you electrostimulation of the muscles of the abdomen and uterus in animals with pathological childbirth (weak contractions and attempts, retention of placenta).

There is a method of delivery for animals (patent 3529154, C And 61 D 1/08, 1987), including the use of mechanical devices that must be installed a certain way on the body of the animal.

Also there is a method in which as a physical impact uses electric current for delivery in large animals (DE, application 3235666, C And 61 D 1/08, 1984).

The disadvantages of the known methods is the presence of pain, the appearance of the effect of addiction and relapse associated diseases, which reduces the efficiency of the methods.

The closest in technical essence to the proposed device is the invention of SU, ed. St. 480413, C And 61 D 1/08, 1975, containing electrode for insertion into the uterine cavity, the electrode for connection to the body, current-carrying conductors and the power supply with Elektroprivreda, and one of the electrodes is made in the form of a loop, and to introduce into the uterine cavity, the device is equipped with a device made in the form of a rod with holder for electrodes at the end.

A disadvantage of this device is that the pulses have the same impact amplitude and steep front, Rhone, in keeping in the uterine cavity foreign body negative impact on the state and behavior of animals, reducing therapeutic effect in the retention of placenta and causing complications in the postpartum period.

Using the proposed method improves the efficiency of the treatment in pathological childbirth in animals by eliminating the use of medication uterine means and operative intervention.

The technical effect is achieved in that in the method of electrical stimulation of contractions of the muscles of the abdomen and uterus in pathological births in animals, including pulsed electric effect on the organs of the animal, the effects of exercise on biologically active points of the uterus and ovaries on the body surface of the animal form and in the form of packs of monopolar pulses with a repetition rate of packets in the range of 0.1 to 5 Hz and with an amplitude and frequency modulations of the signal in each bundle at keystone law within respectively 0 100 50 505Hz, and the device for implementing this method, containing the electrodes connected to the respective outputs of the system formation, includes connected in series generator modulating the pulse is elitel monopolar pulses, the outputs of which are the outputs of the pulse-generating, while the output of the integrating circuit is also connected to the modulating input of the amplitude modulator.

According to the patent and technical expertise not found a similar proposal that allows to judge about its compliance with the criteria of patentability <inventive step>. Compliance with the declared object of the criteria of patentability and industrial applicability> due to the fact that electrical stimulation of contraction of the muscles of the abdomen and uterus are used in pathological childbirth pulse packet with keystone law changes the frequency and amplitude of the pulses in each bundle and the pulse frequency can vary from 50 to 105Hz, amplitude from 0 to 100, and the repetition rate of the packets in the range from 0.1 to 5 Hz, which eliminates the appearance of pain and increase the efficiency of medical care during childbirth.

In Fig. 1 shows a functional diagram of the device for electrical stimulation of contractions of the muscles of the abdomen and uterus in pathological childbirth in animals; Fig. 2 graphs explaining the operation of the device and its individual nodes.

I, as follows: the lead plates with a length of 100 to 200 mm, covered with cloth of gauze moistened with isotonic sodium serving as electrodes are connected by wires to a system output signal. The electrodes are fixed on two symmetric biologically active points of the ovaries and horns of the uterus on the surface of the animal's body located between the first transverse processes of the 2 3rd lumbar vertebrae, approximately midway of their length, the second at the intersection of the line connecting the sacral tuberosity of the Ilium and the sciatic hill and segmental line drawn from the greater trochanter of the femur to the crest of the croup) and is powered device. The biologically active points is the impact of packs (monopolar modulated pulses with keystone law changes the amplitude and pulse repetition rate, and pulse frequency in each bundle varies from 50 to 105Hz, amplitude from 0 to 100, and the repetition rate of the packets in the range from 0.1 to 5 Hz.

When exposed to such a signal on biologically active points is the contraction of the muscles not only cancer, but also the abdominal muscles. Since the frequency varies within wide limits, it is exposed as chalk is ikonicheskim resonance technique, where under the influence of broadband vibration resonance occurs, large and small details. Thus, Contracting the abdominal muscles and uterus of various sizes promotes better movement of the fetus and the early release of the uterus from fetal membranes.

