Multifunctional optical sensing assembly

摘要

An optical sensing assembly is adapted for use in association with a separation device having a separation zone in which red blood cells and plasma are separated from blood. The assembly comprises a first optical sensing unit associated with a red blood cell outlet path that removes red blood cells from the separation zone. The assembly also comprises a second optical sensing unit associated with a plasma outlet path that removes plasma from the blood separation zone. The assembly further comprises a controller coupled to the first and second optical sensing units having different selectable control functions for operating the first and second optical sensing units in at least two different sensing modes.
