    The invention relates to a device for magnetic stimulation of regions of a human or animal body, comprising at least one magnetic coil which is connected to a stimulator having a power unit for generating electrical impulses to be applied to the at least one magnetic coil, so that in the at least one magnetic coil generated magnetic field in the body region is inducible.
    In contrast to functional electrostimulation (FES), in which a muscle or nerve is electrically stimulated via contacting electrodes to perform a muscle contraction or to influence other nerve functions in order to support or replace certain physiological processes, in functional magnetic stimulation (FMS) a Nervenakti-vation, for example, can lead to muscle contraction, triggered by appropriate magnetic fields without contact.
    Functional magnetic stimulation has the significant advantage over functional electrostimulation with electrodes located on the surface of the skin that pain sensors located in the skin are activated much less and the application with comparable neuromuscular activation is perceived as much more pleasant. This is due to the fact that the pain sensors are in comparison to deeper tissue portions of high-resistance tissue layers. The current flow during electrical stimulation therefore causes relatively high electric field strengths, especially in the area of pain sensor technology, while the effect-relevant induced eddy currents are much more pronounced in the case of magnetic stimulation in the low-impedance underlying tissue than in near-surface, high-resistance tissue.
    Furthermore, in functional magnetic stimulation, the expense and the risk due to the elimination of the often necessary implantation of nerve or muscle electrodes in functional electrostimulation is substantially lower and the acceptance higher. In contrast, targeted stimulation of certain nerves or muscles via the magnetic field is more difficult than with direct electrical stimulation using skin electrodes or implanted electrodes. In particular, it is very difficult to achieve certain points, so-called motor stimulation points or motor points with the magnetic field and to achieve, for example, the contraction of the desired muscles in the Sti simulation of deeper-lying regions.
    An example of a device for magnetic stimulation is described in WO 2009/126117 A1. With the help of a magnetic coil, a magnetic field is induced into deeper tissue layers, resulting in a depolarization of neuronal cells, which leads to muscle contractions of certain muscles in certain body regions.
    Another method and a device for neuromagnetic stimulation has become known from EP 0 617 982 A1, in which a focused ultrasound beam is superimposed on the magnetic field, which should allow a more precise spatial stimulation.
    A method and a device for pelvic floor training using magnetic stimulation has become known, for example, from DE 10 2012 012 149 A1. In addition to magnetic stimulation, the tissue is still supplied with oxygen and / or ozone to further support the training and development of the musculature.
    The object of the present invention is to provide an above-mentioned device for magnetic stimulation, by which an optimal direction of the magnetic field to the respective motor stimulation points and thus optimal stimulation can be achieved. At the same time, the invention is intended to concentrate the magnetic field effect in such a way that it acts as selectively as possible on the tissue area to be stimulated, but adjacent areas in which e.g. Implants lie, largely spared. Disadvantages of known stimulation devices should be prevented or at least reduced.
    The object of the invention is achieved in that the at least one magnetic coil is adjustable via an adjustment relative to the body region to be stimulated and designed so that the body region to be stimulated within the induced magnetic field can be arranged and adjustably connected to each other via the adjustment. Due to the adjustable arrangement of the at least one magnetic coil relative to the body region to be stimulated, an optimal arrangement of the at least one magnetic coil with respect to the body region to be stimulated can be achieved and thus optimal stimulation of the respective motoric stimulation points or motor points can be effected. The adjusting device is adapted accordingly to the body region to be stimulated.
    According to a first embodiment of the stimulation device, at least two magnetic coils designed as air coils are provided, which can be arranged on both sides of the body region to be stimulated and are adjustably connected to each other via the adjustment device. The at least two magnetic coils designed as air coils thus include the area to be stimulated and cause a corresponding concentration of the magnetic field in the deeper body regions where the motor stimulation points or motor points to be stimulated are arranged. The adjustable arrangement of the air coils, the body region to be simulated, for example, a limb, optimally disposed between the magnetic coils and a highly concentrated magnetic field in this body region and thus optimal stimulation can be achieved.
