血糖仪的正确使用方法

Edit date:2026-07-27

血糖仪是监测血糖水平的便捷工具,正确使用能帮助了解日常血糖变化,但操作不当可能影响结果准确性。掌握基本使用原则能让测量更可靠。

 

器械选择:

选择血糖仪时需关注以下几个关键点:准确性:优先选择误差范围较小的型号,通常包装或说明书会标注“误差不超过±15%”,这意味着实测值和真实值差距较小。操作便利性:老年人或手部活动不便者,可考虑屏幕大、按键少、试纸自动吸入的款式。试纸匹配性:部分血糖仪需搭配特定型号试纸,购买时需确认两者匹配,避免买错导致无法使用。认证标识:查看包装是否带有“医疗器械注册证号”,可在国家药监局官网查询真伪。

 

用前准备:

使用前需清洁双手并擦干,残留水分或污渍可能污染试纸。打开试纸瓶后需立即取出试纸,避免暴露在空气中过久受潮。首次使用或更换试纸批次时,需用仪器自带的校准芯片或手动输入试纸代码,确保仪器识别正确。采血针需根据皮肤厚度调节扎针深度,通常儿童或皮肤薄者选择1-2档,成年人选择3-4档。

 

使用说明:

正确操作分为四个步骤:采血:用酒精棉片消毒指尖两侧(痛感较轻),待酒精完全挥发后扎针,轻轻挤压指腹获取一滴血。滴血:将血滴自然接触试纸采样区,不可涂抹或反复按压,血量不足会导致显示“错误”。读取结果:插入试纸后再开机,或开机后立即插入试纸,等待5-10秒显示数值。记录数据:测量后记录时间和结果,部分仪器可自动存储数据或连接手机同步。
