Abstract
An iontophoretic bioelectrode includes an enclosure having a bottom wall formed of a membrane through which ions may migrate when subjected to an electric field, and an upper wall joined to the bottom wall to define an interior compartment for holding an ion-containing solution. An electrode in the form of the male portion of a conventional clothing snap is mounted to the enclosure to communicate electrically with solution contained in the interior compartment. A needle receiving element is mounted in the upper wall of the enclosure. This element is in the form of a section of conduit having a receiving end, which is directed upwardly, and a blocking end which includes a platform for preventing a needle inserted into the receiving end from passing all the way through the conduit. A resilient plug is disposed in the receiving end of the conduit to prevent solution from escaping from the interior compartment. The plug is formed of a material through which a needle may be inserted but which, when the needle is retracted, closes about the opening made by the needle to prevent the escape of solution.
