1. A lancet device, comprising:
a housing comprising an internal cam surface at a rearward end thereof;
a shield at least partially disposed within the housing and movably associated therewith;
a lancet disposed in the housing and axially movable through the shield and comprising a puncturing element, the lancet adapted for axial movement between an initial position wherein the puncturing element is disposed within the housing and a puncturing position wherein the puncturing element extends through a forward opening in the shield for a puncturing procedure;
a drive spring disposed between the rearward end of the housing and the lancet for biasing the lancet to the puncturing position; and
an actuator associated with a proximal end of the shield disposed in the housing, and in interference engagement with the lancet in the initial position thereof;
wherein axial movement of the shield into the housing causes the actuator to move the lancet toward the rearward end of the housing to at least partially compress the drive spring while simultaneously interacting with the internal cam surface, and wherein continued interaction with the internal cam surface during the shield axial movement moves the actuator to a position within the housing where the interference engagement between the actuator and the lancet is released, thereby releasing the at least partially compressed drive spring and permitting the drive spring to bias the lancet through the shield to the puncturing position; and
wherein the actuator comprises a plate member slidably associated with the shield proximal end and defining a keyhole for permitting passage of the lancet therethrough to release the interference engagement.
