1 is a view for explaining a pulse wave transmission rate measuring system 100 according to an embodiment of the present invention.

Referring to FIG. 1, a pulse wave transmission rate measuring system 100 according to an embodiment of the present invention includes a stage 110 for placing a wrist of a subject as shown in FIG. 2, a support 110 installed on one side of the stage 110, The support base 120 includes a support bar 121 vertically installed on the stage 110 and a guide bar 122 crossing the support bars 121.

The guide bar 122 is provided with a mounting portion 123. The mounting portion 123 is provided with a guide bar 122 vertically (Z direction) along a guide portion (e.g., a rail or the like) The stepping motor 125 for moving and the pulse sensor 11 and 12 are combined with the pulse sensors 11 and 12 and the pulse sensors 11 and 12 for measuring the radial artery as shown in FIG. (Direct current) motors 21 and 22 for moving them in the up and down direction (Z direction) (which can also be forward and backward X direction and left and right Y directions, respectively).

In addition, the pulse wave propagation velocity measurement system 100 according to an embodiment of the present invention includes an interface 40 connected to a control and monitoring device 50 such as a computer, a stepping motor 125 connected to the interface 40, And a measurement control unit 30 for measurement control by the motor driver 130 and the pulse sensors 11 and 12. [ The DC motors 21 and 22 are under the control of the interface 40.

The control and monitor device 50 is not limited to a computer such as a notebook PC and a desktop PC and may include various electronic devices such as a smart phone, an iPhone, and a PDA using a communication method using a mobile communication network or a wireless Internet .

Hereinafter, the operation of the pulse wave propagation velocity measurement system 100 according to an embodiment of the present invention will be described in detail with reference to the flowchart of FIG.

First, before measuring the radial artery of the subject's wrist, the distance (L) between two points (A-B) on the radial artery is measured in advance as shown in FIG.

After the distance between two points AB on the radial artery is measured, the subject's wrist is properly placed on the stage 110 (e.g., the forearm longitudinal direction is in the X direction) ) So that the pulse sensors 11 and 12 are lightly lowered at two points AB on the radial artery (S120).

For this purpose, a predetermined application (e.g., software) may be installed in the control and monitoring device 50 such as a computer, and a control command may be transmitted to the interface 40 through selection of a menu displayed on the display after execution of the application can do.

The interface 40 in the form of a DAQ board for data collection controls the movement of the DC motors 21 and 22 and controls the motor driver 130 and the measurement control unit 30 according to the control command of the control and monitoring device 50. [ So that the motor driver 130 controls the movement of the stepping motor 125 and the measurement control unit 30 controls the measurement and data collection of the pulse sensors 11 and 12.

That is, under the control of the interface 40, the motor driver 130 drives the stepping motor 125 to move the guide bar 122 up and down, or the DC motors 21 and 22 So that the pulse sensors 11 and 12 can be lightly lowered to the two points AB on the radial artery.

The measurement control unit 30 collects pulse waves to be measured by the pulse wave sensors 11 and 12 and transmits them to the control and monitor device 50 via the interface 40. The control and monitor device 50 displays the pulse waves, The waveform of the pulse wave can be displayed through the device.

The user manipulates the control and monitoring device 50 to monitor the pulse waves displayed on the display of the control and monitor device 50 so that good pulse waves can be appropriately used for pulse wave propagation velocity measurement, The pulse sensors 11 and 12 are moved in the X, Y and Z directions by the driving of the stepping motor 125 and the stepping motor 125 so that the pulse sensors 11 and 12 move the corresponding two points AB of the radial artery slowly A control command is generated to control the motor driver 130 and the stepping motor 125 or the DC motors 21 and 22 through the interface 40 so that the motor driver 130 and the stepping motor 125 or the DC motors 21 and 22 receive the corresponding control, A magnitude of a pulse wave signal having a good size or more can be observed (S130).

When the magnitude of a good pulse wave signal is observed so as to be suitable for the measurement of the pulse wave propagation velocity, the control and monitor device 50 inputs the measurement start command through a command input means such as a touch screen or a keyboard or a mouse on the display, A pulse wave can be received for a predetermined time (e.g., 5 seconds to 15 seconds including 10 seconds) and stored in a predetermined memory (S140). The control and monitoring device 50 may automatically generate a measurement start command when the magnitude of a good pulse wave signal exceeds a predetermined magnitude so as to be suitable for the measurement of the pulse wave transmission rate.

The pulse wave sensors 11 and 12 move toward the radial artery to observe the pulse wave according to the electronic control through the interface 40. The present invention is not limited to this, The pulse waves 11 and 12 may be moved to move the pulse detectors 11 and 12 toward the radial artery to observe the pulse waves. In addition, although not shown in the drawings, the pulse sensors 11 and 12 may not be fixed to the support base 120. At this time, the user may directly press the pulse sensors 11 and 12, It is also possible to move the pulse sensors 11 and 12 to the radial artery by moving one of the instruments equipped with the sensors 11 and 12 so that the pulse wave is observed and a measurement start command is generated.

The pulse detecting sensors 11 and 12 for measuring a pulse wave with respect to two points AB on the radial artery each include piezoresistive sensors (for example, six) and a temperature sensor, (For example, mV voltage magnitude output) according to the pressure applied by the radial artery, the control unit 40 controls the flow of the filtered and processed pulse wave for filtering the high frequency noise by using the analog circuit, To the device (50). At this time, the measurement control unit 30 appropriately increases or decreases the magnitude of the low-frequency component of the pulse wave outputted from the piezoresistive sensors in accordance with the temperature signal measured by each temperature sensor of the pulse sensors 11, 12 using an analog circuit can do.

In this way, the control and monitoring apparatus 50 can measure the pulse waves of the pulse sensors 11 and 12 collected through the measurement control unit 30 in the memory for a predetermined time (for example, 10 seconds) 4, the difference T between the pulse waves of the pulse detectors 11 and 12 is calculated (S150). Accordingly, the control and monitoring apparatus 50 calculates the pulse wave transmission rate by calculating the L / T using the distance L between two points (AB) on the radial artery measured and inputted in advance in S110 and displays it on the display (S160). The difference T between the pulse waves of the pulse detectors 11 and 12 may be a time difference between the start points of the pulse waves or a time difference between the maximum peak point and the minimum peak point or between the maximum and minimum peaks And so on.

In the pulse wave propagation velocity measuring system 100 according to the present invention, the two pulse sensors 11 and 12 are strongly intensified in the signal region and lightly dropped at two points on the radial artery until an accurate waveform is obtained. The pulse wave propagation velocity can be measured easily and simply by calculating and measuring the pulse wave propagation velocity using the pulse wave propagation distance and pulse wave propagation time between two points after storing the pulse wave data of the point. It is possible to improve the accuracy and reliability of the measured pulse wave propagation speed because it is less influenced by human errors or errors caused by the arterial bending degree.

Such a pulse wave propagation velocity measurement method can be used to determine diseases such as chronic heart failure, diabetes, hyperlipidemia, and arterial stiffness. Pulse wave velocity is usually physiologically delivered at 5 to 7 m / s. The pulse wave due to blood pressure consists of an advancing wave (or traveling wave) that develops and a reflected wave that returns to the heart from the distal end of the artery. The pulse wave velocity varies with age. In young people, the PWV is relatively low because the arteries are elastic, and the reflected pressure wave occurs in the diastole, increasing the perfusion (flow of blood through the tube) to the coronary arteries. The present invention can be used effectively to diagnose a subject's disease by measuring the propagation velocity of the progressive wave or the reflected wave.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the claims.
