<P>PROBLEM TO BE SOLVED: To provide a catheter and introducer needle assembly with a compact needle shield. <P>SOLUTION: The introducer needle includes an enlarged diameter portion. The needle shield is disposed inside the catheter hub. The needle shield includes a transverse barrier to prevent unwanted distal movement of the needle once the needle has been withdrawn into the needle shield.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 proximal opening to limit proximal movement of the needle out of the needle shield. <P>COPYRIGHT: (C)2010,JPO&INPIT |
