Oxydonor

The Oxydonor "Victory" (or simply Oxydonor) is a gas-pipe device, originally manufactured and sold by Hercules Sanche from the late nineteenth century into the early twentieth. The device was marketed as an instrument for oxygen therapy, promising to make the wearer "oxygen positive" through a process described as "thermo-electric induction" or diaduction that would "polarise" the body, and is essentially the same product as Sanche's Electropoise, albeit shorter in length and containing a quantity of carbon.
