Abstract
A self-contained body mounted pump assembly for continuously administering a therapeutic agent parenterally. The pump has a transparent top through which the contents can be seen and outwardly flaring sides to provide for comfort, stability and other useful features. The pump assembly is driven by a fluid imbibing, preferably osmotic pump and contains its own source of actuating fluid. Means for superimposing a pulse dose on the tonic flow are also described.
