Description

Simulator for training of blood pressure and pulse measurement

The present invention relates to a simulator for training blood pressure and pulse measurement, and more particularly, to a simulator for training blood pressure and pulse measurement that allows a trainer to have the same training effect as measuring blood pressure and pulse on a human body.

In general, pulse examinations promote the expansion of arterial vessels due to blood ejection during cardiac contraction, and are mainly measured in carotid arteries, brachial arteries, femoral arteries, and radial arteries. The radial artery to be implemented in the present invention is an artery located inside the wrist, and most pulse examinations are performed in the radial artery, and the brachial artery recognizes systolic blood pressure when the blood pressure is measured at a position where the corotof is heard when the blood pressure is measured. It can be an indicator.

In addition, blood pressure is the easiest and simplest clinical measure of health today, which is the pressure on the walls of blood vessels as they flow through them. Although blood pressure can be measured in a variety of places, blood pressure in the arteries is usually measured at the forearm at the heart level.

The blood pressure is expressed as systolic and diastolic blood pressure. Systolic blood pressure refers to the highest blood pressure in the body as the pressure when the heart contracts and exhales blood. Diastolic blood pressure is the minimum blood pressure in the body when the heart relaxes and receives blood. In general, the blood pressure range of normal people is systolic blood pressure 120mmHg diastolic blood pressure 80mmHg

The method of measuring blood pressure is largely divided into direct and indirect methods. 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. The indirect method is a method of using an air bag called a cuff, which includes auscultation and an osillometric method.

 The stethoscope first places the cuff on the upper arm and then inflate the pressure in the cuff to a position above the predicted systolic pressure. If the cuff pressure is higher than the systolic pressure, the vessel is blocked. Afterwards, if the pressure in the pressure zone is gradually depressurized, the cuff pressure is lower than the systolic pressure, and the blood flows and Korotkoff sounds begin to be heard. Korotkoff sounds can be heard by placing the stethoscope in the brachial artery under the cuff. As the pressure in the cuff gradually decreases from the systolic pressure, the Korotkoff noise gradually decreases and disappears at some point. The pressure at which Korotkoff disappears is the diastolic pressure.

It is an object of the present invention to provide a blood pressure and pulse measurement training simulator capable of performing normal blood pressure and pulse measurement training so as to accurately measure blood pressure and pulse frequency of the subject during blood pressure and pulse measurement in clinical practice.

In addition, the radial artery and the brachial artery position is provided with a pulse module to provide a simulator for blood pressure and pulse measurement training that can palpate a pulse similar to the actual pulse rate.

It is also an object of the present invention to provide a blood pressure and pulse measurement training simulator for realizing a pulse rate similar to a real one by implementing a pulse rate through a horizontal movement of an elastic body during a pulse process of a pulse module.

In addition, the purpose of the present invention is to provide a simulator for blood pressure and pulse measurement training that can be trained to detect the position of the Korotkoff auscultation by sensing the blood pressure monitor so that it can be installed in the proper position of the arm, and palpate the pulse of the brachial artery. .

In addition, the systolic blood pressure, diastolic blood pressure, pulse rate per minute, auscultation gap, volume can be set through the input / output unit. And it aims to provide a simulator for blood pressure and pulse measurement training that can be pulse training.

In addition, it is an object of the present invention to provide a simulator for blood pressure and pulse measurement training to listen to the Korotkoff sound to a plurality of trainers using an external speaker.

In addition, educators can evaluate the trainer's blood pressure and pulse measurement practice, trainers can self-learn, and receive feedback on blood pressure and pulse measurement practice results to more effectively train blood pressure and pulse measurement practice training. The purpose is to provide a simulator for measurement training.

In addition, the purpose is to provide a simulator for blood pressure and pulse measurement training under the same conditions as the actual blood pressure measurement by outputting the Korotkoff sound source that distinguishes the systolic and diastolic pressure in stages.
