Methods, systems, and devices are described for fabricating and using an orogatric tube. The orogastric tube may have: a proximal end section； a distal end section opposite the proximal end section, the distal end having a flexible, resilient curved portion； at least one sump channel extending from the proximal end section along a pre-determined length of the orogastric tube to the distal end section； at least one balloon channel extending from the proximal end section along a pre-determined length of the orogastric tube to the distal end section, the balloon channel being in communication with an expandable balloon in the distal end section； and a main channel enclosing a pre-determined length of both the sump channel and the balloon channel.
