Embodiment Construction

[0085] figure 2 It is a structural schematic diagram of a portable Raman spectrum blood glucose meter.

[0086] (1) The system uses an 830nm laser diode as the excitation source for Raman spectroscopy, and the light source is in the form of optical fiber output.

[0087] (2) The output end is output as a parallel beam through a collimating lens assembly. After the output, it needs to pass through a narrow-band laser filter to filter out other wavelengths of stray light when performing Raman spectroscopy, and only let the laser wavelength pass through. (3) Then there is an inverse telephoto form (one convex and one concave) to form a telescope system to adjust the beam size (the relative length between the lenses can be changed), and directly irradiate the sample through the small hole on the all-gold-coated flat mirror.

[0088] (4) Backward Raman scattered light first passes through a plane mirror for beam turning, then collects and converges with a Fresnel lens, and then pl...

Abstract

The invention discloses a portable Raman spectrum noninvasive glucose meter, belonging to the technical field of a noninvasive glucose medical measurement instrument of a non-destructive testing technology. On the premise of accordance with national regulation and on the basis of guarantying the characteristics of convenience for carrying, simpliness for use, measurement algorithm accuracy and the like of the portable glucose meter independently developed and researched, the Raman spectrum detection based portable glucose meter for detecting blood sugar is adopted and has the advantages of no destruction, difficulty in infection, no pollution, fast detection and the like.

Description

technical field [0001] Medical measuring instruments → non-invasive medical measuring instruments for non-destructive testing technology. Background technique [0002] According to the survey in 2010, there are currently 92 million people with diabetes and 148 million people with prediabetes in my country. Diabetes has become one of the main problems that seriously affect my country's public health. In the field of blood glucose monitoring, only 1.5% of diabetics in my country have their own blood glucose monitors, while more than 90% of diabetics in Europe and the United States have their own portable blood glucose monitors. At present, my country's blood glucose meter product market is mainly occupied by foreign brands such as Johnson & Johnson of the United States and Roche of Germany. Domestic brands only occupy less than 10% of the market share, and most domestic brands of blood glucose meters and corresponding test strip plug-ins have varying degrees. coordination iss...
