Infra-red radiant warmer
The radiant warmer is used for pre-warming the
patient deck and for maintaining the patient's body
temperature during the treatment. It generates
long-wave infra-red radiation energy in the far non
visible infra-red range.
The patient's upper skin layers are warmed-up and
small blood vessels expand. So the metabolism is
activated and the transport of heat in the blood is
accelerated.
The long-life ceramic heating element does not scale and is not affected by slight liquid splashes.
The radiation intensity emitted to the patient deck is selected defined in mW/cm². As an option the
selection can be changed into "heating capacity in percent". The selection and the radiation intensity
respectively the heating capacity (%) actually emitted to the patient deck are permanently displayed.
Deviations from the selected radiation intensity respectively heating capacity (% ) as well as system
faults and power failure are alerted visually and audibly
At intensity selection above 10 mW/cm², after 15 minutes the radiant warmer automatically reduces
the intensity to a safe value and alerts visually and audibly. The user can now reduce the intensity/
capacity selection or confirm the high intensity/capacity selection by keypress for the next 15 minutes.
For certain applications this safety function can be switched-off temporarily by a conscious action.
Refer to chapter 6.4 "Functions of the infra-red radiant warmer" as well as chapter 6.6.3 "Automatic
intensity reduction".
For even and dazzle-free illumination of the patient deck two panel lights are integrated in the radiant
warmer, their brightness can be adjusted in 5 steps. The colour temperature of 4000 Kelvin is optimal
for visual examination of the patient.

6. Use
6.1 Indications / Contraindications / Adverse effects
6.1.1 Indications
Prevention and reduction of temperature loss in the patient.
Loss of vital functions as well as ambient influences as a result of which the patient cannot maintain his body
temperature.
Hypothermia, e. g. after surgery or transport.
6.1.2 Contraindications
Infra-red radiation results in vascular dilatation. Therefore in case of doubt, medical advice should be
obtained, in particular in case of infections, shock or fever, inflammations and injuries, erythema, swellings of
skin, bleeding and multiple sclerosis.
6.1.3 Adverse effects
Under certain circumstances radiation intensity above 10 mW/cm² can cause hyperthermia to infants.
Therefore the body temperature must be checked frequently or monitored.
Application of infra-red radiant warmers can cause a significant humidity loss in the infant and the demand of
oxygen may rise.
Longer application of the radiant warmer will dehydrate the skin and can increase the water loss, in particular
in babies and infants.
Sunlight, draught, cold exterior walls and windows in direct ambience to the radiant warmer will impair the
patient's temperature balance.
In case of operation above 10 mW/cm² and therapy-related switched off automatic intensity reduction, the
patient's skin temperature can increase above 40° C. Therefore the patient's temperature must be checked
frequently.
6.2 Warnings for use
The examination and treatment table Easy Care must only be used under medical supervision by
qualified persons who are familiar with the use and commonly known risks of infra-red radiant warmers.
The patient must never be left unattended on the patient deck.
The user is recommended to have always one hand at the patient while being on the patient deck. The
front end of the patient deck has no boundary and so there is no protection from falling from the patient
deck.
6.2.1 General
The examination and treatment table Easy Care is not suitable for the use in explosion-hazardous areas.
The ambient conditions for the examination and treatment table must not be influenced in any case by non-
compatible warming or air condition devices. The uncontrolled use may cause hazard to the patient.
The device is not intended for simultaneous use of other warming therapy devices, e.g. heated pads, as well
as of phototherapy devices.

