Abstract (en)

[origin: CA3239985A1] The invention relates to a veterinary syringe comprising a main part (2) which comprises a syringe cylinder (3) that has a front dispensing end (4) and a rear end (11) for receiving fluid to be dispensed, a piston rod (8) which has a front end section (9) with a piston (K) that is movably arranged in the syringe cylinder (3) along a movement direction (10), and a connection (26) for connecting to a fluid reservoir, wherein a fluidic connection is provided from the connection (26) to the syringe cylinder (3) through a supply channel (20) in the piston rod (8), and the piston rod (8) has a non-return valve (22) in the front end section (9) of the piston rod, said non-return valve blocking the fluidic connection and opening same only when the pressure in the supply channel (20) lies above the pressure in the syringe cylinder (3) by a specified value. The piston (K) is releasably connected to the front end section (9), and after the piston is released from the end section (9), the non-return valve can be accessed for maintenance purposes. An actuatable securing element (79, 85) is designed to prevent an accidental release of the piston (K) in that a release of the piston (K) from the front end section (9) is only possible after the securing element (79, 85) has been actuated.
