Patent

CA 2170402

A disposable electronic assay device (2) comprises a card-like housing (8) containing a sample receptor (4) for receiving a sample of body fluid containing an analyte to be determined, a sample treatment means (10) for reaction with sample fluid components to yield a physically detectable change for producing an electrical signal which correlates with the amount of analyte in the sample, a detector (20, 22) responsive to the signal, a signal processor (32) connected to the detector (20, 22) for converting the electrical signal to a digital test result output, and visually readable output means (6) connected to the signal processor means (32) for receiving and presenting the test result output.

Dispositif électronique jetable d'analyse (2) comprenant une carte support (8) où se trouve un récepteur (4) destiné à recevoir un échantillon de liquide corporel contenant un analyte à déterminer, un moyen (10) de traitement de l'échantillon devant réagir avec les constituants fluides de l'échantillon et provoquer un changement physique détectable induisant un signal électrique corrélable avec la quantité d'analyte présente dans l'échantilon, un détecteur (20, 22) réagissant au signal, un processeur de signaux (32) relié au détecteur (20, 22) et convertissant le signal électrique en un résultat sous forme numérique, et un moyen de visualisation (6) relié au processeur (32) recevant et présentant le résultat de l'analyse.
