BEARING FOR UMBILICUS OF A FLUID PROCESSING SYSTEM |
摘要 |
A fluid circuit for use with a fluid processing assembly, the fluid circuit comprising an umbilicus having a first end, a second end, an axis of rotation, and a cross-sectional circumference; a one-piece bearing secured to the umbilicus at a location between the first and second ends, the bearing having an axis of rotation and including an inner lumen which directly engages the umbilicus and includes a plurality of traction features, which bear against the umbilicus to prevent relative rotation of the bearing and the umbilicus; and the plurality of traction features comprising a first traction feature configured to engage the umbilicus at a first set of lengths between the first and second ends and a second traction feature configured to engage the umbilicus at a second set of lengths between the first and second ends. |

1. A fluid circuit for use with a fluid processing assembly, the fluid circuit comprising:
an umbilicus having a first end, a second end, an axis of rotation, and a cross-sectional circumference; a one-piece bearing secured to the umbilicus at a location between the first and second ends, the bearing having an axis of rotation and including an inner lumen which directly engages the umbilicus and includes a plurality of traction features, which bear against the umbilicus to prevent relative rotation of the bearing and the umbilicus; and wherein the plurality of traction features comprises a first traction feature which comprises a first plurality of projections disposed at a first rotational angle about the axis of rotation, the first plurality of projections defining all projections disposed on the first traction feature, and is configured to engage the umbilicus at a first set of lengths between the first and second ends, and a second traction feature which comprises a second plurality of projections disposed at a second rotational angle about the axis of rotation, the second plurality of projections defining all projections disposed on the second traction feature, and is configured to engage the umbilicus at a second set of lengths between the first and second ends. |
