ELECTRODE FOR IONTOPHOREIS WITH SOLUTION LEAKAGE-PREVENTING SYSTEM

PURPOSE: To prevent the leakage of a solution from the bioelectrode and the like of an iontophoresis by providing the electrode with a solution absorbing device arranged in a pocket device for absorbing a contacted vessel, and a handle device for releasing the solution absorbing device into the vessel. CONSTITUTION: The interior of a pocket 42 and the interior 46 of a bioelectrode are separated by a partition 48. A rope or a string 52 for destruction is elongated through the upper opening of the pocket 42 and the partition 48, and they are combined with a solid button 56. A elastic sponge 60, which is certainly compressed but still elastic one such as a compressed cellulose sponge, is arranged in the pocket 42 of the upper of the partition 48. The size of the pocket 42 and the position of the partition 48 are maintained in the state of compressing the sponge 60 until the partition 48 is destroyed by pushing the button 56 toward the partition 48 by stretching the rope 52, i.e., a string for destruction. In the state of the partition 48 being destroyed, the compressed sponge 60 is released and inflated at the outside of the pocket and reaches the interior portion 46 of a hollowed cavity, and then the contacted solution is absorbed by the inflated sponge 60.
