Abstract
A tip protector for a safety catheter includes an outer member releasably engaged with the interior cavity of the catheter hub. The outer member includes a generally fixed radially outwardly projecting portion to provide a holding force, and an inner member axially shiftably received within the outer member. A needle cannula received in the inner and outer members is operable to axially shift the inner member between a distal position wherein the distal tip extends distally of the tip protector, and a proximal position wherein the distal tip is within the outer member. The holding force of the outer member to the interior wall of the catheter hub remains substantially constant irrespective of the position of the inner member between the distal and proximal positions.
