Patent

CA 2577265

The invention relates to a microfluid system, comprising a support body (12), provided with a puncture device (14) and a semi-open microchannel (16), arranged thereon, for the capillary transport of a sample fluid from a taking position to a target position (22,24). According to the invention, a higher aspect ratio may be achieved, whereby the support body (12) is coated with an applied layer (18) which laterally defines the microchannel (16), at least in the upper region.

L'invention concerne un système microfluidique présentant un corps support (12), de préférence pourvu d'un organe de piqûre (14), ainsi qu'un microcanal semi-ouvert (16), situé sur le corps support et destiné au transport capillaire d'un échantillon liquide entre un point de prélèvement et un point cible (22, 24). L'objectif de cette invention est d'obtenir un rapport d'aspect supérieur. A cet effet, le corps support (12) est enduit d'une couche constitutive (18) délimitant latéralement le microcanal (16) au moins dans la zone supérieure et permettant le transport du liquide.
