Methods, systems, and devices are described for fabricating, providing, and using an orogastric tube. The orogastric tube may have, among other things: a proximal end section； a distal end section opposite the proximal end section and 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 into the distal end section； at least one suction channel extending from the proximal end section along a pre-determined length of the orogastric tube into the distal end section； and optionally 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 optional balloon channel is in communication with an expandable balloon in the distal end section； and a main channel encloses a pre-determined length of the sump channel, the suction channel, and, if present, the balloon channel.
