Abstract

A method for lancing a dermal tissue target site includes contacting a distal compression surface of a ring-shaped cap body of a dermal tissue lancing device cap with the dermal tissue target site. Subsequently, the dermal tissue lancing device cap is urged towards the dermal tissue target site such that a force is exerted on the distal compression surface that results in the ring-shaped cap body revolving while remaining securely engaged within a retainer of the dermal tissue lancing device cap. The dermal tissue target site is thereafter lanced with the dermal tissue lancing device.

Claims

1. A method for lancing a dermal tissue target site, the method comprising:

contacting a distal compression surface of a ring-shaped cap body of a dermal tissue lancing device cap with the dermal tissue target site;

urging the dermal tissue lancing device cap towards the dermal tissue target site such that a force is exerted on the distal compression surface that results in the ring-shaped cap body revolving while remaining securely engaged within a retainer of the dermal tissue lancing device cap; and

lancing the dermal tissue target site with the dermal tissue lancing device.

2. The method of claim 1, wherein the revolution of the ring-shaped cap body during the urging step serves to form a dermal tissue target site bulge within an opening of the dermal tissue lancing device cap.

3. The method of claim 1 further including the step of continuing to urge the dermal tissue lancing device cap towards the dermal tissue target site following the lancing step.

4. The method of claim 3, wherein the continuing to urge step occurs for a time period in the range of 2 seconds to 12 seconds.

5. The method of claim 1, wherein the urging step continues for a time period in the range of 1 seconds to 8 seconds prior to the lancing step.

6. The method of claim 1, wherein the urging step is such that the force is a torsional force.

7. The method of claim 1, wherein the contacting step includes contacting a distal compression surface of a ring-shaped segmented cap body with the dermal tissue target site.

8. The method of claim 7, wherein the urging step results in cap body segments of the ring-shaped segmented cap body revolving.

9. The method of claim 1, wherein the contacting step includes contacting a distal compression surface of a ring-shaped deformable cap body with the dermal tissue target site.

10. The method of claim 1, wherein the contacting step includes contacting a distal compression surface of a ring-shaped deformable cap body that includes slits with the dermal tissue target site.
