How to use the reading aid sphygmomanometer
1. Instrument preparation
Open the sphygmomanometer so that the upper cover and the The cover bottom becomes a 90-degree angle (right angle). Open the mercury switch valve and install 4 AA batteries into the control box. Verify that the sensor is inserted into the jack on the control box.
2. Armband binding
Put the extended side of the leather tube down to the bend of the arm. The iron ring is provided with a penetration tube at the other end, and the penetration tube is inserted into the iron ring to form a loop shape, which is convenient for your arm to be inserted into the loop. Note that the probe (with a circular mark) should be aimed at the brachial artery pulsation point as far as possible (about 2cm above the arm curve and about 2cm away from the inner edge). The subject should sit upright and relax the arms, keeping the brachial artery level with the heart.
3. Inflate and pressurize
Turn on the power of the reading aid sphygmomanometer (the working indicator light is on), and pinch and release the balloon to inflate and pressurize. The machine is automatically awakened during pressurization. The sign of awakening is the synchronised percussive chirping with the balloon being pinched and released again and again. The compression height is generally 10-20mmHg higher than the systolic blood pressure. Note: Turn on the switch of the mercury storage bottle before turning on the power of the reading aid sphygmomanometer, and observe that the mercury storage automatically reaches the zero position. Reading-assistant light-display sphygmomanometer: After turning on the power, the light spot should be within the zero mark.
3. Air stabilization and deflation
It is advisable (but not required) to stabilize air properly after pressurizing to the required height, and then deflate and decompress , start observing.
4. Observing blood pressure
Deflate and decompress, enter the blood pressure area, and read the contraction from the configured pressure gauge at the first sound of rhythm call pressure, and read the diastolic pressure at the last beep.
What are the characteristics of the reading aid sphygmomanometer
1. The only method of measuring blood pressure recognized by the World Health Organization is the offset measurement method. The desktop mercury meter used adopts this measurement method. The desktop mercury meter measures accurately, but it requires certain knowledge of use and needs to be used with hearing aids, which is inconvenient to use. The reading-aid sphygmomanometer also adopts the offset sound measurement method, and scientifically improves the traditional mercury sphygmomanometer, making the measurement more accurate and more suitable for family and personal use.
2. The reading aid sphygmomanometer does not need to undress and roll up the sleeves during measurement, and can be measured directly through clothes. In winter, the results obtained through two or three sweaters are equally accurate. It is simple to use and deep. Popular with elderly customers with limited mobility.
3. The reading aid sphygmomanometer will have a continuous electronic beep between high pressure and low pressure. The value corresponding to the first beep is high pressure, and the last sound corresponds to low pressure. The sound prompts high and low pressure, making the measurement simpler and more intuitive, and you can measure your blood pressure by yourself.
4. The electronic prompt sound issued by the reading aid sphygmomanometer can accurately reflect the pulsation of the heart. The prompt tone is rapid, indicating that the heart is beating too fast. The beep is delayed, indicating bradycardia. Early diseases such as arrhythmia can be judged by analyzing the prompt sound, which cannot be achieved by any other electronic sphygmomanometer.
