The present disclosure describes an
analysis method and
system for blood glucose fluctuation caused by
insulin leakage adsorbed by an NC membrane, the method comprising collecting a leakage image, adsorbing leakage at a target position by a
nitrocellulose membrane after a patient injects
insulin, and taking a picture of the
nitrocellulose membrane after adsorption of the leakage and a reference object to obtain a leakage image; analyzing the leakage image to determine a leakage area in the leakage image; determining a leakage area based on a resolution of the leakage image, the leakage area, and a reference object pattern; determining a leakage volume corresponding to the leakage area based on an adsorption capacity of the
nitrocellulose membrane and the leakage area; and determining an
impact of the leakage volume on blood glucose fluctuation of the patient based on an injection
dose, the leakage volume, a first blood glucose level and a second blood glucose level of the patient, the first blood glucose level and the second blood glucose level being blood glucose indicators before and after the patient injects
insulin, respectively. Thus, the leakage volume can be effectively, conveniently and non-invasively obtained to analyze the
impact of the leakage volume on blood glucose fluctuation.
