A novel two part lancing device comprising a multiple compartment housing for lancets and a carrier. The compartments are joined in a common multiple lancet housing for improved handling and distribution. The housing consists of two end compartments and at least two serially linked, frangibly separable, disposable lancet compartments which comprise presterilized, self-actuating lancets. When fired, each lancet, driven by a precocked torsion spring, executes one reciprocal cycle wherein the lancet tip is driven outward a precise distance to lance a patients finger or the like and is then fully retracted into the housing compartment. The spent lancet can be frangibly separated from the housing to provide access to the next-to-be-used lancet which remains aseptically pure until the moment of separation of the spent lancet. Because the used lancet tip is fully retracted into the housing, the separated lancet compartment can be safely discarded without special handling. The carrier is a handler for the lancet housing and provides a convenient tool of constant length and "feel" for positioning and firing the lancets. |
