Zusammenfassung:The present disclosure relates to a vascular access device (1) comprising a vascular access tube (2), such as a cannula, having a tip region (3) terminating at a tip (4) for insertion into a blood vessel (V) of a patient, and at least one lumen (5) for injecting a drug and/or for introducing one or more catheters therethrough into the blood vessel (V). The device (1) further comprises a securing mechanism (10) operable to secure or secure the distal end region (3) of the vascular access tube (2) relative to the patient to inhibit or prevent exit of the tip (4) from the blood vessel (V) and/or to inhibit or prevent excessive insertion of the tip (4) into the blood vessel (V). A distal end (4) of a vascular access tube (2) has an opening (6) for communication between at least one lumen (5) of the access tube (2) and a blood vessel (V) of a patient, where the distal end (4) is inserted into the blood vessel (V), and a fixation mechanism (10) is ideally configured to position and fix the opening (6) of the distal
