US 7,008,366 B1 · Circumferentially driven continuous flow centrifuge

Abstract

A centrifuge (10) including a first rotatable mechanism (60) having a rotation axis with a fluid retentive housing (20) being coaxially mounted on the first rotatable mechanism for co-rotation therewith; a second rotatable mechanism (90) having a rotation axis with the first and second rotatable mechanisms being coaxially interconnected for co-rotation around a common axis; and fluid tubing (70) connected to the axis of the fluid retentive housing and having a distal length that extends axially outwardly from the fluid retentive housing. A support arm (50) is mounted to the second rotatable mechanism, a support tube (80) receives therethrough at least a part of the distal length of the fluid tubing, and a bearing member (82) rotatably supports the support tube in the support arm, whereby upon rotation of the first and second rotatable mechanisms, the fluid tubing is free to one of rotate with and rotate relative to the support tube.

Dependent claims

A multi-lumen rope comprising a plurality of elongated tubes for delivering one or more fluids between a first fluid containing mechanism and a fluid receiving rotatably driven rotor, one end of the rope being attached to the center of the driven rotor, the other end of the rope being attached to the first fluid retaining mechanism, the first fluid retaining mechanism being mounted on an opposing side of the rotor and such that the point of attachment of the other end of the rope is substantially coaxial with an axis of the rotor, said elongated tubes comprising at least one tube disposed in a spiral wrap, wherein one end of the rope has a right hand twist and the other end of the rope has a left hand twist.
