The present invention provides an intubation assembly for nasogastric intubation comprising a catheter and a plastic sheath tube for encasing the catheter along substantially the full length thereof, the sheath tube having a longitudinal tear-off line over the full length thereof and having elasticity and rigidity slightly greater than the catheter which is slidably inserted in the sheath tube.

A medical intubation assembly a distal end of which is adapted to be inserted internally of a patient, said assembly comprising a relatively soft catheter of a first relatively small diameter and having a length to reach from externally of the patient to a desired point internally of the patient; a relatively rigid longitudinally splittable insertion tube of a second and relatively larger diameter and having an internal bore slidably receiving and encasing said catheter, said insertion tube having, and being splittable along, two opposed longitudinally extending lines of weakness along the full length thereof to facilitate splitting thereof for withdrawal from the patient and removal from about said catheter; and a catheter fixing means adapted to be removably fixed adjacent a proximal end of said catheter externally of the patient for fixedly positioning said catheter during withdrawal of said insertion tube from the patient and removal of said insertion tube from about said catheter, said catheter fixing means including a plate means adapted to abut the patient adjacent the location of insertion of the intubation assembly, the catheter fixing means including a catheter receiving groove having a diameter slightly smaller than said first diameter for pinching engagement with said catheter during withdrawal and removal of said insertion tube from about said catheter, portions of said plate means positioned on opposite sides of said groove to abut each of the split halves of said insertion tube upon withdrawal thereof to assist in separating and splitting of said insertion tube along said longitudinally extending lines.
