Abstract: A dialysis fluid flow control system includes 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.

Abstract: Temperature compensation is applied to correct for temperature mismatch between a reference chamber and a disposable chamber in a pneumatic pumping system for dialysis fluid for peritoneal dialysis. The mismatch creates an error in the calculation of pumping volume of dialysate fluid. Applying a correction for the temperature mismatch helps to more precisely control the volume of dialysate that is metered to the patient. Also disclosed are ways to keep temperatures constant and to use temperature sensors to accurately measure the temperatures of the chambers. In other aspects, the temperature of the dialysate fluid itself may be measured and used to apply a correction to the volume of fluid that is pumped to the patient.

Abstract: Una compensación de temperatura es aplicada para corregir la desigualdad de temperatura entre una cámara de referencia y una cámara desechable en un sistema de bombeo neumático para fluido de diálisis para diálisis peritoneal. La desigualdad crea un error en el cálculo del volumen de bombeo del fluido dializado. La aplicación de una corrección para la desigualdad de temperatura ayuda a controlar con más precisión el volumen de dializado que es dosificado al paciente. También se describen formas para mantener temperaturas constantes y para utilizar sensores de temperatura para medir exactamente las temperaturas de las cámaras. En otros aspectos, la temperatura del mismo fluido de dializado puede ser medida y utilizada para aplicar una corrección al volumen de fluido que es bombeado al paciente.
