Method of forming IV catheter and needle assembly
First Claim
1. A method of forming a needle assembly comprising:
- providing a cannula having a sharp distal end and a proximal end;
crimping the proximal end to seal the proximal end;
inserting the cannula into a needle hub such that the proximal end of the cannula is disposed in a glue well of the needle hub;
inserting glue into the glue well; and
curing the glue.

Abstract
An IV catheter includes a catheter having a wall defining a lumen, a proximal end, and a distal end. An adapter has a proximal end, a distal end and an internal cavity. The adapter is in fluid communication with the catheter lumen. A septum is positioned within the adapter cavity at the adapter proximal end. An extension tube extends laterally from the adapter and is in fluid communication with adapter cavity. A tip shield has a distal end, a proximal end and an internal cavity. The tip shield is positioned adjacent adapter proximal end and coaxially aligned with adapter. A hub has a proximal portion, a distal portion and an internal cavity. The hub is positioned adjacent the tip shield proximal end and is aligned coaxially with the tip shield. A cannula has a wall defining a lumen, a beveled distal end, an aperture in the wall of said cannula near the cannula distal end and a proximal end in the shape of a hook. The cannula passes through and is coaxially aligned with the catheter, adapter, tip shield and hub.

4. A method of forming a needle assembly comprising:
-
providing a needle cannula having a distal end and a proximal end; inserting the needle cannula into a needle hub; extending the proximal end of the needle cannula beyond the needle hub; crimping the proximal end of the needle cannula such that it is sealed and formed into a mechanical interlock at the proximal end; displacing the cannula distally such that the mechanical interlock is disposed within a glue well in the needle hub; inserting glue into the glue well; and curing the glue with UV light. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
