Description

DEVICE FOR MONITORING AND CORRECTION OF THE STATE OF THE FUNCTIONS OF THE ORGANISM

The inventive utility model relates to medical equipment, in particular to devices designed to control and correct the state of body functions, and can be used both in medical institutions and at home.

A known method of recording the impulse activity of peripheral nerves in accordance with the USSR author's certificate No. 1335257 with a priority of 11.29.79, used in the diagnosis and treatment of injuries and diseases of the peripheral and central nervous systems, as well as the musculoskeletal system and other organs.

A device for electrotherapy is known “AKSON-01 ZhTM3.857.483TU but the USSR copyright certificate No. 1410312 with a priority of 04/13/84, which implements the above method and carries out a dosed therapeutic effect on the patient.

The AKSON-01 device consists of a potential remote and zero plate electrodes, a direct current source, an amplifier, a pulse shaper, control units for positive and negative ampuluses connected to a light indicator. The specified device allows you to record the adaptive response of the body arising in the form of impulse activity to disturbance by direct current.

However, the disadvantage of this device is the inability to search for areas of influence on the surface of the patient’s skin in the absence of an impulse response of the body to disturbance by electric current, which occurs on the fingers and toes, as well as in case of violation of innervation.

IPC A61N 1 / 18.1 / 32.1 / 36, A 61V 5/05

operating mode switch, signal conditioner with output circuit, informative signs, light and sound indicators.

This device, in addition to recording impulse activity to a disturbance by direct current, allows you to additionally record the adaptive response of the body that occurs in the form of measuring the resistance of an organism when it is disturbed by a pulsating current. In the hom mode, the main informative sign is the time of the change in the frequency of the self-excitation of the amplifier, in the positive feedback circuit of which an area of the body with adaptively changing resistance is connected.

In both described modes of operation of the AKSON-02 device, the recorded signals provide reliable information about the state of the organ or its function and allow for the implementation of a dosed corrective effect for various diseases. It should be noted that the resulting resistance of the RC circuit is determined not only by the parameters of the circuit, but also by the equivalent resistance of the patient (between the potential and zero electrodes), as a result of which there is a fundamental possibility of monitoring and correcting the state of body functions, even in the absence of a pulse response body exposure to direct electric current.

The described electrical stimulator "AKSON - 02, is the closest to the claimed utility model in its technical essence and the tasks to be solved, therefore, the authors choose it as a prototype.

However, since the therapeutic effect,

the duration of the impact on the area of pathology, prototype device, according to the authors, has the following disadvantages:

The scheme for determining the end of the required exposure time does not automatically turn off the patient or device circuit, which, indicating the cessation of the change in the generator frequency, continues to generate a constant frequency. and, therefore, continues to affect the body, which can lead to an overshoot reaction;

- the scheme of the existing analogue indication does not automatically determine and remember the duration of exposure to a specific point, as well as the total exposure time, which is important as a diagnostic factor in the following procedures to evaluate the effectiveness of electrotherapy and change treatment tactics.

The purpose of the claimed utility model is to expand the functionality of the device by increasing the degree of automation.

a circuit, one of the elements of which is a portion of the patient’s body, a key block, a logic block, a memory block and a digital indicator are introduced, while the key block provides the ability to automatically disconnect the DC source and the feedback circuit of the operational amplifier from the electrodes on the patient’s gel on the basis of a logical unit that is connected to the output of the operational amplifier. In this case, the manual mode switch is duplicated by the automatic mode switching circuit at the command of the logical unit, the corresponding bits of the output register of which are connected to the input of the memory unit, and the output of the memory unit is connected to the input of a digital indicator.

The inventive utility model is accompanied by the following

phafic materials:

Figure 1 Functional block diagram of the proposed device;

Figure 2 - Equivalent electrical circuit of the input circuit and the feedback circuit of the operational amplifier;

The inventive utility model contains a potential electrode I, a bullet electrode 2, a constant current source 3, an operating mode switching unit 4, an operational amplifier 5 with an RC selective circuit 6, a key unit 7, a logical unit 8, a memory unit 9, a digital indicator 10

The connection diagram of the electrodes 1 and 2, as well as the current source 3 with a selective RC circuit to the operational amplifier 5 is presented in FIG. 2, and gives an idea of the operation of the key unit 7 and the mode switching unit 4, which is controlled by the operator or automatically by changing parameters of the RC circuit in such a way as to exclude the possibility of self-excitation of the operational amplifier 5.

The key unit 7 and the mode switching unit 4 convert the digital commands of the logical unit 8 into the corresponding relay commands for switching individual elements of the feedback loop of the operational amplifier, its input circuit and, accordingly, allow disconnecting the patient from the source of disturbance.

Logical block 8 is the main block that creates the main prerequisites for increasing the degree of automation of control procedures and correction of the state of body functions (compared to the prototype, where the analog circuit of the signal shaper for analog blocks of sound and light indication could not solve all problems without the active participation of the operator) . The digital circuitry of the logic unit, which assumes the presence of a clock generator in its composition, makes it easy to switch from the mode of simple fixation of informative signs indicating the completion of the adaptive reaction of the body (as in the prototype) to the mode of measuring the adaptive reaction time with automatic issuing of commands to switch the operating mode or Native disconnection of the patient circuit from the device.

