Human body simulation device

A human body simulation device comprising:

• an organ model that simulates an outer shape of an organ and has a liquid accommodating region to accommodate a liquid therein;
• a gas-liquid separation tank having an internal space to accommodate a gas and a liquid in a separated state;
• and
• a gas supply/suction device that supplies a gas to the internal space of the gas-liquid separation tank or sucks a gas accommodated in the internal space of the gas-liquid separation tank, wherein
• the internal space of the gas-liquid separation tank and the liquid accommodating region of the organ model are in fluid communication, allowing a liquid accommodated in the gas-liquid separation tank to flow through,
• when a gas is supplied from the gas supply/suction device to the gas-liquid separation tank, a liquid in an amount corresponding to an amount of the supplied gas is supplied from the gas-liquid separation tank to the liquid accommodating region, whereby the organ model expands, and
• when a gas is sucked from the gas-liquid separation tank by the gas supply/suction device, a liquid in an amount corresponding to an amount of the sucked gas is sucked from the liquid accommodating region to the gas-liquid separation tank, whereby the organ model contracts.
