Medical Device Safety

Medical devices are essential tools for diagnosing, curing, or treating conditions, and their safe operation requires proper knowledge and preparation.

Overview

A medical device is any product used to diagnose, cure, or treat a condition, or to prevent disease. They range from small and simple, like a blood glucose meter, to large and complicated, like a ventilator. You might use one at home or at work, or you may need one in a hospital.

Guidelines for Safe Use

To use medical devices safely:

  • Know how your device works and keep instructions close by.
  • Understand and properly respond to device alarms.
  • Have a back-up plan and supplies in the event of an emergency.
  • Keep emergency numbers available and update them as needed.
  • Educate your family and caregivers about your device.

Frequently Asked Questions

Schedule a formal training session with your healthcare provider or a certified medical equipment specialist where caregivers practice operating the device, including troubleshooting common errors and performing emergency shutdowns. Provide them with written, step-by-step instructions and a list of emergency contacts. Regularly test their knowledge by asking them to demonstrate key tasks, such as changing filters or responding to a power outage, to ensure they are confident and prepared to act without hesitation.
Do not ignore the alarm or simply turn it off without understanding the cause. First, check the patient’s condition to ensure they are stable. Then, immediately consult the device’s user manual or the quick-reference guide provided by your healthcare provider to identify the specific error code. If you cannot resolve the issue within the timeframe recommended by your care team, or if the patient shows signs of distress, call your provider’s emergency line or 911. Keeping a log of alarms and their resolutions can help your clinician identify recurring issues.
Wash your hands thoroughly with soap and water before and after handling the device. Clean the exterior surfaces with a mild, non-abrasive disinfectant wipe as recommended by the manufacturer, avoiding any openings or electrical components. Replace consumable parts, such as filters, tubing, or batteries, on the schedule specified by your provider, even if they appear clean. Store the device in a clean, dry area away from dust and pet hair, and inspect all connections for signs of wear or contamination during routine checks.
Identify whether your device has a built-in battery backup and know its maximum runtime. If the battery life is insufficient for a potential outage, have a portable generator or a backup power supply ready and tested regularly. Keep a list of emergency contacts, including your equipment supplier and local utility company, in a visible location. Develop a plan for where to go if the power is out for an extended period, such as a hospital or a relative’s home with reliable power, and ensure you have enough supplies to last until you can reach that location.
