MCC-E is designed to provide efficient and continuous chest compression as a supplement to manual CPR. MCC-E employed 3D compression technology which combines heart pump and chest pump theory. Compact in size (175 × 155 × 175mm) and weighing only 3.5 kilos, MCC-E is easy to carry and deploy. The metal hook is designed to fit the 3D compression band and not fall off easily. With a hole in middle, the hook can also be used as handle. The base stand is designed with four bulges for increased stability and patient comfort. The arc design on 2 sides of base reduces the risk of injury in case of local bulge in the patient's chest.
