LANCET COMPRISING A TEST REGION
First Claim
1. A lancet, comprisinga base body, which has a test region on an upper face for analyzing a body fluid sample,a lancing element extending from the base body for puncturing the skin of a patient, anda capillary structure for transporting a body fluid sample from the lancing element to the test region, wherein at least a section of the capillary structure is a capillary channel, and wherein in a top view of the upper face, the test region is disposed laterally offset in relation to the longitudinal direction of the lancing element, and the capillary structure has a section that transports fluid sideways, and whereinthe base body comprises a coupling region for coupling the lancet to a lancing drive of a hand-held device,a rectilinear starting section of the capillary structure is arranged in the lancing element, and the coupling region is disposed so that a geometrical straight line, which is defined by the starting section of the capillary structure, intersects the coupling region,characterized in thatthe capillary channel has a bend with rounded corners or a curve and a cross-sectional surface, in the region of the bend or curve, that is no larger than in an adjoining section, and wherein the coupling region is disposed in a straight line behind the lancing element and laterally beside the test region.

Abstract
The invention relates to a lancet, comprising a base body (2), which has a test region (3) on an upper face for analyzing a body fluid sample, a lancing element (4) extending from the base body (2) for puncturing the skin of a patient, and a capillary structure (5) for transporting a body fluid sample from the lancing element (4) to the test region (3). According to the invention, the capillary structure (5) comprises a section that causes fluid to be transported in a direction that, in a top view of the upper face of the base body (2), has a component perpendicular to the longitudinal direction of the lancing element (4).
