Working Principle According with the principle of weighing, utilize the high accuracy sensor and world class controlling technology. By means of microcomputer to analyze the data from sensor. It can supply speedy and convenient test of urine flow rate items. The measuring data and technology is comply with the requirement of International Continence Society (ICS.). Application It is mainly used for measuring patient’s voiding process parameter (Volume quantity, urine flow rate) and curve of process. The data will be supplied to the doctor for evaluation of patient’s lower urinary function and diagnose the lower urinary obstruction or make it as reference of treating method. Evaluate the treating effect. Clinical Advantages The different installation measuring system can be supplied by different requirement of user. The parameter will be measured automatically, intelligent measuring start, whole course urine flow rate curve, 2.0 USB interface (computer model for selection). Technical Advantages Automatically print the English Report with curve picture. Big amount of data storage (for selection) Bluetooth model (for selection) Function of data analyzing and solution.
