  • Apparatus for the administration of fluids to a small animal
    Patent number: 5163923
    Abstract: Apparatus for the administration of fluids to an animal which permits movement of the animal within an enclosure without the development of kinks and twists in fluid flow tubing in the apparatus which would otherwise cut off fluid flow to the animal. A resiliently flexible coiled tube is mounted on a swivel unit to which fluid is supplied and through which fluid passes. The coiled tube uncoils and recoils as the animal moves. In addition, rotational movements by the animal are accommodated by the swivel unit.
