  • Publication number: 20100081999
    Abstract: A syringe for veterinary-medicine applications has a main body with a syringe cylinder whose discharge-side end is connected to a cannula and in which a piston connected to a piston rod is situated so it is displaceable. The syringe includes a protective module including protective cap and a securing element. The protective cap is mounted so it is displaceable on the main body, which receives the cannula in its first terminal position so that the front end thereof does not protrude from the protective cap. The securing element can be moved from a first securing position into a second securing position and then into a third securing position. The securing element releases a locking of the piston rod relative to displacements, so that the piston can be moved in the syringe cylinder in the direction toward the discharge-side end using the piston rod.
