The Civil Aviation Authority are asking that all passengers who have medical devices such as Insulin Pumps and Continuous Glucose Monitoring systems carry a card to remind themselves and the security officer about what precautions both sides must take to travel safely and securely.
For passengers the card can be printed by clicking on the link below or simply googling Medical Devices awareness card.
You should also have a letter from your GP or hospital doctor saying that you are wearing the device.
These devices should not be put through X ray scanners whether on your body or not. You shouldn’t be required to remove them from your body either. You may need to check what security alternatives exist in foreign airports but the UK has other ways of determining your safety to fly.
