This is a reasonably accurate model of Medtronic's insulin pump: https://www.medtronicdiabetes.com/products/minimed-780g-insulin-pump-system

If you're considering getting a tubed insulin pump, try taping this to your stomach with 60cm string (or asking your doctor for a test cannula) to see whether you can deal with the attachment. It helped give me confidence in my decision to buy the pump (which is otherwise very expensive).
