Iontophoretic delivery device and power supply therefor |
摘要 |
An iontophoretic drug-delivery device incorporating a power supply which minimizes the cost of the batteries needed by operating the batteries in a series configuration at the start of delivery, when the patient's skin resistance is high, and by switching the batteries into a parallel configuration when skin resistance drops. An automatic switching circuit for achieving this transition is included.
