    摘要： An improved electrode and iontophoretic device and method where the electrode exhibits varied resistance. The electrode is made of a conductive material and applied to a flexible substrate. The variation in resistance can be achieved by varying the thickness of the electrode across its length or by varying the conductivity of the material across the area of the electrode or a combination of both. A pair of such electrodes may be used with a power source in electrical relation thereto and applied over a layer of agent to the skin to deliver the agent into the skin iontophoretically. The pair of electrodes may be shaped so as to cover a portion of the face, hands, feet or other body parts to iontophoretically apply particular agents to those areas.

    摘要： The present invention relates to a drug delivery device for mixing and delivering a drug by injection. The device includes a housing having a first port or opening therein that receives a first container that contains a fluid or powdered drug, for example a lyophilized drug. The housing can also include a second port or opening that receives a second container that contains a fluid to be mixed with the drug to form an injectable fluid. The device includes a manifold having a channel that fluidly connects the first and second containers. A penetrating membrane such as a needle is used to inject the drug into a patient which is in fluid communication with the first container. The needle is movable from a storage position in the housing to an injection position extending through the housing.
