Abstract:
1. A lancing device, for use with a lancet for lancing body tissue to result in a wound for bleeding, the lancing device comprising: (1) a generally annular housing having a central axis and an internal channel extending along the central_axis terminating at a priming end of the housing and at an opposed lancing end of the housing; (2) a priming knob rotatably and translationally connected about the housing to permit rotation about an axis of rotation generally parallel to the central axis of the housing and translation in a direction parallel to the axis of rotation, wherein the priming knob comprises a slanted priming notch for priming interaction with a priming protrusion of a lancet carrier, (3) a lancet carrier translationally mounted within the internal channel of the housing for carrying a lancet along a strike path that is generally parallel with the central axis, the strike path of the lancet carrier starting from a primed position toward the priming end of the housing wherein the lancet is shielded by the housing and ending at a lanced position wherein a tissue penetrating portion of the lancet extends outwardly from the lancing end of the housing, the lancet carrier comprising a priming protrusion for priming interaction with the slanted priming notch of the priming knob; and (4) a lancet carrier driver disposed within the internal channel of the housing, the lancet carrier driver being operatively engaged with the lancet carrier when driving the lancet carrier along the strike path from the primed position to the lanced position; wherein when the slanted priming notch is in priming interaction with the priming protrusion of the lancet carrier: (i) rotation of the priming knob is by itself sufficient to prime the lancet driver and places the lancet carrier into a primed position; (ii) movement of the priming knob along an axis generally parallel to the central axis of the housing is by itself sufficient to prime the lancet driver and places the lancet carrier into a primed position and (iii) a combination of both rotation of the priming knob and movement of the priming knob along an axis generally parallel to the central axis of the housing, prunes the lancet driver and places the lancet carrier into the primed position.
