Self-Administered Anesthetic (Feb, 1952)

Self-Administered Anesthetic
Medical and dental patients can administer a mild anesthetic to themselves with a bulb-operated instrument designed to relax nervous tension. The instrument fits over the patient’s nose. In his hand he holds the rubber bulb which administers the analgesic. When he relaxes he automatically stops pumping the bulb but can resume pumping at any time. The relaxed stage lasts from 1 to 1 1/2 minutes and leaves no ill effects.
