Pump segment having connected, parallel branch line.

摘要

A blood flow conduit connects with a patient's vascular system, and segment connects the conduit with the dialyser. A portion of the conduit comprises an enlarged-diameter, tubular pump segment connected at each pump segment end with a connector. The connectors also are each connected in straight-line relation to other portions of the blood flow conduit. Typically, both connectors also each connect to a branch line in a relation parallel to the connection of the other blood flow conduit portion and the connected tubular pump segment.
