Einwegelement zur Verwendung in einer Probenentnahmevorrichtung für Körperflüssigkeit

摘要

A disposable lancing element (12) is adapted for use in a lancing device (10) for making an incision through a user's skin. The lancing element (12) includes a body (16) which defines a longitudinal axis, and has a skin lancing member projecting from a front end thereof. A capillary tube (18) is mounted in the body in laterally spaced relationship to the skin lancing member, and is slidable longitudinally relative to the body (16) so as to be extended forwardly past the skin lancing member. The body (16) includes a plurality of circumferentially spaced, radially outwardly projecting bosses (31) formed thereon for guiding the disposable element installation in a carrier element. The kin lancing member may comprise a plurality of needles (14) or barbs arranged in parallel side by side relationship. In lieu of a skin lancing member, the disposable element (12) may possess a longitudinal through hole for conducting a skin piercing laser light beam or pressurized fluid. A capillary tube (18) may have an outwardly flared lower (inlet) end. A capillary tube (18) may possess a sensor for sensing a level of fluid rising therein.
