RETRACTABLE INTRAVENOUSNEEDLE ASSEMBLY

摘要

A retractable intravenous needle assembly (10) wherein a cannula (12) is mounted on a hub (14) within an interior passage (32) formed in a housing (16) in which the cannula (12) and hub (14) are slidably mounted so as to have the cannula point (24) manually extend beyond the housing (16). Flexible wings (18) extending laterally from the housing (16) are manually folded upwardly to release a locking stop (34) formed in the interior passage (32) from engaging a locking lug (42) on the hub (14). The cannula point (24) is then manually retracted into the housing (16) until the locking lug (42) engages a locking recess (36) formed in the interior passage (32) to lock the hub (14) in the housing (16). The locking recess (36) is so located in the passage (32) that the housing (16) completely encloses the caccula point (24) when the locking lug (42) is locked in the locking recess (36), thus facilitating handling and disposal of the assembly without endangering hospital personnel. <IMAGE> <IMAGE>
