The MedRx Video Otoscope represents a new era of otoscopic examination in your office. The clear resolution of the MedRx Video Otoscope is particularly helpful when comparing a clean ear canal with normal eardrum to a canal that has excessive cerumen, foreign bodies, external otitis, PE Tube status, cholesteatoma, TM perforations or other abnormalities.

Getting to Know Your Video Otoscope

Intended Use Statement:
The MedRx Video Otoscope is used to perform otoscopic examination of the outer ear and tympanic membrane. The MedRx Video Otoscope is an endoscope designed to perform video otoscopic evaluations. It is also used to assist with hearing aid and probe microphone placement for Real Ear Measurements. These devices are to be operated by professionals with education and/or training in the field of audiometry. The device consists of an Otoscope connected to a video camera that can present the image on a video screen. This function gives you the option to capture images for storage.

Indication for Use Statement:
The MedRx Video Otoscope is for use by professionals with education and/or training in the field of audiometry to provide detailed examinations of the outer ear canal and tympanic membrane. The MedRx Video Otoscope is an endoscope designed to perform video otoscopic evaluations. Also used to assist the hearing aid and probe mic placement for Real Ear Measurements. The image provided by the camera can be captured and stored as a visual record of the examination.

Video Otoscopy has multiple purposes in hearing assessment and hearing instrument fitting.

The Video Otoscope is used for:

• Performing the initial otoscopic examination prior to testing.
• Capturing and storing images to the Noah patient database.
• Troubleshooting problems with the hearing aid, such as blocked receivers and microphones.
• Probe microphone placement for Live Speech Mapping or Real Ear Measurements.

Always perform an otoscopic examination of the ear canal prior to testing to determine if earwax or other foreign matter will interfere with inserts and probe tube insertion. If this is a problem, the patient should be referred to an appropriate resource for removal of the wax or debris. If abnormal ear conditions are noticed on this examination, an appropriate medical referral is recommended before evaluating hearing or fitting hearing instruments.
The speculum is always to be used with the system. Remove the speculum and use an alcohol pad to clean the video otoscope lens. The speculum must be cleaned or replaced between patients per accepted medical practice procedures. (Reference section: “Cleaning and Disinfecting” for more information)

CAUTION: The MedRx Video Otoscope is only to be used by a person qualified in the use of an Otoscope. Misuse can cause a patient pain and possible injury.

This manual will familiarize you with the features and software for the MedRx Video Otoscope system.

Cleaning & Disinfecting

Your MedRx Video Otoscope has been designed to provide years of trouble-free service. Do not remove or open the camera housing, as there are no user serviceable components inside.

Cleaning
To keep your system looking new, wipe the exterior of the components with a soft cloth. Stubborn stains may be removed using a cloth moistened with water and mild detergent. Do not allow debris or fluid to enter into the components. Remove the speculum and use an alcohol pad to clean the lens on the end of the Otoscope probe, or a common disinfectant.

Video Otoscope Disinfecting
The Video Otoscope is sealed so that it may be wiped between patients with the following surface cleaners to disinfect; 70% Alcohol, Chlorhexiderm, Cidex, Nolvasan, Parvocide, Parvoso, Roccal or Synphenol. Follow instructions provided with the disinfectant.
The scope should NEVER be heat sterilized, gas sterilized or soaked in liquid because damage may result.

Speculum Replacement
The speculum is always to be replaced between patients.

Transportation & Storage

When transporting or storing your Video Otoscope, it is best to use the original packing case or similar packaging. Store the system in a cool, dry location and do not place your system in direct sunlight. Care must be taken to protect the system from shock, moisture damage and mishandling. Do not place heavy objects on any of the system’s components. To assure proper operation and warranty protection, use manufacturer’s replacement components only.

EMC Precautions

The MedRx Video Otoscope needs special precautions regarding EMC and needs to be installed and put into service according to the following EMC information.
List of all cables and maximum lengths of cables, transducers and accessories:

Transducer / Accessories
USB Cable

Maximum Cable length
2.6 meters

Warnings!

• The use of accessories, transducers and cables other than those specified, with the exception of transducers and cables sold by the manufacturer of the MedRx Video Otoscope as replacement parts for internal components, may result in increased emissions or decreased immunity of the MedRx Video Otoscope.
• The MedRx Video Otoscope should not be used adjacent to or stacked with other equipment and if adjacent or stacked use is necessary, the MedRx Video Otoscope should be observed to verify normal operation in the configuration in which it will be used.
• The MedRx Video Otoscope may be interfered with by other equipment, even if that other equipment complies with CISPR emission requirements.
• The MedRx Video Otoscope does not have life supporting function
• Portable and mobile RF communications equipment can affect the MedRx Video Otoscope.
• WARNING: Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of the MedRx Video Otoscope, including cables specified by the manufacturer. Otherwise, degradation of the performance of this equipment could result.”

a          Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the MedRx Video Otoscope is used exceeds the applicable RF compliance level above, the MedRx Video Otoscope should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the MedRx Video Otoscope .

b         Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
