Device and methods for delivering fluids to animals

A device for administering a fluid to an animal, said animal having an oral cavity, esophagus and stomach, said fluid administered through a tube and said tube having at least one tube wall having an interior tube surface defining a tube passage and at least one exterior tube surface, said at least one tube wall having a tube length to distend from the oral cavity into the esophagus, said exterior tube surface having a diameter not greater than the diameter of the animal's esophagus, said at least one tube wall defining a first tube end and a second tube end, said first tube end for placing in said oral cavity and into said esophagus and said second tube end for extending out of said oral cavity for administering fluids;

• said device comprising:
• a sheath having a first sheath section and a second sheath section, said sheath sized and shaped to have said first sheath section towards a first sheath end and said second sheath section toward a second sheath end, said sheath having a length and width having a expanded width configuration and a folded width configuration, said length greater than the length of said tube such that upon being extended said sheath forms a cylinder, said expanded width configuration allowing said sheath to be pulled over said exterior surface of said tube, and said folded width configuration comprising one or more folds along said length to allow the sheath to pass through the tube passage,
• said sheath having at least one first sheath wall, said at least one sheath wall being flexible and having at least one first sheath surface and at least one second sheath surface,
• said sheath having a first position in which said first sheath surface of said first sheath section is positioned facing itself and said second sheath surface is facing away from itself with the width in said folded width configuration and a second position in which said second sheath surface of said first sheath section faces itself and said first sheath surface faces away from itself with the width in said expanded width configuration, said sheath moving from said first position to said second position upon folding said first sheath section at said first sheath end over said tube to invert said first sheath section of said sheath and to draw said second sheath section of said sheath into the tube passageway, forming a fluid conduit for dispensing fluids with said first sheath section of said sheath shielding said exterior surface of tube from contact with the oral cavity or esophagus of an animal, said sheath prior to assuming said second position maintained in with said first position.
