Abstract

A lancet device generally includes a housing having opposing lateral sides extending between a forward end and a rearward end, and a shield coaxially and movably associated with the housing. The housing includes a plurality of longitudinal ribs extending along a portion of at least one of the opposing lateral sides. The plurality of longitudinal ribs form a finger grip on at least one of, and typically both of the opposing lateral sides. The shield is generally movable from a first position in which the shield extends outwardly from the forward end of the housing to a second position in which the shield is at least partially moved within the housing, based on axial pressure applied by the user against the finger grip formed by the longitudinal ribs.

Claims

1. A lancet device, comprising:

a housing comprising opposing lateral sides extending between a forward end and a rearward end, the housing further comprising a plurality of longitudinal ribs extending along a portion of at least one of the opposing lateral sides, the plurality of longitudinal ribs forming a finger grip on the at least one of the opposing lateral sides; and

a shield coaxially and movably associated with the housing such that axial pressure applied by the user against the finger grip moves the housing and the shield with respect to each other from a first position in which the shield extends outwardly from the forward end of the housing to a second position in which the shield is at least partially moved within the housing.

2. The lancet device of claim 1, wherein the longitudinal ribs extend along a portion of both of the opposing lateral sides of the housing forming finger grips on both of the opposing lateral sides.

3. The lancet device of claim 1, wherein a portion of each of the longitudinal ribs is contoured to form the finger grip as a generally concave surface.

4. The lancet device of claim 3, wherein another portion of the longitudinal ribs is contoured to form a generally convex surface.

5. The lancet device of claim 4, wherein the longitudinal ribs are contoured to generally form a forward convex surface at a portion of the opposing lateral side adjacent the forward end and a rearward convex surface at a portion of the opposing lateral side adjacent the rearward end of the housing, with the generally concave surface formed between the forward and the rearward convex surfaces.

6. The lancet device of claim 5, wherein the longitudinal ribs forming the forward and the rearward convex surfaces are aligned through the concave surface to form the finger grip as an indentation on at least of the opposing lateral sides of the housing.

7. The lancet device of claim 5, wherein the longitudinal ribs form a generally oval concave surface.

8. The lancet device of claim 1, wherein the housing further comprises a finger grip indentation formed on the rearward end of the housing for accommodating a user'"'"'s finger during use of the lancet device.

9. The lancet device of claim 8, wherein the finger grip indentation formed on the rearward end of the housing is concave.

10. The lancet device of claim 1, wherein the shield defines a plurality of peripherally spaced indentations for visually indicating an alignment position of a puncturing element disposed within the housing and/or the shield.

11. A lancet device, comprising:

a housing extending between a forward end and a rearward end;

a shield extending coaxially through the forward end of the housing and movably associated with the housing;

a lancet assembly disposed in the housing and adapted to extend through an opening in a forward end of the shield upon movement of the shield with respect to the housing; and

a removable tab member having an inner portion maintaining sterility of a lance tip of the lancet assembly and an outer portion enclosing the opening in the forward end of the shield and adapted to maintain the shield and the housing from axially moving with respect to each other.

12. The lancet device of claim 11, wherein the inner portion of the tab member comprises a post substantially enclosing the lance tip, and the outer portion of the tab member further comprises a grip portion adapted to be grasped by the user.

13. The lancet device of claim 12, wherein the outer portion of the tab member comprises a depending skirt formed to engage an external surface of the forward end of the shield extending from the forward end of the housing.

14. The lancet device of claim 13, wherein the depending skirt includes structure for cam-like engagement with the forward end of the housing to facilitate removal of the tab member.

15. The lancet device of claim 12, wherein the grip portion comprises a paddle-shaped member for grasping by the user.

16. The lancet device of claim 15, wherein opposed longitudinal edges of the paddle-shaped member are oppositely curved such that opposed sides of the paddle-shaped member define contouring to indicate to a user a rotational direction for rotating the tab member to assist in removing the tab member.

17. The lancet device of claim 16, wherein a transverse cross-section through the paddle-shaped member defines a general wave or S-shape.

18. The lancet device of claim 15, wherein the paddle-shaped member is generally oval-shaped.

19. The lancet device of claim 15, wherein opposed sides of the paddle-shaped member are concave.

20. The lancet device of claim 15, wherein opposed sides of the paddle-shaped member include at least one raised grip tab thereon.

21. The lancet device of claim 15, wherein opposed edges of the paddle-shaped member define opposed longitudinal curved portions.

22. The lancet device of claim 21, wherein the opposed longitudinal curved portions are generally elliptical shaped.

23. The lancet device of claim 21, wherein at least one shaped indentation is defined in at least one side of the paddle-shaped member.

24. The lancet device of claim 23, wherein the shaped indentation is polygonal shaped.

25. The lancet device of claim 12, wherein the grip portion defines opposed finger grip indentations for grasping by the user.

26. The lancet device of claim 25, wherein the finger grip indentations are concave.

27. The lancet device of claim 25, wherein the grip portion comprises an intermediate portion adjacent the post portion and grip portion, the intermediate portion defining a helical texture.

28. The lancet device of claim 25, wherein the finger grip indentations each include at least one raised grip tab.

29. The lancet device of claim 12, wherein the grip portion is detachable from the post.
