The apparatus for controlling the bio-mechanical ventricle-aorta matching of a patient is intended to provide quantities of medical gas at a controlled pressure to a balloon (1), or other inflatable intra-aortic device, through a catheter (2) introduced in the arterial system of the patient. The apparatus includes: a damping bag (20), of greater volume than that of the balloon (1 ), adapted to be loaded with medical gas at a compliance pressure (Pc) and placed in direct fluid communication with the balloon (1). The damping bag (20) is kept in direct fluid communication with the balloon (1) for the entire duration of the treatment of said patient. The apparatus further includes: a maximum pressure reservoir (10) that can be filled with medical gas at a maximum pressure (Pm) to in turn fill the damping bag (20) at the compliance pressure; compliance pressure detecting means (21) in the damping bag (20); connecting means (25) between the damping bag and the catheter (2), provided with operable compliance flow shutoff means (26); a control unit (50). |
