无创测量血压计检定装置
收藏资源简介：
本装置主要由标准压力计、血压模拟器、秒表、硬质金属容器组成，适用于示波法、听诊法原理的台式血压计、血压表、电子血压计及血压监护仪等无创血压计的检定。根据JJG 692-2010无创自动测量血压计及JJG 270-2008 血压计和血压表检定规程，血压计的检定方法采用比较法，分为静态和动态两部分。动态检定是指对示波法原理的血压计进行示值重复性检定，方法为用胶管和三通把血压计、袖带与血压模拟器相串接，采用外置袖带模式并选择适当的血压值和脉率，由血压计对血压模拟器加压测量，以确定血压计显示的收缩压和舒张压的示值重复性。静态检定是指用标准压力计与被检血压计、三通、硬质金属容器及手动加压泵相连，构成静态压力检定系统，通过加压泵达到预定压力值，通过比较确定被检血压计的示值误差。
This device mainly consists of a standard manometer, blood pressure simulator, stopwatch, and rigid metal container. It is suitable for the verification of non-invasive sphygmomanometers including desktop sphygmomanometers, blood pressure gauges, electronic sphygmomanometers and blood pressure monitors based on the oscillometric and auscultatory principles. According to JJG 692-2010 Verification Regulation for Non-invasive Automatic Blood Pressure Measuring Instruments and JJG 270-2008 Verification Regulation for Sphygmomanometers and Blood Pressure Gauges, the verification method for sphygmomanometers adopts the comparison method, which is divided into static and dynamic parts. Dynamic verification refers to the verification of indication repeatability for sphygmomanometers based on the oscillometric principle. The specific procedure is to connect the sphygmomanometer, cuff and blood pressure simulator in series with rubber tubes and three-way connectors, adopt the external cuff mode, select appropriate blood pressure values and pulse rates, and conduct pressurized measurement on the blood pressure simulator via the tested sphygmomanometer to determine the indication repeatability of systolic and diastolic blood pressure displayed by the device. Static verification refers to forming a static pressure verification system by connecting the standard manometer, the sphygmomanometer to be verified, three-way connectors, rigid metal containers and a manual pressure pump. The pressure pump is used to reach the preset pressure value, and the indication error of the sphygmomanometer under verification is determined through comparison.
