Detection test piece, manufacture method thereof and detection apparatus

Abstract

The invention discloses a detection test piece, a manufacture method thereof and a detection apparatus. The detection test piece is used to detect the content of biochemical compositions in a detected sample, and comprises an insulating base plate, an electrode layer arranged on the insulating base plate, a reaction layer disposed on the electrode layer, and an amplification circuit formed on the insulating base plate; the electrode layer comprises an anode part and a cathode part; two ends of the anode part form a working electrode and an anode contact joint, and two ends of the cathode part respectively form a reference electrode and a cathode contact joint; the reaction layer is contacted with a detection body and generates a chemical reaction, and the reaction layer covers the working electrode and the reference electrode and is in connection individually with the working electrode and the reference electrode; and the amplification circuit is electrically coupled between the working electrode and the anode electrode, so as to amplify an electron signal generated by the chemical reaction and output by the working electrode. According to the detection test piece, the noise-to-signal ratio of the front end of the detection test piece is improved, an amplification circuit in a signal processing device of a detection apparatus is omitted, and the system configuration and the integral cost of the signal processing device of the detection apparatus are simplified.

Description

technical field [0001] The present invention relates to a detection test piece, a manufacturing method thereof, and a detection device, in particular to a detection test piece with an amplifying circuit, a manufacturing method thereof, and a detection device having the same. Background technique [0002] With the development of biological detection technology, some inspection items, such as biochemical, immune, and genetic tests, can only be obtained by specific places such as hospitals, testing rooms, laboratories, and with the help of precision instruments or medical professionals such as physicians, examiners, and researchers. At present, not only can it be carried out in clinics, but even patients can test themselves at home. This technology is called Point of care test (POCT). Common POCT biochemical test items include blood sugar, cholesterol, and uric acid, while immune test items include pregnancy, drug abuse, cancer indicators, glycosylated hemoglobin, and enterovir...

Problems solved by technology

Although increasing the amount of blood collected can increase the strength of the current signal, it also means that the blood collection needle needs to be pricked deeper, and it is more likely to cause discomfort to the user; increasing the amount of reagent means that the amount of enzyme or enzyme used will also increase. The cost of the chip will also rise accordingly; increasing the sensitivity of the sensor means that the analog-to-digital converter (Analog to Digital Converter, ADC) of the sensor requires a higher number of bits, and the production cost of the sensor will also increase accordingly.
