초록 ▼

A multiple site drug iontophoresis electronic device configured for controlling infusion of ionic drugs into a patient through a plurality of electrode pairs. The device includes a plurality of electrode driver channels wherein each driver channel includes an electrode output configured for electrical connection to at least one of the plurality of electrode pairs through lead wires. Each driver channel is electrically isolated from the other driver channels and includes an independent current sink which controls current intensity through the electrode output. A common controller operates the driver channels as a function of treatment parameters supplied by the patient.

대표청구항 ▼

An electronic, iontophoresis controller for controlling infusion of ionic drugs into a patient, the controller comprising: a plurality of iontophoresis source and return electrodes configured for attachment to the patient\s skin, wherein each source electrode contains the ionic drugs and creates an electrical current path through the patient with at least one corresponding return electrode for transcutaneously delivering the ionic drugs into the patient; controller means for controlling operation of the iontophoresis source and return electrodes; and a plurality of iontophoresis electrode driver channels wherein each channel includes: an iontophoresis electrode output configured for electrical connection to at least one source electrode and at least one corresponding return electrode; an independent direct-current regulator which generates a direct-current output at a selected direct-current intensity through the electrode output; and isolation means coupled to the electrode output and the independent current regulator for electrically isolating each electrode output from the electrode outputs of the other driver channels and for electrically isolating the controller means from the electrode outputs of at least one driver channel,
