Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention comprises a treatment bed at least partially formed as a vibration table, in which case an excitation device is configured to vibrate the vibration table so that the vibration table vibrates in three dimensions. The present invention relates to a device for vibration therapy, which acts on the body.

[Conventional technology]

The specific features of such a device are known from West German Utility Model No. 1864818. In this case, this known device is of course designed as a pine surge bed. Generating a predetermined vibration form thereby is not particularly important here.

A similar device is known from West German Patent No. 3008939. In the case of this device, vibrations in the plane of the bend and vibrations in the vertical direction perpendicular to it are generated based on the unbalanced body connected to the mass body that is eccentrically supported and rotationally driven. . In order to generate horizontal and vertical vibrations, two electric motors are used whose rotation speeds can be varied independently of each other. Depending on the adjusted frequency ratio, this results in completely different vibration forms, the so-called Lissajous form.
Ftguren) occurs. This form of vibration produces, in part, the desired therapeutic effect. However, this form of vibration, on the other hand, either does not help the treatment at all or is very uncomfortable for the patient. This form of vibration is very detrimental to the therapeutic outcome. This is because results can only be expected when the patient is completely relaxed. The relaxation of tension is
It is impossible to achieve this if you get angry due to discomfort. Another source of treatment failure is that the vibration of the diaphragm is unrestrained and it vibrates freely. The amplitude of the freely excited vibrations thereby depends on the resonant state of the entire system formed by the support plate and the patient resting on it. As a result, the resonance state not only differs from patient to patient depending on the patient's weight and weight distribution, but also, even for the same patient, on the particular way the patient lies on the support plate.

In view of the above, only a very close medical treatment observation coupled with a number of reverse controls will lead to the desired results. However, since the type of treatment in question is carried out by medical assistants, which places a greater burden on doctors, the number of sources of error must be reduced as much as possible.

[Purpose of the invention]

Starting from the above, the object underlying the present invention is to provide vibrations of the type mentioned at the outset, in such a way that they are easy to operate and very comfortable for the patient, and have an increased therapeutic efficacy compared to the devices described above. It is to form a treatment device.

(Structure of the invention and its effects) This problem is solved by driving the excitation device simultaneously and at a constant frequency ratio.This allows for a combination of frequencies for vibrations in various vibration directions. This direction of vibration is therapeutically ineffective or at least affects the health of the patient.

Furthermore, in the present invention, all the excitation devices are driven by one drive device. This solution is not only structurally simple and therefore reliably and cost-effective to implement, but also reliably achieves the required constant frequency ratio.

Furthermore, it is very advantageous if the vibration table is connected in a fixed manner to the excitation device. This makes it possible to obtain a constant amplitude in all directions, which can be preselected in any case, independent of the rotational speed of a single drive, which may be adjustable, and independent of resonance phenomena. . Furthermore, the constraint connection provides a very effective form of vibration, the so-called shock vibration. This type of vibration relaxes muscles by interfering with reflexes (suppressing the gamma loops in the reflex arcs of the vertebrae). Detonation is achieved simultaneously with hyperemia. Detonation is achieved in particular by avoiding vibrations that the patient finds unpleasant. In this case, individual adjustments can also be made by a medical assistant simply by changing the drive speed.

The idea of the invention can be realized in that the eccentric projection, which rotates in one plane parallel to the vibration table, is directly drivingly connected to the vibration table. Such a direct drive connection can be achieved if the eccentric lug follows the technology of an idler gearing, for example.
This can be achieved by being surrounded by a ball bearing connected to a vibration table or by the outer surface of the eccentric projection being designed as a needle roller hair ring. This needle roller bearing rolls on a ring connected to a vibrating table.

Preferably, the excitation device for generating vertical vibrations is formed by a rotating swash plate acting on the underside of the vibration table. In this case, it is desirable that the rotating swash plate is provided on the same drive shaft as the eccentric protrusion. This makes it possible to realize a structurally very simple simultaneous restraining connection for circular oscillations in the plane of the treatment bed or vibration table and for oscillations perpendicular to these oscillations.

It is very advantageous if, in the longitudinal direction of the treatment bed, a projectable leg rest is provided outside the vibration table for height adjustment.

In known devices, it is known to provide a cube under the patient's legs. Such a cube has certain predetermined dimensions and serves only as a support member. Therefore, in the case of the known device, in order to carry out the extension, the entire treatment bed is tilted downwards so that the patient's head is positioned below. This is extremely uncomfortable for many patients and thus interferes with the desired detonation.

According to the invention, the so-called Perl'
5chen) A combination of stretching and vibration therapy provides the optimal therapeutic effect. Pearl diene extension due to the preceding vibration treatment is reduced to a very short period of time, for example about 1 minute. This allows the patient to tolerate very efficient stretching.

As the vibration therapy device, the ones mentioned above are used, but fundamentally, significant improvement in pardien expansion can be achieved by using other types of vibration therapy devices as well.

