1. A method for the administration of a beneficial drug to an animal, which method comprises:
- (a) admitting into the animal a delivery member in fluid communication with an intravenous delivery system, the system comprising;
(1) a reservoir of a pharmaceutically acceptable fluid;
(2) a drip chamber in fluid communication with the reservoir;
(3) a container in fluid communication with the drip chamber and with the delivery member, the container comprising;
(i) a wall that surrounds a lumen, said wall formed of a flexible material that moves from an expanded position to a collapsed position as drug formulation leaves the container;
(ii) a passageway through the container, said passageway formed of a material that permits a fluid to enter the container and permits a fluid drug formulation to leave the container;
(iii) a beneficial drug in the container that forms a fluid drug formulation with fluid that enters the container; and
,(b) administering the drug to the animal by letting fluid enter the container to form the fluid drug formulation that, as the container collapses, leaves the container for administering to the animal.

2. A parenteral delivery system for administering a beneficial drug to a recipient, the delivery system comprising;
-
(a) a reservoir of a pharmaceutically acceptable fluid; (b) a drip chamber in fluid communication with the reservoir; and
,(c) a container in fluid communication with the drip chamber, the container comprising; (1) a wall that surrounds a lumen, said wall formed of a flexible, fluid and agent impervious material capable of changing from a expanded to a collapsed position over time; (2) a passageway in the wall and extended through the lumen for letting fluid enter the lumen, and for letting a fluid drug formulation leave the lumen, the passageway formed of a material that permits the passage of fluid and fluid drug formulation over time; and
,(3) a beneficial drug in the lumen that forms a fluid drug formulation with fluid that enters the container. - View Dependent Claims (3, 4, 5, 6)

7. A method for administering a beneficial agent to an animal, which method comprises:
-
(a) admitting into the animal a delivery member in fluid communication with an intravenous delivery system, the system comprising; (1) a reservoir of a pharmaceutically acceptable fluid; (2) a drip chamber in direct fluid communication with the reservoir and with the delivery member; and
,(3) a fluid path that circumvents the direct path, said fluid path comprising; (i) a container in fluid communication with the reservoir and in fluid communication with the drip chamber, the container comprising; (a) a wall that surrounds an internal lumen, said wall formed of a flexible material that collapses as a drug formulation leaves the container; (b) a passageway through the lumen, said passageway form of a material that permits a fluid to enter the lumen and permits a fluid drug formulation to leave the lumen; (c) a beneficial drug in the lumen that forms a fluid drug formulation with fluid that enters the lumen; and
,(b) administering the drug to the animal by letting fluid enter the container to form the fluid drug formulation, that as the container collapses, leaves the container and passes through the drip chamber for administering to the animal.

8. A parenteral delivery system for administering a beneficial drug to a recipient, the delivery system comprising:
-
(a) a reservoir of a pharmaceutically acceptable fluid; (b) a drip chamber in direct fluid communication with the reservoir; and
,(c) a fluid path that circumvents the direct path, said circumventing fluid path comprising; (i) a container in fluid communication with the reservoir and in fluid communication with the drip chamber;
said container comprising;(a) a wall that surrounds an internal lumen, said wall formed of a flexible material that collapses as a drug formulation leaves the container; (b) a passageway through the lumen for letting fluid enter the lumen and for letting fluid drug formulation leave the lumen, said passageway formed of a material that permits the passage of fluid into the lumen and permits the passage of drug formulation from the lumen; and
,(c) a beneficial drug in the lumen that forms a fluid drug formulation with fluid that enter the lumen. - View Dependent Claims (9, 10, 11, 12)
