  • Patent number: 10828411
    Abstract: An apparatus for a tidal peritoneal dialysis treatment that includes a sequence of cycles each having a filling period, a dwell period, and a drain period, includes a cycler and a processor. The cycler fills a patient's abdominal cavity with a specific inflow volume of fresh dialysis solution up to a specific patient volume in the filling period, and empties consumed dialysis solution from the cavity up to a specific tidal outflow target in the drain period. The processor controls the cycler in an operating mode such that the drain period is ended before reaching the tidal outflow target, so that a permitted residual volume remains in the abdominal cavity. A switch is made to a filling period, with the filling period being carried out such that the filling volume of the patient lies at a permitted patient volume above the specific patient volume on completion of the filling period.
