Safety IV catheter with V-clip interlock and needle tip capture

A catheter assembly comprising:

• a catheter;
• a needle disposed in the catheter and having a distal tip;
• a catheter hub attached to the catheter and enclosing the needle;
• a needle shield configured to be connected to the catheter hub, the needle shield having a mounting protrusion including a projection extending from an inner surface of the needle shield, the mounting protrusion is integrated into the needle shield to form a unitary and monolithic structure;
• a clip including a first leg defining a first plane, a second leg defining a second plane forming a first space between the first plane and the second plane, and a periphery of a mounting cavity, the clip being disposed in the needle shield;
• wherein
• the clip has a first position that exposes the distal tip of the needle, the needle biases the clip in the first position, the clip includes a second position that shields the distal tip of the needle within the clip;
• and
• when the needle retracts, the clip transitions into the second position and while the clip substantially maintains an axial position, the needle unbiases the clip, causing the clip to deflect and shield the distal tip of the needle and causing the periphery of the mounting cavity to move into engagement with the mounting protrusion to secure the clip to the needle shield and avoid undesired movement or tampering of the clip, the periphery of the mounting cavity surrounds the mounting protrusion to engage the mounting
• protrusion, the periphery of the mounting cavity defining a second space outside of the first space;
• wherein
• the periphery of the mounting cavity does not engage the mounting protrusion in the first position whereby the periphery of the mounting cavity does not surround the mounting protrusion;
• wherein
• the needle compresses the second leg toward the first leg in the first position.
