Embodiment Construction

[0038] The universal dialysis device 2; 2'; 2"; 2"" has a peristaltic pump 4; 4'; 4"; 4"" on the front side for pumping blood and dialysate. The dialyzer 6; 6'; 6"'; 6"" is arranged near the pump 4; 4'; 4"; 4"". During operation, the dialyzer 6; 6'; 6"; 6"" is connected on the one hand to the dialysis device 2; 2'; 2"; 2"" and on the other hand to the patient. One of the pumps 4; 4'; 4"; 4"" delivers the blood to be purified to the dialyzer 6; 6'; 6"'; 6"". The other of the two pumps 4; 4'; 4"; 4"" delivers the dialysate to the dialyzer 6; 6'; 6"'; 6"". In order to be able to operate the dialysis device 2; 2'; 2"; 2"", a monitor 8; 8'; 8"; 8"", preferably realized as a touch screen, is arranged on the front side of the dialysis device. In order to ensure a stable and upright position of the dialysis device 2; 2'; 2"; 2"" on the horizontal plane, the dialysis device has a base part 10; 10'; 10"'; 10"" on the underside. Also for ease of transport, castor wheels 12; 12'; 12";...

Abstract

The invention relates to a dialyzer (6; 6'; 6''; 6''') for extracorporeal blood treatment having an elongate dialyzer housing (14; 14'; 14''; 14'''; 14'''') and at least one dialysis membrane (30; 30'; 30''; 30'''; 30''''), which divides an interior of the dialyzer housing (14; 14'; 14''; 14'''; 14'''') into a dialysis fluid chamber (32; 32'; 32''; 32'''; 32''''), which has a dialysis fluid supply connection (44; 44'; 44''; 44'''; 44'''') and a dialysis fluid discharge connection (46; 46'''), and a blood chamber (38; 38'; 38''; 38'''; 38''''), which has a blood supply connection (40; 40''') and a blood discharge connection (42; 42'; 42''; 42'''; 42''''). The dialyzer has an additional ventilation outlet (48; 48'; 48''; 48'''; 48'''') for ventilating the blood chamber (38; 38'; 38''; 38'''; 38''''), which is formed on the dialyzer housing (14; 14'; 14''; 14'''; 14'''') on or near an end face thereof. The additional ventilation outlet (48; 48'; 48''; 48'''; 48'''') is provided in the blood discharge connection (42; 42'; 42''; 42'''; 42'''') between an outlet area (58; 58'; 58''; 58'''; 58'''') of the blood discharge connection (42; 42'; 42''; 42'''; 42'''') and the dialysis fluid supply connection (44; 44'; 44''; 44'''; 44''''), in respect of a blood flow direction (Bo; Bo'; Bo''; Bo'''; Bo''''). The invention further relates to a corresponding dialysis apparatus (2) having a ventilation outlet (48; 48'; 48''; 48'''; 48'''') provided on a dialyzer housing (14; 14'; 14''; 14'''; 14'''') or on a hose (62'''') connected to a blood discharge connection (42'''').

Description

technical field [0001] The invention relates to a dialyzer for extracorporeal blood treatment, comprising: an elongated dialyzer housing; at least one dialysis membrane which divides the inner space of the dialyzer housing into two dialysate ports The dialysate chamber and the blood chamber provided with two blood ports. The invention also relates to a dialysis device comprising such a dialyzer. Background technique [0002] Known dialyzers generally have four ports, via which the dialyzer can be connected on the one hand to the line system of the dialysis machine and on the other hand to an extracorporeal blood system connected to the patient. The aforementioned ports are divided into two ports for connection to the extracorporeal blood system or blood circulation, via which the blood to be purified is conveyed to and from the dialyzer, which ports are hereinafter also referred to as the blood supply port and the blood discharge port and two ports for connection to a dial...
