Methods for implementing current delivery profiles used in an iontophoretic system

摘要

An iontophoretic system is provided, including a patch and a controller. The patch includes a plurality of electrodes electrically connectable to the controller and through which current is applied by the controller to the skin. The controller includes at least one current delivery profile, an input device, a control circuitry, and circuitry for generating the patch current. The current delivery profile is an element that can be changed independently of the other components of the controller. The control circuitry selects a current delivery profile using an input from the input device, and causes the current generating circuitry to generate and apply current to the patch electrodes in accordance with the read current delivery profile.
