Abstract

1355385 Dialysis unit BAXTER LABORATORIES Inc 9 Aug 1971 [31 Aug 1970] 372666/ 71 Heading B1X A dialysis unit 14, e.g. for haemodialysis, comprises a supported flattened membrane tube 10 wound on a central core 12, and a cover 50 which has a dialysis liquid exit port having means for adjusting the pressure on the membrane. In one form this means is a rotary valve housed in the dialysis exit port, Fig. 5 (not shown). Alternatively it is in the form of a series of different diameter holes in the cover which may be selectively covered by means of a rotatable arc shaped plate, Fig. 13 (not shown). The latter form is employed when the cover 50 is in two parts viz an upper plate and a lower ring which abuts a flange on the unit 14 and which has apertures for blood flow. The plate, ring and unit flange are clamped by toggle clamps Fig. 11 (not shown), whereas adjustable screw clamps 70 are used in the Fig. 1 embodiment, see also Fig. 7 (not shown).
