Single use lancet device

Claim 2

A single use lancet device comprising: a) a housing; b) a lancet, said lancet including a piercing tip; c) said lancet movably disposed in said housing and structured to move at least between a cocked orientation and a piercing orientation; d) a driving assembly structured to move said lancet at least temporarily into said piercing orientation; e) an actuation assembly structured to move between an actuated and an un-actuated orientation, movement of said actuation assembly into said actuated orientation resulting in said movement of said lancet into said piercing orientation; and f) a restrictor assembly structured to substantially prevent said actuation assembly from moving out of said actuated orientation at least after said lancet has moved at least temporarily into said piercing orientation by said drive assembly.

Claim 3

The single use lancet device recited in claim 1 further comprising a retention member; and an engagement hub, said engagement hub structured to be cooperatively engaged with said retention member at least upon said lancet being disposed in said cocked orientation so as to maintain said lancet in said cocked orientation until said retention member is affirmatively released from said cooperative engagement therewith.

Claim 4

The single use lancet device recited in claim 2 wherein said actuation assembly is structured and disposed to release said retention member from said cooperative engagement with said engagement hub.

Claim 5

The single use lancet device recited in claim 3 wherein said retention member includes at least one finger, said finger including a depending protrusion structured to engage cooperative structure on said engagement hub when said lancet is disposed in said cocked orientation, said actuation assembly being structured to at least temporarily urge said finger out of said engagement with said cooperative structure on said engagement hub.

Claim 6

The single use lancet device recited in claim 1 further comprising a cocking assembly, said cocking assembly being operatively associated with said lancet and structured to move said lancet into said cocked orientation.

Claim 7

The single use lancet device recited in claim 5 wherein said cocking assembly is structured to protrude from said housing.

Claim 8

The single use lancet device recited in claim 5 wherein said cocking assembly is integrally formed with said lancet.

Claim 9

The single use lancet device recited in claim 5 wherein said cocking assembly includes a cocking element structured to extend into said housing and into movement engagement with said lancet.

Claim 10

The single use lancet device recited in claim 8 wherein said cocking element protrudes from a side of said housing so as to facilitate movement by a user's finger.

Claim 11

The single use lancet device recited in claim 1 wherein said lancet is structured to be maintained in said cocked orientation until released by said actuation assembly.

Claim 12

The single use lancet device recited in claim 10 wherein said actuation assembly includes a release element structured to release said lancet from said cocked orientation.

Claim 13

The single use lancet device recited in claim 11 wherein said restrictor assembly includes an abutment structure cooperatively disposed between said housing and said release element, and structured to prevent said actuation assembly from moving into said un-actuated orientation after movement into said actuated orientation.

Claim 14

The single use lancet device recited in claim 12 wherein said abutment structure comprises a shoulder element and a restrictor panel, said restrictor panel and said shoulder element structured to pass one another upon said actuation assembly moving from said un-actuated orientation to said actuated orientation, and to abut one another upon attempted movement of said actuation assembly into said un-actuated orientation after movement into said actuated orientation.

Claim 15

The single use lancet device recited in claim 13 wherein said shoulder element includes an at least partially biased configuration structured to at least partially retract to facilitate passage of said restrictor panel and said shoulder element past one another in a first direction corresponding movement of said actuation assembly into said actuated orientation from said un-actuated orientation, and to expand subsequent said passage past one another in said first direction such that said shoulder element and said restrictor panel abut one another upon movement towards one another in a second direction generally opposite said first direction.

Claim 16

The single use lancet device recited in claim 13 wherein said shoulder element is defined on said release element of said actuation assembly lancet, and said restrictor panel is defined in said housing.

Claim 17

The single use lancet device recited in claim 1 wherein said driving assembly includes a biasing element operatively disposed between said lancet and said housing.

Claim 18

The single use lancet device recited in claim 16 wherein said biasing element comprises a spring.

Claim 19

A single use lancet device comprising: a) a housing; b) a lancet, said lancet including a piercing tip; c) said lancet movably disposed in said housing and structured to move at least between a cocked orientation and a piercing orientation; d) a driving assembly structured to move said lancet at least temporarily into said piercing orientation; e) a retention member and an engagement hub, said engagement hub structured to be cooperatively engaged with said retention member at least upon said lancet being disposed in said cocked orientation so as to maintain said lancet in said cocked orientation until said retention member and said engagement hub are released from said cooperative engagement with one another; f) an actuation assembly structured to move between an actuated and an un-actuated orientation, movement of said actuation assembly into said actuated orientation structured to release said retention member and said engagement hub from said cooperative engagement with one another and thereby result in movement of said lancet into said piercing orientation; g) a restrictor assembly structured to substantially prevent said actuation assembly from moving out of said actuated orientation at least after said lancet has moved at least temporarily into said piercing orientation; and h) said restrictor assembly includes an abutment structure cooperatively disposed between said housing and said actuation assembly, and structured to prevent said actuation assembly from moving into said un-actuated orientation after movement into said actuated orientation.

Claim 20

A single use lancet device comprising: a) a housing; b) a lancet, said lancet including a piercing tip; c) said lancet movably disposed in said housing and structured to move at least between a cocked orientation and a piercing orientation; d) a driving assembly structured to move said lancet at least temporarily into said piercing orientation; e) a retention member and an engagement hub, said engagement hub structured to be cooperatively engaged with said retention member at least upon said lancet being disposed in said cocked orientation so as to maintain said lancet in said cocked orientation until said retention member and said engagement hub are released from said cooperative engagement with one another; f) an actuation assembly structured to move between an actuated and an un-actuated orientation, movement of said actuation assembly into said actuated orientation structured to release said retention member and said engagement hub from said cooperative engagement with one another and thereby result in movement of said lancet into said piercing orientation; g) a restrictor assembly structured to substantially prevent said actuation assembly from moving out of said actuated orientation at least after said lancet has moved at least temporarily into said piercing orientation; and h) said restrictor assembly includes an abutment structure cooperatively disposed between said housing and said actuation assembly, and structured to prevent said actuation assembly from moving into said un-actuated orientation after movement into said actuated orientation.
