AUTOMATIC CANNULATION DEVICE

摘要

An improved intravascular catheter placement device (92), as shown in fig.11, for the automatic insertion of intravascular catheter (106) into the interior of blood vessels comprising a needle (94), an intravascular catheter (106) concentric to the needle, and self-propelling means (146) for moving said catheter (106) into a blood vessel (88) upon needle penetration of the wall (89) of the blood vessel (88). The self-propelling means is actuated by means for sensing penetration of a blood vessel.
