Research on the Modeling and Micturition Performanace of Bladder Power Pump

To study the micturition performance of bladder power pump,the mathematics model of bladder power pump was built up.Based on the model,the main influence factors acting on the micturition performance of bladder power pump,such as the electromagnet current,the interval size between each permanent magnet(PM),air gap,and the numbers of PM,were analyzed.The simulation results show that the maximum vesical pressure,the maximum urinary flow rate and the average urinary flow rate are enhanced by increasing the electromagnet current and the numbers of PM,or by reducing the air gap;the maximum void volume is enhanced by increasing the interval size and numbers of PMs.Experiments were made on the simulated experimental platform,and good agreement was achieved between the experimental results and simulation results.The research provides the beneficial guidance for the optimal structure design of bladder power pump.
