MULTIPLE PART ELECTROTRANSPORT DRUG DELIVERY DEVICE

摘要

An electrotransport device (200) for delivering a therapeutic agent through a body surface of a patient. The device has an electronic module (204) that can be coupled with a reservoir module (202) to form the electrotransport device. The reservoir module has a reservoir that contains the therapeutic agent for delivery through the body surface by electrotransport. The reservoir module also has a cutout (268) forming a channel (267) having a narrow channel portion and a less narrow channel portion with channel walls. The electronic module has.circuitry for electrically driving the therapeutic agent for electrotransport and having a body with a narrow portion and a less narrow portion corresponding to the narrow channel portion and the less narrow channel portion. The narrow portion of the electronic module can be guided into the.narrow channel portion through the less narrow channel portion of the reservoir module.
