Design and Construction of a Novel Automated and Portable Chest Compression Device

Sudden cardiac arrest and heart diseases are the leading causes of death globally, but cardiopulmonary resuscitation (CPR) may prevent multitude of death if being performed timely and accurately. Since in many cases of cardiac arrest there is not a trained rescuer and conventional CPR method is difficult and may being performed incorrectly, various equipment has been produced for this purpose. In this study, by reviewing of previous important studies on automated chest compression devices and comparing their effectiveness in returning of spontaneous circulation (ROSC), a novel, portable, programmable, flexible and automated chest compression system is introduced. For prototyping of this device, first required data were extracted from studies on CPR, then mechanical components for compression system and chassis, and electronic components for controlling unit were designed and produced. The novel device which is developed in this research could be installed easily and perform the chest compression according to the patient’s condition and guidelines automatically. It also enables chest compression even during patient transport. Furthermore, because of user-friendly design, everybody could use it easily. Eventually comparison between this device and other similar automated devices indicates that this device has more benefits and more reasonable price as well.
