CA 2228737

The invention features an analysing device (1) comprising a body (2) in which are arranged or provided: an intake aperture (3) for a starting liquid sample, a liquid flow circuit (5) comprising at least one operating cell (6) for a processed liquid sample, obtained from all or part of the original sample, communicating with the said intake aperture (3), the said flow circuit defining, in at least two dimensions of the card, one determined geometric line, such that any alteration in the card orientation in a three-dimensional reference frame, causes the liquid to flow under gravity only, from one part of the said circuit to another,for instance from one side or another of the operating cell, (6) characterised in that, the flow circuit (5) is continuous, and looped on itself between the said aperture (3) and the said operating cell (6).

Dispositif d'analyse (1) comprenant un corps (2) dans lequel sont disposés ou ménagés: un orifice (3) d'introduction d'un échantillon liquide de départ; un circuit (5) de circulation de liquide, comprenant au moins une enceinte opératoire (6) pour un échantillon liquide traité, obtenu avec tout ou partie de l'échantillon de départ, communiquant avec ledit orifice d'introduction (3), ledit circuit de circulation décrivant, dans au moins deux dimensions de la carte, une ligne géométrique déterminée, en sorte que tout changement d'orientation de la carte dans un référentiel tridimensionnel, comportant une dimension verticale de référence, fait circuler le liquide par gravité uniquement, d'une section à une autre dudit circuit, par exemple d'un côté ou de l'autre avec l'enceinte opératoire (6); caractérisé en ce que, le circuit (5) de circulation est continu et bouclé sur lui-même entre ledit orifice d'introduction (3) et ladite enceinte opératoire (6).
