OSMOTIC SYSTEM FOR DELIVERY OF DILUTE SOLUTIONS

摘要

OSMOTIC SYSTEM FOR DELIVERY OF DILUTE SOLUTIONS There is disclosed a device that is capable of providing a constant rate of delivery of beneficial agent at concentrations less than saturation. Osmotic bodies or diffusional bodies containing the agent are contained within a reservoir of the device. A saturated solution of the agent is delivered at a constant rate from the bodies, and this solution is diluted at a constant rate by water diffusing into the device. The rate of agent delivery, the concentration of the agent solution delivered, the total dose of agent delivered, and the number of agents delivered from the same device may all be independently controlled.
