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.

Methods for providing kidney dialysis equipment and services

A number of improvements relating to methods and apparatuses for kidney dialysis are disclosed. These include checking of dialysate bypass status using flow measurement; using a flow sensor to confirm the absence of ultrafiltration during bypass; automatic testing of ultrafiltration function by removal of a discrete volume from a portion of the dialysate flow path coupled with a pressure test of that part of the flow path; using a touch screen user interface; bar graph profile programming of ultrafiltration, sodium, and bicarbonate parameters; using a RAM card to upload treatment instructions to, and to download treatment data from, the machine; automatic setting of proportioning mode (acetate or bicarbonate) based on connections of concentrate lines; predicting dialysate conductivity values based on brand and formulation of concentrates; minimizing no-flow dead time between dialysate pulses; initiating operation in a timed mode from a machine power-off condition; preserving machine mode during machine power-fail condition; calibration scheduling and reminding; automatic level adjusting; and blood leak flow rate detecting.

Method and apparatus for kidney dialysis

A number of improvements relating to methods and apparatuses for kidney dialysis are disclosed. These include methods such as supplying a dialysis machine including a touch screen interface to a machine user and supplying to the machine user accessory devices to be used with the dialysis machine in operation.

A novel class of bioreactor apparatuses are disclosed which offer improved performance over prior art designs. The apparatuses circulate nutrient fluid through a bioreactor device, such as a hollow fiber bioreactor cartridge, which is used to culture a colony of cells. The nutrient fluid is refreshed by the controlled addition of fresh fluid and the controlled removal of used fluid through a sterile infusion/extraction device. Cellular by-product yield is enhanced by periodically alternating the direction of nutrient fluid through the bioreactor and by periodically circulating the harvest fluid through the extracapillary region of the bioreactor cartridge.