Advantages of the method compared to known is the following:

1. Excitation reductions of abdominal muscles and uterus is only with the beginning of the natural contractions and alternates with relatively long intervals of rest, in addition, the excitatory impulses gradually grow and match, which eliminates completely the possibility of pain, correspond to the biological nature of the excitation, providing for physiological birth.

2. Excludes the use of the device for insertion of the electrode into the uterine cavity, thereby eliminating the drift of microflora in the body and its subsequent inflammation.

3. No negative side effects on the body of the animal.

4. Activating effect on the muscles of the abdomen and uterus helps smooth removal from the uterus of a fetus and the rapid expulsion of fetal membranes without operative and conservative interfering the deposits in animals the ability to insemination, fertilization and fruiting and prevention of infertility.

A device for electrical stimulation of contraction of the muscles of the abdomen and uterus in pathological childbirth in animals comprises a generator modulating pulses 1, the integrating circuit 2, the frequency-modulated oscillator 3, a differentiating circuit 4, the amplitude modulator 5, power monopolar pulses 6, the electrode 7.

Generator modulating pulses Ic R C specifies the chain generates rectangular pulses with a frequency of 0.1 to 5 Hz (if the R to use a variable resistor, for every animal you can find the optimal frequency of exposure). The generator output of the modulating pulses is connected with the integrating circuit 2. The signal from the integrating circuit 3 is supplied to a frequency-modulated oscillator 3 and the amplitude modulator 5. The frequency-modulated oscillator 3 is performed on chip and is controlled trapezoidal signal from the integrating circuit 2. First, the frequency increases (with increasing voltage "a-line"), then is constant (at the top) and decreases at the end of "the line" (signal 2, 4). The amplitude of these signals unchanged. Next, this signal is fed to the input of the differentiating circuit 4, where the decline of the front and rear edges of the pulse (this reduces the pain when the amplitude of the pulse).

"Pointed" signals from the differentiating circuit 4 (2, 4) and trapezoidal 2.2 signal from the integrating circuit 4 is supplied to two inputs of the amplitude modulator 5. In the amplitude modulator 5 "pointed" the input pulses of the same amplitude-modulated keystone law (while maintaining frequency and duty cycle), i.e., the first amplitude increases, then becomes constant and decreases at the end of the line. The output of the amplitude modulator 5, a signal is generated to 2.5. As the amplitude modulator 5 are chips with hinged elements.

The output signal of the amplitude modulator 5 is fed to the input transistor of the amplifier 6 monopolar pulses with variable gain. In the signal amplifier 6 increases of 2.5 unchanged and is supplied to the electrodes 7. Variable gain regulation output pulses is selected in the range of 0 to 100 (individually for each animal).

The device operates as follows. Generator modulating pulses 1 generates a sequence of rectangular pulses with a repetition rate of 0.1 to 5 Hz and the ratio of the repetition period of pulse 1 (signal 2,1). These pulses arrive at integal 2,2). Trapezoidal pulses with the integrating circuit 2 receives a frequency-modulated oscillator 3 and the amplitude modulator 5. Under the influence of trapezoidal pulses of 2.2 frequency-modulated oscillator 3 generates rectangular pulses of variable duty cycle, the frequency of which varies at keystone law in the range from 50 to 105Hz (signal 2.3). These rectangular pulses, variable frequency and duty cycle are served on a differentiating circuit 4. Using a differentiating circuit 4. Using a differentiating circuit 4 pulses of the frequency-modulated oscillator (signal 2.3) is converted into short pulses of fixed duration with the same keystone of the law of variation of the repetition rate (signals 2.4). The output pulses of the differentiating circuit 4 (2.4 signal) are fed to the amplitude modulator 5 modulates amplitude trapezoidal form (2.5) signal, (2.2) coming from the integrating circuit 2. Modulated signal (2.5) from the amplitude modulator 5 is fed to the input of the amplifier monopolar pulses 6. The amplifier 6 monopolar pulses enhances the sequence of modulated pulses (2.5) to amplitude equal to 100 (maximum cylinder is analnogo unit weight of 600 g As the hardware components are used chip MOS, transistors, etc. as a power source can be applied battery voltage 9 12 V or AC adapter with a separate transformer.
