WARNINGS

Generals

• It has not been detected anomalies in the operation of the equipment by the effect of
external electromagnetic interferences, such as mobile phones, laptops, etc.

• It has not been detected any alteration in the operation of the equipment by variation

of the environmental conditions

• It has not been detected injurious effects of the equipment on the patient nor on the

operator. Despite of it, the use of protective goggles or screens is recommended.

• It has not been detected any perturbation in the water balance of the patient by effect

of the lamps of cold light.

• Monitor bilirrubin values according to the indications of the medical facultative.

• Do not use NESTOPHOT equipment in combination with flammable products, such as

cleaning or antiseptic agents

• Do not store medicaments nor infusion liquids into radiation area

• Do not use NESTOPHOT equipment in the presence of gases that can help the com-

bustion

• Do not use two or more phototherapy units together nor adjacent

• Carry the equipment holding the vertical bar. Do not push the frontal nor the back of

the lamps module to transport.

In chapters

• Bilirubin photoisomer can cause detrimental effect in the patient

I

• NESTOPHOT uses cold light lamps, so its use do not increase patient temperature

• This equipment can be used in combination with a therm otherapy device, without af-

fecting the temperatur e of the patient. So, the use of skin temperature sensor is not
indispensable.

- Cover infant's eyes to protect from high light levels.

II

- The fluorescence lamps must be collected according the current legislation.

V

- The substitution of the lamps must be made only by authorized qualified personnel.

- The use of lamps others than recommended (DULUX ® L lamps) can affect both the

security and the effectiveness of the equipment.

I. PRELIMINARY

Intended use

Bilirrubin is produced primarily in the decomposition of red blood cells; it becomes water-solubles
in the liver through combination with glucuronic acid and thus be separated (through the bile).

If an icterus occurs on the first day of the newborn infant, treatm ent to reduce the bilirubin is nec­essary. The phototherapy method has predominated as a reliable method. Through a photo­chemical reaction, light changes insoluble bilirubin into the water-soluble form, permitting removal
through the bile and urine without coupling to the glucuronic acids in the liver. For an effective
treatment at least 4 ìW/cm

NOTE : bilirubin photoisomer can cause detrimental effect in the patient

2

/nm of radiant flux is required.

NESTOPHOT phototherapy unit em its 8 ìW/cm

2

/nm exactly in 460 nm range to re duce the treat­ment duration and, consequently, increase lamps life. This turns it to an extremely suitable instru­ment for bilirubin treatment

NOTE: NESTOPHOT uses cold light lamps, so its use do not increase patient tem­perature

NESTOPHOT equipment is provided with an electric clock for total operation time and an electric
clock for treatment time with zero reset. NESTOPHOT has four castors to its better mobility.

NOTE : this equipment can be used in combination with a thermotherapy device, with­out affecting the temperature of the patient. So, the use of sk in temperature sensor is
not indispensable.
