Abstract: A hemodialysis apparatus includes: a dialysate-delivery system including at least one unit selected from the group consisting of (i) a dialysate-preparation unit, (ii) a dialysate-circulation unit, (iii) an ultrafiltrate-removal unit, and (iv) a dialysate-monitoring unit; and a user/machine interface operably connected to the dialysate-delivery system, the user/machine interface comprising a touch screen, the touch screen including a screen having (a) a target ultrafiltration display, (b) an ultrafiltration rate display, (c) a transmembrane pressure display, (d) an arterial pressure display, (e) a venous pressure display, (f) a dialysis fluid conductivity display, and (g) a dialysis fluid temperature display; and wherein at least one of the displays of the touch screen is selectable to adjust a setting displayed by the display, the setting used to operate at least one of (i) the dialysate-preparation unit, (ii) the dialysate-circulation unit, (iii) the ultrafiltrate-removal unit, and (iv) the dialysate-monito

Abstract: A number of improvements relating to methods and apparatuses for kidney dialysis are disclosed. These include a method providing an apparatus for dialyzing to a consumer, with the apparatus including a controller for controlling a dialysate parameter, a delivery system for delivering the dialysate to a dialysate compartment of a dialyzer, and a user/machine interface having a touch screen to display an indicium corresponding to a parameter pertinent to operation of the apparatus for use in dialysis and to enable a user though touching the indicium to effect a change in the parameter. The method also includes providing supplies that are useable with the apparatus to the consumer.

Abstract: Semipermeable membranes are disclosed for purifying aqueous biological fluids. The membranes are particularly suitable for purifying extracorporeal blood via hemodialysis. The membranes, preferably configured as hollow fibers, are made from a hydrophilic polymeric material, preferably cellulose acetate. Features of the membranes include an ultrafiltration coefficient (K.sub.uF) of about 15 to about 55 mL/hr/mmHg/m.sup.2 (thus termed "high-flux" type membranes), a urea mass transfer coefficient (K.sub.oV (Urea)) of at least 38.times.10.sup.-3 cm/min, and a ratio of K.sub.oV (urea)/K.sub.uF of at least 2.5.times.10.sup.-3. Hollow fibers of such membranes suitable for hemodialysis have a lumen diameter of about 175 to about 210 .mu.m and a wall thickness of about 10 to about 35 .mu.m.
