Instruction Manual
Model: AES-U211

Version:1.0
Date modified: 2020-09-25
Please read this instruction manual carefully before use

Introduction

Thank you for purchasing the Arm Blood Pressure Monitor. The blood pressure monitor uses the oscillometric method of blood pressure measurement. This means the monitor detects your blood’s movement through your brachial artery and converts the movements into a digital reading. An oscillometric monitor does not need a stethoscope so the monitor is
simple to use.
The Blood Pressure Monitor comes with the following components:

  • Monitor
  • Arm Cuff
  • Instruction Manual

Please read this instruction manual thoroughly before using the unit.
Please keep it for future reference.
For specific information about your own blood pressure, please consult your doctor.

Indications for Use

The Arm Blood Pressure Monitor is intended to measure the systolic and diastolic blood pressure as well as the pulse rate of an adult person via a non-invasive oscillometric technique in which an inflatable cuff is wrapped around the upper arm. It can be used at medical facilities or at home. The intended upper arm circumference is 22-42cm. Suitable for adults who over the age of 12.

Unit Description

Display

Charging the Battery

The blood pressure monitor comes with a rechargeable Li-ion battery inside. Use a Type-C USB cable to charge the monitor. will appear on the screen when the monitor needs to be charged.

  1. Insert one end of the USB charging cable into the Type-C power socket on the side of the monitor.
  2. Insert the other end of the USB charging cable into a DC 5V, 1A adapter outlet or a powered USB outlet.
  3. When the blood pressure level indicator is full grid display, means that the battery is fully charged.

Note:

  • Charging may take 3-4 hours.
  • Every 2 months (or when battery life is significantly shorter), fully charge the monitor and then allow the battery to drain until the monitor shuts off. This will optimize battery performance.
  • Battery life depends on frequency and time of use. If battery life is unusually reduced, please contact Customer Support.
  • In extreme conditions, the battery may leak corrosive fluid. If this comes into contact with eyes or skin, rinse immediately with water and seek medical attention.
  • Only use a Type-C USB charging cable to charge the monitor, do not insert the adapter when using the product.

Adapter use

  1. The optional AC adapter should comply with the requirements of IEC 60601-1, and all configurations should meet the requirements of the medical electrical system. Please note that local laws take precedence over the above requirements. If any doubt, please consult your local representative or technical service department.
  2. When using AC power, select the power cord of the Type-C jack, and plug it into the power jack.
  3. To remove the AC adapter, first unplug the adapter from the outlet and then disconnect the power cord from the device outlet.
    Adapter parameter requirements:
    Output voltage: DC 5V
    Maximum output current: at least 1A
    Type-C socket

Setting the Measurement Unit

In shutdown mode, press and hold the “ ”button for about 10 seconds, unit symbol “PA” appears. Then press the user “ ” button to change between ON and OFF, ON for kPa, OFF for mmHg, press the user “ ” button to confirm and power off the device.

Precautions for Measurement

To ensure a reliable reading follow these recommendations:

  • Avoid eating, drinking alcohol, smoking, exercising, and bathing 30 minutes before taking a measurement. Rest for at least 5 minutes before taking the measurement.
  • Stress raises blood pressure. Avoid taking measurements during stressful times.
  • Use the same arm when repeating the measurement, and if it is your first time measuring your blood pressure, measure both of your arms.
  • Remove tight-fitting clothing from your arm.
  • Sit on a chair with your feet flat on the floor. Rest your arm on the table so that the cuff is at the same level as your heart.
  • Please sit down and be quiet, do not talk, and move your body during the measurement.
  • Patients with arrhythmia and atherosclerosis should not measure by themselves if there is no medical staff there.
  • Avoid any electromagnetic interference or noise interference during measurement.
  • Keep a record of your blood pressure and pulse readings for your physician. A single measurement does not provide an accurate indication of your true blood pressure. You need to take and record several readings over a period of time. Try to measure your blood pressure at the same time each day for consistency.

Applying the Arm Cuff

  1. Make sure the air plug is securely inserted into the main unit.
  2. Remove tight-fitting or thick clothing from your upper arm. Do not wear any accessories, please bare upper arm or wear a thin shirt for measurement.
  3. Apply the cuff to your left upper arm.
  4. Do not wrap the cuff too tight, the bottom of the cuff should be about 2-3cm above your elbow.
  5. After wrappingping, the cuff put the air tube on the inside of your arm and make it aligned with the middle finger.
  6. If it’s not convenient to measure with the left arm, please measure with your right arm following the instructions as below.

Correct Measurement Posture

  1. Correct posture: sit on a chair as shown in the figure below with your feet flat on the floor.
    Place your arm on the table so the cuff is level with your heart. Relax for the measurement.

  2. Keep quiet during the measurement. Do not shake, talk or eat to avoid inaccuracy.

  3. Since blood pressure can vary from time to time throughout the day, please take measurements at the same time every day to ensure reliability.

Taking A Measurement

  1. Press the “ or user “ ” or user “ ” button, the monitor will fully display and start the measurement. It will automatically check whether the arm cuff is applied correctly during the measurement process. When the cuff is applied correctly, is displayed, otherwise is displayed, need to reapply the arm cuff. During the inflation process, the monitor also detects the pulse rate, please do not move until the entire measurement process is completed. As the cuff deflates, decreasing numbers appear on the display, the Heartbeat Symbol ( ) flashes at the same time. When the measurement is complete, the arm cuff deflates automatically, the blood pressure value and pulse rate appear on the display. The difference between the three buttons for measurement is that the blood pressure values measured by pressing the user “ ” or user “ ” button will be uploaded and saved in the background server in the corresponding account for health management.
    When the measurement data is uploaded, the wireless communication symbol “ ” flashes and then lights up. But the results of blood pressure measured by pressing the “ button are only displayed on the monitor, and will not be uploaded to the background server.

  2. In very rare cases, higher pressure inflation may be required. At this point, the monitor will automatically re-inflate to about 40mmHg higher than the initial inflation, and then re-measure, without affecting the measured value.

  3. After finishing, the measurement, the blood pressure value, and pulse rate will display on the screen. Press the “ ” button to turn the monitor off. Or the monitor will automatically switch off after about two minutes of inactivity.

Care and Maintenance

Cleaning the monitor and cuff

Make sure the monitor is off prior to cleaning, it can be sterilized with 75% medical alcohol on the soft towel or cotton sliver.
