a first artificial cavity and a second artificial cavity said cavities each comprising a flexible membrane capable of beating under an action of a gas, each of said membranes sealingly separating a blood circulation chamber and a chamber containing said gas
a first gas buffer reservoir to be brought substantially to a first pressure, referred to as low pressure, and a second gas buffer reservoir to be brought substantially to a second pressure higher than said first pressure, referred to as high pressure;
a gas distribution connected to the chambers containing said gas of said first and second artificial cavities and to said first and second buffer reservoirs, arranged to alternately inject gas into said chambers containing said gas and expel gas from said chambers containing said gas to provide predetermined values of blood flow rates in the blood circulation chambers of said first cavity and said second cavity; and
a pneumatic pump supplied with electrical energy and mounted between said first buffer reservoir and said second buffer reservoir and configured to suck gas from said first reservoir in order to inject the gas into said second reservoir.
