• EXPERIMENTAL STUDY ON THE INFLUENCE OF PRESSURE FLUCTUATION IN THE DRAINAGE STACK PIPE SYSTEM ON THE MEASUREMENT PERFORMANCE INDICATORS FOR TOILETS WITH AN UROFLOWMETER

抄録

In medical institutions including hospitals, it is an essential examination procedure to collect data of outputs and flow rates of patients' urine for ensuring correct health management and diagnosis. This study proposes a method for testing the performance of a toilet with an uroflowmeter, which is developed for this very purpose, when the toilet is installed to a stack system, and examines how effective the method may be according to the results, with the intention of clarifying the variation of pipe pressure allowable when the toilet is installed to a drainage ventilation system.<br> To be more specific, this study discusses the following points: 1. the examination of how effective the abovementioned method may be for testing the performance of the toilet by applying the previously proposed method for testing the combined drainage performance of the house drain; 2. the examination of the influence of pipe pressure variations, which are caused by applying drainage loads using the aforementioned test method, on the accuracy of performance indicators, such as urine outputs, the maximum urine flow rate, urine flow curves; and finally, on the basis of the results acquired, the range of variation of pipe pressure allowable in the design of drainage and ventilation pipework is clarified.
