Refer to, or with being needled into subcutaneously, however the tissue at these positions contains a large amount of blood vessels, and these methods are not all mentioned and how to be avoided
The interference of blood signal, even without recognizing dividing tissue liquid and blood.
Current method all ignores the feasibility and necessity of interstitial fluid glucose signal in detection corium.Blood in corium
It manages and is mainly enriched in the intersection of upper surface and epidermis and the intersection of lower surface and subcutaneous tissue, by protein inside skin corium
Fiber forms space structure, wherein being filled with tissue fluid, if it is possible to only collect the signal inside skin corium, so that it may have
Effect reduces the signal for carrying out autoblood, and safe and convenient.
