Feeding tube assembly
First Claim
Patent Images
1. A feeding assembly having a flexible tube of predetermined diameter for selective enteric administration and aspiration of fluids to and from the gastrointestinal tract of a patient, the tube having a proximal end joined to an enteric feeding bag, and a distal end, comprising in combination:
- a non-collapsible bolus positioned at the distal end of said tube, said bolus having a tapered frustoconical distal end and a tapered proximal end, said bolus having its largest diameter between said proximal and distal portions, said bolus having a diameter greater than the diameter of said tube, said bolus also having a first internal channel in fluid communication with said tube, said bolus possessing at least one outside opening in fluid communication with said first channel whereby said tube and said bolus can selectively accommodate fluids introduced thereto from said bag to exit said bolus for enteric feeding and through said tube and said bolus to facilitate aspiration of fluids from the gastrointestinal tract of a patient; and
an elongated weighted guide tip located distal to said bolus, said guide tip having a diameter less than the diameter of said bolus.

Abstract
A feeding assembly for the administration of fluids to a patient comprising a tube having a rigid bolus near its distal end to facilitate the peristaltic movement of the assembly during insertion. The bolus has openings for fluid flow, said openings are oriented to prevent the tip of a stylet from escaping from the tube assembly to minimize the possibility of injury to a patient during stylet intubation.

9. A feeding assembly having a flexible tube of predetermined diameter for selective enteric administration and aspiration of fluids to and from the gastrointestinal tract of a patient, the tube having a proximal end joined to an enteric feeding bag, and a distal end, comprising in combination:
-
a non-collapsible bolus positioned at the distal end of said tube, said bolus having a tapered frustoconical distal end and a tapered proximal end, said bolus having its largest diameter between said proximal and distal portions, said bolus having a diameter greater than the diameter of said tube, said bolus having a first internal channel in fluid communication with said tube, said bolus having a second internal channel extending transversely to and in fluid communication with said first channel, said first channel terminating in said second channel, said second channel having oppositely faced outside openings, said second channel having a diameter at least as large as the internal diameter of said tube, the portion of said bolus distal to said second channel being tapered to the diameter of said guide tip; and an elongated weighted guide tip located distal to said bolus, said guide tip having a diameter less than or equal to the diameter of said tube, said guide tip encasing non-toxic rod-like weighted segments.
