An artificial liver system for treating liver failure includes a reservoir to provide albumin-containing dialysis fluid to the patient's peritoneum, an implantable device including a pump to pump the fluid from the peritoneum to the bladder via respective catheters, control circuitry, battery and transceiver; a charging and communication system configured to periodically charge the battery and communicate with the implantable device to retrieve data reflective of the patient's health; and monitoring and control software, suitable for use with conventional personal computers, for configuring and controlling operation of the implantable device and charging and communication system. The monitoring and control software allows a treating physician to remotely adjust the volume, time, and frequency with which fluid is pumped from the peritoneal cavity to the bladder based on the data reflective of the patient's health.

The invention relates to a method for determining the recirculation in a fistula and / or the cardiopulmonary recirculation part during an extracorporeal blood treatment, according to which the blood to be treated flows in an extracorporeal blood circuit (I) through a blood chamber (8) of a dialyser (6) split by a semi-permeable membrane (7) into the blood chamber and a dialysis liquid chamber (9), and dialysis liquid flows in a dialysis liquid path (II) through the dialysis liquid chamber of the dialyser. The invention also relates to a device for determining the recirculation in a fistula and / or the cardiopulmonary recirculation part, and to a blood treatment device comprising a device for determining the fistula recirculation and / or the cardiopulmonary recirculation part. The method and device according to the invention are based on the fact that the sum of the fistula recirculation (RA) and the cardiopulmonary recirculation part (RCP), i.e. the total recirculation (R), is determined for two blood flow rates which differ from each other. The fistula recirculation and / or the cardiopulmonary recirculation part are then determined from the recirculation for the two blood flow rates. The first recirculation measurement is carried out for a high blood flow (QBH) for which a fistula recirculation can occur, while the second measurement is carried out for a low blood flow (QBL) for which a fistula recirculation does not occur. These two measuring values form the basis of the determination of the fistula recirculation and / or the cardiopulmonary recirculation part.

A peritoneal dialysis catheter, comprising a catheter body, a glucose monitoring probe and a strip-shaped liquid bag, one end of the catheter body is a dialysis area, and a plurality of dialysis holes are opened on the dialysis area, the other end is connected to an external dialysis fluid bag, and the catheter body is provided with a dialysis hole One end of the strip-shaped liquid bag is connected with the glucose monitoring probe, and the strip-shaped liquid bag is set in the inner cavity of the catheter body, and the length is not less than the length of the dialysis area on the catheter body. The catheter body is connected to one end of the external dialysate bag, and a rubber stopper is provided at the opening of the liquid injection port. The invention has the advantages that the peritoneal dialysis catheter does not float, has good sealing performance, does not block the dialysis hole, and can monitor the glucose concentration of the dialysate in the peritoneal cavity in real time.

The invention concerns a device and a method for a peritoneal dialysis treatment in several cycles. A cycler (1) controlled by a processor (31) fills the abdominal cavity with dialysis fluid, and drains the abdominal cavity. A sensor (37) senses a variable related to the draining of the dialysis fluid. The draining is interrupted when the variable reaches a breakpoint at which the variable is radically changed, thereby leaving the residual volume.
