Abstract
The application relates to a lancing device for obtaining samples of body fluid, said device comprising: a base body which is rotationally symmetrical with relation to the longitudinal axis thereof and on one longitudinal end of which a positioning surface with an exit opening is arranged; a lancet cartridge for receiving a plurality of lancets; a drive device for moving a lancet held in the lancet cartridge back and forth along the longitudinal axis; and a transport device for transporting lancets on a plane perpendicular to the longitudinal axis. The exit opening is located substantially centrally in the positioning surface and the lancet cartridge has a guide track for the lancets, in which track said lancets can be positioned in such a way that their tips can emerge from the exit opening during the movement back and forth.

16. A lancing device for obtaining bodily fluid samples comprising:
-
a) a base body, which is substantially rotationally symmetrical about the longitudinal axis thereof, which, on one longitudinal-face end thereof, has a positioning face with an outlet opening, b) a lancet magazine for receiving a plurality of lancets, which is held replaceably in the base body, c) a drive device for moving a lancet arranged in the lancet magazine back and forth in the direction of the longitudinal axis, said lancet being positioned therein in such a way that the tip thereof can exit the outlet opening during the movement back and forth, d) a transport device for further transportation of the lancets held in the lancet magazine, e) the outlet opening being arranged substantially centrally in the positioning face, f) the lancet magazine having a guidance path for the lancets, in which the lancets can be positioned in such a way that the tips thereof can exit the outlet opening during the movement back and forth, characterised in that g) the lancets in the transport device for further transportation of the lancets held in the lancet magazine are displaceably held in a plane perpendicular to the longitudinal axis, h) the guidance path is formed in a non-circular path about the longitudinal axis of the lancing device, and in that, i) in each case, the drive device for moving a lancet arranged in the lancet magazine back and forth in the direction of the longitudinal axis merely moves one of the lancets in the lancet magazine back and forth in the direction of the longitudinal axis. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 31)
