Description

Method for detecting performance of sensor

Technical Field

The invention relates to the field of blood glucose monitoring, in particular to a method for detecting sensor performance.

Background

The dynamic blood sugar monitor (CGMS) is one of diagnosis and treatment instruments in the endocrinology department, and is used for collecting dynamic blood sugar change data of diabetics for multiple days and serving as a monitoring tool of a blood sugar map. Through the instrument, doctors can comprehensively know the blood sugar fluctuation type and the trend of patients, and the instrument has great significance for blood sugar control and diabetes treatment. The dynamic blood sugar detector consists of a glucose emitter and a blood sugar recorder, wherein the emitter is internally provided with a sensor which can be implanted under the skin, has the characteristics of strong detection function, small volume, convenient use, little pain and the like, and can accurately master the blood sugar condition of patients with abnormal blood sugar and complicated illness. Glucose oxidase contained in the sensor placed under the skin and glucose in subcutaneous interstitial fluid are subjected to chemical reaction, and the generated electric signal is transmitted to analysis software by the sensor through an emitter and then converted into a blood glucose value.

Because the sensor needs to be implanted into a human body, the contact period of the sensor with the human body is long (about 20 days); this requires a long service life of the sensor; part of patients have rejection reaction and pain to the sensor, so that the sensor is required to have better biocompatibility and mechanical property; in addition, the sensitivity of the sensor to the reaction of substances in the human body, the repeatability accuracy of the sensor, the corrosion resistance and other properties are also important. Therefore, it is necessary to detect the performance of the sensor. There is a need to establish a feasible detection method. And no detection standard is formed in the market at present.

At present, when the performance of a sensor is generally detected, a static detection mode is adopted, namely, in the detection process, relative motion does not exist between the sensor and a reagent, so that the accuracy of the detected data is low, and the error is large when repeated detection is carried out; moreover, the sensor parameters that can be detected are limited and the detection period is long. In the static detection mode, the detection environment of the sensor is greatly different from the environment in the human body, the accuracy is low, and the detection of the sensor in the human body cannot be truly simulated.

Further, in the step (6), the process of performing the reciprocating detection is consistent with the process of detecting the vibration, but the motion amplitude of the vibration detection is smaller than that of the reciprocating detection, and the frequency of the vibration detection is lower than that of the reciprocating detection.

Further, in the step (6), the specific process of performing the composite detection is as follows: on the basis of static detection, reciprocating detection and vortex detection are carried out simultaneously.

In some preferred modes, the sensor reciprocates up and down in the reagent, while the sensor reciprocates forward and backward in the reagent, during which the sensor performs detection.

In some preferred modes, in step (6), as shown in fig. 47, the specific process of performing vortex detection is as follows: on the basis of static detection, a third motor 206 in the reagent module 4 works (clockwise or anticlockwise) to drive a second gear 204 to work, the first gear 203 rotates along with the second gear, the reagent kit 201 connected with the first gear 203 rotates, reagents are uniformly mixed, and the sensor detects in the state.
