2.5.4 Patient Bed Interlock
For patient positioning, a patient bed is supplied with the excimer laser.
WARNING!
Risk of injury! Incorrect ablation results possible!
To prevent unintentional movements of the patient bed during the laser
ablation the patient bed should be equipped with an interlock.
If no interlock is used to block patient bed movements during ablation, be
aware of releasing the foot switch or pressing the emergency stop button if
any movements occur.
2.5.5 Laser Warning Lamp and Door Interlock
The laser provides a potential-free relay contact to switch a laser warning lamp, which may be
mounted outside the room, e.g. above the entrance door of the laser room. The lamp will
automatically switch on when the laser is operating.
Furthermore, it’s possible to connect a normally closed potential-free door contact to the laser.
The door interlock will stop laser triggering in case of opening the door during laser operation.
The door interlock is short circuit by default by means of a short circuit plug at the door interlock
input.
IMPORTANT NOTE
Be aware that a door interlock will interrupt the laser treatment every time
someone opens the door. This may disturb your treatment sequence and
therefore the treatment outcome.
SCHWIND eye-tech-solutions recommend not using the door interlock.
The clearly-defined laser area of the system tolerates absence of the interlock because there is
no direct potential risk for persons entering the operation room during laser activity.
However, in some countries national regulations are insistent that a door interlock has to be
connected.
IMPORTANT NOTE
Warning lamps and door interlock contacts are not included in the scope of
delivery of the AMARIS laser.
Please contact the SCHWIND eye-tech-solutions service department for the
electrical specifications and installation notes if you want to connect a laser
warning lamp to the laser or to use the door interlock.
