Description

A kind of galvanochemistry type glucose sensor

The utility model relates to a kind of galvanochemistry type glucose sensor, belongs to the electrochemical sensor technical field, and it is applicable to the various clinical monitorings relevant with the blood sugar metabolism.

The mensuration of blood sugar is a basic test content in diabetes, hypoglycemia and the meningitic Clinics and Practices process.Particularly in recent years, along with diabetic's rapid increase, press for that a kind of highly sensitive, selectivity is strong, stable performance, easy to use, cost is low and be used in body or the glucose sensor of monitoring in real time.The glucose sensor of galvanochemistry type is to be expected to realize a class sensor that numerous advantages are rolled into one most, therefore development and the exploitation to it is 10 fens active research fields, its technology contents then mainly concentrates on the configuration design of curing, electrode of enzyme and mensuration scheme etc., and wherein the immobilization way of glucose oxidase is one of key factor of influence and the serviceability that is limiting glucose sensor.

The purpose of this utility model is a kind of galvanochemistry type glucose sensor of design, utilizes the immobilization way of new glucose oxidase, is mounted to a kind of pillar ampere-type glucose sensor, and this sensor bulk is little, easy to use and can repeatedly use.

A kind of galvanochemistry type glucose sensor of the utility model design, this sensor is a hollow cylinder, cylindrical outer wall has aperture, be provided with electrode in the aperture, be equipped with immobilized glucose oxidase paste in the cylindrical cavity, a cylindrical end has the electrode in lead and the right cylinder to link.

Use the glucose sensor of the utility model design, can monitor blood sugar, this electrode is safe in utilization, and is nontoxic, is applicable in body measurement, and required test liquid measure can arrive less and refer to blood, stable performance, and can repeatedly use.
