A "Duplex Oxygenator" (.1a), a fraudulent medical device created by Edvard L. Moses in 1909. The closed, nickel-plated tube connected to coiled straps purported to contain "Contact Disks" which increased oxygen flow to a patient or purchaser. The patent-medicine device was debunked in 1913 by scientists who determined that it contained only coke dust or carbon black, and Moses served federal prison time for wire fraud as a result. Oxygenators were sold in aluminum containers with ornate raised labeling (.1b).
