A Bladder Power Pump Driven by External Electromagnet and Simulated Experimental System

This paper presents a bladder power pump driven by the external electromagnet. It is an electromagnetic power device for assisting the bladder micturating, which is composed of magnetic mover, stator, and external electromagnet. Based on the structure and micturition mechanism of human bladder, the working principle of the pump was proposed, and the structure of main parts of the pump was designed. According to the similitude criterion of fluid dynamics, the experimental system for simulating the fluid environment of urine in the urinary system was designed. This research lays the experimental foundation for analyzing and studying the working principle and dynamic characteristics of the pump. This will provide the beneficial referrences for developing the new auxiliary micturition device to solve the puzzle of the neurogenic bladder.
