4 Safety Instructions

National regulations for installation, startup and operation of medical products

(respectively medical illumination) have to be considered in addition to the

instructions given in this manual.

The UV-X device is an active medical device of class IIa according to European

Medical device directive 93/42/EEC.

Any LED system can cause physical harm if used improperly. The UV-X is a LED

product class 3R (EN 60825-1). Created UV-light leaves the housing of the

device at the designated aperture.

During operation of the device the so called “LED area” must be delineated and

identified accordingly (EN 60825-1), similar to requirements for a powerful

medical laser.

Protective goggles must be worn in case of peripheral light emission in the

treatment room.

Always keep the beam aperture covered with the UV-sensor before and after

each treatment. System tests should not be started without a properly mounted

sensor.

Remember that reflective materials can deflect the UV-light in unexpected

directions. Special attention must be paid to mirrors and glass surfaces. Similarly,

high-gloss polished metal surfaces within a few meters of the device can cause

dangerous irradiation.

Except for the therapeutic application, never look directly into the light beam or

aperture.

If the light beam is deployed for medical purposes, the user is responsible for

assuring that all optical devices used for observation or adjustment are outfitted

with appropriate protective filters.

All system components such as the light source, wall power supply, DC cable

with plug, UV light meter and stand should be checked prior to each treatment.

Do not use the UV-X system if any signs of damage of the equipment are

observed.

The UV light meter has to be calibrated every 12 months by IROC.

The system should undergo routine inspection and maintenance per

manufacturer’s recommendations and institutional standards.

Eye protection

4.1

CAUTION – The UV-X system is a high-power LED product; it underlies

the EN 60825-1 for laser and LED devices. It is emitting UV-light at 365

nm.

CAUTION – The UV-X system is a Class 3R LED product. Avoid direct

exposure to the beam.

CAUTION - Never look directly into the UV light beam. Never direct the

beam towards a person except for therapeutic purposes.

Due to the irradiance levels involved, the eye is particularly at risk of injury from

direct exposure to the high-power LED beams. The protection concept against

LED radiation has two components:

•

Proper operation of the LED device by the physician to protect the

patient

•

Use of safety goggles to protect involved persons, including the

physician, from unintended beam emissions

Protective safety goggles for use with UV-X LED system must meet the

following minimum specifications:

D 365 nm L1 (according to EN 207:1998 + A1:2002)

2-1.2 (according to EN 170:2002)

For the purpose of safety verification, the protective goggles must be marked as

indicated above.

distract the attention of the patient. The patient should lay on a bed or patient’s

chair. The head should rest comfortably in a headrest. It is imperative that the

patient chair or the system not be moved during the treatment procedure.

Treatments with inaccurate photosensitizer and/or UV light dosage may be

ineffective or cause significant harm to the patient’s eye. Possible damages may

include:

11/62

•

Irreversible light damage to the retina or other intraocular structures

(Causes: No riboflavin and normal UV-light dose)

•

Irreversible endothelium cell damage (Cause: High UV-light dosage with

low riboflavin dosage)

•

Safety design

4.4

General specifications and standards relevant to design and manufacturing

practices and procedures, such as those delineated in standards EN 60601ff and

EN 60825-1 were adhered to in the design and manufacture of the UV-X

illumination system. The following protective measures are integrated in the

system to achieve a high degree of safety and operating comfort.

The device is controlled by an internal microprocessor. This processor is

checked for proper working functions. In case of processor failure, no UV light will

be emitted due to the design of the device.

The microprocessor unit controls the electrical current used to drive the UV-LEDs.

This design allows the required UV light emission to remain constant and to

detect defective LEDs.

A red status display light indicates internal errors of the device. UV emission is

locked in such cases.

The user is actively involved with the testing of the irradiance level and should

record the test results. If test results are not within the permitted tolerance levels,

treatments must not be performed.

WARNING - System must be mounted and aligned to the patient eye by

the user.

Unsafe mounting or fixation of the system may cause physical harm to

the patient!
