Abstract:

A dialysis device for operation in multiple modes and for maintaining a known gradient of potassium ion or other electrolyte between the blood of a patient and a dialysate fluid is described. The dialysis device is capable of being used for hemodialysis or peritoneal dialysis, and the dialysis device is capable of operation with a dialysate purification unit outside of a clinical setting or with a supply of water that can be supplied in a clinical setting. The dialysis device has a composition sensor containing a potassium-sensitive electrode for measuring a potassium ion concentration in one or more of the patient's blood and the dialysate fluid and an infusate pump operated to adjust a potassium ion concentration in the dialysate fluid based at least in part on data from the composition sensor.

US Classification:

604 9, 604 8

Abstract:

An implantable dialysis device with a related medical system for intracorporeal dialysis and ultrafiltration of blood, and methods of use are described. The medical system includes an extracorporeal module, a cutaneous module, and an implantable module. Features of the implantable module facilitate delivery and flow of blood and dialysate through the medical system. A filter pack within the implantable module performs dialysis and ultrafiltration of blood. System cleansing is also described.

Abstract:

A blood based solute monitoring system for measuring at least one blood solute species that has a first recirculation flow path in communication with a dialyzer. The first recirculation flow path is configured to allow a fluid to recirculate through a dialyzer such that the concentration of at least one solute species in the fluid becomes equilibrated to the solute species concentration of the blood compartment of the dialyzer. The blood solute monitoring system has at least one sensor to measure a fluid characteristic.
