Pain-blocking bandage

摘要

A bandage to be applied adjacent to an injured portion of a patient's body contains electronic circuitry which delivers electric pulses into the body to block or mask the pain arising from the injury. The bandage includes an inner unit adapted to be applied directly onto the patient's skin and an outer unit adapted to be removably applied upon the inner unit. The inner unit includes spaced apart conductive portions which contact the patient's skin. The outer unit includes a power source and an electronic circuit which applies a voltage output to the conductive portions of the inner unit. The voltage output is transmitted through the conductive portions to the patient's skin to cause low current electrical pulses within the patient's body to block or mask the pain arising from the injury.
