Abstract

An article suitable for conducting one or more assays with an apparatus, e.g., a meter, for determining the presence or concentration of an analyte in a sample of biological fluid. The article contains a plurality of biosensors arranged in such a manner that each of the biosensors can be utilized before the article must be removed from the apparatus.

Claims

1. An article for providing a plurality of test strips, said article comprising:

(a) a plurality of segments, each of said segments having a first end and a second end and attached to at least one other segment, said segments arranged in a line;

(b) each segment comprising an aperture at the first end, wherein at least a portion of the aperture is in fluid communication with a sample chamber and a notch at a sample receiving end of the aperture;

(c) each segment having a recess on one major surface thereof comprising a test strip having an electrode arrangement, and

(d) each segment having at least a first slot at the second end for moving said segment linearly for enhancement of collecting a sample of biological fluid emerging from an opening in the skin of a patient.

2. The article of claim 1, wherein each segment has at least a second slot for indexing said segment when a test strip supported by said segment has been used.

3. The article of claim 2, wherein the second slot is at the second end of each segment.

4. The article of claim 1, wherein each segment comprises an opening for exposing said electrode arrangement at the second end of each segment.

5. The article of claim 1, wherein each notch of each segment faces at least one other segment.

6. The article of claim 1, wherein said segments are separated from adjacent segments by perforations or score lines.

7. The article of claim 1, wherein said segments are detachably attached by rupturable links, whereby a given segment can be detached from an adjacent segment.

8. The article of claim 1, wherein said segments are detachably attached by links, each of said links comprising a pin and a pin holder, said pin capable of being removed from its respective pin holder.

9. The article of claim 1, wherein said segments are arranged in a fan-fold configuration, in which the segments resemble the folds of a fan or the pleated bellows of an accordion.

10. The article of claim 1, wherein said segments are arranged in a round track configuration which resembles a roll.

11. The article of claim 1, wherein said segments are arranged in an L-shaped configuration, in which the segments do not form a closed loop.

12. The article of claim 1, wherein each of said segments has a channel formed therein to allow for the flow of a liquid sample.

13. The article of claim 12, wherein one end of the channel is adjacent to the aperture to enable transfer of biological fluid from the subject to the channel.

14. The article of claim 12, wherein one end of the channel terminates at a vent opening or a physical end of the channel or at a flow-terminating interface.

15. The article of claim 12, wherein the channel comprises a surfactant-coated mesh to aid the wicking of the sample.

16. The article of claim 12, wherein the channel comprises a reaction site.
