A dome inhaler system is provided. The dome inhaler system includes a transparent dome with an opening designed to be placed over a pet's head to facilitate the pet's breathing of medicine dispensed within the dome. The system also includes an inhaler flange designed to mate an inhaler with the dome's opening to dispense a dose of medicine (preferably aerosolized) into the dome. Once the medicine is dispensed into the dome, the inhaler flange may be removed, and the dome may be placed over the head of a pet for the pet to freely breathe in the medicine. The system also allows for the metered or continuous introduction of therapeutic gasses and other concentrated atmospheres to the subject while the subject's head is within the dome. The dome may then be easily removed by lifting it off of the pet's head.

An anesthetization gas mask for a small animal includes a first mask part providing an inlet for an anesthetization gas and a second mask part for transmitting the anesthetization gas. The first and the second mask part define an anesthetization volume for receiving an animal’s mouth part. The second mask part transmitting the anesthetization gas is movably connected to the first mask part having the inlet for an anesthetization gas. The anesthetization gas mask is geometrically constructed such that a movement of the first mask part from a working position to a blocking position relative to the second mask part blocks the passage of anesthetization gas into the anesthetization volume. This anesthetization gas mask has a valve function integrated in the mask system itself, so that anesthesia gas is not spilled when not in use and with a fixed geometry so that the extraction is always present when handled.

A one-way respiratory valve includes a valve body. The valve body is hollow, opposite ends of the valve body are open, a partition plate is provided at one of the opposite ends, and an inhalation hole is formed at the other one of the opposite ends; an exhalation hole is formed on a side wall of the valve body, a second unidirectional guide member is provided at the exhalation hole of the valve body, and the second unidirectional guide member is unidirectionally accessible from an inside of the valve body to an outside of the valve body; and a middle part of the partition plate protrudes towards the inhalation hole to form a first protrusion, a first unidirectional guide member is provided on the first protrusion, and the first unidirectional guide member is unidirectionally accessible from the outside of the valve body to the inside of the valve body.

Provided is a method for treating animals, such as livestock, by exposing the animals to an airborne suspension of finely divided mineral salts. Treatment is effected upon inspiration of the mineral salts or skin contact with the mineral salts. The animals are accommodated in a treatment chamber with a substantially sealed limited confined volume and has a pressure difference airflow means, a dispensing means for the mineral salts and desiccant(s) in the walls and on the floor of the treatment chamber. The treatment chamber is a stationary installation or adapted as a trailer to treat animals during a journey or to transport the treatment chamber to the animals location, for example, a zoo or to apiaries.

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.
