Devices for potting a filter for blood processing

A device for potting a filter, comprising:

• a filter housing configured to hold filter membrane fibers extending along a length thereof between first and second ends of said filter housing;
• said filter housing having at least one first opening at said first end and at least one second opening at said second end, said at least one first opening and said at least one second opening communicating with an interior of said filter housing with a flow guide for guiding the flow of potting material;
• said flow guide having a ridge connected alone a length of said filter housing such that said flow guide has the shape of an open trough;
• said flow guide being configured such that potting material flows toward said holes when said flow guide is temporarily covered to enclose it by a cap and when said filter housing and said cap are spun about an axis perpendicular to a longitudinal axis of said filter housing, whereby when filter fibers are held in said filter housing and potting material so caused to flow, the amount of potting material settling toward said first and second ends is maximized.

A device for potting a filter, comprising:

• means for supporting filter fibers;
• means for containing potting material at ends of said means for supporting;
• means for guiding permanently attached to said means for supporting a fluid effective to seal said filter fibers when said fluid is hardened;
• means for temporarily enclosing an open length of said means for guiding,
• said means for guiding including means for conveying said fluid toward said means for containing such that said fluid is distributed evenly between said ends when said means for supporting, said means for guiding, and said means for temporarily enclosing are spun about an axis of said means for supporting.

A device for potting a filter, comprising:

• a housing configured to hold a filter bundle, said housing having an elongated shape with a longitudinal axis;
• said housing having an elongated open trough on a side thereof, said trough having a longitudinal axis generally parallel to said housing longitudinal axis;
• said housing having at least one port communicating an interior of said housing with an exterior thereof;
• said open trough being defined by a ridge having an edge;
• said edge being shaped to form a seal with a trough cap such that said open trough may be enclosed.
