BLUTTRENNKAMMER MIT VORGEFORMTER BLUTDURCHFLUSSPASSAGE UND ZENTRALER VERBINDUNG ZU EXTERNEN LEITUNGEN

摘要

A blood separation chamber (18) is provided for rotation about an axis. In one implementation, the blood separation chamber (18) comprises a base (388) that includes formed walls that define a hub (120). A separation channel (126) extends about the hub (120). Flow passages (142, 144, 146) extend between the hub (120) and the separation channel (126). The hub (120) enables attachment of external tubing to convey blood to and from the separation channel (126) through the hub (120). In another implementation, the chamber (18) includes an interior channel, which includes a recess (386) that extends outside the bounds of the walls establishing separation zone. The recessed interior channel (386) permits the yields of individual blood components separated in the chamber to be maximized without cross-contamination or contamination by other components present in the chamber (18).
