Problems solved by technology

[0004] However, the human body's evaporative heat dissipation accounts for a large proportion of the total human body heat dissipation, and the factor of human body's evaporative heat dissipation has not been considered in the previous metabolic rate thermal integration method, which greatly restricts the blood glucose measurement of the metabolic rate thermal integration method precision

Embodiment 1

[0032] Using a non-invasive blood glucose detector based on metabolic thermo-optical method to detect blood glucose in human body. In order to minimize the interference of factors such as ambient temperature, human body movement status and clothing on blood glucose detection, the measurement conditions need to be limited as follows during the detection process:

[0033] 1. The blood glucose test is carried out indoors, and artificial ventilation devices such as fans are turned off to keep the indoor environment in a state of natural convection;

[0034] 2. The indoor environment is controlled at 20°C to 26°C, try to keep it in a relatively constant state to ensure that the human body is in a thermal neutral zone;

[0035] 3. Before the measurement, each subject to be tested is in a resting state in the indoor environment, dresses to match the ambient temperature, and avoids sweating as much as possible to ensure that the human body is in a state of thermal equilibrium during t...

Abstract

The invention provides a non-invasive blood glucose detector based on a metabolic heat-optical method, and belongs to a human body blood glucose measurement device. The blood glucose detector comprises a detection probe and a data processing and displaying system, wherein the detection probe comprises a series of sensing measurement elements, such as an infrared radiation sensor, a thermistor, a humidity sensor, a light-wave receiver, a heat-conduction bar and the like, and is used for directly measuring parameters of detected positions of a human body; the data processing and displaying system comprises a microprocessor, as well as a display unit and a storage unit which are connected with the microprocessor respectively; a signal detected by the detection probe is processed by virtue of amplification filter, A / D (analog-to-digital) conversion and other modes, and then is input into the microprocessor; and the microprocessor carries out data processing according to a preset algorithm to acquire a blood glucose value detected by the detector, and displays and stores the blood glucose value. In the non-invasive blood glucose detector, a principle of combining a metabolic heat method and an optical method is adopted, so that the finally output blood glucose value has a higher reference value.

Description

technical field [0001] The invention relates to non-invasive blood sugar detection for human body, belongs to the field of human blood sugar measurement in medical equipment, and is specifically a thermo-optical integrated non-invasive blood sugar detector. Background technique [0002] Diabetes is an endocrine disorder. There is currently no cure for diabetes. The treatment of diabetes is based on frequent monitoring and control of blood sugar levels. The traditional method of invasively taking blood to measure blood sugar has obvious defects, which brings trauma and pain to the patient during the measurement process, and it is not convenient to realize continuous detection. Non-invasive blood glucose detection technology overcomes the shortcomings of traditional detection methods, and can effectively meet the needs of diabetics for real-time and frequent monitoring of blood glucose concentration. It is the development direction of blood glucose detection technology. Non-i...
