Apparatus and method for quantifying the level of collected blood in a blood collection container of an autologous blood transfusion system

摘要

An apparatus and a method for quantifying the level of collected blood in the blood collection container (11) of an autologous blood transfusion system (20), which are capable of periodically measuring the liquid level of the collected blood in the blood collection container (11) A detection means (10, 12) for outputting a corresponding signal to the blood collection container (11) based on the output signal of the detection means, a detection means (10, 12) for outputting a corresponding signal, ) Is disclosed. The detection means comprises a plurality of light emitters (12) for emitting light arranged at different height levels (L1 to L9) on a first side of the blood collection container (11) (12) arranged at said different height levels (L1 to L9) on the second side of said blood collection container (11) facing the blood collection container (11) so that said blood collection container And a plurality of optical receivers (10) for detecting the transmitted light. For example, it is used for detection and signal analysis so as to identify and prevent the disturbing effect caused by the absorbing film on the inner surface of the blood collecting container (11), thereby increasing the reliability of signal detection and analysis Parameters of the light mechanism can be individually and dynamically adjusted.(FIG.
