Description

 The invention relates to medical equipment, namely to devices based on the principles of the effect of a traveling magnetic field on the human body, and can be used in physiotherapy departments of hospitals and clinics, in medical research centers, and also used at home.

 Currently, devices for exposure to a magnetic field on biomedical living objects are known and are widely used.

 A known magnetotherapeutic apparatus (Auth. Certificate. USSR N 826587, class A 61 N 2/02, 1972), providing exposure to a rotating magnetic field on the body as a whole. The effect of a rotating magnetic field is obtained due to the mechanical switching of the windings of the magnetic field source, made in the form of a sector of the electric motor.

 The disadvantages of the known device are large dimensions, high cost, the inability to use at home.

 A device is also known for applying a magnetic field to biological objects (Auth. St. USSR N 697131, class A 61 N 2/04, 1975). The device contains a pulse generator connected through a pulse distributor to sections of the solenoid. The rotating sections of the solenoid create a pulsed moving magnetic field that affects a biological object.

 However, in this device there is no adjustment of the duration of the exposure pulses, there is no control of the operating mode of the device and the operability of individual sections of the solenoid, which reduces the effectiveness of the magnetic field on biological objects. In addition, the known device has large dimensions and weight.

 The objective of this invention is to provide a device for exposure to a pulsed magnetic field on the human body, which provides high efficiency due to the creation of a pulsed traveling magnetic field by electrical switching current coils, which are nodes of exposure to the human body, with the minimum dimensions and weight of the device, as well as its low cost.

 This problem is solved in the device for exposure to a pulsed traveling magnetic field on the human body, containing a clock source, and a pulse distributor connected via keys to the impact node, in which according to the invention the clock source is made in the form of a low-voltage rectifier and a clock generator connected to it , the output of which is the output of the clock source, and into which the high-voltage rectifier, timer and pulse counter are also introduced, while a pulse meter is connected between the output of the clock source and the input of the pulse distributor, the timer input is connected to the second output of the pulse counter, its output is connected to the pulse counter input of the pulse distributor, and the high-voltage rectifier is connected to the power input of the impact unit.

 The impact unit according to the invention is made in the form of a set of current coils.

 The device is also equipped with an operating mode indicator, the input of which is connected to the second timer output.

 The implementation of the source of clock pulses in the form of a low-voltage rectifier and a pulse shaper connected to it, as well as the presence of a counter, pulse distributor, timer and high-voltage rectifier, allow creating a running magnetic field at the exposure nodes, which provides a more effective effect on the human body, and also simplifies the circuit and reduce the cost of the device.

 The drawing shows a structural electrical diagram of a device for exposure to a pulsed traveling magnetic field on the human body.

 A device for applying a pulsed traveling magnetic field to a human body contains a clock source 1 made in the form of a low-voltage rectifier 2 and a clock driver 3 connected to it, a high-voltage rectifier 4, a timer 5 and a pulse distributor 6, a pulse counter 7, an impact unit 8 and keys 9, while the output of the pulse shaper 3 is connected to the input of the pulse counter 7, the outputs of the keys 9 are connected respectively to the inputs of the impact node 8, the pulse distributor 6 is turned on I wait for the output of the pulse counter 7 and the inputs of the keys 9, the input of the timer 5 is connected to the second output of the pulse counter 7, its output is to the input of the prohibition of counting the pulse distributor 6, and the high-voltage rectifier 4 is connected to the power input of the impact unit 8, which can be made in the form set of current coils. The device is also equipped with an indicator of the operating mode 10, the input of which is connected to the output of the timer 5.

 Impact node 8 is a set of current coils, keys 9 can be implemented, for example, on MOS field-effect transistors, low-voltage rectifier 2 can be made according to the half-period rectification circuit and be part of a clock shaper 3. Pulse distributor 6 can be made in the form of a binary decoder pulses, pulse shaper 3 - for example, in the form of an RC chain.

 A device for exposure to a pulsed magnetic field on the human body works as follows.

 The signals from the output of the pulse counter 7 are supplied to the corresponding inputs of the keys 9 through the pulse distributor 6. The keys 9, if there are impact pulses at their inputs, provide the voltage of the low-voltage rectifier 2 to the current coils of the impact unit 8, which leads to the excitation of the magnetic field by the current coils in accordance with the duration and timing of the alternation of exposure pulses. The duration of the exposure pulses is regulated by the pulse shaper 3. The program of alternating exposure pulses is set by the pulse distributor 6. These parameters are set in order to ensure the most favorable and effective treatment process based on the practical application of the device. Timer 5 sets the total duration of the operating mode. After this duration, the output signal of the timer 5 is fed to the stop input of the pulse distributor 6, thereby disabling the passage of pulses to the output of the pulse distributor 6 and the power supply of the current coils of the exposure unit 8. The number of keys 9 and, accordingly, the number of current coils of the exposure unit 8 is selected from the condition switching frequency optimal for influencing a biological object. At the same time, the signal from the output of the timer 5 is fed to the input of the operating mode indicator 10 and signals the end of the operating mode of the therapeutic effect of the pulsed magnetic field.

 For the practical implementation of this device, widespread integrated circuits and semiconductor devices can be used.

 The use of this device will significantly increase the effectiveness of the impact, since it makes it possible to select biotron parameters while evaluating the adaptive response to magnetic effects from a living object. In addition, the device is small in size and weight.
