Abstract
The invention relates to a method for introducing a catheter in a vein, comprising the following steps: puncturing the vein, introducing a guide in the punctured vein, fixing a catheter on the distal coupler of a connector, introducing a mandrel in the catheter, introducing the set formed by the catheter and the mandrel in the vein by having said set slide on the guide, withdrawing the mandrel and the guide, and connecting a fluid injection device on the second proximal coupler of the connector.
Claims18
A method for introducing a catheter in a vein comprising the following steps:
- puncturing the vein so as to form a puncturing point;
- introducing a guide in the punctured vein;
- introducing a mandrel into a connector and through a first coupler of a base, the base operatively coupled to the connector at the first coupler of the base, the connector having a catheter fixed thereto, the connector comprising a distal outlet, a first proximal inlet, and a second proximal inlet, wherein the catheter is fixed to the connector at the distal outlet of the connector, wherein each of the first proximal inlet and the second proximal inlet is in fluid communication with the distal outlet, wherein neither the first proximal inlet nor the second proximal inlet is coaxial with the distal outlet, wherein the mandrel is introduced through the first proximal inlet, through the distal outlet, of the connector and into the catheter until a distal end of the mandrel projects from a distal end of the catheter;
- introducing the catheter having the mandrel therein in the punctured vein by sliding the catheter having the mandrel therein onto the guide;
- withdrawing the mandrel and the guide;
- and
- connecting a fluid injection device to the second proximal inlet of the connector.
