This application is a divisional of U.S. patent application Ser. No. 12/792,290 filed Jun. 2, 2010, the disclosure of which is incorporated herein by reference in its entirety.
a tip protector for shielding the distal tip comprising an outer member and an inner member being axially received within the outer member, the outer member including a projection extending radially outward of the outer member and sized and configured to releasably engage with an interior of the catheter hub, the inner member having a pair of arms biased radially outward relative to a central axis and extending distally from a base to respective free ends, the needle cannula being received in the inner and outer members, the inner member, including the pair of arms, configured to be axially shiftable relative to the outer member between a first position wherein the distal tip extends distally of the tip protector and the free ends of the arms are spread apart such that the distal tip is not shielded, and a second position wherein the distal tip is within the inner and outer members and the free ends of the arms are brought into close proximity such that the distal tip is shielded, the inner member being entirely received within the outer member in both the first and second positions thereof.
2. The safety catheter of claim 1, the outer member further comprising at least one flexible tab, the projection being part of the at least one flexible tab.
3. The safety catheter of claim 2, wherein the at least one flexible tab is biased radially inward relative to the central axis.
4. The safety catheter of claim 2, wherein the interior of the catheter hub includes a retention groove for engaging the projection of the at least one flexible tab.
5. The safety catheter of claim 1, further comprising a locking mechanism configured to limit axial shifting of the inner member relative to the outer member when the inner member is in the second position.
7. The safety catheter of claim 1, wherein the inner member is axially shifted from the first position to the second position by movement of the needle cannula.
8. The safety catheter of claim 1, wherein the inner member includes a stop member for engaging a portion of the needle cannula to axially shift the inner member from the first position to the second position.
9. The safety catheter of claim 8, wherein the needle cannula includes a protuberance adapted to engage the stop member.
10. The safety catheter of claim 8, the inner member being plastic, the stop member being a metal washer.
11. The safety catheter of claim 1, the inner member including at least one rib associated with the free end of one of the arms adapted to block the path of the needle cannula when the inner member is in the second position.
12. The safety catheter of claim 1, the inner member including at least one projection for limiting movement of the needle cannula when the inner member is in the second position.
13. The safety catheter of claim 1, the distal tip being sharp.
14. The safety catheter of claim 1, the outer member being a thin-walled metal tubular member.
15. The safety catheter of claim 1, the arms of the inner member defining a tapered bore having a cross dimension smaller than a cross dimension of the needle cannula so as to block the path of the needle cannula when the inner member is in the second position.
16. The safety catheter of claim 1, wherein the catheter hub includes at least one wing.
17. The safety catheter of claim 1, wherein the catheter hub includes a side port.
18. The safety catheter of claim 1, the inner member configured to be axially slidable between the first position and an intermediate position, wherein in the intermediate position the distal tip is within the inner member and the free ends of the arms are brought into close proximity such that the distal tip is shielded.
19. The safety catheter of claim 18, the inner member being entirely received within the outer member in the intermediate position thereof.
20. The safety catheter of claim 18, the distal tip being within the outer member in the intermediate position.
