Excuse me: I am a diabetic in your hospital. I used the usual insulin refill all the year round, and now the pen holder is broken. How should I solve it?

Generally speaking, hospitals have corresponding insulin pens that can be replaced. You can change these pens anywhere. Some places can be replaced for free, but some places need to be bought again. You can consult the endocrinology department of your local hospital. If it really doesn't work, you can change the insulin.
