Abstract

Abstract A nasogastric feeding tube for enteral alimentation or feeding within the intestine of a patient with a nutrient solution is disclosed. The feeding tube includes a dispensing tube which is located in the stomache of a patient. A number of slits are located along the dispensing tube and the nutrient solution is dispensed through these slits. A conducting tube is connected to the dispensing tube. The conducting tube passes out of the nose of the patient and is connected to a suitable source of nutrient solution. The conducting tube has a substantially smaller outside diameter than the outside diameter of the dispensing tube to provide greater patient comfort and fewer medical complications. A non-slitted portion of the dispensing tube is provided at the distal end thereof so that the distal end of the dispensing tube has sufficient inherent strength to be easily inserted into the nose of the patient. The distal end of the dispensing tube can also be provided with a weight. A radiopaque stripe and distance marks can further be provided on the conducting tube for accurate locating of the conducting tube and dispensing tube in the patient.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 190 words
A nasogastric feeding tube for enteral alimentation of a patient with a nutrient solution comprising: an integral tube including a dispensing tube portion and conducting tube portion, the dispensing tube portion having an outside diameter larger than the outside diameter of the conducting tube portion, means forming a plurality of slits in said dispensing tube portion located along at least a portion of the length thereof so as to define a slitted portion of said dispensing tube through which the nutrient solution is dispensed, said slit forming means comprising for each slit a pair of spaced circular holes with said spaced holes being interconnected with a longitudinally extending narrow opening to prevent malfunction of the tube from occlusion of the openings, the distal end of the dispensing tube portion being unslitted to provide sufficient inherent strength to be easily inserted into the nose of the patient, a weight disposed in the distal end of the dispensing tube portion, the conducting tube portion having the proximal end adapted to be connected to a source of nutrient solution, the conducting tube portion adapted to pass out of the nose of a patient.
Claim 2
Dependent Claim 190 words
A nasogastric feeding tube for enteral alimentation of a patient with a nutrient solution comprising: an integral tube including a dispensing tube portion and conducting tube portion, the dispensing tube portion having an outside diameter larger than the outside diameter of the conducting tube portion, means forming a plurality of slits in said dispensing tube portion located along at least a portion of the length thereof so as to define a slitted portion of said dispensing tube through which the nutrient solution is dispensed, said slit forming means comprising for each slit a pair of spaced circular holes with said spaced holes being interconnected with a longitudinally extending narrow opening to prevent malfunction of the tube from occlusion of the openings, the distal end of the dispensing tube portion being unslitted to provide sufficient inherent strength to be easily inserted into the nose of the patient, a weight disposed in the distal end of the dispensing tube portion, the conducting tube portion having the proximal end adapted to be connected to a source of nutrient solution, the conducting tube portion adapted to pass out of the nose of a patient.
Claim 3
Dependent Claim 23 words
A nasogastric feeding tube as claimed in claim 1 further including a radiopaque stripe located along the length of said conducting tube portion.
Claim 4
Dependent Claim 25 words
A nasogastric feeding tube as claimed in claim 1 further including distance marks located at spaced intervals along the length of said conducting tube portion.
Claim 5
Dependent Claim 75 words
A nasogastric feeding tube as claimed in claim 1 further including a double-ended fluid connector located at the other end of said conducting tube portion, one of the ends of said double-ended connector being normally attached to the source of nutrient fluid and the other end of said double-ended connector normally having a removable plug inserted therein whereby after removal of the plug other sources of medicinal fluids are connectable to said conducting tube portion.
