10000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 aneutral solvent diluted with water. Do not use thinners, benzene, or similar solvents.
4. Almost no fluid 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 andshould be replaced with new parts as needed.
5. The IV opisthenar blood vessel tube and blood vessel tube degrade over time. Check the degree towhich they have degraded before use. If they are overly degraded, please replace them.

1. Outline and Features

Outline•Three different injection techniques—intramuscular injection, hypodermic injection, andIV 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 offour different injection techniques to be practiced.

•

With the simulated blood vessels wrapped in silicone gel, the vessels can more realisticallyslip 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 foreach technique.

•

The skin (silicone) can withstand many punctures without leaving visible needle holes, andthus is able to be used for a large number of practices.

•

Blood can be removed with a vacuum blood collection tube or a syringe.

11. Set-up for IV Injection
1. After applying baby powder to the IV injection site, pull out the tube connector (female) protrudingfrom the main body by about 3 cm, and insert the IV injection site connector.
After confirming 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 firm, leakage may occur. Confirm that the fit is solid.
Rotate about 45°

When attaching the IV injection site, grasp the respective connectors, insert the connector on the sidewith 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.

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.
Wrist coverSet the opisthenar blood vessel tube in thegroove so that it is not pinched by the wrist
cover, and use caution when closing the cover.

3. After applying baby powder to the forearm skin, place this skin on the main body.

Place the forearm skin over the mainbody.

Affix one side of the hook-and-loop
fasteners and arrange so that the skin isaligned with the contour of the elbow.

Affix the remaining hook-and-loop fasteners.

18

4. After applying baby powder to the hand skin, set it in place on the main body.

Cover the hand portion of the main bodywith the hand skin.

Affix with hook-and-loop fasteners.

5. Insert the joint protruding from the main body into the hole in the lower portion of the stand pole
until the flange makes contact with the pole.

7. After setting the irrigator connector on the end of the irrigator, lower to the stand.

*Insert the end of the irrigator firmly and deeply into the irrigator connector.
Not inserting the end of the irrigator firmly enough may result in leakage of simulated blood.

*Slide the hose clamp in the direction indicated above, then fasten the connector.

2112. Care for IV Injection
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. Return the simulated blood in the irrigator to its original container.
3. Remove the irrigator from the blood vessel tube, wash with water, and dry.
4. With the lid of one irrigator connector open, put the irrigator into the simulated blood container.
Close the lid of the other irrigator connector, attach an empty syringe to the end and push out thesimulated blood in the blood vessel tube with air.

The connector lid is a one-way valve that is
opened by inserting the end of a syringe.

5. After changing the connector from the simulated blood container to a drainage receptacle, fill thesyringe with water, and wash the inside of the blood vessel tube using the same technique as in 3
above.
*Do not press the syringe rapidly. This may push air or simulated blood into the IV injection site. If
that happens, use a syringe with a needle to suction out the air or simulated blood.
6. Remove the forearm skin and IV injection site, and wash with water. If any simulated blood is present
in the main body, wash it off as well. (There is almost no leakage from the IV injection site even ifpuncture occurs, but at times a small amount of leakage will occur on the skin surface when theneedle is withdrawn.)
7. Dry after washing. Be sure to always apply baby powder after drying. If baby powder is not applied,the next time the Training Arm is used, the skin and injection sites or fleshy parts may stick together
and make setup difficult.

2213. Replacement of the blood vessel tube, blood vessel connector and IV
opisthenar blood vessel tube
Blood vessel tube
1. Remove the old blood vessel tube from the gel bag and insert the new blood vessel tube deeply into
the connector protruding from the gel bag.
*When inserting the tube, maintain a grip on the base of the connector protruding from the gel bag
as much as possible. Gripping the gel bag makes it difficult to insert the blood vessel tube and may
damage the gel bag.
* If the insertion is not firm, leakage may occur. Confirm
that the insertion is solid.
