The present invention relates to a dispensing apparatus for the controlled dispensing of a high viscosity feed supplement hydrogel, which has a fluid container (A), a diaphragm pump (1), a fluid box (B) in which dispensing nozzles (6) are arranged.

The invention is characterized in that within the fluid box (B) it has a pressure regulator (2), one or more pneumatic dispensing valves (3) associated with the pressure regulator (2), and a fluid distributor (5) connected to the lower outlet openings of each pneumatic dispensing valve (3), wherein to each fluid distributor (5) one or more dispensing nozzle(s) (6) are arranged orderly in several rows, a solenoid valve (4) is connected to an upper outlet connector of the pneumatic dispensing valve (3), an outlet of an air pressure regulator (8) is connected to one of the inlets of the solenoid valve (4) and an outlet of a control box (C) is electronically connected to another inlet of the solenoid valve (4), which control box (C) can also be operated via WIFI by a remote control (9), another outlet of the air pressure regulator (8) is connected to an inlet of the diaphragm pump (1), an optical sensor (7) is arranged in the fluid box (B) for optimal control of the dispensing nozzles (6), an outlet of the optical sensor (7) is connected to one of the inlets of the control box (C).

A device for administering a fluid can include a cylinder, a piston connected to a piston rod, and a tensioning device connected to the piston rod. The tensioning device includes a ramp which is rotatable via a motor, a ramp track, and a roller. A dose setting means can be provided which comprises a spacer and a movement unit. The spacer moves from a neutral position into an active position such that the driver is stopped by the spacer so the piston stroke during the movement of the piston to the open dispensing end is shorter in comparison to the case in which the spacer is in its neutral position. The spacer has a through bore in which a spindle with a spindle thread is guided. A pin protrudes into the spindle thread. The spindle thread leads at at least one of its two ends into an annular groove.

A system for mass vaccination includes a plurality of portable electronic injectors, a mobile process manager and a database. Each portable electronic injector includes at least one needle to administer a measured amount of at least one vaccine to a body skin/tissue and an indicator system to provide an indication when either an injection error occurs or when a vaccination indication is required. The mobile process manager is in wireless communication with the plurality of injection devices and controls a mass vaccination. The process manager transmits task data to all injection devices in parallel via WI-FI, receives the vaccination indications from each injector in real time, also receives injection errors and vaccination process data, alerts a vaccination process overseer generally in real-time of the errors and transmits the injection data from each injector via cellular and/or internet transmission to the database.

A double barreled injector assembly for performing multiple sequential vaccinations includes a pair of barrels, each of which is engaged by a first terminus thereof to a bar and extends from a lower face thereof. A respective agent can be positioned in each barrel. Each barrel has an orifice positioned in a second terminus thereof. A pair of actuators is engaged to an upper face of the bar. Each actuator is operationally engaged to a respective barrel and can be actuated by action of a hand of a user to dispense an associated agent through the orifice of the respective barrel into an animal. The injector assembly allows the user to perform multiple sequential vaccinations with two different vaccines and will be useful in vaccination of herds or flocks of livestock, such as poultry, cattle, and the like.

A device for dispensing a fluid drop-by-drop can include a fluid connector to supply the fluid to be dispensed, a pump which is fluidically connected to the fluid connector, an outlet nozzle which is fluidically connected to the pump, an actuating element, and a control unit. When the actuating element is actuated, the control unit activates the pump which pumps the supplied fluid to the outlet nozzle for dispensing drop-by-drop. The outlet nozzle has an outlet opening and a fluid channel which extends as far as the outlet opening and which, in the direction of the fluid from the pump as far as the outlet opening, has a first channel portion with a first cross-sectional surface and a second channel portion with a second cross-sectional surface adjoining the first channel portion. The second cross-sectional surface can be smaller than the first cross-sectional surface.

A system for vaccinating swine according to one embodiment includes a housing having an open first end and an open opposite second end. The housing has a pair of side walls that are angled and non-parallel to one another such that at the second end only a single piglet can exit at one time. The system also includes a vaccination station for individually vaccinating piglets. The vaccination station is located between the pair of side walls in a region thereof that is sized to only permit one piglet to stand between the side walls. The vaccination station includes at least one sensor that detects the presence of the one piglet within the vaccination station and at least one spray nozzle positioned within the vaccination station such that a vaccine dose discharged therefrom is directed upwardly into facial areas of the piglet effectively.

A device for administering a fluid can include a cylinder, a piston connected to a piston rod, and a tensioning device connected to the piston rod. The tensioning device includes a ramp which is rotatable via a motor, a ramp track, and a roller which is in contact with the ramp track and which is mounted rotatably in a driver. The driver can be connected to the piston rod via a joint. In a tensioning procedure, the ramp track is rotated such that the roller runs on the region of inclination as far as the second plateau and the piston is thereby moved to its rear end position. In a dispensing procedure, the ramp track is rotated until the roller runs over a transfer region and, on account of the tensioning, is accelerated toward the first plateau and, as a result, the piston is moved toward the an dispensing end.

The invention relates to spray applicator devices and methods of use for vaccinating, or administering probiotics to, avian animals.

Described herein is a drug product delivery device and method of delivering a drug on a swab. The drug product delivery device may include an applicator platform housed within a rigid housing. The applicator platform may be in the form of a plunger. The foil drug reservoir cap creates a fluid storage chamber disposed between the foil drug reservoir cap and the plunger. A series of fluidic channels carry fluid from the fluid storage chamber to an applicator. A frangible seal is attached to the plunger between the fluid storage chamber and the applicator. The frangible seal blocks a fluid from moving from the fluid storage chamber into the series of fluidic channels. Actuation of the plunger causes the frangible seal to be ruptured, which causes the fluid to exit the fluid storage chamber and enter into the fluidic channels. The fluidic channels carry the fluid to the applicator.

The present disclosure describes a self-sprayer device for self-administering an animal product to an animal and providing environmental enrichment to the animal.
