ABSTRACT:
A softshell reservoir has threaded fittings, one on each side of a central axis. Venous and cardiotomy blood are mixed in a mixer which screwthreadedly engages either of these fittings so the reservoir can be positioned on the right or the left of the perfusionist without crossed lines, and with a minimum of priming volume. A threaded outlet fitting may be provided on the central axis to cooperate with threaded outlet tubing to facilitate packaging and sterilizing, as well as setup and disposal.
