在台式血压计的检定工作中,笔者发现血压计返修率高,最常见的原因就是血压计贮汞瓶内部杂质污染。因为这些杂质的存在,在测量血压的过程中,就会出现玻璃管内水银不断冒泡、断柱或隐蔽性断柱等现象,影响测量值的准确,产生测量误差。解决此问题的方法通常是彻底清洁贮汞瓶。但如何清洁呢?通常的方法是把水银倒出贮汞瓶后,用有
In the test of the desktop sphygmomanometer, the author found that the sphygmomanometer repair rate is high, the most common reason is the sphygmomanometer mercury contamination inside the bottle. Because of the presence of these impurities, the process of measuring blood pressure, there will be continuous bubbling of mercury in the glass tube, broken column or hidden broken column phenomenon, affecting the measurement accuracy, resulting in measurement error. The solution to this problem is usually to clean the mercury cylinder. But how to clean it? The usual method is to use mercury after pouring out of mercury storage bottle
