Indicator for electrophoretic transcutaneous drug delivery device

摘要: An indicator for indicating the in vivo delivery of a drug by electrophoretic deposition medicament through or on skin surface. The device includes layers forming reservoir containing drug, battery layer superimposed reservoir, and cover electrically conductive material fully enclosing having lip along its periphery to electro-conductively engage surface form an electrical circuit. indicator, such as LCD electrochemically phototropic (ECM) is circuit during which closing circuit, current causes activates ECM so indicate user.
