Tape transport lance sampler
First Claim
1. A body fluid sampling device, comprising:
- a lancet including a lancet tip configured to lance tissue;
a protective cover covering at least a portion of the lancet tip; and
a tape coupled to the lancet and the protective cover, the tape having a slackened section between the lancet and the protective cover for allowing removal of the protective cover from the lancet tip when the tape is pulled, wherein the slackened section is longer than the distance between where the tape is coupled to the lancet and where the tape is coupled to the protective cover.

Abstract
A lancet-sampler system is configured to automatically remove a protective cover from a lancet and automatically unpack a test pad just prior to use. This minimizes the risk of injury and reduces the chance of cross-contamination between the lancet and the test pad. The lancet defines a capillary groove for drawing body fluid from the incision via capillary action and a sample transfer opening for collecting the fluid from the groove. A carrier tape is coupled to the lancet. The carrier tape includes a test pad for analyzing the fluid. The tape is folded around the test pad to form an airtight package. The test pad is located at a position to align with the sample transfer opening when the tape is unfolded. The protective cover covers a portion of the lancet, and when the tape is pulled, the protective cover is automatically pulled from the lancet.

21. A body fluid sampling device, comprising:
-
a lancet configured to lance an incision in tissue; and a carrier tape coupled to the lancet, wherein the lancet is attached to the carrier tape, the carrier tape including a test pad configured to analyze the body fluid, the tape being folded around the test pad, wherein the tape has a slackened section with the test pad that is located at a position to align with the lancet when the tape is unfolded. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. A body fluid sampling device, comprising:
-
a lancet including a lancet tip configured to lance tissue, a body located opposite the lancet tip, and the lancet defining a sample transfer opening that extends through opposing sides of the body, and a capillary groove that extends from the sample transfer opening to the lancet tip for transferring body fluid from the tissue to the sample transfer opening; a protective cover covering at least a portion of the lancet tip that lances the tissue; a test pad configured to analyze the body fluid; a tape having an intermediate section folded around the test pad to form a sealed packet that seals the test pad from exposure to the lancet and the outside environment, the tape being attached to the body of the lancet and the protective cover with the intermediate section having the sealed packet being located in between; the sealed packet being configured to unfolded when tension is applied to the tape; the intermediate section being longer that than the distance between the body and the lancet tip when the sealed packet is unfolded to allow the protective cover to pull away from the lancet tip; and the test pad being positioned on the intermediate section of the tape to align with the sample transfer opening when the sealed packet is unfolded for transferring the body fluid from the sample transfer opening onto the test pad. - View Dependent Claims (29, 30)
