Abstract

A biochemical test strip is provided. The biochemical test strip includes an insulating substrate, an electrode system, an insulating layer, and a cover. The electrode system is formed on the insulating substrate and the insulating layer is formed on the electrode system. The insulating layer has an opening, and the opening exposes a part of the electrode system to define a reaction region with a supply port. The cover is formed above the insulating layer to cover the reaction region and has a slot corresponding to the reaction region and a sampling hole corresponding to the supply port.

Claims

1. A biochemical test strip, comprising:

an insulating substrate;

an electrode system disposed on the insulating substrate;

an insulating layer disposed on the electrode system, the insulating layer having a first opening to expose a part of the electrode system to define a reaction region with a supply port; and

a cover disposed on the insulating layer to cover the reaction region, the cover having a slot corresponding to the reaction region and a sampling hole corresponding to the supply port.

2. The biochemical test strip of claim 1, wherein the slot is shaped as a straight line, an arc, a cross, or a concave shape.

3. The biochemical test strip of claim 2, wherein the slot is shaped as a straight line and is perpendicular to the supply port.

4. The biochemical test strip of claim 2, wherein the slot is shaped as a straight line and is horizontal to the supply port.

5. The biochemical test strip of claim 2, wherein the slot is shaped as a straight line and is in a slanting position, rather than horizontal or perpendicular, relative to the supply port.

6. The biochemical test strip of claim 1, wherein the slot has a width ranged between 0 mm and 1 mm.

7. The biochemical test strip of claim 6, wherein the reaction region has a width less than 2 mm and a length less than 8 mm.

8. The biochemical test strip of claim 7, wherein the width of the reaction region is 1.4 mm, the length of the reaction region is 4 mm, and the width of the slot is between 0.01 mm and 0.5 mm.

9. The biochemical test strip of claim 2, wherein the slot is shaped as a cross including an r angle and a curving degree of the r angle depends upon a tangent line segment defined by a plotting system.

10. The biochemical test strip of claim 9, wherein the tangent line segment is ranged between 0.05 mm and 0.5 mm.

11. The biochemical test strip of claim 9, wherein the tangent line segment is 0.2 mm.

12. The biochemical test strip of claim 1, wherein a length of the slot is larger than a width of the reaction region.

13. The biochemical test strip of claim 1, wherein the supply port is located at a side of the reaction region, and the reaction region further comprises another side corresponding to the slot and away from the supply port.

14. The biochemical test strip of claim 1, wherein the slot comprises a part corresponding to the reaction region and another part not corresponding to the reaction region.

15. The biochemical test strip of claim 1, wherein the insulating layer has a thickness ranged between 0.005 mm and 0.3 mm.
