A vaccination device can be used to vaccinate day-old chicks. To vaccinate the day-old chicks safely while ensuring vaccination efficacy, the vaccination device can include a vaccination needle configured to extend from the vaccination device at a vaccination delivery location and an action plate. The action plate can be coupled to the vaccination device such that the action plate is positioned next to the vaccination delivery location. The action plate can include an action button, wherein the action button is configured to receive a day-old chick presented to the action plate in a predetermined loading position, receive a press of the action button, and in response to pressing the action button, cause the vaccination needle to extend from the vaccination device at the vaccination delivery location to deliver a subcutaneous injection to the day-old chick.

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.

A system for mass vaccinations including an electronic injector device having at least one needle for administering a measured amount of a vaccine; and an electronic fluid delivery device to deliver variable vaccine dosages to the injector device, and to deliver the measured amount of the vaccine.

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.

Embodiments of the invention provide multi-stage biodegradable drug delivery platforms and methods for the subcutaneous delivery of therapeutic agents (TA). Embodiments of the platform may be configured to subcutaneously deliver a first dose of a first TA which is absorbed into the body and/or blood stream (BBS) to produce a first therapeutic effect for a first selectable time period (STP), and subsequently after a second STP, deliver a second dose of a second TA which is absorbed into the BBS to produce a second therapeutic effect for a third STP. An embodiment of the platform may comprise a body having a tissue-penetrating end, a primary cavity having a first TA dose and a shell having a secondary cavity having a second TA dose. The first TA dose is released after the first STP and the second TA dose is released after the second STP by biodegradation of the shell.

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.

The disclosure relates to an extended-range spray applicator, and methods of making and use thereof, for dosing vaccines and/or probiotics to avian animals at a distance.

An injection device for administration of an injection to an animal can include a main body, which contains an injection instrument, a contact device, which has a contact area which is shaped in conformity with a body part of the animal to which the injection is to be administered. A support device which supports the contact device on the main body can be movable in a pressure application direction. A force measurement device including at least one force sensor can be designed to measure at last one force with which the contact device acts on the main body. A control device can activate the injection instrument if the force measured by the force measurement device lies in a specified range.

Poultry injection apparatus with rotating capture members and methods of using the same are described herein. Each injection apparatus may include one or more rotating capture members and an injection unit configured to move an injection needle between an injection position and a retracted position relative to the one or more capture members.
