ABSTRACT:
A device for transdermal administration of a drug comprises a reservoir containing the drug and a supporting strap, or band, which substantially surrounds a limb of the patient and holds the reservoir in position on a limb of the patient. The reservoir is generally non permeable to the drug, but has a membrane, or plate, of defined surface area through which said drug can pass. In use, this membrane or plate is held against the patient's skin to allow the drug to be absorbed. The device further includes cooperating locking mechanisms for detachably securing the reservoir on the strap or band whereby the supply of drug can be replenished by removing the spent reservoir and inserting a fresh one containing a new supply of the drug.
