Abstract

The present invention provides a biosensing device, comprising an input unit, an analysis unit, a process unit, and a set unit, to set up the calibration parameters of a strip in the device so that the calibration can be completed at a lower cost and be more user friendly.

Claims

1. A biosensing device comprising the following units:

an input unit comprising a parameter-setting card of a strip and a port of the biosensing device wherein the parameter-setting card connects with the port so that the circuit of the card and the signal-acquiring circuit of the biosensor device form a working circuit and produce an electrical signal by providing the circuit on the card with a voltage or a current;

an analysis unit converting the resulting signal through an analog-to-digital converter (ADC) circuit;

a process unit decoding the electrical signal obtained from the analysis unit to obtain the data values by pre-defining the maximum value (P_max), minimum value (P_min) and the resolution value (P_res) to be entered into the biosensing device and determining the minimum unit of measurement (step) from the maximum value (U_max) and minimum value (U_min) of the characterizing method; and

a set unit storing the resulting data numbers as the basis for calibrating the biosensing device for the strip.

2. The biosensing device according to claim 1, wherein the voltage or current that provides the circuit of the card is a DC (direct current) electric source.

3. The biosensing device according to claim 1, wherein the electric source is built into the biosensing device.

4. The biosensing device according to claim 1, wherein the electrical signal is characterized by a voltage difference, time difference, or a combination of the two.

5. The biosensing device according to claim 1, wherein the parameter-setting card comprises a circuit comprised of at least a set of non-memory elements.

6. The biosensing device according to claim 5, wherein the circuit is the circuit comprised of resistors, capacitors, an inductor, or a combination of the three in series or parallel configurations.

7. The biosensing device according to claim 1, wherein, by using voltage difference as the featuring method, the data numbers can be obtained through the following equation or its relationship by using the voltage difference to characterize the electrical signal:

$P_n=\frac{P_{\max }-P_{\min }}{P_{\mathrm{res}}}$

8. The biosensing device according to claim 1, wherein the maximum value and the minimum value of the characterizing method to be used are determined by obtaining the minimum unit of measurement (step) through the following equation or its relationship:

$\mathrm{step}=\frac{U_{\max }-U_{\min }}{P_n}$

9. The biosensing device according to claim 1, wherein the data values can be calculated through the following equation or its relationship:

$P=P_{\min }+\frac{U_{\mathrm{in}}}{\mathrm{step}}$

wherein the P_min and step are defined in claim 1 and U_in is the characterized value of signal.
