浮标式氧吸入器流量计检定分析数据
收藏资源简介：
浮标式氧气吸入器是广泛应用风险较高的医疗器械。检定分析得出的结果来判断浮标式氧吸入器流量计是否符合流量计检定要求，有助于判断市场上浮标式氧气吸入器的的整体质量，为政府监管、医疗单位购买提供参考和技术支撑。1数据采集：名称、型号、送检单位、编号、流量调节范围检查、最大量程范围、按照浮标式氧气吸入器计量检定规程要求测得的3个流量点被检流量计示值等；2数据处理：(1)流量点示值误差=(流量点标准流量计示值-流量点标准流量计示值)/最大量程范围；(2)被检流量计示值误差，为3个流量点示值误差最大值；(3)是否符合流量计检定要求，规程要求流量调节范围检查为符合、流量计示值误差为±4%，当流量调节范围、流量计示值误差流量计示值误差都符合要求的为符合，反之为不符合；3其他说明：流量点标准流量计示值为检定流量点流量值。
Float-type oxygen inhalers are widely used high-risk medical devices. The results obtained through verification and analysis are used to determine whether the flowmeters of float-type oxygen inhalers meet flowmeter verification requirements, which helps evaluate the overall quality of float-type oxygen inhalers on the market and provides reference and technical support for government supervision and medical institution procurement. 1. Data Collection: Name, model, inspection-submitting unit, serial number, flow regulation range inspection, maximum measuring range, measured readings of the flowmeter under test at three flow points obtained in accordance with the metrological verification regulation for float-type oxygen inhalers, etc. 2. Data Processing: (1) Flow point indication error = (standard flowmeter reading at the flow point - reading of the flowmeter under test at the flow point) / maximum measuring range; (2) The indication error of the flowmeter under test is the maximum value of the indication errors of the three flow points; (3) Compliance with flowmeter verification requirements: The regulation stipulates that the flow regulation range inspection must pass, and the flowmeter indication error must be within ±4%. A product is deemed compliant only if both the flow regulation range and the flowmeter indication error meet the specified requirements; otherwise, it is deemed non-compliant. 3. Other Notes: The standard flowmeter reading at a flow point refers to the flow value of the verification flow point.
