Problems solved by technology

These methods generally have high requirements for instrument operation, expensive equipment, complex technology and high cost, and are not suitable for long-term use by the general population.
In recent years, the new non-invasive detection methods of vascular function mainly include: pulse wave waveform research, blood pressure index research, finger volume pulse wave method based on vascular reactivity test, finger temperature monitoring method, etc., most of which are currently in the research stage and have not yet formed a suitable method. An effective method for clinical testing and screening

Embodiment Construction

[0042] Including customized NIBP module with blood flow blocking function, finger temperature module (YSI400 temperature probe), blood oxygen module (BF type), USB to 4 serial port card, 5V3A stabilized power supply, and connection cable.

[0043] Example By analyzing the 12 temperature parameters and 7 routine parameters of 24 healthy people (G1) and 33 patients with cardiovascular disease (G2) who were age-matched (middle-aged), after a stepwise discriminant analysis, the two groups of people were screened out with Significant difference parameters, the following discriminant function (DTM discrimination) is obtained:

[0044] Y=-15.79-55.2*Slope2+0.278*Ti+0.059*PS

[0045] Among them: Slope2-The slope of the rising segment of the temperature signal after the end of the block; Ti-initial temperature; PS-systolic pressure

[0046] When judging the vascular function, you can substitute the Slope2, Ti and PS values ​​of a certain tester into the equation to calculate the value of Y. I...

Abstract

The invention relates to a vascular function noninvasive detecting method and device, and belongs to the field of medical measuring methods and devices. The device is characterized in that the device is combined by a plurality of physiological signal collecting modules which consist of a temperature module, a blood pressure cuff module and a blood oxygen module. The method comprises the following steps: according to the change of parameters of a finger end temperature signal, a blood oxygen signal and a pulse wave signal when the brachial artery is blocked and released, the collected data by clinical tests, and a signal processing and statistical analysis method, establishing a quantitative evaluation formula of the condition of the vascular function, and evaluating the condition of the vascular function. The method and device has the advantages of no invasion, simplicity in operation, and convenience in clinical application. The invention also provides a corresponding hardware structure and corresponding software for the vascular function noninvasive detection.

Description

Technical field [0001] The non-invasive detection method and device of blood vessel function belong to the field of medical measurement methods and devices, and are mainly used for non-invasive detection of blood vessel function status. Background technique [0002] According to statistics, about 15 million people worldwide die from acute cardiovascular and cerebrovascular events every year. The 2010 China Cardiovascular Disease Report pointed out that the morbidity and mortality of cardiovascular diseases (heart disease, stroke) in our country are on the rise. It is estimated that there are currently 230 million people with cardiovascular disease in China, every 5 adults One of them suffers from cardiovascular disease, and the number of people who die from cardiovascular and cerebrovascular-related diseases reaches 3 million every year, accounting for 41% of the total deaths. Therefore, it is important to realize early non-invasive detection of cardiovascular function in risk gr...