Instruction for use Examination and treatment table Easy Care
** Depending on model and configuration
D2151_01 - 09/2017 11/38
The intensity display of the radiant warmer does not give an indication as to the patient's body temperature.
Therefore the patient's temperature must be checked at regular intervals or monitored.
Sunlight, draught, cold exterior walls and windows in direct ambience to the radiant warmer will impair the
patient's temperature balance.
6.2.2 Adjustment **
During height-adjustment make sure that no device components or additional devices connected to the
warming bed can clash with furniture items or other devices in the ambience.
It should be considered that the distance to accessories, which are not fixed at the examination and
treatment table Easy Care, will change during height adjustment and connected lines and tubes may break
or be pulled off.
Before moving the examination and treatment table Easy Care, it is recommended to adjust it to the lowest
position. Otherwise it may topple over when moving over thresholds and obstacles.
6.2.3 Radiant warmer
When using radiant warmers it must be considered that humidity loss in patients can increase unconsciously.
The intensity display refers to the patient deck. The radiation intensity reaching the patient's skin is approx.
4 mW/cm² higher than the displayed value because the distance of the radiant warmer to the patient's
surface is approx. 10 cm shorter than to the patient deck.
In the length of time radiation intensity above 10 mW/cm² may bring the patient in a hyperthermic condition
and increase the skin temperature above 40 ° C
In case of long-term operation at high intensity the surface temperature of the radiant warmer can heat up
above 85°C. Therefore during operation it should be avoided to touch the safety guard or the top of the
radiant warmer.
Take care that mature infants cannot grip into the safety guard and suffer from burnings.
In the length of time at high radiation intensity in particular dark coloured surfaces within the field of radiation
can heat up above 43°C
No objects, medical drugs or infusion fluid must be placed above the radiant warmer or within the irradiated
area. These might warm up or can even become dangerously hot.
6.2.4 Patient deck
The user is recommend to always have on hand at the patient while being on the patient deck. The front end
of the patient deck has no boundary and so there is no protection from falling from the patient deck.
The pad does not allow electrostatic discharge, is not autoclavable and not washing-machine proof
Before each operation the patient deck and the pad must be checked for mechanical damages
The pad can only be bent slightly. Sharp instruments like needles, knives or scissors will damage or even
destroy the pad.

6.6 Infrared radiant warmer
The radiant warmer generates long-wave radiant heat.
The radiation intensity effective to the patient is
selected at the head end of the device.
For even and dazzle-free illumination of the overall
patient deck two dimmable large-area lamps are
integrated in the radiant warmer which can be switched
on at the head end of the device, if required.
Under unfavourable circumstances parts of the radiant warmer can reach temperatur above 85°C.
During operation it should be avoided to touch the safety guard and the top of the device. In particular
for matrue infants it must be taken care that they do not grip into the safety guard. There is a risk of
burning injuries!!
6.6.1 Switching on the heating
If the radiant warmer is in stand-by mode (display is off and the
information lamp flashes, this mode must be exited by pressing
any key.
Switch on the heating by pressing the left-hand key (1). The green
pilot lamp (6) above the key lights up and the radiant warmer starts
heating.
The default value for the heating is factory set to 10 mW/cm².
When the radiant warmer shall start with a lower intensity in
general, this default value can be adjusted as described in chapter
7.2.

The radiation intensity of 10 mW/cm² is usually sufficient to maintain the body temperature of an
unclothed healthy infant at an ambient temperature of 24° C.
Now the selected default value for the radiation intensity is indicated by an LED spot (11.4) as well as by a
numeric display (11.6).
The information lamp (10) flashes for 15 seconds. During these 15 seconds the radiation intensity can be
adjusted with the rotary push-button (5) according to the requirements and confirmed by pressing. If the
selection is not changed, the radiant warmer starts operating with the default value.
After short heating-up period the actually emitted radiation intensity is indicated as LED bar graph in the
actual intensity display (11.7). E.g. at an intensity selection 10 mW/cm² the bars 4, 6, 8 mW/cm² light-up pro-
gressively. A flashing bar indicates that the selected intensity is not yet reached. The selected intensity is
reached when the bar on the left hand side of the LED spot lights up.

