English to French Tech/Engineering Patents TRIGGER ACTIVATED LANCET

Such force applied across the bow spring biases the bow spring against the first state (in which the bow spring is résistive to movement) to a second state in which the bow spring stores energy or is otherwise stressed, thereby extending the lancet structure to the puncturing position.

Latéral movement of the trigger into the housing, i.e. pivotai movement of the trigger, causes this distance between the pivot axis and the puncturing end of the lancet structure to increase, based on the trigger biasing and deflecting the bow spring.

Desirably, latéral movement of the trigger into the housing biases the bow spring against a state in which the bow spring is résistive to movement, thereby extending the lancet structure to the puncturing position, and subsequently releases the bias against the bow spring.

In this manner, the latéral trigger movement causes an initial biasing of the bow spring and a sequential release of the bias against the bow spring, causing it to return toward the condition or state in which it is résistive to movement, thereby retracting the lancet structure to the retracted position.

The trigger may preferably be maintained witliin the housing upon latéral movement of the trigger into the housing, and is desirably locked within the housing upon latéral movement of the trigger into the housing to a position in which the bias against the bow spring is released.

The trigger may include a cam surface for camming engagement with the bow spring for biasing the bow spring against the first state.

As such, latéral movement of the trigger into the housing causes a portion of the trigger to contact an opposing side of the apex of the bow spring to bias the bow spring against its first state to extend the lancet structure to the puncturing position.
