摘要： A syringe includes a needle mounted in a frangible plug at the tip thereof and is equipped with a plunger having a stopper at one end thereof with the end of the plunger having an opening for capturing the end of the needle that projects into the barrel of the syringe to allow the plunger to capture the needle so that when the plunger is retracted the needle will be withdrawn into the barrel of the syringe; the end of the plunger is also equipped with a stopper which is mounted on a section that is connected to the plunger through frangible links whereby when the plunger is withdrawn a selected distance, the links will be severed to retain the plunger and captured needle within the barrel.
