摘要:
The present invention provides a device for removing sweat from the inner ear by creating a vacuum in connecting tubing between the inner ear and a converging-diverging nozzle. When air enters the front of the converging-diverging nozzle, its velocity accelerates as it flows through the smaller cross-sectional area in the middle section, which causes a drop in pressure in the middle section and a resulting vacuum in the connecting tubing. This vacuum draws sweat from the bottom of the inner ear toward the middle of the converging-diverging nozzle, where it drips out of either end, resulting in sweat being removed from the inner ear.
