The invention relates to a microfluidic channel (6) with shifted levels comprising a channel pillar (2a, 2b) and a channel bridge (3) which microfluidic channel (6) connects a channel (4a, 4b), situated in a first level of a base plate (1, 11) which contains a microfluidic system, with a second level of said base plate (1, 11). A longitudinal hollow with an edgeless cross-section is connected, as a channel pillar (2a, 2b), with one end, to the ending of the channel (4a, 4b) to be connected and formed in the first level of the base plate (1, 11), furthermore, the channel bridge (3) created at the second level of the base plate (1, 11) and having a cross-section fitting to the channel pillar (2a, 2b) is surrounded by a filling-up material (7) filled in subsequently, and a rounding-off is formed at the junction of the connecting end of the channel bridge (3) and the end of the channel pillar (2a, 2b) extending to the second level.
L'invention concerne un canal microfluidique (6) à niveaux décalés comprenant un pilier (2a, 2b) et un pont (3). Le canal microfluidique (6) relie un canal (4a, 4b) situé à un premier niveau d'une plaque de base (1, 11) qui contient un système microfluidique, à un second niveau de ladite plaque de base (1, 11). Un creux longitudinal à section transversale sans bord est relié, sous forme d'un pilier de canal (2a, 2b), par une extrémité, à l'extrémité du canal (4a, 4b) destiné à être relié et formé dans le premier niveau de la plaque de base (1, 11). En outre, le pont du canal (3), créé au second niveau de la plaque de base (1, 11) et ayant une section transversale s'adaptant au pilier du canal (2a, 2b), est entouré par un matériau de remplissage (7) durci par la suite, et un arrondi est formé à la jonction de l'extrémité de liaison du pont du canal (3) et de l'extrémité du pilier du canal (2a, 2b) s'étendant jusqu'au second niveau.
