Abstract

Abstract Three embodiments of a single-step lancet are disclosed. Each such lancet embodiment provides true one-step operation. In a single operational step requiring only a unidirectional displacement of an actuator into a housing, a lancet blade is removed from an aseptic environment which protects and retains the lancet blade in a pre-sterilized state within the housing prior to use, stores energy in an energy storage medium, activates the lancet blade to perform a lance and for safety retracts the lancet blade into the housing.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 258 words
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.
Claim 2
Dependent Claim 258 words
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.
Claim 3
Dependent Claim 32 words
A self-contained lancet according to claim 1 further comprising apparatus for sweeping undesirable material within said housing from the region of said slot to clear an unobstructed pathway for said lancet blade.
Claim 4
Dependent Claim 22 words
A self-contained lancet according to claim 1 wherein said actuator and said energy storing member are formed as a single integrated part.
Claim 5
Dependent Claim 25 words
A self-contained lancet according to claim 1 wherein said removable covering and a portion of said stripping apparatus are formed as a single integrated part.
Claim 6
Independent Claim 345 words
A method for using a self-contained lancet which requires but one operational step to perform a lancing procedure, comprising the steps of: providing a lancet comprising: a housing comprising an elongated contiguous side wall which surrounds and shelters lancet parts residing within said housing, said housing further comprising an 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 lancet blade covering, removable by action 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 therefrom; 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 displacement of the actuator; displacing the actuator unidirectionally from the first state to the second state thereby storing energy in the energy storing member and separating the lancet blade from the removable covering during the first portion of actuator displacement from the first state to the second state and then releasing the energy storing member during the second portion of actuator displacement from the first state to the second state to discharge the lancet from the housing and return the lancet into the housing.
Claim 7
Independent Claim 345 words
A method for using a self-contained lancet which requires but one operational step to perform a lancing procedure, comprising the steps of: providing a lancet comprising: a housing comprising an elongated contiguous side wall which surrounds and shelters lancet parts residing within said housing, said housing further comprising an 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 lancet blade covering, removable by action 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 therefrom; 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 displacement of the actuator; displacing the actuator unidirectionally from the first state to the second state thereby storing energy in the energy storing member and separating the lancet blade from the removable covering during the first portion of actuator displacement from the first state to the second state and then releasing the energy storing member during the second portion of actuator displacement from the first state to the second state to discharge the lancet from the housing and return the lancet into the housing.
Claim 8
