THE INSTRUMENT FOR LOCAL ANESTHESIA OF ORAL CAVITY BY IONOSPHORESIS

摘要

The present invention relates to an oral topical anesthesia device by iontophoresis.;Conventional oral anesthesia was mainly used for syringes, but it gave a fear to the children and evenly anesthesia and the anesthesia time was not long, there was a problem that the injection of the anesthetic repeatedly.;The present invention forms an electrode support frame made of a non-conductor material in the same form as a local anesthetic site to correct the conventional problems, and forms an electrode incorporating gold or aluminum foil on the inner surface thereof, thereby applying lidocaine solution to the anesthetic site. After absorbed cotton wool was filled in the electrode, current density 0.25mA / ㎠ and current 3mA were applied to the electrode for 1 ~ 10 minutes to allow the drug to penetrate into the tissue by the repulsive force between the ions of the drug and the electrode so that it could be uniformly anesthetized. will be.
