Electrical Safety Test Lab Report

OBJECTIVE

1. To learn the ways to perform electrical safety test on medical devices.

INTRODUCTION

Medical devices are referred to a wide range of instrument which important for the diagnostic, monitoring and therapeutic of patients. Medical devices can be as simple as tongue depressors or as complicated as haemodialysis machines. Medical device also can be categorized in to electrical and non-electrical devices.

The increasing usage and complexity of electrical medical devices have more than 10000 electrocutions cases annually. Thus, electrical safety test is an important parameter to ensure that all electrical devices are following the standards safety operating guidelines in order to protect patients from electrocuted. Several safety

The electrical devices have to pass every single safety test in order to obtain certification from the safety agency in respective region. The tests are according to the international standards. For example, the standards which involved are IEC60601, IEC60335 and IEC61010. Generally, the procedures of the tests included test for patient leakage current, earth leakage current, and enclosure leakage current.

Medical devices can be further categorized into three classes and three types. The three classification of medical devices are Class I, Class II and Class III, while the three types of medical devices are Type B, Type BF and Type CF. Each classes and types of medical device have different safety certification which take in different safety standards.

Operators are required to know classification and types of the medical device they are operating to ensure the safety of the

Different mode of operation will have different benefit. By using automatic mode, we can get the value without much time wasting, while using manual mode, we can choose the certain parameters to be printed as the final result to avoid overloaded data which is unnecessary.

From table 1, we able to observe that the measured values of the Body Composition Analyser in the lab are lower than the maximum allowable value stated in the IEC601-1 Standard. Thus, the BoCA in the lab is classified as safe device since it fulfil the parameter in the IEC601-1 Standard. However, if other safety measure is not taken, this device will also cause harm to the
