Narrative:

On a recent training flight with my student; we experienced a near collision with a helicopter while operating in the traffic pattern. We had been practicing landings on the right runway at our local airport. Near the end of the lesson; we decided to switch to the left runway because it would result in a much shorter taxi to the ramp area. We requested the runway switch with the control tower while on the upwind leg; and he approved the transition. He then instructed us to turn crosswind for the parallel runway. Shortly after; he called us back with an urgent tone telling us to climb to an altitude 500 ft above traffic pattern; and informed us that there was a helicopter operating between the parallel runways. Before we could respond; he instructed us to 'climb climb climb'. We never saw the helicopter; but we identified him with our ads-B [automatic dependent surveillance - bravo] equipment on our mfd screen. He passed approximately 400 ft directly below us.
