Abstract
A dental anesthesia apparatus for utilization and cooperation with transcutaneous electrical nerve stimulation equipment which equipment generates low-energy electrical impulse waves to relieve pain. The apparatus includes connection members for electrical attachment to the wave generation equipment as well as provides remote switching controls to control the intensity of the generated wave being transmitted to the affected dental area. Through the remote control apparatus, the patient or the dentist himself is able to respond immediately to variations in pain to appropriately increase or decrease the intensity of the generated wave, as needed, to anesthetize the region from which the pain originates. Stainless steel electrode elements transmit the controlled impulse wave into electrode isolation media for retransmission of the generated wave through electrical conducting electrolyte solution impregnating the isolation media--all towards conducting of the desired wave output to the actual tissue area of a patient undergoing dental procedures.
