  • Patent number: 6726655
    Abstract: The present invention comprises a medication delivery system for administering an infusion therapy using a medication delivery pump and related fluid container. Medications in a flexible bag of the container are expelled from the bag by the pump into an administration set and delivered to an infusion site. The administration set limits the rate at which a spring compresses the bag. The system provides improved infusion therapy administration which is particularly advantageous for reducing errors, infections and other complications associated with manual infusion techniques.

  • Patent number: 6669668
    Abstract: The present invention comprises a medication delivery pump that is configured to administer an infusion therapy using a medication delivery container. Medications in a flexible bag are expelled from the bag and delivered to an infusion site. A fluid delivery pump of the invention may have a constant force spring and a mechanical timer. The constant force spring is configured to compress a flexible fluid container. The mechanical timer assembly is coupled to the constant force spring and limits the maximum rate at which the spring compresses the fluid container. The pump may include first and second doors for charging the spring. Opening the first pump door partially charges the constant force spring and opening the second pump door fully charges the constant force spring. The pump provides improved administration of infusion therapy which is particularly advantageous for reducing errors, infections and other complications associated with manual infusion techniques.

  • Publication number: 20030130645
    Abstract: The present invention relates to delivery containers designed to deliver fluids for infusion to patients in a predetermined sequence, and methods for their construction and use. The containers described herein integrally comprise a plurality of non-fluidly connected chambers. The containers may be configured to deliver a volume of each medication of an infusion therapy in a predetermined sequence, duration, and/or interval from these chambers; alternatively, a container may be part of a larger device that provides the necessary hardware to perform such predetermined delivery. The container provides improved infusion therapy administration by reducing opportunities for error, infection, adverse drug interactions, or other complications.

  • Publication number: 20030040708
    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.
