Claim 12:
13. An insulin injection device, comprising: a wearable module, a detection module and a drug administration module, wherein:
the wearable module is respectively connected to the detection module and the drug administration module, and can be used for fixing the detection module and the drug administration module to a body of a user;
the detection module is used for detecting a blood glucose concentration of the user by a Raman spectrum, determining a dose of required insulin according to the blood glucose concentration, generating a corresponding drug administration instruction according to the dose of the required insulin, and sending the drug administration instruction to the drug administration module; and
the drug administration module is used for storing the insulin and injecting a corresponding dose of insulin into the body of the user according to the drug administration instruction;
the detection module comprises a light emitter, a light receiver and a processor;
the light emitter is used for emitting detection light to a subcutaneous tissue of the user through a skin of the user;
the light receiver is used for receiving scattered light formed by inelastic scattering of the detection light, and forming the corresponding Raman spectrum according to the scattered light; and
the processor is used for determining the blood glucose concentration of the user according to the Raman spectrum formed by the light receiver;
the processor is used for calculating the blood glucose concentration of the user according to the Raman spectrum through the following formula:

G=(1+e∫(Q1t)dt−ƒ(Q2t)dt/∫(Q2t)dt+∫(Q1t)dt)·(Q2t)dt 

wherein, G represents the blood glucose concentration of the user, Q1 represents an intensity of scattered light formed by the detection light in a skin layer of the user, Q2 represents an intensity of scattered light formed by the detection light in a subcutaneous tissue layer of the user, and t represents Raman shift of the Raman spectrum.
