Gastric systems, apparatus, and methods for use with enteral feeding

A gastric pressure relief system comprising:

• a feeding container connected to an administration tubing;
• a relief tubing;
• a delivery tube in fluid communication with the administration tubing and the relief tubing;
• a multi-way connector having a first arm, a second arm, and a third arm, wherein
• the first arm is connected to the relief tubing,
• the second arm is connected to the delivery tube, and
• the third arm is connected to the administration tubing;
• a collection reservoir in fluid communication with the relief tubing, wherein
• the collection reservoir includes a vent configured to allow gas to pass through in both directions and configured to restrict the flow of liquid through the vent, wherein the vent comprises a top membrane and a side membrane,
• the collection reservoir is configured to collect reflux fluids from a patient's stomach via the relief tubing, and
• the collection reservoir comprises volumetric indicia configured to represent a volume of reflux fluids received from the patient's stomach;
• and
• a flow regulator adapted to regulate flow within the relief tubing.
