Abstract

There is provided a biosensor which includes: a substrate formed of an insulator; a set of electrodes provided on the substrate; a reaction part provided on the set of electrodes; a supply port for introducing blood (a specimen) to the reaction part; an attachment part for connecting the set of electrodes to a terminal of a measurement display; and a picking plate having a picking part to be picked up, the picking plate extending to a side opposite from the attachment part with respect to the reaction part and being bent in a cross-sectional direction perpendicular to the extending direction.

Claims

1. A biosensor for performing measurement by bringing a specimen, which is produced from and attached to an object from which a specimen is collected, into contact with a supply port, the biosensor comprising:

a substrate formed of an insulator;

a set of electrodes provided on the substrate;

a reaction part provided on the set of electrodes;

the supply port for introducing the specimen to the reaction part;

an attachment part for connecting the set of electrodes to a measurement display; and

a picking plate which extends to a side opposite from the attachment part with respect to the reaction part and has a picking part to be picked up or on which the picking part is formed.

2. The biosensor according to claim 1, wherein the picking plate is bent or curved in a cross-sectional direction.

3. The biosensor according to claim 1, wherein at least a part of the biosensor rises from a flat surface when being placed on the flat surface.

4. The biosensor according to claim 1, wherein the picking plate includes a fold-back line extending along a surface of the picking plate and is bent along the fold-back line.

5. The biosensor according to claim 4, wherein the supply port is located on a tip side of the picking plate relative to the fold-back line of the picking plate and is projected outward by bending the tip side of the picking plate along the fold-back line.

6. The biosensor according to claim 1, wherein the picking plate includes a through hole, into which the supply port is projected.

7. The biosensor according to claim 1, wherein a distance from the reaction part to a tip of the picking plate is longer than a distance from the reaction part to each end of the set of electrodes on an attachment part side.

8. The biosensor according to claim 1, further comprising a cover for covering the reaction part, wherein the picking plate is attached to the cover or the substrate.

9. The biosensor according to claim 1, wherein the set of electrodes are positioned between the substrate and the picking plate.

10. The biosensor according to claim 1, wherein the picking plate is engaged with an engaging member of the measurement display and is slid and detached from the measurement display by sliding the engaging member.

11. The biosensor according to claim 1, further comprising a position regulating system for regulating a position of the object from which a specimen is collected with respect to the supply port.

12. The biosensor according to claim 11, wherein the picking plate includes a through hole into which the supply port is projected and which constitutes the position regulating system.

13. The biosensor according to claim 12,

wherein the picking plate includes a fold-back line extending along a surface of the picking plate,

the supply port is projected outward by bending a tip side of the picking plate along the fold-back line, and

a peripheral part of the through hole forms a projected tip that is projected outward and constitutes the position regulating system.

14. The biosensor according to claim 13, wherein the supply port is located on a rear end side of the picking plate relative to the fold-back line of the picking plate and recedes to the rear end side relative to the projected tip by bending the tip side of the picking plate along the

15. The biosensor according to claim 11, comprising a cover for covering the reaction part, wherein the picking plate is attached to the cover or the substrate.

16. The biosensor according to claim 11, wherein the set of electrodes are positioned between the substrate and the picking plate.

17. The biosensor according to claim 15, wherein the set of electrodes are positioned between the substrate and the picking plate.
