The invention concerns a device and a method for a peritoneal dialysis treatment in several cycles. A cycler (1) controlled by a processor (31) fills the abdominal cavity with dialysis fluid and drains the abdominal cavity. A , sensor (37) 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.

Why it's free to use
- Filed October 13, 2004 and granted March 13, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 13, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 13, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
