Abstract

See full text

A set for conveying blood between a patient and blood treatment apparatus such as a dialyzer. The set comprises a blood flow conduit, connecting with a patient's vascular system, and means for connecting the conduit with the dialyzer. 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 substantially straight-line relation to other portions of the blood flow conduit. Typically, both connectors also each connect to a branch line in a relation substantially parallel to the connection of the other blood flow conduit portion and the connected tubular pump segment. Thus, the set is more capable of being rolled up and packaged in an automated manner, since it can be free of branching connections which connect at a substantial angle to the overall axis of the set.
