Abstract: A pneumatically operated egg injection machine includes a sealed frame structure with a pair of in line parallel tracks through an injection section and a transfer section in series. An injection assembly includes a plurality of injectors gripped in a support plate to simultaneously inject vaccine into the same injection region irrespective of egg height and orientation. Fluid delivery systems meter prescribed vaccine dosages to the injecting needles with reduced turbulence, friction, heat and residence time to increase the delivered titer to the injected eggs. A transfer assembly lifts the injected eggs by causing a reduced pressure around the injection hole while maintaining the injection hole at atmospheric pressure. The injection assembly is sprayed with a sanitizing solution at the same time that the injected eggs are moved from the injection section to the transfer section.

Abstract: An injection apparatus for injecting eggs of varying sizes and different orientations in an incubating tray that includes a substantially horizontal support plate with vertical openings therethrough, and vertical injectors resting in the openings and able to slide therein with respect to the plate such that the injectors can move vertically in the openings while remaining engaged with the support plate so as to maintain their vertical orientation throughout an injection sequence. For each opening, an expandable ring is positioned in the plate and pneumatically expanded to tighten around its respective injector after the injector has adjusted vertically in its respective opening to the height of an associated egg in order to maintain the injectors in their vertical orientation for injection of their associated eggs.

Abstract: A pneumatically operated egg injection machine includes a sealed frame structure with a pair of in line parallel tracks through an injection section and a transfer section in series. An injection assembly over one parallel track includes a plurality of injectors gripped in a support plate to simultaneously inject vaccine into the same injection region irrespective of egg height and orientation. Fluid delivery systems meter prescribed vaccine dosages to the injecting needles with reduced turbulence, friction, heat and residence time to increase the delivered titer to the injected eggs. A transfer assembly includes a plurality of transfer suction cups which lift the injected eggs by causing a reduced pressure in a ring around the injection hole while maintaining the injection hole at atmospheric pressure, thus avoiding negative pressure in the egg. Once the eggs are lifted, the plate and suction cups move horizontally across the machine over to the other parallel track to deposit the injected eggs.

Abstract: The present invention seeks to provide an improved needle design and needle assembly which is particularly adapted for live vaccines and the like. More specifically, the needle assembly includes a gap filler with an inner funnel which is specifically shaped and adapted to fill a turbulence gap naturally formed between a conventional needle retainer and syringe. By maintaining a laminar flow of the fluid, the turbulence and the destruction of live cells are reduced. Additionally, some of the needle designs include a funnel-shaped mouth which is utilized during the filling of the syringe to minimize physical damage to the cell wall or membrane of the live cells otherwise caused by the sharp edges at the tip of a standard injection needle. A breakaway needle assembly is also disclosed.
