Safety Information

Intended Use

The N9+ (OTC) device, combined with a smartphone application (Nonagon Care Kit), is a multiple-sensor device that is intended to measure, record, and transmit the recorded data of auscultation sound, body temperature, oxygen saturation (SpO2) and pulse rate, and images of an examined body part.
The Nonagon Care Kit is intended for use by adult lay users in a non-clinical environment. The Nonagon application enables counseling with the physician and transmission of the information over an IP network. The oxygen saturation (SpO2) sensor of the device is for Rx only.

Exam Specific Precautions

Oximeter Exam:

  • Inadequate peripheral perfusion may preclude measurement of oxygen saturation or lead to inaccurate measurement.
  • Do not press the finger down too hard, and keep your finger still.
  • Make sure the sensor is covered and no light from the sensor is visible.

Ears Exam:

  • After checking one ear, remove the speculum, and place a clean speculum on the otoscope before checking the second ear.
  • Do not use the otoscope if you suspect there is a foreign body in the ear. Consult your doctor.
  • Children under the age of 6 months should only be examined by a healthcare professional. Do not use the otoscope on children under the age of 6 months.
  • For children between 6 and 24 months, it is recommended to perform the ear exam with the guidance of a healthcare professional (telehealth or your physician ) and to start with the toddler-size speculum.
  • For patients above 24 months, it is recommended to start the exam with the adult speculum.
  • Always use a speculum. Do not insert the wireless otoscope tip into the ear canal.
  • Perform the otoscope examination carefully so as not to harm the inner parts of the ear.
  • The wireless otoscope is equipped with a built-in rechargeable battery, do not throw away the charging cable.
  • Do not knock or drop the otoscope. In case of product damage due to collision or falling, stop use.
  • Do not use while moving and protect from being hit by passersby while using the otoscope.

Thermometer Exam:

  • Clear forehead measurement area from hair and make sure it is dry before taking temperature measurement.
  • Make sure the thermometer sensor is touching the area between the eyebrows and the diaphragm is also touching the forehead.
  • This thermometer is not intended to interpret hypothermic temperatures.
  • Intended for patients aged 2 years old and up.
  • Even in the absence of fever, those who exhibit a normal temperature may still need to receive medical attention. People who are on medication should not be assessed solely on temperature readings to determine the severity of their illness. Use of the thermometer is not intended as a substitute for consultation with your physician.

Stethoscope Exam:

  • Use of the stethoscope in patients under 6 months is not recommended.
  • Heart, Lungs and Abdomen exams should be performed on a patient’s bare skin.
  • Make sure the diaphragm is firmly in place.
  • Perform the exam in a quiet room. Noises may interfere with the quality of the recording.

Mouth and Throat Exam:

  • Avoid hitting the teeth when using the tongue depressor.
  • In particular, be very careful if the teeth are loose or weak.
  • Do not rub the tongue depressor against the tongue so as not to damage the tongue.
  • Do not use the tongue depressor on small children after a meal or while lying down, so as not to cause a gag reflex, which could lead to choking or vomiting.
Note: When performing the mouth and throat exam, always use the tongue depressor- to cover the tip of the otoscope before inserting it into the mouth and throat.
