Description

The invention relates to medical equipment, namely to devices for implementing a comprehensive therapeutic effect: heat, magnetic field, vibration for the treatment of inflammatory processes, and can be used in the treatment of prostate diseases, and also can be used in proctology, gynecology, urology in the treatment of hemorrhoids, cracks rectum, certain gynecological diseases, impotence, sexual disorders, etc. both in a hospital and at home using the device by the patient.

A proctological device for treating internal and external hemorrhoids is known, comprising a cylindrical metal shell into which a resistive heater is inserted, consisting of a heat-insulating ceramic cylindrical core, a coaxial shell, and an electric coil wound around the core, the front end of the shell being connected to a temperature sensor, and the resistive heater - with a current source to which the regulator is connected (see US Pat. No. 4,227,535, A 61 F 7/12, 1981).

Such a device provides only thermal therapeutic effect and has a complex structure. In addition, the device does not provide the possibility of a subjective assessment of the temperature of the device.

A device for massage of hollow organs containing a massage element with a spherical tip, a shell, an active element mounted inside the massage element and connected to the drive, a handle, a circular annular permanent magnet with axial magnetization, rigidly connected with the handle, while the massage element is made in the form an elongated body of revolution with a wave-like generatrix, the end of which is mounted coaxially with the hole of the ring magnet in the handle with the possibility of axial reciprocating movement, along the gate and changes in their frequencies, and the active element is made in the form of a spring-loaded rod of non-magnetic material on which small ring magnets with axial magnetization are discretely mounted, while the end face of the massage element is spring-loaded relative to the handle (see RF patent No. 2071753, class A 61 N 21/00, 1997).

The device provides simultaneous mechanical, electrostatic and intense magnetic effects on areas of hollow organs. A disadvantage of the known device is the need for preliminary autonomous heating of the massage element to a temperature of 37-40 ° C, which is inconvenient in operation.

A device for therapeutic heat and massage effects with prostatitis containing a working part made in the form of an elongated hollow cylinder with a rounded end, a handle with a limiter placed coaxially with the cylinder, and a heater for the working part (see RF patent No. 2071753, class A 61 N 21 / 00, 1997).

The known device has a limited range of therapeutic effects:

- the simultaneous effect of massage (mechanical using a manual drive) and hyperthermia;

- hyperthermic effect.

In the known device, the working part is made in the form of a tube with a spherical tip, while the spring of the mechanism for moving the working part is placed in the housing, and grippers are installed on the housing.

A disadvantage of the known device is its low therapeutic effectiveness, due to the fact that during massage the working part of the device acts with a spherical tip only on a limited area of the prostate gland, while the longitudinal movement of the working part does not create sufficient radial forces that contribute to enhanced secretion removal through the output channel. In the known device, it is extremely difficult to smoothly, without jerking, the effect on the massaged organ and it is almost impossible to reproduce the conditions corresponding to the most effective finger massage. In addition, the known device has a rather complicated design due to the presence of a movement mechanism, a protective casing, a locking ring, which leads to a decrease in the operational reliability of the device and an increase in its cost. The presence of a large number of parts makes it difficult to conduct reliable sterilization of the device, especially when used at home.

A device for therapeutic heat and massage effects with prostatitis, containing the working part, made in the form of an elongated hollow cylinder with a rounded end, a handle with a limiter, placed coaxially with the cylinder, and a heater for the working part, and the working part and handle are made in the form of an integral sealed unit with an internal cavity in which the heater is located, made in the form of an electric heater attached to the terminals placed on the end plane of the unit, while the section adjacent to ending, made with a thickening of a flattened ellipsoid shape and has a length of 25-35 mm, and the handle is made with a wavy outer surface, while the distance between the peaks of adjacent waves is 20-22 mm (see RF patent No. 2119787, A 61 N 21700, 1998 )

The main disadvantage of the device is the limited number of modes of physiotherapy (thermal or manual massage or massage) and the need for manual massage. Another disadvantage of the device is the insecurity of its use due to the fact that during massage the reciprocating movement of the device is carried out by the hand holding the handle with the current lead. This reduces the reliability of connecting current-carrying conductors to the terminals and / or increases the likelihood of their breaking. The need to reliably hold the device with all the fingers located during the massage in the wave-like recesses of the handle makes the handle cumbersome, which increases the dimensions of the device.

A device is known for treating inflammatory processes with hyperthermia, comprising a housing consisting of a working part with a thickened end and a distal end as a handle, located inside the housing and connected to the electric power supply unit, a heating system, an electric heater, a bearing element made of non-magnetic material and located inside the housing along its axis with deepening into the body of the distal end (handle) of the housing, while the areas of the heater and the housing are selected from the ratio Sн = (0.5-1.1) Sk (see RF patent No. 2092137, A 61 F 7/12, pu Bl. 1997).

