摘要：
A catheter and introducer needle assembly with needle shield is provided wherein the needle includes an enlarged diameter portion and a distally facing shoulder. The needle shield includes a means for engaging the distally facing shoulder to prevent unwanted distal movement of the needle once the needle has been withdrawn into the needle shield. The needle shield also includes a small diameter opening adjacent to its proximal portion to limit proximal movement of the needle out of the needle shield.
