The invention provides an oral 
nutrition tube. The oral 
nutrition tube comprises a tube body, wherein a food inlet is arranged at the head end of the tube body; a food outlet hole is arranged on the end wall of the tube body; a 
silica gel guide head is integrally packaged at the end of the tube body; the 
tail end of the 
silica gel guide head is provided with a smooth spherical crown-shaped outer surface, and the 
hardness of the 
silica gel guide head is smaller than that of the tube body; the 
tail end of the tube body is encapsulated by a silica gel guide head, and the 
hardness of the silica gel guide head is smaller than the 
hardness of the tube body, and the 
tail end of the silica gel guide head is a spherical crown-shaped outer surface; when in use, the silica gel guide head guides the tube body into the 
human body, and when the silica gel guide head passes through the 
throat part, the spherical crown-shaped outer surface of the silica gel guide head contacts with the 
throat; and thesilica gel guide head material is relatively soft, and certain bending deformation will occur, so that the silica gel guide head can smoothly adhere to the wall and pass through the 
throat, thereby facilitating the 
intubation operation. Due to the smooth exterior and soft material of the silica gel guide head, the harm to 
human body is small, and the comfort degree of the patient is improved.
