Abstract:
An electronic lancing device comprising:a housing; a hollow, cylindrical-shaped shell having at least one guide arm, said shell being fixedly mounted within the housing; a magnet fixedly mounted in said shell; a bobbin being partially disposed in said rigid shell for reciprocating movement therein, said bobbin being moveable from a retracted position to an activated position and from the activated position to the retracted position, said bobbin being constrained to one directional translation motion by said at least one guide arm of said shell when moving from the retracted position to the activated position and from the activated position to the retracted position; a coil having at least one winding disposed around said bobbin, said coil being attached to said bobbin; a lancet removably attached to said bobbin; and an electronic circuit electrically coupled to said coil for controlling the movement of said bobbin, said electronic circuit supplying current in a first direction to said coil to create a repulsive magnetic field in the coil causing the coil and the bobbin to be repulsed by the magnetic for moving said bobbin from the retracted position to the activated position said electronic circuit supplying current in a second direction to said coil to create an attractive magnetic field in the coil causing the coil and the bobbin to be attracted by the magnetic for moving said bobbin from the activated position to the retracted position, said second directed being the reverse of said first direction.
