1. A suspension device for a drainage container that is used to collect aspirated body fluid, wherein the suspension device has, on a first side, a first fastening unit for mounting and fastening the drainage container on the suspension device, and wherein the suspension device has, on a second side, a second fastening unit for mounting and fastening the suspension device on a rail, wherein the first fastening unit is arranged in a first fastening part, and the second fastening unit is arranged in a second fastening part, and wherein the second fastening part has a projection which extends as far as the first fastening part and which serves to support the first fastening part in the event of a weight overload, and wherein the suspension device comprises a weighing part with a weighing element, wherein the weighing part is connectable to the first fastening part and to the second fastening part so as to measure, with the weighing element (6), a relative displacement between the first fastening part and the second fastening part (5), such that a filling quantity of the aspirated body fluid in the drainage container is determined, wherein the suspension device defines a suspension axis for the suspension of the drainage container, wherein the suspension device has a tilt sensor for determining an angle between the suspension axis and a vertical within the room in which the suspension device is located, and electronically compensating for any measuring errors of the weighing element that result from said angle between the suspension axis and the vertical based on the angle as determined by the tilt sensor.
