国产 ND82—B 型脑电图机,其墨水泵均以单缸的形式,排列固定在描笔尾部的板面上,因墨水泵与描笔的结合部长年浸泡在墨水内。容易腐蚀,断裂,脱焊,使缸内墨水经常向外面渗出,墨水随着机板面的接合裂隙进入机器内部、使机内部的主要零件生锈,霉烂,引起记录器、电容等损坏。加上单缸的排列间距较小,不易清除卫生、机面不能保持清洁。而且,描记作图的过程中,由于单缸的位置较低、压力小,常常造成墨水停供、描不出波形。为了解决上述问题,
Domestic ND82-B type EEG machine, the ink pumps are in the form of a single cylinder, arranged in the pen tail board surface, ink pump and stylus for many years immersion in ink. Easy to corrode, rupture, desoldering, so that the ink inside the cylinder often seepage to the outside, ink with the board surface into the cracks within the machine, so that the internal parts of the main rusty, mildew, causing damage to the recorder, capacitors and so on. With single cylinder arrangement spacing is small, not easy to clean, machine can not be kept clean. Moreover, tracing the process of mapping, due to the lower position of a single cylinder, the pressure is small, often causing the ink stopped, can not describe the waveform. In order to solve the above problem,
