A gravitational fluid administration apparatus for large animals includes: a mechanism to allow a person of average strength to lift, lower, and suspend containers of blood, plasma, parenteral fluids, drugs, and supplemental salt solutions weighing as much as 25 kg without injuring the animal or human personnel; a hanger to hold the fluid containers; and a swivel mechanism to allow the suspended fluid containers to turn as the animal moves and to prevent kinking of the associated tubing. Further, there are "primary" and "secondary" tubing systems. The purpose of the primary tubing system is to convey fluids and drugs from fluid containers to the animal through a closed system. The primary tubing system is composed of connectors, securing straps, Y connectors, a drip chamber, shut-off clamps, side ports for the infusion of drugs or supplemental fluids, and sampling blood, and a coil of tubing to permit lengthening or shortening the effective length of the system as the animal moves away from or approaches the suspended fluid containers. The purpose of the secondary tubing system is to interconnect the fluid containers. The secondary tubing system consists of connectors, tubing and a shut-off clamp.

A specialized cannula and intraluminal cannula placement apparatus allow the insertion of an intraluminal cannula through a previously inserted standard I. V. catheter so that the intraluminal cannula extends beyond the end of a standard catheter. By using an intraluminal cannula of appropriate length, the intraluminal cannula may be used to bypass a flexure-caused obstruction in a vein during the administration of fluids in patients who are unable to cooperate with medical or veterinary procedures, most particularly with human infants, geriatric patients, and animals. Use of the specialized cannula and intraluminal cannula placement apparatus does not require removal of the previously placed I. V. catheter. The exterior diameter of the specialized cannula has a smaller diameter than the interior diameter of the previously placed standard I. V. catheter. A specially adapted seal seals the space between the inserted specialized cannula and a standard Luer hub of an I. V. catheter.

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.
