Abstract
It is a primary object of the present invention to provide an automated system based on an integral fluid bag for administering a variety of intravenous drug regimens and reducing the vagaries of existing manual systems. The fluid has multiple chambers configured to implement a prescribed intravenous medical therapy. Each chamber'"'"'s geometry (size, shape), sequence and position, alone and in combination with the other chambers, matches the prescribed intravenous therapy or drug regimen. The bag'"'"'s configuration assures that the intravenous therapy is administered in accordance with the prescribed drug regimen, thus automating the previous manual method. A choice of fluid bag configurations may be stocked so that a prescription for well known and widely accepted drug regimens may be filled by merely selecting a bag with the appropriate chamber configuration and filling it with the prescribed medications.

5. A fluid cartridge having fluid chambers for delivering a sequence of fluids to a patient comprising:
-
a cartridge having at least two separate fluid chambers, each chamber being connected ultimately to a common tube via a fluid exit path, said chambers being arranged in line for sequential automatic delivery of fluids, at least one fluid chamber having a back flow prevention device disposed between said fluid chamber and said common tube to prevent back flow into said fluid chamber, at least one of said chambers having a resealable filling port, and the exit path of at least one chamber having a length and radius for controlling flow of fluid from said fluid chamber when a pressure is generated within said fluid chamber. - View Dependent Claims (6, 7, 8)

30. A cartridge for use in the automatic administration of an intravenous therapy comprising a plurality of separate chambers, each chamber being filled with a respective fluid associated with the intravenous therapy and each having a predetermined geometry for defining the rate at which the intravenous therapy is administered.
-
31. A cartridge for use in the automatic administration of an intravenous therapy comprising a plurality of separate chambers that are each configured to be filled with a respective fluid associated with the intravenous therapy and that each includes an exit port having a length and an effective radius that results in fluid flowing from the respective chamber through the exit port at a predetermined rate upon the application of a predetermined pressure on the respective chamber.
-
32. Apparatus for automatic administration of an intravenous therapy, comprising:
-
cartridge means for supplying liquid medications in a predetermined sequence, the cartridge means including a plurality of chamber means, each chamber means for holding a predetermined quantity of a predetermined medication associated with the intravenous therapy; automatic pressurization means for causing the liquid medications to flow from the chamber means in accordance with the intravenous therapy.
-
- 33. A cartridge for use in the automatic administration of an intravenous therapy comprising a laminate of a first material and a second material which are bonded together at predetermined areas to form at least three separate chambers that are each configured to be filled with a respective fluid for infusion into a patient upon the application of pressure on the respective chamber.
