Background
Monitoring of blood glucose is very important for diabetics, and blood glucose values help to assess conditions of glucose metabolism disorders in diabetics. Currently, the detection of blood glucose can be divided into in vitro detection after blood collection and real-time detection of an implantable blood glucose sensor. When blood sugar is controlled by the method of in vitro detection after blood collection, blood collection is required to be carried out for a plurality of times every day, which brings heavy burden to the mind and the flesh of a patient, and on the other hand, because the number of times of measurement is limited, only blood sugar values at the time of measurement can be provided, and the fluctuation condition of the blood sugar values in one day cannot be completely reflected. Meanwhile, since the trend and direction of blood glucose change in the measured value are unclear due to the limitation of the number of measurements, the amount of insulin to be used is adjusted according to the measured blood glucose level, which may increase the possibility of hypoglycemia. The dynamic blood sugar detection can effectively solve the problems, and the practical dynamic blood sugar monitoring system not only can give the blood sugar value in real time, but also can display the change trend of the blood sugar, and can more accurately judge the change and the trend of the blood sugar by combining with the daily life work and rest of a patient, so that the method for detecting the blood sugar by using the implanted blood sugar sensor in real time is more and more popular.
At present can be used for clinical blood sugar continuous monitoring product, the microsensor of implanting in only subcutaneous tissue that obtains certain degree verification technically, for this reason, the field needs implant tiny, soft biosensor flexible detection part subcutaneously, and the puncture pipe penetrates subcutaneous with very fast speed, lets the painful sense drop to extremely low to leave sensor electrode part subcutaneously, realize continuous monitoring, and sensor portion on the skin needs to be fixed with skin.
