Patent

CA 2300090

A device and method for verifying correct performance of an optical clinical assay system is provided. The device consists of a heated support stage (27), containing an optical window (30) through which light (22) emitted from a light source (21) can pass. Additionally, the device includes an. optical shutter (12) with a backing (13) and a circuit board (10). An algorithm or method controls the rate in which an opaque optical reference is revealed to the detection apparatus and the algorithm or method is selected to simulate the reaction rates of one or more levels of clinical analytes reacting with a test reagent.

L'invention porte sur un dispositif et un procédé permettant de vérifier le bon fonctionnement d'un système d'essai clinique optique. Le dispositif consiste en une platine (27) support chauffante munie d'une fenêtre (30) optique à travers laquelle passe la lumière (22) émise par une source lumineuse (21); le dispositif comporte de plus un obturateur (12) optique comportant un fond (13) et une plaquette de circuit (10). Un algorithme ou un procédé commande la fréquence à laquelle une référence optique opaque est révélée à l'appareil optique, l'algorithme ou le procédé étant choisis pour simuler la fréquence des réactions d'un ou plusieurs niveaux d'analytes cliniques réagissant avec un réactif d'essai.
