Problems solved by technology

However, in actual clinical application, the analytical power of microcirculation blood flow measurement technology is still unable to effectively distinguish the blood flow changes brought about by the evolution of various clinical diseases. The more practical application is to apply to surface burns and scalds Similar applications for monitoring the status of skin growth recovery for patients with skin diseases, but for the "early detection and early treatment" of the aforementioned diseases, it will not be able to provide assistance

Embodiment

[0041] Several examples are enumerated below to describe the method of the present invention in more detail, but they are only for illustration and description, and are not intended to limit the present invention. The scope of protection of the present invention should be defined by the appended claims. .

[0042] A. Applied to early detection of diabetes

experiment example 1

[0043] Experimental example 1: The test location is Taixi Point

[0044] The instruments used in Experimental Example 1 include Laser Doppler Flowmetry (Laser Doppler Flowmetry, model: moor VMS-LDF), physiological signal amplifier, signal connector, analog-to-digital conversion card (ADC) and electronic sphygmomanometer.

[0045] The wavelength of the light source of the laser Doppler flowmeter is 400 to 700 nm, the measurable depth is 1 to 2 mm, the maximum light rate of the light source is 6 mW, the aperture of the fiber is 0.5 mm, the maximum sampling frequency of the instrument is 40 Hz, and each channel is allocated two An output connector that can output an analog signal from 0V to 5V. Measurable parameters include blood flow, diffuse light intensity, and temperature.

[0046] The physiological signal amplifier can capture the ECG signal after supplying the auxiliary circuit and power supply. In the test, the R wave is mainly captured for analysis. The electrocardiogr...

experiment example 2

[0061] Experimental example 2: The test location is Sanyinjiao point

[0062] The instruments and analysis methods used in Experimental Example 2 are the same as those in Experimental Example 1, so they will not be repeated here. The difference between Experimental Example 1 and Experimental Example 2 is to test the Sanyinjiao acupoint. The subjects were divided into the experimental group and the blank group, and no measurements were taken within three days after menstruation. Among the test subjects, those who were pregnant were excluded. The number of follicles of the subjects in the experimental group is greater than or equal to 10, or the total area of ​​follicles is greater than or equal to 140 square millimeters. The blank group were non-smokers with no obvious diseases and no history of gynecological diseases in the past, and did not take any drugs within three days before the test.

[0063] Similar to Experimental Example 1, the microcirculatory blood flow signal c...

Abstract

An apparatus for detecting surface microcirculation of an acupoint includes an acupoint locator, a bio-optical blood flow detection device and a signal analysis processor. The acupoint locator includes an optical probe disposed therein and is configured to let the optical probe substantially align with and be in contact with a surface of the acupoint of a human subject. The bio-optical blood flow detection device is configured to capture microcirculation signals of the surface of the acupoint of the human subject by the optical probe. The signal analysis processor is configured to receive and analyze the microcirculation signals.

Description

technical field [0001] The invention relates to a device for detecting microcirculation blood flow on the body surface of acupuncture points. Background technique [0002] Personal blood glucose detectors on the market are still mainly of the finger blood collection type. Such invasive blood glucose monitors cover almost all of the personal blood glucose monitor market. However, when using it, users will be troubled by acupuncture pain, difficult wound recovery, insufficient blood volume and need to repeat the test, etc. Diabetic patients are not willing to use it, which leads to insufficient number of effective tests, which impairs the clinical value of this monitoring. reference value. Therefore, the technology of analyzing and detecting diabetic patients in a non-invasive way has great application significance in the development of home biomedical electronics and telemedicine. In addition, if an effective early detection and less harmful measurement and evaluation meth...
