Apparatus for treating ascites
First Claim
1. An apparatus for treating ascites including protein and contaminated with at least one member of the group consisting of blood, cancer cells and bacteria, said apparatus comprising:
- (a) an ascites introducing means for carrying ascites from a body into said apparatus;
(b) an ascites transporting means coupled to said introducing means for supplying the force to carry said ascites through said apparatus;
(c) a first filter means for removing bacteria and cancer cells from said ascites, said first filter means including at least one first membrane means for allowing protein to pass therethrough and for blocking the passage of bacteria, cancer cells and other substances of similar size;
(d) a hemolysis preventative means coupled between the output of said transporting means and the input of said first filter means for removing air bubbles from said ascites whereby hemolysis caused by the mixture of air bubbles with the filtered ascites is prevented;
(e) an ascites concentrating means, coupled to the output of said first filter means, said ascites concentrating means including a second membrane means for passing substances of a size different than the size of the substances passed by said first membrane means for blocking the protein in said ascites to thereby form a protein concentrated ascites;
(f) ascites discharging means, coupled to said ascites concentrating means, for receiving said protein concentrated ascites and returning said protein concentrated ascites to the body.

Abstract
An apparatus for treating ascites which is safe and superior in performance and does not cause hemolysis, by removing harmful bacteria or cancer cells contained in ascites, by filtration, concentrating useful proteins, etc. contained therein and returning the resulting concentrate to living body is provided.
Said apparatus comprises an ascites-transporting means, a hemolysis-preventive means connected to said ascites-transporting means, a filter for removing bacteria and cancer cells, containing at least one membrane for filtering the ascites which has passed said hemolysis-preventive means, and a concentrating vessel containing at least one membrane for concentrating the ascites thus filtered.
