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 withthe 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 humanbody and does not indicate poor quality. The distinct odor fades over time. There may also be a smellof 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 inthe protective sheet (provided as an accessory) before storage. If it becomes too sticky after use orafter washing, it may be difficult 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 theprotective 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 thepart 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 affect 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9.		 In caring for the model, do not use rubbing alcohol, thinners, or benzin or other organic solventson 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. For the power supply, always use the AC adapter provided as an accessory.
13. 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.
14. 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 andsags.
15. 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, awayfrom direct sunlight.
16. 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.

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 duringstorage.

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 inflated with air as a substitute for amniotic fluid; thus, reproducing ahighly 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 andtexture that closely simulates human skin, for realistic practice.
2. The model contains a pelvis that enables realistic palpation to check the pubic symphysis andthe ilium during uterine fundal height measurement and external pelvimetry, with a sensationthat closely resembles an actual human body.
3. The amnion can be filled with air to make handling and control easier. The air pressure level ofthe air in the amnion can be checked with an indicator and adjusted to change the palpation
sensation.
4. An internal synthesizer enables auscultation of a realistic fetal heartbeat sound. The volume andspeed are freely adjustable.
5. Traube stethoscope monitoring of the fetal heartbeat can be practiced. The heartbeat sound canalso be emitted from a speaker on the side of the panel.

body to outside the body, and set the fetus in amnion in the body.
		 *The position and orientation of the fetus in amnion can be readily adjusted. When setting
it in the breech presentation, place the air feed tube in the groove on the inside of the		 body so that it does not interfere.

the amnion indicator is the maximum level for filling the amnion with air. The blue line
indicates the current volume of air. To add air, pump air into the amnion using the rubber
bladder. To remove air, twist the valve on the rubber bladder counter-clockwise to loosen it.
		 *Filling the amnion with a volume of air that exceeds the red line (maximum) on the 		
amnion indicator may cause the amnion to rupture. Be sure to maintain the air volume 		
below the red line (maximum).

[REFERENCE]
As the volume of air in the amnion becomes larger, the situation where palpation is moredifficult can be simulated. Using a smaller volume of air simulates the situation where
palpation is easier. Adjust to suit the situation.

AC adapter jack5) After adjusting the volume of air in the amnion, set the amnion indicator stopcock in the
direction of the tube on the main body side (the direction shown by the red arrow in theillustration) 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 theAC adapter jack on the panel. Plug in the cord, andPowerswitchPower switch

fetal heartbeat with the HEART RATE dial. The SPEAKER switch is used to switch emissionof the fetal heartbeat sound to an external speaker.

To remove the air, turn the amnion indicator stopcock back in the opposite direction of theamnion indicator (the direction shown by the red arrow in the picture), and twist the valve on
the rubber bladder counter-clockwise to loosen it.

*1. The abdominal wall protective sheet prevents the oil component from oozing out of theabdominal 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.
