When we use a medical device such as a blood glucose monitor or an insulin pump, it is necessary to keep such devices charged, but one should be more careful when using USB chargers as they can overheat the device and in serious cases. May cause burns, injury and fire.
Whenever purchasing a medical device, read, understand, and follow the device manufacturer’s instructions. Also, use only the charging accessories that come with the device.
The US Food and Drug Administration (FDA) has issued guidelines regarding safe charging which are as follows:
1) Use only the cables, chargers and adapters that come with the device as they provide the correct amount of power to charge it. Chargers that are specific to phones or tablets can deliver too much power, creating a greater risk of overheating, sparks or fire.
2) When purchasing your medical device and charging accessories, always inspect them properly for any broken or damaged parts. If you find any damage, contact the company for an exchange.
3) Charge your device when you are awake and not leave it charging before going to bed. And keep it where you can easily see it while charging. Do not place it on a soft surface such as a bed, sofa or cloth while charging. At such a level the device overheats.
4) When your device is fully charged, remove the charger as soon as possible.
5) Protect your device from extreme temperature environment eg do not place it in very cold or hot environment.
