Abstract
A disposable lancet for piercing a person's finger skin sufficiently to let a small quantity of blood. The lancet includes a long, slender, rigid shank having a hypodermic needle-style piercing tip at one end and slidably mounted within a generally coextensive support tube over substantially its entire length. A cap is connected to the other end of the shank which, when in contact with one end of the support tube, is structured to allow the piercing tip to extend beyond the other end of the support tube a predetermined distance sufficient for piercing the skin. The shank has a stored position wherein the piercing tip is retracted fully within the support tube. Single-use features are also disclosed.