The known device provides a limited range of physiotherapeutic effects: hyperthermic effects; simultaneous exposure to a pulsed magnetic field and hyperthermia; exposure to a pulsed magnetic field.

Closest to the technical solution is a device for a physiotherapeutic effect on body tissues for treating inflammatory processes, comprising a housing, a handle, a current lead element, an electric heater, a supporting element with an installed shock element, a spring, the housing having a working surface with at least one convex part for vibration massage (see RF patent No. 2224485, A 61 F 7/12, A 61 N 2/00, A 61 H 23/00, 2004 - prototype).

The main disadvantage of the device is the low transmission coefficient of the dynamic shock impulse directed along the axis of the bearing element from the surface of the convex part of the working to the inner surface of the patient’s body.

The inventive device solves the problem of increasing the effectiveness of treatment by increasing the intensity of massage, for example, the prostate gland.

The technical result of the invention is to increase the therapeutic efficiency of the device due to the formation of a dynamic shock pulse in the direction of the bevel surface of the working part of the housing.

The technical result is achieved by the fact that in the device of physiotherapeutic influence on the tissues of the body cavities containing the body, including the working part with a bevel, a handle, a current lead element and made of plastic mass, which fits the heating system located in the body of the body, the electric heater of which is made in the form of a winding connected through a current lead element with an electric power unit and placed on a supporting element located inside the housing with a recess in the body of the handle of the housing and made in the form tubes of non-magnetic conductive material with a spring-loaded shock element in its cavity formed between the fixed element fixed in the tube and the restrictive sleeve, the shock and fixed elements are located in the bearing element with the formation of an angular gap between their end surfaces and are configured to change the size of the specified gap during impact towards the bevel surface of the working part of the housing.

Preferably, the percussion element is made with a hole and springed with an L-shaped wire element, the short and long parts of which are placed respectively in the hole of the percussion element and along the inner surface of the bearing element under the bevel surface of the working part of the housing.

It is advisable in the working part of the body to bevel with an angle of not more than 2 ° on a length of not less than 35 millimeters.

It is preferable to perform the shock element with a bevel end face at an angle from 94 to 96 ° to the longitudinal axis of the housing, with the end face of the stationary element positioned orthogonally to the specified axis.

When conducting patent research, no solutions were found that are identical to the claimed, and therefore, the proposed solution meets the criterion of "novelty." The invention does not follow explicitly from the known solutions, therefore, the proposed invention meets the criterion of "inventive step".

Figure 1 shows a device for the treatment of inflammatory processes, top view; figure 2 is a longitudinal section EE of the device of figure 1; figure 3 - heating system; 4 is a spring-loaded shock mechanism; figure 5 - location of the shock element relative to the fixed element.

The device for physiotherapeutic effects on body tissues for the treatment of inflammatory processes comprises a housing consisting of a working part 1 and a handle 2 (Figs. 1, 2), separated by a physiological fixation device 3 made in one piece with it during treatment, made in the form of symmetrically located protrusions .

The heating system includes a supporting element 4 located along a longitudinal axis inside the housing and buried in the body of the handle 2, an electric heater 5, which performs the function of a control winding (from an insulated elastic electric wire) placed on the supporting element 4, and an electric power supply unit (not shown ) performed by pulsed. The body of the casing fits tightly around the electric heater 5 and is made of plastic material, for example, plastic compound of grades IO-45-12, PUE-85N or high-pressure polyethylene of grade 158. In this case, the areas of the heater and the housing of the working part are selected from the ratio Sn = (1.5-2 ) Sk.

The supporting element 4 is made in the form of a tube made of a material not influencing the magnetic fields to exclude the electromagnetic effect of the electric heater 5 on the shock and fixed elements 6 and 7, including brass, with a freely installed shock (movable) element 6 in its cavity formed between the fixed in the tube fixed element 7, and the restrictive sleeve 8.

Impact element 6 (Fig. 4) is spring-loaded with a spring 9 in the form of a L-shaped wire element made, for example, of brass wire, the short part of which enters the hole 10 of the impact element 6, and the long part is located along the inner surface of the bearing element 4 with a stop its end to the specified surface and the surface of the restrictive sleeve 8. The impact element 6 has a bevel end face at an angle from 94 to 96 ° to the longitudinal axis of the housing, while the end face of the stationary element 7 is located orthogonally to the specified axis (Fig.3, 5).

The shock element 6 with the spring 9 is placed (figure 2) under the surface 11 of the bevel of the working part 1 of the housing for the formation of impacts in the direction of the specified surface 11. The bevel of the working part 1 of the housing is made with an angle of not more than 2 ° at a length of not less than 35 millimeters. While the shock and fixed elements 6, 7 are located in the supporting element 4 with the formation of an angular (wedge-shaped) gap (α ° -90 °) between their end surfaces and made with the possibility of changing the size of the specified gap during impacts in the direction of the surface 11 of the bevel working parts 1 of the body.

