Description

[0001] The present invention relates to an arm model for training blood pressure and pulse measurement,

The present invention relates to an arm model for blood pressure and pulse measurement training, and more particularly, to an arm model for training the human body to have the same training effect as blood pressure measurement or pulse measurement To an arm model for blood pressure and pulse measurement training capable of controlling and monitoring through communication with a microprocessor and incorporating an evaluation function program so as to enable the practitioner's learning effect and objective evaluation

In general, pulsatile cardiology is a measure of the expansion of arterial blood vessels due to blood loss during cardiac contraction. It is usually measured in the carotid artery, brachial artery, femoral artery, and radial artery. The radial artery to be implemented in the present invention is an artery located in the wrist, most of which is performed in the radial artery, and is an index for recognizing systolic blood pressure when measuring blood pressure in the brachial artery.

In addition, blood pressure is the easiest and easiest way to clinically measure health today, and refers to the pressure on the blood vessel wall when blood is flowing through the blood vessel. Blood pressure can be measured at various sites, but generally measures arterial blood pressure at the forearm of the heart.

When displaying blood pressure, it is expressed as 'systolic blood pressure' and 'diastolic blood pressure'. Systolic blood pressure refers to the body's systolic blood pressure when the heart contracts and exhales the blood. Diastolic blood pressure refers to the lowest blood pressure in the human body when the heart relaxes and receives blood.

The method of measuring blood pressure is divided into direct method and indirect method. The direct method is a method of measuring blood pressure by inserting a catheter into an artery and then connecting it to a blood pressure monitor. Indirect method is palpation which can measure systolic blood pressure by using air bag called cuff and auscultation which measures systolic blood pressure and diastolic blood pressure through coronary artery stenosis .

In the acceleration method, sphygmomanometry is the part where the pulse disappears by finding the part where the pulse disappears while inflating the pressure in the cuff to a high position while measuring the pulse after measuring the pulse on the upper arm.

The stethoscopic method first inflates the cuff to the upper arm and then inflates the pressure in the cuff to a position higher than the predicted systolic pressure. When the cuff pressure is higher than the systolic pressure, the blood vessel is occluded. When the pressure in the pressure band is gradually reduced, the pressure of the cuff becomes lower than the systolic pressure, and the blood flows and Korotkoff sounds begin to be heard. Korotkoff sounds can be heard by placing a stethoscope in the brachial artery beneath the cuff. When the pressure of the cuff gradually decreases from the systolic pressure, the Korotkoff sound gradually decreases and disappears at any moment. The diastolic pressure is the pressure at which the Korotkoff sound disappears.

In the inside of the model unit 110, a pulse sound unit 120, a control unit 130, and the like described later may be accommodated.

The pulsating sound unit 120 includes a speaker 121 which is built in between the wrist 110a and the upper arm 110b and the forearth 110c of the mock-up unit 110 and outputs korotkoff sounds, And a pulse module 122 that implements a pulse.

The speaker 121 is installed between the wrist 110a and the upper arm 110b and the forearm 110c of the mock-up unit 110 and outputs korotkoff sounds stored in the controller 130. [ At this time, the controller 130 may include a sound controller 134 for converting a pulse waveform into a sound source in a file format such as MP3 and transmitting the sound source to the speaker 121.

The artificial blood vessel 123 may have a shape similar to an actual blood vessel. For example, the artificial blood vessel 123 may have a cylindrical shape, and may be formed of an elastic material such as rubber, silicone or the like as well as a synthetic resin. The artificial blood vessel 123 may be attached to a resonance plate 121a of the speaker 121 so that pulsation may be generated by vibrations generated when korotkoff sounds are output from the speaker 121. [

The protection panel 124 is formed on the upper surface of the speaker 121 to form a slot 125 in which the artificial blood vessel 123 is received in the form of a flat plate and to protect the speaker 121 and the artificial blood vessel 123, And a membrane sensor 131 is mounted on the upper surface thereof.

The membrane sensor 131 can detect the presence or absence of palpation in a relatively wide area and can be easily placed on the upper part of the pulse acoustic unit 120 because the thickness thereof is thin. The membrane sensor 131 is mounted on the upper surface of the protective panel 124 when the pulse acoustic unit 120 includes the artificial blood vessel 123 and the protection panel 124. [ The membrane sensor 131 senses the presence or absence of palpation between the upper arm 110b and the forearm 110c.

The control unit 130 may include an optical sensor 132 and a cuff 10 mounted on the upper arm 110b of the model unit 110 to detect whether the cuff 10 is wrapped or not, And a pressure sensor 133 mounted to measure the pressure of the fluid.

The optical sensor 132 senses whether the cuff 10 of the blood pressure monitor is installed at an appropriate position. On the other hand, the pressure sensor 133 senses the pressure of the cuff 10.

The monitoring unit 140 outputs sensing information of the sensors 131, 132, and 133 through the screen through wireless communication with the control unit 130. Specifically, the monitoring unit 140 determines whether the cuff 10 is installed at an appropriate position And the pressure of the cuff 10 can be displayed in real time.

According to an embodiment of the present invention, the control unit 130 and the monitoring unit 140 are equipped with Bluetooth modules 135 and 145 for receiving and transmitting the frequency of the Bluetooth communication band so that wireless communication is performed.

FIG. 5 is a flowchart of training for measuring blood pressure and pulse using an evaluation program built in the monitoring unit.

First, when the optical sensor 132 detects the installation of the cuff 10, the pressure sensor 133 measures the pressure of the cuff 10. At this time, the microprocessor 136 of the control unit 130 compares the measured pressure P with the diastolic pressure DIA and measures the measured pressure P when the measured pressure P is higher than the diastolic pressure DIA. And the systolic pressure (SYS). If the measured pressure P is greater than the systolic pressure SYS as a result of the comparison, a stop signal is output to the pulse acoustic unit 120 to stop the pulse. If the measured pressure P is smaller than the systolic pressure SYS, And outputs a driving signal to the pulse acoustic unit 120 to output a Cortocarp sound.
