Abstract
Abstract A safer, more comfortable and convenient enteral feeding system is disclosed. Features of the system include reversal of the male-female connections on a standard enteral feeding system, and a safety pressure relief on the male adapter of the feeding tube assembly. A double female-ended guide wire adapter enables accurate placement of the feeding tube in a patient with lubrication of the passage which is receiving the tube. The provision of male and female double-ended adapter tubes allows utilization of the invention with other standard feeding systems.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
77 words
An enteral feeding system comprising a feeding tube assembly having a feeding tube body containing perforations near one end thereof and having a tapered connector element on its other end adapted for coupling with a mating connector element of an administration set, and said feeding tube assembly removably receiving therein a semi-rigid guide wire having an attached double-ended tapered adapter which can be coupled with said tapered connector element and with the nozzle of an irrigation syringe.
Claim 2
Dependent Claim
77 words
An enteral feeding system comprising a feeding tube assembly having a feeding tube body containing perforations near one end thereof and having a tapered connector element on its other end adapted for coupling with a mating connector element of an administration set, and said feeding tube assembly removably receiving therein a semi-rigid guide wire having an attached double-ended tapered adapter which can be coupled with said tapered connector element and with the nozzle of an irrigation syringe.
Claim 3
Dependent Claim
44 words
An enteral feeding system as defined in claim 1, and said tapered connector element comprising a male element, and said double-ended tapered adapter comprising a double-ended female adapter to receive in one end the tapered connector element and in its other end said nozzle.
Claim 4
Dependent Claim
35 words
An enteral feeding system as defined in claim 1, and a mercury weighted flexible terminal on the feeding tube assembly remote from the tapered connector element and extending longitudinally beyond the region of said perforations.
Claim 5
Dependent Claim
29 words
An enteral feeding system as defined in claim 1, and the semi-rigid guide wire having a short highly flexible terminal end portion thereon remote from the tapered connector element.
Claim 6
Dependent Claim
78 words
An enteral feeding system as defined in claim 1, and an administration set separate from the feeding tube assembly and having a tapered connector element on one end thereof adapted to interfit with the tapered connector element of the feeding tube assembly, the administration set including a drip chamber having a spike at its end away from the tapered connector element of the administration set and further including a roller clamp to regulate flow through the administration set.
Claim 7
Dependent Claim
52 words
An enteral feeding system as defined in claim 1, and a pair of separate adapter tubes one having a pair of opposite end male tapered connector elements and the other having a pair of opposite end female connector elements whereby the feeding tube assembly is rendered adaptable with standard enteric feeding systems.
Claim 8
Dependent Claim
48 words
An enteral feeding system as defined in claim 2, and said double-ended female adapter comprising in its throat portion a fixed hub to which one end of said guide wire is attached centrally, and the hub having spaced radiating arms between which fluid from said syringe may flow.
Claim 9
Dependent Claim
104 words
In an enteral feeding system, a feeding tube assembly including a feeding tube body having perforations near one end thereof and having a tapered male connector element on the other end thereof away from the perforations, an administration set separate from the feeding tube assembly and having a tapered female connector element on one end thereof adapted to interfit with the tapered male connector element of the feeding tube assembly, and said male and female tapered connector elements by their respective positioning on said feeding tube body and said administration set preventing any interchangeability of these components with those of an intravenous feeding system.
Claim 10
Dependent Claim
104 words
In an enteral feeding system, a feeding tube assembly including a feeding tube body having perforations near one end thereof and having a tapered male connector element on the other end thereof away from the perforations, an administration set separate from the feeding tube assembly and having a tapered female connector element on one end thereof adapted to interfit with the tapered male connector element of the feeding tube assembly, and said male and female tapered connector elements by their respective positioning on said feeding tube body and said administration set preventing any interchangeability of these components with those of an intravenous feeding system.
Claim 11
Dependent Claim
67 words
In an enteral feeding system as defined in claim 8, and a guide wire to assist in inserting the feeding tube assembly into a patient and adapted to enter the bore of the feeding tube body removably and having on one end a permanently attached double-ended female adapter which may be coupled temporarily with said tapered male connector element and the tapered nozzle of a fluid syringe.
Claim 12
Dependent Claim
35 words
In an enteral feeding system as defined in claim 8, and a mercury weighted flexible terminal on the feeding tube assembly remote from the tapered connector element and extending beyond the region of said perforations.
