摘要:
A drive assembly for a centrifugal processing system is provided for rotating the yoke assembly (36) about a first axis at a first angular velocity and rotating the chamber assembly (30) coaxially with the yoke assembly at a second angular velocity A drive motor (60) is provided for rotating the yoke assembly at the first angular velocity A stationary gear (70 is mounted coaxially with the yoke assembly, with a drive linkage (72) comprising a shaft (74) secured to the yoke assembly so as to be rotatable therewith. The shaft is operatively connected on its first end to the stationary gear (70), so that the shaft rotates about its axis as the yoke assembly (36) rotates relative to the stationary gear. The shaft (74) is rotatably connected on its second end to the chamber assembly (30), so that when the shaft is rotated, the shaft rotates the chamber assembly. Preferably, the yoke assembly (36) comprises a first arm (38) and a second arm (40), with the chamber assembly (30) being rotatably secured to the first arm and the first arm being pivotably connected to the second arm, and the shaft (74) being flexible.

An irradiation device includes a fluid treatment chamber configured to receive a biological fluid container, the fluid treatment chamber having opposing first and second sides, at least one light source disposed adjacent at least one of the first and second sides of the fluid treatment chamber, and an overflow reservoir in fluid communication with the fluid treatment chamber to receive fluid leaking from the biological fluid container. The device also includes a non-contact sensor disposed adjacent the overflow reservoir and configured to generate a signal according to leaked fluid in the overflow reservoir, an indicator, and a controller coupled to the at least one light source, the non-contact sensor and the indicator, the controller configured to activate the indicator upon receipt of the signal from the sensor and to deactivate the at least one light source subsequent to receipt of the signal from the sensor.
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 (156a, 156b), 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 (156a) configured to engage the umbilicus at a first length between the first and second ends and a second traction feature (156b) configured to engage the umbilicus at a second length between the first and second ends.
