Abstract
A safety needle device for protecting a user against a needle-stick injury. This needle device includes a needle housing having a distal housing opening. A needle is disposed within the needle housing and has a distal needle portion which extends away therefrom through the distal housing opening. An elongate sheath assembly surrounds the needle within the needle housing. A trigger member retains the sheath assembly within the needle housing against a force urging the sheath assembly towards the distal housing opening. The trigger member is sized and configured to release the sheath assembly from retention to allow the sheath assembly to transition towards and out of the distal housing opening via the force. This causes the sheath assembly to enclose the distal needle portion and protect the user against the needle stick injury.
