Lancing device for taking blood samples

摘要

The apparatus (1) has an axially displaceable lancet holder element (32) for holding a replaceable lancet (12). A drive unit (12) comprises a lancing spring element (31) for driving the axially displaceable lancet holder element in lancing direction (18). A tensioning carriage part (26) is fixed in a clamping position for tensioning the lancing spring element. The tensioning carriage part is temporarily fixed in the clamping position by using a snap-locking unit (35) that is engaged with the axially displaceable lancet holder element.
