Abstract

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.

Claims (37)

1 . An autotransfusion system for separating fluid constituents of a fluid, the autotransfusion system comprising:

a housing;

a rotatable drive member positioned within the housing, the rotatable drive member configured to be rotated about a longitudinal axis of the rotatable drive member, the rotatable drive member including an interior surface defining a receptacle of the rotatable drive member; and

a centrifuge bowl removably positionable in the receptacle of the rotatable drive member, the centrifuge bowl comprising an exterior wall defining an exterior surface,

at least one of the interior surface of the rotatable drive member and the exterior surface of the centrifuge bowl tapering upwardly to a larger diameter;

wherein the exterior surface of the centrifuge bowl is adapted to frictionally engage the interior surface of the rotatable drive member to rotate the centrifuge bowl about the longitudinal axis by the rotatable drive member when inserted into the receptacle.

2 . The autotransfusion system of claim 1 , further comprising:

a disposable fluid line organizer adapted to operatively couple to the centrifuge bowl.

3 . The autotransfusion system of claim 2 , the disposable fluid line organizer including a plurality of fluid lines in fluid communication with an inlet of the centrifuge bowl.

4 . The autotransfusion system of claim 3 , further comprising a manifold positioned between the plurality of fluid lines and the inlet.

5 . The autotransfusion system of claim 1 , wherein an upper portion of the interior surface of the rotatable drive member tapers upward to a larger diameter.

6 . The autotransfusion system of claim 5 , wherein the exterior surface of the centrifuge bowl tapers upwardly to a larger diameter.

7 . The autotransfusion system of claim 1 , wherein the interior surface of the rotatable drive member includes a tapered region juxtaposed with a tapered region of the exterior surface of the centrifuge bowl when positioned in the receptacle.

8 . The autotransfusion system of claim 1 , wherein the receptacle of the rotatable drive member is configured to receive any one of a plurality of different sized centrifuge bowls.

9 . The autotransfusion system of claim 8 , wherein each of the plurality of different sized centrifuge bowls has a different capacity.

10 . An autotransfusion system for separating fluid constituents of a fluid, the autotransfusion system comprising:

a housing;

a centrifuge bowl removably positionable in the receptacle of the rotatable drive member, the centrifuge bowl comprising an exterior wall defining an exterior surface,

the interior surface of the rotatable drive member having a tapered portion tapering upwardly to a larger diameter; and

the exterior surface of the centrifuge bowl having a tapered portion tapering upwardly to a larger diameter;

wherein the tapered portion of the exterior surface of the centrifuge bowl is juxtaposed with the tapered portion of the interior surface of the rotatable drive member when the centrifuge bowl is inserted into the receptacle.

11 . The autotransfusion system of claim 10 , further comprising:

a disposable fluid line organizer adapted to operatively couple to the centrifuge bowl.

12 . The autotransfusion system of claim 11 , the disposable fluid line organizer including a plurality of fluid lines in fluid communication with an inlet of the centrifuge bowl.

13 . The autotransfusion system of claim 12 , further comprising a manifold positioned between the plurality of fluid lines and the inlet.

14 . The autotransfusion system of claim 10 , wherein the receptacle of the rotatable drive member is configured to receive any one of a plurality of different sized centrifuge bowls.

15 . The autotransfusion system of claim 14 , wherein each of the plurality of different sized centrifuge bowls has a different capacity.

16 . An autotransfusion system for separating fluid constituents of a fluid, the autotransfusion system comprising:

a housing;

a plurality of centrifuge bowls, each one of the plurality of centrifuge bowls having an exterior surface having a tapered portion tapering upwardly to a larger diameter, each one of the plurality of centrifuge bowls having a different capacity; and

wherein the receptacle of the rotatable drive member is configured to receive any one of the plurality of centrifuge bowls with the tapered portion of the exterior surface of the centrifuge bowl juxtaposed with the interior surface of the rotatable drive member when inserted therein.

17 . The autotransfusion system of claim 16 , wherein the interior surface of the rotatable drive member as a tapered portion tapering upwardly to a larger diameter.

18 . The autotransfusion system of claim 16 , further comprising:

a disposable fluid line organizer adapted to operatively couple to the centrifuge bowl.

19 . The autotransfusion system of claim 18 , the disposable fluid line organizer including a plurality of fluid lines in fluid communication with an inlet of the centrifuge bowl.
