Abstract
A method that includes conveying overheated dialysate through a cassette in a manner to reduce the temperature of the overheated dialysate, and a dialysis system including a control unit configured to cause overheated dialysate to be conveyed through a cassette in a manner to reduce the temperature of the overheated dialysate.
Claims9
A method of controlling the temperature of liquid in a dialysis cassette, the method comprising:
- pumping liquid heated to a temperature greater than a desired temperature from a first pump chamber of the dialysis cassette to a second pump chamber of the dialysis cassette, wherein the first pump chamber cooperates with a first pump to pump liquid within the dialysis cassette, and the second pump chamber cooperates with a second pump to pump liquid within the dialysis cassette;
- and
- pumping the liquid from the second pump chamber of the dialysis cassette back to the first pump chamber of the dialysis cassette, wherein the liquid is pumped back and forth between the first and second pump chambers of the dialysis cassette until the liquid reaches the desired temperature.
