Embodiment Construction

[0043] The method for non-invasively measuring blood spectrum and components of the present invention will be described in detail below with reference to the embodiments and the accompanying drawings.

[0044] The method for non-invasively measuring blood spectrum and components of the present invention adopts such as figure 1 The shown method includes the following steps:

[0045] 1) Use a high-speed spectrometer to continuously measure the transmission spectrum of the measured object (where: t—time; λ—wavelength):

[0046] { A 1 1 , A 2 1 , A 3 1 , . . . . . . , A m 1 } , ...

Abstract

The invention discloses a method for the noninvasive measurement of blood spectra and components, which comprises the following steps: 1, adopting a high-speed optical spectrometer to continuously measure the transmitted spectra of a measured body: Alambda:{A1, A2, A3, ellipsis, Am}, {A1, A2, A3, ellipsis, Am}, ellipsis {A1, A2, A3, ellipsis, Am}; 2, sequencing light intensity values of all wavelengths according to the time for a plurality of continuous spectra to obtain a pulse wave of each wavelength: A1: {A1, A1, A1, ..., A1}, A2:{A2, A2, A2, ellipsis, A2}, ellipsis, A1:{Am, Am, Am, ellipsis, Am}; 3, performing Fourier transformation on the pulse wave of each wavelength, taking a harmonic wave aj with the maximum amplitude value, and rearranging the amplitude value of the harmonic wave of each wavelength according to a time sequence to form a spectrum {a1, a2, a3, ellipsis, am} which is an artery blood spectrum for an artery part, wherein i is the harmonic wave with the maximum amplitude value, and j is the wavelength; and 4, performing stoichiometric analysis on the artery blood spectrum so as to detect out the blood components in a noninvasive mode. The method does not need to collect blood directly, cannot cause any damages and infections to a human body, can achieve real-time monitoring, and cannot cause secondary pollution.

Description

technical field [0001] The invention relates to a method for measuring the spectrum of a substance. In particular, it relates to a method for non-invasively measuring blood spectrum and components without drawing blood. Background technique [0002] Usually, measuring the spectrum of blood naturally requires that the blood be drawn from the animal or human body before the measurement of the blood spectrum can be performed. But drawing blood is necessarily traumatic, with the risk of infection and other hazards. Therefore, the detection of blood spectrum has always been regarded as a dream. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for noninvasively measuring blood spectrum and components without drawing blood to realize blood spectrum measurement. [0004] The technical solution adopted in the present invention is: a method for non-invasively measuring blood spectrum and components, including th...
