An O'Dwyer pediatric intubation set complete with seven intubation tubes in graduated sizes, an
introducer, a tube extractor, and a Denhardt's mouth gag, all contained in a fitted metallic case. The set is nickel plated brass
except for the tubes which are gold plated. The cover for the tubes indicates the sizes by age, ranging from the smallest for use on
children of 1 yr, up to the largest for 10-12 year-olds. It is further marked Pat. July 12, 1892, Pending, GEO. ERMOLD, NY. The
extractor is also marked Ermold. The set shows general signs of use and wear but is in good overall order, and the instruments are
each in good working order. The case is 3 1/2" x 9".
Joseph O'Dwyer developed this apparatus between 1880 and 1887 in order to prevent diphtheria patients from suffocating due to the
growth of a false membrane over the larynx which occurs in severe cases of the disease. Diphtheria was the most feared of all
childhood diseases. One child out of every ten that became infected died from this disease. As a last resort, these tubes were
inserted into the larynx and thus maintain air supply until the crisis period of the illness passed.
A good description of the apparatus can be found in The Mechanics of Surgery by Charles Truax.
