Abstract

A fluid sensor comprises a formed plastic body and a reagent. The body has a top face with an integral first surface. The body also has a bottom face opposed to the first surface and a sidewall that extends from the periphery of the top face. The first surface is adapted to accept a fluid sample. The reagent is disposed on the integral first surface and causes a color change detectable on the bottom face when the reagent reacts with an analyte in the fluid sample.

Claims (21)

1. A sensor package, comprising:

a base portion having at least one conically shaped sensor cavity;

at least one test sensor, the at least one test sensor being located in the at least one conically shaped sensor cavity, the at least one test sensor including a formed plastic body and a reagent, the body having a top face with an integral first surface, a bottom face with a second surface opposed to the first surface, and a sidewall extending from the periphery of the top face, wherein the first surface is configured to accept a fluid sample, and the reagent being disposed on the integral first surface and configured to cause a color change detectable on the second surface when the reagent reacts with an analyte in the fluid sample; and

a protective sheet covering the at least one conically shaped sensor cavity.

2. The sensor package of claim 1 , wherein the at least one test sensor further comprises a surfactant disposed on the body.

3. The sensor package of claim 1 , wherein the at least one conically shaped sensor cavity is a plurality of conically shaped sensor cavities and the at least one test sensor is a plurality of test sensors, wherein each one of the plurality of test sensors is located in a respective one of the plurality of conically shaped sensor cavities.

4. The sensor package of claim 1 , wherein the formed plastic body is a hollow frustum with a larger open end and a smaller closed end.

5. The sensor package of claim 1 , wherein the top face has a raised region substantially surrounding the integral first surface.

6. The sensor package of claim 5 , further comprising a lid attached to the raised region.

7. The sensor package of claim 6 , wherein the lid is a rectangular plastic strip, the lid being attached to the raised region forming a plurality of vent openings.

8. The sensor package of claim 6 , wherein the lid is attached to the raised region and forms a capillary chamber.

9. The sensor package of claim 6 , wherein the lid is a hollow plastic frustum, having a large open end and a smaller closed end, the smaller closed end having a first surface with a plurality of vent holes.

10. The sensor package of claim 1 , wherein the top face is transparent.

11. The sensor package of claim 6 , wherein the top face is transparent or translucent, and the lid is opaque.

12. The sensor package of claim 3 , wherein each of the plurality of conically shaped sensor cavities is formed as a depression in the base portion of the sensor package.

13. The sensor package of claim 3 , wherein each of the plurality of conically shaped sensor cavities includes an inclined wall configured to position the respective one of the plurality of test sensors located therein in a predetermined position relative to an opening of each respective one of the plurality of conically shaped sensor cavities.

14. The sensor package of claim 3 , wherein the base further has a plurality of desiccant cavities, each one of the plurality of desiccant cavities being in fluid communication with a respective one of the plurality of conically shaped sensor cavities.

15. The sensor package of claim 3 , wherein the plurality of desiccant cavities and the plurality of conically shaped sensor cavities are aligned in rectangular arrays.

16. The sensor package of claim 1 , wherein the protective sheet is an aluminum burst foil.

17. The sensor package of claim 16 , wherein the at least one conically shaped sensor cavity is closed by heat-sealing the aluminum burst foil to a top surface of the base portion.

18. The sensor package of claim 17 , further comprising a conductive calibration label coupled to the base portion.
