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:・ This model has been manufactured to feel like a living human body to the touch. Improper
handling may cause damage.
・ Be sure to use ultrasound gel when using a probe. In addition, applying the probe to theinternal jugular and subclavian venous puncture sites with excessive force may cause
indentations or cuts to the puncture site surface.
・ Please do not place objects on the main body of the training model. Doing so may deform themodel.
・ Wipe away difficult-to-remove stains with gauze soaked in water or a neutral cleanser that has
been diluted with water. Do not use solvents such as paint thinner or benzene. Doing so may
cause discoloration or deformation of the training model.
・ Do not use oil-based inks, paints or similar substances on this product under any
circumstances. Doing so will cause stains that cannot be removed.
・ In producing the internal jugular and subclavian venous puncture sites, our priority was torecreate a realistic puncture sensation and lifelike skin. Intensive puncture of any specific partof the blood vessel alone may require replacement of the puncture site much sooner. Avoid
repeated use of the same part of the puncture site to the greatest extent possible.
* Using a hypodermic needle wider than 20 G may require replacement of the puncture site much sooner.
If at all possible, use a 20 G or narrower hypodermic needle.

・ The holes that result from puncturing the internal jugular and subclavian venous puncturesites will not close up. Creating punctures near puncture holes, applying the probe with force
to the puncture sites or creating pressure within the blood vessels by means such as pressing
the bulb of the blood bag will cause simulated blood to seep out. When this occurs, wipeaway the simulated blood and continue use.
・ This model has been manufactured for the purpose of practicing exploratory puncture.
The model cannot be used for main puncture, guide wire insertion, dilator insertion, scalpel
incision or catheter insertion.
・ Store in a place where the product will be protected from direct sunlight and ultraviolet
radiation. Long-term exposure to direct sunlight or ultraviolet radiation will cause discolorationof the product.
・ Store the product in its bag when it is not in use.
・ This product is intended for use in standard operating environments. Do not use it in heavy
industrial settings.
・ This model uses urethane foam for some of its parts, and may be susceptible to damage frompests that are attracted to urethane foam (such as insects in the ant family).
When storing this model, ensure that thorough measures are taken to prevent pest damage
before storing. The company will not be involved with or held liable for pest damage thatoccurs during storage.

53. How to Set-up the Internal Jugular and Subclavian Puncture
Sites for Ultrasound※ A special material is used for the puncture sites in order to achieve a realistic puncture sensation. As a result,the surfaces of the puncture sites are sticky. Before use, wash with a neutral cleanser that has been diluted withwater or wipe the surfaces of the puncture sites with ethanol or a similar substance.
※ A special polymer material has been used for the puncture sites, with ultrasonic characteristics differingfrom that of a human body. When using this product, please adjust the sensitivity of the ultrasound imaging
equipment you are using accordingly. Depending on the type of ultrasound imaging equipment you are using,it may not be possible to obtain a clear image even when the equipment is adjusted to the same sensitivity.

1. Attach the white connectors of the internal jugular venous puncture site for ultrasound(referred to hereafter as the 'internal jugular venous puncture site') and the subclavian venouspuncture site for ultrasound (referred to hereafter as the 'subclavian venous puncture site') to theconnectors of the blood bag.
※ Leakage may occur if the connection is not tight. Please ensure that you have made a secure connection.
