This electrode is designed for contact electrotherapy and can be used in the treatment of inflammatory diseases of the paranasal sinuses, as well as for diseases of periodontal tissues.

The design of this electrode does not provide for simultaneous use with flexible fibrogastroduodenoscopy, which is practically not possible to use it in gastroenterology, in particular for the treatment of gastroduodenal ulcers. In addition, the electrode is not provided means to supply drugs directly to the contact element, which prevents its use for intracavitary contact treatment of gastroduodenal ulcers.

Contact element electrode has a rod shape with a rounded working end, provided with an insulating coating on the working surface and is made of-metal, formed by a spiral wire segments, arranged with mutual crossed that on the outside side of the element is assembled in a current-carrying wire. A feature of the electrode is that the contact element is designed with a blind axial cavity for drugs, equipped with a metal fitting placed in the coating and electrically connected with the output wire of the contact element, which is placed in the case of a porous dielectric material (see ed. mon. THE USSR 1797900, MKI 5 AND 61 N 1/04, 1/30. Electrode for electroplating and electrophoresis / Appl. 20.11.1999. , publ. 28.02.1993).

The electrode is intended for use in proctology, gynecology, and abdominal purulent surgery. The electrode is equipped with means for dosed supply of Lek is raised, his design does not provide for its simultaneous use with flexible fibrogastroduodenoscopy. The result excludes the possibility of using the analyzed electrode for conducting local contact electrophoresis of drugs in the treatment of gastroduodenal ulcers.

The technical problem solved by the invention relating to the device is the creation of an electrode design which allows it to be adapted to flexible fibrogastroduodenoscopy.

To solve the task with respect to the device in a known electrode for contact electrotherapy hollow bodies containing a contact element made of a porous elastic material with electric element inside associated with the current-carrying wire, and a flexible tube for the supply of a medicinal product that is connected with the contact element according to the invention the current-carrying wire placed in the channel of the flexible tube for the supply of drugs, while the proximal end of the flexible tube for the supply of a medicinal product is equipped with a connector with two inputs respectively for connecting the syringe and the output of the current-carrying wire.

According to the invention the tail part of the current-carrying wire placed inside a contact element made in the form of a loop.

According to the invention the tail part of the current-carrying wire placed inside a contact element made of serpentine.

According to the invention the contact element is made in the form of a hydrophilic sponge.

Adapted to flexible fibrogastroduodenoscopy active electrode makes it possible to carry out electrophoresis under visual control and can be used for intracavitary contact treatment of gastric ulcer and duodenal ulcer.

Connector with two inputs respectively for connecting the syringe and the output of the current-carrying wire provides easy plug connection of a syringe with a flexible tube for the supply of drugs, which is important in adapting the electrode to the instrumental channel fibrogastroduodenoscopy before medical procedures.

Placing a current-carrying wire in the channel of the flexible tube for the Nala of fibrogastroduodenoscopy, on the other hand, provides additional ionization of the electrolyte - drugs in the environment in which it was located.

The execution of the electrically conductive element placed inside of the contact element, in the form of a bent end portion of the current-carrying wire (in the form of a loop or serpentine) provides a supply of electric current to the contact element and the desired degree of ionization of the electrolyte while maintaining a soft elastic material structure of the contact element which is essential for the introduction of the electrode into the cavity of the body through the esophagus.

Performing a contact element in the form of a hydrophilic sponge due to its porous structure, softness and elasticity prevents injury of the mucous membrane, and also allows you to hold the required number of medications and provides a soft and a snug fit of the contact element of the ulcer over the entire area, which in turn eliminates the occurrence of nonuniformity of the electric field and the appearance of the resulting negative effect of burns of the mucous membrane of hollow organs.
