Claims18
A spring clip for a catheter assembly, the spring clip comprising:
- first and second flexible arms, each configured to open and close the spring clip by a needle biasing the spring clip in an open position and releasing the spring clip to enclose a distal tip of the needle in a closed position;
- an opening for the needle to pass through;
- a distal wall having a lip provided on each of the first and second flexible arms, the needle biasing the lip in the open position, and the distal wall and the lip blocking the distal tip of the needle in the closed position, each of the distal walls includes a top wall portion and a bottom wall portion, the top wall portion is narrower in width than the bottom wall portion;
- and
- a rear wall connecting the first and second flexible arms;
- wherein
- the first flexible arm includes a cutout section facing opposite to the second flexible arm.
