The invention relates to a device for discharging wastewater, in particular used or spent dialysate, comprising a plurality of line connections 3, 4, 5 for connecting wastewater lines, in particular wastewater lines of dialysis machines. The device according to the invention is designed as a part which can stand on the bottom of a basin. Sufficient stability can be achieved on account of the weight (gravitational force) of the device alone, without it being necessary to secure the device. Recontamination is prevented effectively in that the line connections 3, 4, 5 are in fluid connection with at least one inflow line, the lower end of which is arranged so as to be spaced apart from the bottom, such that a free-fall distance is formed. In a preferred embodiment, a casing 1 surrounds the at least one inflow line 6, 7, 8.
The casing 1 forms a splash guard in the form of a hood such that the wastewater, which emerges from the inflow lines 6, 7, 8 under relatively high pressure, cannot reach the surroundings.
