17. A catheter insertion system comprising, at a first end, a distal entry port, at a second end a proximal section, a sealed catheter sleeve situated between said entry port and said proximal section, and further comprising advancing means for advancing a catheter contained within said system in a distal direction, wherein said entry port comprises a hollow body terminating at one end in a hollow cannula suitable for insertion into a peripheral blood vessel and having an internal diameter suitable for permitting passage of an intravascular catheter, and terminating at the other end with a connector element;
- wherein said proximal section comprises a hollow body having at least one external opening permitting the withdrawal and/or addition of fluid from or into the proximal opening of a catheter placed within said proximal section; and
wherein said sealed catheter sleeve is sealably connected at one of its ends to either said entry port connector element or to advancing means located between said sleeve and said entry port connector element, said sealed catheter sleeve being sealably connected at its other end to said proximal section;
such that when the aforementioned elements are connected together, a continuous hollow passageway exists from said proximal section through to the terminal portion of said hollow cannula, wherein said passageway contains the catheter that is to be inserted into a peripheral blood vessel. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
- wherein said proximal section comprises a hollow body having at least one external opening permitting the withdrawal and/or addition of fluid from or into the proximal opening of a catheter placed within said proximal section; and
-
29. A catheter insertion system comprising, a distal entry-port and advancing means for advancing a catheter contained within said system in a distal direction, wherein said entry port comprises a hollow body terminating at one end in a hollow cannula suitable for insertion into a peripheral blood vessel and having an internal diameter suitable for permitting passage of an intravascular catheter, and terminating at the other end with a connector element;
- and wherein said advancing means comprises a sealed spool containing a sterilized catheter wound around a central axis in a spiral manner, and a distal exit, such that said catheter is rolled in or out via said distal exit by rotations of the spool and wherein the lumen of said catheter can be accessed via a catheter port connected to one end of the catheter wound for permitting the withdrawal and/or addition of fluid from or into the catheter.
