A nasogastric or orogastric feeding tube tip 50 comprises a body provided with an aperture 56 in a sidewall thereof through which feed can be given to a patient, and through which a sample of stomach content can be aspirated. The outer wall 58 of the main body additionally comprises at least one recess or groove 60, 62 which intersects the aperture 56, and which extends at least partially around or along the exterior surface of the main body. In use the recess or groove 60, 62 prevents or inhibits an aperture-occluding seal between the stomach wall 30 and the feeding tube tip being formed, especially when a vacuum is applied to the feeding tube 20 during an aspiration procedure. In one preferred embodiments a plurality of recess or grooves are provided, some of which extend radially around the circumference of the tube and others of which extend along the longitudinal axis of the tube. The recess or grove may alternatively follow a serpentine or helical path around the body of the tip (Fig 7). The recess or groves are further provided as a capillary in one embodiment (Fig 7).
