Abstract
1438565 Filter series for blood PALL CORP 26 July 1973 [31 July 1972] 35751/73 Heading B1D A blocd filter has a series of two sheet filter elements arranged with the coarser element upstream of the finer. The first element is a sheet of open netting of filamentary plastics material of pore size about 800-4000 microns, and the second a sheet of open mesh plastics monofilament fabric of pore size 20-53 microns. In Fig. 1, the series is folded and gripped at two ends by tongues 27 of a plastics housing, the other sides being sealed to the housing which is made from two halves. In Fig. 4 the series is in the form of a collapsed pleated cylinder sealed in a plastics bag along the lines 52 an entry tube 55 being sealed and enclosed within the filter element series, flow being from inside to outside. The elements may be composed of polypropylene, polyethylene, polyester, polyamide or polycarbonate. The finer sheet, i.e. the second may be a woven square mesh having the filaments locked at their insections. The coarser sheet may be extruded, cast or moulded plastics having filaments joined at intersections. A support or spacer may be present between the two elements and may be of the same material as the coarse element having pores at least as large as the coarse element and within the range 800-10000 microns. The materials may be «Dacron» (RTM), Teflon (RTM), «Vexar» (RTM), «KEL-F» (RTM). The filters may be connected by Luer locks or have conduits shaped as spikes for piercing and joining into blood bags.
