Veterinary syringe

Veterinary syringe, comprising:

• a main body, comprising a syringe cylinder, having a front dispensing end and a rear end, for receiving fluid to be dispensed;
• a plunger rod, including a front end portion with a plunger, which is arranged displaceably along a displacement direction in the syringe cylinder;
• and
• a connection for connecting to a fluid reservoir,
• wherein there is a fluid connection from the connection through a feed channel in the plunger rod as far as the syringe cylinder,
• wherein the plunger rod has a nonreturn valve which blocks the fluid connection and opens only when the pressure in the feed channel lies above the pressure in the syringe cylinder by a predetermined value,
• wherein the plunger is connected releasably to the front end portion and the nonreturn valve is accessible for maintenance purposes after the plunger is detached from the end portion,
• wherein an actuable safety mechanism is formed, which prevents an unintentional detaching of the plunger by detaching of the plunger from the front end portion being possible only after the safety mechanism is actuated.
