Description

The utility model relates to the field of medicine and medical technology, in particular to devices for reflexology, and can be used to treat diseases with the help of electropuncture.

An analogue of a useful model with spaced electrodes — active and indifferent — is the Karat acupuncture point electrostimulator, which acts on the points with direct current and pulse signals with various envelope shapes and high-frequency filling of a rectangular pulse (Portnov F.G. Electropuncture reflexotherapy. - 3rd ed ., revised. And additional - Riga: Zinatne, 1988. - p. 352). The device is designed to search for acupuncture points on the human body and the therapeutic effect on them through cutaneous electrodes, as well as acupuncture needles, used in reflexology, anesthesiology, internal medicine clinic, neuropathology, sports medicine, scientific research. It is used in stationary and field conditions. However, this device has a mass of 1.5 kg, it runs on AC power and battery, which makes it difficult to use at home. Also, during the operation of the device, the constant presence of a medical worker is necessary due to the possibility of electrical injuries.

The prototype of the utility model is the transdermal electron neurostimulator "Electronics CHENS-03", working with zonal electrodes (Passport for the transdermal electron neurostimulator "Electronics CHENS-03", reg. Ud. Ministry of Health of Russia No. 83/1010-27. Certificate of Gosstandart of Russia No. POCC.RU. AU) 40. В 00026. 195251 St. Petersburg, Bioimitator, tel./fax: (812) 559-98-29; Shteregerts A.E., Belaya N.A. Massage for adults and children. - K .: Health, 1994. - p. 384). The device consists of a plastic case on which a control LED is located, a window for controlling the intensity of exposure (in arbitrary units from 0 to 9), a removable block of working electrodes having a contact surface in the form of an oval with a diameter of 16 mm and a length of 32 mm, with 7 inside electrodes, and on the circumference of 16 electrodes 1.8 mm thick with a spherical contact surface, a power switch of the impact regulator, a compartment for the power battery. The disadvantages of the prototype: the device CHENS-03 has a full-time group of zone removable electrodes located on the body and designed for percutaneous electroneurostimulation of reflexogenic zones. Zone processing is carried out when none of the elements is installed in the projection of acupuncture points (AT). Stimulation of AT is possible if one of the 7 active electrodes gets on its skin projection. The area of the multielectrode, however, does not allow working on the hands, feet, head and ears, which limits the effect of the device on the skin projection of AT. When using a multielectrode, an electric current flows along the created electric circuit, depending on the location of the surrounding indifferent electrodes. The depth of current flow is unknown, because electric current passes along the path of least electrical resistance, and these are deep intercellular spaces. The depth of AT is different in different parts of the body surface, so the probability of direct stimulation of AT is extremely small, plus tissues outside the AT substrate that are part of the electrical circuit are stimulated, i.e. a parasitic effect occurs, which reduces the specificity of the reflex response.

The objective of the utility model is to create a device for electropuncture, providing electrical safety and ease of use both independently at home, and in combination therapy with other treatment methods in a hospital.

EFFECT: access to skin projections of acupuncture points on hands, feet, head, auricles, complete autonomy with respect to external power sources, electrical safety.

The proposed device for electropuncture contains a housing that consists of two covers - the top 1 and bottom 2. On the top cover there is a button 3 protruding outward. Inside the cavity, between the covers, in a special metal case 6 there is a piezoelectric element 7 with a current collector 8. Two pistons 9 and 10 are attached to the piezoelectric element from the key. The piezoelectric element is an annular cylinder with plates 11, cylindrical a form for picking up pulses of electrical voltage generated by a piezoelectric element under the action of a mechanical load 12. An active electrode 13 is connected to the plates, made in the form of a conductor with a working tip 14, which looks like a plug with a metal pointed end and is designed to act on the acupuncture points of the body. The electrode 15 with a tip in the form of a metal plate is "passive". Overall dimensions 245 * 55 * 25 mm, weight 0.13 kg. Service life 5 years (provided that no more than 9000 operations per year).

The utility model is illustrated by the following figures: Figure 1 shows the proposed device, a General view. Figure 2 is the same appearance. Figure 3 is the same, in section. Figure 4 - chain electrical circuit of the device under the action of a mechanical load.

A device for electropuncture works as follows. Points for electropuncture are marked on the patient's body. The device for electropuncture is brought up to the intended point at a distance of 5-10 mm and the key is pressed and released from 5-6 times. The characteristic cracking and sparking in front of the metal nozzle (“active electrode”) indicates the operation of the device. When a key is pressed, the piezoelectric element is triggered. Pulses generated by a piezoelectric element with a voltage from several units to several tens of volts and a current of several tens of microamps are removed by means of plates and fed to electrodes consisting of a conductor and a working tip. The tip of the "passive" electrode is pre-fixed to the body using a patch or held by hand. The tip of the "active" electrode is brought into contact with the skin at an acupuncture point. For example, with peripheral neuropathy of the facial nerve, taking into account the anatomical and physiological characteristics of the muscles, the following points are affected on the affected side:

1) forehead: smooth frontal muscle and nose pyramidal muscle - ST8, BL3.4; GB14, GV24, EX-HN3 (yin-tan);

2) the area of the orbit: the large circular muscle of the eye (muscle of the proud) -ST1.2; BL2, GB1, TE23, EX-HN5 (tou-guan-min) - (on the upper side of the eyebrow, above the pupil of the straight-looking eye, EX-HN6 (yu-yao), EX-HN3 (yin-tan), EX-HN9 ( tai yang);

3) cheekbone: big muscle of laughter - ST7, SI18, GB2.3;

4) cheek: flat muscle - ST6.7; SI18;

5) nose: a muscle that lowers the nasal septum, helping to wrinkle the nose, - EI20, GV25;

6) the mouth and chin: a large circular muscle for closing the mouth, square muscle of the lower lip, canine-shaped short muscle, triangular muscle of the lower lip, chin short muscle - ST3.4; CV24, GV26, EX-HN19 (d-he) - in the middle of the most prominent part of the chin.

The time of one session is 5-7 minutes, 2-3 sessions daily, the course of treatment is 10-15 days. Thus, the advantages of the proposed device are light weight and dimensions, complete autonomy in relation to external power sources, ease of use. The device can be used both independently at home, and in combination therapy with other treatment methods in a hospital.
