Title (EN) AUTOMATED MICROBIOLOGICAL TESTING APPARATUS AND METHODS THEREFOR
(FR) APPAREIL ET PROCEDES D'ESSAI MICROBIOLOGIQUE AUTOMATISE
Abstract:
(EN) A diagnostic microbiological testing system and method for microorganism identification (ID) and antimicrobial susceptibility determinations (AST). The system includes multiple-well test panels capable of performing ID and AST testing on the same test panel. Each test panel is inoculated with reagents, broth-suspended organisms, and placed into the instrument system. The instrument system includes a rotating carousel for incubation and indexing, multiple light sources each emitting different wavelength light, precision calorimetric and fluorometric detection, barcode test panel tracking and a control processor for making determinations based on measured test data. One light source includes a plurality of LEDs arranged in a linear array. Each of the LEDs' junction currents are controllable to produce a predetermined illumination profile.
(FR) L'invention concerne un système et un procédé d'essai microbiologique de diagnostic permettant d'identifier des microorganismes (ID) et de déterminer leur sensibilité aux antimicrobiens (AST). Ledit système comprend des panneaux d'essai multi-puits permettant de réaliser les analyses ID et AST sur le même panneau d'essai. On inocules dans chaque panneau d'essai des réactifs, des organismes en suspension dans un bouillon de culture, puis on les place dans le système de mesure. Ce système de mesure comporte un carrousel rotatif servant à l'incubation et à l'indexage, plusieurs sources lumineuses émettant chacune de la lumière de longueur d'onde différente, des détecteurs fluorométriques et calorimétriques précis, un système de suivi des panneaux d'essai par détection de code barres, et une unité de commande destinée à réaliser des déterminations sur la base des données d'essai mesurées. Une des sources lumineuses comporte une pluralité de DEL disposées de façon linéaire. Chacun des courants de jonction des DEL est réglable de manière à permettre un profil d'illumination prédéterminé.
