Anti-infection catheter

An anti-infection catheter arrangement comprising:

• a catheter exhibiting
• a rigid or flexible catheter tube having a connection piece disposed
• at a rear side end;
• a filling and suction device having a plurality of reservoirs of active agent and connectable to the connection piece,
• wherein a first one of the active agent reservoirs is filled with a substance, containing a member selected from the group consisting of antibiotic, chemo-therapeutic agent, anti-viral agent and mixtures thereof in an at least minimum effective concentration,
• wherein a second one of the active agent reservoirs is filled with a second substance containing or forming at least one essentially non-damaging material to the tissue cells and blood cells,
• wherein the filling and suction device is constructed such that the second substance essentially can be filled into the region of the tip of the catheter tube to provide a buffer such that the substance, containing a member selected from the group consisting of antibiotic, chemo-therapeutic agent, anti-viral agent and mixtures thereof does not enter into the blood, and
• wherein the total volume of the reservoirs is larger than the filling volume of the catheter.

An anti-infection catheter arrangement comprising:

• a catheter tube having a connection piece disposed at a rear side end of the catheter tube;
• a filling and suction device having
• a first reservoir filled with a first agent containing a member selected from the group consisting of antibiotic, chemo-therapeutic agent, anti-viral agent and mixtures thereof in an at least minimum effective concentration;
• a first membrane fixedly disposed in the filling and suction device and closing the first reservoir and separating a connection from the first reservoir to the connection piece;
• a second reservoir filled with a second agent containing or forming at least one essentially non-damaging material to the tissue cells and blood cells;
• a second membrane closing the second reservoir and separating a direct connection from the second reservoir to the connection piece;
• a push rod determining the boundaries of the first reservoir and capable of pressing open the first membrane and capable of pressing open the second membrane such that initially the second agent enters into the catheter tube and only thereafter the first agent enters into the catheter tube.
