Definitions

  • a cavity of a sample carrier designed to hold blood samples and test reagents is positioned in a measuring position, the cavity in the measuring position is illuminated and scanned two-dimensionally by means of a color image sensor with color-selective generation of analog image signals,
  • the image data can optionally be displayed on a display unit as a preferably enlarged color image of the detected cavity in connection with evaluation results. It is also provided that the image data can be stored on a storage device in association with patient data.
  • the color image pickup 10 is formed by a video camera 32 which has a CCD image sensor 34 operating in the three basic color levels red, green, blue (R, G, B).
  • Imaging optics 36 are arranged in front of the CCD image sensor 34 and enable the sensor surface to be focused on the facing inner wall of the cavity 12 in the measuring position.
  • An interchangeable lens 40 which can be actuated by means of an actuator 38, serves to interpose various optical elements in the beam path Bring cavity 12 and color image pickup 10.
  • a measuring light filter 42 of the exchangeable optics 40 transmits the measuring light emanating from the cavity 12 in the visible wavelength range and blocks in the UV and IR ranges.

Abstract

L'invention concerne un dispositif et un procédé d'analyse de sang pour établir un sérodiagnostic. L'invention vise à permettre d'effectuer un test, et d'évaluer les résultats de ce dernier, de manière objective et fiable. A cet effet, l'invention est caractérisée par les éléments suivants: un support d'échantillons (14) présentant au moins une cavité (12) destinée à recevoir les échantillons de sang (18) et des réactifs de dépistage; une source lumineuse (24) servant à éclairer la cavité (12) à analyser; un dispositif d'acquisition d'image couleur (10) servant au balayage en deux dimensions de la cavité à analyser (12) et servant à produire des signaux d'image, associés respectivement à une couleur; un convertisseur analogique/numérique (50) pour convertir les signaux d'image en données d'image numériques associées à des points d'image et divisées en couleurs fondamentales, sous forme de points d'image; une unité de traitement d'images (16) traitant les données d'image, servant à la reproduction et/ou à la classification de motifs de réaction de l'échantillon de sang (18), formés dans la cavité (12).
