Single use lancet device
First Claim
1. A single use lancet device comprising:
- a) a housing, b) a lancet movably disposed within said housing and including a piercing tip, c) an actuation assembly mounted on said housing and releasably and drivingly connected to said lancet, d) said actuation assembly selectively movable to dispose said lancet at least into a cocked orientation, e) a driving assembly disposed in driving engagement with said lancet and structured to move said lancet from said cocked orientation at least temporarily into a piercing orientation, and f) a restriction assembly disposed and structured to restrict movement of said lancet from said piercing orientation into said cocked orientation.

Abstract
A single use lancet device having a housing, a lancet with a piercing tip movably disposed in the housing and structured to move between a cocked orientation and a piercing orientation, and a driving assembly structured to move the lancet into the piercing orientation. A retention member and an engagement hub are further provided and structured to be cooperatively engaged with one another upon the lancet being disposed in the cocked orientation so as to maintain the lancet in the cocked orientation until released by an actuation assembly. Specifically, the actuation assembly is structured to move between an actuated and an un-actuated orientation, movement into the actuated orientation releasing the retention member and the engagement hub from their cooperative engagement with one another and thereby result in movement of the lancet into the piercing orientation. The device also includes a restrictor assembly structured to substantially prevent the actuation assembly from moving out of the actuated orientation, thereby preventing re-firing of the lancet utilizing the actuation assembly.

29. A single use lancet assembly comprising:
-
a) a housing, b) a lancet movably disposed within said housing and including a piercing tip, c) an actuation assembly movably mounted on said housing in driving relation to said lancet, d) a positioning assembly movably and releasably interconnecting said actuation assembly and said lancet, e) said actuation assembly selectively positionable to dispose said lancet at least into a cocked orientation during concurrent engagement of said positioning assembly with said lancet and said actuation assembly, f) a driving assembly drivingly connected to said lancet, g) said driving assembly and said positioning assembly being cooperatively disposed and structured to force said lancet into said piercing orientation upon release of said positioning assembly from at least one of said actuation assembly or lancet, h) said driving assembly being disposed and structured to automatically move said lancet out of said piercing orientation and disposed said piercing tip into a retracted orientation, and i) a restriction assembly disposed and structured to restrict movement of said lancet from said piercing orientation into said cocked orientation.

30. A single use lancet assembly comprising:
-
a) a housing, b) a lancet movably disposed within said housing and including a piercing tip, c) an actuator movably disposed in driving engagement with said lancet, d) at least two engagement elements disposed to operatively interconnect said actuation assembly and said lancet at least upon engagement therebetween, e) said actuation assembly structured to position said lancet at least temporarily into a cocked orientation upon actuation thereof concurrent with said engagement between said engagement elements, f) a driving assembly drivingly engaging said lancet, g) said actuation assembly further structured to effect dis-engagement between said engagement elements upon continued actuation thereof after said lancet is disposed in said cocked orientation, and h) said driving assembly structured to move said lancet at least temporarily into a piercing orientation upon said disengagement between said engagement elements.
