SINGLE USE LANCET ASSEMBLY
First Claim
1. A single use lancet device comprising:
- a housing;
a lancet;
said lancet including a piercing tip;
said lancet at least partially disposed in said housing and structured to move at least between a cocked orientation and a piercing orientation;
a biasing element structured to move said lancet at least temporarily into said piercing orientation;
an actuator structured to be actuated by a user so as to result in said biasing element moving said lancet at least temporarily into said piercing orientation;
a restrictor assembly, at least part of said restrictor assembly being independent of said biasing element, and said lancet, and when engaged structured to prevent said lancet from being moved back into said cocked orientation after movement of said lancet at least temporarily into said piercing orientation as a result of an implement pushing merely said lancet; and
said restrictor assembly being isolated from external, engagement restricting contact with the user during movement of said lancet into said piercing orientation.

Abstract
A single use lancet device having a housing, with an open interior and an access opening defined therein, a lancet, with a body and a piercing tip, and disposed in the open interior of the housing so as to move between a cocked orientation and a piercing orientation, a driving assembly structured to move the lancet into the piercing orientation, and a restrictor assembly having a shoulder element and a restrictor panel operatively associated with the lancet and the housing and structured to pass over the restrictor panel upon the lancet moving from its cocked orientation to its piercing orientation, and to abut the restrictor panel upon attempted movement of the lancet back into its cocked orientation after movement into the piercing orientation, thereby preventing the lancet from moving back into the cocked orientation and preventing re-use of a contaminated piercing tip.

1. A single use lancet device comprising:
-
a housing; a lancet; said lancet including a piercing tip; said lancet at least partially disposed in said housing and structured to move at least between a cocked orientation and a piercing orientation; a biasing element structured to move said lancet at least temporarily into said piercing orientation; an actuator structured to be actuated by a user so as to result in said biasing element moving said lancet at least temporarily into said piercing orientation; a restrictor assembly, at least part of said restrictor assembly being independent of said biasing element, and said lancet, and when engaged structured to prevent said lancet from being moved back into said cocked orientation after movement of said lancet at least temporarily into said piercing orientation as a result of an implement pushing merely said lancet; and said restrictor assembly being isolated from external, engagement restricting contact with the user during movement of said lancet into said piercing orientation. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. A single use lancet device comprising:
-
a housing; a lancet; said lancet disposed at least partially in an interior of said housing and structured to move relative to said housing; a biasing element structured to move said lancet into a second position relative to said housing wherein said lancet pierces a patient'"'"'s skin from a first position relative to said housing wherein said lancet is disposed immediately prior to being moved by said biasing element towards and into said second position; an actuator structured to be actuated by a user so as to result an said biasing element moving said lancet; and an abutment structure, at least part of said abutment structure being independent of said biasing element, said lancet, and externally engagable portions of said actuator, and cooperatively disposed between said housing and said lancet, said abutment structure structured to prevent movement of said lancet back into said first position relative to said housing after movement of said lancet into said second position relative to said housing as a result of an implement pushing merely said lancet towards said first position relative to said housing and independently of user interaction with said actuator after said lancet has moved into said second position, and said abutment structure being isolated from external, engagement restricting contact with the user during movement of said lancet into said second position.

11. A single use lancet device comprising:
-
a housing; a lancet; said lancet including a piercing tip; said lancet at least partially disposed in said housing and structured to move at least between a cocked orientation and a piercing orientation; a biasing element structured to move said lancet at least temporarily into said piercing orientation; an actuator structured to be actuated by a user so as to result in said biasing element moving said lancet at least temporarily into said piercing orientation; a restrictor assembly independent of said biasing element and structured to engage said lancet independently of user interaction with said actuator after said lancet has moved into said piercing orientation, and thereby prevent said lancet from being moved back into said cocked orientation after movement of said lancet at least temporarily into said piercing orientation merely as a result of an implement pushing said lancet; said restrictor assembly including a shoulder element and a restrictor panel, said restrictor panel and said shoulder element structured to pass one another upon said lancet moving from said cocked orientation to said piercing orientation, and to abut one another upon attempted movement of said lancet into said cocked orientation after movement into said piercing orientation; said shoulder element including a biased finger extending from said lancet; said restrictor panel including a protruding element protruding from said housing; and said shoulder element and said restrictor panel being isolated from external, engagement restricting contact with the user during movement of said shoulder element and said restrictor panel past one another when said lancet is moving into said piercing orientation.
