P10884-IL1 | 298182/2 PERITONEAL DIALYSIS SYSTEM FIELD OF THE INVENTION id="p-1" id="p-1" id="p-1" id="p-1" id="p-1"
id="p-1"
[0001] The present invention, in some embodiments thereof, relates to a systems, devices and methods for dialysis treatment.
BACKGROUND id="p-2" id="p-2" id="p-2" id="p-2" id="p-2"
id="p-2"
[0002] Peritoneal Dialysis is a lifesaving procedure for removing waste and excess water from the blood. It is used primarily to sustain the health of patients who have experienced renal failure. id="p-3" id="p-3" id="p-3" id="p-3" id="p-3"
id="p-3"
[0003] The peritoneal dialysis removes wastes and excess water from the blood inside the body using the peritoneum as a natural semipermeable membrane. Wastes and excess water move from the blood, across the peritoneal membrane, and into a special dialysis solution, called dialysate, in the abdominal cavity and more specifically the peritoneal cavity. The waste materials that are removed include uremic wastes, excess water, and excess minerals.
