Embodiment Construction

[0010] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0011] refer to figure 1 The detection circuit of the non-invasive blood glucose detector includes a DSP chip, a reset module, a USB module, a liquid crystal display module, a combination key module, a serial port module, a FLASH module, an AD correction module, a hardware filter module and a sensor module. The signal is transmitted to the detection circuit board in parallel. The detection circuit first passes the two-way dual-wavelength light attenuation signal through the two-stage amplification and light intensity modulation circuit to realize the control of the light source intensity of the sensor and the display device, so that the measured value is within a reasonable range. The finger is properly placed to obtain finger pulse wave signals with appropriate bright...

Abstract

The invention provides a non-invasive blood sugar detection instrument, which comprises a detection circuit and a power supply circuit, wherein the detection circuit comprises a DSP (digital signal processing) chip, a reset module, a USB (universal serial bus) module, a liquid crystal display module, a combined press key module, a serial port module, a FLASH module, an AD (analog-digital) correcting module, a hardware filtering module and a sensor module. The non-invasive blood sugar detection instrument has the advantages that the structure of the detection circuit is simplified, the size of the detection instrument is effectively reduced, the power supply circuit ensures that the detection instrument can obtains stable power supply signals, further, the precision and the stability of the detection can be improved, and meanwhile, the power consumption is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of biomedical detection, and relates to a non-invasive blood sugar detector, and a method and device for non-invasive rapid detection of blood sugar. Background technique [0002] Diabetes mellitus is a common metabolic endocrine disease characterized by hyperglycemia, and is a worldwide epidemic. In recent years, with the development of my country's social economy, the improvement of residents' living standards, and the acceleration of population aging, the incidence of diabetes has been increasing year by year. At present, there are about 50 million diabetic patients in the country, and the annual growth rate is 0.1%. . Diabetes is harmful, mainly because of its serious complications, such as cardiovascular disease, kidney disease, eye disease, neuropathy and diabetic foot. There is currently no effective cure for diabetes, and blood sugar control is the only treatment. Timely blood glucose detection is ...
