A hub component for a vented connector including a generally elongate cylindrical body having a first end and a second end. The first end of the hub component includes one or more fingers or clips for engagement with one or more vents of the vented connector. The second end of the hub component can be configured for compatible engagement with a carbon dioxide detector.

A gastric decompression apparatus includes a variable-volume container having a movable plunger. The movable plunger is slidably mounted within the containment barrel so as to vary the contained volume of the container. The movable plunger has a plunger body having at least one lumen extending therethrough, and a filter disposed within the lumen. The gastric decompression apparatus may have a larger diameter and a shorter length from the first end to the second end as compared to conventional elongated syringes having an equal volume to minimize the size of apparatus within an isolette for a neonatal patient, advantageously reducing crowding within the isolette, particularly when there may be numerous tubes, wires, and monitors present for treating the neonatal patient. A gastric decompression system includes the gastric decompression apparatus and a catheter coupled to the container. A method of providing gastric decompression using the gastric decompression system is also provided.

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.

An adapter is provided for connecting a container of flowable material, such as enteral feed formula in a laminated paper container, to a feeding tube to enable bolus feeding. The adapter can transfer the flowable material from the container by piercing the container and/or a cover of the container. The adapter can form a fluid-tight friction seal on the container. In some embodiments, the adapter has a reusable tube vent long enough to be positioned in the air gap of the container when the container is inverted by a user.
