Description

[0001] A MANNEQUIN FOR PRACTICING CARDIOPULMONARY RESUSCITATION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mannequin for cardiopulmonary resuscitation training, and more particularly, to a mannequin for CPR training to provide visual / auditory feedback in response to chest compression.

Cardiopulmonary resuscitation is a first-aid treatment that artificially circulates blood and assists in breathing when a heart attack occurs. Cardiopulmonary resuscitation is a crucial factor in circulating blood even when the heart is paralyzed, delaying brain damage and restoring the heart from paralysis. It is reported that if a person who witnessed a heart attack immediately undergo CPR, the probability of saving lives for a heart attack patient is three times higher than that without CPR. In addition, cardiopulmonary resuscitation has been found to be 3 times as likely as cardiac arrest survival in patients with cardiac arrest. It is expected that everybody will learn CPR, and if it is done effectively in an emergency situation, it will save lives of many heart attack patients.

During cardiac arrest, the heart is in a state of non-airtight cardiac contraction (fibrillation) or complete arrest, which prevents blood from flowing into the brain or other vital organs, including the heart itself. In the United States alone, over 300,000 deaths occur per heartbeat per year. It is the purpose of CPR to prevent blood and oxygen from flowing into the heart and brain to prevent damage until the patient's heart rate can be restored. The simplest form of CPR, i.e., manual CPR, involves two cycles of ventilation, followed by a manual cycle of chest compressions of 15.75 to 5 cm depth at a rate of 100 compressions per minute.

Generally, a mannequin for practicing such a CPR is formed of a material having a predetermined elastic force to simply perform compression, or a head portion and a body portion are simply connected to each other to practice airway assurance.
