An injector, injection systems and methods for injecting a substance into an egg, where the injector includes a shaft, a sheath extending from the shaft in a longitudinal direction; a trocar positioned at least partly inside the sheath; and a needle at least partly inside the trocar. The injector can further include a locking mechanism configured to lock the trocar with the shaft in the longitudinal direction in a first position of the trocar relative to the sheath, the locking mechanism being further configured to unlock the trocar from the shaft in the longitudinal direction in a second position of the trocar relative to the sheath. The needle is fully inside the trocar in the first longitudinal position and at least partly extends from the trocar in the second longitudinal position.

System and method for injecting an egg

A device for reorientation of eggs deposited in the hollow open cells of a tray. The device is intended to reorientate at least one egg from said tray along a substantially vertical axis. The device includes at least one reorientation element capable of moving between a low position and a high position with respect to the cell containing the egg to be reorientated. The reorientation element includes a lower seat on which the upright rods are fixed, the upper ends of said rods being able to spread out with respect to each other on contact with the egg to be re-orientated, the upright rods being intended to interpose themselves between the cell and the egg, in the high position, so as to damp and guide a movement of the egg under the effect of its weight to a substantially vertical position.

Device for reorientation of an egg in a cellular tray

A distribution system for distributing dosed amounts of a treatment substance to a plurality of injectors of an egg injection device, and to an injection device equipped with such a distribution system. The distribution system comprises at least one syringe pump comprising an actuator for actuating the piston of a syringe, a discharge tube connected to the outlet orifice of the syringe, feed tubes connected in parallel to the discharge tube via a valve system, each feed tube being intended to be connected to an injector, and a controller capable of controlling the actuator and the valve system for distributing dosed amount of substance contained in the chamber through the feed tubes, to injectors.

Substance-distribution system for an egg injection device

An injection method for injecting a substance into eggs, and an injection head for implementing said method. The method generally includes piercing the shell and at least the shell membrane of an egg by moving a needle, and then injecting the treatment substance via said needle, said piercing step comprising a first movement of the needle to pierce the shell with a first penetration force and then a second movement of the needle to pierce at least the shell membrane with a second penetration force lower than the first penetration force.
