Abstract

A cap for a lancing device includes a cap body and at least one sensor. In addition, the cap body includes a distal end with a target site contact surface, a proximal end for attachment to a lancing device and an opening through the cap body from the distal end to the proximal end. Furthermore, at least a portion of the target site contact surface is moveable between a first position and a second position upon application of a predetermined pressure to that portion of the distal end contact surface, and the sensor is configured to detect movement of the portion of the distal end contact surface into the second position and communicate such detection to the lancing device.

Claims

1. A cap for a lancing device comprising:

a cap body with

a distal end with a target site contact surface;

a proximal end for attachment to a lancing device;

a opening through the cap body from the distal end to the proximal end of thereof; and

at least one sensor,

wherein, at least a portion of the target site contact surface is moveable between a first position and a second position upon application of a predetermined pressure to the portion of the distal end contact surface, and

wherein the sensor is configured to detect movement of the portion of the distal end contact surface into the second position and communicate such detection to the lancing device.

2. The cap of claim 1, wherein the cap further includes a spring and the spring is configured to bias the portion of the target site contact surface that is moveable.

3. The cap of claim 1, wherein the cap body includes a moveable cap body portion and the portion of the target site contact surface that is moveable is a surface of the moveable cap body portion.

4. The cap of claim 3, wherein the moveable cap body portion moves from the first position to the second position within a guide recess of the cap body.

5. The cap of claim 4, wherein the moveable cap body portion is a nib disposed on the distal end of the cap body.

6. The cap of claim 1, wherein the sensor includes at least two electrical contacts and an electrical signal wire.

7. The cap of claim 1, wherein the cap includes a plurality of sensors uniformly distributed with respect to the cap body.

8. The cap of claim 1, wherein the portion of the target site contact surface extends above a remainder of the target site contact surface by a dimension in the range of 5 mm to 10 mm when in the first position.

9. The cap of claim 1, wherein the portion of the target site contact surface that is moveable represents a sector of the cap'"'"'s circumference in the range of 30 degrees to 180 degrees.

10. The cap of claim 1, wherein the predetermined pressure is the result of applying a force in the range of 2 Newton to 20 Newton.

11. The cap of claim 1, wherein the target site is a dermal tissue target of a user'"'"'s finger and the predetermined pressure is the result of applying a force in the range of 15 Newton to 18 Newton.

12. The cap of claim 1, wherein the cap body is configured for being urged against a dermal tissue target site of a user'"'"'s finger.
