Abstract
A lancet device includes a housing with a cantilever spring extending therein and defining a lancet having a puncturing end on the cantilever spring. An actuator extends within the housing through an opening at the forward end. The actuator includes an interfering engagement with the cantilever spring. Movement of the actuator into the housing through the forward end pivots the cantilever spring against its relaxed condition and then releases the engagement with the cantilever spring, thereby permitting the cantilever spring to pivot the lancet structure to an extended position with the puncturing end extending through the forward opening, and to return to the relaxed condition retracting the puncturing end back within the housing.
