Abstract
A needle guard assembly for a prefilled emergency syringe includes a cylindrical sidewall which extends coaxially with the syringe needle. The sidewall is joined to the syringe housing by spin welding or sonic welding an annular fusible portion that extends axially rearward from an annular flange on the base of the sidewall to contact the front wall of the housing. The sidewall is joined to the housing so that an annular clearance space for the hood is maintained between the hub and the sidewall guard.
