ABSTRACT:
A retractable intravenous needle assembly wherein a cannula is mounted on a hub within an interior passage formed in a housing in which the cannula and hub are slidably mounted so as to have the cannula point manually extend beyond the housing. Flexible wings extending laterally from the housing are manually folded upwardly to release a locking stop formed in the interior passage from engaging a locking lug on the hub. The cannula point is then manually retracted into the housing until the locking lug engages a locking recess formed in the interior passage to lock the hub in the housing. The locking recess is so located in the passage that the housing completely encloses the cannula point when the locking lug is locked in the locking recess, thus facilitating handling and disposal of the used assembly without endangering hospital personnel.
