14. Obstetric Assistant Model Handling Precautions
14-1. 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 sufficient 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 models or placing them 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 following use, 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 affected,
please consider ordering a replacement.
10. Air bubbles or impressions in the models that may remain from the fabrication process do
not affect the strength of the material, as the material used is highly tear-resistant.
11. This model is washable. After washing, wipe off 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.)
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.
