         7 . The disposable according to  claim 3 , wherein the rib structure comprises at least 16 ribs distributed over the circumference of the touch-protection cover. 
     
     
         8 . The disposable according to  claim 1 , wherein the connector comprises a drip disc and a disc structure, wherein ribs are arranged between the drip disc and the disc structure, which extend at an angle between 75° and 105° to a flow-through lumen of the connector and/or are parallel to each other. 
     
     
         9 . A system comprising:
 a disposable according  claim 1 ; and   a port for establishing a fluid communication between at least one fluid line of a treatment apparatus, which fluid line is assigned to the interior of the treatment apparatus and the connector of the fluid line of the disposable, which fluid line is assigned to the exterior of the treatment apparatus, wherein the port comprises at least:
 a first fluid guide with at least a first lumen and a first end-side opening, provided for receiving and/or guiding a medical fluid and/or for establishing fluid communication with the connector; and 
 a second fluid guide having at least a second lumen and a second end-side opening; 
 wherein the first end-side opening of the first fluid guide is arranged, at least in sections, in the second lumen of the second fluid guide. 
   
     
     
         10 . The system according to  claim 9 , wherein the second end-side opening of the second fluid guide of the port has a cross-sectional area smaller than a cross-sectional area of the second lumen arranged farther towards the interior of the treatment apparatus than the second end-side opening. 
     
     
         11 . The system according  claim 9 , wherein the first lumen of the port ends in a funnel-shaped or diverging shape in the first end-side opening. 
     
     
         12 . The system according to  claim 9 , wherein an edge delimiting the first end-side opening is spaced from the inner wall of the second lumen at a distance which is at no point less than 5 mm. 
     
     
         13 . The system according to  claim 9 , wherein a length of the touch-protection cover is determined such that a front side or surface of the touch-protection cover surrounding the connection opening is guided through an inner wall of the second end-side opening or adjacent to the second lumen of the port during insertion of the connector into the second lumen of the port in such a way that it cannot come into contact with the first fluid guide. 
     
     
         14 . The system according to  claim 9 , wherein a cross-sectional area of the second lumen of the port increases starting from a cross-section, in which an opening plane of the first end-side opening of the first lumen also lies, continuously and/or steadily in an axial direction up to the beginning of an opening of the port which radially widens the second lumen in at least one cross-section. 
     
     
         15 . The system according to  claim 9 , wherein a length of the touch-protection cover and/or a distance between the free connection opening and the opening of the connector lumen are set such that a front side or surface of the opening of the connector and/or a wall of the opening cannot come into contact with the first fluid guide during insertion of the connector into the second lumen of the port. 
     
     
         16 . The system according to  claim 9 , further comprising a medical treatment apparatus, the medical treatment apparatus comprising a housing with a fastening section for connecting the medical treatment apparatus to the port 
     
     
         17 . The system according to  claim 16 , wherein the port or the fastening section comprises an edge, wherein the edge extends in a first section annularly with an inner radius, wherein a second section of the edge is not part of the annular shape having the inner radius and being formed by the first section. 
     
     
         18 . The system according to  claim 17 , wherein the connector comprises a disc structure which is round or comprises a round edge section, the disc structure comprising:
 an outer radius which corresponds to a value between 90% and 99.9% of an inner radius of the first section of the edge and/or is at most 1 mm smaller than the inner radius of the first section, and/or   wherein an outer edge section or the outer radius of the disc structure is distanced or spaced at most 1 mm away from the first section of the edge.   
     
     
         19 . The system according to  claim 18 , wherein the outer edge section or the outer radius of the disc structure is spaced or distanced at least 3 mm from the second section of the edge. 
     
     
         20 . The system according to  claim 16 , wherein the medical treatment apparatus comprises a swivel lever, arranged for its pivoting about a swivel axis, wherein the swivel lever comprises:
 a stop to temporarily prevent an axial separation movement for separating the connector of the disposable from the fastening section by or after pivoting the swivel lever into a second pivot position of the swivel lever,   
       wherein the stop is designed to limit rotation of the inserted connector about the longitudinal axis of its connector lumen.
