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. In using the apparatus for dye marking the nutritional product is flowed through the apparatus and a feeding tube to enter the gastrointestinal tract of a patient.
