The invention relates to the field of medical equipment, namely to physical therapy devices, and is intended for therapeutic effects of pulsed magnetic field (MT) on pathogenic zones in the walls and surrounding tissues open (available for insertion of the magnetic inductor without the use of tools) body cavities in gynecology, urology, proctology, dentistry.Widely known numerous designs magnetotherapy apparatus, creating a constant or variable MP. Their characteristics are different values of the magnetic induction (B), frequency (f), distribution In space, the nature of the change In time (t). Typical situations in which the most effective is the treatment of the alternating magnetic field gradient, area therapeutically significant values to near the magnetic inductor (hereinafter inductor) is comparable with its transverse dimensions. Therefore, if a localized pathological region is in the depth of the body away from its outer surface, the effect of the inductor that is located outside the body loses its effectiveness. In gynecology, urology, proctology, dentistry introduction of the inductor inside the open cavity of the body resolves this contradiction. However, there are currently no magnitotelluricheskie devices, design of inductors which would intracavitary, such as vaginal or pryamokishechnye, the impact of MP on the pelvic organs.Known apparatus for RF patent N 2074684, class a 61 F 9/00, a 61 N 2/00, selected as a prototype, which, like the proposed apparatus, made in the form of a cylinder, inside which is placed a motor drive. The device is equipped with a magnetic brake and a screen that provides a therapeutic effect unipolar pulses MP.The disadvantages of this apparatus is intended for use in ophthalmology, in particular, the impossibility of its introduction on adjustable depth into the open cavity of the body. Another disadvantage is the fixed pulse repetition rate and the inability to change the pulse shape.
, the better addressing technological simplicity, rather than biological feasibility. A significant part of the equipment creates or varying sinusoidally with time with the industrial frequency (50 Hz) MP or a sequence of unipolar bell pulses MP, following one after another at regular intervals.Meanwhile, as revealed in recent years, broadband varying the pulse repetition rate during the treatment session, as well as the ability to change their forms to create optimal conditions for selecting the most effective treatment regime applied to pathologies of various kinds. Thus, results of experiments and clinical studies have proved more effective than rectangular or trapezoidal pulses MP with different length front and back edge. Even more effective two-pole asymmetric pulses of complex shape, such cardioembolism. In recent years, the General advantages of devices with a wide range of frequencies or time-varying frequencies follow the same pulse MP.The technical result of the present invention is the construction of magni body, creating a gradient pulse MP in the area of pathology and its surroundings with changing during the treatment session, the pulse frequency. Rotating inside a protective casing shaft inductor with attached permanent magnets rigidly connected with the drive shaft, generates an alternating pulse MP. The design of the inductor allows you to change depending on the location and nature of pathology in the form of pulses MP.The technical result is achieved by selecting the shape and size of the magnetic inductor, the presence of a stopper for regulating and fixing the coil length and a programmable control device in the drive apparatus providing the possibility of creating a gradient pulse MP is changing over treatment frequency. The frequency may change during therapeutic session for a given program monotonically or rhythmically. The variation of the pulse shape is achieved by changing the shaft of the inductor to another (with a fixed another set of permanent magnets).If you enter the cylindrical system of coordinates and to align the axis of the system with the axis of the shaft of the inductor, each group of permanent magnets in the set, located in the ring is the profile of the pulse MP. Group number i corresponds to the coordinate zigroup i+1 - zi+1. In the case when the adjacent rings of the same, are formed of the same along the z profiles of pulse MP. If group i is different from group i+1 the number of permanent magnets distributed across the corner within the ring, you can create multi-frequency fields with f = f(z) and fields with different profiles of pulse MP.In this design, the amplitude of the field decreases with increasing r, i.e. as the distance from the surface of the inductor, and the radial gradient is close to the value of dB/dr = Bm/ and Rto. Here Bm- induced near the maximum inductor value resulting from the superposition of the fields of permanent magnets; - the characteristic size of permanent magnets, Rto- radius of the inner casing of the inductor.Frequency pulse MP is determined by the speed of rotation of the shaft of the inductor. The frequency may be constant or may vary during the treatment session, monotonically or rhythmically. The variation of the pulse shape is achieved by replacing the shaft inductor with one set of permanent magnets on the other with a different set of magnets.The proposed device enables vozdejstvovatj pulses during a session with the most effective form of pulses to the area of the pathological state of the tissue of the open cavities of the body.It is essential that the structure of the apparatus includes a shaft inductor with a fixed permanent magnet. The total number of permanent magnets m satises m > 1, and the maximum characteristic size of the permanent magnets in the radial direction must not exceed the inner radius Rtothe casing of the inductor. Groups of permanent magnets on the surface of the shaft of the inductor in the z-direction must correspond to the location of foci of disease.Another significant feature of the invention is the ability to control fixed length of the magnetic inductor entered into the open cavity of the body, using a special bracket. This is also achieved according to the locations of the permanent magnets location of foci of disease.The essential feature of the invention is the incorporation in the apparatus of the programmable control unit that generates the operation mode of the apparatus with a rotational speed of the motor shaft, changing during therapeutic session monotonous or rhythmic law.Another significant feature of the invention is that the shape of each permanent magnet, their total number is Adelaide in accordance with the requirements of therapeutic methods based on specific characteristics of the disease.In Fig. 1 shows in section a variant of embodiment of the device according to the invention. In Fig. 2 - form pulse MP at some point And in the case of a single permanent magnet.

Here, as an example, the magnetization of one of the permanent magnet 16 is equal to G, and the other 17 twice. The resulting pulse shape is shown in the right part of Fig.3.An example of using three permanent magnets is illustrated in Fig. 4. Here two permanent magnets 18 and 19 are equal in magnitude and opposite in direction to the magnetization (G), and the third magnet 20 is magnetized to 2G. The graph in the right part of Fig. 4 shows that the possibility of varying the shape of the pulse MP is large enough.Fig. 5 shows how decreasing the angular distances shall be established one more time and closer to a rectangular or trapezoidal shape 21.In Fig. 6 shows graphs illustrating implemented by the apparatus of options for changing the pulse repetition rate of the MP during the session. It is monotonous 22 and rhythmic 23 modes. Graph 23 as an example, the number of monotonic sections n = 3.The apparatus according to the invention operates as follows. Depending on the type of disease, the size and localization of the pathological area is chosen and connected with the shaft drive shaft of the inductor with the corresponding magnetization, the magnitude and location of the permanent magnets.
