This disclosure relates to sorbent bags that is used in the purification and regeneration of a dialysis solution. Each sorbent bag comprises a sorbent material in a reinforced plastic sealed portion with luer extensions and clamps to facilitate the inlet and outlet of the dialysate solution and to facilitate the mechanism of operation. Furthermore, each sorbent bag has recharge/reactivation line with luer and a vent line. The recharge/reactivation line with luer is located at the inlet line of the sorbent bag at its distal portion before a porous portion. While a vent line is located at the outlet line of the sorbent bag after a second porous portion. Each sorbent bag has shape that is gradually increased in diameter until a diameter “D” and then gradually decreased in diameter through the remaining length of the bag in the direction of the fluid flow.

Disclosed are apparatus and methods for blood and other biological fluid purification using a membrane with cell containing vascular channel systems and filtration channel systems. Also disclosed are methods of making the apparatus as well as methods of making membranes.

The present invention relates to a computer system (1) for setting adjustment values of a blood treatment apparatus (100), comprising a first input interface (I1), a second input interface (I2), as well as an output interface. Furthermore, having a calculation device (5) and a display device (I3), whereby the calculation device (5) is programmed, after reading a target value for the renal dose via a blood treatment apparatus (100), to display to the user in a graphic via the display device (I3), a selection range (A) from a number of combinations (K1, K2, K3), each of exactly one adjustable value, (Q;.sup.⋅.sub.1, Q;⋅.sub.2, Q;⋅.sub.3) for the flow of the blood pump (101), on the one hand, and precisely one adjustable value ({dot over (D)}1, {dot over (D)}2, {dot over (D)}3) for the flow of the dialysis liquid pump (121), on the other. Based on the displayed selection range A, the user can select one of the displayed combinations via a second input interface (I2). The calculation device (5) is further programmed so that the adjustable value (Q;.sup.⋅.sub.B) for the blood pump (101) and the adjustable value ({dot over (D)}.sub.B) for the dialysis liquid pump (121) of the selected combination (K.sub.B) can be given via the output interface.

The present invention relates to a method for preparing a macromolecular composition comprising phenylglyoxaldehyde-derivatives. The invention also relates to the macromolecular compositions per se, and to methods of using the macromolecular compositions. The macromolecular compositions are useful for undergoing subsequent reactions with small molecules, for instance to remove such small molecules from a solution.

The disclosed device, systems and methods relate to a novel catheter, system and methods. Exemplary embodiments comprise a plurality of lumens and balloons for insertion into the aorta and vena cava.

A process for removing Sr.sup.2+ toxins from bodily fluids is disclosed. The process involves contacting the bodily fluid with an ion exchanger to remove the metal toxins in the bodily fluid, including blood and gastrointestinal fluid. Alternatively, blood can be contacted with a dialysis solution which is then contacted with the ion exchanger. The ion exchangers are represented by the following empirical formula:
A.sub.mZr.sub.aTi.sub.bSn.sub.cM.sub.dSi.sub.xO.sub.y. A composition comprising the above ion exchange compositions in combination with bodily fluids or dialysis solution is also disclosed. The ion exchange compositions may be supported by porous networks of biocompatible polymers such as carbohydrates or proteins.

A blood treatment machine includes a patient comfort feedback mechanism configured to be adjusted by a patient to indicate comfort levels of the patient. The machine is configured to adjust one or more treatment parameters based on the patient feedback.

Dialysis systems and methods for operating dialysis machines (e.g., peritoneal dialysis machines) for conducting dialysis treatments are disclosed. The dialysis system may include a dialysis machine for transferring dialysate to a patient from a dialysate source. The dialysate may flow from the dialysate source through a cartridge or cassette (e.g., a disposable cartridge or cassette) positionable within the dialysis machine. The cassette includes a fluid flow channel. The dialysis machine includes a heating chamber for in-line heating of the dialysate in the fluid flow channel. The fluid flow channel is arranged and configured to provide turbulent flow of the dialysate through the fluid flow channel to provide increased heat transfer from the heating chamber to the dialysate.
