It comes with a transfer guard the blue piece at the top that is removed before inserting the reservoir into the pump. This assists with pulling the insulin from a vial into the reservoir.

As a general rule, most bottles of insulin are good for 28 days once they're opened. Of course, how quickly a person goes through a vial is highly individual. Some may go through a bottle in a week or two. Others, on a lower dosage, may not use all the insulin within four weeks. But the drug's stability and potency is only guaranteed for 28 days. Opened insulin pens typically last 14 days, though some last only 10 days. If you're uncertain, check with your mother's pharmacist to find out how long her insulin should last.
