Abstract
A system and method for providing slow dialysate flow with an intermittent hemodialysis delivery (IHD) system are disclosed. The system includes a dialysate slow-flow fluid pump having an outlet for connection to an inlet port of a hemodialyzer and an inlet for connection to a dialysate bulk flow line in association with the IHD. The system further includes an outlet line for coupling an outlet port of the hemodialyzer back to the dialysate bulk flow line, wherein the dialysate slow-flow fluid pump is configured to control the rate of delivery of dialysate to the hemodialyzer.
Claims29
An adaptor for providing slow dialysate flow with an intermittent hemodialysis (IHD) delivery system, the adaptor comprising:
- a dialysate slow-flow fluid pump;
- said pump having an outlet for connection to an inlet port of a hemodialyzer and an inlet for connection to an on-line generated dialysate bulk flow line in association with an IHD delivery system;
- and
- an outlet line for coupling an outlet port of the hemodialyzer back to the dialysate bulk flow line;
- wherein the dialysate slow-flow fluid pump is configured to control the rate of delivery of dialysate to the hemodialyzer.
A hemodialysis system for variably providing slow dialysate flow for continuous renal replacement therapy (CRRT) and high flow for intermittent hemodialysis (IHD) delivery, the system comprising:
- a hemodialyzer;
- a dialysate bulk flow line for use in association with an IHD delivery system;
- a dialysate slow-flow fluid pump;
- said pump having an outlet for connection to an inlet port of the hemodialyzer and an outlet for connection to a dialysate bulk flow line;
- and
- an outlet line for coupling an outlet port of the hemodialyzer back to the dialysate bulk flow line;
- wherein the dialysate slow-flow fluid pump is configured to control the rate of delivery of dialysate to the hemodialyzer.
A method for providing slow dialysate flow with an intermittent hemodialysis (IHD) delivery system, the method comprising:
- coupling an inlet of a dialysate slow-flow fluid pump to an on-line generated dialysate bulk flow line in association with an IHD delivery system;
- coupling an outlet of the dialysate slow-flow fluid pump to an inlet port of a hemodialyzer;
- coupling an outlet port of the hemodialyzer back to the dialysate bulk flow line;
- and
- controlling the rate of delivery of dialysate to the hemodialyzer.
