Abstract

An adjustable endcap for a lancing device includes a basecap and a twistcap. The basecap includes a post with detents thereon. At least one finger is provided on the basecap adjacent the post. The twistcap includes at least one helical track on its outer surface into which the finger extends when the twistcap is mounted on the post. The twistcap also includes a plurality of grooves on an inner surface for engagement with the detents. As the twistcap is rotated on the post, the interaction of the finger and track causes the twistcap to move toward and away from the basecap and to adjust the penetration depth of a lance reciprocally mounted in the lancing device.

Claims

1. An adjustable endcap for a lancing device, comprising:

a basecap, and

a twistcap,

said basecap including a post member and at least one finger on said basecap adjacent said post member,

said twistcap adapted to fit over said post member, said twistcap including at least one generally helical track on an outer surface thereof, said finger extending into said track when said twistcap is on said post member.

2. The adjustable endcap claimed in claim 1 comprising at least one cantilevered detent on said post member, and at least one detent receiving surface on an interior surface of said twistcap.

3. The adjustable endcap claimed in claim 1 wherein said basecap is configured to fit on a lancing device.

4. The adjustable endcap claimed in claim 1 wherein said post member is cylindrical.

5. The adjustable endcap claimed in claim 1 wherein said basecap further comprises a second finger adjacent said post and said twistcap further comprises a second generally helical track on an outer surface thereof, said second finger extending into said second track when said twistcap is on said post member.

6. An adjustable endcap for a lancing device, comprising:

a basecap configured to be mounted on a lancing device, said basecap including a cylindrical post member with a first cantilevered detent thereon, said basecap further including a first finger adjacent to and extending radially toward said cylindrical post member; and

a twistcap configured to fit on said cylindrical post member, a first generally helical track on an outer surface of said twistcap oriented to be aligned with said first finger when said twistcap is on said cylindrical post member, a plurality of detent receiving surfaces on an interior surface of said twistcap.

7. The adjustable endcap for a lancing device claimed in claim 6 wherein said basecap further includes a second cantilevered detent on said cylindrical post member.

8. The adjustable endcap for a lancing device claimed in claim 6 wherein said basecap further includes a second finger adjacent to and extending radially toward said cylindrical post member.

9. The adjustable endcap for a lancing device claimed in claim 6 wherein the twistcap further includes a second generally helical track on said outer surface of said twistcap.

10. An endcap for adjusting the penetration depth of a lance of a lancing device, comprising:

a basecap including a cylindrical mounting post, first and second cantilevered detents on diametrically opposed sides of said mounting post, first and second fingers on said basecap adjacent to and on opposite sides of said mounting post; and

a twistcap rotatably mounted on said mounting post, a plurality of detent receiving grooves on an interior surface of said twistcap, and first and second generally helical tracks formed on an outer surface of said twistcap aligned with said first and second fingers, respectively.
