(54) GASTROINTESTINAL ELECTROSTIMULATOR

The invention relates to medicine, and specifically to stimulators of the gastrointestinal tract.

Electrostatic stimulators of the gastrointestinal tract, known as a stationary device, are known, including a pulse generator, a power source, and a electrode 1.

A disadvantage of the devices is the relatively high patient trauma caused by the need to remove the electrodes through the throat.

The purpose of the invention is to reduce trauma.

Achieving the goal in an electrostimulator of the gastrointestinal tract containing a pulse generator, a power supply j and an electrode, electrodes are two electrically isolated parts of a drug capsule, and a pulse generator and a power supply are placed inside the capsule. .

FIG. 1 shows the electrostimulator torus structure; in fig. 2 - structural scheme.

An electrostimulator consists of a body 1, a capsule, which is made in the form of two electrically isolated parts that serve as electrodes 2 and 3, which are in contact with the intestinal wall. Inside the housing 1 is placed a generator 4. pulses and power sources 5 and 6 in the form of two electroplating. items. Structurally, a 4-pulse generator is glued to the connecting flange 7 (material: aluminum alloy D16A, covered with an AjOj oxide film). Both parts of housing 1 (electrodes 2 and 3) are interconnected by means of a connecting flange 7 as follows: electrode 2 of housing 1 seals the generator 4 pulses with an adhesive layer 8 between electrode 2 and connecting flange 7, electrode 3 of housing 1 is connected to a connecting flange 7 with a thread 9 and seals the above 2Q under the power sources 5 and 6 of the rubber gasket 10. The power sources 5 and 6 are isolated from the walls of the electrode 3 of the housing 1 with a dielectric sleeve 11. The electrodes 2 and 3 of the housing 1 are insulated from each other

using a connecting flange 7, a rubber gasket 10 and a dielectric coating 12.

The size of the electrostimulator of the gastrointestinal tract is limited by the possibility of introducing it into the patient's gastrointestinal tract by swallowing.

The electrostimulator of the gastrointestinal tract works in a following way.

The electrostimulator is inserted into the patient's gastrointestinal tract by swallowing. A series of rectangular pulses of a given characteristic comes from a generator of 4 pulses to the electrodes 2 and 3 of an electrostimulator, which are in contact with the intestinal wall. Electric impulses, acting on the intestinal wall, cause the appearance of a response in the form of a peristaltic implantation wave, which advances the electrostimulator and the contents of the intestine to its distal sections, to which the next series of impulses is applied and the process repeats.

Thus, it is possible to avoid the unpleasant and transmatum moments of the zoidal method of stimulating the gastrointestinal tract.
