Patent number: 7351340Abstract: 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.Type: GrantFiled: June 13, 2003Date of Patent: April 1, 2008Assignee: Baxter International Inc.Inventors: Mark E.

Patent number: 5736046Abstract: 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.Type: GrantFiled: November 20, 1996Date of Patent: April 7, 1998Assignee: Althin Medical, Inc.Inventors: Anders Althin, Ben Fernandez, Raymond Elsen, Kees Ruzius, Lalith Silva, George Washington