The device operates as follows. Preliminarily, the case is sterilized by any known method, for example, by washing in a disinfectant solution. Before starting the procedure, the device’s electric power supply unit is connected to a power outlet and the electric heater 5 starts to release thermal energy that is transferred from it to the surface of the working part 1 of the body, the surfaces of the physiological fixation tool 3 and the handle 2. The required temperature of the working part 1 of the body is set. The working part 1 of the body is placed in the cavity to be treated, while the specified tool 3 provides physiological fixation and is a limiter of the position of the working part 1 in the cavity.

A voltage pulse is supplied to the electric heater 5 from the output of the control circuit (not shown), while different-polar magnetic fields are induced on the stationary element 7 and the shock element 6, tending to close them, overcoming the force of the spring 9. The rotation of the shock element 6 occurs with acceleration increasing with decreasing the gap between it and the fixed element 7.

The bevel angle α ° of the impact element 6 is in the range from 94 to 96 ° (see figure 5). Given that R1 <R2, then L2> L1, and

L1 = πR1 / 180 ° (α ° -90 °),

L2 = πR2 / 180 ° (β °),

where R1 is the radius equal to the segment between the points μ and κ,

R2 is the radius equal to the segment between the points μ and φ;

L1 is the value of the arc segment formed by the movement of the point κ when turning around the point μ by an angle (α ° -90 °);

L2 is the value of the arc segment formed by the movement of the point φ when turning around the point μ from the initial position of the shock element 6 until it contacts the inner surface of the bearing element 4;

β is the angle of the sector of the circle formed by the radius R2 and the value of the arc segment L2 (is the angle of rotation of the impact element 6).

From the foregoing, one can easily find the range of the angle of rotation of the shock element 6. Fulfillment of this condition leads to the fact that the point φ of the shock element 6 hits the inner surface of the bearing element 4. In this case, a microposition towards the surface is formed perpendicular to the longitudinal axis of the working part of the housing 1 the patient’s body. When the voltage pulse is removed, the force of the spring 9 opens the stationary element 7 and the impact element 6, while the impact element 6 with the point φ returns to its original position.

Due to the fact that the magnetic circuit formed by the fixed element 7 and the shock element 6 is open, the described process is accompanied by the appearance of a pulsed magnetic field. The passage of control current pulses along the control winding of the electric heater 5 simultaneously leads to heat generation in the winding. The operation of the device is accompanied by the release of heat associated with power losses: magnetization of the control winding (magnetic circuit), heat generation on the specified winding. The required temperature value on the surface of the control winding is determined by the amplitude and duty cycle of the control current pulses.

The duration of the procedure is prescribed by the doctor. During the procedure, the patient himself can control the temperature of the body according to the subjective perception of heating by the skin, mating with the inclined surface of the physiological fixation means 3, or by feeling the handle 2.

Physiotherapeutic effect for the treatment of inflammatory processes using the claimed device is as follows. The doctor determines the number of procedures and their duration.

The course of treatment when exposed to magnetotherapy, vibration therapy and hyperthermia is carried out for 7-9 procedures lasting up to 30 minutes, while vibration therapy is carried out with a periodically changing frequency from the frequency range from 25 Hz to 100 Hz, respectively, with values of the amplitude of magnetic induction from 5 mT to 50 mT and hyperthermotherapy in the temperature range from 30 to 45 ° С.

The immersion of the working part in the treatment of, for example, prostatitis is carried out until reliable contact of the working part with the mucous zone close to the prostate gland is obtained. Vibration massage is carried out, directly affecting the mucous membrane of the cavity with vibration, while there is an internal blood flow to the massaged area. Microdisplacement of the working part 1 is transmitted to the peripheral part of the prostate gland and secretion flows out through the urethral output channel. Thus, when conducting massage with the proposed device, the secretion is extruded simultaneously into the urethral canal. The duration of the massage is usually 8-10 minutes. During the massage, the thermal effect on the prostate gland is simultaneously carried out. In the process of using the device, a complex effect on the inflamed organ is carried out: mechanical massage, thermal effect and exposure to a magnetic field. At the end of the process of magnetotherapy, the working part of the body is removed from the rectum, and the body is sterilized.

Prototypes of the therapeutic magnetomassage device for prostatitis successfully passed clinical trials. As a result of tests, it was found that patients easily master the technique of using the device for treatment. The device provides high therapeutic effectiveness, reducing pain, improving overall health. The proposed device for therapeutic magnetotherapy for prostatitis can significantly increase therapeutic efficiency due to the fact that during the treatment of micromotion of the working part of the body affect a large area of the prostate gland, while the overall dimensions of the working area of the applicator do not change. This is because in the known device vibration was transmitted only by the convex part of the working surface of the applicator, and in the proposed device, the entire working surface exerts a vibrational effect on the prostate gland.
