Patent Images
1. A dialysis fluid flow control system comprising:
- a pumping cassette interface including a pump area operable with a pump chamber of a disposable cassette;
the cassette interface further including a volumetric reference chamber used in a volumetric control of a dialysis fluid pumped pneumatically into and out of the pump chamber of the disposable cassette;
a heater connected operably to the cassette interface; and
a controller connected operably to the heater so as to cause the heater to heat at least a portion of the cassette interface to a desired temperature.
