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.

[ We claim:] [1.] An apparatus for liquid enteral nutritional product feeding comprising:a formulation chamber having an inlet and an outlet, said inlet fluidly connected to a supply container containing a liquid enteral nutritional product having a viscosity of at least about 3 centipoises whereby said formulation chamber receives said liquid enteral nutritional product from said supply container;the formulation chamber further comprising at least one physiologically acceptable marker dye, the at least one marker dye being contained within at least one sustained release reservoir positioned within the formulation chamber so as to be in physical contact with said liquid enteral nutritional composition in said formulation chamber, the at least one marker dye being soluble in the liquid enteral nutritional product, said at least one sustained release reservoir containing marker dye being a means for providing and dispensing marker dye into said liquid enteral nutritional product when the sustained release reservoir is physically contacted thereby during the feeding thereof to a patient over a time period of at least about two hours; andfluid communication means capable of operatively connecting the outlet of the formulation chamber to a device that feeds the dye-marked liquid enteral nutritional product into the gastrointestinal tract of a patient.
