A disposable lancet device adapted to pierce human skin sufficiently to let a small quantity of blood for testing. The device includes a lancet housing, a lancet body displaceably supported by the housing, and a piercing tip concealed within the housing in a rest position. The piercing tip can be integral with the lancet body or attached thereto. The device also includes an actuator for manually displacing the lancet body to expose the piercing tip under applied force and a return mechanism that returns the lancet body to the rest position when the manual displacement force is removed from the actuator. The actuator can be disabled to inhibit further manual displacement of the lancet body and exposure of the piercing tip. Thus, the piercing tip can be repeatedly exposed if desired, but can also be disabled once further use is no longer desired. |
