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 extending between a forward end and a rearward end, the rearward end including a rearward finger grip indentation having a concave surface curving in the forward end direction, the housing further comprising a first lateral side including a first lateral concave finger grip indentation, an opposing second lateral side including a second lateral concave finger grip indentation, a first rearward convex surface extending between the rearward concave finger grip indentation and the first lateral concave finger grip indentation, and a second rearward convex surface extending between the rearward concave finger grip indentation and the second lateral concave finger grip indentation;

a shield extending from the forward end of the housing and coaxially and movably associated with the housing, the shield including a plurality of peripheral indentations; and

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

wherein axial pressure applied in the forward end direction by a user against a surface moves the housing and the shield axially 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; and

wherein the second position provides an input movement to activate an actuation mechanism for releasing the lancet.

2. The lancet device of claim 1, wherein axial pressure applied by the user against at least one of the rearward concave finger grip indentation or the first or the second lateral concave finger grip indentation moves the housing and the shield axially 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.

3. The lancet device of claim 1, wherein the first and the second lateral concave finger grip indentations are respectively formed within a convex shape of the first lateral side and the second lateral side.

4. The lancet device of claim 1, wherein the first and the second lateral concave finger grip indentations respectively on the first lateral side and the second lateral side of the housing are defined by a radial curve positioned within a convex shape extending between the forward end and the rearward end.

5. The lancet device of claim 1, wherein the housing further includes two opposed sides in addition to and adjacent the two opposing first and second lateral sides, the two opposed sides being generally convex shaped between the forward end and the rearward end of the housing.

6. The lancet device of claim 5, wherein the housing forms an elliptical shaped housing.

7. The lancet device of claim 1, wherein the forward end of the housing includes a forward concave finger grip indentation.

8. The lancet device of claim 7, further comprising a removable tab member for maintaining sterility of the lancet device, the removable tab member including a surface corresponding with the forward concave finger grip indentation of the housing.

9. The lancet device of claim 1, wherein the housing further comprises at least one trough extending along at least a portion of at least one of the opposing first and second lateral sides.

10. The lancet device of claim 1, wherein the housing further comprises a plurality of longitudinal ribs extending along at least a portion of at least one of the opposing first and second lateral sides.

11. The lancet device of claim 10, wherein the plurality of longitudinal ribs form the first or the second lateral concave finger grip indentation on at least one of the opposing first and second lateral sides.

12. The lancet device of claim 11, wherein the plurality of longitudinal ribs are axially discontinuous along at least one of the opposing first and second lateral sides.

13. The lancet device of claim 10, wherein the plurality of longitudinal ribs form the first and the second lateral concave finger grip indentations respectively on the first lateral side and the second lateral side.

14. The lancet device of claim 10, wherein a portion of the plurality of longitudinal ribs forms a generally concave surface between a forward convex surface of the plurality of longitudinal ribs adjacent the forward end and a rearward convex surface of the plurality of longitudinal ribs adjacent the rearward end.

15. The lancet device of claim 1, wherein the plurality of peripheral indentations of the shield are adapted to visually indicate an alignment position of a puncturing element disposed within the lancet device.

16. The lancet device of claim 1, wherein the peripheral indentations are generally U-shaped concave depressions.
