Evan O'Neill Kane's Surgical Mask

Origin
Evan O’Neill Kane was 60 years old when he operated on himself under anesthesia, removing his own appendix; at 70, he self-operated again, this time to fix a hernia. Many of his patients were from railroad accidents and he made several medical innovations such as asbestos bandages, mica windows for brain surgery patients and a hands free lamp to work during the nighttime.

He was known to tattoo patients in later years with the letter ‘k’ in Morse code as a signature of his work. He also advocated tattooing newborns and their mothers with the same tattoo to act as a positive identification marker.

Effects
Provides an anesthesiac effect, deadening pain while keeping the wearer conscious. Also provides a slightly improved healing rate after use, allowing cuts to heal in a day and larger scars in about a week. When healing, two dark lines with a dot in the middle, the letter ‘k’ in Morse code, will appear next to cut and scar sites, then disappear within a few days.
