Abstract

1451701 Dialysis apparatus BAXTER LABORATORIES INC 1 Feb 1974 [8 Feb 1973] 04679/74 Heading B1X A diffusion device such as a dialyser comprises a plurality 'of stacked plates separated by membranes so as to define a first set of flow paths between adjacent membranes and a second set of flow paths across the plates, each plate having a profiled membranesupporting surface provided with a plurality of rows of spaced projections which support a corresponding overlying membrane, each membrane being stretched in one direction over the projections, the centre-to-centre spacing of the projections in said one direction being greater than the centre-to-centre spacing of the projections in a direction transverse to said one direction. The stack may be bracketed between pressure plates and enclosed in a pair of hollow shells. The membranes may be of cellulose and the device may be used for haemodialysis or blood oxygenation.
