Embodiment Construction
[0056] The minimally invasive, dynamic and continuous detection method of human blood glucose concentration of the present invention is realized on the micro-flow liquid comprehensive processing system disclosed in the patent application with the application number of 200810052117.9. First, the skin is pretreated with low-frequency ultrasound, and the lipid bilayer structure in the stratum corneum of the skin is destroyed by the cavitation of low-frequency ultrasound to increase the permeability of the skin, and then the tissue fluid is quickly extracted from the skin by vacuum negative pressure. , and detect the skin impedance / resistance during the tissue fluid extraction process, and then transport the extracted tissue fluid to the surface plasmon resonance measurement system through the microchannel, and use the surface plasmon resonance protein binding measurement technology to measure the glucose concentration in human tissue fluid, and finally use The volume of tissue flu...
