Lancing Element, Lancing System and a Method for Skin Detection
First Claim
Patent Images
1. A lancing element for collecting a body fluid through skin, comprising:
- a support;
a lancing member which rigidly projects from the support configured to pierce a skin in a lancing movement; and
,a pretensioning means coupled to the support which tightens the skin near a puncture site, the pretensioning means having a contact member that impacts the skin during the lancing movement and moves back during the lancing movement in an opposite direction to the lancing member.

Abstract
In the case of a disposable lancing element for collecting body fluid through the skin comprising a support and a lancing member which distally projects therefrom and can pierce the skin in a lancing movement, it is proposed that a pretensioning means which tightens the skin in the area of the puncture site is arranged on the support and has a contact member which impacts the skin laterally from the lancing member during the lancing movement.

16. A lancing system for collecting a body fluid through the skin, comprising:
-
a support; a lancing member which rigidly projects from the support configured to pierce skin in a lancing movement; a pretensioning means coupled to the support which tightens the skin near a puncture site, the pretensioning means having a contact member that impacts the skin during the lancing movement and moves back during the lancing movement in an opposite direction to the lancing member; and
,a lancing drive for moving the lancing member forwards and backwards to create the lancing movement. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A system for skin detection during taking of body fluid samples, comprising:
-
a lancing element; a position detector for detecting the position of a skin relative to a movement axis of the lancing element; and
,a pretensioning means for locally tightening the skin when the position detector detects the position of the skin relative to a movement axis of the lancing element. - View Dependent Claims (24, 25, 26)

31. A lancing element with skin pretensioner for lancing depth control while collecting body fluid through skin, comprising:
-
a support; a lancing member coupled to the support and configured to rigidly project from the support to pierce skin during a lancing movement; and
,a pretensioner coupled to the support, the pretensioner having a contact member configured to impact skin during the lancing movement and move in a direction opposite to that of the lancing member during the lancing movement.

33. A method for controlling lancing depth during lancing to collect body fluid through a patient'"'"'s skin, comprising:
-
detecting the position of a skin relative to movement of a lancing element; tightening skin locally during detecting position of the skin with a pretensioner; retracting the lancing element from the skin after detecting the position of the skin; lancing the skin with the lancing element by advancing the lancing element into the skin; controlling movement of the lancing element according to the position of the skin to set a defined lancing depth; and
,withdrawing the lancing element by moving the lancing element away from the skin. - View Dependent Claims (34)
