医疗设备系统性故障的认知和处理

当医疗设备发生故障时,我们要分清引起故障的原因,根据原因找出故障源,根据故障源,判断出该故障是医疗设备的系统性故障(即是由于医疗设备原先的设计、制造工艺、操作程序或其他关联因素引起的,以特定形式出现的故障),还是偶然性故障.如果是系统性故障,即使是在保修期外的,在维修费用方面,我们要与厂家据理力争,积极维护医院的利益,尽量减少经济损失,提高医疗设备的经济和社会效益.     

X光机常见故障的检修与体会

对设备的任何部分进行维修前，必须认真阅读有关图纸资料，弄明白它的工作原理，要进行修理的这一部分的结构情况，不可盲目修理，否则易引起设备的一个故障未排除，又出现新的故障。常见的有外观法、通电法、电流法、电阻法、电压法、分块短路法、信号源法、示波器寻迹法、扫频仪检测法、和换板替代法。一般的常见故障：诸如保险丝熔断、电源插座接触不良等。通电的状态下，切忌用电烙铁或起子接触电路板，

AMI－ 7500型监护仪的故障与修理

AMI－ 7500监护仪具有体积小、重量轻、操作简单等特点。我院手术室有两台该型号监护仪,用于手术患者的监护,在几年的使用中出现了一些故障,现将这些故障的修理介绍如下。 故障现象 1 血氧饱和度测量时好时坏。 故障修理观察血氧饱和度的光电传感器,发现血氧饱和度测量的时好时坏与光电传感器红发光二极管是否发光有关,发光时测量正常,不发光时不显示测量数字、仪器报警。 分析原因有二, (1)电缆内部有断线、插头插座接触不良或脱焊; (2)驱动红发光二极管的电路有故障。拆开仪器上盖,测量 J15插座 3－ 1脚之间直流电压,红光二极管发光时为 0.66V,不发光时为 3.3V,说明红发光二极管驱动电路无故障,接触不良故障应在 J15至光电传感器之间,逐段轻轻扯动联接电缆,最终找到断线部位,用手术刀小心将电缆保护层破开,发现一根白色导线断,重新焊接,再用绝缘胶布粘好涂上硅胶,此时血氧饱和度测量恢复正常。

螺旋CT(SOMATOM plus4)的使用及维护体会

螺旋ＣＴ是最先进的医疗设备之一 ,它是集Ｘ线发生、电子计算机技术、滑环技术、冷却技术等高科技于一体的大型医疗设备。由于其结构复杂 ,涉及技术领域较多 ,目前国内绝大多ＣＴ的维修仅限于卖方的工程人员 ,再加上国外大公司的技术和零配件的垄断 ,国内又无专门的培训机构 ,使得国内在医院从事ＣＴ维护的技术人员倍感吃力。笔者认为 ,大家经常交流各自的维护经验对提高一般故障的处理能力是很有必要的。我院于 1997年底购进德国西门子ＳＯＭＡＴＯＭ Ｐｌｕｓ4螺旋ＣＴ 1台 ,经过近 5年来的实际操作和维护记录总结 ,积累了一定的经验 ,以…

猪肺磷脂注射液联合经鼻持续气道正压通气对呼吸衰竭早产儿的临床疗效及肌酸激酶同工酶活性的影响

目的 探讨猪肺磷脂注射液联合经鼻持续气道正压通气(NCPAP)对呼吸衰竭早产儿的临床疗效及肌酸激酶同工酶活性(CK-MB)的影响.方法 选取呼吸衰竭早产儿80例,分为观察组和对照组各40例.对照组采用NCPAP给氧治疗,观察组给予NCPAP给氧联合猪肺磷脂气管内给药.观察两组患儿治疗前及治疗12h、24 h后PaO2、PaCO2、血氧饱和度(SaO2)、pH的变化情况,检测治疗前及治疗5d后血清CK-MB水平;评估两组患儿的临床治疗效果.结果 两组患儿PaO2、PaCO2、SaO2、pH比较,差异均有统计学意义(P＜0.05),其中观察组治疗后的PaO2、SaO2、pH均高于对照组,PaCO2则低于对照组.两组的PaO2、SaO2、pH均随观察时间延长而升高(P＜0.05),PaCO2均随观察时间的延长而降低(P＜0.05).观察组治疗有效率为87.5％,显著高于对照组的70.0％ (P ＜0.05).治疗5d后两组患儿血清CK-MB水平均较前降低(P＜0.05),且观察组明显低于对照组(P＜0.05).结论 猪肺磷脂注射液气管内给药联合NCPAP可以显著降低呼吸衰竭早产儿CK-MB的含量,提高治疗有效率,起到很好的呼吸循环支持作用.     

Survey and practice of reporting quality of randomized controlled clinical trials on traditional Chinese medicine

Evidence obtained from randomized controlled trials （RCTs） has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine （TCM） and results have shown that there is an urgent need for higher quality RCTs on TCM.     

TCM Treatment of Ankylosing Spondylitis by Tonifying the Kidney and Strengthening the Governor Vessel

Ankylosing spondylitis is a chronic and progressive disorder with inflammation mainly involving the central axis joints. It mainly affects the cervical spine and the lumbosacral area, with the pathogenesis closely related to the kidney and the Governor Vessel (GV). TCM holds that the syndrome is deficiency in origin and excess in superficiality, which is due to insufficiency of the kidney, deficiency of GV, and blocking of the channels with the invasion of exogenous evil, leading to poor circulation of qi and blood and malnutrition of the bones, muscles and joints. The TCM method of tonifying the kidney and strengthening GV to regulate circulation of qi and blood and check the arthralgia pain should be adopted, with the Kidney-Tonifying and GV Strengthening Decoction (益肾强督汤) prescribed.
