Patient Monitor Power Issue: Diagnosis and Proper Handling Under Warranty (Real Case)

 




A Real Situation from Field Work


Today during a hospital visit, I came across an issue with an Allied multipara patient monitor. The device was not functioning properly, and the initial observation suggested a power-related problem.


---


Initial Observation


The monitor showed signs of power failure:


- The device was not turning ON properly

- No stable power indication

- Intermittent response during switching


👉 These symptoms clearly pointed towards a possible power supply issue.


---


Diagnosis Process


Instead of directly opening the device, a basic diagnosis was performed:


1. External Power Check


- Power cable and socket were checked

- Input supply was verified


2. Basic Functional Check


- Power button response observed

- Display behavior monitored


👉 Conclusion: Internal power supply issue suspected


---


Important Decision: Not Opening the Device


At this stage, one important factor was considered:


👉 The device was under warranty


So instead of opening or attempting internal repair:


- The device was left intact

- No internal tampering was done


---


Proper Action Taken


- The issue was reported to the OEM (Original Equipment Manufacturer)

- Necessary details were shared

- Further action was handed over to authorized service support


---


Why This Decision Matters


1. Warranty Protection


Opening the device could void the warranty.


2. Professional Ethics


Following proper protocol is a sign of a responsible biomedical engineer.


3. Safe Handling


Avoids unnecessary risk and ensures proper service from authorized experts.


---


Key Learning from This Case


- Always check warranty status before repair

- Diagnosis is important, but action should be smart

- Not every issue should be fixed manually


👉 Sometimes, the best decision is to step back and follow the correct process.


---


Conclusion


This case highlights an important aspect of biomedical fieldwork — not just technical skills, but also decision-making and professional responsibility. Knowing when not to repair is just as important as knowing how to repair.


---


Personal Note


This experience taught me that being a biomedical engineer is not only about fixing machines but also about making the right decisions at the right time.
