Abstract
A safety intravenous (IV) catheter assembly is disclosed which includes a safety device having a housing defining a cavity and distal and proximal openings, and a biasing member positioned within the cavity. The biasing member is movable from a first position to a second position to tilt the housing in relation to the needle when the needle tip is withdrawn through the distal opening of the housing to misalign the needle tip and the distal opening. A blocking arm is provided on the biasing member to prevent the biasing member from moving from the second position back to the first position.
