1.Connect the drain hose to stomach parts of the torso model.
1) Remove the skin from the body in order to see the stomach parts inside.
2) Hold the right side of the torso and put something (e.g. tissue box) between the left edge
of the frame and the table.
3) Connect the drain hose to stomach parts steadily.

In case training requires to keep the level of water in the stomach and does not require feeding
liquid formula to the simulator, such as use of a bumper type PEG tube or training of
confirmation of NG tube placement, close the drain port with the included plug instead of
connecting the drain tube.
Insert the plug firmly
into the drain port of
the stomach.
Turn up the rim of the plug. Ready for training.

Training Training procedure
Intranasal tube feeding
1.Inserting catheter
Spray silicone-based lubricant onto the catheter and into the nasal cavity.
Shortage of lubricant will cause difficulties in inserting the catheter. Do not use gel lubricants
or other types because they will dry and remain in the simulator.
We recommend 14 Fr catheters for this simulator. Larger catheters will result in
unsuccessful insertion.
In this simulator, catheter will reach the stomach after 50cm insertion.
Caution

2.Training the fixation of the catheter with tape
Do not leave the tape on the skin of the simulator. If the tape is left adhered for a
prolonged period of time, the skin surface will remain sticky from adhesive of the
tape.
If you fix the catheter with tape, do not start to inject the nutrient solution
immediately as the tape is still easy to come loose. Wait for afew minutes until
the tape will be tightly fixed.

Training Training procedure
After injecting the nutrient solution
1. After injecting the nutrient solution
In case of intranasal tube feeding andPEG procedure, drain the content from the stomach for
each injection of a package of nutrient solution.
1) Move the torso to the edge of the bed.
2) Hold the torso with both handsand tip it to drain the content.
3) Remove the skin and pull out the PEG catheter.
4) Refill the stomach with 300cc water for the next training.
2PEG procedure
1. Fixing PEG catheter
Fix the balloon catheter for PEG with
about 5ml air. Do not use water or any
liquid.
5 ml is the guide value for the recommended
balloon catheter for PEG “NIPRO 20Fr PEG
button catheter”. For other catheters, fill the
amount of air which is sufficient to anchor the
catheter to the PEG hole. )

Be careful not to slip or drop the torso when lifting and tilting it. Use its two handling holes.
After training that uses the plug for drain port
Lift the side of drain port and pull and remove the plug upwards, while taking care not to spill water. Then
tilt the torso above a container to discard the water from the stomach. Be careful that the discarded water
won't flow out of the caching container through the edge guard of the plastic frame.

Then, pull out the NG tube from the torso.
(PEG catheter )
Inject the mildly hot water to the PEG catheter with a syringe to clean the inside of the tube
and catheter. Then, pull out the PEG catheter or tube from the torso.
In case of afixed PEG catheter, insert the
syringe to the catheter valve and remove the
air. Then pull out the PEG catheter carefully
from the torso.
