LANCING DEVICE COMPRISING A TORSIONAL SPRING
First Claim
1. A lancing device for taking blood for medical examinations, comprising a base body, at least one needle which is arranged therein and which can be extended outwards with a tip end, a needle holder which at least partially encompasses the needle, a manual actuator for releasing a displacement movement of the needle, a control curve section, and a torsional spring that engages in the control curve section, wherein the control curve section and the torsional spring are arranged with respect to the needle holder in order to transform a radial movement of first and second ends of the torsional spring into translational displacement movement of the needle.

Abstract
A lancing device for taking blood for medical examinations, comprising a base body, at least one needle which is arranged therein and which can be extended outwards with a tip end, and a manual actuating element for releasing a displacement movement of the needle, wherein a control curve section and a torsional spring that engages in the control curve section are arranged in a needle holding element, which at least partially encompasses the needle, in order to transform a radial movement of ends of the torsional spring into a translational displacement movement of the needle.
