Abstract: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.
