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.

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.
A lancing device for taking blood for medical examinations, comprising:
- a base body;
- at least one needle having a tip end and configured within the base body to extend outwards with the tip end;
- a needle holder at least partially encompassing the needle;
- a manual actuator movable connected to the base body and configured to release a displacement movement of the needle and the needle holder relative to the base body;
- a control curve section;
- and
- a torsional spring configured to engage 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 ends of the torsional spring into displacement movement of the needle.
A lancing device for taking blood for medical examinations, comprising:
- a base body;
- at least one needle having a tip end and configured within the base body to extend outwards with the tip end;
- a needle holder arranged in a stationary manner in the base body and at least partially encompassing the needle;
- a manual actuator movable connected to the base body and configured to release a displacement movement of the needle relative to the needle holder and the base body;
- a control curve section;
- and
- a torsional spring configured to engage 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 ends of the torsional spring into translational displacement movement of the needle.
