Design and investigation of bladder power pump driven by an external electromagnet
Xiao Li,Ting Guan,Dongcai Zhou,Chunbao Liu 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.9
This study aims to evaluate the feasibility of the bladder power pump driven by an external electromagnet proposed by the authors. The structure of the pump was designed based on its working principle. The mathematical model and 3D finite element model of theelectromagnetic field of the pump were established. The electromagnetic driving property of the pump was analyzed using the models,and the micturition performance of the pump was investigated in the simulated experimental system. Results show that maximum intravesicalpressure and maximum urine flow rate reached 10.8 KPa and 13.9 cm³/s, respectively, approaching the normal human urodynamicparameters. This novel pump has the potential of being used for assisting neurogenic bladder micturition.
