Integrated Infant Scale
With the optional, fully integrated incubator infant scale, patient
weight can be determined without having to remove the infant
from the protective climate of the incubator. Even with the built-
in scale, the use of the x-ray drawer remains possible. In order
to be weighed, the infant must be lifted once in order to reset
the scale to zero (tare weight). The infant can then be placed
back on the mattress. The current and previous weights are
displayed for information. The results of the last 30 weighings
can be graphically represented in the trend display.
Weighing without lifting the infant again (i.e. without obtaining a
new tare weight) is possible. This option is useful when the
weight has to be taken again for verification purposes shortly
after the first weighing, or if, e.g. the weight with full and empty
diaper needs to be determined. The entire weighing procedure
is guided by brief audible signals, so that the operator's full
attention can remain with the patient.
When weighing the infant inside an incubator, great care must
be taken that no hoses or cables are jammed by the bed or
otherwise distort the weight measurement. If the weight is
determined with hoses and cables attached to the infant, best
results are obtained if hoses and cables are removed from the
ventilator circuit support arm of the bed and laid onto the bed
surface as horizontally and as strain-free as possible.
The infant scale in the Caleo comprises four weighing cells
located underneath the bed, an electronic measuring and
analysis unit and a special page on the control monitor. In
normal mode, the entire bed rests on these four weighing
elements under the bed. A safety system prevents the
weighing elements being damaged if loads of more than 10 kg
are applied. When removing the bed, it is first raised slightly by
turning two knobs so that it can then be pulled out gently.
