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:
Obstetric model - vulva II and the umbilical cord kit (for tying and cutting)
1. This model is made with a special material to simulate the texture of human skin. Please handle
it with the same care that you would exercise when working with a human body. Pulling it with
excessive force or subjecting it to strong impact, such as dropping it, may cause damage.
2. The material of this model has a distinct odor, which fades with time. This odor is not harmful
to the human body and does not indicate poor quality. There may also be a baby powder smell
remaining on the product, as baby powder is applied to the models during fabrication.
3. Wear disposable gloves when handling the model.
4. Use glycerin to lubricate the models. Be sure to apply a su󱐰cient amount of lubricant (glycerin)
to the model before use. Koken is not responsible for deterioration or damage occurring from
use of lubricants other than glycerin. Use commercially available glycerin if you run out of the
glycerin provided with the model.
5. Placing objects directly on top of the model or placing the model on uneven surfaces may result
in deformation.
6. Do not use rubbing alcohol, thinners, benzene or other similar organic solvents on the model, as
doing so may cause damage.
7. Do not use oil-based inks, pencil, chalk, or paints on the model, as they will soak into the material
and cannot be removed.
8. If the surface becomes sticky after washing the model, generously apply baby powder to the
model to reduce friction.
9. The model may lose its shape after a long period of time. Check the shape of the model around
3 years after purchase. If it is deformed to the extent that functioning is a󱐯ected, please consider
ordering a replacement.
10. Air bubbles or impressions in the model that may remain from the fabrication process do not
a󱐯ect the strength of the material, as the material used is highly tear-resistant.
11. This model is washable. After washing, wipe o󱐯 the remaining water with a soft, dry gauze or
cloth, and pat baby powder all over the model. (Do not clean the model with rubbing alcohol,
thinners, benzene or other similar organic solvents.)

2
12. Storing the model for an extended time in a high or low temperature environment may result
in deformation. Exposure to direct sunlight or UV rays may also alter its shape or color. Store the
model in a 0-50°C environment, in a place where it will not be exposed to direct sunlight or UV
rays.
13. Oil may leak from the model. For proper storage, wrap the model in paper towels, gauze, or
another type of cloth, and place it in the re-sealable plastic bag that came with the kit.
Fetal model and placenta model
1. Please handle this model with the same care that you would exercise when working with a
human body. Excessive force may result in damage to the model.
2. When delivering the placenta, avoid pulling too strongly on the umbilical cord.
3. Using the umbilical cord clip on the placenta model umbilical cord may cause it to tear. Use the
umbilical cord clip on the umbilical cord for tying and cutting.
4. Clamping the placenta model umbilical cord tightly with hemostatic forceps or clamping with
the base of the grip may tear the model. When using hemostatic forceps on the placenta model
umbilical cord, clamp lightly and avoid using the base of the grip.

5. Wash smudges or marks o󱐯 the model with water. To clean stubborn smudges or marks, wash
with a neutral solvent diluted with water. After washing, wipe o󱐯 the remaining water with a
soft, dry gauze or cloth.
*Do not clean the model with rubbing alcohol, thinners, benzene or other similar solvents.
6. Dropping the model or subjecting it to strong impact could cause damage.

1. Outline and Features
Outline
This set allows trainees to practice a series of obstetric assistance techniques, such as protection of
the perineum and inspection of the fetus and placenta.
Features
・ The obstetric model - vulva II is made with a highly elastic and durable material that
decreases resistance and reduces the amount of force needed to extract the fetus during
delivery, enabling smooth practice.
(Use glycerin to lubricate.)
・ Protection of the perineum can be practiced.
・ Breech extraction can also be practiced as one type of emergency response.
・ The umbilical cord is soft and slides away from scissors when being cut, so that each one
can be used multiple times to practice tying and cutting. The fetal model and placenta
model can be attached to practice the entire sequence of steps from delivering the fetus to
tying the umbilical cord, cutting the umbilical cord, and delivering the placenta.
・ The placental membrane laceration part can be detached into three parts for inspection of
the placenta and checking whether or not the membrane is intact.

3. Place the hook of the placenta model on the string loop of the umbilical cord. Unfold the
edges of the ends that were rolled down so that the end of the umbilical cord of the placenta
model covers the umbilical cord.
*If the umbilical cord is not partially covered by the umbilical cord of the placenta model, they
may come apart during delivery.
*Make sure the parts are not lubricated when attaching them together, as it will be di󱐰cult
to slide the umbilical cord of the placenta model over the umbilical cord if they are lubricated
with glycerin or another lubricant during this step.
4. Roll down the end of the umbilical cord connector with a hook attached so that the hook is
visible, then attach the hook to the umbilical ring on the fetal model (LM-0633). After attaching
the hook, unfold the end.
