An autotransfusion system for separating fluid constituents includes a centrifuge housing and a rotatable driving member mounted within the centrifuge housing. The rotatable driving member is configured to receive therein and rotationally engage any one of a plurality of centrifuge bowls with different heights. In some embodiments, the centrifuge bowl is integrated with a fluid line organizer to provide for easy and efficient organization of a plurality of different fluid lines incorporated into the autotransfusion system. In some embodiments, the centrifuge bowl and fluid line organizer are easily and efficiently coupled to the centrifuge housing for autotransfusion processing. After autotransfusion processing, the centrifuge bowl and fluid line organizer are easily and efficiently decoupled from the centrifuge housing and discarded.

摘要:
In one aspect, a disposable centrifuge includes a container including an interior compartment for receiving the liquid and solids. The container is capable of rotating to urge the solids toward the periphery of the interior compartment. A fixed extraction conduit may be provided for extracting at least a portion of the solids from adjacent the periphery of the interior compartment of the container. A motive device may also be provided for forming a non-contact coupling with the container, which may rotate and/or levitate the container. A relatively low, continuous flow rate (about 250 ml/min to about 500 ml/min) may also be utilized. Related methods are also disclosed.
摘要:
An optical monitoring system is provided for use with a blood processing system. The system includes a light source configured to illuminate a disposable flow circuit received in a centrifuge and a light detector configured to receive an image of the disposable flow circuit. A controller combines two or more of the images received by the light detector to generate a two-dimensional output. The output is used to control the separation of blood within the disposable flow circuit. The monitoring system may also be used to verify that the disposable flow circuit is suitable for use with the centrifuge or that the disposable flow circuit is properly aligned within the centrifuge. The monitoring system may be positioned outside of the centrifuge bucket which receives the centrifuge.

An apparatus for manipulating particles includes : a rotor rotatable at a speed about an axis, the rotor having an outer periphery and front and rear opposite sides; at least one chamber (50) mounted on the rotor, each chamber having an inlet and an outlet; an umbilical assembly rotatable about the axis; and a drive mechanism configured to rotate the umbilical assembly at about one-half the speed of the rotor. The umbilical assembly includes: a curvilinear guide tube (125) connecting to a drum at the rear side of the rotor; a flexible conduit (130) residing in the guide tube; and first and second elongate passageways (135) for each chamber extending through the conduit, wherein the first passageway is in fluid communication with the inlet of a respective chamber and the second passageway is in fluid communication with the outlet of the respective chamber. The passageways are held in a spaced-apart relationship relative to one another.
摘要:
A method and apparatus for continuous removal of submicron sized artificial oxygen carriers (rAOC) and other materials such as cancer cells and bacteria from blood and other liquids. A centrifuge rotor having a curved shape is offset on a spinning rotor base and creates contiguous areas of low to high centrifugal force depending on the distances from the axis of the rotor base. This creates a density gradient field that separates materials of different densities input to the centrifuge that exit via different outputs. A monitor detects any red blood cells (RBC) with the rAOC before they exit the centrifuge. If there are any RBC detected logic circuitry changes the speed of rotation of the rotor, and the flow rate of pumps inputting and removing separated blood and rAOC to and from the centrifuge until there are no RBC in the rAOC exiting the centrifuge.
