A study of measurement performance evaluation for toilet systems with an uroflowmeter in hospital facility

The voided volume of urine or the uroflowmetry of the patients are routinely examined in urology department of healthcare facilities in order to diagnose urinary system diseases or manage systemic metabolism. Conventional uroscopy has several problems. Patients often suffer mental anguish with a sense of shame on ground that they discharge their urine and leave it in the public eye at inspection rooms. Nurses have heavy workload with the preparation of urine sampling or disposal after clinical examination. Medical doctors may run a risk of occurrence of hospital infection unless the urine is properly disposed. Toilet with an uroflowmeter is evaluated in hospital facility in this study. We demonstrated the effectiveness of the calibration system in experimenting on the drainage load before and after the completion. As results, the toilet system can measure the characteristics of urine of the patients precisely during their usual defecation under within ±200Pa of the jurisdiction pressure fluctuation in loop ventilation method of SHASE-S206. We designed and developed the first reliable toilet system with an uroflowmeter to measure the voided volume of urine or the uroflowmetry in the world. It is found that the toilet in actual healthcare facilities can solve most problems of conventional uroscopy according to our availability for hundreds of clinical uses. The toilet system as medical equipment saved the load of the nurses and brought comfort to the patients.
