Medicament preparation devices, methods, and systems

Abstract

A proportioning device includes a proportioning machine with a temperature-compensating conductivity sensor, a controller, and pump actuator. A fluid circuit is engageable with the pump actuator, has connections for a source of water and one or more medicament concentrates, and includes a mixing container. The controller is configured to mix contents of the mixing container at a first time and to sample fluid from the mixing container, to pass the samples from the mixing container through the temperature-compensating conductivity sensor at different points in time as the fluid flows from the mixing container. The controller is further configured to mix contents of the mixing container a second time if the conductivities differ by a predefined magnitude.
