Title:
METHOD FOR RECOVERING AND REGENERATING PERITONEAL DIALYZATE, APPARATUS THEREFOR, AND ATTACHMENTS THEREOF
Document Type and Number:
WIPO Patent Application WO/1997/047337
Kind Code:
A1
Abstract:
A method for regenerating a peritoneal dialyzate employed in peritoneal dialysis for treating renal insufficiency and recovered therefrom and an apparatus and its attachments thereof to be used therefor. To circulate and reuse a peritoneal dialyzate with the use of the plasma proteins of a patient himself as a colloidal osmotic agent, the discharged peritoneal dialyzate is sanitarily recovered and uremigenic factors are eliminated therefrom without denaturing the plasma proteins. At the same time, its osmotic pressure is elevated and the dialyzate is regenerated as a physiologically efficacious and safe peritoneal dialyzate in the following manner. By using a semipermeable membrane having an appropriate inhibitory fractional molecular weight, the recovered peritoneal dialyzate is concentrated to such an extent that the plasma proteins contained therein are not denatured and then diluted with a physiologically efficacious electrolyte solution. By repeating these procedures, uremigenic factors are filtered off and the excessive moisture is also removed therefrom to thereby elevate the osmotic pressure of the dialyzate. If needed, useful components such as electrolytes or amino acids are added.