According to a structurally very simple embodiment, the eccentric weight is driven in rotation by a drive such that the axis of rotation of the rotary bearing is arranged inclined at an angle α with respect to the plane of the vibration table. A rotating bearing is connected to the vibration table.

As a result, the vibration table performs vibrations divided into elliptical vibrations within the plane of the S& placement surface corresponding to the projection of the rotational motion of the eccentric weight, and vibrations perpendicular to the vibration table.

Furthermore, it is advantageous if the angle α is variable and adjustable. This allows the synthesis of three-dimensional vibrations of the shaking table to be changed. The component force perpendicular to the shaking table is
Compared to the amplitude of vibration in a plane, when the angle between the shaking table and the axis of rotation is very small, it is relatively large, and when the angle is very large, a flat vibration is more There is.

In order to further expand the application of such a device and to further increase the therapeutic efficacy in cases of pain in the cervical region, it is possible to provide for the headrest to be slidable in the longitudinal direction of the treatment bed and for the vibration table to be installed in this direction. It can be biased away from the surface by a tensile force. This allows a soft pulling force to be applied to the patient's head relative to the body. In this case, in combination with the vibrations of the shaking table, small strokes of intermittent tension are created between the head and the body. This tension is
In particular, it makes it possible to treat degenerative pain in the cervical vertebrae easily, uniformly, and extremely effectively, and to release the obstruction of the cervical vertebrae.

In another embodiment of the invention, the weight acts on the headrest via a guide device and a tension lobe or tension belt. By this means, a uniform tensile force is applied to the head even when the body is dynamically detonated and elongated due to the vibrations of the diaphragm. This increase in length is compensated for by sustaining the pulling force by the weight, which then moves slightly downward.

BRIEF DESCRIPTION OF THE DRAWINGS Other characteristics, advantages and details of the invention will become apparent from the following description of preferred embodiments based on the figures.

The apparatus shown in FIG. 1 includes a treatment bed 1 with a support structure 2 for a patient 3. The device shown in FIG. In this case, the mounting surface 2 is supported by a pedestal 4.

The mounting surface 2 includes a vibration table 5 and a leg rest device 6. This legrest is equipped with a device 7 for adjusting the height.

The rocking table 5 has an excitation device 9,1 driven by an electric motor 8.
0. One of the excitation devices can be vibrated circularly within the plane of the mounting surface 2, and the other can be vibrated perpendicularly to the plane superimposed on this vibration.

The treatment bend 1 includes a longitudinally extending cushion portion 11 provided on the side of the vibration table 5 and a head cushion portion 13 . This cushion part 11 has an inwardly inclined surface 12, and the head cushion part 13 has an inwardly inclined resting surface 14.

The treatment table 1 further includes a substrate 15 made of wood. This board is fixed via flanges 16 and bolts 17 to a metal frame 18 extending in the circumferential direction.

The vibration table 5 consists of a wooden board 19 and a cushion table 20.

The wooden base 19 rests on a metal frame 22 via four elastic shock absorbers 21. This buffer is commercially available under the name "+1 Silent-Block".

The protrusion 2 of this metal frame 22 protrudes outward and laterally.
3 supports an elastic shock absorber 24.

This damper forms a suspension on the free leg 25 of the frame 18.

The frame 18 itself is mounted on vertical supports 26 as part of the pedestal 4.
It is connected to the lower frame 27 via.

The lower frame 27 is provided with leg protrusions 28 that project laterally. An elastic shock absorber 29 is fixed to this leg protrusion. The other end of this buffer is fixed to a protruding leg 30 of a profile frame 32 on a floor 31.

As can be seen from the above, the vibration table 5 is equipped with an elastic shock absorber 21.
It is supported on the floor 31 via three planes 24 and 28. In this case, the buffer 21 is biased in compression and the buffer blocks 24, 29 are biased in tension.

Due to the series arrangement of the damping suspensions, the therapeutic shock vibrations generated by the device of the invention are not transmitted to the floor. Damage to the floor or building is therefore reliably prevented.

In FIG. 6 the exciter device 9.10 is shown in detail. A shaft 36 supported by a ball bearing 34 of a column 35 of the pedestal 4 is driven by a belt drive device 33 via an electric motor 8 (see FIG. 1) fixed to the pedestal 4. Upper end 37 of shaft 36
A cylindrical eccentric protrusion 38 is eccentrically fixed in the following manner.

That is, the central longitudinal axis 39 of this protrusion is fixed so as to be offset from the central longitudinal axis 40 of the shaft 36 by an amount IA.

