ABSTRACT:
An apparatus for circulating a purge solution in an artificial organ has an ultrafiltration filter or reverse osmosis filter in a purge solution circulation route to inhibit passage of substances having molecular weights of 340,000 or more. A portion of the purge solution circulated by a purge solution circulation pump is passed through this filter to remove proteins that have mixed in the purge solution. The purge solution free from the proteins is supplied and circulated through the artificial organ. Proteins that have externally mixed in the purge solution can be prevented from coagulating and depositing on a seal mechanism and the like of the artificial organ.
