A1 ACOUSTIC RHINOMETER SAFETY INFORMATION
Read this Operating Manual before attempting to use the
Instrument.
WARNINGS
This instrument is for indoor use only and it should be used as described in this manual.
The system must not be used in the presence of flammable gases or in an environment
which is susceptible to explosions - beware of oxygen, dust, and anaesthetic gases.
To avoid risk of electric shock this equipment must be connected to a mains supply with a
protective earth.
If your desktop PC or printer does not have a power supply approved for a patient
environment, then an isolation transformer, which complies with BS EN 60601, should be
used to power the PC, printer, and the A1 Acoustic Rhinometer. You must use the isolation
transformer to ensure that the A1 Acoustic Rhinometer is in compliance with BS EN 60601.
As this is a mains-powered, PC-connected product it is advisable to not touch the patient
while using the equipment.
The equipment should be positioned in such a way that it can be easily disconnected from
the mains supply. The operation of the system can be safely terminated by switching off the
device or removing the mains plug.
The applied part is the nosepiece, which is marked for single use. It should not be re-used,
as no method of sterilisation can be guaranteed - disinfection materials may not be effective
and may leave a residue, which could be harmful.
CAUTIONS
The nosepieces are made of a material, which may cause an irritation reaction in some
patients. Use of the nosepieces should be discontinued in patients who exhibit such a
reaction.
Nosepieces are a single-use item. Single-use items should not be reused as they could
transfer infections between subjects.
Federal (USA) law restricts this device to sale by or on the order of a physician.
The use of an A1 Acoustic Rhinometer near to sources of electromagnetic radiation, such as
mobile phones, radio transmitters, x-ray equipment etc., may prevent it from functioning
correctly.
