Description

CPR practice device with pressure control}

The present invention relates to a pressure-adjustable cardiopulmonary resuscitation practice device, and more particularly, to a pressure-adjustable CPR practice device that can be easily practiced by children as well as adults because the pressure can be adjusted according to the subject of practice.

Cardiopulmonary resuscitation (CPR) is an emergency treatment that artificially circulates blood and assists breathing in the event of a heart attack. The basic steps of CPR include checking the patient's state of consciousness, checking for help and reporting to 119 by loudly asking for help when it is confirmed that he is unconscious, and checking whether breathing is abnormal or not. Respiration check step to determine the pulse, pulse check step to check the pulse of the carotid artery, chest compression step to compress the heart of a patient whose heart has stopped, tilting the head to prevent airway obstruction due to tongue muscle relaxation, securing airway by lifting the chin Step, artificial respiration, in which air is blown into the lungs of a patient whose breathing has stopped, and then chest compressions and artificial respiration are repeated until paramedics arrive on the scene.

In particular, when a heart attack occurs, attempting CPR within 4 minutes is important in determining the survival probability, and brain damage begins after 4 minutes as it drops by 10% for every 1 minute delay. Therefore, when performing CPR, the exact compression location, compression strength, number of compressions, and ventilation volume become the most important.

Patent Documents 0001 and 0002 have been proposed in relation to devices for CPR training and practice.

Patent Document 0001 relates to a chest model device of a CPR simulator in which chest compression practice can be performed under conditions similar to those of the actual human body by using the vertical motion of a spring and the rotational motion of a link mechanism.

Patent Document 0002 relates to a cardiopulmonary resuscitation training device that can be placed in various spaces while having mobility or portability and can acquire a constant compression speed.

The CPR training devices of Patent Documents 0001 and 0002 have the advantage of being easy to carry, but the pressure of compression cannot be adjusted according to the subject of practice, so there is a difficulty in separately manufacturing adult, child, and youth according to the pressure of compression.
