Abstract:
An operating machine (10), such as a medical machine or a dialysis machine, includes a housing (12) for operating components of the machine and a moveable user interface or display (50) for viewing and entering information concerning operation of the machine. Signals concerning operating information are wirelessly transmitted between the machine (10) and the display (50) using one of several techniques. Power is also transmitted wirelessly from the operating machine to the screen, or from a separate power source to the display. The wireless signals may be transmitted via induction, radio, infrared or optical means.
Abstract:
A dialysis machine includes a control unit (20) having a user interface; a heater (s) located separate from the control unit; a supervisory processor located within the control unit; a delegate control processor located with the heater (s), the delegate control processor in communication with the supervisory processor and configured to receive load cell, heater (s) plate and supply bag temperature sensor inputs; and a sub-delegate heater (s) processor in communication with the control processor and configured to control power to the heater (s). The machine can also include primary and secondary monitoring processors that perform a safety check to the control processing and monitor the load cell.

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.
