A diagnostic device for testing a liquid sample has a carrier for receiving at least a portion of the sample and a sample delivery means. The sample delivery means has a delivery channel that is in fluid communication with the carrier. The delivery channel has a first delivery channel surface facing a second delivery channel surface, wherein the first delivery channel surface is spaced apart from said second delivery channel surface by a distance that promotes longitudinal advancement of the sample along the delivery channel by capillary action. A deposition channel, to promote lateral dispersal of the sample across a corner, is formed either in a housing or between the housing and the carrier.
L'invention concerne un dispositif de diagnostic permettant de tester un échantillon de liquide, comprenant un substrat servant à recevoir au moins une partie de l'échantillon et un distributeur d'échantillon. Ce distributeur d'échantillon comprend un canal de distribution relié au substrat par une voie de communication liquide. Le canal de distribution comporte une première surface orientée face à une seconde surface, la première surface étant séparée de la seconde surface par un espace dont la distance permet de faire avancer l'échantillon par capillarité dans le sens de la longueur, le long du canal de distribution. Le dispositif de diagnostic comprend également un canal de dépôt permettant une dispersion latérale de l'échantillon dans un angle, formé dans un logement ou entre le logement et le substrat.
