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.

This model is manufactured to feel to the touch like a living human body. Forceful or careless handling
may damage the model.

2. Under no circumstances must the specially provided tracheal cannula be used on the living

human body.
3. Do not leave the specially provided tracheal cannula attached to the trachea for a long period, as
this may accelerate hardening of the cuff, making it unusable. Detach the tracheal cannula from thetrachea after using the model.
4. Inspect the condition of the cuff before use, since the specially provided tracheal cannula hardens withrepeated use. If hardening of the cuff makes it difficult to use, please consider obtaining a new special
tracheal cannula for this model, available for separate purchase.
5. Insert the specially provided tracheal cannula using water-soluble lubricating jelly containing glycerol
as the main constituent (“K-Y Lubricating Jelly” is recommended). Do not use oil lubricants (e.g., olive
oil, Vaseline), alcoholic lubricants, or other lubricants containing organic solvents, as these may cause
damage to the cuff.
6. 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.
7. Use water to practice cleaning or disinfecting the area surrounding the tracheostomy orifice. The useof alcohol or disinfectant may cause deterioration of the neck surface skin.
8. Be careful not to lose the neck surface skin holding plate, as it is not fixed to the model.
9. Be careful to prevent the simulated sputum provided as an accessory from contacting with a living
human body (e.g., eyes, mouth). (The simulated sputum is made of cosmetic materials listed in theJapanese Standards of Cosmetic Ingredients and the Japanese Cosmetic Ingredients Codex.)
10. Oily fluid may exude from the neck surface skin. Do not leave the neck surface skin attached to themain body after using the model. Wrap the neck surface skin in a paper towel or piece of gauze andstore it in the specially provided plastic zipper bag.
11. Do not place any object on the main body, as doing so may change the model’s shape.
12. Store the model in a place where it will not be exposed to direct sunlight or UV.
13. Tube Feeding Components (LM-097C) cannot be attached to this model.
14. This product is intended for use in standard operating environments. Do not use it in heavy industrial
settings.
15. 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 beforestoring. The company will not be involved with or held liable for pest damage that occurs during 		storage.

1. Outline and Features
OutlineThis model can be used to practice the procedures carried out for tracheostomy patients inthe fields of nursing and caregiving when replacing cannulas or performing suction through acannula. The model can be divided into two halves and the trachea component is transparent,
allowing confirmation of the condition of cannula insertion status and the position of thesuction catheter in the cannula during suction. In addition, with the specially provided cannula
attached, a ventilator can be operated by connecting a test lung (simulated lung) to the model.

Features・ Allows the user to practice the procedures for replacing cannulas.
・ As the trachea section is transparent, the state of inflation of the cuff can be observed,
and by using the specially provided cannula, the approximate optimum pressure canbe confirmed. (Because the posterior wall of the trachea is soft, the user can feel thecompression of the trachea that results when the cuff is overinflated.)
・ The transparent trachea facilitates explanation of how the suction catheter should bepositioned, and of how to perform suction using the upper part of the cuff. (The above
mentioned practicing of suction procedures can be performed using the simulated sputum.)・ The soft neck surface skin allows the user to feel the thyroid cartilage through the surface
skin.
・ The detachable trachea section facilitates explanation of the areas where granulation tendsto develop.
・ A ventilator can be operated by attaching the specially provided cannula and connecting atest lung, allowing confirmation of the alarm tone generated when air leakage occurs.

3. Handling the Model
3-1. Assembling the Model① Take the neck surface skin out of the paper wrapping, align the hook and loop fasteners witheach other, and attach the neck surface skin to the model.

② Apply water-soluble lubricating jelly (K-Y Lubricating Jelly is recommended) to the tip of thespecially provided tracheal cannula, and insert the cannula into the model.

③ Operate the cuff of the specially provided tracheal cannula so as to achieve the optimumpressure [20–33 hPa (20–34 cmH2O, 15–25 mmHg)] as indicated by the blue line locatedbetween the two red lines (“Hi” and “Lo”)Blueon linethe(Pressurecuff pressurein the cuﬀ)indicator. In addition, thepressure in the cuff can be measured using the cuff pressure gauge while air is being injected.

3-2. Observing condition of insertion of the Tracheal Cannula and Cuff
① Hold the tag and peel open the neck surface skin.

② Detach the side of face from the main body. When doing so, pull away the side of facegradually, and do not use excessive force, as this might rip off the hook and loop fasteners.

③ Put the neck surface skin holding plate on the neck of the main body, and place the necksurface skin on the plate. Be careful not to lose the neck surface skin holding plate, as it is not

*When explaining granulation, indicate the relevant area with the trachea arranged as shown.
For greater clarity, indicate the areas of granulation using commercially available stickers etc.

② The trachea has lines indicating the positions for attachment of the trachea cap and forattachment of test lungs designed to be connected over the trachea. Attach the test lungover the trachea by pushing on the lung up to the line indicating the relevant position. Test
lungs designed for insertion inside the trachea should be pushed in deeply and firmly.

3-4. Detaching Components① Remove the specially provided tracheal cannula.
② Detach the neck surface skin from the model in the same manner as in 3-2 ①③ Remove the trachea.

4. Caring for the Model
1. If stained with lubricant, rinse out the neck surface skin, trachea, and specially provided
tracheal cannula with water.
2. Oily fluid may exude from the neck surface skin. After using the model, do not leave the necksurface skin attached to the main body. Wrap the skin in a paper towel or piece of gauze, andstore in the plastic zipper bag provided as an accessory.
3. If the neck surface skin becomes sticky, apply baby powder.
4. Stains on the model should be wiped with moist gauze or similar material using water or aneutral solvent diluted with water.
* Do not use thinner, benzene or similar solvents.
5. After using the model, remove the specially provided tracheal cannula from the trachea, andstore it separately. If it remains attached to the trachea for a long period, the cuff will harden
and become unusable.

85. How to Attach the Optional Bronchus (sold separately)
The bronchus (LM-097D) and bronchus clasp (LM-097A) for Suction Training Model Type II can be
attached to the KOKEN Tracheostomy Management Simulator.
① Remove the trachea cap in the same manner as in 3-3 ① .
② Attach the bronchus clasp to the bronchus for Suction Training Model Type II.

③ Next, push the bronchus onto the trachea up to the position for attachment of the tracheacap, and fasten the bronchus clasp.
