Background

The dynamic blood glucose monitor (CGMS) is one of diagnosis and treatment instruments of endocrinology, and is used for collecting blood glucose dynamic change data of diabetics for a plurality of days and making a monitoring tool of blood glucose maps. Through the instrument, doctors can comprehensively know the blood sugar fluctuation type and 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 subcutaneous implantable sensor, and the dynamic blood sugar detector has the characteristics of strong detection function, small volume, convenient use, small pain and the like, and can accurately grasp the blood sugar condition of patients with abnormal blood sugar and complicated illness. The glucose oxidase contained on the subcutaneous sensor reacts with the glucose in the subcutaneous tissue fluid, and the generated electric signal is transmitted by the sensor to analysis software through a transmitter and then converted into a blood glucose value.

Because the sensor needs to be implanted into a human body, the period of contacting the human body is long (about 20 days); this requires a longer service life for the sensor; some patients have rejection and pain to the sensor, which requires the sensor to have better biocompatibility and mechanical properties; in addition, the sensitivity of the sensor to react with substances in the human body, the repeatability precision of the sensor, corrosion resistance and other performances are also important. Therefore, it is necessary to detect the performance of the sensor.

Defining the number of motor rotations as a software limit in the control module system program can thus avoid transitional counterclockwise or clockwise rotation of the sensor placement plate 134, resulting in an inability to better secure the sensor.
