1. A method for processing protein-containing ascites fluid from a body comprising:
- passing the protein-containing ascites fluid to a first filter having a pore rating for the removal of cells in the fluid, andthen filtering the protein-containing cell-depleted fluid through a skinless positively charged microporous hydrophilic membrane having a pore rating less than the rating of the first filter to produce a protein-containing fluid for infusion into the body.

Abstract
A protein-containing fluid, for example, ascitic fluid is removed from a patient by paracentesis. The fluid is held in a reservoir and filtered by a plasmapheresis filter and a positively charged nylon membrane before being in a condition for return to the body. This filtration is designed to remove componants such as cells, cell fragments, fibrin, endotoxins and other particulate contaminations from the ascitic fluid and thus to reduce the incidence of fever and other unwanted side effects.

11. A method for processing ascites fluid containing plasma proteins and cells comprising:
-
filtering the ascites fluid to separate plasma protein-containing fluid from cell-containing fluid; removing a pyrogenic substance from the separated plasma protein-containing fluid by passing the fluid through a skinless positively charged microporous hydrophilic membrane. - View Dependent Claims (12, 13)
