| titleOfInvention | Pump system, control unit and method for operating a pump system |
| abstract | The invention relates to a pump system (1), comprising a diaphragm fluid pump (2), which can be fluidically connected to a heart and/or at least one blood vessel by means of an inlet cannula (9) and an outlet cannula (11) and which is designed to generate a pulsatile fluid flow in order to support cardiac activity of the heart, a working pressure source (3) which is connected to the diaphragm fluid pump (2) by means of a pressure line (15) and which is designed for providing a working pressure in order to drive the diaphragm fluid pump (2), a control unit (4) designed for controlling the working pressure, a first flow sensor (21) which is designed for detecting a first cannula flow signal corresponding to an inlet flow in the inlet cannula (9) or an outlet flow in the outlet cannula (11), and a working pressure sensor (20) which is designed for detecting a working pressure signal corresponding to the working pressure in the pressure line (15), wherein the pulsatile fluid flow comprises multiple consecutive pump cycles, the cardiac activity comprises multiple consecutive cardiac cycles, and each of the pump cycles comprises a filling phase and an emptying phase. The control unit (4) is also designed to determined a time offset between a first time occurring during a first pump cycle and a second time occurring during a first cardiac cycle, to determine a haemodynamic parameter set, comprising one or more haemodynamic parameters, based on the time offset and/or the first cannula flow signal and/or the working pressure signal, and to determine a timing as a specification for a start and/or a duration of the filling phase and/or the emptying phase of the first pump cycle and/or at least one second pump cycle, occurring after the first pump cycle, based on a rule as a specification for the haemodynamic parameter set and/or for the time offset, in such a way that the rule specification is achieved. The invention also relates to a control unit (4) for a pump system (1), and to a method for operating a pump system (1). |
