Electromagnetic interference (EMI) with electronic medical equipment induced by automatic conveyance systems is estimated. We measured the electric intensities of electromagnetic waves transmitted by three self-controlled electric truck systems. We also observed EMI with an infusion pump and a syringe pump set 1 m from the rail. The maximum electric field intensity was observed at the supplied current frequency in two systems with non-contact power supply mechanisms. The highest value, 137.0 dBV/m, was measured just beside the rail. This is higher than the international electromagnetic immunity standard limit for electronic medical equipment. EMI may occur if electronic medical equipment is used within 2 m of the rail when the system contains an inductive power supply mechanism. With a contact power supply mechanism, the electric field intensity was much lower than that of the immunity standard. EMI should not occur even when electronic medical equipment is used just beside the rail. 相似文献

Problems involving electromagnetic interference (EMI) with electronic medical equipment are well-documented. However, no systematic investigation of EMI has been done. We have systematically investigated the causes of EMI. The factors involved in EMI were determined as follows: 1) Electric-field intensity induced by invasive radio waves from outside a hospital. 2) Residual magnetic-flux density at welding points in a building. 3) Electric-field intensity induced by conveyance systems with a linear motor. 4) The shielding capacity of hospital walls. 5) The shielding capacity of commercial shields against a wide range frequency radio waves. 6) The immunity of electronic medical equipment. 7) EMI by cellular telephone and personal handy-phone system handsets.From the results of our investigation, we developed a following practical procedure to prevent EMI. 1) Measurement of electric-field intensity induced by invasive radio waves from outside the hospital and industrial systems in the hospital. 2) Measurement of residual magnetic-flux density at electric welding points of hospital buildings with steel frame structures. 3) Control of the electromagnetic environment by utilizing the shielding capacity of walls. 4) Measurement of the immunity of electronic medical equipment. And 5) Installation of electronic gate equipment at the building entrance to screen for handsets. 相似文献

利用医院信息标准规范电子病案 总被引:1,自引:1,他引:1
目的探讨利用医院信息标准化,指导电子病案标准化。方法文献查阅法结合个人总结。结果归纳出与电子病案发展相关的标准如HL7医院电子信息交换标准、医学数字化影像通信标准DICOM、SNOMED编码、国际疾病分类、ASTM制定的有关医疗标准、NDC国家药品编码、统一的医学语言系统等,对电子病案发展提供了规范化和标准化依据。结论我国医院信息标准化可借鉴发达国家医院信息标准化,在相对成熟的医院信息标准的基础上结合本国医院信息的现状制定出适合我国医院信息标准,加快电子病案的发展,解决电子病案在标准化方面的瓶颈问题,更有效地为临床、教学、研究、管理服务。 相似文献

发生医疗诉讼,对医院及有关涉案专家的声誉和形象都会产生若干负面影响.我们必须时刻把严抓医疗质量和医德医风建设放在医院建设的首位,从医院自身入手,尽量减少医患纠纷及医疗诉讼.要加强对客户供应产品特别是药品和卫材的管制,加强时非本院人员如进修医生护士、实习医生护士、陪工等的管理,严格监督和检查,以保证诊疗质量.医患纠纷发生后,应当采取积极的态度,寻求双方的和解,争取患者及家属的认同,进而得到舆论的认同. 相似文献
