  • Publication number: 20120232492
    Abstract: A risk of injection liquid contamination due to contact of injection liquid in an injection-liquid filled area in a barrel with the surface in an injection-liquid unfilled area in the barrel by causing a plunger of a prefilled syringe to be inadvertently withdrawn by mishandling which may leads to medical malpractice, is eliminated by the invention. Withdrawal of a plunger 14 is limited by engagement of a barrel 12 in which a withdrawal-limiting member 48 is provided and a the plunger 14 in which a withdrawal-limiting member 54 is provided. As a result of this, contact of the injection liquid L prefilled to a liquid-filled area 32 in the barrel 12 with the surface of a liquid-unfilled area 34 in the barrel by withdrawal of the plunger 14 is prevented.
