Abstract: A blood separation apparatus comprises a blood separation chamber (18) having a base (388) including formed walls (122, 124) that define an annular separation channel (126), an interior wall (136) that extends across the separation channel (126) to define a terminus, an inlet passage (146) on one side of the terminus that conveys blood into the separation channel (126) in a flow path for separation into blood component, an outlet passage (142) on another side of the terminus that conveys the blood component from the flow path and a mechanism to rotate the blood separation chamber (18) about an axis in direction of blood flow in the flow path from the inlet passage (146) toward the outlet passage (142).

Abstract: Red blood cell sensing systems rely upon straightforward measurement geometries. The systems are based around a sensing station (332) having incident light source containing optical sensor s (334) and (336) and blood collection tubes (290), (292) and (294). The systems hold the blood collection tubes (290), (292) and (294 ) a predetermined radial distance from the sensors (334) and (336), where a linear relationship exists between sensed reflected light measured by the sensor; (334) and (336) and red blood cell hematocrit in a range of at least 10 to 90. The systems make possible accurate red blood sensing without use of special optical cuvettes, mirrors, or focusing lenses. The systems also make possible the us e of standard transparent plastic tubing, without reliance upon special optical cuvettes.
