Non-invasive detector and detecting method for biochemical parameters of human blood

Abstract

The invention discloses a non-invasive detector and a detecting method for biochemical parameters of human blood. The non-invasive detector mainly comprises a clamp unit (10), a data acquisition unit (20) and a data processing unit (30). Before measurement, the clamp unit (10) is adjusted to achieve the optimal measuring pressure, and the temperature of a measured region is transferred by a temperature sensor arranged at the front end of a spectral acquisition probe of the data acquisition unit (20) to the data processing unit (30) as an input of a correcting model for prediction computation.By the measures, errors introduced by pressure and temperature in the measuring process can be eliminated, the measuring accuracy of the biochemical parameters of the human blood in the invention canbe improved, the computing complexity is reduced by introducing a major component number selecting method by the correcting model arranged in the data processing unit (30), ineffective information inthe spectra can be removed, and the measuring accuracy of the biochemical parameters of the human blood can be further improved.

Description

technical field [0001] The invention relates to medical testing equipment, in particular to a non-invasive testing instrument and testing method for human blood biochemical parameters. Background technique [0002] Blood biochemical parameters, such as blood sugar, triglycerides, total cholesterol, and total protein content, are important indicators that reflect the health of the human body. Existing equipment for detecting biochemical parameters of human blood usually needs to puncture the blood vessels of the subject to collect blood samples, and then perform laboratory analysis on the blood samples to obtain the values ​​of biochemical indicators. Because this detection method will cause pain and potential danger of infection to the subject, and it takes a certain period of time to obtain the detection result, the detection result cannot be obtained immediately, so the real-time performance is poor. Therefore, a non-invasive detection technology for human blood biochemic...

Problems solved by technology

However, in the process of non-invasive detection of blood biochemical parameters, the detection results are susceptible to interference from many external factors, such as measured pressure, measured temperature, and redundant information in the obtained spectrum, which leads to low measurement accuracy and reliability.
