| description | Method and apparatus (10) for detecting contaminants, including emboli, in a fluid sample prior to sample testing, wherein fluid density sensors (52F and 52R) are arranged on opposite sides of a fluid segmenting valve (48) to provide electrical signals indicative of the degree of optical opacity of the fluid flowing through the sensors. The derived signals are compared against a diluent reference level signal to provide resultant signal outputs indicating to an operator or a monitoring device the presence or absence of emboli or other contaminants within the segmented portion of the fluid.
Procédé et dispositif (10) de détection de corps étrangers, y compris les embolus, dans un échantillon de sang avant son analyse. Des capteurs de densité du fluide (52F et 52R) sont disposés sur les côtés opposés d'une soupape (48) divisant le fluide en portions, pour produire des signaux électriques indiquant le degré d'opacité optique du fluide s'écoulant à travers les capteurs. Les signaux dérivés sont comparés avec un signal de niveau de référence du diluant pour produire des signaux de sortie indiquant à un opérateur ou à un appareil de contrôle la présence ou l'absence d'embolus ou d'autres corps étrangers dans la portion de fluide considérée. |
