The AILE Upper Arm Electronic Blood Pressure Monitor, Model No.: FC-BP131, is a medical device designed for the non-invasive measurement of systolic and diastolic blood pressure and pulse rate in adult individuals. It utilizes the oscillometric method, detecting the movement of blood through the brachial artery and converting it into a digital reading. This method simplifies use as it does not require a stethoscope.

Function Description

The device is intended for intermittent measurement of human body blood pressure from the upper arm. It features a large screen display for clear readings and offers both kPa and mmHg display switching and measurement functions.

A key feature is the WHO warning strip "■" symbol display function. As blood pressure values change, the "■" symbol will appear in a higher position on the display, indicating higher blood pressure levels according to WHO definitions.

The monitor includes a double memory lookup function, capable of storing 120 sets of measurement values for each of two users, totaling 240 records. This allows users to track their blood pressure status over time. The device can also calculate and display the average of the last three measurements, which is accessible by pressing the memory key.

For user convenience, the monitor incorporates several automatic functions:

Automatic Inflation: The cuff inflates automatically when a measurement is initiated.
Automatic Rapid Deflation: After measurement, the cuff deflates automatically.
Automatic Shutdown: The device will automatically shut down after 2 minutes of no operation to conserve battery life.
Low Power Detection: A " " symbol on the LED display indicates low battery power.
Overpressure Protection: If the pressure exceeds 300mmHg, the device will automatically consume power quickly to prevent over-inflation.

The device also provides heartbeat prompting and measurement completed prompting functions, along with an incorrect prompting function to guide the user. An irregular heartbeat (IHB) symbol will be displayed if an irregular rhythm is detected two or more times during a measurement, defined as a rhythm more than 25% slower or faster than the average rhythm.

Usage Features

The monitor is designed for ease of use. To begin, ensure the air plug is properly inserted into the main unit. For accurate readings, remove all clothing from the upper arm so the cuff fits directly on the skin. Sit in a chair with feet flat on the floor, placing the arm on a table to level the cuff with the heart. The cuff should be wrapped tightly around the upper arm, with the hose running down the inside of the arm, approximately 0.8-1.2 inches (2-3cm) above the elbow. Ensure there is 1-2 fingers' space between the arm and cuff. Relax the arm with the palm upward and fingers naturally curved before starting a measurement.

To take a measurement, simply press the "START/STOP" button. All display symbols will appear, and the cuff will inflate automatically. The heartbeat symbol will flash when a pulse is detected, and the device will calculate the pulse. Once the measurement is complete, blood pressure and pulse rate will be displayed, and the cuff will deflate. The results are automatically stored in memory. The inflation or measurement can be stopped at any time by pressing the "START/STOP" button.

The memory function allows users to review past measurements. When the unit is off, pressing the "MEM" button will display the average of the last three measurements for the current user. Subsequent presses of the "MEM" button will cycle through the latest measurement values. The device supports two users, and the user can be switched by pressing the "SET" button when power off, and then pressing "SET" again. Memory records for a user can be deleted by long-pressing the "MEM" button in memory mode, then confirming with the "START/STOP" button.

The unit can be powered by 4 AAA alkaline batteries (not included) or via a USB Type C (DC5V1A) connection.

Maintenance Features

To ensure the longevity and accuracy of the blood pressure monitor, proper care and maintenance are essential:

Cleaning: Clean the device frequently after use. Use a soft, dry cloth; for heavy soiling, a damp cloth with neutral detergent can be used, ensuring it is wrung out well. Do not use abrasive or volatile cleaners, and never immerse the unit or any components in water. The cuff can be disinfected with 75% alcohol cotton wool.
Storage: Store the unit in a safe, dry location, away from extreme hot or cold temperatures, humidity, and direct sunlight. Avoid folding the cuff too tightly.
Handling: Protect the unit from strong shocks, such as dropping it on the floor.
Battery Management: If the unit will not be used for three months or longer, remove the batteries to prevent leakage, overheating, rupture, and damage. Always replace all batteries with new ones simultaneously when exhausted.
Repair and Service: Do not attempt to repair or open the machine yourself. In case of a defect, contact the local distributor. The manufacturer can provide circuit diagrams, component lists, calibration instructions, and other information to trained service personnel.
Calibration: The monitor is designed for a long service life, but it is recommended to have it inspected every two years to ensure correct functioning and accuracy. Consult a local authorized distributor or dealer for this service.
Accessories: Only use authorized parts and accessories with the unit.

The device is designed to be robust, but users should be aware of potential error indicators displayed on the screen, such as "Err" for inflation errors or a low battery symbol, which prompt corrective actions like re-wrapping the cuff or replacing batteries. Troubleshooting guidance is provided for common issues like no power or incorrect readings.
