一、血压计的故障分析及排除1.零位:当打开血压计后(打开水银壶开关),首先观察水银是否在零位刻度线,不在则水银不足,需要补加水银。2.漏气:打气后先将橡胶袋至测压计之间的橡胶管折起压紧(将橡胶袋缠绕在圆柱体上),如果水银柱面自动下降较快,则说明测压计漏气。先检查橡胶管是否老化或破裂,与水银壶嘴连接处是否紧密,这是 First, the sphygmomanometer failure analysis and exclusion 1. Zero: When the open sphygmomanometer (open the mercury kettle switch), first observe whether the zero mark in the mercury line, not in the lack of mercury, the need for additional mercury. 2. Leak: After cheer up the rubber bag to the pressure gauge between the rubber tube folded up (the rubber bag wrapped around the cylinder), if the mercury cylinder automatically drop faster, then the piezometer leak gas. First check whether the rubber tube aging or rupture, and mercury spout connection is close, this is
