维修方法一、提高灵敏度灵敏度差的原因,一般都为玻管帽内和水银瓶内滤片(油毡)毛细孔、通气孔及开关孔芯被污物阻塞。检修方法如下: ①血压计向右倾斜45°,使水银全部回入水银瓶内,扳起装有空气过滤器的压板或旋松玻管帽,把玻管放在玻管压板上压紧,使之脱离空气过滤器。将汞柱升至刻度中段后,停止打气,如汞柱仍缓慢上升,则水银瓶内毛毡通气不畅,应予调换。
Maintenance methods First, to improve the sensitivity of the reasons for poor sensitivity, are generally glass tube cap and mercury bottle filter (linoleum) pores, ventilation holes and the switch core is blocked by dirt. Maintenance methods are as follows: ① sphygmomanometer tilt 45 ° to the right, so that all mercury back into the mercury bottle, hold the plate with air filter or unscrew the glass tube cap, the tube on the glass tube platen pressed, Remove it from the air filter. Mercury column to the middle of the scale, stop cheering, such as mercury column is still slowly rising, the poor ventilation of the bottle of mercury, should be replaced.
