An unloader for a poultry inspection and vaccination transporter. The unloader has a horizontally disposed unloader bar that is operable between a carry position, in which the poultry is carried on a hanger of the transporter, and an unload position, in which vertical displacement of the unloader bar between the poultry and the hanger urges the poultry from its suspended position in the hanger to release the poultry from the hanger. The unloader bar may be operated by cooperative engagement of a vertically disposed shaft to which the unloader bar is connected, with an ramp assembly disposed in a traversal path of the transporter.

Injection systems and methods of using the same are described herein. Each injection system may include one, two, or more needles, with each needle being configured to move needle between an injection position and a retracted position to deliver an inoculant. The injection needles may rotate about a carriage axis that extends through the injection axis along which each needle moves when moving between their injection and retracted positions. The injection needles in systems that include two or more injection needles may be advanced from the retracted position to the injection position at the same or different times.

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.

Pellet delivery systems capable of reliably and precisely delivering pellets over a large area are disclosed. In some examples, the system can deliver one or more pellets in one delivery cycle using a slide chamber. In other examples, the system can deliver one or more pellets per delivery cycle using a rotating disk comprising one or more holes. In any of these examples, the system can eject the pellets using a projector and/or gravity. The pellet delivery system can, in various examples, be utilized in conjunction with a carrier such as an airborne, terrestrial or aquatic vehicle, or in other examples with a human or animal carrier. Examples of the disclosure are also directed to precise pellet delivery based on the location of the pellet deliver system, pellet delivery tracking, adjusting pellet delivery, and determining paths for efficient pellet delivery.

An apparatus for injecting a liquid into live animals, comprising a cradle plate (18) having a cradle (24) for accommodating at least a part of an animal, sensors (20-1, 20-2, 20-3) for detecting a force acting upon the cradle plate, an injection mechanism (16) for injecting liquid into the animal, and a control unit (38) for triggering the injection mechanism (16) in response to signals received from the sensors, wherein at least three sensors (20-1-, 20-2, 20-3) are arranged for measuring forces with which the cradle plate (18) is pressed against a base (12) in at least three non-aligned positions, and the control unit (38) is adapted to trigger the injection mechanism (16) when the forces measured by the sensors are distributed according to a predetermined pattern.

The present invention relates to a device for injecting fluid into a bird, the device having a main body (11), which comprises an injection assembly comprising an injection needle and at least one syringe, the needle being movable between a retracted position and an injecting position located in an injection zone positioned outside the main body (11). According to the invention, said device comprises:a guide element (12) positioned on an exterior surface of the main body (11), the guide element (12) comprising a base (13) and side edges (14) extending from said base, at least the upper part of the back of the bird to be vaccinated being intended to rest against said base (13) and to be moved, head first, along a guide axis (15) defined by the guide element (12), to the injecting position,the guide element (12) being additionally configured to keep at least the neck of the bird aligned or substantially aligned along said guide axis (15) in the injection zonethe injection needle being arranged such that when it is moved between the retracted and injecting positions, it moves along an axis of movement parallel to the exterior surface of the base, or at an angle relative to said exterior surface, said axis of movement extending, away from the main body, beyond an exclusion zone surrounding the guide axis (15).

An injection apparatus for sequentially injecting a patient with at least two medicaments may include a hand-held unit comprising a grip for being held by an operator, a single needle, a base unit coupled to the hand-held unit via at least one connecting tube, at least two containers for holding medicaments removably coupled to the base unit, and at least one pump. The at least one connecting tube can be flexible enough to enable easy maneuvering of the hand-held unit and rigid enough to prevent widening of the tube due to inner pressure when medicaments pass from the containers to the hand-held unit. The injection apparatus can be used to administer the at least two medicaments sequentially at different injection points.

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.

A medicament injection device including a needle, a first stage that controls positioning of the needle at a depth into an animal when the device is pressed against the animal, and a second stage that injects the medicament through the needle into the animal after the needle is positioned at the depth and the device is further pressed against the animal. The device preferably includes a mechanism that permits the second stage to inject the medicament only after the needle is positioned at the depth. The depth of the needle preferably is adjustable, as is the amount of the medicament injected. In preferred aspects, these two features are independently adjustable. One or more springs, pneumatics elements, or other elements may automatically reset the first stage, the second stage, or both after the device is withdrawn from the animal. Also, associated methods.
