StampPump is a postage-stamp-sized (27x27x6 mm), fully-self-contained, closed-loop insulin patch pump system that is filled at the factory with enough insulin to treat a person with T1- or trauma-induced hyperglycemia for a full week. The device is shelf stable for at least 90 days and so is compatible with critical-care or forward deployment use. We propose to augment this system with the ability to control delivery of counter-regulatory medications -- either glucagon or dextrose -- so that it can automatically mitigate hyperglycemia while reducing the risk of hypoglycemia. The augmented system would be designed for simple deployment by critical care nurses or even field medics
