Abstract

1440027 Blood filter elements PALL CORP 14 June 1973 [16 June 1972] 28446/73 Heading B1D A blood filter element comprises, in filter flow sequence, sheet 41 of plastics netting having a pore size of about 800-about 4000 microns, sheet 42 of a mesh fabric of plastics monofilaments and having a pore size of 20-53 microns and sheet 43 of a non-woven fibrous mat having a pore size of 10-30 microns. Sheet 43 is finer than sheet 42. The element preferably has support or spacer elements 44, 45. Sheets 41, 42 may be made of polypropylene, polyethylene, polyester, polyamide or polycarbonate. Sheet 43 may be made of paper or fibres of glass or the above listed plastics. The element may be pleated. The element may take the form of a pleated pouch or bag. The elements may be used in the filter units described in Specifications 1372790 and 1334555.
