GENERAL INFORMATION
This Instruction Manual is designed to assist the user with safe and eff ective operation
of the automatic digital Device for measurement of blood pressure and heartbeat rate
LD, (modifi cation LD7) (hereinafter – the “Device”). Use this Device according to the
rules described in this Manual. Operate the Device only as intended. Do not use the
Device for any other purposes. Read and understand the whole Instruction Manual,
in particular “Recommendations on Correct Measurement”
.
INDICATIONS FOR USE
Use this Device to measure your systolic and diastolic blood pressure and heartbeat
rate in patients aged from 15. This Device is recommended for use by persons with
unstable blood pressure or known arterial hypertension at home as an addition to
medical surveillance.
OPERATION PRINCIPLE
This Device uses the oscillometric method of blood pressure and pulse rate
measurement. Wrap the cuff around your upper arm and it starts to be inflated
automatically. The sensitive element of the Device feels the weak pressure oscillations
in the cuff generated by widening and contraction of the brachial artery in response
to every heartbeat. Pumping in is ceased when cuff is adequately pumped in to
determine diastolic and systolic pressure (the amplitude of the pressure waves is
measured, converted into millimeters Hg and shown on the display as fi gures). This
device has 2 memories 60 cells each used for storage of measurement results and a
clock with calendar and alarm features. An individual digital thermometer is integrated
in the device for measurement of room temperature. Remember that the Device will
not maintain the mentioned accuracy of a measurement if it is used or stored at a
temperature or humidity other than those specifi ed in Technical Specifi cations of this
Manual. We are warning about possibility of mistakes in blood pressure measurement
with this Device in persons with pronounced cardiac arrhythmia. Consult the doctor
concerning blood pressure measurement of your child.
APPLIED NEW LD TECHNOLOGIES
Fuzzy Algorithm
– algorithm for processing the measurement values
with regard to peculiarities of the man’s heartbeat, thus, ensuring high
measurement accuracy.
Scale WHO
– classification of measurement results according to
recommendation of World Health Organization (WHO).
Indication of arrhythmia
– special symbol «
» on Device display
informs about availability of irregular pulse; in this case.
WARNING!
This Device may be used only with cuff :
