LANCET Russian patent published in 2014 - IPC A61B5/151 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to devices for finger needling for blood sampling for analysis, specifically to lancets. A lancet with a flat handle which has an upper side and a lower side. At the front end, the lancet handle forms a blade which ends in a blade point. The blade has two cutting edges on the lower side converging to the point. On its lower side, the handle has at least one sampling socket. On its upper side on two edges converging to an apex, the handle passes into the blade. The upper side of the blade is convexly curved between the apex and the frond end when looking in a lateral section. According to the second version of the design, the handle has at least one sampling slot on its lower side. The slot comprises a section between the cutting edges wherein a cross sectional area of the slot decreases to the front end. On its upper side on two cutting edges converging to the apex, the handle passes into the blade, while the slot extends behind the apex. A needling system comprises one of the above lancets and a needling instrument which when needling causes a feed motion of the lancet followed by a return motion. The return motion is slower than the feed motion.

EFFECT: invention provides the least painful sampling procedure.
