Description

The invention relates to medicine, specifically to a device for reducing the negative impact of a liquid crystal computer monitor on a person.

A device is known for protecting biological objects from radiation from cathode ray tubes (Pat. RF No. 2139579, class G12B 17/00, G21F 7/00. Device for protection against radiation. Variants).

In the first embodiment, the device comprises a square conductive frame with wires located between its sides, galvanically connected both to the frame itself and to each other. In the second embodiment, the frame is made in the form of a rectangle. Both versions of the device form "mesh metal bags" worn on the back rounded parts of the cathode ray tubes. Frames and wires are made of copper, silver and other conductive materials.

The disadvantage of such devices is that they do not protect computer users from harmful radiation from the cathode ray tube, because they not only do not attenuate direct radiation, but also reflect the opposite.

A device for protecting a person from radiation from liquid crystal monitors is known according to the same principle (Pat. RF No. 2187846, class G12B 17/02. Device for protection against radiation) and having the same disadvantages as the above-mentioned device variants.

It is known that periodic and non-periodic compression and relaxation of muscles is accompanied by the appearance of ultra-low-frequency flicker-noise (FS) emfs in them, under the influence of which PS currents flow in the muscles, normalizing biochemical processes, both in the muscles themselves and in organs connected by information channels with working muscles (Activated fluids, electromagnetic fields and flicker noise. Their use in medicine and agriculture: monograph / OA Pasko, AV Semenov, GV Smirnov, DG Smirnov. - Tomsk: Tomsk State University of Systems Compositions and Radioelectronics, 2007. - 410 p.).

Experimental data on the occurrence of FS EMF during compression and muscle relaxation were first shown in the description of the patent of the Russian Federation No. 2201269, class. A61N 1/36. A device for stimulating the oral cavity.

A device for magnetotherapy is known (Pat. RF No. 2496533, class A61N 2/04. Device for magnetotherapy). The device comprises a flicker noise current generator and a flat rectangular coil made of a ribbon cable, for example, FRC-64. A rectangular coil is located between two identical rectangular pieces of dense fabric and is fixed between them. The flicker noise current generator is located in the outer pocket, sewn to the outer surface of the upper section of dense fabric in its lower part. The device can be used in the form of bedspreads for beds and couches. A person is located on the longitudinal axis of a flat coil. Muscle compression and relaxation are not required. It can be used to protect pregnant women from anthropogenic magnetic fields.

The properties of such a device for magnetotherapy are used in the proposed device to reduce the negative impact of a liquid crystal computer monitor on a person. A positive effect is considered a therapeutic effect.

Modern medicine cannot fully answer the question of why working on a computer negatively affects the human body. When working on a computer, visual acuity ("computer visual syndrome") decreases, various types of osteochondrosis appear, and the likelihood of hemorrhoids increases. In pregnant women, blood supply to the abdominal cavity, including in the uterus, worsens, and the number of miscarriages increases. Doctors suggest normalizing the time spent working at the computer, namely, to take a fifteen-minute break every hour, during which to perform special exercises, including for the eyes.

The objective of this study is to reduce the number of diseases of a person working at a computer containing a liquid crystal monitor using a device to reduce the negative impact of a liquid crystal computer monitor on a person

The solution to this problem is achieved by the fact that the device for reducing the negative impact of a liquid crystal computer monitor on a person contains a rectangular frame made of a dielectric cable channel of rectangular cross-section, worn on the end parts of the monitor, an inductive coil is located inside the frame, a socket part is fixed in one of the lower corners of the frame coaxial connector, with the ends of which the ends of the inductive coil are galvanically connected, a flicker-noise current generator whose output is ok It is represented by the female part of the coaxial connector, identical to the female part of the coaxial connector of a rectangular frame, a DC converter of 5 V of the computer system unit to a constant voltage, selectable within 9-12 V, an LED indicator of the supply voltage of the flicker-noise current generator, while the flicker generator noise current, DC voltage converter and LED indicator are located in a rectangular box, on the front side wall of which the named jacks are fixed the second part of the coaxial connector of the flicker noise current generator, and on the rear side wall of the rectangular box, the female part of the connector, through which 5 V is supplied to the DC / DC converter from the system unit, the first section of a two-wire cable ending in two identical cable parts of the connectors connected to the female part of the connector located in the lower corner of the rectangular frame, and with the socket part of the connector located on the front side wall of the box, and the second segment of the two-wire to blanching, the beginning of which terminates a cable plug USBA-SP, to be connected to an outer surface located on USBA-1J outlet system unit, and the end of the second segment of the two-wire cable ends of the cable connector part, a corresponding female connector part fixed to the rear side wall of the box. In the particular case, the second segment of the two-wire cable ends with a USBB-SP plug, and the USBB-1J socket mounted on the rear side wall of the box is used as the socket part for this plug.

While working on a computer, the FS of the MP is created on the upper part of the human body by an inductive coil located on the monitor, through which the current of the FS of the generator with an upper frequency of 100 Hz flows, while the magnitude of the magnetic field induction in the region of the human head at this frequency is selected within 0.2-0.5 μT, and the exposure time per person is from 30 minutes to 4 hours.

Tests of the device to reduce the negative impact of a liquid crystal monitor on a person were carried out on the basis of the Medical Center “Media Dunes” of Tomsk during 2012-2013. The study involved four people who worked continuously on a computer before moving to work in a medical center. The age of the subjects ranged from 32 to 54 years. The duration of one exposure of a patient to FS with a magnetic field ranged from 30 minutes to 4 hours daily. It included, in particular, typing on a computer keyboard and reading emails.

