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 skin is made of a special silicone with a texture that is similar to human skin, and the abdominal
wall piece is made with a special material that is soft to the touch. Please handle these models with
the same care that you would exercise when working with a human body. Applying excessive force
may damage the model.
2. The material of the abdominal wall piece has a distinct odor. This odor is not harmful to the human
body and does not indicate poor quality. The distinct odor fades over time. There may also be a smell
of baby powder remaining on the model, as baby powder is applied during fabrication.
3. The abdominal wall piece may become sticky due to the oil component. Always place it correctly in
the protective sheet (provided as an accessory) before storage. If it becomes too sticky after use or
after washing, it may be di󱐰cult to set the skin in place. In these cases, apply baby powder (provided
as an accessory) liberally to the abdominal wall piece.
*See “Caring for the Model” on page 10.
4. The skin may become sticky from the oil component in the abdominal wall piece. If this happens,
wash the skin in water to remove the oil before use.
To prevent the oil from getting onto the skin, always place the abdominal wall piece correctly in the
protective sheet (provided as an accessory) before storage.
*See “Caring for the Model” on page 10.
5. The abdominal wall piece may change its shape over a prolonged period. Check the shape of the
part about three years after purchase. If it is deformed to the extent that its function is affected,
consider replacing it.
6. Air bubbles or impressions in the abdominal wall piece that may remain from the fabrication process
do not a󱐯ect the strength of the material, as the material used is tear-resistant.
7. Do not use oil-based inks, pencil, chalk, or paints on the model because they may cause permanent
staining.
8. Please do not use oily lubricant (baby oil, olive oil etc.), alcohol lubricant, and lubricant containing
organic solvent. These may cause breakage of the model.

1. The contents of this instruction manual are subject to change without notice.
2. This instruction manual may not be reproduced in part or in its entirety without permission.
3. Please contact the manufacturer in the event that any errors or omissions are found in the contents of
this instruction manual.
4. This product should be used only as described in this instruction manual. In particular, the product
should not be used in any way that contravenes the precautions noted in the instruction manual.
9. In caring for the model, do not use rubbing alcohol, thinners, or benzin or other organic solvents
on the model, as doing so may cause damage.
10. Do not use the model outdoors or in damp places; doing so may damage the model.
11. Placing objects directly on top of the model or placing it on uneven surfaces may cause
deformation.
12. An excessive amount of air injected into the amnion may damage the amnion. When injecting air,
palpate the abdomen of the model to check the tension in the amnion.
13. When setting the skin on the body, the skin may have wrinkles or sags due to the construction of
the model. Please note that it may not always be possible to completely remove these wrinkles and
sags.
14. Storing the model for an extended period in a high or low temperature environment or under
exposure to direct sunlight may cause the oil component in the abdominal wall piece to ooze out,
causing deformation or discoloration of the model. If possible, store the model at 10-50°C, away
from direct sunlight.
15. Take care to avoid touching the internal parts through the gap between the panel and the body;
doing so may cause the internal electronic device to malfunction.
16. This product is intended for use in standard operating environments. Do not use it in heavy industrial
settings.
17. This model uses urethane foam for some of its parts, and may be susceptible to damage from pests
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 that occurs during
storage.

1. Outline and Features
Outline
The four types of Leopold’s Maneuvers, fetal heartbeat monitoring, and abdominal
measurement can be practiced. The abdominal wall piece is made of soft, stretchy material,
and the abdomen can be inated with air as a substitute for amniotic uid; thus, reproducing a
highly realistic sensation. An internal synthesizer reproduces a realistic fetal heartbeat sound.
Volume and speed are adjustable.
Features
1. The trunk skin and fetus material are made of a special silicone rubber with an appearance and
texture that closely simulates human skin, for realistic practice.
2. The model contains a pelvis that enables realistic palpation to check the pubic symphysis and
the ilium during uterine fundal height measurement and external pelvimetry, with a sensation
that closely resembles an actual human body.
3. The amnion can be lled with air to make handling and control easier.
4. An internal synthesizer enables auscultation of a realistic fetal heartbeat sound. The volume and
speed are freely adjustable.
5. Traube stethoscope monitoring of the fetal heartbeat can be practiced. The heartbeat sound can
also be emitted from a speaker on the side of the panel.

3-3. Attach the skin
1) After anchoring the abdominal wall piece to the xation pins, place the skin over the main
body.
*Do not secure the hook and loop fasteners on the sides at this time.
2) Open the two-way stopcock.
3) Twist the valve on the rubber bladder clockwise to close it, and ll the rubber bladder with air.
[Caution]
When an excessive amount of air is injected into the amnion, the amnion may burst. When
injecting air, feel the abdomen of the model to check the tension in the amnion.
[REFERENCE]
As the volume of air in the amnion becomes larger, the situation where palpation is more
di󱐰cult can be simulated. Using a smaller volume of air simulates the situation where
palpation is easier. Adjust to suit the situation.

9
5) After adjusting the volume of air in the amnion, close the two-way stopcock to prevent air
from leaking out of the amnion.
*If this step is skipped, air will slowly leak out of the amnion over time.
6) Secure the hook and loop fasteners in four places on each side of the skin.
Smooth down the skin vertically and horizontally to push wrinkles and sags on the abdomen
outwards. Pull the skin taut and secure the hook and loop fasteners.
*Depending on the volume of air injected, it may not always be possible to completely
remove these wrinkles and sags.
3-4. Turn on the power
1) Connect the AC adapter *connector to the AC adapter jack on the panel. Plug in the cord, and
press the power switch on the panel.
2) Adjust the fetal heartbeat volume with the VOLUME dial on the panel, and the speed of the
fetal heartbeat with the HEART RATE dial. The SPEAKER switch is used to switch emission
of the fetal heartbeat sound to an external speaker.

4. Caring for the Model
(1) Remove the air from the amnion before storing.
To remove air, open the two-way stopcock, and twist the valve on the rubber bladder
counterclockwise to loosen it.
(2) Wrap the abdominal wall piece in the abdominal wall protective sheet provided as an
accessory, then place it back on the main body and place the skin over the top to store.
*1. The abdominal wall protective sheet prevents the oil component from oozing out of the
abdominal wall piece to the skin and other parts.
*2. If the oil component contained in the abdominal wall piece oozes out to the skin and
other parts, it will promote deterioration of the product. Be sure to wrap the abdominal
wall piece in the abdominal wall protective sheet for storage.
*3. If the abdominal wall piece becomes sticky, apply the baby powder provided as an
accessory generously to the piece.
(3) If the model becomes dirty, wipe it with a moist gauze or similar soft material using a neutral
solvent diluted with water.
*Do not clean it with rubbing alcohol, thinners, benzene, or other organic solvents.
(4) Place the model in the proper orientation when storing to prevent deformation.
(5) Storing the model for an extended time in a high or low temperature environment, or under
exposure to direct sunlight, may cause the oil component in the abdominal wall piece to ooze
out, causing deformation or discoloration of the model. If possible, store the model at 10-30°C,
away from direct sunlight.
(6) Place the model in the storage bag provided as an accessory when storing.
