ABSTRACT:
An intravascular catheter or cannula assembly including a catheter device having a catheter tube and a catheter hub, and a cannula device having a cannula and a cannula hub. A cannula positioning rod is securely mounted on the cannula hub through a fixing member. A stopper is securely mounted on the catheter hub to abut against the distal end of the rod, thereby regulating the projecting length of the cannula from the distal end of the catheter tube when the cannula is inserted into the catheter tube. A member having a groove is provided to prevent an axial movement of the cannula. The groove tightly and detachably receives the fixing member and the stopper thereby integrally holding the catheter device and the cannula device when they are assembled.
