Patent

CA 2432452

A glucose sensor in the form of a skin patch (2) has a microneedle (4) which painlessly penetrates the skin to draw out interstitial fluid. The interstitial fluid passes to a common entrance port (7). A series of microchannels (8) is provided on the skin patch. The fluid drawn onto the patch is selectively switched between a number of microchannels (8) by means of electro-osmotic pumps (10) and hydrophobic gates (12). Each microchannel (8) has an electrochemical detector (11) for sensing glucose concentration. Also disclosed is a monolithic device with an integrated lance (83).

L'invention concerne un capteur de glucose pr~sent~ sous la forme d'un timbre transdermique (2) ~ micro-aiguille (4) p~n~trant sans douleur dans la peau pour pr~lever du liquide interstitiel, lequel est achemin~ vers un orifice d'entr~e commune (7). Le timbre comporte une s~rie de microcanaux (8). Le liquide achemin~ sur le timbre est r~parti en commutation s~lective entre un certain nombre de microcanaux (8) par le biais de pompes ~lectro-osmotiques (10) et de portes hydrophobes (12). Chaque microcanal (8) comporte un d~tecteur ~lectrochimique (11) d~celant la concentration de glucose. L'invention concerne ~galement un dispositif monolithique ~ lance int~gr~e (83).
