A memory device stores patient-individual intradialytic parameters, laboratory parameters, and/or machine parameters, which can be used in the prognosis of patient-specific parameter progress during a dialysis treatment. | 02-12-2015 |
| 20150088047 | Monitoring Fluid Volume for Patients with Renal Disease - A method includes monitoring an indicator of fluid volume of a patient via a sensor device, and setting an initial fluid volume removal prescription for a blood fluid removal session based on the monitored indicator of fluid volume. The method may further include transmitting data regarding the indicator of fluid volume from the implantable sensor device to fluid removal device. The system includes a blood fluid removal device configured to set the initial fluid removal volume and rate prescription. In some embodiments, the fluid removal device sets or calculated the initial fluid volume removal prescription based on the data received from the implantable sensor. The indicator of fluid volume may be an indicator of tissue fluid volume or an indicator of blood fluid volume. | 03-26-2015 |
| 20160074571 | CONTROL UNIT AND METHOD FOR DETERMINING THE PRESSURE IN A BLOOD VESSEL, IN PARTICULAR IN AN ARTERIOVENOUS FISTULA - The invention relates to a control unit ( | 03-17-2016 |
| 20160121037 | ACUTE RENAL REPLACEMENT THERAPY APPARATUS - A renal therapy apparatus including at least two feedback controls is disclosed. Each control includes an estimated volume calculator to calculate an estimated volume based on a set flow, a comparator to compare the estimated volume with a measured volume, a volume deviation determining means to determine a volume deviation based on the comparison, a correction calculator to calculate a correction based on the volume deviation, a flow control generator to generate a flow control signal based on the calculated correction amount and the set flow, and a feedback control output to output the controlled flow control signal to a pump associated with each feedback control. A flow correction distributor includes an input to receive correction signals from the correction calculator, a limited correction signal calculator to calculate a limited correction signal for the input correction required signals, and an output to output each calculated limited correction signal to the feedback control from which its underlying correction required signal has been received. | 05-05-2016 |
| 20160375189 | SYSTEM AND METHOD FOR PERFORMING ALTERNATIVE AND SEQUENTIAL BLOOD AND PERITONEAL DIALYSIS MODALITIES - A dialysis system includes at least one source of fluid for dialysis, a fluid line in fluid communication with the at least one source of fluid, at least one pump positioned and arranged to pump fluid from the at least one source of fluid through the fluid line, a first patient connector configured to be removably placed in fluid communication with the fluid line to allow a blood treatment to be performed using the at least one source of fluid, and a second patient connector configured to be removably placed in fluid communication with the fluid line to allow a peritoneal dialysis treatment to be performed using the at least one source of fluid. | 12-29-2016 |
