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. These models are made with a special material to simulate the texture of human skin. Pleasehandle these models with the same care that you would exercise when working with a humanbody. Pulling the models with excessive force or subjecting them to a strong impact, such as
dropping them, may cause damage.
2. The material of the models has a distinct odor, which fades with time. This odor is not harmful tothe human body and does not indicate poor quality. There may also be a smell of baby powder
remaining on the product, as baby powder is applied to the models during fabrication.
3. Wear disposable gloves when using the models.
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. 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.
6. 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.
7. Do not use oil-based inks, pencil, chalk, or paints on the model as they will soak into the materialand cannot be removed.
8. Placing objects directly on top of the models or placing them on uneven surfaces may cause
deformation.
9. After washing the models, or if the surface of the models becomes sticky following use, apply
baby powder all over the models to reduce friction.
10. The models may lose their shape after a long time. Check the shape of the model about 3 years
after purchase. If a model is deformed to the extent that its functioning is affected, consider
replacing it.
11. Air bubbles or impressions in the models that may remain from the fabrication process do notaffect the strength of the material, as the material used is highly tear-resistant.
12. Use a 14 Fr gauge or smaller urinary catheter. Be sure to apply lubricant (glycerin) before use.

Handling and Safety Precautions
These precautions should be strictly observed in order to ensure safe,
long-term use of the product.
Caring for the model after use
1. To clean smudges or marks on the model, wipe with a moist cloth, gauze or similar material using
water or a neutral solvent diluted with water. Wipe off all the remaining water to prevent themetal parts from rusting. If the metal parts become rusted to the extent that their functioning isaffected, consider replacing them. After wiping off the smudges or marks, apply baby powder
all over the models. (Do not clean the model with rubbing alcohol, thinners, benzine or otherorganic solvents.)
2. Storing the models for an extended time in a high or low temperature environment may cause
deformation. Exposure to direct sunlight or UV rays may also cause the material to deteriorate oralter its shape or color. Store the models in a 0-50°C environment, in a place where they will not
be exposed to direct sunlight or UV rays.
3. Oil may leak from the models. When storing them, wrap them in paper towel, gauze or anothercloth, and place them in the re-sealable plastic bag that comes with the kit.
4. The uterus dilation models and fully dilated model can be washed normally. After washing, wipe
off all the remaining water with a soft, dry gauze or cloth.

1. Outline and Features
OutlineThis model is made with a new material that stretches well and is tear-resistant, for more durability
than the previous model and better simulation of the texture of human skin. It attaches to thefollowing products.

Features
1. Bishop scores from the late stage of pregnancy to the onset of labor (cervical dilation,effacement, consistency and position) can be confirmed.
2. Made with a material that is more tear-resistant than the previous model, increasing its
durability.
3. The mucous membrane of the vaginal cavity is made with a new material that simulates the
texture of the human vaginal cavity.
4. The vaginal walls give a sensation of clinging to the fingers.
5. The excess constriction on the fingers felt when using the previous model has been reduced
to enable practice with a feeling that closer simulates that of the human body.
6. Gives a more realistic feel of the ischial spines and pubic symphysis during vaginal
examination. (When used on the main body.)
7. Three models with varying degrees of uterine opening dilation are provided, along witha model of the fetal head. These can be interchanged and the degree of engagement canbe adjusted, making it possible to gauge the progression of labor by means of vaginal
examination.
8. The fetal head model can be used to gauge rotation of the fetal head by varying positionsof the sagittal sutures and posterior fontanel.
9. The vulva has a urethral orifice for inserting a urinary catheter.
*2-6 are comparisons with previous Koken models.
