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.

A device for the transdermal administration of a drug to a patient, said device comprising a reservoir for the drug to be administered, said drug being associated in the reservoir with a pharmaceutically compatible ointment, cream or jelly-like carrier, said reservoir being largely impermeable to the drug and having a defined passage means through which the drug is supplied to the skin, said defined passage means comprising a drug permeable wall member, providing a face of the reservoir, said drug permeable wall member having a first surface forming part of the reservoir and a second, opposite, surface of a defined area for contacting the skin whereby the device positively conveys the drug in the direction of the skin at a predetermined rate, means for removably attaching the reservoir to a support member, said support member being engageable with a face of the reservoir remote from that face formed by said wall member, wherein the face of the reservoir remote from that face formed by said wall member comprises a plate movable in piston-like fashion towards said wall member, the device further including a spring acting against said movable plate to cause a constant egress of ointment, cream or jelly-like carrier from the reservoir to the skin through said wall member, said support member in use substantially surrounding and being readily detachable from that portion of the patient\s body to which the device is applied.
