JZ-253A Automatic Smart Wrist Electronic Blood Pressure Monitor with Voice Broadcast

Description:
The electronic sphygmomanometer is a convenient and feasible medical device developed by the use of modern electronic technology and the principle of indirect blood pressure measurement. A series of complex conversions and calculations get the data of systolic and diastolic blood pressure.
Because the pressure measured by the wrist sphygmomanometer is the "pulse pressure value" of the wrist artery, it is particularly suitable for most middle-aged and elderly people, especially those with high blood viscosity, poor microcirculation, and patients with vascular sclerosis. Crowd, for personal monitoring-you can keep track of your own "blood pressure" changes at any time.
Wrist sphygmomanometer: small and light, easy to carry, measuring the arterial blood pressure of the wrist anytime, anywhere. The wrist sphygmomanometer is convenient without taking off your shirt, especially in winter when you wear more clothes. So the wrist style will be very convenient.

Main Features:
● Indicator light: with green, orange, and red blood pressure status indicator, the blood pressure health status is clear at a glance!
● Measurement method: wrist electronic sphygmomanometer, step-down measurement/oscillometric method.
● Display screen: LCD digital display, the result shows high pressure/low pressure/pulse, large screen and big characters, clear reading.
● Blood pressure classification: WHO sphygmomanometer classification indicates blood pressure health status, which is convenient for users to accurately judge whether blood pressure is normal.
● Intelligent compression: automatic compression and decompression, IHB arrhythmia detection.
● Clock function: year, month, day, hour, minute setting.
● Stored data: Two-person memory of 99 groups of measurement results, which can display the average reading of the last 3 measurement results, which is convenient for users to retrieve data for comparison.
● Automatic shutdown: manual shutdown or automatic shutdown after 1 minute of no operation, simple and convenient operation.
● Unit conversion: two display units conversion of blood pressure value unit Kpa and mmHg (the default unit is mmHg at startup).
● Overpressure protection function, when the air pressure exceeds 295mmHg-20ms, it will automatically and quickly exhaust.
● Error prompt function to facilitate users to find the source of the error.
● Low battery detection function, low battery is detected under any working status, LCD display indicates low battery.
● Advantages: One-button measurement, heart rate monitoring, comfortable cuff, large screen and big characters, intelligent pressure, precise measurement, small and exquisite, easy to carry.
