Hemodialysis System With Variable Dialysate Flow Rate
US Patent:
2022038, Dec 8, 2022
Filed:
May 28, 2021
Appl. No.:
17/334393
Inventors:
- Irvine CA, US
Tzu Tung Chen - Irvine CA, US
Clayton Poppe - Irvine CA, US
Tzu Tung Chen - Irvine CA, US
Clayton Poppe - Irvine CA, US
Assignee:
DIALITY INC. - Irvine CA
International Classification:
A61M 1/16
A61M 1/38
B01D 46/00
A61M 1/38
B01D 46/00
Abstract:
A portable hemodialysis system is provided including a dialyzer, a closed loop blood flow path which transports blood from a patient through the dialyzer and back to the patient, and a closed loop dialysate flow path which transports dialysate through the dialyzer. Preferably, the hemodialysis system includes a sorbent filter in the dialysate flow path. Furthermore, the hemodialysis machine includes a blood pump, and a pair of dialysate pumps. A processor controls the flow of blood through the blood flow path, and the processor controls the flow of dialysate through the dialysate flow path. In addition, the processor stores a patient treatment plan wherein the flow rate of the dialysate through the dialysate flow path reduces throughout the patient's treatment to maximize the amount of urea removed by the sorbent filter.
Dialysis System With A Dialysate Quality Sensor
US Patent:
2022037, Dec 1, 2022
Filed:
May 27, 2022
Appl. No.:
17/827506
Inventors:
- Irvine CA, US
Tzu Tung Chen - Irvine CA, US
Clayton Poppe - Irvine CA, US
Tzu Tung Chen - Irvine CA, US
Clayton Poppe - Irvine CA, US
International Classification:
A61M 1/16
Abstract:
A portable hemodialysis system is provided including a dialyzer, a closed loop blood flow path which transports blood from a patient through the dialyzer and back to the patient, and a closed loop dialysate flow path which transports dialysate through the dialyzer. Preferably, the hemodialysis system comprises a sorbent filter in the dialysate flow path. Furthermore, the hemodialysis system comprises a dialysate quality sensor disposed directly in the dialysate flow path. The dialysate quality sensor is configured to change color based on a pH level, ammonia level, or ammonium level of the dialysate.
Sorbent Regeneration Cartridge For Dialysis
US Patent:
2022037, Dec 1, 2022
Filed:
May 26, 2022
Appl. No.:
17/825805
Inventors:
- Irvine CA, US
Tzu Tung Chen - Irvine CA, US
Tzu Tung Chen - Irvine CA, US
International Classification:
A61M 1/16
B01J 20/02
B01J 20/28
B01J 20/02
B01J 20/28
Abstract:
Sorbent regeneration systems for use in dialysis machines are described. Sorbent regeneration cartridges may include a layer of urease, a layer of acid zirconium phosphate, and a layer of sodium zirconium phosphate. An apparatus for conducting dialysis may include a sorbent cartridge, and a dialyzer in fluid communication with the sorbent cartridge, wherein spent dialysate passes from the dialyzer to and through the sorbent cartridge, and wherein the sorbent cartridge comprises a layer of urease, a layer of acid zirconium phosphate, and a layer of sodium zirconium phosphate. The urease may be immobilized to or associated with a carrier.
Methods And Systems For Controlling Dialysate Salt Concentration
US Patent:
2022037, Dec 1, 2022
Filed:
May 27, 2022
Appl. No.:
17/827578
Inventors:
- Irvine CA, US
Tzu Tung Chen - Irvine CA, US
Clayton Poppe - Irvine CA, US
Tzu Tung Chen - Irvine CA, US
Clayton Poppe - Irvine CA, US
International Classification:
A61M 1/16
Abstract:
A portable hemodialysis system is provided comprising a dialyzer, having a dialysate-replenishing system for replenishing minerals of dialysate in the dialyzer, the dialysate-replenishing system includes: a sorbent filter configured to remove ammonia from the dialysate, the sorbent filter having an outlet that outputs the dialysate to a dialysate flow path; a first reagent source containing a first reagent solution; a first pump configured to inject the first reagent solution into the dialysate flow path; a first mixer coupled to the dialysate flow path and downstream of the first pump, the first mixer configured to mix the dialysate with the first reagent solution; a conductivity sensor configured to measure a level of dissolved solids in the dialysate after the first mixer; and a controller configured to adjust a flow rate of the first reagent solution by adjusting the first pump based at least on the level of measured levels.
