Abstract

A lancet device used to pierce a user'"'"'s skin and including a lancet with a body portion and a piercing tip, a primary housing, a cover assembly with a piercing opening and structured to be matingly coupled with the primary housing to define an interior chamber, and a lancet receiving assembly movably disposed within the interior chamber and structured and disposed to hold the lancet during its driven movement between a cocked orientation, a piercing orientation and a fired orientation. The lancet device further includes a retention member including a pair of elongate fingers, and an engagement hub disposed in the interior chamber and structured to be cooperatively engaged by inwardly depending protrusions on the elongate fingers when the lancet receiving assembly is in the cocked orientation so as to maintain the lancet receiving assembly in the cocked orientation until the retention member is affirmatively released from its cooperative engagement with the engagement hub by an exteriorly actuatable actuation assembly which urges the elongate fingers out of their engagement with cooperative structure on the engagement hub. Moreover, a removable extension segment is preferably provided so as to increase an overall length of the lancet device as desired by a user.

Claims

1. A lancet device comprising:

a lancet, said lancet including a piercing tip,

a primary housing,

a lancet receiving assembly,

said lancet receiving assembly structured to at least temporarily move said lancet into a piercing orientation,

a cocking assembly structured to maintain said lancet receiving assembly at least temporarily in a cocked orientation,

an actuation assembly structured and disposed to release said lancet receiving assembly from said cocked orientation,

a removable extension segment structured to selectively and operatively extend a length of the lancet device so as to increase a manipulability thereof.

2. A lancet device as recited in

claim 1

wherein said extension segment is structured to be operatively coupled with said lancet receiving assembly and is movable therewith.

3. A lancet device as recited in

claim 2

wherein said extension segment includes a moveable element, said moveable element including a distal end and a proximal end, said distal end structured to be coupled with said lancet receiving assembly and said proximal end structured to at least temporarily engage said lancet.

4. A lancet device as recited in

claim 3

wherein said extension segment further includes an extension housing structured to be coupled with said primary housing, said extension housing structured to movably contain said moveable element.

5. A lancet device as recited in

claim 4

further comprising a cover assembly structured to be matingly coupled with said primary housing so as to define an interior chamber, said cover including a piercing opening where through said piercing tip of said lancet may at least temporarily extends.

6. A lancet device as recited in

claim 5

wherein said extension housing is further structured to receive said cover assembly operably coupled thereto and said moveable element is structured to at least temporarily extend said piercing tip of said lancet through said piercing opening of said cover assembly.

7. A lancet device as recited in

claim 4

wherein said extension segment further includes a restriction assembly structured to maintain said moveable element movably coupled to said extension housing.

8. A lancet device comprising:

a lancet, said lancet including a piercing tip,

a primary housing,

a lancet receiving assembly disposed at least partially within said primary housing and structured to at least temporarily move said lancet into a piercing orientation,

a removable extension segment structured to selectively extend a length of the lancet device so as to increase a manipulability thereof, said extension segment structured to be operatively coupled with said lancet receiving assembly and being movable therewith,

said extension segment structured to at least temporarily engage said lancet upon being operatively coupled with said lancet receiving assembly,

said lancet receiving assembly structured to be retained in said cocked orientation,

an actuation assembly structured and disposed to release said lancet receiving assembly from said cocked orientation so as to result in driven movement of said extension segment and said lancet.

9. A lancet device as recited in

claim 8

wherein said extension segment includes a moveable element, said moveable element including a distal end and a proximal end, said distal end structured to be coupled with said lancet receiving assembly and said proximal end structured to engage said lancet.

10. A lancet device as recited in

claim 9

wherein said extension segment further comprises a biased return element operably engaged with said moveable element and structured to withdraw said moveable element and accordingly said piercing tip from said piercing orientation into a fired orientation.

11. A lancet device as recited in

claim 9

wherein said extension segment further includes an extension housing structured to be coupled with said primary housing, said extension housing structured to movably contain said moveable element.

12. To be used with a lancet device of the type including a lancet, a primary housing, and a lancet receiving assembly structured to at least temporarily move the lancet into a piercing orientation, a lancet extension segment comprising:

a moveable element, said moveable element including a distal end and a proximal end,

said distal end of said moveable element structured to engage said lancet receiving assembly,

said proximal end of said moveable element structured to at least temporarily engage said lancet;

said moveable element structured to move with the lancet receiving assembly to result in driven movement of said lancet at least temporarily into a piercing orientation,

an extension housing structured to be removably coupled with the primary housing and to movably contain said moveable element so as to selectively extend a length of the lancet device and increase a manipulability thereof.

13. A lancet device comprising:

a lancet, said lancet including a piercing tip,

a primary housing,

a lancet receiving assembly movably disposed within said primary housing and structured to at least temporarily move said lancet into a piercing orientation,

said lancet receiving assembly including a cocked orientation,

an actuation assembly structured and disposed to release said lancet receiving assembly from said cocked orientation,

said actuation assembly including an actuation head structured to be engaged by a user;

a cocking assembly structured to extend into said primary housing and to selectively move said lancet receiving assembly into said cocked orientation, and

said cocking assembly including an exterior head disposed in at least partially surrounding relation to said actuation head of said actuation assembly, said actuation assembly structured and disposed to permit actuating access to said actuation head upon said lancet receiving assembly being disposed in said cocked orientation.

14. A lancet device as recited in

claim 13

wherein said actuation assembly is structured and disposed to protrude said actuation head from said exterior head of said cocking assembly upon said lancet receiving assembly being disposed in said cocked orientation, and to generally conceal said actuation head at least even with a plane of said exterior head of said cocking assembly when said lancet receiving assembly is released from said cocked orientation, thereby providing a tactile indication that said lancet receiving assembly is disposed in said cocked orientation.

15. A lancet device comprising:

a lancet, said lancet including a piercing tip,

a primary housing;

a lancet receiving assembly movably disposed within said primary housing and structured to at least temporarily move said lancet into a piercing orientation;

said lancet receiving assembly including a cocked orientation,

an actuation assembly structured and disposed to release said lancet receiving assembly from said cocked orientation so as to result in movement of said piercing tip of said lancet into said piercing orientation, and

said primary housing includes a generally triangular configuration so as to facilitate gripping thereof and so as to prevent rolling thereof when disposed on a flat surface.
