Abstract
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.
