URINARY FLOW RATE MEASURING METHOD AND SYSTEM FOR THEREOF

摘要

A method for measuring a urinary flow rate and a system thereof are provided to obtain an effective and efficient urinary flow signal by not using a special funnel used to prevent an impact noise. A method for measuring a urinary flow rate includes the steps of: transmitting pressure of urine(113) accumulated in a container(100) to an outside of a pressure sensor(116) through a pressure transmission pipe(115); generating an electric signal as a voltage signal corresponding to a capacity signal in the pressure sensor; amplifying the electric signal through a bridge amplifier in the pressure sensor; changing the amplified analog signal into a digital signal; and deriving the urinary flow signal by a mathematical differentiation after changing the transmitted water pressure signal into a volume signal by interfacing the digital signal with an analyzing device.
