1 GENERAL
This instruction manual is intended to assist the user in safe and efficient operation of the wrist type digital blood pressure monitor (hereinafter: device) model 1143. The device must be used in accordance with the procedures described in the manual. It is important to read and understand the entire manual, especially the section <Tips on taking blood pressure measurement>.
This device is intended for the noninvasive measurement of systolic and diastolic arterial blood pressure and pulse rate in adults (age 15 and above). Consult your physician before using this device on children or persons with arrhythmia.
PRINCIPLE OF OPERATION
This device uses oscillometric technology with Fuzzy Algorithm to measure the arterial blood pressure and pulse rate. The wrist cuff is wrapped around the wrist and automatically inflated by an air pump. The sensor of the device catches weak fluctuation of the pressure in the wrist cuff produced by extension and contraction of the artery of the wrist 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.
