Starting date of the patent: 1992.06.05
The invention relates to medicine, particularly to neurology and therapy, and can be used in the treatment of various diseases associated with vascular disorders vegetative, using biofeedback (BFB), and electrical stimulation.
The technical result - increasing the therapeutic effect due to the simultaneous exposure to the patient's self-regulating muscle relaxation and biofeedback controlled inactivation of trigger points with electric pulses with parameters close to the parameters of biological potentials of organs and tissues. Device for pain relief consists of two groups of electrodes, the first of which is the patient's muscular activity sensor, amplifier, integrator, which is connected to the threshold element, which is connected in series with the multivibrator, infralow frequency generator and the electrodes of the second group. Miosignalov indicator connected to the input of the threshold device.
DESCRIPTION OF THE INVENTION
The invention relates to medicine, particularly to neurology and therapy, and can be used in the treatment of various diseases associated with vascular disorders vegetative, using biofeedback (BFB), and electrical stimulation.
Known electronic devices, modulators for the treatment of migraine and corresponding methods comprising supply of percutaneous electronic waves between the electrodes mounted on the corresponding points, consisting of a high-frequency electric wave to the low frequency amplitude modulation.
A device for stimulating signal to attenuate pain in muscle tissue and its application. The device has three electrodes: active, passive and ground. In addition, two peripheral electrodes are connected with conductors of the control unit. The control unit enhances the electromyographic signal, converting it into a stimulating.
It is known electronic device and method of reducing the pain of migraine, comprising a modulator, generator and stimulating electrodes. The electronic device provides a percutaneous exposure to electrical fluctuations in the patient's body in order to combat the sensations caused by migraine.
The main drawback is the lack of the above analogs of biofeedback (BFB), which excludes the participation of the patient in the treatment process, but also the impact on the patient's pulses, the parameters of which do not correspond to biopotentials of organs and tissues of the body.
The closest to the proposed device is a device comprising a standard electromyograph indicator and a sound generator. A disadvantage of the known device is that it does not provide adequate therapeutic effect, as It does not decrease the excitability of the trigger points that cause pain or that other sites.
Thus, from the analysis of the related art revealed that the existing methods and devices provide lowering pain by biofeedback, relaxation of electrical stimulation. However, all these solutions have significant drawbacks, namely: all provide a low therapeutic effect due to the lack of impact on the terms that trigger painful muscle condition (trigger points).
The problem is securing increased therapeutic effect by inactivating trigger points.
The problem is solved by the fact that to achieve pain relief at the trigger points affect electrical signals with parameters close to the parameters of biological potentials of organs and tissues, while simultaneously arbitrary patient muscle relaxation using biofeedback. As the feedback signal miosignal.
A device for relief of pain, comprising series-connected between an amplifier miosignalov with sensors integrator miosignalov indicators further comprises connected in series a threshold device multivibrator infralow frequency generator and the electrodes, with the output of the integrator is connected to the input of the threshold device.
Threshold device provides the appearance of a signal at its output when a certain voltage at the input, which provides operation indicator light. Flicker employs subsonic frequency control of generator when the signal from the threshold device. Their impact on the relationship ensures patient biofeedback. The generator produces infra-low frequency signals infra-low frequency modulated by randomly amplitude and provides interaction with other elements of the device analgesia myofascial points and improving microcirculation in the tissues.
From the analysis of the current state of the art device is not detected, characterized by features identical to all the essential features of the proposed device. All features are essential and necessary to achieve the technical and therapeutic outcome. Thus, the proposed device of the invention meets the criterion of "novelty".
The newly introduced elements of the device are well known, but their relationship with the other elements of the scheme and interaction of all elements of the circuit using the device provides a new property inactivation excited trigger points. It is the simultaneous effect on the patient in two ways: self-regulating muscle relaxation by the patient under the supervision of biofeedback plus inactivation of trigger points using pulses with the parameters of biological potentials of organs and tissues is not only faster and for longer periods relieve the patient from pain associated with hypertonicity of muscles, but also normalizes his blood pressure that achieves an effective therapeutic treatment.
Hitherto property is ensured aforesaid known devices and have been identified and implemented by the author, that the inventive step.
For realization of the proposed apparatus use sufficiently known means as described in the application materials, those skilled average. You can use this device in practical public health, clinics, dispensaries, home. Thus, the apparatus is industrially applicable.
A device for pain relief consists of an amplifier miosignalov 1 sensor 2 (see. Figure). The amplifier 1 connected to the input of the integrator 3, which, in turn, connected to the threshold device 4. The threshold device 4 is connected to the input of the indicator light 5.
Example of specific operation of the apparatus when treating a patient. The patient is placed in a comfortable chair. The doctor determines the patient via localized pain and puts a pair of electrodes (2) of the device region on muscle pain (see. Annex to the application of FIG. 1), the second pair of electrodes (8) corresponding to the trigger point. Then given instructions what strategies to use for the voluntary control muscle tone. The patient was given an opportunity by meditating to find a functional condition in which the muscles begin to relax. When the device is registered electrical activity of muscles. Miosignaly with electrodes (2) via the amplifier (1) fed to the integrator (3), where they are converted and fed to a threshold device (4). When exceeding a certain threshold value, namely 25 + 1.2 mV, miosignal supplied to the indicator 5, i.e. is converted into a light signal and the multivibrator (6). LED (5) lights up, and the flip-flop (6) at the same time includes the infra-low frequency generator (7). With an increase in muscle tone frequency flashing indicator (5) increases. Patient anger management method achieves the most complete muscle relaxation, which is controlled by the indicator (5). Simultaneously, muscle relaxation is achieved by infra-low frequency oscillator (7), by which the conduct of appropriate stimulation of trigger points. Additional exposure to electric pulses with parameters close to the parameters of biological potentials of organs and tissues, by which is independent of the patient additional inactivation of trigger points, significantly increases the effectiveness of treatment and pain relief.
Thus, use of the device for relief of pain provides an effective effect on the body by the simultaneous action of biofeedback and electrical stimulation trigger points, and muscles, which leads to relaxation of muscles, improve microcirculation, analgesia myofascial points. This reduces and relieves pain, there is a persistent effect, reduced drug exposure. Self-powered, simple operation, portability allows you to use the device in any conditions.
