摘要： Disclosed is an apparatus and method for determining the liquid level of salvaged blood in a blood collection reservoir (11) of an autologous blood transfusion system (20), comprising sensing means (10, 12) for periodically sensing the liquid level of the salvaged blood in said blood collection reservoir (11) and outputting corresponding signals, and determining means (2) for determining the liquid level of the salvaged blood in said blood collection reservoir (11) based on said output signal of said sensing means. The sensing means comprises a plurality of light emitters (12) disposed on a first side of said blood collection reservoir (11) at different height levels (L1-L9) for emitting light and a plurality of light receivers (10) disposed at said different height levels (L1-L9) on a second side of said blood collection reservoir (11) opposite to said first side for sensing light emitted by said light emitters (12) and transmitted through said blood collection reservoir (11). Parameters of the optical set-up used for detection and signal analysis may be adjusted individually and dynamically so that disturbing effects caused e.g. by absorptive films on the inner surface of the blood collection reservoir (11) may be identified and prevented to thereby enhance the reliability of signal detection and analysis.

摘要： A method for processing an initial liquid medium including cells in an initial concentration to obtain a product liquid medium including cells in a product concentration includes supplying the initial medium to a separator via a first supply system, separating the initial medium into various constituents including the product medium, extracting the product medium from the separator via a first outlet system, measuring a physical parameter related to the concentration of the cells in the initial medium using a sensor, and controlling at least one process parameter as a function of the physical parameter. During the step of separating the initial medium, a solution is supplied to the separator at a flow rate via a second supply system. The flow rate of the solution is determined based on the at least one process parameter, and is reduced when the concentration of the cells measured in the initial medium increases.
