Apparatus for performing peritoneal ultrafiltration

An apparatus for conducting ultrafiltration using a peritoneal membrane of a patient, the apparatus comprising:

• a patient tube comprising a connector for connection to a patient line for access to a peritoneal fluid installed in a peritoneal cavity of the patient;
• an intermittent bag connected to said patient tube;
• a flow pump for removal of a portion of said peritoneal fluid via said patient tube in an outflow of fluid from the peritoneal cavity into the intermittent bag and for return of contents of said intermittent bag in an inflow of fluid from the intermittent bag to the peritoneal cavity;
• a glucose bag, comprising concentrated glucose solution;
• a glucose tube connecting said glucose bag to said patient tube;
• and
• a glucose pump arranged in said glucose tube for addition of concentrated glucose solution from said glucose bag into said outflow of fluid, such that the concentrated glucose solution is diluted and included in the inflow of fluid to the peritoneal cavity to intermittently replenish the peritoneal fluid installed in the peritoneal cavity with glucose that causes the ultrafiltration to be conducted.
