Abstract:

The present disclosure relates to devices and methods for neutralizing an acidic anesthesia solution. An anesthesia neutralization device includes an outer housing and an inner housing. The inner housing holds a buffer carpule and an anesthetic carpule in a side by side arrangement, with the buffer solution maintained under pressure prior to deployment. A curved transfer needle is coupled to the outer housing and includes ends that both point respectively toward the buffer carpule and anesthetic carpule. The device is actuated by moving the inner housing relative to the outer housing to bring the anesthesia carpule and buffer carpule into contact with the transfer needle and to force buffer solution through the transfer needle and into the anesthesia carpule.
