Lancing device for obtaining samples of body fluid

A lancing device for obtaining bodily fluid samples comprising:

• a) a base body, which is rotationally symmetrical about a 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 a tip thereof exits the outlet opening during the back and forth movement,
• d) a transport device for further transportation of the lancets held in the lancet magazine,
• e) the outlet opening being arranged centrally in the positioning face so as to be co-axial with the longitudinal axis,
• f) the lancet magazine having a guidance path for the lancets, such that the lancet to be moved back and forth in the longitudinal direction by the drive device is transported to a center position of the device wherein the central position is co-axial with the longitudinal axis and the outlet opening,
• wherein the drive device is able to contact the lancet to be moved back and forth at this central position and move the lancet to be moved back and forth through the base body so that the lancet tip exits the outlet opening during the back and forth movement, wherein
• g) lancets in the transport device for further transportation of the lancets held in the lancet magazine are displaceably held in a plane which is perpendicular to the longitudinal axis,
• h) the guidance path is formed in a non-circular path about the longitudinal axis of the lancing device such that the lancet to be moved back and forth in the longitudinal direction by the drive device is transported from an outer edge of the lancing device to the center position of the device so as to be aligned with the centrally positioned outlet opening,
• i) in each case, the drive device for moving the 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 wherein the lancet is guided in a lancet body, and
• j) the guidance path of the lancet magazine is formed to receive an open or closed lancet band;
• wherein the guidance path is non-linear within a plane perpendicular to the longitudinal axis, or non-linear within a plane parallel to the plane perpendicular to the longitudinal axis.
