Abstract
A lancet device, a tip for a lancet device and method of using the lancet device. The lancet device has a body portion for firing the lancet and a tip portion. The tip for a lancet device includes a front assembly which includes a side wall portion, a skin-engaging portion at least partially defining a plane beyond which a lancet needle may extend, and a lancet stop element, a slot is disposed in one of the sidewall portion and the lancet stop element, and at least one following element extending into the slot, wherein the lancet stop element is moveable towards and away from the plane in response to movement of the at least one following element. The method includes adjusting a set depth of penetration of the needle by moving the at least one following element, disposing the distal end of the lancet device against a surface of skin, and triggering the firing mechanism to cause the needle to penetrate the surface of the skin to the set depth, wherein the puncture allows a blood sample to be taken.
