Single lumen gastro-intestinal feeding-decompression tubes
First Claim
1. A feeding and aspirating device comprising:
- a unitary elongate tube having a tube wall defining a central lumen, the tube having a distal end portion for placement within a patient'"'"'s digestive system, a proximal end for placement exterior to the patient and a central portion of predetermined length, the central portion having an aspirating zone extending over a segment of the central portion proximate to the distal end portion, the aspirating zone having at least two openings between the central lumen and an area exterior to the tube, a first of the two openings at a first longitudinal distance from the distal end portion and a second of the two openings at a second longitudinal distance from the distal end portion, the second distance different than the first distance; and
a feeding orifice in the distal end portion for communication between the central lumen and a feeding area exterior to the tube, the feeding orifice having a one way valve allowing a solution to pass through the tube and exit the feeding orifice and preventing substantially any flow into the central lumen through the feeding orifice.

Abstract
The present invention provides a single lumen gastro-intestinal tube for use in both delivering nutrition into the gastro-intestinal tract and aspirating excess materials from the gastro-intestinal tract. The single lumen tube may be delivered into the gastro-intestinal tract transnasally or surgically. The single lumen tube in accordance with the present invention includes a one-way valve which permits nutrition or other fluids to flow out of the tube and into the gastro-intestinal tract but which closes to prevent materials from being aspirated from the gastro-intestinal tract through the one-way valve. The single lumen tube also includes aspiration pores located proximately from the one-way valve. The aspiration pores perform the aspiration of air and excessive materials from the gastro-intestinal tract. Preferably, the aspiration pores are sized so as to filter any solids present in the gastro-intestinal tract from the aspirated material. A single lumen tube in accordance with the present invention may be used in alternating the delivery of nutritional or other materials to the gastro-intestinal tract and the aspiration of air and excessive material from the gastro-intestinal tract.

11. A feeding and aspirating tube for use in a patient'"'"'s intestine, the tube comprising:
-
a distal end located at the terminus of the feeding tube, the distal end comprising a one-way valve;
an aspirating zone located proximate to the distal end;
a plurality of pores within the aspirating zone, a first pore at a first longitudinal distance from the distal end and a second pore at a second longitudinal distance from the distal end, the second distance different than the first distance;
a central lumen communicating between the pores and the one-way valve at the distal end; and
a proximal end for attachment to feeding and aspirating equipment. - View Dependent Claims (12, 13, 14, 15)
