Abstract:
A blood processing system comprisinga separation chamber for processing blood to obtain a blood suspension containing a quantity of red blood cells, a sensing assembly outside the separation chamber to optically sense presence of red blood cells, and a fluid circuit including an umbilicus coupled to the separation chamber, a blood inlet tube extending beyond the umbilicus outside the separation chamber for conveying a flow of blood into the umbilicus, a component collection tube extending beyond the umbilicus outside the separation chamber for conveying a flow of the blood suspension from the umbilicus, and a fixture including a holder to hold the blood inlet tube and the component collection tube in an adjacent, spaced-apart relationship for handling as a bundle outside the separation chamber, the fixture being movable into releasable engagement with the sensing assembly outside the separation chamber to hold the component collection tube within the holder in a predetermined relationship with the sensing assembly so that presence of red blood cells in the component collection tube can be sensed.
