摘要:
A method of assembling telescopically a flexible tubular segment with a length of tubing involves the use of an assembly apparatus which controllably stretches a tubular segment. The free end of a portion of an end of a length of tubing is inserted through the stretched tubular segment a preselected distance. The stretched tubular segment is allowed to relax around the inserted portion of an end of the length of tubing, thus assembling the tubular segment with the end portion of a length of tubing. The tubular segment and portion of an end of a length of tubing that have been assembled together are then ejected simultaneously from the assembly apparatus.

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. The sustained release reservoir may be a conventional slow release coated tablet, microspheres, or capsule type or an osmotically driven device. The marker dye may be a colorant dye or a fluorescing dye or a mixture thereof. If quick coloration is desired, the sustained release reservoir may be coated with a soluble layer of the marker dye or marker dye not in a sustained release reservoir may be placed in the formulation chamber along with a sustained release reservoir containing dye.

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. A liquid nutritional product flows through the formulation chamber during enteral tube feeding of a patient.
摘要:
A replacement gastrostomy tube device is provided comprising a catheter shaft having an outer surface wall, with the shaft enclosing a feeding lumen of substantially circular cross-section and a fluid flow channel. A port housing is located at the proximal end of the shaft with the port housing having a main food inlet port, a Y-port and a fluid inlet port. Near the distal end of the tube are an expandable component member and a food outlet port, which port is preferably located at the distal end. The feeding lumen is of a greater diameter than that of the fluid flow channel. The outer surface wall is of a non-circular cross-section. The feeding lumen is of a circular cross-section which permits the passage therethrough of a jejunal tube. The main food inlet port is of a greater diameter than that associated with the Y-port. The method for using this device permits jejunal feeding through a replacement gastrostomy tube without retraumatizing the patient.

摘要:
An apparatus for modifying a liquid enteral nutritional product. The apparatus includes a chamber having an inlet and an outlet. The inlet of the chamber is constructed to be fluidly connected to a supply container containing a liquid enteral nutritional. The chamber defines an interior space. The apparatus further includes a retainer disposed in the interior space defined by the chamber. The retainer is constructed to receive one or more dosage form units of beneficial agent therein. The apparatus further includes at least one dosage form unit of beneficial agent retained by the retainer.
摘要:
An apparatus is disclosed which has utility for assembling a flexible tubular segment telescopically upon an end portion of a length of tubing when the tubing has an outer diameter which is substantially the same or greater than the inner diameter of the tubular segment. The apparatus has the capacity to controllably stretch the flexible tubular segment sufficiently to facilitate passage therethrough of an end portion of a length of the tubing. The end portion of the length of tubing is then positioned inside the stretched flexible tubular segment such that the stretched tubular segment is located a pre-selected distance from the free end of the end portion of the length of tubing. The tubular segment is then allowed to contract around the the end portion. The assembled tubular segment and end portion of the length of tubing are then ejected from the apparatus while maintaining the pre-selected distance of the tubular segment from the free end of the end portion of the length of tubing.
摘要:
An apparatus and method are disclosed for modifying a liquid enteral nutritional product during delivery thereof from a supply to a feeding tube delivering the modified liquid enteral nutritional product to the gastrointestinal tract of a patient. At least one beneficial agent not in controlled release dosage form in a useful, dose unit, amount, is disposed within a formulation chamber so as to be taken up in a liquid enteral nutritional product traversing the formulation chamber while feeding the modified nutritional product into the gastrointestinal tract of a patient. The beneficial additive(s) are selected from nutrients, medicaments, probiotics, or diagnostic agents, or mixtures thereof, each in a dosage form that is dispersible in the medium of the liquid enteral nutritional product in less than two hours.

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.
摘要:
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.
