Definitions

  • the invention relates to the satisfaction of human life needs, to devices for stimulating reflex points on the surface of the body and relates in particular to electromagnetic vibrators.
  • a large number of devices for stimulating reflex points of the human body are known.
  • the closest to this are vibrators with an electromagnetic and electrodynamic system, depending on the mode of operation and the demands placed on the vibrators.
  • a vibrator (see RC Bice. Electromechanical Transducer for Vibratoactile Stimulation "The Review of Scientific Instruments", V. 32, No. 7, 1961, 856-857) is known which contains a body in which an excitation coil and a Membrane with a weight attached to it.
  • the body in which the magnetic system is located becomes an oscillating member.
  • the amplitude of mechanical vibrations fanned by a bice vibrator is frequency-dependent and has a maximum of 145 Hz, which is inadequate for vibro-stimulation of mechanoreceptors in humans.
  • the vibrator has a large diameter of 23 mm, a large height of 33 mm and a large weight of 47.5 g, which also makes it difficult to attach and this in a number of cases, for example in the sleeve of a prosthesis makes impossible.
  • the amplitude-frequency characteristic of the vibrator has a linear profile in a range from 0 to 50 Hz, with the frequency increase above 50 Hz the vibration amplitude decreases and is close to 0 in a range of 100 Hz.
  • the vibrator is rectangular with dimensions of 32x20 mm and a weight of 70 g, which is insufficient for its use in the devices for stimulating reflex points.
  • the vibrators described are not designed for the transmission of impulse signals, do not have a sufficient vibration amplitude and are powerful.
  • the vibrator has a diameter of 29 mm and a height of 17.2 mm and a weight of 50 g.
  • the spring in the electromagnetic vibrator limits the frequency characteristic of the vibrator to a range up to 50 Hz and reduces its reliability during continuous operation. The dimensions of this electromagnetic vibrator limit the possibility of its use for the solution of practical tasks.
  • the invention has for its object to provide an electromagnetic vibrator, the construction of which ensures a maximum force effect on the mechanoreceptors in a range from 0 to 250 Hz with an oscillation amplitude of 1 mm and the minimum values of weight and dimensions of the vibrator and which reliably Is continuous operation.
  • the object is achieved in that in the electromagnetic vibrator, the body of which includes a clapper with a cover and an excitation coil in sicn, which generates an alternating magnetic field, under the action of which the clapper moves back and forth along the geometric axis of the excitation coil executes, the clapper according to the invention is exposed in the body and contains a permanent magnet, the surface of the excitation coil facing aer interaction of the magnetic field of the excitation coil with that of the permanent magnet in a 0.6 to 0.7 the height of the excitation coil the same distance from the excitation coil flange .
  • a second permanent magnet in the cover of the body of the electromagnetic vibrator, which stent interacts with the permanent magnet of the clapper and builds up a magnetic field which is directed along the axis of the clapper against the magnetic field as the permanent magnet of the clapper.
  • the clapper with the permanent magnet that moves freely inside the excitation coil and is arranged in this way is that the surface facing the excitation coil is at a minimum distance of 0.6 to 0.7 the height of the excitation coil from the coil flange, generates a large impact force and exerts a corresponding force effect on the mechanoreceptors in the setpoint range.
  • this force increases with the help of a so-called "magnetic spring” + which is realized by arranging a fixed permanent magnet in the cover of the body, whose field along the axis of the clapper is opposite to the magnetic field of the permanent magnet of the clapper.
  • the interaction of the magnets mentioned completely mimics that of a spiral spring when the electromagnetic vibrator is working and takes over its function, thereby extending the duration of trouble-free operation of the vibrator.
  • the electromagnetic vibrator shown in the drawing contains a body 1 in which a clapper 2 is exposed and an excitation coil 3 is housed.
  • a permanent magnet 4 is arranged in such a way that its surface facing the excitation coil 3 is at a minimum distance from a flange 5 of the excitation coil 3 that is the same as 0.6 to 0.7 the height of the excitation coil 3.
  • a cover 6 is fastened to the body 1, in which a second permanent magnet 7 is arranged.
  • the leads of the excitation coil 3 are not indicated in the drawing.
  • the electromagnetic vibrator works as follows.
  • the excitation coil 3 When the electromagnetic vibrator is connected to an AC circuit, the excitation coil 3 generates a alternating magnetic field, under the action of the clapper 2 executes a reciprocating movement along the geometric axis of the excitation coil 3.
  • the clapper 2 When a current flows through the excitation coil 3, the clapper 2, when the directions of the magnetic fluxes of the excitation coil 3 and the permanent magnet 4 of the clapper 3 coincide, are drawn into the excitation coil 3 with a force which is a sum of their flux gradients minus a flux gradient of a fixed permanent magnet 7 is proportional, and the permanent magnet 4 of the clapper 2 remains at the same distance from the coil flange 5 at 0.6 to 0.7 the height of the excitation coil 3.
  • the clapper 2 is displaced in the direction of the object to be excited with a force which is proportional to a sum of the flow gradients of the permanent magnet 4 of the clapper 2, a fixed permanent magnet 7 and the excitation coil 3.
  • the experimentally determined values correspond to the position of the permanent magnet 4 at a distance of 0.6 to 0.7 the height of the excitation coil 3 equal distance from the coil flange 5 of the greatest strength of the bobbin 2.
  • the impact strength decreases, which is due to a reduction in the overall magnetic field gradient, while at a distance of less than 0.6 the invention cannot be implemented with the selected dimensions.
  • the feststenenae permanent magnet 7 thus performs, together with the permanent magnet 4 of the clapper 2, the function of a magnetic spring, which is pressed together when the clapper 2 is pulled into the excitation coil 3 and displaces the clapper 2 from the excitation coil 3 when the current direction changes in the latter.
  • the electromagnetic vibrator according to the invention develops a large impact strength based on its volume (approx. 30 g / cm 3 ), has a diameter of 22 mm with a height of 10 mm and a weight of 12 g, and the vibration amplitude of the Clapper 2 is in a required frequency range from 0 to 250 Hz guaranteed.
  • the electromagnetic vibrator according to the invention contains no spring, no elastic intermediate layers, which enables its occupational safety in continuous operation.
  • the electromagnetic vibrator is used for the prevention and rehabilitation of a disorder of motor functions of the lower extremities and a vestibular disorder in humans by excitation of the mechanoreceptors of skin covers in the support zones of the feet according to the time and force parameters of the natural locomotive act of humans.
  • the electromagnetic vibrator can be used to transmit information about the parameters of a prosthesis, primarily about the holding force, and for vibrotesting the skin of the human organs.
