  • Patent number: 5549550
    Abstract: A method for dye marking a liquid enteral nutritional product during delivery thereof from a supply container to a feeding tube delivering the nutritional product to the gastrointestinal tract of a patient includes the steps of: (1) providing apparatus such as a formulation chamber, e.g., a drip chamber, connectable to the supply container, with at least one sustained release reservoir containing a physiologically acceptable and dispersible marker dye positioned within the formulation chamber, and, liquid communication means connecting the formulation chamber to the feeding tube of a patient; (2) providing a supply container containing the nutritional product; (3) connecting the formulation chamber to the supply container and the liquid commmunication means to the feeding tube; and (4) flowing the dye-marked nutritional product through the apparatus and into the feeding tube.

  • Patent number: 5531681
    Abstract: An apparatus is disclosed for modifying a liquid enteral nutritional product during delivery thereof from a supply thereof, such as a hangable container, to a feeding tube delivering the liquid enteral nutritional product to the gastrointestinal tract of a patient. The apparatus has at least one formulation chamber, such as a drip chamber, with at least one controlled release dosage form unit in the form of a coated tablet, osmotically driven device, coated capsule, microencapsulated microspheres, agglomerated molecular sieving type material, or a quantity of fine hollow permeable fibers located therein. The controlled release dosage form unit or units contain at least one beneficial agent selected from nutrients, medicaments, probiotics, or diagnostic agents or mixtures thereof, to any of which a physiologically acceptable marker dye in controlled release dosage form and/or the same or different beneficial agent not in controlled release dosage form may be added.

  • Patent number: 5531734
    Abstract: A method is disclosed for modifying a liquid enteral nutritional product during delivery thereof from a supply container to a feeding tube delivering the nutritional product to the gastrointestinal tract of a patient. During enteral tube feeding the nutritional product passes through a formulation chamber, e.g., a drip chamber, having located therein at least one controlled release dosage form unit containing at least one beneficial agent. The beneficial agent may be selected from nutrients, medicaments, probiotics, or diagnostic agents or mixtures thereof, and any such together with a physiologically acceptable marker dye in controlled release dosage form and/or the same or different additional beneficial agent not in controlled release dosage form. Controlled release dosage forms may be of a conventional sustained release type or an osmotically driven delivery device.

  • Patent number: 5531682
    Abstract: An apparatus is useful for dye marking a liquid enteral nutritional product during delivery thereof from a supply container to a feeding tube delivering the nutritional product to the gastrointestinal tract of a patient. A formulation chamber, such as a drip chamber, is connectable to the supply container. At least one sustained release reservoir containing a physiologically acceptable marker dye is positioned within the formulation chamber, or if not, is included as part of a kit. The sustained release reservoir may be in the form of a coated tablet, osmotically driven device, coated capsule, microencapsulated microspheres, agglomerated molecular sieving material, or chopped hollow fibers having permeable walls. A liquid communication means connects the formulation chamber to the feeding tube of a patient. The marker dye may be a colorant dye or a fluorescing dye or a mixture thereof.
