Description

The invention relates to medical equipment and can be used to activate biologically active (reflex) points using electric current for the treatment and prevention of a number of diseases.

A device for electrical stimulation [1] is known, which contains an acting element made in the form of a piezoelectric ceramic plate with an axial hole, wherein an electrode is located on the working end of the plate and equipped with a ball of electrically conductive material located in the axial hole of the piezoelectric ceramic and a second electrode located on the non-working end while the plates are connected electrically to the ball.

The disadvantage of this product is the complexity of the design, leading to a decrease in reliability during operation.

At the same time, a ferroceramic device is known for influencing biologically active points [2]. The specified device consists of an active element made of a round plate of a ferroelectric with a double-sided metallized coating, and the electrode is made in the form of an arc located outside the active element at a distance equal to the radius of the active element, and is connected by soldering to a conductive surface.

The disadvantage is the fragility of the structure, leading to a quick failure of the product, as well as the open components of the cylindrical piezoelectric element, which during operation of the product are covered with sweat and close the base and top of the element, which, in turn, leads to a short circuit and a decrease in reliability.

It is also known a device for influencing acupuncture points, taken as a prototype [3], consisting of an active element made in the form of a round plate of a piezoelectric element with a double-sided metallized coating placed on the inner surface of the electrode body and connected to one side by soldering with a conductive surface made in the form of a cup-shaped body-electrode, and the space between the piezoelectric element plate and the cup-shaped body is filled with insulating material.

The disadvantage of this product is the design implemented using manual assembly and not allowing the use of automated assembly technology.

The technical result of the invention is to simplify the design for assembly.

This result is achieved by the fact that a washer is inserted into the space between the active element and the sides of the cup-shaped body made of solid insulating material, for example fluoroplastic, having an inner hole of two different diameters, the side of the washer having a smaller inner diameter facing the electrode body and fastened with it and the washer with conductive glue.

In FIG. 1 schematically shows the design of the proposed device:

a) bottom view

b) a side view and

c) an enlarged part of the structure.

In FIG. 2 shows the application of the device: a) location relative to the reflex point; b) fixing the device.

In the figures indicated:

1 - bowl-shaped body-electrode,

2 - a washer made of solid insulating material having an inner hole of two different diameters,

3 - conductive glue,

4 - an active element made in the form of a tablet of ferroceramic material,

5 - surface of the patient’s skin,

6 - reflex point.

7 - fixing material, for example adhesive tape.

The assembly of the device consists in the following operations:

- a washer 2 is inserted into the bowl-shaped body 1;

- conductive adhesive 3 drips into the bottom of the washer;

- an active tablet element is inserted into the hole of the washer.

After the glue hardens, the structure becomes hard.

The device operates as follows.

A device is mounted on the selected reflex point 6 (Fig. 2a) on the patient’s skin surface 5 in the reflexogenic zone so that the surface of the piezoelectric element 4 and the edge of the housing 1 are in contact with the skin surface above the reflex point — the receptor.

Then (Fig. 2b) the housing of the device 1 is fixed on the body with any material 7, for example, with an adhesive plaster.

When the patient moves under the device, there is a movement of skin areas under the action of contraction - muscle relaxation, which causes a micro displacement of the device and, accordingly, its electrodes 4 and 1 relative to the receptor. As a result of this displacement, a mechanical dynamic effect is exerted on the ferroelectric tablet 4, which leads to the manifestation of the piezoelectric effect, as a result of which an electric potential of a different sign appears on the upper and lower sides of the tablet. For example, if the positive potential “+” appears on the free surface of the piezoelectric element, then the negative “-” appears on the other, glued to the bowl-shaped body, and vice versa.

The electric potential from these surfaces forms an electric field on the skin surface, which causes an electric current acting on the reflex point, thereby achieving a beneficial effect on the reflex points in the treatment and prevention of a number of diseases.
