Abstract

The utility model relates to a sensor of a biological sensor coupon and cooperation with identification function, which substantially comprises an insulating first and second base boards, wherein the first base board which is provided with electrodes and an identification electrodes area which is exposed outside the second base board is longer than the second base board, and the identification electrodes area comprises substantially a conducting material coating. The conducting material is provided with different impedance values to change according to different tests or different sensing equipments. When in use, the coupon is inserted into the sensor and can decide whether the impedance values in the sensor are within the limit through the impedance values generated by the conducting material of the identification electrodes area or the impedance values between the electrodes and the identification electrodes area, thereby the utility model can save more manufacturing cost and can be employed more conveniently without changing the cooperating sensor only by changing the impedance values according to needs when leaving factories.

Description

The sensor that has the biological sensor chip of recognition function and cooperate with it

Technical field

The sensor that the utility model relates to a kind of biological sensor chip and cooperates with it refers to a kind of sensor that has the biological sensor chip of recognition function and cooperate with it especially.

Background technology

Because the idea of nursing at home promotes day by day, fast, the house oneself's testing product that cheaply, does not need the professional to operate day by day increases, for example blood glucose meter, electronics ear thermometer, electronic type blood pressure meter etc., wherein the employed deserted blood sugar test paper of blood glucose meter promptly is to utilize the electrochemica biological sensor principle to detect blood sugar concentration in the corpse or other object for laboratory examination and chemical testing.

On market, be commonly used to test the sensor of blood sugar, cholesterol, Vetsin oxalic acid transferase (GOT), bran amine pyruvic acid transferase (GPT) etc. at present, because the volume of its test piece is little, it is also approximate to add its outward appearance, shape, therefore the consumer in use, the numerical fault that may misapply and cause this sensor to use or to be measured, for example desire detects blood glucose value, but misuse measures the generation of the situations such as test piece of cholesterol.

Take place for improving above-mentioned situation, please refer to shown in Fig. 1 a, 1b, the 1c, it is WO the 0171328th a patent case, and it mainly is that an electrochemica biological sensor test piece is disclosed, and it is the composition in quantitative test blood sugar, cholesterol and other blood selectively.One end of this electrochemica biological inductor test piece 50 is provided with as identification electrode 60, this identification electrode 60 is with the difference of test-purpose, and be arranged on the diverse location, example as shown in Figure 1a, its identification electrode 60 on the left sides, be to cooperate with the sensor that is used for detecting blood sugar, and shown in Fig. 1 b figure, its identification electrode 60 is to be used for the sensor of cholesterol detection to cooperate on the right, moreover, please refer to shown in Fig. 1 c, its identification electrode 60 is the sensor cooperations that are used for detecting Vetsin oxalic acid transferase (GOT) or bran amine pyruvic acid transferase (GPT) across both sides.

Thus, though can be arranged on the test piece diverse location by the identification electrode, and the different sensor of arranging in pairs or groups, reach above-mentioned purpose, but during fabrication, not only multi-form test piece need to change production line and make, and sensor also must be produced different identification equipments with the need, for manufacturing firm, not only do not meet economic benefit, and on cost, also can't reduce, and for the consumer, then may be little because of the test piece volume, and the identification electrode on it more accounts for very little zone, thus, even the identification electrode changes to some extent, but it is little because of changing, when detecting, whether sensor can't precisely identify this test piece is the test piece that cooperates, and causes erroneous judgement easily.
