Insulin pumps (and their cannula; not a "needle") are installed 24/7. They can be "suspended" and the insulin delivery hose unhooked, but they are generally there, and active, at all times. Likewise, a CGM (continuous glucose monitor) will provide, as the name says, continuous monitoring. Both use adhesives to keep them attached and generally remain so, even while sleeping.
Hypoglycemia also may not lead to "waking". After all, a diabetic coma may result from low blood glucose, depending on how quickly it crashes.