    In the case of the body region to be stimulated on both sides, the adjusting device can be formed from at least two air coils made of magnetically non-conductive or magnetically insulating material, in particular plastic. This prevents a magnetic short circuit of the magnetic field lines emanating from the at least two air coils. In addition, plastic is inexpensive to produce and has a low weight.
    According to a second embodiment, the at least one magnetic coil is arranged on a magnetic yoke, wherein the poles of the magnetic yoke can be arranged on both sides of the body region to be stimulated and adjustably connected to one another via the adjusting device. In the case of this embodiment variant, the body region to be stimulated is arranged between the poles of the magnetic yoke and an adaptation to the size of the body region to be stimulated is achieved by corresponding adjustment of the poles of the magnetic yoke. Also in this case, a targeted concentration of the stimulating magnetic field in the deeper body regions and thus optimal stimulation of the respective motor points can be achieved.
    If the adjusting device is formed of magnetically conductive material, such as iron, it may form part of the magnetic circuit or magnetic yoke.
    In the simplest case, a displaceable arrangement of the two magnetic coils or poles of the magnetic yoke is sufficient to be able to arrange the body region to be stimulated therebetween and to be able to adapt the stimulation device to the size of the area to be stimulated. For more complicated adaptations to the shape of the respective body region, the combination of a swivel joint with a sliding joint is advantageous.
    If drives for adjusting the rotary joint and / or the sliding joint are provided, an automatic adjustment of the position of the magnetic coils or poles of the magnetic yoke can take place. In the simplest case, however, the adjusting device can also be made passive and, for example, contain a spring element against which an adjustment can take place. In this way, for example, a breath-synchronous movement of the stimulation device can take place during a stimulation in the region of the thorax. In the case of a motorized adjusting device, such a movement could also take place synchronously with the respiration by means of corresponding sensors.
    The actuators may be connected to pressure sensors to avoid unduly high pressure on the body region to be stimulated or to detect the presence of the magnetic coil or magnetic pole on the body surface. As pressure sensors a variety of optical or mechanical sensors come into question.
    In order to be able to make the treatment more comfortable for the patient, a couch or a seat can be provided, wherein at least one magnetic coil is arranged below the couch or the seat, if necessary in a corresponding adaptation. In this way, also lying or even sleeping patients or intensive care patients can be stimulated. For example, stimulation of the diaphragm during intensive care may be performed, e.g. to prepare the patient for weaning from the respirator.
    Even more targeted stimulation can be achieved by providing elements for concentrating the magnetic field. Various elements for concentrating the magnetic field, in particular concentration coils or permanent magnets, are used.
    The invention will be explained in more detail with reference to the accompanying drawings which illustrate embodiments of the invention. Show:
    1 shows a schematic diagram of the functional magnetic stimulation of deeper body regions according to the invention;
    FIG. 2 shows a block diagram of a variant embodiment of the magnetic stimulation device according to the invention with two magnetic coils embodied as air coils; FIG.
    3 shows a block diagram of a further embodiment variant of the magnetic stimulation device according to the invention with a magnetic coil and a magnet yoke;
    4 shows a schematic diagram of a couch with a magnetic stimulation device according to the invention; and FIG. 5 shows a detailed view of a magnetic stimulation device with elements for concentration of the magnetic field.
    Fig. 1 shows a schematic diagram of the inventive functional magnetic stimulation deeper body regions. The device 1 for the magnetic stimulation of regions R of a human or animal body comprises at least one magnetic coil 2, which is connected via corresponding connection lines 14 to a stimulator 3, which has a power section 4. The power section 4 generates the electrical pulses or signals which are applied to the at least one magnetic coil 2. Such pulses are ideally rectangular in shape, but for certain applications may be other shapes such as e.g. Triangular shape or sinusoidal form, can be generated by which alternating fields in the magnetic coil 2. By means of the electrical impulses, a magnetic field H is generated in the at least one magnetic coil 2, which is induced in the body region R and causes effects at desired points, so-called motor points, which can lead to muscle contractions of the desired body region R, for example. For example, such functional magnetic stimulation of the diaphragm can be used to ventilate a patient.