Pa digital indicator 10 reflects current information during the procedure with the patient, and information stored in the memory unit 9 during the previous procedure and including the patient’s adaptive response to disturbance measured at several points as constant, pulsating, and pulsating current can also be displayed. , as well as the measured time of the total effect on the body, which can significantly expand the diagnostic capabilities of the device.

The output of information to the indicator 10 can be carried out according to the operator’s commands using an additional touch switch. The inventive utility model works as follows. The passive electrode 2 is taken in the hand or installed on the corresponding area of the patient’s skin, and in the area of the skin surface corresponding to the organ under investigation (Zakharyin-Ged zone), the potential point electrode 1 is changed and installed at an arbitrary point, while a constant or pulsating gok passes through it (in dependent and oi selected operating mode).

The inventive device has two modes of operation:

- in the first mode, the patient circuit is disturbed by a direct current of the order of 27 μL and the adaptive response time of the organism in the form of impulse activity is recorded;

- in the second mode, the patient circuit is disturbed by a pulsating current with a constant component of not more than 30 and a variable component of not more than 10 μA with simultaneous recording of the adaptive reaction time of the body by controlling the change in the frequency of self-excitation of the operational amplifier in the range of 800 Hz (normal)

1200 Hz (pathology).

The first mode of operation (control.i.ny)

In this mode (which is switched on by the operator or automatically by the operation mode switching unit 4 by changing the parameters of the RC target 6 in such a way as to exclude the possibility of self-excitation of the operational amplifier 5) when the zero electrode 2 is installed on the same and the potential electrode 1 touches the skin into the study area through the key device 7, a constant current of 27 μA is supplied from current source 3.

The organism responded to this disturbance with an adaptive reaction, expressed in the form of impulse signals. When the state of the key device 7 is turned on, these signals are fed to the input of the operational amplifier 5 and, from its output, to the input of the logic unit 8, where, after the selection of informative features, the received information is processed and digital signals are generated for the remaining units of the device.

-transformation of analog signals from the output of the operational amplifier 5 into a pulse and digital form;

-identification and analysis of informative signs corresponding to the operating mode;

-measurement of the adaptive response of the body;

- issuing a command to disconnect the device from the patient;

- issuing a command to the unit for switching operating modes 4;

-normation of the signal in amplitude and duration in such a way as to ensure stable operation of the memory unit 9 and the digital indicator 10.

Digital information from the output register of the logical unit 8 is sent to the memory unit 9, where a long-term storage of a number of diagnostic parameters is carried out in separate cells, including the time of exposure to specific points (at least ten) and the total time of exposure to the body for the entire procedure. The display of stored information can be carried out on a digital indicator 10 at any time after the end of the diagnostic treatment procedure and before the next. A digital indicator may contain a minimum (sufficient for accurate display) the number of digits of indication and a switch for alternately outputting information from the different cells of the first memory block.

Information about the end of the adaptive reaction of the body (the cessation of pulses to the input of the operational amplifier 5) from one of the bits of the output register of the logic unit 8 is fed to the digital control input of the key unit 7 to open the circuit of the DC source 3 passing through the electrodes 1 and 2, the body section the patient and the input circuit of the amplifier 5. At the same time, the same information is fed to the digital control input of the mode switching unit 4 (as a mode confirmation command).

The second mode of operation (main)

In this mode, when the passive electrode 2 is mounted on the skin and the potential electrode 1 touches the skin in the study area through the key device 7, a current source of 27 μA is applied from the current source 3 as well as in the first mode. A current with an amplitude of 10 μA is added to this current, arising in the self-excitation mode of the operational amplifier 5, covered by positive feedback in the frequency range 800-1200 Hz, implemented using an RC selective circuit 6. The TUK as a patient’s body turns on in series with the feedback circuit Since the operational amplifier 5 is connected, then all changes in the equivalent resistance of the body lead to a change in the frequency of self-excitation of the operational amplifier 5, and the adaptive response of the body is judged by a change in this frequency. The signals from the output of the operational amplifier 5 to the logical unit 8 are analyzed on

the subject of identifying informative signs. In particular, the cessation of changes in the frequency of self-excitation indicates the onset of the patient’s body adaptation to this disturbance, and the frequency of self-excitation characterizes the degree of approximation to the norm or pathology.

The storage and display of information on the length of time the adaptation to disturbance and the total time the nation ha acts on the body is performed in memory block 9 in the same way as it does, the axis in the first mode of operation of the device.

But at the end of the action of the pulsating current in the main mode of operation, the output of the logical unit 8 receives a command to the key device 7 for forcibly opening the patient circuit, then using the blocks 4 and 7 according to the commands of the logical block 8 (or according to the operator's commands), the disturbance mode is switched on continuously current (first mode) in order to assess the effectiveness of the therapeutic effect.

Clinical trials have shown:

-positive effect of the device on the immune and endocrine systems;

-the ability to correct the state of the body to compensate for the effects of harmful production and environmental factors, the ability to provide a strictly dosed effect.

The convenience of using the claimed utility model consists in increasing the degree of automation of one-time procedures and the course of treatment in general, and, therefore, in eliminating the possibility of overdose, which makes it possible to assess the state of functions and systems of the body in patients in an unconscious state, as well as in children. The inventive device is easy to use, trouble-free operation and has a long time of continuous operation.
