The pressure indicated in each of FIGS. 5 and 6 may represent a static pressure.

In FIG. 5 , a horizontal axis may represent time and a vertical axis may represent intensity of a pulse pattern, and each graph may represent a pulse pattern according to static pressure.

And, in FIG. 6, the horizontal axis may represent a static pressure, and the vertical axis may represent a signal (Output signal) according to the pulse wave amplitude of a pulse pattern by dynamic pressure measurement.

As shown in Figure 4, the three-dimensional pulse pattern measuring system of the present invention, the three-dimensional pulse pattern measuring device 100 of the present invention formed of the above configuration; an analysis device 200 that receives a signal from the 3D pulse pattern measuring device 100 and analyzes elasticity and pulse of the user's blood vessel 10; and a display device 300 that receives information from the analysis device 200 and displays it on a screen.

Each of the pressure sensor 111 and the distance sensor may transmit signals to the analysis device 200 in a wired or wireless manner, and the analysis device 200 may analyze the characteristics of the blood vessel 10 by analyzing these signals. there is.

The analysis device 200 may derive the degree of elasticity of the blood vessel 10 by using a ratio between the static pressure applied by the sensing unit 110 to the blood vessel 10 and the moving distance of the moving unit 122 . Specifically, when the sensing unit 110 presses and compresses the skin 20 on the blood vessel 10, in the pressure sensor 111, the sensing unit 110 pressurizes the skin 20 and the blood vessel 10. , and the distance sensor may measure the moving distance of the moving unit 122 .

And, as shown in FIGS. 5 and 6, as the sensing unit 110 moves forward, the signal strength of the pulse pattern (Output signal ) increases, and after the critical static pressure (the static pressure at which the rate of increase begins to decrease rapidly, corresponding to 4.14 kPa in FIGS. 5 and 6), the signal intensity of the pulse pattern decreases and the intensity of the pulse pattern changes It can be seen that the width decreases.

That is, when the static pressure applied by the sensing unit 110 to the blood vessel 10 reaches the critical static pressure, a pulse pattern of the maximum signal intensity is formed. In this case, the internal pressure and the static pressure of the blood vessel 10 can match this.

At this time, the moving distance of the moving unit 122 may represent the deformation (strain) of the blood vessel 10, and the critical static pressure may represent the pressure within the blood vessel 10. Accordingly, in the analysis device 200, the critical static pressure By dividing the pressure by the moving distance of the moving unit 122, the degree of elasticity (kPa/mm) of the blood vessel 10 can be derived.

In the 3D pulse pattern measuring system of the present invention as described above, a plurality of 3D pulse pattern measuring devices 100 are formed, and a measuring position of one 3D pulse pattern measuring device 100 and another 3D pulse pattern are measured. Measurement locations of the device 100 may be different.

As described above, in the case of using two 3D pulse pattern measuring devices 100, one 3D pulse pattern measuring device 100 is applied to a portion of one blood vessel 10 for one blood vessel 10. It is possible to perform measurement using a different 3D pulse pattern measurement device 100 in another part of one blood vessel 10 .

In this way, when measuring different points in one blood vessel 10 using a plurality of 3D pulse pattern measuring devices 100, one 3D pulse pattern measuring device 100 and another 3D pulse rate A distance between the pattern measuring devices 100 and a phase difference between signals of each of the three-dimensional pulse pattern measuring devices 100 may be measured.

The propagation speed of the pulse wave can be measured using the distance and phase difference between one 3D pulse pattern measuring device 100 and the other 3D pulse pattern measuring device 100 as described above, and the propagation speed of the pulse wave can be used. Thus, the degree of elasticity of the blood vessel 10 may be measured.

Specifically, when the elasticity of the blood vessel 10 decreases and the stiffness of the blood vessel 10 increases, the pulse wave propagation speed in the blood vessel 10 increases, and when the pulse wave propagation speed increases, the reflected wave Due to the increase in speed, it appears overlapping with the traveling wave, and the blood pressure rises during the contraction of the heart, which affects the cardiovascular (10), cerebrovascular (10), coronary arteries, and peripheral blood vessels (10), resulting in health problems of the blood vessels (10). may occur.

Therefore, the propagation speed of the pulse wave measured as described above is compared with the propagation speed of the pulse wave in the normal blood vessel 10, and the rate of increase in the propagation speed of the pulse wave is calculated to compare the elasticity of the normal blood vessel 10 with the current blood vessel 10. ) can be derived.

In addition, by deriving the elasticity of the current blood vessel 10 as described above, the age of the current blood vessel 10 can be estimated by comparing the elasticity of the normal blood vessel 10 with the elasticity of the current blood vessel 10 .

The analysis device 200 may derive a pulse pattern by measuring the dynamic pressure measured by the sensor 110 for each hour. As shown in FIG. 5 , by measuring the dynamic pressure using the pressure sensor 111 , the pulse wave oscillation of the blood vessel 10 can be measured in real time, and the pulse wave oscillation over time can be displayed as a graph.

Depending on the static pressure of the pressure sensor 111 measured by the sensor 110 pressing the skin 20 on the blood vessel 10, the vibration of the pulse wave measured by the pressure sensor 111 may change in intensity and shape. . That is, the measured value of the dynamic pressure may vary according to the change in the static pressure of the sensing unit 110 . Accordingly, a pulse pattern for each static pressure can be derived, and a pulse pattern at the critical static pressure as described above can also be derived.

7 is a schematic diagram of a 3D graph according to an embodiment of the present invention.

The display device 300 may display a three-dimensional graph having an x-axis indicating a static pressure or a moving distance of the moving unit 122, a y-axis indicating time, and a z-axis indicating a pulse pattern.

First, the x-axis, y-axis, and z-axis may be displayed on the screen of the display device 300 . And, as described above, by measuring the static pressure using the pressure sensor 111 and measuring the moving distance of the moving unit 122 using the distance sensor, the static pressure or the moving distance of the moving unit 122 is x can be displayed on the axis.

In addition, time can be displayed on the y-axis, and the intensity of the pulse pattern can be displayed on the z-axis. Accordingly, the graph of the pulse pattern is formed over the xz plane and the yz plane, so that each value A three-dimensional graph can be formed for

By using the 3D pulse pattern measuring device 100 and the 3D pulse pattern measuring system as described above, it is possible to simply measure the elasticity and pulse pattern of the blood vessel 10 in a non-invasive way, and by using this, the blood vessel 10 ), and the presence or absence of abnormalities in the pulse pattern can be conveniently checked.

First, in the first step, the sensing unit 110 may contact the skin 20 where the user's blood vessels 10 are located. And, in the second step, the driving unit 121 moves the moving unit 122 so that the sensing unit 110 moves, so that the sensing unit 110 can press the user's skin 20 .
