Development of the Bio-signal Measurement System for Diagnosis of the Urinary Incontinence

다국어 초록 (Multilingual Abstract)

The diagnosis of the urinary incontinence is decided by medical doctor's subjective conclusion with question, physical test and urodynamic test. Therefore, they can do misdiagnosis and it is limited to objectively support the result of the diagnosis. It is necessary to diagnose exactly because of the treatment pattern have to change according to degree of urinary incontinence. In this study, it is proposed that the development of the bio-signal measurement system which is useful for quantitative index at the diagnosis of urinary incontinence by using to measure contraction pressure of the pelvic floor muscle.
The contraction pressure of the pelvic floor muscle was measured by balloon sensor and was changed electrical signal by pressure sensor. Electrical signal was transmitted to PC through the DAQ pad. In PC, GUI was composed to analyze pressure data and to extract the diagnostic parameters. Using the bio-signal measurement system that was proposed in this study, the contraction pressure data were acquired from a normal person and a stress urinary incontinence patient and numeric diagnostic parameters were extracted using developed analysis S/W. After comparing each diagnosis parameters, we can find the difference in differential pressure and pressure reducing rate. With these results, diagnostic parameters were considered that it will be able to use as the index of quantitative urinary incontinence diagnosis.
