THE ANESTHESIA INHALER- MEDICAL INNOVATIONS OF THE CIVIL WAR
Illustration: The Chisolm Pocket Ether or Chloroform Inhaler byTiemann
Dr. Julian John Chisholm invented a 2.5 inch inhaler, the first of its type. Chloroform was dripped through a perforated circle on the side onto a sponge in the interior; as the patient inhaled through tubes, the vapors mixed with air. This new method required only one-eighth of an ounce of chloroform, compared to the old two-ounce dose.
The usual method of soaking a handkerchief with chloroform wasted the liquid as it evaporated.
