Abstract
A first drive unit, in a state where a top end of a tubular joint is interposed into a chest of a target person and is located at a lower heart part, pushes a diaphragm out from the top end of the tubular joint while pressing a gas into the diaphragm, and simultaneously causes the diaphragm to start flexing to cover and wrap the lower heart part, and then stops pressing the gas into the diaphragm at a time point where compression balloons are positioned at atriums and ventricles of a heart, respectively; and second drive units support a pumping function of the heart by alternately repeating an ejecting operation to fill each of the compression balloons with a fluid and cause each compression balloon to expand and an absorbing operation to cause each compression balloon to discharge the fluid and contract.
