FIELD: medical equipment.
SUBSTANCE: auxiliary circulation pump includes a preload-sensitive element located in a sealed cavity of the straightener assembly and/or an afterload-sensitive element located in a sealed cavity in the diffuser assembly. Each of these sensitive elements is connected to a control system. The control system is configured to convert preload and afterload into pump flow and control the pump motor, adjusting, depending on the data received from the preload-sensitive element and/or from the afterload-sensitive element, the speed of rotation of the impeller to control cardiac output.
EFFECT: providing the possibility of complete or partial replacement of the pumping function of the heart in a manner sensitive to preload and/or afterload.
