Sphygmomanometer

A sphygmomanometer (/ˌsfɪɡmoʊməˈnɒmɪtər/ SFIG-moh-mə-NO-mi-tər), a.k.a. a blood pressure monitor, or blood pressure gauge, is a device used to measure blood pressure, composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner,[1] and a mercury or aneroid manometer to measure the pressure. Manual sphygmomanometers are used with a stethoscope when using the auscultatory technique.
