A feeding tube device for postpyloric feeding comprises a bendable feeding tube having a proximal end, a central portion and, and a distal end and a delivery lumen for conducting a digestible substance. A proximal tube holder structure is adapted to be connected to the proximal end and to a control box and has a feeding port for receiving the digestible substacnce. A tilting mechanism has a tilting wire mechanically connected to said distal end and a knob coupled to said proximal tube holder structure for maneuvering said tilting wire so as to tilt the distal end in relation to the central portion. At least one image sensor is mounted on a front tip of the bendable feeding tube and connected to a communication cable passing through the proximal tube holder structure for forwarding outputs of the at least one image sensor via a connector connected to the control box.
