口腔综合治疗机电气安全的检测与质量控制

Inspection and Quality Control of Electrical Safety for the Oral Comprehensive Treatment Machine

目的检测口腔综合治疗机所存在的电气安全隐患,提高其安全性能和医护人员、患者的安全系数。方法采用奥利克288型电气安全检测仪,按照检测规范要求对我院综合科、牙体科、修复科以及儿童齿科4个科室共计100张椅位进行电气安全检测,检测项目主要包括外壳漏电流、患者漏电流、对地绝缘阻抗等6项指标。结果最终检测结果显示,不合格的指标主要是电源线接头氧化,以及治疗机地箱内湿度过大引起的。结论通过检测使我们意识到口腔综合治疗机在其特殊的环境下也存在不安全因素,应该对其各项指标进行定期检测,并纳入常态化管理,这也是医院设备质量控制体系中的重要环节。

Objective To inspect the security problems for the oral comprehensive treatment machine so as to enhance its safety performance as well as the safety coefficient for medical personnel and patients.Methods With application of Ehrlich 288 type electrical safety testing instrument,the electrical safety testing was performed for 100 chair positions according to the examination standard requirement of 4 departments in the hospital,including General Department,Department of Endodontics,Department of Prosthodontics and Department of Children’ Dental.The testing project mainly included 6 indexes such as casing leakage current,patient leakage current and the insulation impedance.Results The final test results showed that the main index of the non-conformity was the oxidation of the power line and the over humidity in the treatment machine.Conclusion Through the testing,it had been realized that unsafe factors also existed in the oral treatment machine in special environment.Hence,regular detection of its indicators should be done and incorporated into the normal management,which also served as an important part in the hospital equipment quality control system.
