Abstract
A portable infusion device assembly, having two side-by-side compartments, the first containing the drug or agent to be infused and an osmotic pump, and the second containing the driving liquid for the pump. The two chambers are separated during storage by a barrier. When the barrier is ruptured, the driving fluid is carried by means of a wick to the osmotic pump. The drug is then forced out of the device by the pressure developed by the osmotic pump. The assembly is characterized by a very flat profile, and is light, comfortable, and inconspicuous in use.
