Collection well for body fluid tester
First Claim
1. An apparatus for use with a test strip and for collecting a body fluid for testing for an analyte contained within said body fluid, paid apparatus comprising:
- a reservoir for receiving and collecting a flow of body fluid from a discharge end of a conduit; and
a test strip opposing surface for contacting a surface of said test strip wherein, when said test strip is in contact with said test strip opposing surface, a capillary test space is formed there between wherein said capillary test space is positioned to be in fluid communication with said reservoir and sized to wick a transfer volume of said body fluid from raid reservoir when said fluid in said reservoir attains said transfer volume.

Abstract
A body fluid is collected for testing for an analyte contained within the body fluid. The fluid is collected in an apparatus including a reservoir for receiving and collecting a flow of body fluid from a discharge end of a conduit. A capillary test space is in fluid flow communication with the reservoir. The capillary test space is positioned to be in contact with the fluid in the reservoir after the fluid has accumulated to a predetermined transfer volume of fluid. The capillary test space is sized to wick the fluid from the reservoir when the fluid contacts the capillary test space.

11. The apparatus of claim 10 wherein a volume of said reservoir between said first and second ends of said reservoir is sized to at least as great as said transfer volume.
-
12. The apparatus of claim 1 wherein said reservoir has a size and geometry providing a surface tension which assures said fluid is retained within said reservoir.
-
13. The apparatus of claim 1 further comprising an enlarged volume adjacent said reservoir wherein said enlarged volume is greater than the volume of said reservoir.
-
14. The apparatus of claim 13 wherein said enlarged volume is defined by a hydrophobic material.
-
15. The apparatus of claim 1 further comprising a groove comprising a shape corresponding to the outer periphery of the test strip.
