Using the Included Power Adaptor Ensure the work area is clean and dry. Place the trainer on a stable, flat surface. Before first use select the appropriate plug fixing for your local mains supply from those included. Insert the plug fixing into the adaptor with the large catch at the base of the adaptor. Align the small rectangular groove on the top of the fixing and press this into the adaptor so that it clicks into the spring lug. Plug the low voltage cable from the adaptor into the power jack at the rear of the simulator. The simulator is now ready for use. Removing the Shoulder Base The...

Power on and Select Conditions 3a Power on the model using the power switch. The green indicator light on the switch will illuminate. If the model fails to power on, check the batteries are fitted correctly and have sufficient power, or check the low voltage cable is attached correctly and the mains supply is turned on. After a short delay, the ear LED condition number indicator will display a “1”, indicating that Condition 1 is being displayed in the ear. Whenever the model is powered off and then on again, the ear condition will automatically default to Condition 1. To set a condition, simply...

Otoscope Use and Flexible Pinna 5a An otoscope (not included) may be used to view each condition - insert the speculum into the ear canal with care. The flexible pinna may be manipulated to straighten the ear canal. Treat the ear with the same care you would a patient. Excess force may cause damage to the model. For best clarity of display of the conditions, we recommend setting the otoscope light to “off”. Sleep Mode The model has an automatic sleep mode which turns off all displays to conserve power. This is functional if either battery power or mains power is used. During sleep mode, the last...

If battery power is insufficient for the model to function correctly, low battery indication may display. The green power indicator light will illuminate when the model is powered on however the LED condition number indicator display and main condition display will remain off. Switch the model off and replace the batteries. Do not power down and leave or store the trainer with batteries installed for prolonged periods. Always remove batteries before storage. Using the Supplied Rigid Carrying Case 8a After use, or before transportation, the model should be placed with the head installed in the...

by Professor Tony Wright, Emeritus Professor of Otolaryngology “Figure 1 is a normal, adult right tympanic membrane viewed with a wide angle telescope. The handle of the malleus (blue arrow) runs from the lateral process at the top to the umbo in the middle of the membrane – the pars tensa. Posterior, i.e. to the left as you look at the image, is the long process of the incus (red arrow). Above the white bump at the top of the malleus handle - the lateral process of the malleus - is the so called attic region of the ear drum - the pars flaccida (green arrow).” “In Figure 2, I have removed the...

Chorda Tympani Long Process of the Incus Malleus Round window

by Professor Tony Wright, Emeritus Professor of Otolaryngology Condition 1 NORMAL I The main clinical features are: • This a normal right tympanic membrane The handle of the malleus runs from the lateral process at the top to the umbo in the middle of the membrane – the pars tensa Posterior, i.e. to the left as you view the image, is the long process of the incus Above the white bump at the top of the malleus handle – the lateral process of the malleus - is the so called attic region of the ear drum - the pars flaccida Comment: The bright spot in front of and below the malleus is a reflection...

EAR WAX (CERUMEN) The main clinical features are: • The very thin skin of the deep ear canal grows and migrates outward from the eardrum to the opening of the canal. This normally keeps the ear canal free of debris and maintains the resonance properties of the canal helping clarity and volume of hearing • Close to the outside of the canal are modified sweat glands that produce a liquid with anti bacterial and anti fungal properties • Further out are the fine hairs that produce a waterproof oily material Comment: The combination of skin, sweat and oil forms a thin film of “wax” which protects...
