This invention is a degassing cannula for veterinary use and refers to a stationary or fixable trocar used to release the gas that builds up in the stomach of farm animals and provide medication, water and food to the animal during or after the treatment.

A rigid hollow tubular adapter releasably attached at a longitudinal nozzle end to a flexible tube during equine nasogastric intubation comprising an annular sleeve having a stationary tubular member and a slidable tubular member. The slidable tubular member is delimited at its ends by the stationary tubular member and a detent member disposed between an equine reflux drainage hole and a longitudinal mouthpiece end. Operator's puffs of airflow through a mouthpiece urges the slidable member to slide toward the detent member closing the equine drainage hole to enable passage of medication into the equine stomach. Equine reflux urges the slidable tubular member to slide toward the stationary tubular member opening the reflux drainage hole to divert equine backflow downwardly through the equine backflow drainage hole preventing passage of equine reflux into the operator's mouth.

There is described a methane oxidation device for oxidation of methane from a digestive cavity associated with an animal, the device comprising a methane oxidation unit for oxidising methane; wherein the methane oxidation unit comprises an inlet portion in fluid communication with the external environment, the inlet portion further configured to be mounted to a hollow member in fluid communication with a digestive cavity associated with an animal, and further when the methane oxidation unit comprises an outlet portion in fluid communication with the external environment, so that methane from a digestive cavity associated with an animal is oxidised in the oxidisation unit prior to release into the external environment. There is further described an installation gun for installing a methane oxidation device.
