ment.

Description of device • 27
English
2.2 Intended use
The seca mechanical baby scale is mainly used in hos-
pitals, doctors' surgeries and inpatient care facilities in
accordance with national regulations.
The scale is both for determining birth weight and
checking weight gain during the growth process, and it
supports the doctor supervising treatment in making a
diagnosis or deciding on a treatment.
In order to make a precise diagnosis, however, other
specific examinations must be set up by the physician
in addition to determination of weight and their results
taken into account.
2.3 Description of function
On mechanical scales, weight is determined by a load
lever system. To display the weight, the user moves
two sliding weights on a beam until the beam is
balanced. The patient's weight can then be read off at
the position of the sliding weights.
Use the scale only for the purpose quoted in the
section entitled “Intended use”.
2.4 User qualification
The device may only be operated by healthcare
professionals.

Handling the
measurement results
WARNING!
Patient hazard
This device is no diagnostic device. It simply
assists the treating physician in establishing a
diagnosis.
– In order to make a precise diagnosis and
initiate therapeutic measures, besides
determination of the weight, further targeted
examinations must be set up by the
physician, and their results must be
considered.
– The responsibility for diagnosis and treatment
lies with the treating physician.
NOTICE!
Inconsistent measuring results
• Before you save measurement values deter-
mined using this device and use them further
(e.g. in seca PC software or in a hospital infor-
mation system), make sure that the measure-
ment values are plausible.
• If measurement values are transmitted to seca
PC software or a hospital information system,
make sure prior to further use that the meas-
urement values are plausible and are assigned
to the correct patient.
Handling the packaging
material
WARNING!
Risk of suffocation
Packaging material made of plastic foil (bags) is
a choking hazard.
– Keep packaging material out of reach of
children.
– In the event that the original packing material
may not be available anymore, only use
plastic bags with security holes in order to
reduce the risk of suffocation.
