Abstract

Hemoperfusion columns packed with active charcoal and a synthetic resin have been manufactured in Czechoslovakia since 1983. In both cases the sorption packings are coated with a layer of poly (2-hydroxyethyl methacrylate). The columns are manufactured in two sizes: for adults (800 m1) and for children (400 m1). The manufacturer is OPS Kolín: the number of columns manufactured so far is 3400.

Columns

The column is made by welding four parts (Fig.1) obtained by means of a plastic moulding press from health-safe polypropylene (Mosten 52 492). The space of the column body is separated from its end with polypropylene sieves. The sorbents are thoroughly purified and free from all toxic and irritating admixtures. Their particles are coated with hydrogel. Sterilization takes place at 125°c for 2 h in an autoclave. Sorbents used for industrial purposes are based on active charcoal from coconut shells and on the styrene-divinylbenzene resin Amberlite XAD-2 and XAD-4.
