Simulation and Experiments for Urethral Valve Driven by Ultrasonic-vaporized Steam

Abstract

Abstract:

Aiming at the problem of severe urinary incontinence caused by urethral sphincter dysfunction, a urethral valve driven by ultrasonic-vaporized steam was presented herein. The mathematical model of urethral valve was built based on the theories of ultrasonics, thermodynamics and magnetism. The effects of ultrasonic control parameters on driving performance of urethral valve was studied by simulation and experiments. The opening/closing performance of urethral valve was verified by experiments. The results show that the principle of urethral valve is feasible and mathematical model is simple and effective; the driving performance of urethral valve is improved by increasing ultrasonic intensity, radiation area and frequency; the opening/closing performance of urethral valve is good.

Key words: urethral valve, ultrasonic, driving performance, opening/closing performance
