style="color: rgb(83, 118, 105);font-size: 15px;line-height: 2;letter-spacing: 1px;padding-right: 6px;padding-left: 6px;box-sizing: border-box;"><p style="text-indent: 2em;white-space: normal;box-sizing: border-box;"><span style="font-size: 16px;box-sizing: border-box;">水银血压计使用方便,测量准确,可是有时候也会故障了,真麻烦呢!水银血压计坏了怎么修?常见的几种故障是哪些呢?</span></p><p style="text-indent: 2em;white-space: normal;box-sizing: border-box;"><span style="font-size: 16px;box-sizing: border-box;">其实,水银血压计坏了也不用着急,简单几招可以帮你把水银血压计变回正常。常见故障类型及其维修方法详见下文。</span></p><p style="text-indent: 2em;white-space: normal;box-sizing: border-box;"><span style="font-size: 16px;box-sizing: border-box;">第一种,漏水银。血压计应该在使用后应将其倾斜45度以上,使水银返流回贮汞瓶中后再合上开关,将水银关闭在贮汞瓶中。如果水银血压计漏水银了,用一个带针头的注射器,从备用水银中吸适量的水银后,开足血压计上盖,打开贮汞瓶开关,将针头从玻璃管上端压片上的小孔插入,渐渐注入水银,并轻轻振动血压计,使注入的水银和从贮汞瓶中涌出的水银融合,注入水银的量以满足零位误差的要求为准,应选用小口径针头,以避免损坏过滤片。</span></p><p style="text-indent: 2em;white-space: normal;box-sizing: border-box;"><span style="font-size: 16px;box-sizing: border-box;">第二种,胶垫堵塞。维修方法是用一根针刺穿玻璃管上端压片上橡胶垫即可。</span></p><p style="text-indent: 2em;white-space: normal;box-sizing: border-box;"><span style="font-size: 16px;box-sizing: border-box;">第三种,气路漏气。在加压后,分别折叠压紧从橡胶球到贮汞瓶间以及从贮汞瓶到臂带气囊间的橡胶管,观察水银是否继续下降,逐段排除查找出漏气的部位。若为橡胶袋漏气,应予以更换;若为橡胶球单元漏气,应检查球尾的单向阀或排气阀门是否漏气,否则也应更换;若是橡胶气门漏气,可将橡胶球从排气阀处拆分开:螺丝扣旋紧式的,拧开后就可以看到一小段类似自行车轮胎气门芯的橡胶管;拨除式的,摘掉皮球后,也可从排气阀门中取出这样的一段气门芯,用手指搓动这个橡胶管,可以发现其两侧各有一裂隙,假如裂隙中有毛絮填塞,加压中,松开皮球时,裂隙不能闭合,刚打上去的水银柱就会又下来。清理裂隙中的脏物,由此引起的漏气问题就可被排除。</span></p><p style="text-indent: 2em;white-space: normal;box-sizing: border-box;"><span style="font-size: 16px;box-sizing: border-box;">第四种,内壁污物。将玻璃管卸下,将一根长细铁丝一端拧上小棉球,另一端穿出玻璃管,牵拉棉球擦拭玻璃管内壁,如遇顽渍可以蘸适量酒精。应注重在清洁时带上口罩避免吸入黑色的氧化汞粉末。</span></p><p style="text-indent: 2em;white-space: normal;box-sizing: border-box;"><span style="font-size: 16px;box-sizing: border-box;">水银血压计质量好,耐用实用,只要小心使用,水银血压计便不容易故障。</span></p></section></section></section></section><section style="text-align: center;opacity: 0.35;margin-right:
