should only be used as an additional assessment method. Under no circumstances can or should
invasive surgery or measures that put the patient at risk be carried out based on the measurement
results alone.
■ In the case of malfunctions and/or defects being suspected and/or ascertained, the device has to be
taken out of use immediately, labelled as 'Out of Use', and secured to prevent use. Please contact the
manufacturer or your sales partner immediately under all circumstances.
■ The measurement system has to be checked to ensure the measurement function is operating
correctly at regular intervals. For further information about this, please see the 'Functional checks
and preparation' chapter in this handbook.
■ Do not install the jaw motion analysis system near a source of heat or in direct sunlight behind a
window, as excessive heating can lead to incorrect measurement results.
■ Ensure that all power and connection cables are routed and protected so that nobody is able to trip
over them. Check all cables and connection plugs regularly for damage. Damaged power supply
units, plug connectors and cables must be replaced before further use.
■ The measurement system is not protected against the penetration of fluids. If fluid penetrates the
measurement system, switch it off and please contact the SICAT GmbH & Co. KG technical service
team.
■ Never introduce objects into components of the measurement system.
■ Before starting every measurement, it is necessary to ensure the correct choice and correct position
of the transmitters or application aids. The cables or the application aids (e.g. feeler) can present a
risk of injury to the patient. In this context, please consult the special instructions in the handbooks
of the application software, and do not allow children or mentally impaired patients to enter the
proximity of the device without supervision.
SAFETY INFORMATION ON HEART PACEMAKERS / DEFIBRILLATORS
■ In the magnetic coupling for the attachment of the lower jaw (LJ) sensor on the T-attachment there
are strong permanent magnets, such as those that are used on headphones on MP3 players. Under
especially unfavorable circumstances, at short distances (< 15 cm), these magnets can have a
negative impact on the functionality of certain implanted heart pacemakers and defibrillators.
Therefore, the LJ-sensor should not be positioned on the upper body of the patient on patients with
electronic implants.
■ Version BT devices contain a Bluetooth transmitter as an interface to the PC. Although there is so far
no evidence of a possible interference of heart pacemakers/defibrillators by Bluetooth transmitters,
the SICAT JMT+ system is not recommended to be used on patients with electronic implants using
the neck strap, but with the maintaining of a safety distance of at least 15 cm from the patient's
thorax.
■ No interference of electronic implants is to be expected from the ultrasonic transmitters used in the
measurement system, as the SICAT JMT
+
system works with airborne sound and a very low sound
power of a few milliwatts. Due to the adverse connection during the transition from the air into the
human body, the noise intensity of the measurement signals is weakened strongly such that any
interference with implants, as well as any damage to tissue, is excluded.
