Abstract

one . A method for diagnosing a functional state of the muscles, which consists in measuring their elasticity, in that, in order to detect abnormalities in the functioning of the neuromuscular apparatus, the oscillation frequency of the bioelectric activity of the muscles in the same the extent of the impairment is revealed on the area under study and on the healthy extremities and in terms of the ratio and measured values. 2. The device for diagnostics of the functional state of MOSH1TS, Sokholash; its elastic meter, having an indicator with an arrow, a lock of an arrow: an indicator, a linear displacement meter with a moving contact, distinguishes it from the fact that, in order to detect malfunctions neuromuscular apparatus, it contains electromyographic electrodes, a myograph and a synchronizer, the electrodes being a dielectric base with contact elements, between which there is an opening for a probe for measuring j elasticity, s directly but through a movable contact connected to the synchronizer myography. 1 (L to 4 th I I th 0.3 and.

Description

The invention relates to medicine, namely to neurophysiology, traumatology and orthopedics.

The purpose of the invention is the discovery of ijapy-neural in the operation of the neuromuscular apparatus.

 - FIG. Figure 1 shows the proposed device without a myograph, RPM (the first view; Fig. 2 shows the connection of the electrical circuits of the toniometer and the synchronizer. -10

The device contains an elastic meter, which has an indicator I with an arrow 2 connected by means of a gear 3 with a probe 4. The working end of the probe 4 is made of dielectric, 5 riik. Arrow 2 has a latch 5 in contact with gear 3 and connected to the relay bark. 6 toniometry. The device is also equipped with a linear displacement dispenser, made in the form of a movable contact moving through a fixed 8 located on the indicator 1. The movable contact 7 has the ability to interact with the fixed contact 9, 25 installed also on the indicator 1. The working end of the probe 4 is placed in the hole 10 made on the dielectric base 11 between the contact elements 12, which represent the JQ plate. Base P with contact elements 12 performs the function of electromyographic electrodes and is directly associated with a myograph (not shown).

The movable contact 7 is connected by means of an electric circuit of the tonometry with the synchronizer electric circuit, namely it turns on the synchronizer relay 13 via contacts 14 and 15. The synchronizer closes the circuit of the tape-recording mechanism 16 of the myograph, and also powers the voltage divider 17. The method is carried out as follows.

Synchronous registration is carried out 10 through 1; elastic and frequency oscillations of bioel (critical fitness of the same muscles in the same zone on the injured and healthy extremities) are calculated. The ratio of the elasticity of the mass of the biological activity of the biological activity on the each limb and compare with each other the coefficients obtained |

According to the degree of deviation (reduction) of the coefficient on the limb under study from the coefficient on the healthy limb, a violation of the function of muscle 1 is judged.

The device works as follows.

The probe 4 together with the base I1 and the contact elements 12 are pressed. to the body surface under study. When the probe 4 is immersed, the movable contact 7 moves along a stationary coupling 8 up to the stop in contact 9. At the same time, the electric circuit of the toniometer blinks through the relay 6. The anchor of the relay 6c with latch 5 is pulled to the core of the coil of this relay and is wedged by gear 3, fixing arrow 2. The position of arrow 2 corresponds to: elasticity of the muscle to be shed. At the same time, contacts 14 and 15 turn on the synchronizer relay 13, which closes the circuit of the tape drive mechanism 16 of the myograph. An electromyogram is recorded.

In addition, when the relay 13 is turned on, voltage divider 17 is recorded, which supplies the myograph amplifier with the signal of the mark of the measurement of Elasticity on an electromyogram.

Thus, the recording of an electromyogram occurs at the time of fixation of the arrow, indicating the value of elasticity in the muscle under study.
