How to wear the oral interface correctly?

How to start the device?

How to reach Negative Air Pressure?

When your oral interface is in the right position, it takes 10-15 seconds to reach vacuum in your oral cavity, it pulls the tongue toward upper palate and also pulls the soft palate forward.

Tips of reaching Vacuum:

1. Swallow Saliva.

2. Sucking the tube (as if you’re using a straw)

3. Stick your tongue to upper palate and forwarded position.

To improve SEALING: Swallowing can help maintain the seal during the night. Making the humming sound can help.

In the first month, sealing percentage average is 60% – 70%, While continuing to acclimate during months 2-3, this percentage is likely to improve to 85% – 99%.

Note: Above is an average, each person might have different result base on his/her obstructive level.

iNAP Daily Maintenance

Step 1: Oral Interface and Tubing

Keeping the tubing connected to the oral interface, let cold water flow through the oral interface and through the tubing and then have water flow from the grey tubing end and through the oral interface. This process should last around 30 seconds.

Step 2: Container

Remove the dry pad, throw in the trash, and rinse both the container and the lid in cold running water. Be sure that no saliva remains within any part of the lid.


1. Place the Oral Interface and Tubing High and Low:

Under the faucet, hold one end of the tubing higher than the other end, letting the water run through the low end.

2. Swing the tubing:

Once clean, take one end of the tubing and swing it around to spin out the water inside the tube; grab another end and do the same.

iNAP Weekly Cleaning

1. Connect the oral interface, tubing, container, and the iNAP console. 2. Prepare a cup with 8 oz of lukewarm water. note: DO NOT use hot water higher than 40 °C/ 104 °F.
3. Place the oral interface inside the cup.
4. Drop a Potassium-peroxymonosulfate-based cleaning tablet into water and ensure the cleaning tablet begins to dissolve.
5. Set timer for 15 minutes to disinfect the oral interface. note: DO NOT soak your oral interface, tubing, and saliva container in the cleaning solution overnight. Prolonged immersion might cause damage to the filter.
6.Lay the iNAP console down on the counter. Be sure that the lid is on tight and turn the iNAP on. The battery power light will be solid green, and the vacuum status light will be flash blue. The negative pressure will draw the cleaning solution into tubing and saliva container.
7. When the container is full, the orange light will be solid, and the vacuum status light will become dim. Turn off the iNAP console, wait 15 minutes to disinfect the saliva container, oral interface, and tubing.
8. Remove all the cleaning solution and clean the oral interface, tubing, and container with running water.
9. Let the components air dry. Note: If you feel the smell of the cleaning tablet particles on the oral interface, soak the oral interface in warm water for 10 minutes before using.
