Cardiocirculatory aiding device, as hematic pumping device able to aid the right or left ventricular or biventricular of the human body, characterised by being supplied by gas pneumatic energy, in which: i) the variation of pressure generator device systems is intended for being placed outside of the human body; ii) the pumping device of the blood (P), is conceived to be installed inside of the human body; iii) the two said devices (i,ii) are connected with at least one tubular duct of transmission of said gas, passing from the inside of the human body to the external of the same; iv) said pumping device of the blood (P) being driven by the variation of pneumatic pressure in said duct by means of two opposite expansible and retractable lungs that compress a central chamber body elastically yielding by pulses in order to cause, by means of two ducts respectively of blood entry and blood exit with unidirectional valves, the pumping of the blood. |
