General; Principle Of Operation; New Technologies Used - scian LD-588 Instruction Manual

GENERAL

This instruction manual is intended to assist the user for safe and
efficient operation of the automatic digital blood pressure monitor
(hereinafter: device) model LD-588. The device must be used in
accordance with the procedures described in the manual. It is import-
ant to read and understand the entire manual, especially the section
<Tips on taking blood pressure measurement>.
This device is intended for the non-invasive measurement of systolic
and diastolic arterial blood pressure and pulse rate in adults（age 15
and above）.

PRINCIPLE OF OPERATION

This device adopts the oscillometric technology with Fuzzy Algorithm
measuring the arterial blood pressure and pulse rate. The cuff is
wrapped around the arm and automatically inflated by the air pump.
The sensor of the device catches weak fluctuation of the pressure in
the cuff produced by extension and contraction of the artery of the arm
in response to each heartbeat. The amplitude of the pressure waves is
measured, converted in millimeters of the mercury column, and is
displayed by digital value.
Annotation: This device can not provide reasonable accuracy if
used or stored in the temperature or humidity beyond the range
stated in the section <SPECIFICATIONS> of this manual.

NEW TECHNOLOGIES USED

Fuzzy Algorithm is the processing algorithm taking into account of
the speciality of individual heartbeats, which provides higher accuracy
of measurement.
