1. A device for measuring a bodily fluid drainage amount, the device comprising:
a measurement case which is formed of a rigid material and provided with a bodily fluid measurement space therein;
a drainage tube which is coupled to an entrance of the measurement case in a releasable structure and transfers bodily fluids discharged from a human body to the bodily fluid measurement space of the measurement case;
a plurality of fluid level sensors horizontally disposed on an upper surface of the measurement case and spaced equidistant from a center point of the upper surface, wherein the plurality of fluid level sensors measure and inform fluid levels of the bodily fluids collected in the bodily fluid measurement space,
wherein each of the plurality of fluid level sensors measures a distance between the respective fluid level sensor and the bodily fluid in a direction normal to the respective fluid sensor; and
a control device which receives and analyzes the fluid levels of the bodily fluids, infers a tilt of the measurement case from a difference in the fluid levels of the bodily fluids, and by taking the tilt of the measurement case and the fluid levels of the bodily fluids into consideration together, calculates and informs a bodily fluid drainage amount.
