Abstract
A fluid processing assembly can be easily inserted into and removed from a rotatable centrifuge channel. The processing assembly comprises a processing container and a carrier. The processing container has flexibility and, in use, occupies the channel to receive fluids for separation in the centrifugal field. The carrier retains the processing container outside the channel in a flexed condition conforming to the channel. The carrier resists deformation of the processing container during its insertion into or removal from the channel.
Claims2
A blood processing assembly comprising
- an arcuate centrifuge channel defined between inner and outer walls which, in use, are rotated about a rotational axis to create a centrifugal field,
- an elongated processing container having a dimension measured about the rotational axis that is larger than a dimension measured along the rotational axis, the processing container also having flexibility and which, in use, occupies the arcuate centrifuge channel,
- tubing integrally connected to the processing container to convey blood from a source into the processing container to convey fluids within the arcuate centrifuge channel in a circumferential path about the rotation axis for separation in the centrifugal field, and
- a carrier secured to the processing container when outside the arcuate centrifuge channel and being shaped to maintain the processing container when outside the arcuate centrifuge channel in a rounded, flexed condition conforming to the arcuate centrifuge channel, the carrier limiting deformation of the processing container during insertion into or removal from the arcuate centrifuge channel.
