Device for electrical stimulation of deep part of human body

The utility model discloses an electrical stimulation device for a deep part of a human body. The long rubber tube is provided with a blunt round blind end, a balloon made of conductive rubber is arranged behind the blind end, the other end of the long rubber tube is blocked by a rubber air nozzle, the interior of the long rubber tube is connected with the conductive rubber balloon through a wire, and the wire is led out of the side near the open end and connected with the outside through an electrode interface. During use, the blind end is inserted into the esophagus/urethra of a human body according to a treatment part. Gas or liquid is injected through the rubber gas nozzle at the open end to enlarge the balloon, then the outer end is pinched and pulled outwards, and the balloon is considered to reach a treatment part when the balloon feels resistance and cannot be pulled. And after reaching the treatment part, the electrode is connected with a neuromuscular electrical stimulator for electrical stimulation
