Hemodialysis system including on-line dialysate generation

摘要

A hemodialysis system includes an on-line dialysate generator; a dialysate pump actuator configured to pump dialysate generated by the generator to a dialyzer; a conductivity sensor located adjacent to a temperature sensor upstream of the dialyzer; a blood pump actuator; an air detector; and a disposable cassette configured to carry dialysate pumped by the dialysate pump actuator, the disposable cassette including a conductivity sensor portion and a temperature sensor portion located to operate with the conductivity sensor and the temperature sensor, respectively, the disposable cassette further configured to carry blood pumped by the blood pump actuator and to provide an air detection portion located to operate with the air detector.
