Claim 7:
8. A lancing device for use with a disposable lancet having a lancet body and a sharp lancet tip for penetrating skin, comprising:
a housing defining a cavity;
a lancet carrier positioned within the cavity, the lancet carrier having a slot and being configured to releasably engage a disposable lancet, the lancet carrier being movable in a direction along a lancing stroke from a retracted position to an extended position where at least the sharp lancet tip of the disposable lancet is configured to project out from the housing;
a return spring positioned within the cavity and configured to propel the lancet carrier from the extended position to a neutral position;
a drive spring positioned within the cavity and configured to propel the lancet carrier from the retracted position to the extended position;
a removable cap positionable over a distal end of the housing, wherein removal of the cap from the housing allows access to the cavity in order to remove and replace the disposable lancet;
an ejection member having an ejection finger and an extension, the ejection finger extending through the slot to contact the disposable lancet and the ejection member being movable distally to eject the disposable lancet from the lancet carrier, the extension extending along the direction of the lancing stroke distally beyond the ejection finger, wherein a portion of the ejection finger extends longitudinally and is laterally offset relative to the extension; and
a button operably connected to the lancet carrier and configured to hold the lancet carrier in the retracted position and, when pressed, to release the lancet carrier and to allow the lancet carrier to move from the retracted position to the extended position.
