A dual port syringe has an upper port for connection to a fluid reservoir and a lower port for delivery of the medical fluid under pressure to a patient. A first valve is connected between the fluid reservoir and the upper port, and second valve is connected between the lower port and the patient. During a fill operation, a piston is moved within the syringe to drawn fluid from the reservoir into the syringe through the upper port. During injection operation, the piston moves in an opposite direction to force fluid out of the syringe through the lower port.

A control device for controlling a fluid supplying machine. The control device includes a first handle and a second handle connected by a resilient attachment member. The resilient attachment member is configured to allow the first handle to move with respect to the second handle in response to an input from an operator. The control device further includes a sensor attached to the first handle for producing a variable control signal indicative of a distance between the first handle and the second handle.
