Anesthesiology Reflections From The Wood Library-Museum
From Syracuse, New York, on July 26, 1889, William L. Tucker applied for a U.S. Patent for counterirritation, applying an inflammatory irritant (e.g., camphor or menthol) at one site to reduce inflammation or pain at another. Tucker described his technique as follows using most of the numbers on his patent diagram (left): after unscrewing the removable “cap  from the tube, I insert the non-medicated sponge  into the mouth of the tube, leaving a portion of it protruding from the top. I then force air through the mouth-piece  and [flexible] tube 3, causing a [vapor] current to pass through the medicated sponge , thereby charging it with the irritant. This protruding part of the sponge I apply to the flesh or skin.” Just over 9 months after submitting his (patent) application for (irritant) application, Tucker was granted U.S. Patent No. 426,609 for his “Apparatus for Applying Irritants.” The Wood Library-Museum’s example (right) is marked with “VAPOR / COUNTER IRRITANT / PAT. APRIL 29TH 1890.” (Copyright © the American Society of Anesthesiologists, Inc.)
