Abstract
A lancing device and lancet are provided with depth-control, lancet ejection, and/or guidance mechanisms. The depth-control mechanism includes a dial rotationally mounted at a distal end of the housing of the lancing device, the dial being coupled to a linkage whereby rotation of the dial imparts translational movement to a stop surface of the linkage to limit the stroke of the lancet and thereby control lancing penetration depth. The ejection mechanism includes an ejector that is advanced into contact with a transversely flared flange of the lancet to discharge the lancet from the lancing device. The guidance mechanism includes an inner guidance housing for restricting out-of-axis movement of a lancet carrier.
