Abstract

A medical diagnostic test strip is disclosed, which comprises: a top plate, having at least a cell arranged therein for storing an enzyme, each cell having at least a microchannel channeling out to the outer rim of the top plate therefrom while enabling one of the plural microchannel to guide in an analyte by siphoning; and a bottom plate, capable of being coupled correspondingly to the top plate, having at least a conductive wire, being arranged and extending from a position of the bottom plate corresponding to each cell while keeping each conductive wire from contacting the enzyme.

Claims

1. A medical diagnostic test strip, comprising:

a top plate, having at least a cell arranged therein for storing one of a plurality of enzymes, each cell having at least a microchannel channeling out to the outer rim of the top plate therefrom while enabling one of the plural microchannel to guide in an analyte by siphoning; and

a bottom plate, capable of being coupled correspondingly to the top plate, having at least a conductive wire, being arranged at and extending from a position of the bottom plate corresponding to each cell of the top plate while keeping each conductive wire from contacting the enzyme.

2. The test strip of claim 1, wherein the plural enzymes are being arranged in their corresponding cells respectively during the manufacturing of the top plate.

3. The test strip of claim 1, wherein each cell has a first via hole arranged at the bottom thereof and each first via hole is connected to a second via hole arranged at a position of the bottom plate corresponding therewith, thereby a conduit is formed for guiding the mixture of the analyte and the corresponding enzyme from the top plate to the bottom plate.

4. The test strip of claim 1, wherein at least a side of the top plate has at least one conductive wire arranged thereon.

5. The test strip of claim 1, wherein at least a side of the bottom plate has at least one conductive wire arranged thereon.

6. The test strip of claim 1, wherein the conductive wire is made of a material selected from the group consisting of carbon nano tube (CNT) and metal particles.

7. The test strip of claim 1, wherein the top plate and the bottom plate are formed respectively by a substrate selected from the group consisting of paper and plastic.

8. The test strip of claim 1, wherein the top plate has at least a microchannel and at least a cell, all being integrally formed thereon by a simple press molding process utilizing a die.

9. The test strip of claim 1, wherein a breach is arranged on each microchannel at a position thereof in the vicinity of the outer rim of the top plate for breaking the surface tension of the liquid-state analyte and thus helping the guiding of the analyte into each cell.

10. The test strip of claim 8, wherein a breach is arranged on each microchannel at a position thereof in the vicinity of the outer rim of the top plate for breaking the surface tension of the liquid-state analyte and thus helping the guiding of the analyte into each cell.

12. The test strip of claim 7, wherein the plural enzymes are being arranged in their corresponding cells respectively during the manufacturing of the top plate.

20. The test strip of claim 8, wherein a breach is arranged on each microchannel at a position thereof in the vicinity of the outer rim of the top plate for breaking the surface tension of the liquid-state analyte and thus helping the guiding of the analyte into each cell.

11. A medical diagnostic test strip, comprising:

a top plate, having at least a cell arranged therein for storing one of a plurality of enzymes, each cell having at least a microchannel channeling out to the outer rim of the top plate therefrom while enabling one of the plural microchannel to guide in an analyte by siphoning;

a bottom plate, having a cell arranged therein for storing an enzyme, the cell having at least two microchannels channeling out to the outer rim of the bottom plate therefrom while enabling one of the plural microchannel to guide in the analyte by siphoning; and

a middle plate, capable of being coupled correspondingly to the top plate and the bottom in respective, having at least a conductive wire, being arranged and extending from a position of the middle plate corresponding to each cell of the top plate while keeping each conductive wire from contacting the enzyme thereof, and at least a conductive wire, being arranged and extending from a position of the middle plate corresponding to each cell of the bottom plate while keeping each conductive wire from contacting the enzyme thereof.

13. The test strip of claim 11, wherein each cell has a first via hole arranged at the bottom thereof and each first via hole is connected to a second via hole arranged at a position of the bottom plate corresponding therewith, thereby a conduit is formed for guiding the mixture of the analyte and the corresponding enzyme from the top plate to the bottom plate.

14. The test strip of claim 11, wherein at least a side of the top plate has at least one conductive wire arranged thereon.

15. The test strip of claim 11, wherein at least a side of the bottom plate has at least one conductive wire arranged thereon.

16. The test strip of claim 11, wherein the conductive wire is made of a material selected from the group consisting of carbon nano tube (CNT) and metal particles.

17. The test strip of claim 11, wherein the top plate, the middle plate and the bottom plate are formed respectively by a substrate selected from the group consisting of paper and plastic.

18. The test strip of claim 11, wherein the top plate has at least a microchannel and at least a cell, all being integrally formed thereon by a simple press molding process utilizing a die, while the bottom plate has at least a microchannel and at least a cell, all being integrally formed thereon by a simple press molding process utilizing a die.

19. The test strip of claim 11, wherein a breach is arranged on each microchannel at a position thereof in the vicinity of the outer rim of the top plate for breaking the surface tension of the liquid-state analyte and thus helping the guiding of the analyte into each cell.
