1 Product Description

The neoBLUE® Phototherapy System consists of two products – the neoBLUE LED
Phototherapy light source (light) and the neoBLUE LED Phototherapy roll stand.

Intended Use

The neoBLUE LED Phototherapy System is intended for the treatment of
neonatal hyperbilirubinemia. The light can be used for infants in a bassinet,
incubator, open bed, or radiant warmer.

Important! Before assembling the neoBLUE light and administering

phototherapy, read all sections of this manual carefully. There are safety
considerations that should be read and understood before use.

Physical Characteristics

The neoBLUE LED Phototherapy System is a floor-standing, mobile
phototherapy light that delivers a narrow band of high-intensity blue light via
blue light emitting diodes (LEDs) to provide treatment for neonatal
hyperbilirubinemia.

Light Source

The light consists of a lightweight plastic light enclosure. When used with the
neoBLUE roll stand, the light can be tilted and adjusted both horizontally and
vertically on the roll stand assembly. The light enclosure can be tilted to
approximately 40° up from horizontal (the resting position). The light
enclosure height can be adjusted vertically along the roll stand post, as well
as horizontally out from the roll stand post (proximity adjustment) to aid in
positioning the light. To help position the light over the infant, a red target light
can be briefly illuminated using the right rocker switch on the front panel. The
light can be used for infants in a bassinet, incubator, open bed, or radiant
warmer.

The light can be used independently of the roll stand. The light enclosure can
be placed directly on an incubator with a flat-topped surface.

Important! Medical electrical equipment needs special precautions
regarding EMC and needs to be installed and put into service according to
the EMC information provided in this document.

placed on flat surfaces only. Confirm all rubber feet are fully seated on the top
of the enclosure to prevent slippage. When placing light enclosure directly on
incubator, care must be taken to ensure a safe operating environment.
Secure power cord to minimize risk of tripping.

Warning! Placement directly on incubator: The use of skin-

controlled mode (patient servo) of the incubator or radiant warmer is

PN 001364 Rev. I

recommended unless manual mode (air servo) is specifically prescribed.
While both modes require patient monitoring, manual mode requires constant
attention. In manual mode, care must be taken to observe any changes in
ambient conditions (drafts, sunlight, phototherapy light usage, etc) as small
changes can have an effect on patient temperature. While patient servo also
requires attention, the radiant warmer is designed to keep the patient’s skin
temperature controlled, reducing (but not eliminating) the need to monitor the
patient. In addition, use of reflective foils may cause hazardous body
temperatures. Monitor the infant’s skin temperature per your hospital policy
during phototherapy to avoid fluctuations in body temperature.

Warning! Use with Radiant Warmer: Do not place the neoBLUE

light directly under radiant heat source.

There are two intensity settings, high and low. The desired setting is selected
using the left rocker switch on the front panel of the light. The light output was
factory calibrated with the neoBLUE
intensity of 35 µW/cm

/nm at the high setting and 15 µW/cm2/nm at the low

®

Radiometer to provide an initial

setting at a distance of 12 inches (30.5 cm) from the light enclosure to the
baby. The light output can also be adjusted using the two potentiometers
(located on the side of the light enclosure) to accommodate different
distances. A lens panel protects the light from incidental debris or fluid
exposure. Blue LEDs emit light in the range of 400 – 550 nm (peak
wavelength 450-470 nm). This range corresponds to the spectral absorption
of light by bilirubin, and is thus considered to be the most effective for the
degradation of bilirubin. Blue LEDs do not emit energy in the ultraviolet (UV)
region of the spectrum, so there is no UV exposure to the infant. In addition,
blue LEDs do not emit energy in the infrared (IR) region of the spectrum,
minimizing concern about excessive warming of the infant. As with all
phototherapy lights, protective eyeshades must be used to protect the infant’s
eyes from excessive light exposure.

Warning! Eye Protection: Do not look directly into the LEDs. During

treatment, always protect the baby’s eyes with eye patches or equivalent.
Periodically and/or per your hospital protocol, verify that the baby’s eyes are
protected and free of infection. Patients adjacent to the light may also need to
be protected with eye patches or equivalent.

LEDs have minimal light output degradation over their lifetime with proper
use. Nevertheless, the user can adjust the output of the LEDs for any
degradation using the two potentiometers. Life testing has shown neoBLUE
LEDs can emit high intensity phototherapy for over 40,000 hours. Actual
results may vary based on environmental factors and adjustments to the
potentiometers.

Timer

The neoBLUE light is equipped with a timer to track the total number of hours
it is switched on. The timer will count up to a maximum of 9999999.9 hours.
The decimal point will be flashing at a steady rate when the timer is counting.
When the timer is not counting, the decimal point will not flash. The timer will
count any time the lighted green on/standby switch is in the on position. The
timer will count at the same rate regardless of the intensity setting at which

neoBLUE® LED Phototherapy System User Manual 2
PN 001364 Rev. I

the device is being used. The last digit refers to tenths of hours, with 0.1 = 6
minutes. To reset the timer, please refer to the service manual.

Phototherapy Roll Stand

The roll stand is designed to hold the neoBLUE light with a base designed to
accommodate the weight distribution of the light enclosure at any height or
angle.

Warning! If an alternative stand is used, care must be taken to

validate the load capacity. See Regulatory/Safety Standards (Section 8).
Caution: Use care when repositioning the roll stand around other

equipment to prevent accidental change or damage to surrounding
equipment.

The roll stand operates on a gas shock to maintain a safe pole height during
adjustments.

The roll stand incorporates features to adjust the height, tilt and proximity of
the light source as described in Section 3.1.

Power Requirement and Accessories

The light is mains-power operated. The power cord plugs into a receptacle at
the power inlet at the back of the light enclosure. There are no single-use
components for the light. A power cord strain relief bracket is provided to hold
the power cord in place.

Lighted Green On/Stand-by Switch

The lighted green switch (between the target light switch and the intensity
switch) is used to turn the device on or put it in stand-by mode. The switch
should only be illuminated when in the on position. When in the stand-by
position, line voltages are still present inside the device if the device is
plugged in, but no DC voltage is being switched to the LED panel, fans or
timer.

Accessory Pack

An accessory pack is included with each light enclosure. The accessory pack
contains the following items: a CD, a power cord, a power cord strain relief
bracket to hold the power cord in place, vent filters and extra thumb screws
and mounting posts for attaching the light enclosure to the roll stand.
