Embodiment Construction

[0030] The foregoing and other technical content, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings. The directional terms mentioned in the following embodiments, for example: up, down, left, right, front or back, etc., are only directions for referring to the attached drawings. Therefore, the directional terms used are used to illustrate but not to limit the present invention.

[0031] An embodiment of the present invention provides a simple biosensor, sensing unit, and blood cell volume ratio measurement technology. The technology reduces the blood cell volume ratio by means of compensation, which is caused by general disposable biosensors. interference. The method is to first introduce the subject to be tested into a reaction cavity containing at least two reaction electrodes and reaction reagents through capillary suction. Then first apply a DC voltage for se...

Abstract

The invention discloses a biological sensor and a biological sensing method. The biological sensor is used for matching with a sensing unit, the sensing unit comprises a first electrode, a second electrode and a reaction cavity for accommodating a specimen to be measured, and the biological sensor is coupled with a direct-current voltage source and comprises a control unit and a converter; the converter is coupled with the direct-current voltage source, the first electrode and the second electrode; and the control unit controls the converter to make the first electrode and the second electrode apply a direct-current voltage to the specimen to be measured. The biological sensor and the biological sensing method can reduce or correct errors caused by a hematocrit.

Description

Technical field [0001] The present invention relates to a biological sensor and a biological sensing method, and in particular to a biological sensor and a biological sensing method that can be corrected according to the blood cell volume ratio. Background technique [0002] The detection principle of the general electrochemical sensing test piece is mainly to use the test object in the blood sample to react with the reagent on the test piece, and measure a current value of the test piece through a fixed voltage, and then use a conversion formula to Obtain the concentration of the analyte. However, such a single-voltage current-taking detection device is easily interfered by blood cells in the blood, which further affects the accuracy of the measurement. The blood cell volume ratio (HCT) has two effects on the whole blood test: (1) Change the viscosity of the blood, resulting in different efficiency of electron transfer, affecting the final measured current value; (2), causing d...
