Abstract
Abstract An infant feeding device (10) disclosed includes a flexible elongated tube (12) including a longitudinal bore (14) therethrough for delivering liquid into the stomach of an infant. The tube (12) has an inlet (16) which is connected to a reservoir of the liquid, an intermediate portion (18), and an outlet (20) which includes a plurality of the laterally extending ports (22) so that the liquid may be delivered outwardly therethrough into the infant's stomach. A pliable plastic tip (24) including a cavity (30) having a fluid therein is affixed to the outlet (20) and protects delicate membranes and tissues of the infant as the feeding device is inserted into the nasogastric passages.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
240 words
An infant feeding device for nasogastric feeding, the feeding device comprising: a flexible, elongated tube including a longitudinal bore therethrough for delivering liquid into the stomach of the infant, the elongated tube having an inlet for communicating the tube to a reservoir of the liquid, an intermediate portion connected to the inlet for delivering liquid through the bore, and also having an outlet including a terminal end connected to the intermediate portion, the outlet including a plurality of laterally extending ports communicated to the bore so that the liquid may be delivered outwardly through the ports into the stomach of the infant after insertion of the feeding device into the nasogastric passages of the infant; a plug member sealingly mounted in said terminal end of the outlet; a pliable plastic tip affixed to the terminal end of the tube; the tip including a sleeve portion mounting the tip on the terminal end of the tube, an annular rib adjacent the sleeve portion providing a seat for abutting engagement with the terminal end, a probe portion connected to the sleeve portion with the annular rib therebetween, the probe portion defined by a cavity therewithin of sufficient volume and being charged with gaseous fluid therein to impart sufficient pliability to said plastic, the cavity providing cushioning for the pliable tip thereby protecting delicate membranes and tissues of the infant as the feeding device is inserted into and removed from the nasogastric passages.
Claim 2
Dependent Claim
240 words
An infant feeding device for nasogastric feeding, the feeding device comprising: a flexible, elongated tube including a longitudinal bore therethrough for delivering liquid into the stomach of the infant, the elongated tube having an inlet for communicating the tube to a reservoir of the liquid, an intermediate portion connected to the inlet for delivering liquid through the bore, and also having an outlet including a terminal end connected to the intermediate portion, the outlet including a plurality of laterally extending ports communicated to the bore so that the liquid may be delivered outwardly through the ports into the stomach of the infant after insertion of the feeding device into the nasogastric passages of the infant; a plug member sealingly mounted in said terminal end of the outlet; a pliable plastic tip affixed to the terminal end of the tube; the tip including a sleeve portion mounting the tip on the terminal end of the tube, an annular rib adjacent the sleeve portion providing a seat for abutting engagement with the terminal end, a probe portion connected to the sleeve portion with the annular rib therebetween, the probe portion defined by a cavity therewithin of sufficient volume and being charged with gaseous fluid therein to impart sufficient pliability to said plastic, the cavity providing cushioning for the pliable tip thereby protecting delicate membranes and tissues of the infant as the feeding device is inserted into and removed from the nasogastric passages.
Claim 3
Dependent Claim
71 words
The infant feeding device of claim 1 wherein the plurality of laterally extending ports comprises a pair of laterally extending ports connected to the bore proximate the tip, the ports being disposed on opposing sides of the tube so that the liquid may be delivered and distributed outwardly through the ports from opposing sides of the feeding device after insertion of the feeding device into the nasogastric passages of the infant.
Claim 4
Dependent Claim
44 words
The infant feeding device of claim 1 wherein the intermediate portion of the feeding device includes positioning indicia so that the position of the feeding device in the nasogastric passages can be determined and monitored during insertion, feeding and removal of the feeding device.
Claim 5
Dependent Claim
32 words
The infant feeding device of claim 1 wherein the feeding device also includes a radio-opaque stripe located generally parallel to the bore so that the feeding device is visible through fluoroscopy equipment.
Claim 6
Dependent Claim
45 words
The infant feeding device of claim 1 wherein the feeding device also includes a luer slip adaptor connected to the inlet of the tube for delivering the liquid from the reservoir into the bore of the tube, the luer slip adaptor being reclosable after feeding.
Claim 7
Dependent Claim
19 words
The infant feeding device of claim 1 wherein the pliable tip is premanufactured prior to connection to the tube.
Claim 8
Dependent Claim
30 words
The infant feeding tube of claim 6, wherein the infant feeding device also includes an in situ molded solvent bond for affixing the tip to the outlet of the tube.
