Abstract
A lancing device comprising a lancet holder for holding an exchangeable lancet and comprising a drive element for driving the lancet holder. The drive element has two spring elements comprising a lancing spring element for accelerating the lancet holder in the lancing direction and a restoring spring element for accelerating the lancet holder counter to the lancing direction. The drive element has a carriage unit with a spring-tensioning carriage part and a lancing carriage part, and the spring-tensioning carriage part and the lancing carriage part are arranged to be displaceable in translation relative to one another and form a lancing spring element receiving region and a restoring spring element receiving region. The lancing spring element receiving region can be reduced by translational displacement of the spring-tensioning carriage part relative to the lancing carriage part, in order to pre-tension the lancing spring element within the lancing spring element receiving region.
