CPHT(周期性压力保持测试=Cycle Pressure Holding Test)
After closing V24 and V24B and opening the V26 the machine will check thecompliance of the hydraulic. 关闭V24和V24B后,打开V26机器将检查水路 1. Compliance check: 一致性检测 After the start of the CPHT the UF pumpwill do 1 stroke 开始CPHT测试之后超滤泵动作一次 à if the pressure change is < 50 mmHg the UF pumpwill do one more stroke à如果压力变化值< 50 mmHg 超滤泵将会做更多次动作 à from the dialysate pressure change the machine cancalculate the compliance of the hydraulic, that means if there is a Diasafefilter is installed or two Diasafe filters in case ofOnline Plus etc. à从析液压力改变机器可以计算水路一致性,如果有一个或两个Diasafe过滤器安装Diasafe过滤器的Online Plus等等 à if after the second stroke of the pump the pressurechange is still < 50 mmHg (in case of a leakage, air in the system or wrong pressure measurement à如果超滤泵第二次动作之后,压力改变依然< 50 mmHg(假设有泄漏,系统进空气,或者压力传感器测量错误) à CyclicPHT F01will occur
à将会出现Cyclic PHT F01错误 (1). Too much air in the filters(Diasafe/ Onlineplus) e.g. after filter change 太多的空气在过滤器中(Diasafe/ Onlineplus)等。填充过滤器 (2). Too much air in thesecondary air separator (e.g. ASP malfunction). Check protective earthresistance at the socket. 太多空气在二次空气分离器中(例如:ASP泵故障)。检查插座到机器的安全接地线接地线电阻 (3). Leakage on V 24/ 24b/ 26/43/ dialysate pressure transducer/ relief valve 电磁阀V24/V24B/V26/V43泄漏,透析液安全调压阀(78阀)泄漏。 (4). The system used includes the Diasafe option--> Yes --> Is the Diasafe test being performed --> No --> CPU2/array 2/ DIP switch 1 must be set to ON in any case. 机器使用Diasafe选项--> Yes ->Diasafe测试被执行--> No-> CPU2/ array 2/ DIP switch 1 无论如何必须设置为 ON (5). ASP leaky ASP泵泄漏 (6). Erroroccurs occasionally in relation to the flow without any reason. (Solution: useSW 4.50H/S) 错误偶尔出现与流没有任何关系(解决方案:使用软件版本4.50H/S) It's similar to the UFK calculation of the dialyser and automaticsetting of the TMP limits 类似于UFK计算透析器和自动设置TMP界限 à at thebeginning of a treatment the machine will check the dialysate pressure (9)after every UF pump stroke: à在每次超滤泵冲程之后,机器开始治疗时将检查透析液压力传感器(9) à if thepressure is very low and the change is quite small --> it must be a highflux dialyser (big UFK) and the alarm limits are set very small 如果压力很低,变化很小--> 它必须是一个高通量透析器(大超滤细数)和设置报警范围很小 à if thepressure is higher and the change per stroke is bigger --> it must be a lowflux dialyser (small UFK) and the alarm limits are set bigger. 如果压力很高变化很大--> 它必须是一个低通量透析器(小超滤细数)和设置报警范围很大
2. After thecompliance check the machine will calculate the expected balancing error: 合规检查后机器将计算预期的平衡错误: The pressure value measured bytransducer 9 should be quite stable 被9号压力传感器检测得的压力值应该是相当稳定的 à if thepressure is not stable (in case of a leakage) 如果压力不稳定(万一发生泄漏)的情况下 à CyclicPHT F02will occur (calculated balancing error > ± 125 ml/h) 将会出现Cyclic PHTF02错误报警(平衡计算错误> ± 125 ml/h) (注:可设置LP632-1-5 on,机器在模拟透析下,每2分钟测试一次CPHT,并且显示当前balancing error XX ml/h,可更直观的判断。)
3. While the machine will start to calculate thebalancing error the CPU 2 changes the setting of the measuring range (operatingpoint) on CPU 2. 而机器将开始计算平衡错误CPU 2改变测量范围的设置(操作点) 在CPU2中。 The resolution of the dialysate pressure measurementmust be higher during CPHT 透析液压力测量CPHT的频率期间必须更高 à thecalculation must be done with a higher resolution 计算必须用更高的分辨率 à if thefluctuation of the pressure is too high 如果压力太高的波动 à CyclicPHT F03 will occur 将会出现Cyclic PHT F03错误 ·DAC converter (IC11) on P.C.B. LP632 defective DAC转换器(IC11)P.C.B. LP632缺陷 · Operational amplifier (IC1/IC3) on P.C.B. LP632 defective 运算放大器(IC1 / IC3)P.C.B. LP632缺陷 · Acknowledgement (P_DIAL, X633L/ B6) -> X632/A29 defective 确认(P_DIAL X633L / B6)- > X632 / A29缺陷
4. The cyclic pressureholding test could not be completed or performed even after a maximum testdelay of 180s. 周期性压力保持测试无法完成或保持测试执行超过180秒钟的最大测试延迟。 à CyclicPHT F04will occur Cyclic PHTF04将会出现 ·Fill program in progress (check protective conductorresistance at receptacle) 填充程序正在执行(检查废液腔中的阻抗探测器6是否正确) · Blood alarm 血报警 · V43 open (e.g. TMP alarm) V43打开(如:TPM报警) · Air separation pump active 空气分离泵开始激活动作 · Flow alarm 流量报警 · Flow fluctuations >±180ml/min 流量波动>±180ml/min
