Lancing device and lancet
First Claim
1. A lancing device comprising a housing, a lancet carrier mounted within said housing for movement between a retracted position and a lancing position, and a depth-control mechanism, said depth-control mechanism comprising a dial rotationally mounted relative to said housing, and a linkage coupled to said dial and having a stop member for limiting travel of the lancet carrier at the lancing position, wherein rotation of the dial causes movement of the linkage to adjust a point of contact of the lancet carrier with the stop member relative to the housing, and wherein the linkage comprises a stop bar having a generally T-shaped profile with a lengthwise axis and a traverse rib forming the stop member and extending generally perpendicular to the lengthwise axis.

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.

- 1. A lancing device comprising a housing, a lancet carrier mounted within said housing for movement between a retracted position and a lancing position, and a depth-control mechanism, said depth-control mechanism comprising a dial rotationally mounted relative to said housing, and a linkage coupled to said dial and having a stop member for limiting travel of the lancet carrier at the lancing position, wherein rotation of the dial causes movement of the linkage to adjust a point of contact of the lancet carrier with the stop member relative to the housing, and wherein the linkage comprises a stop bar having a generally T-shaped profile with a lengthwise axis and a traverse rib forming the stop member and extending generally perpendicular to the lengthwise axis.
- 17. A lancing device comprising a housing, a lancet carrier mounted within said housing for movement in an axial direction between a retracted position and a lancing position, at least one spring for driving the movement of the lancet carrier, and a depth-control mechanism, said depth-control mechanism comprising a dial rotational about an axis generally transverse to the axial direction, and a linkage coupled to said dial and having a stop member for limiting travel of the lancet carrier at the lancing position, wherein rotation of the dial causes movement of the linkage to adjust a point of contact of the lancet carrier with the stop member relative to the housing, and wherein the linkage comprises a stop bar having a generally T-shaped profile with a lengthwise axis and a traverse rib forming the stop member and extending generally perpendicular to the lengthwise axis.
