2123400 9309723 PCTABS00022 A lancet device includes a body (242) within which is slidably located a trigger (224) and fixedly located a base. The base (214) contains, in an armed position, the lance (202) with its needle (204) and a spring affixed to the lance. The trigger includes means to release the lance during use. In 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 trigger and pierces the tissues. Because the spring is held in a pre-armed position, release of the spring is consistent, and reproducibility of incision is well controlled. |
