Dräger Babytherm 8004 Instructions For Use Manual page 119

Babytherm consists of:
– a chassis with infant bed and stand
– a control unit with operating panel
– a radiant warmer and
– a heated gel mattress (for Babytherm 8010).
Control unit
The control unit is positioned at the head end
underneath the radiant warmer and between the
columns of the stand. It has an operating panel and
display, and an integral text display with 2 x 40
characters for easier user guidance.
Radiant warmer
The radiant warmer contains two infrared ceramic
radiating elements and 2 lamps for illuminating the
bed surface.
The bed surface lighting can be adjusted for
working lighting and night lighting. The good colour
reproduction of the lamps ensures easier detection
of diagnostically important skin colour nuances.
The radiant warmer can be operated in "manual
control mode" or "baby control mode". In manual
mode, fixed heater levels of 1 to 10 are set.
In "baby control mode", the skin temperature is
constantly adjusted towards a preselected optimum
setting. In this mode, the output level of the radiant
warmer is automatically adjusted to the needs of
the patient.
In both modes, self-check routines and alarm
systems provide appropriate system monitoring.
ThermoMonitoring
Thermal monitoring is possible with a second skin
temperature sensor. Skin temperatures readings
are displayed on the controller and can be
graphically represented by means of the optional
interface (RS 232) and a monitor. This facility
improves the diagnostic possibilities of the system.

Construction and description
Phototherapy
Light from the halogen lights contributes to
photochemical breakdown of the bilirubin in the
skin. Dräger halogen lights emit particularly
effectively at wavelengths around 460 nm. Unlike
the phototherapy units of the past, the colour of the
light is not blue, and so the skin colour is accurately
visible. Phototherapy is switched on/off from the
operating panel on the control unit.
Mattress heater
The heated gel mattress consists of the following
components: gel mattress, aluminium heating plate
and an electronic monitoring and control unit.
The gel mattress consists of a highly heat-
conductive gel that does not run or dislocate even
when the bed is tilted. The gel is surrounded by a
film of soft material compatible with the skin.
The mattress molds itself to the body contours of
the patient resting on the mattress. This creates a
large contact area that conducts the heat to the
patient and avoids pressure points. When the gel
mattress is cold, warmth is transferred from the
patient to the mattress.
The gel has good heat storage properties. If the
mains supply is interrupted, e.g. for in-hospital
transport, the patient will be kept warm for about
15 minutes, provided the insulation is sufficient
(blanket, bed canopy).
The heating system consists of a thick aluminium
plate and a heater element below the plate. This
system ensures that heat is distributed evenly over
the entire bed surface.
The control and display panel for the heated gel
mattress is located on the right-hand side of the
control unit.
The mattress temperature is adjusted with
reference to a set temperature entered by the user.
The set temperature is only attained in the areas
where the patient is in contact with the mattress.
System monitoring includes self-check routines
and alarms.
