A body fluid excretion volume measurement apparatus for medical application. The apparatus stores body fluid excreted from patients in a body fluid storage tank and measures the resistance value with a resistance sensor. The resistance value depends on the shape of the body fluid storage tank, and if the tank is columnar, the resistance value is monotonically increasing with respect to the depth of body fluid. The output of the resistance sensor is processed by a measurement part and electric measurement of the body fluid volume stored in the body fluid storage tank is performed automatically.

Body fluid excretion measurement apparatus for medical application

A level sensor with an amplifier circuit includes one of the level detection resistor and the temperature compensation resistor as an input resistor or a grounding resistor to the negative input terminal of the operational amplifier, and includes the other resistor as a negative feedback resistor.
