  • Publication number: 20220218886
    Abstract: A renal failure blood therapy system includes a memory device storing a therapy target for a patient. The system also includes a processor configured to receive the therapy target for the patient, receive a desired solute concentration for the patient, and apply the therapy target and the desired solute concentration as inputs to an optimization routine. The processor is also configured to execute the optimization routine to determine at least one dialysis therapy prescription specifying at least a dialysis therapy duration, a dialysis therapy frequency, and at least one of a dialysis therapy blood flow rate or a dialysis therapy dialysate flow rate. The processor is further configured to display the at least one dialysis therapy prescription for confirmation or selection by a clinician and transmit the selected or confirmed dialysis therapy prescription to a dialysis machine for a subsequent dialysis treatment for the patient.

  • Patent number: 9629949
    Abstract: A renal failure blood therapy system includes a renal failure blood therapy machine, a test including multiple blood samples taken at multiple times during a test therapy to determine concentration levels for each of a first solute and a second solute at each of the multiple times, and a device programmed to (i) estimate at least one first patient parameter using the determined concentration levels for the first solute, (ii) estimate at least one second patient parameter using the determined concentration levels for the second solute, (iii) determine a first plurality of acceptable treatments using the at least one first patient parameter, (iv) determine a second plurality of acceptable treatments using the at least one second patient parameter, and (v) merge the first plurality of acceptable treatments with the second plurality of acceptable treatments to determine a plurality of clinically acceptable treatments for both the first solute and the second solute.

  • Patent number: 9132219
    Abstract: A method of predicting serum potassium concentrations in a patient during hemodialysis includes measuring serum potassium concentrations of the patient over a hemodialysis treatment session time and an ultrafiltration rate calculated by a difference between pre- and post-dialytic body weight of the patient during an initial hemodialysis treatment session divided by a total treatment time of the treatment session and estimating a potassium mobilization clearance and a pre-dialysis distribution volume of potassium for the patient. Serum potassium concentrations of the patient can then be predicted at any time during any hemodialysis treatment session with the estimated potassium mobilization clearance and pre-dialysis distribution volume of potassium of the patient.

  • Patent number: 8975240
    Abstract: Peritoneal dialysis solutions including a glucose polymer and methods of using the dialysis solutions are disclosed herein. In a general embodiment, the peritoneal dialysis solution includes a glucose polymer in an amount to provide an increased ultrafiltration fluid volume for a given amount of carbohydrate absorbed compared to conventional dialysis solutions containing icodextrin as the active pharmaceutical ingredient. The increased ultrafiltration fluid volume for a given amount of carbohydrate absorbed is obtained by providing specific combinations of weight-average molecular weight, polydispersity index and concentration of the glucose polymer in the dialysis solution.

  • Patent number: 8868350
    Abstract: A method of predicting serum phosphorus concentrations in a patient during hemodialysis includes measuring serum phosphorus concentrations of the patient over a hemodialysis treatment session time and an ultrafiltration rate calculated by a difference between pre- and post-dialytic body weight of the patient during an initial hemodialysis treatment session divided by a total treatment time of the treatment session and estimating a phosphorous mobilization clearance and a pre-dialysis distribution volume of phosphorus for the patient. Serum phosphorus concentrations of the patient can then be predicted at any time during any hemodialysis treatment session with the estimated phosphorous mobilization clearance and pre-dialysis distribution volume of phosphorus of the patient.
