Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
255 words
In an inhalation apparatus for an animal which includes a mask having means for facilitating inhalation and exhalation by an animal wearing said mask, and means for supplying to said mask a gaseous inhalation medium, the improvement comprising wherein said mask includes a bag which is open at an upper end thereof and has a cavity which communicates with said open upper end and is adapted to receive the nose of the animal, said open upper end of said bag terminating in a generally semi-cylindrical wall part and a flattened wall part extending across the concave side of said semi-cylindrical wall part, said semi-cylindrical wall part and said flattened wall part of said bag each terminating in an upper edge, said upper edges defining said open upper end of said bag, and wherein said mask includes an adjustable belt which extends around said bag, said belt having a first portion which is adjacent said semi-cylindrical wall part of said bag and a second portion which is spaced outwardly from said flattened wall part, said belt being spaced below said upper edge of said flattened wall part, whereby said flattened wall part can be placed in the mouth of the animal so that said bag receives the nose of the animal and the space between said second portion of said belt and said flattened wall part receives the lower jaw of the animal, and said adjustable belt can then be tightened until the animal is prevented from opening its mouth and must breathe through its nostrils.
Claim 2
Dependent Claim
255 words
In an inhalation apparatus for an animal which includes a mask having means for facilitating inhalation and exhalation by an animal wearing said mask, and means for supplying to said mask a gaseous inhalation medium, the improvement comprising wherein said mask includes a bag which is open at an upper end thereof and has a cavity which communicates with said open upper end and is adapted to receive the nose of the animal, said open upper end of said bag terminating in a generally semi-cylindrical wall part and a flattened wall part extending across the concave side of said semi-cylindrical wall part, said semi-cylindrical wall part and said flattened wall part of said bag each terminating in an upper edge, said upper edges defining said open upper end of said bag, and wherein said mask includes an adjustable belt which extends around said bag, said belt having a first portion which is adjacent said semi-cylindrical wall part of said bag and a second portion which is spaced outwardly from said flattened wall part, said belt being spaced below said upper edge of said flattened wall part, whereby said flattened wall part can be placed in the mouth of the animal so that said bag receives the nose of the animal and the space between said second portion of said belt and said flattened wall part receives the lower jaw of the animal, and said adjustable belt can then be tightened until the animal is prevented from opening its mouth and must breathe through its nostrils.
Claim 3
Dependent Claim
136 words
The inhalation apparatus according to claim 1, wherein said semi-cylindrical wall part and said flattened wall part each have a lower edge opposite said upper edge thereof; wherein said bag defines a bottom wall part which extends between said lower edges of said semi-cylindrical and fattened wall parts, wherein said means for supplying to said mask a gaseous inhalation medium includes vaporizer means for producing a gaseous inhalation medium supported on the exterior surface of said bottom wall part of said bag, and wherein said bag is made of a flexible material which is generally impermeable to air except for a portion of said bottom wall part in the region of said vaporizer means which is gas permeable to permit the gaseous inhalation medium to flow from said vaporizer means to the inside of said bag.
Claim 4
Dependent Claim
15 words
The inhalation apparatus according to claim 2, wherein said vaporizer means is an ultrasound inhalator.
Claim 5
Dependent Claim
53 words
The inhalation apparatus according to claim 1, including an elongate holding belt which has two ends, each said end of said holding belt being connected to said upper edge of said semi-cylindrical wall part of said bag, said holding belt being adapted for placement over the back of the head of the animal.
Claim 6
Dependent Claim
53 words
The inhalation apparatus according to claim 1, wherein a resilient sealing cushion is supported on the interior surface of said semi-cylindrical wall part of said bag and extends along the entire length of said semi-cylindrical wall part adjacent said upper edge thereof, whereby said cushion can sealingly engage the nose of the animal.
Claim 7
Dependent Claim
25 words
The inhalation apparatus according to claim 1, wherein said bag has reinforcing rib means for preventing the collapse of said bag during an underpressure therein.
Claim 8
Dependent Claim
35 words
The inhalation apparatus according to claim 1, wherein said means for facilitating inhalation and exhalation includes said bag having inlet and outlet valve means for allowing fluid flow into and out of said bag, respectively.
Claim 9
Dependent Claim
108 words
The inhalation apparatus according to claim 7, wherein said means for supplying to said mask a gaseous inhalation medium includes said mask having vaporizer means for producing a gaseous inhalation medium supported on an exterior surface of said bag in the region of said inlet valve means, said vaporizer means including housing means defining a chamber in fluid communication with said inlet valve means and which can communicate with the interior of said bag through said inlet valve means, a vaporizer in said chamber, and means responsive to said inlet valve means for respectively actuating and deactuating said vaporizer as said inlet valve means opens and closes, respectively.
Claim 10
Dependent Claim
46 words
The inhalation apparatus according to claim 1, wherein said upper edge of said flattened wall part of said bag terminates below said upper edge of said semi-cylindrical part thereof, and wherein said flattened wall part of said bag has an indentation in said upper edge thereof.