Depending on the start and ambient conditions the ceramic heating elements require approx.
10 - 15 minutes until the selected intensity of 10 mW/cm² is reached.
If the radiant warmer shall operate generally in manual mode [%] then the mode can be changed as
described in chapter 7.2. The sequence of operation described before applies analogously.

6.6.2 Adjustment of radiation intensity
When the radiant warmer has been switched on as described before and the selected intensity was
resumed, the desired radiation intensity can be adjusted in the same way.
Press key heating on/off (1) in order to enter the intensity adjustment.
The green LED (6) and the information lamp (10) flash. During the next
15 seconds the new intensity can be selected with the rotary push-
button (5).
The newly selected radiation intensity is indicated by an LED spot (11.4)
as well as by a numeric display (11.6) When the selected value shall be
resumed, this must be confirmed by pressing the rotary push-button (5).
If for 15 seconds after entering the intensity adjustment the selection
was not changed and confirmed, the previous selection is maintained
and the information lamp (10) stops flashing.
When selecting an intensity above 10 mW/cm² the radiant warmer
operates in the extended selection range and the colour of the LED
spot (11.4) changes from green to orange. After confirmation by
pressing the rotary push-button, a green LED spot (11.5) lights up. The
position of this LED spot corresponds to the default value after switching
on the heating (factory setting 10 mW/cm²) and indicates the value to
which after 15 minutes the intensity will automatically be reduced.
Furthermore the balance time to the next automatic reduction is
indicated above the selected and actual intensity display (11.8).
After short heating-up period the actually emitted radiation intensity is
indicated as LED bar graph in the actual intensity display (6.11.7). At an
intensity selection of 10 mW/cm² the bars 2, 4, 6, 8, 10 mW/cm² light-up
progressively. A flashing bar indicates that this intensity step will be
reached next. The selected intensity is reached when the bar is at the
same level as the LED spot and lights up.
The intensity selection mainly depends on the infant's weight, age, skin colour, maturity, the anamnesis as
well as the ambient conditions.

The smaller and immature the infant, the higher is the heat demand.
The lower the ambient temperature, the higher is the heat demand.
If there is no experience regarding the intensity selection, for an unclothed infant 10 mW/cm² should be
selected initially. The body core temperature must be checked in regular intervals. If necessary, the intensity
selection must be adapted according to the measured patient temperature.
The intensity selection is ideal when neutral thermal conditions are available, i.e. when the patient's body
core temperature in relaxed condition is between 36.7 and 37.3°C.

The intensity display refers to the patient deck. The radiation intensity reaching the patient's skin is
approx. 4 mW/cm² higher than the displayed value because the distance of the radiant warmer to the
patient's surface is approx. 10 cm shorter than to the patient deck.

The temperature display does not give any indication as to the patient's body temperature. Therefore
the patient's temperature must be checked at regular intervals or monitored.
The maximum radiation intensity that can be reached in the examination and treatment table is 20 mW/cm².

6.6.3 Automatic intensity reduction
Under certain circumstances at radiation intensity above 10 mW/cm² infants can suffer from hyperthermia.
Therefore the radiant warmer provides an automatic intensity reduction which reduces the intensity to the a
safe value (factory setting 10 mW/cm²) after 15 minutes.

