An IV catheter comprising: a catheter (20), which has a wall defining an internal cavity, a proximal end and a distal end； an adapter (22), which has a proximal end, a distal end and an internal cavity, such that said adapter is in fluid communication with the internal cavity of the catheter； a partition, located inside the adapter cavity, at the proximal end of the adapter； an extension tube, which extends laterally from the adapter and is in fluid communication with the adapter cavity； a tip protection (3), having a distal end, a proximal end and an internal cavity, such that said protection is located adjacent to the proximal end of the adapter and coaxially aligned with the adapter； a hub, having a proximal portion, a distal portion and an internal cavity, such that said hub is located adjacent to the proximal end of the tip protection and coaxially aligned with the tip protection； a cannula (111), which has a wall defining an internal cavity, a beveled distal end (12), an opening made in the wall of said cannula, near the distal end (12) of the cannula, and a proximal end ( 14), in the form of a hook (180), such that said cannula passes through, and is coaxially aligned with, the catheter, the adapter, the tip protection and the hub； characterized by a wall (17) for glue, which firmly grasps the hook (180) to hold the needle cannula firmly in place with respect to the needle hub while ensuring that the proximal end of the needle cannula It is sealed.Un catéter IV que comprende: un catéter (20), que tiene una pared que define una cavidad interna, un extremo proximal y un extremo distal； un adaptador (22), que tiene un extremo proximal, un extremo distal y una cavidad interna, de tal manera que dicho adaptador está en comunicación de fluido con la cavidad interna del catéter； un tabique, situado dentro de la cavidad del adaptador, en el extremo proximal del adaptador； un tubo de prolongación, que se extiende lateralmente desde el adaptador y está en comunicación
