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.
Claims21
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.
A lancing system comprising a lancet and a lancing device for receiving and discharging said lancet;
- said lancet comprising a lancet body having a proximal end and a distal end, and a sharp lancing tip projecting axially from the proximal end of the lancet body;
- and
- said lancing device comprising an ejector arm having an ejection actuator at a first end thereof and an abutment finger projecting from the ejector arm for abutment against the distal end of the lancet upon operation of the ejection actuator.
A lancing device comprising:
- an outer housing;
- a lancet carrier translationally movable within the housing;
- and
- an inner guidance housing mounted within the outer housing for constraining the lancet carrier to axial movement along a linear lancing stroke.
A lancing device comprising:
- a lancet carrier comprising a lancet carrier stop;
- a drive spring for propelling the lancet carrier along a lancing stroke defining a stroke distance;
- and
- a depth control mechanism comprising:
- a dial that is rotational about a center of rotation, the dial further comprising a mounting pin eccentrically offset from the center of rotation;
- and
- a stop bar having a first end mounted to the mounting pin of the dial and a second end comprising a stop surface for contact with the lancet carrier stop to adjust the stroke distance of the lancet carrier.
