example 1

[0016] Example 1, see figure 1

[0017] From the broadband light source 1, a continuous xenon lamp is used in this embodiment, of course, a white light diode can also be used to emit light beams ranging from visible red light to near-infrared light to irradiate human tissue 2, and the transmitted light passes through the spectroscopic device 3 after being focused. Adopt prism, certainly also can adopt grating or acousto-optic modulation device to form, the light through spectroscopic device 3 is received by photosensitive sensor 4, what photosensitive sensor 4 of the present invention adopted is photosensitive tube, and photosensitive sensor 4 converts the light signal that receives into electric The signal is transmitted to the data processing device 5. In the present embodiment, the microprocessor chip model 89C51 used by the data processing device 5 can certainly also adopt other types of chips with equivalent functions. The data processing device 5 uses independent compon...

[0018] Example two, see figure 2

[0019] From the broadband light source 1, a continuous xenon lamp is used in this embodiment. Of course, a white light diode can also be used to emit beams from visible red light to near-infrared light and then pass through the spectroscopic device 3. The spectroscopic device 3 of this embodiment adopts a prism. It can be composed of grating or acousto-optic modulation device. The light passing through the spectroscopic device 3 is irradiated to the human tissue 2, and the transmitted light is received by the photosensitive sensor 4. The photosensitive sensor 4 of the present invention uses a photosensitive tube, and the photosensitive sensor 4 converts the received optical signal into an electrical signal and transmits it to the data. The processing device 5, in this embodiment, the microprocessor chip model 89C51 used by the data processing device 5, of course, other types of chips with equivalent functions can also be used. The data pro...

Abstract

In the technological scheme of the present invention, the measuring method includes the following steps: irradiating the measured body with wideband light beam, leading the transmitted light with a light splitting device to a photosensitive sensor, and transmitting the signal of the photosensitive sensor to a computer for processing. The present invention has accurate measurement, can elimiante the effect of differences in individual, pulse amplitude, blood turgor, etc. to measurement, and can measure several blood components.

Description

technical field [0001] The invention relates to a blood component measuring method and instrument, in particular to a non-invasive arterial blood component measuring instrument and a measuring method thereof. Background technique [0002] The importance and great value of non-invasive detection of blood components, such as blood oxygen, blood sugar, blood lactic acid, 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. [0003] In 1977, the American scientist Jobsis first reported the experimental results of using near-infrared light to observe the changes in the content of oxyhemoglobin, reduced hemoglobin and cytochrome c in the brain of adult cats, revealing that near-infrared light (700-1300nm) has a lower concentration in biological tissues. decay rate and th...
