上海产ND-82B型脑电图机,在国内县(团)级以下医院装备较普及。该机的记录笔槽是用不锈钢片制成的,其主要缺点是:机器停用时,若将记录笔置于笔槽内或记录面板上,由于笔尖与接触面接触不严密,墨水就会经笔尖溢出笔外,甚至流入其它部件,造成不良后果;若将记录笔抬起(悬空),由于记录笔不在功能位 Shanghai-produced ND-82B electroencephalography equipment has become more popular in hospitals below the national county (group) level. The recording pen groove of this machine is made of stainless steel sheet. Its main disadvantage is that when the machine is disabled, if the pen is placed in the pen tray or on the recording panel, the ink will come into contact with the contact surface due to the tight contact between the pen tip and the contact surface. After the pen overflows the pen, it may even flow into other parts, causing adverse consequences; if the pen is lifted (floating), the pen is not in the function position.
