Ghost trap

In the Teenage Mutant Ninja Turtles/Ghostbusters crossover, a ghost trap is a device commonly used by the Ghostbusters to imprison ghosts temporarily, until they can be disposed of in the ecto-containment unit.

When Chi-You was turning hockey players into his thralls, Winston Zeddemore attempted to suck him into a trap while the Turtles and other Ghostbusters kept him distracted. However, he was temporarily immune to the trap, since the connections to his thralls kept him free.

Eventually they were able to imprison Chi-You in a ghost trap, and Zeddemore subsequently threw it through the interspatial teleporter, where it was left floating 4.2 light-years from Earth.
