Abstract
An animal inhalation apparatus includes a mask which is directly fastened to a vaporizer. The baglike mask has a portion of its surface disposed in the mouth of a horse and is secured by a tightening belt so that the horse is prevented from opening its mouth and is forced to breath through its nostrils, which lie inside of the bag. The vaporizer operates in the rhythm of the breathing process. The horse is not connected to the vaporizer through a cumbersome hose, and only the respiratory organs are in contact with the inhalation medium.
