Description

[0001] The present invention relates to a chest model device and a cardiopulmonary resuscitation simulator comprising the same,

The present invention relates to a cardiopulmonary resuscitation simulator, and more particularly, to a cardiopulmonary resuscitation simulator capable of exercising chest compression under conditions similar to a human body.

Cardiopulmonary resuscitation is a procedure that restores cardiopulmonary function and resuscitates when cardiopulmonary function is seriously degraded or stopped. For normal breathing dysfunction or respiratory arrest, first perform artificial respiration after airway is secured, and then perform heart massage to restore heart function.

Artificial respiration refers to the artificial respiration is normally maintained by revitalizing the function of the lungs when the heart is running due to falling into water, poisoning or bleeding, but the breath stops and is in the housekeeping state. The artificial respiration method as the first life-saving treatment includes a breathing method of blowing the exhalation of the practitioner into the lungs of the patient and a water artificial respiration method in which the practitioner presses the chest of the patient by using the hand to inhale and exhale.

In addition, cardiopulmonary resuscitation is used as a method to revitalize cardiac function when the heart stops beating due to falling, electric shock, or poisoning. Cardiopulmonary resuscitation has a sternal compression massage that compresses the heart by pressing the sternum down three to five times toward the spine. It usually refers to heart massage.

In addition, when an Automated External Defibrillator (AED) is installed around the subject, the cardiac arrest rate can be increased by performing an automatic defibrillation to the patient promptly.

First, the patient's airway is secured and the presence of respiration is checked to perform artificial respiration if breathing is stopped, and heart massage is started while artificial respiration continues if the heart is stopped. When an automatic defibrillator is provided, automatic defibrillation is performed quickly. Since such CPR is performed on the human body, it is not appropriate for the practitioner or the practitioner to repeatedly practice the above procedure.

Recently, devices for practicing artificial respiration, cardiopulmonary resuscitation, and automatic defibrillator (educational automatic defibrillator) using a manikin similar in shape to a human body are disclosed.

1 is a perspective view showing the structure of a chest modeling apparatus of a CPR simulator according to a conventional example.

1, the chest model device of the CPR simulator is provided with a vertical guide 2 inside or with a vertical guide 2 outside to prevent deformation and deformation of the cylindrical spring 1 .

In the case of such a vertical guide type guide mechanism, when the practitioner's posture is wrong, the recognition is insufficient, or the real machine is immature in the course of the chest compression practitioner being positioned on the side of the simulator and compressing the chest, Can apply the pushing force. When the horizontal force is applied to the vertical guide type guide mechanism as described above, there is a problem that the spring 1 is caught by the vertical guide 2 or the vertical guide 2 is damaged by the spring 1 .

In addition, the conventional CPR simulator only generates a sound at a certain depth with respect to the chest compression depth, or displays the light source at a certain depth or speed through the optical display device. Therefore, there is no indication about the number of training and correct number of CPR training, so the learning effect is insignificant.
