Abstract
A system for mixing a batch of medicament has a pump actuator, control valve actuators, a source of concentrate, and a purified water source, all connected by a fluid circuit. A controller controls various control valves to open fluid channels from the source of concentrate and from the purified water source to connect a junction of the fluid circuit to the concentrate container and the purified water source. The controller also controls the pump actuator and a water pump to flow water and concentrate through the junction into a mixing container, such that the mixture of the concentrate and the water requires additional dilution to form a ready-to-use medicament. The controller samples the mixture and calculate an additional quantity of water to add based on the sampling.
