Lancets for bodily fluid sampling supplied on a tape
First Claim
1. A method for obtaining a bodily fluid sample comprising:
- providing a reel-to-reel tape carrying a plurality of lancets, the lancets having lengths and being non-circular in cross section along a major portion of the lengths;
removing a sterile cover from a first lancet;
advancing the tape to position the first lancet adjacent a bend in the tape with a sharp tip of the first lancet spaced from the tape;
piercing tissue with the sharp tip of the first lancet;
after the piercing, advancing the tape to bring the sharp tip of the first lancet closer to the tape; and
after the advancing the tape to bring the sharp tip of the first lancet closer to the tape, covering and contacting the first lancet with the sterile cover.

Abstract
A supply of lancets for a multi-use lancing device are carried by a tape and sequentially brought from a storage position to an activating position by advancing the tape around a bend. The lancets are non-circular in cross-section along their longitudinal lengths, and in their activating position they extend from the tape such that their sharp tips are available for lancing tissue. The carrying tape can be arranged in reel-to-reel format in a housing having a lancing opening. The lancets can be integral with the tape and activated to move the lancet through the lancing opening by moving the tape along its tape path or by translating a dedicated service loop of the tape. The lancets can also be independent from the tape and activated through the lancing opening by a separate lancing actuator. A test media can be included on the carrying tape and the housing can contain a sensor to yield an integrated lancing and testing device.

8. A method for obtaining a bodily fluid sample comprising:
-
providing a reel-to-reel lancet tape carrying a plurality of lancets, the lancets having lengths and being non-circular in cross section along a major portion of the lengths and a cover tape positioned on the lancet tape; removing the cover tape from a first lancet with a take up reel configured to peel the cover tape away from the first lancet; advancing the lancet tape to position the first lancet adjacent a bend in the tape with a sharp tip of the first lancet spaced from the tape; piercing tissue with the sharp tip of the first lancet; after the piercing, advancing the tape to bring the sharp tip of the first lancet closer to the tape; and after the piercing, replacing the cover tape onto the first lancet with a reapplication reel.
