Abstract: The medicine reservoir contains medicine and a bag and may have flat or any other shape. A user programmable controller controls a pump on when and how much air or any kind of fluid is pumped into the bag. The bag then presses the same volume of medicine out of the reservoir into the user's body at approximately the same time. Pumping air requires little power so that the pump and the batteries have small weight and size. Hence, the apparatus is light, small, and flat to be attached to the user. The user feels like to use a large Band-Aid.
