Technical

“Divinyl ether was used extensively following the recommendation of Samuel Gelfan and Irving Bell, of Edmonton, in1933 that it be used as an anesthetic. It could be given by open administration from a dropper or by a semiclosed administration with a Goldman in haler and later by a modified version known as the Oxford Vinethene. For use in dental surgery, the Oxford Vinethene inhaler was attached to a mask placed over the nose. A one-way inlet valve for air x operated only if the breathing bag became empty and it allowed the patient to breathe in fresh air; expired air passed into the bag and a bypass device allowed the anesthesiologist to gradually increase the concentration of Vinethene.” (ref.1)
