ABSTRACT:
A needle device and method of use are disclosed, wherein the needle moves out of and into a protective housing, between two operative positions, one of which causes the housing to shield the needle. Each operative position includes releasable locking detents to temporarily hold the needle in one of those positions, the holding force of one being less than the other. A third position beyond the one that shields the needle in the housing is used to permanently lock the needle in the housing against accidental reuse. The needle device can be used with a blood collection container or a syringe drug delivery container, each one releasably mating with the device during use.
