Checking the Beijing Elderly Hospital website, I learned that insulin pumps are electronic products with electronic boards and metal inside, which will cause an alarm when passing through the security gate. For diabetic patients, they can carry sufficient amounts of insulin preparations, as well as hypodermic syringes with needles, but they need to show a medical certificate. When going through security, the right to request a direct visual inspection of insulin and diabetic supplies (without going through equipment such as X-rays) is more conducive to keeping the insulin stable.
