Description

The present invention relates to the field of biomedical engineering, more specifically to electro-stimulating devices for the diagnosis and treatment of organs and tissues.

Known electrical stimulator of the gastrointestinal tract, comprising a housing formed by two stimulating electrodes isolated from each other and a dielectric sleeve, in which a stimulating pulse generator is installed, connected to the electrodes and to a power source for it [1. Pekarsky V.V. and others. Autonomic electrical stimulators of the gastrointestinal tract. - Tomsk: Publishing house of SSMU, 1995. - 132 p.].

The performance monitoring of this electric stimulator before use is carried out using the light-emitting diode included in the delivery.

The use of a light-emitting diode to check the operability of an electric stimulator before use requires observing the polarity of its terminals; when manipulating the terminals, it is possible to break the circuit of the generator of electro-stimulator with static electricity and contamination of the electric generator body is possible.

The present invention is the creation of an electrical stimulator that allows you to monitor its performance in a non-contact manner.

This task is achieved in that the gastrointestinal tract electrical stimulator, like the prototype, contains a light emitting diode and a housing formed by two stimulating electrodes isolated from each other and a dielectric sleeve, in which a stimulating pulse generator is installed, connected to the electrodes and to the power source for him.

According to the invention, a magnetically controlled contact and a light-emitting diode are sequentially connected to each other inside the housing, the magnetically controlled contact being able to connect under the action of an external magnetic field with one electrode, and the LED with another electrode, while the dielectric sleeve is made of optically transparent material.

The invention is illustrated by drawings, where

figure 1 shows a functional diagram of an electrical stimulator of the gastrointestinal;

figure 2 - magnetically controlled contact.

The stimulator of the gastrointestinal tract contains a housing in the form of a sealed capsule formed by a dielectric sleeve 1, two hemispherical metal electrodes 2, 3. Inside the housing there is a stimulating pulse generator 4 connected to a power source 5 and electrodes 2 and 3. Electrode 2 through a magnetically controlled contact 6 can be connected to the light emitting diode 7, the second electrode of which is connected to the electrode 3.

Magnetically controlled contact 6 can be made of ferromagnetic material (for example, permalloy). As a light-emitting diode 7, for example, the KIPD03A-1K-5 11-AAO.336.588 TU-85 indicator can be selected. The dielectric sleeve can be made of organic glass based on a linear thermoplastic polymer of methyl methacrylate, which has high permeability to visible and ultraviolet light, which is harmless to the body.

Before using the electric stimulator, its performance is checked. Magnetically controlled contacts 6 are closed using an external magnetic field created by a permanent magnet (can be supplied with the electric stimulator). Between the electrodes of the electrostimulator 2 and 3, a load appears (resistance of the light emitting diode, turned on in the forward direction). The stimulating pulse generator 4 starts to work on a given load. A pulse current of a stimulating pulse generator flows through a light-emitting diode 7, causing it to glow. Since the dielectric sleeve of the electric stimulator 1 is made of optically transparent material, the consumer visually perceives this glow. The presence of a pulsed glow of a light emitting diode indicates the efficiency of the electric stimulator. An electrostimulator enters the gastrointestinal tract with open magnetically controlled contacts 6, but a load due to the environment of the gastrointestinal tract appears between the electrodes of the electrostimulator 2 and 3. The stimulating pulse generator 4 begins to work, giving out to the electrodes 2 and 3 a series of stimulating pulses, which, acting on the smooth muscle of the intestine, cause it to contract in the form of a peristaltic wave, which moves the electrical stimulator to the distal digestive tract. The process of electric pulse exposure to the intestine is repeated until the electrical stimulator leaves the digestive tract naturally.

As a permanent magnet, you can use the Erga magnets based on Nd-Fe-B alloys or magnetoplastics on the same basis [http://www.erga.ru].