A plurality of support pins 41 are provided on the lower surface of the wooden board 19 of the vibration table 5.
is fixed. This support pin carries a ball bearing 42 , and the outer ring 43 of this ball bearing is in contact with the eccentric pin 38 , so that the rotational movement of the shaft 36 is transmitted through the eccentric projection 38 and corresponds to the eccentricity of the eccentric projection 38 . Shaking table 5 with amplitude A
is converted into a circular vibration motion of the shaking table in the plane of . That is, the eccentric protrusion 38 forms the first exciter 9 together with the ball bearing 42 and the pin 41 .

A rotating swash plate 44 is fixed to the upper surface of the eccentric protrusion 38. The upper surface of this rotating swash plate is the longitudinal axis 39 of the eccentric protrusion 38.
or inclined with respect to a line perpendicular to axis 40.

This upper surface is in contact with the ball 45. The ball is supported on a wooden board 19 of the vibration table 5 at the center Z of the vibration table 5. Corresponding to the inclination of the rotary swash plate 40, the vibration movement is transmitted to the vibration table perpendicularly to the plane of the vibration table 5 via the balls 45 and is superimposed in this plane with a circular vibration, which also causes the rotation tilt. The plates 44 are superimposed with an amplitude B corresponding to the maximum difference in height. The rotating swash plate 44 together with the balls 45 forms the second exciter 10 .

FIG. 8 is a top view of the treatment bed 1.

As can be seen from this figure, a projectable leg rest device 6 is provided below the vibration table 5 in the area of the legs. This leg rest device is shown in detail in FIG. 1 or in FIGS. 9 and 10.

The calf rest device 6 includes a leg cushion 46.

This leg cushion is attached to the spindle 4 via the holding member 47.
It is supported on the top surface of 8. This spindle 48 is the ninth
As shown in the figure, the supports 4 of the pedestal 4 are

An electric motor 51 is attached to the . This electric motor is connected to the nut 5 via a gear system 52 and a chain drive system 53.
Drive 4. This nut is axially fixedly mounted on the support 49, so that by rotating the nut 54, through which the spindle 48 is guided, the height of the spindle 48 and thus the cushion 46 can be adjusted. height adjustment is performed. In order to provide a certain lateral guidance, the holding element 48 includes guide projections 55 . This guide projection is supported by a longitudinal ball bearing 56.

As can be seen from FIG. 10, the spindle 48 is inclined with respect to the mounting surface 2 so as to be separated from the center Z of the vibration table 5 by about 4 degrees. As a result, a light movement towards the leg end is achieved when performing the height adjustment operation via the electric motor 51. That is, a very body-specific adjustment is achieved.

FIG. 12 shows how the electric motor 8a in the embodiment described above is connected to the molded part 62 by means of its flange 60 and the indicated bolt 61. The shaped part itself is bolted to the temporary 19 of the vibration table 5 via the indicated bolt 63.

The molded member 62 is provided with a recess 63'. In these four parts, an eccentric weight 64 in the form of an eccentric disc is located on the shaft 6.
5. In a simple case, this shaft is the driven shaft of the geared electric motor 8a. The axis of rotation 6 of the rotation bearing for the eccentric weight 64, formed by the axis 65
5' extends at an angle α to the plane of the vibration table 5.

In this example, this angle is approximately 45°.

According to the embodiment shown in detail in the figures, the shaped part is designed in such a way that the eccentric weight 64 can be swung over an angular range β of, for example, 5 to 85° with respect to the plane of the vibration table 5.

The vibration applied to the vibration table 5 in the direction of the arrow 66 is caused by a component force (component 67) perpendicular to the plane of the vibration table 5 and a component force perpendicular to the plane of the vibration table 5.
It is divided into two component forces 68 perpendicular to each other in the plane of .

Of these force components 68, only one force component is shown in FIG. 3 for clarity. Thereby, three-dimensional vibrations are excited in the vibration table 5 by simple means and using only one drive device.

In the area of the pedestal 5 of the treatment bed 1, below the head area, an equipment storage box 6 is provided.

The patient 70 shown in FIG. 13 has almost his torso resting on the vibration table 20. The patient's head 80 rests on a headrest 90.

Headrest 90 includes two substantially vertical supports 100. A large number of slits 120 extending laterally are formed in the upper end 110 of this support member 100. A clip 130, schematically shown in FIG. 13, is engaged with this slit 120. This clip is fixed to both lateral ends of the belt structure. The belt structure 140 is in the form of a hammock and is loaded by the head 80 of the patient 70! An I2 position recess 150 is formed.

In the area of the head recess 150, a rope 160 acts on the belt structure 140. This mouth is guided through a guide pulley 170 as follows. That is,
It is guided first longitudinally rearward and then vertically downwards. In this case, a weight 190 is suspended from the end of the rope.

The guide pulley 170 is supported by a support arm 200, which is fixed to the back of the rack 50 or the equipment storage box 60.

The head stand 90 is supported slidably in the longitudinal direction. For this purpose, the lower end 210 of the support 100 is connected to the bearing box 220@
We are prepared. This bearing housing includes two segmented ball noches that are parallel to each other and extend horizontally.
