2. Fig 1
The light-aiding device which consisted of a tightly inserted small light bulb (1) into a nasogastric (NG) tube (2) after welding the bulb to an electric wire passing through the NG tube. The wire is connected to (3) an AC–AD adaptor. The emitted light (4) is in a forward and in a lateral direction.

3. Fig 2
SGTA device in the form of suction catheter injected with coloured solution (1) representing LA. The tip of the catheter is closed (2) and its nearby distal part is punctured for a distance of 15–17 cm. The tip and the punctured parts of the catheter are wrapped by the cotton gauze that will be soaked (coloured patches) with the injected solution (3).