Examination of patients was carried out before the session of magnetotherapy and after its completion. It included: general examination, palpation and vertebral neurological examinations, assessment of neurological status, blood pressure monitoring, assessment of subjective complaints and the nature of changes in the electrical conductivity of the measurement points according to the R. Voll electro-puncture diagnosis method that occurred during the patient’s treatment. When conducting electropuncture diagnostics by the Voll method, the Deca-Voll apparatus manufactured by ZAO Dunes Medical and Environmental Center, Tomsk, was used.

According to the Voll method, the following indicators were monitored:

- an indicator of arm-arm branches, the norm corridor for which is within 82-86 conventional units (cu) and the tone of the autonomic nervous system according to the type of normotonia;

 - indicators on the meridians of control measuring points (CIT) of the lymphatic, vascular and nervous systems and epithelial-parenchymal degeneration (physiological norm corridor for these indicators is 50-65 cu);

- asymmetry of indicators at measurement points of meridians of the right and left hands (an acceptable difference of indicators - up to 10 cu);

- the phenomenon of “falling indicator”, reflecting a violation of the functions of the examined organs and systems (the norm of “falling indicator” is up to 5 cu).

The following are two examples of treatment of the proposed device for patients who have neurological pathologies.

Example 1

Patient 3., 52 years old. Complaints of tension in the eyes, pain in the cervical spine by the end of the working day with prolonged use of the computer. A preliminary examination of the patient’s neurological status before starting work on a computer revealed tension in the back muscles, limitation of mobility in the cervical spine, tenderness of the Erb points (bilateral). When examined by the Voll method, the indices on the meridians of the nervous system (the point of the cervical spine, the point of the vessels of the brain, the point of the brain stem) were 82 cu The points of epithelial and parenchymal degeneration of the organs of the head were within the general excitability (78 cu). The asymmetry of indicators was recorded on the meridian of nervous degeneration on the right and left. The tone of the autonomic nervous system belonged to the type of hyperergy (sympathetic type of innervation) with an overestimated rate of arm-arm assignments (88 cu). A study of neurological status revealed neurotransmitter disorders. The indicator on the lymphatic meridian - the point of outflow of lymph from the eyes - was in the zone of physiological stress (72 cu). After the third procedure of magnetotherapy, the index on the meridian of nervous degeneration decreased by 2 cu and was equal to 80 cu, and the indicator for leads arm-arm decreased by 2 cu (the initial indicator was 88 cu). The asymmetry of indicators on the meridian of nervous degeneration remained, but its fluctuations were within 8 cu After the fifth day of work on a computer containing the proposed device, the patient noted an improvement in general condition, a decrease in tension and pain in the cervical spine and collar region, noted a slight improvement in well-being and a decrease in tension in the eyes. The indicator on the lymphatic meridian (the point of outflow of lymph from the eyes) decreased by 2 cu. (up to 70 cu). Indicators for CIT of the meridians of nervous and epithelial-parenchymal degeneration after the fifth procedure were within the physiological norm - 65-70 cu (there was a significant decrease in the initial measurements). The patient underwent treatment and observation for 10 days. Subjectively, she noted a decrease in headaches and a decrease in tension in the eyes and neck. Neurological status after the end of treatment also had a positive trend. The tension in the muscles of the back and neck decreased, the range of movements in the cervical region increased, the eyeballs and Erb points were painless on palpation. Hand-arm leads, CIT of meridians of nervous and epithelial-parenchymal degeneration and lymph drainage from the eyes were in the corridor of physiological norm (66-68 cu). An objective examination of the patient and normalization of the indices on the CIT of meridians and arm-arm leads testified to the positive results of the use of FS magnetotherapy.

Example 2

Patient K., 32 years old. Complaints of headaches, sometimes accompanied by an increase in blood pressure, frequent emotional disturbances, pulling pains in the lumbar spine. The patient was observed at the gynecologist, status gravidities (pregnancy - 20 weeks). We spent 10 days monitoring the patient while working on her computer, on which the monitor was wearing the above frame. Initially, the indices on the meridian of nervous degeneration were 82 cu, on the meridian of the vascular system - 78 cu, lymphatic drainage from the eyeball - 80 cu, the value of the “drop indicator” - 6 cu, according to the leads of the arm -hand - 86 cu After the first day of working on a computer, the patient noted a slight improvement. The feeling of tension in the eyeballs decreased, but the indices of its CIT of meridians exceeded the upper boundary of the physiological corridor. After the fifth day of work on the computer, a decrease in indicators on the meridians of the vascular system to 72 cu was noted. and the lymphatic system to 76 cu, while at the point of outflow of lymph from the eyes, the indicator drop indicator decreased by 2 cu After ten days, the indicators were within normal limits on the CIT of the meridian of nervous degeneration (68 cu), on the meridian of the vascular system (66 cu) and on the leads arm-arm (82 cu). The patient drew attention to the fact that the headaches became less intense, the extraneous sounds were less annoying, and the tension in the eyeballs was less worrying. Her condition improved significantly, in particular, her blood pressure returned to normal.

All patients of the Media-Dune medical center who underwent treatment with the proposed device improved overall well-being, there was a decrease in the intensity of pain and tension in the eyes and back muscles, electro-puncture diagnostics on the studied meridians and arm-arm abductions improved, positive neurological dynamics .

Thus, the use of the proposed device as an addition to the liquid crystal computer monitor can reduce the number of human diseases.
