    摘要： A pH-buffer measurement system that has at least one source for modifying the pH of a fluid entering the system, the source selected from an acid source and a base source. The acid source adds an acid equivalent to provide an acid reacted fluid and the base source adds a base equivalent to provide a base reacted fluid. The source is in fluid communication with a flow path and a component for determining a fluid characteristic of the acid reacted fluid or the base reacted fluid. The fluid characteristic that is measured is any one of a gas phase pressure, an electrical conductivity, or thermal conductivity.

    摘要： Apparatuses, systems, and methods for the performance of kidney replacement therapy having or using a dialyzer, control components, sorbent cartridge, and fluid reservoirs configured to be of a weight and size suitable to be worn or carried by an individual requiring treatment are disclosed. The system has a controlled compliance dialysis circuit, where a control pump controls the bi-directional movement of fluid across a dialysis membrane. A first sorbent cartridge is provided for use in a portable treatment module having activated carbon and zirconium oxide. The system also provides for the monitoring of an inlet and outlet conductivity of a sorbent cartridge containing urease to provide a facility to quantify or monitor the removal of urea by a detachable urea removal module.

    摘要： Systems and methods for the performance of kidney replacement therapy having or using a dialyzer, control components, sorbent cartridge and fluid reservoirs configured to be of a weight and size suitable to be worn or carried by an individual requiring treatment are disclosed. The system for performing kidney replacement therapy has a controlled compliance dialysis circuit, where a control pump controls the bi-directional movement of fluid across a dialysis membrane. The dialysis circuit and an extracorporeal circuit for circulating blood are in fluid communication through the dialysis membrane. The flux of fluid moving between the extracorporeal circuit and the dialysis circuit is modified by the rate at which the control pump is operating such that a rate of ultrafiltration and convective clearance can be controlled. The system provides for the monitoring of an inlet and outlet conductivity of the sorbent cartridge to provide a facility to quantify or monitor the removal of urea by the sorbent cartridge.

    摘要： 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.
