A bodily fluid sampling device comprising a lancet which can be advanced against a skin-piercing site to produce a droplet of bodily fluid. A transport medium is positioned sufficiently close to the lancing medium to retain a droplet of bodily fluid therebetween by capillary action. One of the two mediums has hydrophobic material on its surface and the other hydrophilic. Various mechanisms are provided for relatively displacing the lancing and transport medium to move the droplet of bodily fluid away from the skin- piercing end. Furthermore, multiple lancet assemblies may be provided in a barrel or disk configuration and indexed to the displacing mechanisms for sampling a skin site.

L'invention concerne un dispositif destiné au prélèvement de liquides organiques, comprenant une lancette pouvant être utilisée pour percer la peau et obtenir une gouttelette de liquide organique. Le dispositif comprend également un support situé suffisamment près de la lancette, permettant de retenir une gouttelette de liquide organique par action capillaire. La lancette ou le support comprend une matière hydrophobe à sa surface et l'autre une matière hydrophile. Divers mécanismes permettent de déplacer la lancette et le support de manière à éloigner la gouttelette de liquide organique de l'extrémité de la lancette utilisée pour percer la peau. Par ailleurs, plusieurs ensembles de lancettes peuvent être fournis dans un cylindre ou un disque et rattachés aux mécanismes de déplacement pour la réalisation de prélèvements de peau.
