blood pressure test device

Abstract

The present invention relates to a blood pressure testing device and a blood pressure testing method using the same. By using a pressurizing part to pressurize a test site, the highest pressurization value that can produce the highest pulse pressure and the highest pulse pressure are calculated, and the sensed The blood pressure value is corrected by the elastic coefficient of the skin and blood vessels at the test site, the pulse pressure attenuation rate, and the hardness of the blood vessels and skin, and the actual blood pressure value is calculated, which can accurately test the blood pressure of the test object and can The cycle continuously and accurately measures the blood pressure of the test subject for a certain period of time. More accurate monitoring can be achieved by monitoring blood pressure in normal individuals or by confirming circadian blood pressure rhythms with continuous blood pressure measurements at 1-minute intervals, or by taking small changes or averages at 10-second intervals of blood pressure that may vary based on respiration or other factors. Monitor blood pressure steadily.

Description

technical field [0001] The present invention relates to a blood pressure testing device and a blood pressure testing method using the same, more specifically, to a blood pressure test by pressurizing a blood vessel and testing the reaction pressure, and correcting the elastic coefficient of the skin and the blood vessel, Therefore, the blood pressure testing device which can measure accurate blood pressure and realize continuous blood pressure tracking and the continuous blood pressure testing method using it. Background technique [0002] Generally, blood pressure testing devices include devices using invasive methods and devices using non-invasive methods. [0003] As the invasive method, a representative example is a method of inserting a catheter for measuring blood vessel pressure into a peripheral artery and directly measuring the blood vessel pressure, which has a risk of arterial bleeding, as a device for testing health status due to the need for invasiveness into th...

Problems solved by technology

[0013] For this device, since it has electrocardiogram (ECG) and photoplethysmography (photoplethysmography, PPG) instruments, blood pressure can be tested, but it is cumbersome because two devices are required and blood pressure tests need to be performed on various parts of the body , users may find it inconvenient

Moreover, the accuracy of the measured blood pressure is more dependent on the shortcomings of the two devices used in the method than the precision of the blood pressure itself
