Abstract:
A self-contained lancet which requires but one operational step to perform a lancing procedure, said lancet comprising:a housing comprising an elongated contiguous side wall which surrounds and shelters lancet parts residing within said housing, said housing further comprising a substantially open first end wherethrough an actuator is unidirectionally displaced to energize and activate a lancing cycle and a slot on the other end through which a lancet blade is displaced; the lancet blade, disposed for transport before use and for disposal after use, within said housing; a covering, removed as a part of the single operational step, being protectively disposed to provide a sterile encasement about the lancet blade before use, said cover maintaining the lancet blade in an uncontaminated state until the lancet is uncovered during the single operational step; the actuator which is displaceable from a first state whereat digital access is provided toward and to a second state whereby the lancet is activated; an energy storing member which communicates with the actuator at a first site and is securely affixed to the lancet blade at a second site and which stores energy during a first portion of actuator displacement from the first state to the second state and released during a second portion of actuator displacement from the first state to the second state to discharge the lancet outward from the housing and then to return the lancet to protective safety of the housing; and a stripping apparatus which separates the lancet blade from the removable covering during the first portion of actuator displacement.
