ABSTRACT:
A catheter introducing assembly is provided which includes a self-shielding needle while providing captured visual blood flowback. The catheter introducing assembly includes a clear Y-Connector which is used for contrast injection and has an additional port for medication. A V-Spring is placed unrestricted in a spring holder which is attached to the distal end of the Y-Connector. The spring acts as a guard, once the needle is withdrawn, to protect the needle from forward movement. An injection port is provided for high pressure introduction of medication or contrast media. A silicon ball is retained in the injection port which, when medication is required, will reseal after the needle is withdrawn. A luer/filter assembly is provided in fluid communication with the introducer needle to allow air to escape through the filter for visualization of blood flowback upon needle insertion.
