Can insulin pump pass the security check of high-speed rail?

**Can***, insulin pump can go through the security check of high-speed rail, because it belongs to general medical equipment items, not flammable and explosive goods and controlled dangerous goods, and not drugs and restricted articles. However, it should be reminded that when going through the security check, you need to put the insulin pump in your carry-on baggage and present a medical certificate to prove that it is a necessary medical device. Also, when traveling by air, insulin needs to be carried in your carry-on and cannot be checked in.
