Medical Facilities and their Practioners of the Worlds' Greatest Heroes

Both the Justice League and Justice Society were prepared for all contingencies, and this included medical emergencies from cases that endangered their members. As such, each team had specially designed and equipped medical facilities within their headquarters.

While the Justice Society had the advantage of two physicians on staff, Doctor Mid-Nite aka Doctor Charles McNider and Doctor Fate aka Doctor Kent Nelson (the former of whom helped save the life of the latter, after a battle with Vulcan Son of Fire), the Justice League did not have a dedicated medical professional. However, both teams had a Wonder Woman, each equipped to perform life saving techniques (such as when the Earth-One Wonder Woman saved her teammate Aquaman). 

Besides standard Earth-based state-of-the-art medical devices, the teams' members also incorporate their own technology. The League used Thanagarian devices to revive the Flash. The Society relied on the stellar based technology of Ted Knight, aka Starman, to help sustain the life of Doctor Fate. On an earlier occasion, the Earth-Two Wonder Woman revitalized six of her teammates in the Society with her purple healing ray, a scientific breakthrough she and her counterpart invented individually.
