A device for introducing a nasogastric tube in the stomach of anaesthetised or comatose patients by medical personnel is described. It consists of a curve-shaped plastic or rubber tube. It has two extensions 2, 3 at its proximal end 4 for holding it and to prevent it from being dislodged into the oesophagus during insertion of the NGT and a hair-line slit 5 along its side extending from its proximal end 4 to the distal end 6 for separating it from the nasogastric tube. The depth of the slit in the wall of the introducer is partially glued to prevent the tip of the nasogastric from leaving the introducer via the slit during insertion while allowing the nasogastric tube to be easily peeled off the introducer. |
