Abstract

The invention relates to multiband reflection spectrum noninvasive blood component measuring device and method. The device is provided with a scanning device for a tongue body by utilizing a light source and a spectrum receiving device for receiving a scanning signal of the scanning device, wherein the light source is a supercontinuum light source or wave band; the scanning device carries out scanning by adopting optical fibers, and the like; and the spectrum receiving device adopts a spectrograph or a hyperspectral imager. The method comprises the following steps of: scanning the reflection spectrum distribution of the whole tongue body surface by utilizing the light source through the optical fibers; obtaining a reflection spectrum generated by the tongue body by the spectrum receiving device; calculating a multiband normalized reflection spectrum of blood; establishing a mathematical model by utilizing methods of main component analysis, artificial neural network, partial least-square regression, support vector machine signal analysis and statistics to obtain normalized spectrum data; and calculating by applying the established mathematical model to obtain the blood component content. The invention resists interference, can obtain more spectrum information and the image information of a measured part, increases information amount and improves the analysis precision of the blood component content.

Description

technical field

[0001] The present invention relates to a blood component measuring device. In particular, it relates to a multi-band reflection spectrum non-invasive blood component measuring device and method which can improve the analysis accuracy of blood component content. Background technique

[0002] The importance and great value of non-invasive detection of blood components (such as red blood cells, hemoglobin, hematocrit, etc.) for the diagnosis and treatment of diseases is beyond doubt. Not only that, the realization of non-invasive detection of blood components also has great academic significance and value in signal sensing, detection and processing. However, the existing detection methods need to draw blood samples and use biochemical analysis methods for detection, which is not only cumbersome to operate, but also brings pain to patients, and also has the risk of contracting other diseases, which limits the frequency and scope of blood component detection.
