Experience shows quite clearly that only a well-balanced mix of in-house and private maintenance and repair services leads to results that are both technically and financially satisfactory in settings with limited resources. dr. Chris R. Mol, BME, NORTEC, 2015 Repairing

Troubleshooting faults in medical equipment Approach: • • • Have knowledge of principle of operation of equipment Know equipment history from the user and maintenance records Use service manuals, test equipment and correct tools Use correct trouble-shooting techniques (see further on) Perform root cause analysis Record equipment details in workshop receiving book. Note date, serial number etc. dr. Chris R. Mol, BME, NORTEC, 2015 Repairing

How to find User (Operator) & Service Manuals Lack of service manuals is #1 problem faced by BMETs in the field (#2 is acquiring parts) 1. 2. 3. 4. 5. Find it in your hospital Visit manufacturer’s website and manufacturers local representatives Visit Frank’s website at http: //www. frankshospitalworkshop. com/ Search the internet via general search tool (Google, etc. ) Use your BMET (Social) Network in Zambia & beyond Make sure you get all manuals with new & donated equipment Build your own digital library of docs/info & share via BMET website(s) dr.

Perform root cause analysis (many approaches possible) Events and causal factor analysis — evidence gathered quickly and methodically to establish a timeline for the activities leading up to the accident. Once the timeline has been established, the causal and contributing factors can be identified. Change analysis — This approach is applicable to situations where a system’s performance has shifted significantly. It explores changes made in people, equipment, information, etc. that may have contributed to the change in performance 5 Whys approach (Toyota) Example. Problem: The vehicle will not start. 1. Why? - The battery is dead. 2. Why? - The alternator is not functioning 3. Why? - The alternator belt has broken. 4. Why? - The alternator belt was well beyond its useful service life and not replaced. 5. Why? - The vehicle was not maintained according to the recommended service schedule. (fifth why, a root cause) Repairing

Perform root cause analysis: 5 Whys approach Example. Problem: The vehicle will not start. 1. Why? 2. Why? 3. Why? 4. Why? - The battery is dead. The alternator is not functioning The alternator belt has broken. The alternator belt was well beyond its useful service life and not replaced. 5. Why? - The vehicle was not maintained according to the recommended service schedule. (fifth why, a root cause) Not all problems have a single root cause. If one wishes to uncover multiple root causes, the method must be repeated asking a different sequence of questions each time. Repairing

Ordering spare parts • • • Identify and list faulty parts with part numbers Identify sources/suppliers of spare parts/component Collect quotations (pre-purchase procedure) Request for funds based on quotations Ensure that correct spare parts are procured Repairing

Using test equipment • Identify test equipment for specific equipment, such as: • ECG simulator • defibrillator tester • surgical machine tester • X-ray phantom tester • electric safety tester • Use test equipment correctly Repairing

Preparing and keeping records of works “Job Request Form” • • Record when the equipment comes to the workshop Record fault as reported by the user Record the time taken to repair/do the work Record the work done on equipment • Record spare parts used on equipment • Record consumables used on equipment • Record the maintenance staff who worked of equipment • Record the verifying officer on completion of work Preventive maintenance and calibration

Some items of equipment will be found to be damaged beyond repair. These will have reached the end of their lives, and must be taken out of service (decommissioned) and be replaced if the service they provide is to continue.
