Problems solved by technology

The disadvantages of these two methods are that the body fluid collection time is more than 20 minutes, and the changes in blood sugar concentration cannot be reflected in real time; the second is that there is some damage to the skin
Due to the existence of individual differences, the non-invasive blood glucose monitoring by impedance spectroscopy has a large deviation, and the signal-to-noise ratio and sensitivity are difficult to improve

Embodiment Construction

[0029] The present invention is described in detail below in conjunction with embodiment.

[0030] Such as figure 1 As shown, the non-invasive detection device of pulse impedance spectrum blood sugar or other blood components of the present invention consists of a main control unit 2 and a frequency-sweeping constant current source 5 connected to the main control unit 2, a measurement unit 7, a display alarm unit 1, and a storage unit 3 and communication interface 4 form. The sweeping constant current source 5 is provided with a pair of excitation electrodes 8, and the excitation electrodes 8 are ring electrodes or electrocardiographic monitoring electrodes. The sweeping constant current source 5 is used to generate a weak alternating current with variable frequency and constant amplitude, which is fed into the human body through the excitation electrode 8 . The measuring unit 7 is provided with a pair of measuring electrodes 9, and the measuring electrodes 9 are ring electr...

Abstract

A non-invasive tester for detecting the pulse impedance spectrum, blood sugar and other blood components is composed of master control unit, sweep-frequency constant current source, measuring unit, display and alarm unit, memory unit and communiation interface. Its detection method includes such setps as measuring dynamic pulse wave resistance spectrum to obtain the pulse resistance spectrum, and calculating blood sugar and other blood components.

Description

technical field [0001] The invention relates to a detection device and a detection method for non-invasive detection of blood sugar or other blood components, in particular, to a device for realizing non-invasive measurement of blood sugar or other blood components by measuring body surface electrical impedance and its change with pulse wave Detection device and detection method thereof. Background technique [0002] Diabetes mellitus is a chronic metabolic disease caused by genetics, insufficient insulin secretion or low insulin function. The disease initially manifests as an increase in blood sugar concentration, which in turn endangers other organs and systems of the human body, leading to serious complications such as kidney failure, blindness, heart disease, neuralgia in the extremities, gangrene and even resection. Diabetes has become a serious threat to human health killer. In 2000, there were 180 million diabetic patients in the world, and 3.2 million people died o...
