Abstract
A method for manufacturing a transdermal drug delivery device (10) is disclosed wherein a component (32) and/or a subassembly (20) are intentionally adapted to be separable from the rest of the device for disposal which is more medically or environmentally acceptable. In one embodiment, device 10 comprises upper and lower housings (16, 20), with lower housing (20) being separable from upper housing (16) and foldable upon itself to minimize medically unacceptable contact with, e.g., a drug reservoir (26 or 28) contained therein. A device (10) made in accordance with the invention is included.
Claims19
A method of discarding drug-containing portions of a transdermal electrotransport drug delivery device, the device including an electrical power source, a pair of electrodes electrically connected to the power source and a drug reservoir in electrical contact with one of said electrodes, the drug reservoir being positioned in a housing which is separable from the device, the housing having an adhesive surface, the housing being foldable upon said adhesive surface when the housing is separated from the device, comprising:
- separating the housing containing the drug reservoir from the device;
- and
- folding the separated housing upon itself to adhesively seal the drug reservoir within the folded housing.
