Abstract: A valve assembly embodiment includes first and second valve devices and a coupling mechanism. Each of the first and second valve devices can include first and second fluid pathways and first and second valve members respectively positioned at the first and second fluid pathways. Both the first and second valve members can have an open position that permits fluid flow and a closed position that prevents fluid flow along the first and second fluid pathways past the first and second valve members. The coupling mechanism can couple to each of the first and second valve members. When the valve assembly is actuated, the coupling mechanism can be configured to transition one or both of the first and second valve members between the open and closed positions.

Abstract: A hand-control device for controlling the operation of an injection system is described herein. The hand-control device includes one or more input components that receive input to control various operations of the injection system, including commanding the injection to perform a particular operation, changing an operational aspect of the injection system, and selecting an operational mode for the injection system. A communication unit of the hand-control device generates and conveys a signal for the injection system, and receives a command signal from the injection system. An output component outputs an indication, such as a light emission, a sound, or haptic feedback, in response to receiving the command signal. In some instances, this indication acts as a confirmation or failure of the intended input.
