Yeni bir yüksek ivmeli göğüs kompresyon cihazının tasarımı ve simülasyonu

Cardiopulmonary Resuscitation (CPR), a method of medical intervention for Cardiac Arrest, requires effective chest compressions that provide blood flow to vital organs. The recommended technique for CPR according to the American Heart Association (AHA) guidelines is standard manual CPR. However, many different mechanical CPR technologies have been developed in recent years, to achieve more consistent chest compression. Although these technologies can achieve the manual CPR parameters described in the AHA guidelines, they have not yet been proven to be superior to manual CPR. A potential explanation for why machines have not been able to be superior to humans is initial momentum. The human upper body mass can be a good source of momentum during manual CPR, and chest compression with high initial momentum can provide more effective blood flow. In this study, a novel CPR device with a special piston mechanism capable of high initial momentum and high acceleration chest compression consisting of a double slider-crank and dynamic conrod is developed. To enhance the transfer of high acceleration on the piston to the chest, a more rigid skeletal structure has been designed in comparison to the existing CPR devices. The displacement, velocity, and acceleration values obtained from the motion simulation of the designed piston mechanism on the chest model exhibited consistency when compared with the results obtained from the mathematical model. The same simulation results are compared with the experimental realization results of LUCAS-2 and Corpuls devices obtained from another study and it is confirmed that the proposed mechanism had higher initial momentum and acceleration.
