Abstract
The present invention concerns a multipart fluid system for dialysis therapy, wherein the multipart fluid system comprises an anticoagulation fluid and at least one treatment fluid from the group consisting of dialysis fluid and infusion fluids. According to the invention the anticoagulation fluid comprises 15-40 mM citrate; and the at least one treatment fluid comprises 1.5-8 mM citrate and ≧10 mM bicarbonate. The present invention further concerns a system for citrate anticoagulation in an extracorporeal blood circuit.
Claims20
A multipart fluid system for dialysis therapy, said multipart fluid system comprising an anticoagulation fluid and at least one treatment fluid from the group consisting of dialysis fluid and infusion fluids, characterized in that
- said anticoagulation fluid comprises 15-40 mM citrate;
- and
- said at least one treatment fluid comprises 1.5-8 mM citrate and ≧10 mM bicarbonate.
A system for citrate anticoagulation in an extracorporeal blood circuit comprising an arterial blood line configured to be connected to a vascular access for withdrawing blood from a patient and a venous blood line configured to be connected to the vascular access for returning blood to the patient, the system comprising:
- a filter with a dialysate side and a blood side;
- which blood side is in fluid communication with the arterial and venous blood lines;
- and which blood side is in fluid communication with an anticoagulation fluid source comprising 15-40 mM citrate;
- a treatment fluid source comprising 1.5-8 mM citrate and ≧10 mM bicarbonate, and said treatment fluid source being in fluid communication with at least one of the blood side or dialysate side of the filter.
