no. 2 Embodiment

[0064] On the basis of the above-mentioned embodiments, in this embodiment, the light source unit 100 is a quantum cascade laser that emits mid-infrared detection light of discrete wavelengths, including wavenumbers of 1155 cm -1 The detection light and wavenumber is 1500cm -1 of reference light. The calculation unit 400 obtains the blood glucose level of the subject to be measured by comparatively analyzing the absorbance of glucose to mid-infrared detection light of different wavelengths by using the differential absorption spectrum method. In this embodiment, the calculation unit 400 compares the wave number to 1155 cm -1 The differential absorbance was obtained to obtain the blood glucose value. A reference absorption spectrum is stored in the calculation unit 400, denoted as [A R (1155), A R (1500)], the reference absorption spectrum is respectively the mid-infrared absorption spectrum measured when the object to be tested has a reference concentration blood sugar val...

Abstract

The invention discloses mid-infrared noninvasive blood glucose detection equipment which comprises a light source part, a detection part, a receiving part and a calculating part.The light source part is used for sending mid-infrared detection rays to the detection part, the detection part has a detection face used for making contact with an object to be detected, the mid-infrared detection rays become emergent rays carrying information of the object to be detected, the receiving part is used for receiving the emergent rays and transmitting the emergent rays to the calculating part, and the calculating part is used for calculating a blood glucose value of the object to be detected according to the emergent rays.The blood glucose detection equipment can achieve the purpose of noninvasive blood glucose testing and adopts the mid-infrared detection rays for testing, the signal-to-noise ratio in the blood glucose detection process is effectively increased, and therefore more accurate blood glucose detection is achieved.

Description

technical field [0001] The present application relates to the technical field of blood sugar detection, and more specifically, to a mid-infrared non-invasive blood sugar detection device. Background technique [0002] Diabetes is the most common endocrine and metabolic disease in the world. According to the "Report on Nutrition and Chronic Disease Status of Chinese Residents (2015)", the prevalence of diabetes in adults over 18 years old is 9.7%. my country has become the undisputed number one diabetes country, and there is an increasing trend year by year. [0003] Among diabetics, the number of people using traditional invasive blood glucose meters has exceeded 50 million. The per capita annual consumption of blood glucose meter test strips is about 180, and the annual consumption of blood glucose meter test strips is about 9 billion. At present, due to the high pressure of social life, eating well and exercising less, often staying up late, excessive smoking and drinkin...
