1. A device for carrying out a tidal peritoneal dialysis treatment of a patient in a plurality of cycles, each cycle including a fill period (F), a dwell period (Dw) and a drain period (Dr), the device comprising:
- A processor;
A cycler connected to the processor and adapted to fill the abdominal cavity of the patient with dialysis fluid, and to drain the abdominal cavity; and
A sensor connected to the processor and adapted to sense during the draining a variable related to the draining of the dialysis fluid from the abdominal cavity, said variable being a pressure in the abdominal cavity of the patient during the drain period,The processor being adapted to initiate an interruption of the draining, at least for most of the cycles of the treatment, when the variable reaches a breakpoint at which the variable is radically changed, thereby leaving a residual volume of the dialysis fluid in the abdominal cavity.

Abstract
A device and a method for a peritoneal dialysis treatment having several cycles include a cycler controlled by a processor. The cycler fills the abdominal cavity with dialysis fluid, and drains the abdominal cavity. A sensor senses a variable related to the draining of the dialysis fluid. The draining is interrupted when the variable reaches a breakpoint at which the variable is radically changed, thereby leaving the residual volume of fluid.

16. A device for carrying out a tidal peritoneal dialysis treatment of a patient in a plurality of cycles, each cycle including a fill period (F), a dwell period (Dw) and a drain period (Dr), the device comprising:
-
An element for determining a first parameter associated with a desired target volume of the dialysis fluid to be contained in an abdominal cavity of the patient after each fill period of the treatment; An element for determining a second parameter associated with a total volume of a dialysis fluid to be used during a remaining part of the treatment; An element for determining a third parameter associated with a total length of time of the remaining part of the treatment; An element for determining a fourth parameter associated with a residual volume of the dialysis fluid in the abdominal cavity after the drain period; A processor adapted to calculate for a next one of said cycles via the parameters a fill volume (VF) of the dialysis fluid and a fill/dwell time including the time of the fill period and the dwell period; A cycler connected to the processor and adapted to fill the abdominal cavity of the patient with the calculated fill volume of the dialysis fluid until the target volume is reached, and to drain the abdominal cavity after the calculated fill/dwell time; and A sensor connected to the processor and adapted to sense during the draining a variable related to the draining of the dialysis fluid from the abdominal cavity, said variable being a pressure in the abdominal cavity of the patient during the drain period, The processor being adapted to initiate an interruption of the draining, at least for most of the cycles of the treatment, when the variable reaches a breakpoint at which the variable is radically changed, thereby leaving a residual volume of the dialysis fluid in the abdominal cavity.
