Abstract

The present invention provides a biosensor with finger-positioning function, comprising: a bottom plate, a cover, and a test-strip socket; wherein the cover mounted on the bottom plate has a front end provided with a guiding plate for positioning a finger, and the guiding plate has a center line and a guiding surface, in which the center line passes through a center of the guiding surface; and the test-strip socket is formed at the front end of the cover. When using the biosensor, the user can rest his/her wrist and palm on the cover of the biosensor and rest the punctured finger on the guiding surface provided at the front end of the cover to align the test strip with the blood drop on the finger so as to simplify the measurement.

Claims

1. A biosensor with finger-positioning alignment structure, comprising:

a bottom plate,

a cover, wherein the cover mounted on the bottom plate has a front end provided with a guiding plate having a guiding surface for positioning a finger, and the guiding plate has a center line, in which the center line passes through a center of the guiding surface; and

a test-strip socket, which is formed at the front end of the cover below the guiding surface to aid in structural alignment of a finger on the test-strip socket;

wherein a removable chassis is deposited below the test-strip socket.

2. The biosensor of claim 1, wherein the test-strip socket is formed on the center line of the guiding plate.

3. The biosensor of claim 1, wherein the guiding surface is inclined toward the test-strip socket.

4. The biosensor of claim 1, wherein the guiding plate at the front end of the cover has two opposite sides thereof formed as an aligning feature.

5. The biosensor of claim 4, wherein the aligning feature comprises two positioning blocks.

6. The biosensor of claim 5, wherein the positioning blocks comprises angled structures that are transversely symmetrical.

7. The biosensor of claim 1, wherein the cover further comprises a USB connecting port.

8. The biosensor of claim 1, wherein the guiding plate further comprises an audio output.

9. The biosensor of claim 1, wherein the guiding surface has a width ranging between 1 to 3 centimeters.

10. The biosensor of claim 9, wherein the guiding surface has a width of about 2 centimeters.

11. The biosensor of claim 10, wherein the guiding surface has a width of about 1.5 centimeters.
