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.
Claims22
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 mechanism 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, a sharp lancing tip projecting axially from a proximal end of the lancet body, and a flared flange projecting transversely from the lancet body;
- and
- said lancing device comprising an ejection mechanism comprising an abutment member for contacting the flared flange of said lancet and ejecting the lancet from the lancing device.
A lancet comprising a lancet body, a sharp lancing tip projecting axially from a proximal end of the lancet body, and a flared flange projecting transversely from the lancet body.
A lancing system comprising a lancet and a lancing device for receiving and discharging said lancet;
- said lancet comprising a lancet body, a sharp lancing tip projecting axially from a proximal end of the lancet body, and a recess in the lancet body;
- and
- said lancing device comprising an ejection mechanism having a protrusion for engaging the recess in the lancet body and pushing on the lancet body to eject the lancet from the lancing device.
A lancet comprising a lancet body, a sharp lancing tip projecting axially from a proximal end of the lancet body, and a recess in a side of the lancet body for engagement with an ejector of a lancing device.
