Abstract
Methods, device, and systems for preparing peritoneal dialysis fluid and/or administering a peritoneal dialysis treatment are disclosed. In embodiments, peritoneal dialysis fluid is prepared at a point of use automatically using a daily sterile disposable fluid circuit and one or more long-term concentrate containers that are changed only after multiple days (e.g. weekly). The daily disposable may have concentrate containers that are initially empty and are filled from the long-term concentrate containers once per day at the beginning of a treatment.
