2 ส่วนประกอบ

The McKesson Aneroid Sphygmomanometer typically includes the following components:

• มาโนมิเตอร์แบบแอนเนอรอยด์: The gauge that displays blood pressure readings. It features a luminescent dial and extended graduation marks for easy reading in various lighting conditions.
• Inflation Bulb: Used to inflate the cuff.
• Air-Release Valve: Located on the inflation bulb, used to control the deflation rate of the cuff.
• Nylon Cuff: A latex-free cuff designed to securely wrap around the arm. It includes a comprehensive marking system for proper placement.
• ท่อ: เชื่อมต่อปลอกแขน เครื่องวัดความดัน และลูกยางสูบลมเข้าด้วยกัน
• กระเป๋าใส่อุปกรณ์: A leatherette zippered case for convenient storage and transport.

4. Setup and Cuff Placement

Proper cuff placement is crucial for accurate blood pressure readings.

1. Select the Correct Cuff Size: Ensure the cuff size is appropriate for the arm circumference. The McKesson Adult Cuff is designed for arm circumferences of 23-40 cm. Refer to the cuff sizing chart below.
2. Prepare the Arm: Sit comfortably with your arm resting on a flat surface at heart level. Ensure the arm is bare or has only thin clothing. Avoid taking measurements after strenuous activity, bathing, or consuming caffeine/alcohol.
3. สวมปลอกแขน: Wrap the cuff firmly around the upper arm, approximately 1 inch (2-3 cm) above the elbow joint. The artery mark on the cuff should be aligned with your brachial artery (typically on the inside of the arm). The index line should fall within the range lines on the cuff.
4. เชื่อมต่อส่วนประกอบ: Ensure the tubing from the cuff is securely connected to the manometer and the inflation bulb.

5. คู่มือการใช้งาน

Follow these steps to take a blood pressure reading using your McKesson Aneroid Sphygmomanometer. A stethoscope (not included) is required to listen for Korotkoff sounds.

1. วางตำแหน่งตัวเอง: Sit upright with your back supported and feet flat on the floor. Rest your arm on a table so the cuff is at heart level.
2. Locate Pulse: Place the diaphragm of a stethoscope over the brachial artery in the antecubital fossa (inner elbow).
3. สูบลมเข้าปลอกแขน: Close the air-release valve on the inflation bulb by turning it clockwise. Rapidly inflate the cuff by squeezing the bulb until the manometer reads approximately 20-30 mmHg above your usual systolic pressure, or until the pulse sound disappears. Do not over-inflate.
4. ลดลมออกช้าๆ: Slowly open the air-release valve by turning it counter-clockwise, allowing the pressure to drop at a rate of 2-3 mmHg per second.
5. ฟังเสียง:
   • ความดันซิสโตลิก: Note the reading on the manometer when you hear the first clear, tapping sound (Korotkoff sound). This is your systolic blood pressure.
   • ความดันไดแอสโตลี: Continue to listen as the pressure drops. Note the reading when the sounds completely disappear. This is your diastolic blood pressure.
6. ปล่อยลมออกให้หมด: Once the diastolic pressure is noted, fully open the air-release valve to deflate the cuff completely.
7. การอ่านบันทึก: Record your blood pressure reading (Systolic/Diastolic). Wait at least 1-2 minutes before taking another reading.

6. การดูแลรักษา

Proper care will extend the life and accuracy of your sphygmomanometer.

• การทำความสะอาด: Wipe the cuff and manometer with a soft cloth dampened with a mild disinfectant solution. Do not immerse any part of the device in water.
• พื้นที่จัดเก็บ: Store the device in its leatherette zippered carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
• Filter Screen Valves: The sphygmomanometer features filter screen valves to reduce dust buildup. These help ensure proper and efficient operation by capturing particles as air travels through the tubing. No user maintenance is typically required for these filters.
• การสอบเทียบ: Aneroid sphygmomanometers should be checked for calibration periodically, typically every 1-2 years, or if accuracy is suspected. Consult a qualified technician for calibration services.

7 การแก้ไขปัญหา

If you encounter issues with your sphygmomanometer, consider the following:

• การอ่านค่าที่ไม่ถูกต้อง: Ensure correct cuff size and proper placement. Verify the air-release valve is fully closed during inflation. Consider professional calibration if readings remain inconsistent.
• ปลอกแขนไม่พองตัว: Check all tubing connections for tightness. Ensure the air-release valve is fully closed. Inspect the bulb and tubing for any visible damage or leaks.
• Cuff Deflates Too Quickly: Ensure the air-release valve is not open too wide. Check for leaks in the cuff, tubing, or bulb.

For persistent issues, contact McKesson customer support or a qualified medical equipment technician.
