Abstract: The degasser can have a degassing membrane that can be constructed from non-porous silica. The degassing membrane can be highly permeable to carbon dioxide but less permeable oxygen or nitrogen gases. Pressure in the dialysate and the degasser can be controlled in order to control the amount of carbon dioxide and other gases in dialysate leaving the degasser. The degassing membrane may be placed in a degassing module in a dialysate flow path to remove dissolved carbon dioxide from the dialysate.

Abstract: 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.

Abstract: Devices, systems, and methods for high capacity degassing of dissolved gases and gas bubbles from fluid such as a dialysate are provided. The devices, systems, and methods can include a degassing vessel with at least two degassing chambers. The fluid can be degassed in a first degassing chamber and recirculated through a second recirculating degassing chamber to remove a desired amount of gas such as carbon dioxide.

Abstract: The invention relates to devices, systems, and methods for priming, disinfecting, and preparing dialysate and related fluids for use in dialysis. The dialysate and related fluids can be prepared from solutes obtained from infusate containers seated in an infusate caddy. The infusate caddy can be removably positioned in a receiving compartment of a dialysis machine. Similarly, the infusate containers containing the necessary solutes for preparing the dialysate and related fluids can also be removably positioned in the infusate caddy.

Abstract: The invention relates to devices, systems, and methods for calculating a bicarbonate concentration in a fluid used in dialysis. The devices, systems, and methods can be used to calculate the bicarbonate concentration in either dialysate or blood. The invention measures the amount of carbon dioxide in both an acidified and non-acidified solution and calculates the bicarbonate concentration based on the difference in carbon dioxide concentrations.

Abstract: The degassing system can include a degassing vessel and can utilize a vacuum pump and a fluid pump located downstream of the degassing vessel to control the pressure within the degassing vessel in order to control the concentration of gases in fluid exiting the degassing system. The degassing system can further comprise sensors in communication with the pumps to control the rate of flow and pressure through the degassing system. The degassing system may be placed in a dialysate flow path to remove dissolved gases including carbon dioxide from the dialysate.

Abstract: An arterial air capture chamber (101) is used in dialysis. The arterial air capture chamber (101) includes an upwardly extending fluid inlet (102) terminating in a fluid inlet port (105) positioned at about a 90° turn relative to a fluid flow of a fluid inlet tube (107). The arterial air capture chamber (101) includes a draw tube (104) with an opposedly positioned beveled opening (306) at about 180° relative to the fluid inlet port (105). The arterial air capture chamber (101) provides improved fluid dynamics, reducing both stagnant flow and turbulence. The arterial air capture chamber (101) also provides for bidirectional flow of fluid through the arterial air capture chamber (101).

Abstract: A flow loop for hemodialysis, hemodiafiltration and hemofiltration for the treatment of pathological conditions such as End Stage Renal Disease (ESRD) that has a controlled compliant flow path for preparing fluids required for a hemodialysis therapy session from water. The controlled compliant flow path modifies water into any one of a solution for priming a hemodialysis system, a physiologically compatible solution for contacting blood, a physiologically compatible solution for infusion to a subject, and a solution for blood rinse back to a subject. The controlled compliant flow path has a means for selectively metering in and metering out fluid from the flow path.
