An egg transfer system is provided. Such an egg transfer system includes a controller configured to receive a classification signal indicative of an egg classification status for each of a plurality of eggs carried by a flat. A transfer head assembly is in communication with the controller and is configured to remove a plurality of eggs from the flat. The eggs are grouped into at least a first and second subset based on the egg classification status. The controller is configured to direct the transfer head assembly to selectively release the first and second subsets separately based on the respective egg classification status of the eggs. An associated method is also provided.

A positioning device for presenting an avian bird is provided. Such a positioning device includes a frame and a plurality of positioning assemblies engaged with the frame. The positioning assemblies are configured to entirely support and restrain an avian bird in a flight-replicated position such that the avian bird is presented for various reasons, such as undergoing a vaccine delivery procedure, evaluation, or any other process. An associated method is also provided.

A remote delivery device is provided which has media portholes in a sidewall, a tail piece attached to a rear end and a cannula attached to a front end. The body contains a plunger assembly which defines an injectable liquid chamber and a marking media chamber. The plunger assembly includes a front barbell plunger, rear barbell plunger and a plunger shaft with an O-Ring seated between the front and rear of said plunger shaft. The body also contains a single internal charge positioned behind the plunger assembly. When the charge is activated, the plunger assembly is thrust forwardly and dispenses an injectable liquid from the injectable liquid chamber through the cannula. Simultaneously, the plunger assembly also dispenses a marking media from the marking media chamber through marking media portholes. The provision of a single internal charge allows for a reduction in the length and weight of the device. The single internal charge provides evidence of successful injection of the injectable liquid when the media is displaced from the marking media chamber.

Module for operational control of the guided advance/withdrawal device of the needle added to the smart substance injection device on board equipment for inoculating substances inside a fertile egg and smart method for injection inside a fertile egg, wherein the “inoculation of substances” inside a fertile egg, be this into the embryo, in the case of vaccines, and even into the amniotic fluid, in the case of a nutrient or nutritional vaccine complex, allows the injection needle (11) to be brought close at a controlled speed.

A device for administering a fluid, wherein, with the valve opened, fluid that is to be administered can be brought through the feed channel into the cylinder, and wherein a movement of the piston counter to the first direction towards the open dispensing end generates a positive pressure in the cylinder, such that, with the first valve opened, the fluid that is to be administered from the cylinder is dispensed via the open dispensing end, wherein, in order to seal the rear end of the cylinder, a first sealing element is arranged between the piston and the cylinder and a second sealing element is arranged spaced apart from the first sealing element along the first direction. The first sealing element can be a single-acting sealing element, and the second sealing element can be a single-acting or double-acting sealing element.

The present invention relates to a method and apparatus for delivering droplets of fluids onto an open tray containing poultry. According to the invention, the apparatus includes a stationary working surface, a single arm carrying a plurality of fluid dispensing nozzles, a drive unit comprising an electric motor for driving the translation of said single arm, said plurality of dispensing nozzles being connected to at least one fluid supply circuit comprising a fluid reservoir for supplying dispensing nozzles, the volume of fluid drawn from said reservoir being determined by a syringe, movement of the plunger of which is controlled by an electrical control element so that the plunger has a feed velocity V in the corresponding syringe. The apparatus also includes a controller for controlling the motor speed and the plunger feed velocity, said controller being configured to synchronize the acceleration/deceleration of the movable arm and the acceleration/deceleration of the plunger of said syringe or of at least one of said syringes.

The present invention relates to a method and apparatus for delivering droplets of fluids onto an open tray (15) containing poultry. According to the invention, the apparatus comprises a stationary working surface, a single arm (16) supporting a plurality of fluid dispensing nozzles, a drive unit for driving the translation of said arm (16), said plurality of dispensing nozzles being connected to at least one fluid supply circuit comprising a fluid reservoir and a pumping unit, a control unit configured to control the drive unit of the arm and to define at least one duration T of travel of the arm (16) above said working surface. The travel time T includes a period of gradual acceleration of said arm (16) outside an area of said working surface occupied by said tray and bringing said arm to a first end of said tray (15) along the first direction at a travel velocity V, a period of constant velocity V when the arm (16) moves above said tray (15), and a period of gradual deceleration of said arm (16) when the latter has passed a second end of the tray (15) along the first direction. The control unit is also configured to control each pumping unit and activate each pumping unit only when said arm is above said tray.

A vaccination system for delivering a vaccine substance to avian pullets is provided. Such a system includes a vaccine delivery assembly configured to perform a vaccine delivery procedure for delivering a vaccine substance to the avian pullets. A plurality of positioning devices is provided, with each positioning device receiving an avian pullet for presentation to the vaccine delivery assembly. Each positioning device is transported to individually mate with the vaccine delivery assembly to deliver the vaccine substance during the vaccine delivery procedure. Associated methods, devices, and assemblies are also provided.

An injection apparatus for injecting a medicament into a patient, the injection apparatus has a stationary head and a movable head that is movable with respect to the stationary head. A needle is attached to a needle holder that is held by the movable head and by the stationary head. When the movable head is urged rearwardly, a front edge of the needle moves forwardly with respect to a front face of the movable head.

Disclosed devices for injection of medicament to a subject can include a hand-held unit, at least one control unit, and one or more medicament chambers fluidly coupled to the control unit. The hand-held unit having a head portion and a body portion, the head portion comprising at least one needle and a movable head, the movable head being axially movable relative to the body portion between an extended position and a retracted position. The control unit being fluidly coupled to the hand-held unit and having a pump having a dosing chamber.