The factory set default value 10 mW/cm², to which the intensity is automatically reduced after
15 minutes, can be changed to 8; 6; 4 or 2 mW/cm², as described in chapter 7.2.
When an intensity above 10 mW/cm² was selected and confirmed, it is in
the extended selection range and the colour of the LED spot (11.4) is
changed from green to orange. After confirming a selection within the
extended range a second, green LED spot (11.5) lights up. The position of
this LED spot corresponds to the default value after switching on the
heating (factory setting 10 mW/cm²) and indicates the value to which the
intensity is automatically reduced after 15 minutes.
Furthermore the balance time to the next automatic reduction is indicated
above the selected and actual intensity display (11.8).
When the indicated balance time has elapsed, the intensity is automatically reduced to the intensity indicated
by the green LED spot (11.5). This is indicated by alternating flashing of the orange LED spot (11.4) for the
intensity selection and the greed LED spot (11.5) for the reduced value and a yellow flashing background of
the balance time display (11.8) and signalized by an audio alarm of medium priority.
Now check the patient's temperature and reduce the intensity selection if necessary. If the treatment in the
increased intensity range shall be continued, this must be confirmed by keypress (4). The audio alarm is
paused and the radiant warmer will supply the selected intensity for further 15 minutes. The orange LED spot
and the green LED spot as well as the yellow background of the balance time display stop flashing and the
balance time starts again at 15 minutes.
When the patient shall stay under the radiant warmer for longer time at an
intensity above 10 mW/cm² a surveillance of his body temperature is re-
commendable. When a continuous surveillance is guaranteed, the safety
function >10 mW/cm² can be switched-off temporarily by a conscious
action. For this purpose press key (4) for approx. 3 seconds until two
short tones sound and the balance time display (11.8) is replaced by a
yellow symbol .
When the safety function >10 mW/cm² shall be reactivated, press key (4) again for approx. 3 seconds
until one short tone sounds. The yellow symbol is replaced by the balance time display again and
15 minutes to the next reduction start to elapse.
The automatic intensity reduction must never be deactivated if the temperature surveillance of the
patient is not secured.

When the heating is switched-on anew, or after an intensity of 10 mW/cm² or lower was selected, in
principle the safety function is activated.

6.6.4 Switch off the heating
Switch-off the heating by pressing key (1) for approx. 2 seconds and the LED spot for the intensity selection
(11.4) extinguishes. As an alternative it is possible to reduce the radiation intensity to 0 mW/cm² and confirm.
The actual intensity display remains active until the residual intensity has fallen below 2 W/cm².
When all functions of the radiant warmer are switched off and the residual intensity is below 2 mW/cm², the
radiant warmer will automatically switch off the display after 2 minutes and change to stand-by mode. The
readiness of function is shown by repeated short lighting of the information lamp (10). When pressing either
key the stand-by mode is exited and the display (11) is switched on.
6.7 Illumination
For even and dazzle-free illumination of the overall patient deck two dimmable panel lights are integrated in
the radiant warmer which can be switched on at the head end of the radiant warmer, if required. The
brightness can be adjusted in 5 steps according to the requirements.
The colour temperature of the light sources is 4000 Kelvin and is optimal for a neutral appearance during
visual examination of the patient.
6.7.1 Switch on the illumination
If the radiant warmer is in stand-by mode (display is off and
the information lamp flashes), exit this mode by pressing
any key.
Switch on the illumination by pressing the middle key (2).
The green pilot lamp (7) above the key lights up and the two
panels lights illuminate.
The information lamp (10) flashes for 15 seconds. During these 15 seconds the brightness can be adjusted
with the the rotary push-button (5) and confirmed by pressing. During the adjustment the brightness changes
and the actual brightness level is indicated in the brightness display (11.10).
When no adjustment and confirmation is made within 15 seconds, the default value will be resumed.
6.7.2 Adjustment of brightness
For changing the brightness during operation, the brightness adjustment must be activated by pressing the
middle key (2). The information lamp (10) flashes for 15 seconds. During these 15 seconds the brightness
can be adjusted with the the rotary push-button (5) and confirmed by pressing. During the adjustment the
brightness changes and the actual brightness level is indicated in the brightness display (11.10).
6.7.3 Switch off the illumination
Switch-off the illumination by longer pressing the middle key (2).
When all functions of the radiant warmer are switched off and the residual intensity is below 2 mW/cm², the
radiant warmer will automatically switch off the display after 2 minutes and change to stand-by mode. The
readiness of function is shown by repeated short lighting of the information lamp (10). When pressing either
key the stand-by mode is exited and the display is switched on.
