Intrapericardial heart compression device

The invention discloses an intrapericardial heart compression device which comprises an injector, a guide wire and a compression device for compressing the heart of a patient, and the injector is provided with a guide wire hole allowing the guide wire to enter the pericardial cavity of the patient; the compression device comprises a balloon for pressing the heart of the patient, an air bag structure for manually inflating and deflating the balloon, an electric adjustable air pump (comprising a cam, a trapezoidal air bag, a motor and a control device) for automatically inflating and deflating the balloon, and a pipe fitting for communicating. According to the device, the unsatisfactory effect caused by traditional external chest cardiac compression and the risks of rib fracture and lung injury caused by external chest compression are avoided; according to the device, a minimally invasive puncture method is adopted to avoid trauma to the patient caused by chest wall incision of an existing intrathoracic cardiac
