Servicing clinical computing equipment
Overview
This standard identifies the competencies you need to carry out servicing activities on clinical computing equipment, in accordance with approved procedures. You will be required to service a range of clinical computing equipment including computerised medical devices, medical devices connected to computers, computers which host medical device software and associated equipment. This will involve dismantling, removing and replacing faulty items, at component or unit level.
You will be expected to apply a range of dismantling and reassembly methods and techniques. You will also demonstrate knowledge of installing and upgrading software packages and perform data back-ups. Computer security is paramount and an understanding of antivirus software, and any other measure that are in place to ensure the computer systems are secure and robust, needs to be demonstrated. This will include electrical, electronic and mechanical units and components, media storage drives, removable storage mediums, magnetic tape, computer infra-structure systems and internet / intranet network security.
Your responsibilities will require you to comply with organisational policy and procedures for the servicing activities undertaken, and to report any problems with the activities that you cannot personally resolve, or that are outside your permitted authority, to the relevant people. You must ensure that all tools, equipment and materials used in the servicing activities are removed from the work area on completion of the activities, and that all necessary job/task documentation is completed accurately and legibly. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions, and for the quality and accuracy of the work that you carry out.
Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to applying the correct servicing procedures. You will understand the dismantling and reassembly methods and procedures used, and their application. You will know about the computer equipment being worked on, and component properties, functions and associated defects, in adequate depth to provide a sound basis for carrying out the servicing activities, correcting faults and ensuring that the serviced equipment functions to the required specification and remains compliant with all standards and regulations.
You will understand the safety precautions required when carrying out the servicing activities, especially those for isolating the equipment. You will also understand your responsibilities for safety, and the importance of taking the necessary safeguards to protect yourself and others in the workplace.
