Puncturing system and lancet carrier tape

A puncturing system comprising:

• a carrier tape that carries multiple lancets, wherein each of the lancets are positioned such that a longitudinal direction of the lancet is transverse to a longitudinal direction of the carrier tape at a point of attachment of the lancet,
• a device housing comprising a conveying facility for moving the lancets into a usage position consecutively by moving the carrier tape in a conveying direction,
• a puncturing drive for accelerating one of the lancets that is positioned in the usage position in a puncturing motion,
• an opening in the device housing for touching against a body part in which a puncture is to be made by the puncturing motion of one of the lancets,
• an actuation facility for driving the conveying facility, the actuation facility comprising a substantially linear gear rack directly engaging a gearwheel and a counting wheel, the gearwheel and the counting wheel completely enclosed within the device housing;
• and
• an unlockable interlock comprising a stop that blocks further transport of the carrier tape as soon as one of the lancets has reached the usage position, wherein the interlock comprises an interlocking element that acts in conjunction with one of the lancets that is in the usage position.
