The invention relates to medicine, namely to the device, allowing to determine Logie, urology, intended for the diagnosis of health status before and after treatment, and for prevention and treatment of inflammatory and other diseases.

Known pacemaker Stimulus-1 (see passport "Stimulus 1", Central Bureau of scientific and technical information of the medical industry.), containing the generator, the driver of the modulating signal, the modulator and the power amplifier.

The disadvantage of this pacemaker is the design complexity and large size. In addition, the pacemaker cannot be used for stimulation of hollow organs without completion of a design.

Known electroanalytical "Mirabel", , Izhevsk, THE 92-0201005-88 ART OP-78-01-7041 0/803) containing the generator current, active and passive electrodes, which are fixed at points on the body, depending on the hearth sick syndrome.

The known device, taken as a prototype, is used as a stimulant affecting the current through the skin. It may not be used for electrical stimulation of the mucous membrane of hollow organs with increased sensitivity to the action of electric current. In addition, the known device does not allow to control the pacemaker, including the generator current regulator current, active and passive electrodes, put the mode switch and the current amplifier, the current regulator is made in the form of the attenuator, and the active electrode includes a tube made of optically transparent material, the temperature sensor in the form of a transistor in a metal case mounted on the end of the tube, and the electrostimulation electrode coupled to the housing of the transistor, through the mode switch connected to an active electrode with the output of the attenuator and the electrodes of the transistor with a current amplifier output.

The advantage of the proposed pacemaker and electrotermometry is its high sensitivity to temperature, the linearity of the scale of temperature, the temperature sensor allows direct contact with the mucous membranes of the investigated organ. Besides this advantage is the possibility of sterilization by this construction, by any means, gas, chemical or cold (treatment of alcohol or other sterilizing compositions according to approved for this scheme methodology). This is possible due to the tight structure of the active electrode, is shown in Fig. 1, the construction is simple, easy to judge the mustache-temperature sensor, is introduced into the cavity of hollow organs, in particular in the body of the uterus, which allows for simultaneous electrical stimulation and temperature measurement of hollow organs, thereby controlling the procedure of the electrical stimulation. And depending on temperature-driven plot of corrected modes of electrical stimulation.

In Fig. 1 shows a General view of the active electrode of the pacemaker in the section, Fig. 2 is a circuit diagram of the pacemaker.

The active electrode of the pacemaker includes a housing 1 (Fig. 1) made in the form of a tube of optically transparent material, the temperature sensor in the form of transistor 2 in a metal casing that is installed at the end of the tube, and connected with the body of the transistor 3 (Fig. 2), the electrode 4 of the electrical stimulation. The active electrode is connected to the mode switch works 5. The emitter of transistor 6 is connected with the first base of the transistor 7. The second base of the unijunction transistor 8 is connected to the housing 3. The emitter of transistor 6 and the first base 7 is connected to the second wire of the switch 5. One of the outputs of switch 5 is connected to the attenuator 9, which in turn is connected to the output of the pacemaker 10 that represents the current generator. Vtorogo syndrome. For example, in Fig. 2 the second electrode is connected to crestomanci area of the patient. Two other output of the switch 5 is connected to the input of the current amplifier for temperature sensor 11 (hereinafter - the current amplifier).

The device operates as follows. The active electrode (Fig. 1) is introduced in the study of hollow organ such as the uterus), turns on the current source, the green light of the device. The mode switch 5 (Fig. 2) is translated, for example, to position "a" for the stimulation of a hollow organ, the temperature-driven body is not measured. For temperature measurement without procedures electrical switch means in position "b". For simultaneous measurements of temperature and electrical switch 5 is switched to position "c".

When the electrical stimulation may be used as unipolar and bipolar current signals of the electrical stimulator 10. The frequency of the current pulses (10.2) kHz, pulse duration (0.80.3) MS, and the amplitude of the output voltage varies from 0 to 20 - 40 B.

The amplitude of the output voltage of the pacemaker depends on the resistance of the tissue of the body (the land, so it is more and novorojdennym switch from 0 - 4B 4 - 8B, and so on up to 36 - 40V and smoothly control knob on each selected range. An additional step switch and regulator mounted attenuator 9.

In a humid environment for just the first five ranges, because the resistance of the tissue is small, and therefore, it requires a very small voltage amplitude.

Mode "a", "b" or "c" is selected by the switch 5. Selecting the mode of operation of the switch 5, set the control knob to the desired amplitude of the output voltage. It is determined at the beginning of a small tingling tissue.

Simultaneously with the electrical stimulation in the mode "c" of the switch 5, the voltage from the temperature sensor, representing the p-n junction of the transistor 3 is supplied through the switch 5 to the current amplifier 11.

The output of the current amplifier 11 may be connected to the recorder (if necessary), allowing you to record to tape a writing instrument of the character of change of temperature during the procedure.

Possible 3 mode:

- simultaneous measurement of temperature and electrical stimulation,

- stimulation without temperature measurement,

only ismerosom current active and passive electrodes, characterized in that it introduced a mode switch and a current amplifier, the current regulator is made in the form of the attenuator, and the active electrode includes a tube made of optically transparent material, the temperature sensor in the form of a transistor in a metal case mounted on the end of the tube, and the electrostimulation electrode coupled to the housing of the transistor, through the mode switch connected to an active electrode with the output of the attenuator and the electrodes of the transistor with the output of the current amplifier.
