Finite element modeling and experimental analysis of bladder volume body surface monitoring method

Bladder dysfunction seriously affects people’s quality of life. The accumulation of urine volume in the bladder changes the bladder volume, which changes the impedance of the hypogastrium. This paper constructs a finite element model of the hypogastrium and bladder, and the impedance of the hypogastrium at different volumes of the bladder is obtained by simulation. It also explains the causes of bladder impedance changes based on the current density distribution and designs the impedance acquisition circuit to carry out experimental data measurements on the subjects. The results show that changes in bladder volume affect the amplitude and phase of impedance in the hypogastrium. The model proposed in this paper can provide a theoretical basis for bladder urine volume body surface monitoring.
