Product: A fundamental medical device for measuring blood pressure. It consists of an inflatable cuff, a manual squeeze bulb, and a mechanical gauge (typically an aneroid or mercury manometer).
Working Principle:
1.The cuff is inflated around the upper arm to temporarily restrict blood flow.
2.Pressure is then slowly released from the cuff.
3.During deflation, healthcare professionals auscultate the brachial artery using a stethoscope.
4.The appearance and disappearance of specific sounds (Korotkoff sounds) indicate systolic and diastolic pressure readings.
Key Features: Renowned for its accuracy, reliability, and independence from electrical power. Although requiring trained proficiency for correct operation, it remains the clinical gold standard for precise blood pressure measurement.