    In order to achieve a more concentrated arrangement of the magnetic field H in the region R to be stimulated, the at least one magnetic coil 2 is connected to an adjusting device 5 in order to be able to adjust the at least one magnetic coil 2 with respect to the body region R to be stimulated. Thus, an optimal adaptation of the magnetic field H with respect to the region to be stimulated R can be made.
    2 shows a block diagram of a variant embodiment of the magnetic stimulation device 1 according to the invention with two magnet coils 2, 2 'designed as air coils. The two magnetic coils 2, 2 'are connected to each other via the adjusting device 5 and arranged so that the body region R to be stimulated between the magnetic coils 2, 2' can be arranged. By adjusting 5, an optimal adjustment of the position of the magnetic coils 2, 2 'with respect to the body region R to be stimulated can be achieved. In the case of the construction with two opposing magnet coils 2, 2 ', the adjusting device 5 is preferably formed from magnetically non-conductive or magnetically insulating material, for example plastic, in order not to cause a magnetic short circuit of the field lines emanating from the magnet coils 2, 2'. The adjusting device 5 may include a pivot joint 9 and / or a sliding joint 10. By adjusting at least one magnetic coil 2, 2 ', the magnetic field H can also be better concentrated in the region R to be stimulated, since the magnetic coils 2, 2' can be brought closer to this body region R. For example, the upper magnetic coil 2 in the case of stimulation of the upper body and something in the skin and fat tissue of the respective body region R are pressed. When stimulating moving body parts, for example the thorax, it is also possible to track the at least one magnetic coil 2, 2 'synchronously with the respiration. In this case, a purely passive adjustment 5 in the manner of a spring-biased pliers are used, in which the at least one magnetic coil 2, 2 'is moved against the spring force. On the other hand, an automated and driven adjusting device 5 is conceivable in which the rotary joint 9 and / or sliding joint 10 is connected to a drive and the movement is controlled synchronously to the respiration (see Fig. 4).
    In Fig. 3 is a block diagram of another embodiment of the magnetic stimulation device 1 according to the invention with a magnetic coil 2 and a magnetic yoke 6 is shown. In this case, the poles 7, 8 of the magnetic yoke 6 are adjustably connected to each other via the adjusting device 5 and include the body region R to be stimulated. To ensure a closed magnetic circuit, the components of the adjusting device 5 of magnetically conductive material, such as iron, are formed in this case. Also in the case of this embodiment, the adjusting device 5 may consist of a rotary joint 9 and / or a sliding joint 10.
    FIG. 4 shows a schematic diagram of a couch 13 with a magnetic stimulation device 1 according to the invention. The magnetic stimulation device 1 is formed from at least one magnetic coil 2 and a magnetic yoke 6 and designed so that the poles 7, 8 of the magnetic yoke 6 are arranged substantially opposite, so that the body region R to be stimulated between the poles 7, 8 of the magnetic yoke 6 is can be ordered. The magnetic coil 2 or a magnetic pole 7 is arranged below the couch 13 or in a recess therein. The patient or the body region R to be stimulated rests on the couch 13, whereby stimulation is also possible in the lying state or in deep sleep in intensive care patients. The adjusting device 5 is similar to the variant of FIG. 3 constructed, wherein the pivot joint 9 and the sliding joint 10 is connected to a respective drive 11 to allow automatic adjustment. For this purpose, the drives 11 are connected to a corresponding drive control 17. In order to avoid unduly high pressure exerted on the body region R to be stimulated, pressure sensors 12 can be arranged on the poles 7, 8 of the magnetic yoke 6, which can be connected to the drive control 17.
    Finally, FIG. 5 shows a detailed view of a magnetic stimulation device 1 with elements for concentration of the magnetic field H, which may be formed, for example, by suitably arranged permanent magnets 16.
