ABSTRACT:
A lancet device includes a body within which is slidably located a trigger and fixedly located a base. The base contains, in an armed position, the lance with its needle and a spring affixed to the lance. The trigger includes a mechanism to release the lance during use.
In a preferred embodiment, the lancet device of the present invention is self-activated by the finger (or other body part) to be pierced. Depression of the trigger with the finger releases the lance and the spring so that the needle protrudes through an orifice in the end of the trigger and pierces the tissue. Because the spring is held in a pre-armed position, release of the spring is consistent, and reproducibility of incision is well controlled.
