Dental anesthetic injection device

摘要

Disclosed herein is a dental anesthetic injection device. The dental anesthetic injection device includes a laser generator, a pressure generator filled with a liquid for generating pressure, which expands due to a laser emitted by the laser generator, an anesthetic container which contains an anesthetic for dental use, a separation film disposed between the pressure generator and the anesthetic container and formed to be elastically deformable to transfer expansion energy of the pressure generator to the anesthetic container, and a replacement nozzle detachably coupled with the anesthetic container to be replaceable depending on an oral environment and configured to jet the anesthetic of the anesthetic container toward an oral cavity.

1. A dental anesthetic injection device comprising:
a laser generator; a pressure generator filled with a liquid for generating pressure, which expands due to a laser emitted by the laser generator; an anesthetic container which contains an anesthetic for dental use; a separation film disposed between the pressure generator and the anesthetic container and formed to be elastically deformable to transfer expansion energy of the pressure generator to the anesthetic container; and a replacement nozzle detachably coupled with the anesthetic container to be replaceable depending on an oral environment and configured to jet the anesthetic of the anesthetic container toward an oral cavity, wherein the laser generator generates a CO2 laser which has an energy wavelength lower than that of an erbium-doped yttrium aluminum garnet (Er:YAG) laser, and emits the CO2 laser with a wavelength of 8 um to 12 um for 1.5 seconds to 2.5 seconds, and wherein the replacement nozzle comprises a spiral flow channel to allow the jetted anesthetic to have rotational energy therein.
