  • Publication number: 20190015800
    Abstract: Systems and apparatuses for preparing a medical fluid are disclosed. In an example embodiment, a system is configured to initially control a dosing of a first concentrate, while not feeding a second concentrate, under feedback control via a concentration sensor to a first pump to feed the first concentrate. When a concentration has reached a preselected concentration level, a value for a feeding parameter for the first pump to feed the first concentrate is determined. Additionally, the system is configured to control the dosing of both the first and the second concentrates by switching the feedback control via the concentration sensor, from control of the first pump to control of a second pump to feed the second concentrate. During this time, the system controls the first pump to feed the first concentrate based on the determined value of the feeding parameter.
