Abstract
A delivery device for delivering a liquid containing a drug includes a first diaphragm within a housing defining a first contractible-chamber on one side of the diaphragm for holding a supply of the liquid to be delivered, and a second contractible chamber on the opposite side of the diaphragm including an electrolytic cell capable of generating a gas according to the electrical current passed through the cell electrolyte. The device further includes a second diaphragm, a control valve, and a spring, for compensating the rate of delivery of the liquid for variations in ambient pressure and temperature.
