摘要:
A device and methods for extracorporeal treatment of fluids, such as blood, for effective plasmafiltration or hemofiltration alone or in combination with dialysis. The preferred devices (10) is a circuit that may include a dialyzer (20), a plasmafilter (30), a sorbent pump (40) to circulate a treatment sorbent solution, a sorbent container (32), and a leak detector (50) may be located downstream from the filtration member.

The present invention relates generally to advantageous devices and methods for treating patients suffering from renal insufficiency and/or hepatic insufficiency. More particularly, the invention relates in certain aspects to devices and methods for performing continuous flow-through peritoneal dialysis (CFPD). In other aspects of the invention, peritoneal dialysis systems are provided which utilizes a bioreactor to regenerate peritoneal fluid for re-infusion into a peritoneal cavity. The invention, therefore, provides advantageous systems for passing fluid through a patient's peritoneal cavity at a relatively high flow rate, while maintaining in the peritoneal cavity an optimal dialysate pressure, to thereby alter the contents of the patient's blood by diffusion of molecules through the peritoneal membrane.

The invention relates to methods and compositions for delivering iron to an iron-deficient patient, more particularly, to methods whereby an iron complex comprising divalent or trivalent ionic iron complexed with one or more low molecular weight anions is administered to a patient by transfer from dialysate. A complex selected according to the invention is non-polymeric; soluble in an aqueous medium; chemically stable, thereby preventing the dissociation of iron ions from the anions under conditions according to the invention; and can be well absorbed into blood and the living body. Also provided are dialysate compositions including therein an iron complex selected according to the invention, and dialysate concentrates which may be diluted to yield an inventive dialysate composition.

Devices and methods for providing extracorporeal treatment of blood for effective plasmafiltration or hemofiltration are disclosed. The device incorporates a hollow fiber membrane device (HFD) connected in series with a parallel plate dialyzer (PPD). Sorbent suspension from a sorbent bag (101) first passes through the sorbent inlet (102) of the PPD, exits through sorbent outlet (103), is drawn into accumulator reservoir (104), is expelled from accumulator reservoir (104) and passes through check valve (105) in response to alternating positive pressure and negative pressure applied to the accumulator reservoir (104). The sorbent suspension then passes into HFD inlet (106) and through the outer chamber of the HFD, thus agitating and mixing the sorbent suspension into contact with exterior surfaces of the hollow fibers (107) in the HFD. Sorbent suspension exits the HFD from outlet (108) and passes through blood leak detector (109) and back into the sorbent bag (101).

Method and device for extracorporeal treatment of blood to effectively remove toxins therefrom and from patients are disclosed. The method includes the steps of passing the blood and dialysate through a plate dialyzer (30) comprising a blood inlet (39), a blood outlet (40) and a dialysate inlet (29), a dialysate outlet (35) and the blood side is separated from the dialysate side by dialyzer membranes. The method also includes passing a sorbent suspension through dialysate side and applying alternating negative pressure and positive pressure on the dialysate side of the dialyzer via an accumulateur (22) to expand and contract dialyzer membranes and agitate the sorbent suspension to prevent settling and mix it to maintain chemical gradients across the membrane. A positive pressure gradient is maintained throughout the cycle from the blood side to the dialysate side of the dialyzer.
