    Abstract: A medical fluid system includes a medical fluid pump; a container holding a fluid to be pumped by the medical fluid pump, the fluid at a first time having a first conductivity, the fluid at a second time having a second conductivity; and a radio frequency level sensor positioned in operable relation with the container, the radio frequency operation of the level sensor configured so as to be (i) indicative of a level of the fluid in the container and (ii) at least substantially independent of whether the fluid has the first conductivity or the second conductivity. The medical fluid system can determine the level of medical fluid by measuring the resistance, impedance or phase shift seen by the sensor.

    Abstract: Se proveen un sistema y método para determinar una concentración de cloro total en el agua de diálisis. El sistema comprende una unidad principal que aloja una cámara de yoduro/muestra de agua y una cámara de agente reductor. Un par de electrodos puentea las dos cámaras y genera triyoduro proporcional a la cantidad de calor total en el agua de diálisis. El par de electrodos detecta la cantidad de triyoduro generado en proporción a la cantidad de cloruro activo en el agua de diálisis. El sistema es apropiado para uso en conexión con, o para incorporación en, un sistema de purificación de agua para generar fluido de diálisis, y puede incluir una pantalla que alerta al usuario a detener o evitar un tratamiento de hemodiálisis si el nivel de cloro total excede un nivel predeterminado.
