Introductory information
Your boso ABI-system 100 is an innovation on the market for blood pressure mea-
surement. It represents an easy way to determine the ankle-brachial index (ABI) and
works according to the oscillometric measurement principle. The pressure variations
(oscillations) caused by the pulse waves and transmitted by the cuffs are saved and
evaluated by the microprocessors. The main advantage of this type of measurement
is that there is no need for a microphone or duplicator whose positioning is crucial
in terms of achieving accurate results.
This device complies with the European directives based on the German Medical
Devices Act (label: CE0124) and with European standard EN 1060, part 1: “Non-
invasive sphygmomanometers – general requirements” and part 3: “Supplementary
requirements for electro-mechanical blood pressure measuring systems”.
Technical testing – to be performed every 2 years at the latest – can either be carried
out by the manufacturer, or the authorities or persons responsible for metrology, all
of which must meet the requirements of the Medical Devices Operator Ordinance
§ 6. Technical testing instructions can be found on page 23 of these user
instructions.
Electrical medical devices are subject to specific precautionary measures with regard
to electromagnetic compatibility, and must therefore be installed and operated accor-
ding to the Electronic Compatibility Act information listed on pages 24 and 25.
