Abstract

A safely disposable medical device includes a needle (115) having a needle front, a needle rear and an outer surface. The needle front includes a tip and the outer surface includes a portion contoured to provide one or more indented sections (130). The device further includes a housing (150) configured for enclosing at least a portion of the needle, an elongated member (110) for enclosing at least a portion of the needle, and a needle locking compartment (137) coupled to the housing. The releasable needle locking compartment includes a stopper pin (140) configured to rest on the needle and a drive element (135) positioned around the stopper pin on an inside of the needle locking compartment. The one or more indented sections facilitate holding of the stopper pin of the needle locking compartment thereby forming a locking mechanism with the one or more indented section of the needle when the needle is retracted from the elongated member.
