MCO25plus Operating Instructions
2.4
Protecting the Patient
The patient must be protected against injuries caused by improper use of the laser system. In
particular, this means
•
protecting the patient's eyes with suitable antilaser goggles or by using a light- and
radiation-proof cover;
•
protecting those organs and tissues of the surgical site which may not be exposed to laser
radiation, using diffuse-reflection or radiation-absorbing materials such as moist towels or
compresses;
•
prevention of laser-induced fires (see section 2.3), especially in endolaryngeal
interventions;
•
effective removal (evacuation) of developing toxic smoke, particularly in the laryngeal
region;
•
preventing the ignition of easily flammable intestinal gases during rectoscopic
interventions;
•
preventing fires caused by direct laser radiation when using artificial respiration techniques
such as jet ventilation, particularly in connection with easily flammable, oxidizing gases.
2.5
Treatment Room Requirements
•
All rooms in which the MCO25plus is used must be marked at the entryways/doors with a
laser radiation warning sign (see "laser star" symbol provided in the accessories kit).
•
A warning lamp must be installed at all doors leading to the laser area. When these lamps
are on, the laser area may only be entered by authorized persons wearing appropriate
protective goggles.
•
As far as possible, all doors leading to the laser area should be kept shut while the laser
system is being used.
•
All surfaces reflecting the CO
or adequately covered.
2.6
Safety Requirements for the Laser Unit and its Accessories
•
All instruments used should have matte surfaces guaranteeing diffuse reflection of the CO
laser light.
•
All optical equipment used for observing the surgical field must have been specially
designed for use with laser systems. Besides, such equipment may only be used in
connection with suitable auxiliary filters that meet the requirements for laser protective
goggles.
•
Never switch on the laser system unless all parts of the housing have been properly fixed
in place. Be aware that uncontrolled laser radiation may escape as long as the laser unit is
open! Moreover, an open housing poses a hazard of coming into contact with dangerously
high electric voltages or current.
V 4.1
