Abstract: An infusion apparatus includes a roller assembly adapted to exert pressure on opposed sides of an IV bag to forcibly remove the fluid contents therefrom in an even and controllable manner. A sensing element mounted to the roller assembly senses the pressure exerted during the infusion operation and generates a signal to a control assembly which automatically adjusts the movement of the roller assembly in response to the pressure sensed. If the pressure sensed exceeds a predetermined level, the control assembly will activate a drive assembly to return the roller assembly to a neutral position.
