    摘要： The invention relates to an apparatus for carrying out a peritoneal dialysis treatment comprising a reservoir for fresh dialysis fluid, a connector for connecting to a peritoneal catheter of a patient, a drain for consumed dialysis fluid, and a control unit connected to actuators, wherein the apparatus is configured to carry out a plurality of consecutive inflow-dwell-outflow cycles for a treatment on the basis of a prescription stored in the control unit, in which inflow-dwell-outflow cycles dialysis fluid is supplied to the patient from the reservoir and is led off through the outflow again after the elapse of a specific dwell time in the peritoneum of the patient, and wherein the apparatus is further configured to already replace a portion of the dialysis fluid present in the peritoneum of the patient with fresh dialysis fluid from the reservoir before the elapse of the dwell time in at least one cycle if, in at least one preceding cycle, the volume of fresh dialysis fluid provided in accordance with the prescription for this preceding cycle was not completely consumed.

    摘要： 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.

    摘要： The invention relates to a filter device for the exchange of substances, comprising a pipe section-shaped housing with a center of gravity and with two housing ends, in which housing a hollow fiber bundle consisting of semi-permeable membranes is arranged, comprising, furthermore, an end cap having a first and second opening, wherein the housing and the end cap configure a first sealing surface which connects the housing and the end cap sealingly, and wherein the first sealing surface is spaced apart further from the center of gravity of the housing than the aperture, and wherein a first fluid chamber is formed between the first sealing surface and the first opening of the end cap, via which first fluid chamber the first opening is connected to the first flow chamber, wherein the housing and the one end cap configure a second sealing surface, wherein the first and second sealing surface are not configured by way of a sealant.
