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.

Claims

1. A container for a dosage of a biologically active agent in fluid form adapted to be received within the housing of a pump for delivery into the body of a patient comprising a closed, collapseible bag impermeable to the material comprising said dosage, said bag having a basal surface and a self-sealing welt extending circumferentially around said bag in a plane substantially parallel to and spaced apart from said basal surface.

2. The container of claim 1 further comprising a circumferential flange integral with and extending radially outwardly from said basal surface.

3. The container of claim 1 or 2 further comprising a quantity of liquid filling said bag.
