Description

Body fluid analyte detection device Technical Field The invention relates to the field of medical instruments, in particular to a body fluid analyte detection device. Background The pancreas in the body of a normal person can automatically monitor the glucose content in the blood of the person and automatically secrete the required insulin/glucagon. However, the pancreas of the diabetic patient has abnormal functions and cannot normally secrete insulin required by the human body. Diabetes is a metabolic disease caused by abnormal pancreatic function of a human body, and diabetes is a life-long disease.
