CA 2611091

A biosensor strip having a low profile for reducing the volume of liquid sample needed to perform an assay. In one embodiment, the biosensor strip comprises an electrode support; an electrode arrangement on said electrode support; a cover; a sample flow channel; and an incompressible element placed between said cover and said electrode support, the incompressible element providing an opening in at least one side or in the distal end of said sample flow channel to provide at least one vent in said sample flow channel. In another embodiment, the biosensor strip comprises an electrode support; an electrode arrangement on said electrode support; a cover; and a sample flow channel, the cover having a plurality of openings formed therein, at least one of the openings in register with said sample flow channel. The invention further includes methods for preparing such a biosensor strips in a continuous manner.

Bande de biocapteur à profil bas pour réduire le volume d'échantillon liquide requis pour un essai. Selon une variante, cette bande comprend un support d'électrode, un couvercle, un canal de flux d'échantillon, et un élément incompressible assurant une ouverture sur au moins un côté ou à l'extrémité distale du canal qui permet d'établir au moins une ventilation dans le canal. Selon une autre variante, la bande comprend un support d'électrode, un système d'électrode sur ledit support, un couvercle et un canal de flux d'échantillon, le couvercle ayant une pluralité d'ouvertures et au moins l'une d'elles en alignement avec le canal de flux. Enfin, procédés d'élaboration de ce type de bande en continu.
