Apparatus for acquiring and analyzing a blood sample
First Claim
1. An apparatus for obtaining and analyzing a blood sample,comprising:
- a housing;
a fixing device provided on the housing configured for contacting a body part from which a blood sample is to be taken;
at least one lancet configured for piercing the skin of the body part and being retracted;
at least one analysis element configured to be guided to the body part to take up a blood sample exiting the puncture wound;
a movably mounted holder to which the lancet and the analysis element can be coupled;
a piercing drive configured to drive the holder to execute the movements of the at least one lancet and the at least one analysis element;
a movement controller configured to guide the holder on a first movement path during which one of the at least one lancet performs a puncture movement along a puncture axis and a second movement path during which one of the at least one analysis element makes an offset movement transverse to the puncture axis;
the movement controller comprising a three-dimensional guide slot having first and second guide paths which have different depths, the contour of the first guide path determining the first movement path and the contour of the second guide path determining the second movement path; and
at least one guide element which travels along the guide slot.

Abstract
An automatic apparatus for obtaining and analyzing a blood sample contains a supply of lancets and test strips, which are located alternately on a carrier band. A lancet or alternatively a test strip may be clamped on a holder, which is mounted so it is movable. The movement controller of the holder comprises a three-dimensional control curve and a guide element, which engages at different depths in the control curve as a function of its relative position. The control curve comprises two guide paths, which run on different parallel planes. The contour of the first guide path determines the movement path of the lancet and the contour of the second guide path determines the movement path of the test strip. The test strip executes a transverse offset perpendicular to the puncture axis of the lancet.
