HUMIDITY CONTROLLING ABSORBER FOR ELECTROTRANSPORT DRUG DELIVERY DEVICES

摘要

An improved package of an electotransport drug delivery device in a hermetically sealed foil pouch with controlled humidity. Inside the pouch the device and its electric circuitry are exposed to a high relative humidity environment that if uncontrolled leads to corrosion and subsequently malfunctioning of the device. The high relative humidity is necessary for keeping the water content of the drug reservoir in a specified range to maintain operability of the device. An electrotransport drug delivery device with a corrosion protectant such as a humidity-controlling absorber within the sealed pouch is disclosed.
