Abstract
A lancet or finger-stick device operable to make a small incision into the vascular tissue of the skin to induce a controllable blood flow is particularly suited for incisions of the finger-tip of a patient. The device and method provide multiple use by a single-user in that the device provides an autologous re-use feature, such that an individual can reset and reuse the device on the same patient in case of an accidental misfire prior to actual use or if the first incision does not provide a sufficient blood sample. A disabling mechanism which the individual performs immediately prior to disposal of the used device is incorporated into the invention. These features permit the user of a consumer self-test or professional-use test to re-stick an individual's fingertip in the event that the first try is unsuccessful or the blood flow is inadequate. It also insures sterility of the unused unit and provides enhanced safety since the device cannot be accidentally fired or reused by another individual after being disposed.
