBING

摘要

An umbilicus for use in an umbilicus-drive fluid processing centrifuge system is disclosed, together with a method of making it and a fluid flow circuit including such umbilicus. The umbilicus includes an elongated umbilicus body, a first end fitting defining an interior cavity, an adapter received within the interior cavity and having at least one port extension extending into a fluid transmitting lumen of the umbilicus body, the adapter and end fitting including interfering surfaces to enhance torque resistance therebetween.

1. An umbilicus for use in an umbilicus-driven fluid processing system, comprising:
an elongated umbilicus body including first and second ends, wherein the umbilicus body defines at least one fluid-transmitting lumen extending between the first and second ends; a first end fitting defining an interior cavity and including an elongated bore communicating with the cavity; the first end of the umbilicus body extending into the bore and being fixedly attached to the fitting; the interior cavity of the first end fitting includes a flared portion; an adapter including a tapered portion received within the interior cavity of the first end fitting with the tapered portion received within the flared portion of the interior cavity, and having at least one port extension extending into the at least one fluid transmitting lumen of the umbilicus body; the adapter including a lumen extending through the port extension and communicating between the at least one umbilicus lumen and a tubing port defined in the adapter and configured for attachment to an individual flow tube; and the adapter and end fitting including interfering surfaces to enhance torque resistance therebetween.
