Abstract
A syringe package includes a hollow barrel and a slidable plunger inside the barrel extending out of its proximal end. A needle cannula extends from a distal end of the barrel. A shield covers the cannula and is connected to the barrel to provide a seal thereto. The shield has a frangible portion adapted to be ruptured so that a first portion of the shield is removable and a second portion remains connected to the barrel as evidence of a broken seal. A cap covers the proximal end of the plunger and is connected to the barrel to provide a seal. The cap has a frangible portion adapted to be ruptured so that a first portion of the cap is removable and a second portion is adapted to remain connected to the barrel as evidence of a broken seal at this end of the syringe.
