Description

The invention relates to medical equipment, and can be used in physiotherapy and sports medicine, medical rehabilitation of patients with impaired and damaged musculoskeletal system, the consequences of lesions of the central nervous system, etc.

Known devices measure electrodermal indices, the main point of which is reduced to electro-puncture, polyzonal electro-skin examination of resistance (electro-puncture diagnostics) and skin potentials (EEG, ECG, ENMG) [RF patent No. 2252 692]. Also, many devices and apparatuses for electrotherapeutic effects, have fixed time parameters of exposure pulses, which is not always convenient for an individual approach [RF patent No. 2355437, RF patent No. 2294773].

Of the known technical solutions, the closest in purpose and technical essence to the claimed object is a device for electrotherapy, containing sections of the power source, designed to supply a given direct current to other sections of the device after rectifying the voltage of the AC network using a bridge, pulse generation section, designed to generating high-voltage signals with a given generation frequency supplied to the bipolar output sections after setting the pulse generation frequencies, bipolar output sections, made with the possibility of selecting poles due to the switching operation after amplification of the signals coming from the output of the pulse generation sections, and a working time control section with an alarm function, in which a power supply section and a pulse generation section are provided for each pole, and each of the output terminals of the bipolar output sections are equipped with a resistor and a triangular pulse generator to eliminate the short circuit that produces electrotherapy in order to equalize the measurement nny parameter (prototype) [RF patent №2288750. IPC A61 N 1/32. Publ. 12/10/2006, Bull. No. 34].

The claimed invention and prototype have the following common technical features: modes of electrotherapy through a group of conductors with electrodes with galvanic isolation.

The claimed invention differs from the prototype in the following.

The device works and is controlled only from a personal computer (PC) or tablet via a USB connector using a flexible connecting conductor. The device does not need an additional power source. The power circuit and data transfer are galvanically isolated, which does not require additional grounding. The software, information base, and work history are stored in the device’s independent flash memory. All operating modes of the device are indicated by LEDs located on the top panel with sound. The device is made in a plastic case, shielded from radio interference, mobile, lightweight, compact. Multifunctionality is laid for various research methods.

The disadvantages of the prototype is that all prototypes are limited by small functional tasks, that is, methods of measuring electric skin resistance, including with electrotherapy mode, other devices measure potentials (EEG, ECG, ENMG) for diagnostic purposes. Another drawback is the need for additional power supplies and grounding.

In the present invention, the disadvantages of the prototype are eliminated as follows. The proposed device combines the measurement of electric skin resistance and skin potentials with a customizable electrotherapy function, recording the dynamics of resistance changes during electrotherapeutic treatment.

The analysis of the prior art, including a search by patent and scientific and technical sources of information and identification of sources containing information about analogues of the claimed invention, allowed to establish that the applicant did not find an analogue characterized by features identical to all existing features of the claimed invention. The definition from the list of identified analogues of the prototype, allowed us to identify the set of essential in relation to the perceived by the applicant technical result of the distinguishing features in the claimed device set forth in the claims. Therefore, the claimed invention meets the condition of "novelty."

To verify the compliance of the claimed invention with the condition "inventive step", the applicant conducted an additional search for known solutions. The search results showed that the claimed invention does not follow for a specialist explicitly from the prior art in the implementation of such devices, and, therefore, meets the condition of "inventive step".

The inventive device is a hardware-software complex that operates as in a diagnostic mode, measuring the electrical skin resistance (Ohms) and potentials (mV) on the skin surface in physical units using contact electrodes, according to the so-called "large" leads, which include electro-puncture diagnostics assignments: “arm-arm”, “arm-head”, “arm-leg”, “leg-leg” and other segments of the body, and in the therapeutic mode of electrotherapy through contact electrodes in the area of detected distortions of the measured parameters.

The essence of the claimed invention lies in the fact that a device for diagnosing and correcting the functional state of a person has been developed, consisting of: a host processor unit, a pulse forming processor, a current modulation processor, a current source unit for micropolarization from 0 to 1 mA, and a current source from 1 mA to 50 mA, current switching relay block, resistance and potential difference diagnostics block, electrode switching block, power supply, internal flash drive, galvanic isolation unit, ind parameters, characterized in that a serial computer is connected in it, the input of which is connected to the device, power is supplied from the USB port of the computer through the USB 2.0 mini USB data cable, with a set of electrodes and a computer program running from the media’s own flash drive requiring installation on a PC running Windows-7 and higher, three processors on programmable microcontrollers that control the measurement modes of electrophysiological parameters, formation modes parameters of therapeutic currents and switching measurements and effects on seven channels, a block of light indication of the operating modes of the device.

The diagnostic mode is used to collect parameters of skin resistances and potentials with the construction of a surface diagram of indicators measured in areas of interest. In the operation of the Device, a computer program was used (certificate of state registration of the computer No. 20155611459 of January 29, 2015). Depending on the obtained results of resistances and potentials, the device can produce a flexibly adjustable electrotherapeutic mode in the desired zone or area of the patient, without removing the measuring electrodes. The device contains all the main types of electric currents used in physiotherapy for galvanization, electrophoresis, myostimulation, neurostimulation, micropolarization, etc. The possibility of forming their own electrotherapy programs has been introduced.

The ability to create individual settings for current therapeutic impulses or pulse packets with four time dependencies, hereinafter the templates Figure 2, 3 with times T1, T2, T3, T4, not counting the main therapeutic exposure time from 1 to 20 minutes. In the macrotherapy mode (mA), a current from 0.2 mA to 50 mA is formed; in the microtherapy mode (μA), a therapeutic current from 0 to 1 mA is formed. The electrotherapeutic mode in the treatment procedure automatically stabilizes the current and current parameters with the construction of a resistance graph during electrotherapy on current electrodes, reflecting the effect of biological feedback. An archive of data is generated with the results and parameters obtained, with the ability to print data.

All decisions on measuring parameters, electrotherapeutic treatment and control measurement of parameters are reduced in one device, without removing the patch measuring electrodes from the patient and reinstalling them.
