255);"><span style="font-family:Verdana;overflow-wrap: break-word;">在使用金宝血液透析机AK95S对病人实施血液透析当中，血线报警是经常卅现的一类故障，现结合实战经验对此类故障谈谈心得：</span></p><p style="overflow-wrap: break-word;color: rgb(68, 68, 68);font-family: Tahoma, "Microsoft Yahei", Simsun;font-size: 14px;text-align: start;white-space: normal;background-color: rgb(255, 255, 255);"><span style="font-family:Verdana;overflow-wrap: break-word;"><br style="overflow-wrap: break-word;" />1 故障现象<br style="overflow-wrap: break-word;" />血线灯点亮成红色，故障报警灯亮起，声音报警急促，血泵停止。<br style="overflow-wrap: break-word;" />2 故障代码<br style="overflow-wrap: break-word;" />C COFB 088 042；C COFB 088 043；C COFB 088 044；C COFB 088 045；C COFB 088 046；C COFB 088 047；C COFB 088 048；C COFB 088 049。其中以C COFB 088 048最为常见。</span></p><p style="overflow-wrap: break-word;color: rgb(68, 68, 68);font-family: Tahoma, "Microsoft Yahei", Simsun;font-size: 14px;text-align: start;white-space: normal;background-color: rgb(255, 255, 255);"><span style="font-family:Verdana;overflow-wrap: break-word;"><br style="overflow-wrap: break-word;" />3 原理分析<br style="overflow-wrap: break-word;" />血线探测器的原理是对红外线进行探测，也就是通过计算接收到红外线强度的大小来判断血路中是否有漏血，实际电路中就是有一个红外发光二极管提供红外线，通过两段透明的管道，让光线穿过其间夹着的血路，然后到达红外接收管，检测到的光信号会转换成电信号，通过后续的转换电路会送到电脑芯片参与计算，与电脑中存储的数据进行比较，然后做出相应判断。</span></p><p style="overflow-wrap: break-word;color: rgb(68, 68, 68);font-family: Tahoma, "Microsoft Yahei", Simsun;font-size: 14px;text-align: start;white-space: normal;background-color: rgb(255, 255, 255);"><span style="font-family:Verdana;overflow-wrap: break-word;"><br /></span></p><p style="overflow-wrap: break-word;color: rgb(68, 68, 68);font-family: Tahoma, "Microsoft Yahei", Simsun;font-size: 14px;text-align: start;white-space: normal;background-color: rgb(255, 255, 255);"><span style="font-family:Verdana;overflow-wrap: break-word;">4 故障排除<br style="overflow-wrap: break-word;" />4．1 硬件处理：用酒精棉签或蘸清水擦拭 线探测器表面，去除可能附着的盐水或血液留下的脏污，开机，如果不再报警，则进入调校程序进行校准；如果还报警，则需要关闭机器，打开机器上面的盖子，拔下探测电路的插头，把探测电路拆下来，对发射管和接收管进行清清，对光路传输的两段透明管路的表面进行清洁，然后装好机器，开机，进入调校程序校准，大多数故障经过这样处理就会得到解决，然后机器正常运转。极少数情况下，这样处理后还不能排除故障，那么存在的原因则是：① 电路板本身存在脏污，则用无水酒精去除；②发光管能量不足或损坏，则更换发光二极管；③接收管故障，更换接收管；④ 其他可能存在的故障，则只有联系服务商了。</span></p><p style="overflow-wrap: break-word;color: rgb(68, 68, 68);font-family: Tahoma, "Microsoft Yahei", Simsun;font-size: 14px;text-align: start;white-space: normal;background-color: rgb(255, 255, 255);"><span style="font-family:Verdana;overflow-wrap: break-word;"><br style="overflow-wrap: break-word;" />4．2 程序校准：在显示窗口处于暗的状态时，同时按压操作面板上方中间两个没有标识的键(暗键)和左下角的确定(箭头)键，3—5秒后，显示窗亮起，通过调节SET旋钮选至Service／Preset，按“确定”进入，在40秒内输入机器维修代码(58，96，44或16，90，00)，选择Service后按“确定”进入，再选择Calib进入，选择Transd，然后选Extem进入，通过旋转SET旋钮找到PRIMING DETECTOR，按确定键，把提前准备好的干净透明的透析管路插入探测器后，按确定键，等待2—3分钟，机器会自行检测并计算数据，存储入EEPROM，然后提示按“HOLD”键退出，再按“HOLD”三次，退至SELECT SERVICR MODE选EXIT后进入MAINTENANCE SELECTION，选Fch按确定键进入机器自检。至此，完成程序校准。</span></p><p style="overflow-wrap: break-word;color: rgb(68, 68, 68);font-family: Tahoma, "Microsoft Yahei", Simsun;font-size: 14px;text-align: start;white-space: normal;background-color: rgb(255, 255, 255);"><span style="font-family:Verdana;overflow-wrap: break-word;"><br style="overflow-wrap: break-word;" />5 小结<br style="overflow-wrap: break-word;" />由于血液透析机工作环境和用于血液透析这一工作性质，不可避免的处于相对潮湿、极易受到盐水或血液污染的状况，因而血线探测故障就显得比较多，按照上述方法处理，排除机器故障，消除机器报警是快速、有效的。</span></p><p style="overflow-wrap: break-word;color: rgb(68, 68, 68);font-family: Tahoma, "Microsoft
