Handling and Safety Precautions
These precautions should be strictly observed in order to ensure safe, long-term
use of the product.
The following precautions should be observed particularly strictly:
1. The model is made to simulate the texture of human skin. Rough handling may cause damage.
2. Do not place objects on the model, as this will cause deformation.
3. To clean difficult-to-remove smudges or marks, wipe with moist gauze or similar material using a
neutral solvent diluted with water. Do not use thinners, benzene, or similar solvents.
4. Almost no uid leakage will occur when the simulated blood vessels, various injection sites, or skin are
punctured with a needle. However, sites that are punctured repeatedly will gradually begin to leak and
should be replaced with new parts as needed.
5. The IV opisthenar blood vessel tube and blood vessel tube degrade over time. Check the degree to
which they have degraded before use. If they are overly degraded, please replace them.
6. Use of thicker needles will shorten the life of the simulated blood vessels and injection sites.
7. When not in use, store the model away from direct sunlight and ultraviolet light.

1. Outline and Features
Outline
• Three di󱐯erent injection techniques—intramuscular injection, hypodermic injection, and
IV injection—can be practiced with this single model. Moreover, intravenous (IV) injection
can be practiced in the median antebrachial vein and opisthenar vein, allowing a total of
four di󱐯erent injection techniques to be practiced.
• With the simulated blood vessels wrapped in silicone gel, the vessels can more realistically
slip away during puncture or be punctured completely through, events that could not be
reproduced with the previous model.
Features
• Silicone is used in the skin and other main parts, so the look, feel, and puncture sensation
are similar to those of a real human body, which enables more realistic practice.
• Since four different techniques can be practiced with this single model, use of several
models as in the past is no longer necessary, and set-up and clean-up/re-storage times are
reduced.
• With a movable shoulder, elbow, and wrist, realistic body positions can be reproduced for
each technique.
• The skin (silicone) can withstand many punctures without leaving visible needle holes, and
thus is able to be used for a large number of practices.
• Blood can be removed with a vacuum blood collection tube or a syringe.

3. Stand Assembly
*When the Training Arm is delivered, the height-adjustable hook will be covered with a protective tube.
Do not discard this tube.
Remove the tube to use the hook during IV injections.
When practicing techniques other than IV injection, or when storing the Training Arm, cover the
hook with the tube. When left uncovered, the hook may be deformed or damage the storage bag.
1. Pull the stand pole upright.
2. Push the pole down until the base of the pole contacts the seat.
3. Turn the knob screw to fasten the pole.

5. Set-up for Hypodermic Injection
1. First apply baby powder to the surface of the hypodermic injection site, and then set the hypodermic
injection sponge in place.
2. Insert the hypodermic injection site into the acromial part installed in the main body.
3. Apply baby powder to the upper arm skin, and position on the main body.

6. Rotate the elbow 180°.
*Because of the structure of the Training Arm, the direction of rotation is opposite that of the
human body.
Use caution, as rotating the Training Arm in the incorrect direction may cause damage.
7. Pull back the skin, and attach the drainage tube to the drainage tube connector on the main body.
Place the tip of the drainage tube into a drainage receptacle.

10
8. The hypodermic injection setup is now complete.
*When performing IV injections after rst practicing hypodermic injections, drain and dispose of the
uid remaining in the hypodermic injection site before practicing IV injections.
*After practicing, dry the water from the hypodermic injection sponge well. Inadequate drying may
result in mold.
6. Care for Hypodermic Injection Parts
1. Remove the main body from the stand pole.
When attached to the pole, the main body can be removed by raising slightly and then pulling.
2. Take o󱐯 upper arm skin and remove hypodermic injection site and hypodermic injection sponge.
3. Squeeze gently to remove any uid remaining in the hypodermic injection site and sponge.
4. Dry moisture remaining in all components. Insu󱐰cient drying may lead to mold. After drying,
always apply baby powder. If this is not done, the skin and injection site may stick together and make
set up di󱐰cult the next time the Training Arm is used.
5. Wipe o󱐯 any uid remaining on the main body. If di󱐰cult-to-remove smudges or marks are present,
wash with water and dry thoroughly.

7. Rotate the elbow 90°
*Because of the structure of the Training Arm, the direction of rotation is opposite to that of the
human body.
Use caution, as rotating the Training Arm in the incorrect direction may cause damage to the model.
8. Pull back the upper arm skin, and attach the drainage tube to the drainage tube connector on the
main body, as for hypodermic injection. Place the tip of the drainage tube into a drainage receptacle.
(See 5. Setup for Hypodermic Injection, 7)
9. The intramuscular injection setup is now complete.
*When performing IV injections after rst practicing with the intramuscular injection site, drain and
dispose of the fluid remaining in the intramuscular injection gel bag before practicing the IV
injections.
*After practicing, dry the intramuscular injection sponge well. Inadequate drying may result in
mold.

9. Care for Intramuscular Injection Parts
1. Remove the main body from the stand pole.
When attached to the pole, the main body can be removed by raising slightly and then pulling.
2. Take o󱐯 upper arm skin and remove intramuscular injection gel bag and intramuscular injection
sponge.
3. Squeeze gently to remove the uid remaining in the intramuscular injection gel bag and sponge.
4. Dry moisture remaining on or in all components. Insu󱐰cient drying may lead to mold. After drying,
always apply baby powder. If this is not done, the skin and injection site may stick together and make
set up di󱐰cult the next time the Training Arm is used.
5. Wipe o󱐯 uid remaining on the main body. If di󱐰cult-to-remove smudges or marks are present, wash
with water and dry thoroughly.

11. Set-up for IV Injection
1. After applying baby powder to the IV injection site, pull out the tube connector (female) protruding
from the main body by about 3 cm, and insert the IV injection site connector.
After con rming a solid connection, set in place in the main body.
*When pulling the tube connector out (female) from the main body, be careful not to pull too far.
If pulled too far, the spring protecting the tube will be stretched.
*If the connection is not  rm, leakage may occur. Con rm that the  t is solid.
When attaching the IV injection site, grasp the respective connectors, insert the connector on the side
with the spring and turn in the direction shown in the diagram (about 45°) until it stops.
*Do not grasp the gel bag portion of the injection site when attaching and removing the site. This may
damage the injection site. Always grasp the connectors.
Rotate about 45°

2. Open the wrist cover, insert the opisthenar blood vessel tube in the groove in the back of the hand as
shown in the diagram, and close the cover.
*Be careful not to open the wrist cover too far. Damage may occur if the wrist cover is opened too
far or excessive force is used.
3. After applying baby powder to the forearm skin, place this skin on the main body.

A󱐰x the remaining hook-and-loop fasteners.
A󱐰x one side of the hook-and-loop
fasteners and arrange so that the skin is
aligned with the contour of the elbow.
Place the forearm skin over the main
body.
Set the opisthenar blood vessel tube in the
groove so that it is not pinched by the wrist
cover, and use caution when closing the cover.
