Abstract
Aspects of the present invention relate to a multi-lumen tube including a plurality of channels having a proximal end, a distal end and a length therebetween, wherein the plurality of channels comprises a first channel forming a feeding lumen, and a second channel forming a monitoring lumen, and each channel extends parallel to each other along at least a portion of the length of the tube, and wherein the proximal end is positioned outside of a subject's body and the distal end is positioned in the subject's stomach.
Claims27
A gavage tube comprising:
- a multi-lumen tube comprising a plurality of channels having a proximal end, a distal end and a length therebetween;
- wherein the plurality of channels comprises a first channel forming a feeding lumen, and a second channel forming a monitoring lumen, and each channel extends parallel to each other along at least a portion of the length of the tube;
- and
- wherein the proximal end is positioned outside of a subject's body and the distal end is positioned in the subject's stomach.
The gavage tube of any preceding claim, wherein the multi-lumen tube has an inner diameter ranging between 0.5 and 8.0 mm.
The gavage tube of any preceding claim, wherein the plurality of channels comprises a third channel forming a venting lumen.
A method of providing nutrition to a subject, comprising:
- inserting a gavage tube comprising:
- a multi-lumen tube comprising a plurality of channels having a proximal end, a distal end and a length therebetween through a nasal or oral cavity of the subject;
- wherein a first channel forms a feeding lumen having a proximal opening and distal axial opening in the multi-lumen tube, a second channel forms a monitoring lumen having a proximal opening and one or more lateral openings in the multi-lumen tube comprising one or more sensors positioned in each opening, and each channel extends parallel to each other along at least a portion of the length of the tube;
- and wherein the proximal end of the multi-lumen tube is positioned outside of a subject's body and the distal end is positioned in the subject's stomach, and;
- providing nutrition through the feeding lumen;
- and
- measuring at least one biometric of the subject with the one or more sensors during the step of providing nutrition through the feeding lumen.
A method of providing nutrition to a subject while simultaneously venting gas from the subject's stomach, comprising:
- inserting a gavage tube comprising:
- a multi-lumen tube comprising a plurality of channels having a proximal end, a distal end and a length therebetween through a nasal or oral cavity of the subject;
- wherein a first channel forms a feeding lumen having a proximal opening a distal axial opening in the multi-lumen tube, a second channel forms a monitoring lumen having a proximal opening and one or more lateral openings in the multi-lumen tube comprising one or more sensors positioned in each opening;
- and a third channel forms a venting lumen having a proximal opening and a plurality of lateral vent holes in the multi-lumen tube, and each channel extends parallel to each other along at least a portion of the length of the tube;
- and wherein the proximal end of the multi-lumen tube is positioned outside of a subject's body and the distal end is positioned in the subject's stomach, and;
- providing nutrition through the feeding lumen;
- allowing the venting lumen to facilitate removal of gases from the subject's stomach during the step of providing nutrition through the feeding lumen;
- measuring at least one biometric of the subject with the one or more sensors during the step of providing nutrition through the feeding lumen.
