Perlong medical equipment company before study, small make up to introduce the two kind of use of automatic hematology analyzer to test the technology blood sugar analyzer development next, for everyone to continue this two other current use common blood glucose testing technology
3.Non-invasive blood glucose testing technology
Noninvasive blood sugar test is a kind of need not collected blood samples of blood glucose concentration measurement new technology, it will not damage the body any trauma, won't cause humoral infectious disease, use convenient in recent years, the research of this aspect has become the hot spot of the international academic, appeared far infrared spectra of near infrared spectral polarized light technology percutaneous reverse spin ion pump technology impedance measurements of principles measurement system
The company produces the Cygnus California GlucoWatch Biographer wrist watch type blood glucose detection device, to use negative ion pump technology, through the in vitro diagnostic reagent to the analysis of the body fluids, every 10 min read a data, and can continuous record 13 h, namely 78 a blood sugar leels, the second generation of the wrist watch type blood sugar test device GlucoWatch G2 Biographer (GWG2B) for the United States in 2002 approved by FDA for adults with a prescription and 7 ~ seventeen sales, Europe also approved to enter the market.
In recent years, domestic ShenTao ShenYaoChun also useful noninvasive blood sugar concentration to test research, and had made new progress of near infrared spectral technology in the analysis of material test has the following advantages: the area near infrared absorption coefficient is small; Apply to diffuse technology; Near infrared can in glass and quartz in penetrable; Investment and operation cost is low; Can be used for sample of qualitative, also can get high precision of quantitative results; Don't reagent, the polluting the environment; Determination very fast in a very short period of time has become a non-invasive blood glucose testing technology, the main research method.
But li gang, etc have argued that the biological internal organization structure and its composition is complicated, the near infrared spectrum absorption area is not significant, the spectral measurements of interference factors exist, leading to the signal-to-noise ratio and measuring precision is low, especially individual difference and detection conditions light body the accuracy of measurement have great influence, floating standards law detection technology can effectively reduce the measurement environment change and background of the samples change, human physiological background is to solve the problem of the most promising changes interfere with one of the scheme
The newly tang fei and introduces a kind of metabolic heat the whole legal noninvasive blood glucose detection technology, using temperature sensor infrared sensor humidity sensor and optical measurement device, as measured by the human body metabolism heat generation of blood flow velocity oxygen saturation, using the human body metabolic heat generation of blood glucose concentration of oxygen is for function, can work out what the blood sugar concentration
They for metabolic heat the whole legal non-invasive blood glucose detection technology research and developed prototype medical clinic patients in the crowd and clinical trials on the patient clinical trials, and to obtain the data analysis, the blood glucose testing results and the large biochemical analyzer to obtain the result of relative coefficients reach 0.856 experiments, metabolic heat the whole legal noninvasive blood glucose testing technique is feasible although no and automatic blood analyzer research and development of the analyzer move very quickly, but this kind of percutaneous detection equipment, by many factors, to improve the accuracy of the results.
