Lancing system
First Claim
1. Lancing system havinga lancet carrier tape that supports a plurality of lancets arranged transversely to its longitudinal direction;
- a transport means serving to move the lancet carrier tape in a transport along a transport path and to thereby move lancets of the lancet carrier tape one after the other to a puncturing position; and
a lancing drive for causing a lancet that occupies a puncturing position to perform a puncturing movement, whereinduring a puncturing movement the lancing drive moves a lancet, that has been brought to a puncturing position, in the puncturing direction together with a portion of the lancet carrier tape on which that lancet is supported and thatonce a lancet has been moved to the puncturing position at least one element of the transport means, arranged behind the puncturing position in the transport direction, performs a compensating movement before or during the puncturing movement of that lancet; and
wherein the lancet remains fixed to the portion of the lancet carrier tape during the puncturing movement, wherein the compensating movement allows the lancet and the portion of the lancet carrier tape to move together during the puncturing movement.

Abstract
The invention relates to a lancing system having a lancet carrier tape (3) supporting a plurality of lancets (4), a transport means (5, 11, 17) serving to move the lancet carrier tape (3) in a feed or transport direction along a transport path and to thereby move lancets (4) of the lancet carrier tape (3) one after the other to a puncturing position, and a lancing drive (6) for causing a lancet (4) that occupies a puncturing position to perform a puncturing movement. It is provided according to the invention that during a puncturing movement the lancing drive (6) moves a lancet (4), that has been brought to a puncturing position, in the puncturing direction together with a portion of the lancet carrier tape (3) on which that lancet (4) is supported and that once a lancet (4) has been moved to the puncturing position at least one element of the transport means (5, 11, 17), arranged behind the puncturing position in the transport direction, performs a movement before or during the puncturing movement of that lancet (4).

20. A lancing system, comprising:
-
a lancet carrier tape; a plurality of lancets attached to the lancet carrier tape; a lancing drive for causing at least one of the lancets on the lancet carrier tape to perform a puncturing movement, wherein a portion of the lancet carrier tape moves with the lancet during the puncture movement; and at least one tape guide element guiding the lancet carrier tape, wherein the guide element is rotatable about an axis that is arranged eccentrically relative to the guide element, the guide element being rotatable about the axis to release tension in the lancet carrier tape during the puncturing movement. - View Dependent Claims (21, 22)

23. A lancing system, comprising:
-
a lancet carrier tape extending in a longitudinal direction between two rollers; a lancet attached to the lancet carrier tape, wherein the lancet extends transversely to the longitudinal direction of the lancet carrier tape; a lancing drive configured actuate the lancet to form an incision, wherein a portion of the lancet carrier tape to which the lancet is attached moves with the lancet during actuation of the lancet by the lancing drive; a first guide element guiding the lancet carrier tape between the two rollers; a second guide element guiding the lancet carrier tape between the two rollers; wherein at least one of the first and second guide elements is moveable during actuation of the lancet to provide slack for the portion of the lancet carrier tape that moves with the lancet; and wherein the lancet remains fixed to the portion of the lancet carrier tape during actuation of the lancet. - View Dependent Claims (24)

25. A method, comprising:
-
providing a lancet fixed to a lancet carrier tape, wherein the lancet is oriented in a transverse direction relative to a longitudinal direction of the lancet carrier tape; indexing the lancet to a puncturing position by winding the lancet carrier tape on a winding device; unwinding a length of the lancet carrier tape from the winding device after said indexing the lancet to the puncturing position; performing a puncturing movement with the lancet in the transverse direction, wherein the lancet remains fixed to the lancet carrier tape during said performing the puncturing movement; and wherein said unwinding the length of the lancet carrier taper occurs before or during said performing the puncturing movement so as to compensate for the puncturing movement. - View Dependent Claims (26)
