Abstract: The present disclosure relates to a two-stage blood glucose prediction method based on pre-training and data decomposition. The method includes the following steps: combining blood glucose data of healthy people and diabetic people to develop a pre-training model; collecting data of diabetic patients to be predicted; performing missing value imputation processing and smooth processing on the data of the diabetic patients; performing mode decomposition on the data; performing sample entropy analysis; importing the processed data of the diabetic patients into an ensemble learning module. In accordance with the present disclosure, the blood glucose data of healthy people and diabetic people are combined at first to train a blood glucose prediction model as a pre-training model, and the model is enabled to have a prediction data reserve, so as to solve the problem that a blood glucose concentration of a patient outside samples cannot be predicted well.

Abstract: The present invention discloses an auxiliary implantation device for a biosensor. The auxiliary implantation device for the biosensor includes an emitting tube assembly, a battery assembly, and an emitter assembly. The emitting tube assembly is configured to drive a slider to emit a sensor to a human body through an elastic force and pull back the slider through the elastic force to enable the slider to be rapidly separated from the sensor.
