REINIGUNGSSYSTEM FUER EIN BLUTLEITUNGSNETZ.

摘要

Method and apparatus for purging air from a tubing network finds utility as a component part of a blood constituent processing system (10). Collection and returned needles (12, 14) of a disposable tubing network are initially contained within a common antiseptic enclosure (16). A purge fluid (e.g., saline solution) may then be introduced into the interior chamber of the enclosure (16) via one of the needles (12, 14) and withdrawn from the interior chamber of the enclosure (16) via the other of the needles (12, 14). Air entrained in the tubing network may thus be trapped within the common enclosure (16) itself and/or vented therefrom via a one-way valve and hydrophobic microbe filter (72) and/or the entrained air pockets may be encouraged to flow to a separate suitable air trap location (50) of the tubing network whereby the network is purged of air.
