Double-spectrum noninvasive blood glucose detection device

Abstract

The invention discloses a double-spectrum noninvasive blood glucose detection device, belongs to the field of optical engineering and novel medical detection instruments, and particularly relates to human body noninvasive blood glucose detection. The double-spectrum noninvasive blood glucose detection device is composed of a radiation light source, an optical integrating sphere, a measurement hole, bandpass filters, photoelectric sensors, a signal processing circuit and the like. By adoption of the double-spectrum noninvasive blood glucose detection device, a noninvasive glucometer which can operate within the spectrum range from the near-infrared spectrum (about 1 [mu]m) to the terahertz spectrum (about 100 [mu]m) can be established. According to the double-spectrum noninvasive blood glucose detection device, a light beam emitted by the light source is guided into the optical integrating sphere, the fingertip of a human body is fixed to a specific position in the optical integrating sphere and radiated by the light beam repeatedly, and then electric signals which can reflect spectrum information of the human body are collected through the two sets of bandpass filters with different wavelengths and the photoelectric sensors on the outer wall of the optical integrating sphere; and the electric signals are analyzed and calculated through the signal processing circuit, and blood glucose concentration information is obtained finally.

Description

technical field [0001] The invention belongs to the field of optical engineering and new medical detection instruments, and in particular relates to a human body non-invasive blood sugar detection device. Background technique [0002] Diabetes is one of the four major diseases that endanger human health, and it is a worldwide epidemic disease. Currently, about 10% of adults in the world suffer from this disease. In my country, according to the diabetes epidemiological survey results published by the Diabetes Society of the Chinese Medical Association in 2013, the prevalence of diabetes among people over 30 years old is 11.6%, and it is estimated that there are 139 million diabetic patients nationwide. At present, the basic method of diabetes treatment and control is to measure blood sugar frequently, and control blood sugar through diet, oral medicine or insulin injection based on blood sugar concentration. Most of the traditional blood sugar measurement methods use bioch...

Problems solved by technology

There are some problems in the above methods, including: most single-spectrum channel measurement methods are easily affected by human body and environmental factors, and its measurement accuracy is difficult to guarantee

However, the measurement method using the semi-transparent and semi-reflective dual-spectrum channel still has the asymmetrical factor of the optical path, and its measurement accuracy is also affected.
