PROBLEM TO BE SOLVED: To provide a disposable flow measuring machine, while a conventional measuring machine strongly affected by unsanitary urine is washed out and reused without disposal after measuring a flow rate, because it is expensive. SOLUTION: A tube is provided with a sensor for measuring the flow rate. The sensor has at least a detachable signal output portion. The signal output portion of the sensor is relatively expensive but detachable, and other portions than the signal output portion are disposable. The disposable portions include the tube to be connected directly into a human body. COPYRIGHT: (C)2004,JPO
