Summary for Patent: 5,697,896
Title: | Electrotransport delivery device |
Abstract: | An electrotransport delivery device (410) includes control circuitry for discontinuously delivering a beneficial agent (eg, a drug) through a body surface (eg, skin 400). For example, the device may be the type which is manually activated by the patient or other medical personnel to activate electrotransport drug delivery. Once electrotransport delivery has been activated, a timer (221) counts a transition interval, typically about one minute, during which the device is allowed to operate and the impedance of the body surface (400) is allowed to stabilize. Thereafter, the electrotransport current and voltage are then monitored and compared to predetermined limits. Allowing for the transition interval permits tighter tolerances in monitoring the applied current. |
