Abstract

The invention relates to a bed (1), comprising a support (10) that can be automatically, continuously moved back and forth between different positions so that the vertebral column and other joints e.g., of the hips, knees or legs can be moved and exercised specifically.

Description

The invention relates to a reclining device with a Body or mattress pad as lying surface with several moving parts showing the shape of the spinal curvature can adjust. Such a device is e.g. in the US-A-5,235,710. In particular, will but also to the lumbar spine but also to the other Areas of the spine thought. In such a Lying device is, for example, around a slatted frame for a bed, a couch, a Mattress, a waterbed, a device for spine therapy or around an armchair leading to the couch can be transformed.

In many bed frames is the headboard, the back part and / or the foot part adjustable to a more comfortable To be able to take attitude.

So far it was assumed that a hollow cross (Lordosis) is positive as it is the natural spinal curvature supported. For chairs and seats Therefore one usually finds a loincloth. From the For the same reasons, the recommendations are found e.g. one Push cushions under your back. A shallow or round back (kyphosis), according to many Recommendations are avoided, as it leads to a high load of the intervertebral disc come. It was assumed, that this higher pressure at the same time wedge-shaped opening angle the intervertebral disc nucleus (Nucleus Pulposus) push back and thus problems causing. These findings were above all on intradiscal in vivo studies, the performed in the sixties. These Measurements at that time showed that when sitting the load 40% higher than standing up. As you stand up lumbar lordosis, it should to be taken while sitting, to reduce the burden of Reduce spine in this way. Previous Measurements in the seat showed that here the load can be reduced if the lordosis supports would.

The inventor, however, has a direct in vivo Intervertebral pressure measurement found that the above Findings can not be upheld. Sitting is not according to his new findings more burdensome than standing, whereby previously published Results based on indirect measurement methods be confirmed. Sitting can be the pressure in the intervertebral disc in the previously banned casual Sitting posture, i. when sitting with a round back, even be reduced to half. (Wilke HJ, Neef P, Caimi M, Hoogland T, Claes LE New in vivo measurements in the intervertebral disc in daily life. Spine 1999 Apr 15; 24 (8): 755-62). These disapproved casual but comfortable posture with lightweight Round back creates a significantly lower load the disc, as the previously recommended upright Seating position with hollow cross, i. with lumbar lordosis. These contradictions to the earlier results can be attributed to the different measuring techniques become.

Studies carried out by the inventor have shown that that a changing pressure load in the The aim of the intervertebral disc is because the intervertebral disc then fed thanks to their "sponge principle" (Wilke H-J, Claes LE (ed.) (1998) The Traumatic and degenerative disc Springer Verlag Heidelberg ISBN 3-540-65108-X). In knowledge of this Conditions, the invention is based on the object a reclining device of the type mentioned to create, with which it is possible, the spine and other joints of a person alternately to load and relieve.

This task is followed by a reclining device Claim 1 solved. Advantageous developments of Liegevorrichtung invention are in the respective given dependent claims.

The above object is in a reclining device of according to the invention, that the lying frame, for example, between a lordosis and a kyphosis position automatically back and forth adjustable. It should on a uniform lumbar support of the respective Respected people are respected.

According to the invention, the reclining device is therefore at least in sections in height and / or inclination adjustable, with the support of the reclining device repetitive automatically in a predetermined manner is adjustable by the drive. this means for example, that the edition, if it is is a slatted base, relative to single slats as sections or with respect to several with each other connected slats as a section so adjustable is that these sections from the lying surface can be raised or tilted to this. Especially in the case that is on this slatted frame a mattress is equal to the mattress this increase or inclination, so that a uniform Protrusion of the mattress surface at the Place takes place at the bar or the lath section was lifted from the support profile.

According to the invention, this profiling is now in itself repetitive way automatically by a drive adjusted so that the back of the mattress Lying constantly in a repetitive manner between different positions, for example, between Lordosis and kyphosis position of the human Spinal regions such as lumbar spine, thoracic spine and cervical spine is moved back and forth. The same is true, for example, for the legs and hips or knee or for the chest, shoulder, and neck Header possible. By such oscillating or periodic movement is therefore the Spine of the person lying on the mattress bent in different directions, so that a optimal alternating loading and unloading of the different ones Spinal structures (ligaments, bones, cartilage and the like) and care of the intervertebral discs is possible while the person is lying on the couch relaxed or, for example, asleep.

The lying device according to the invention allows a continuous movement of the cervical, thoracic and lumbar spine, the hip and knee joints. These Joints may be in different positions (e.g. Lying position, relaxation position and upright sitting position) each separately or in different combinations be moved continuously. The movements in each joint can vary depending on the position with different amplitudes and different frequencies to be controlled.

In the prior art, the spinal curvature becomes not targeted to the anatomical and biomechanical Given conditions of an individual. In the present invention is intended by the reclining device the contour of the back and thus the shape the spine can be targeted. The spine should, for example, both a Lordosis and kyphosis.

Before using such a reclining device Values regarding anatomical and / or biomechanical Conditions of a human, e.g. about the Flexibility of the spine of the lying on it People also determined in sections, for example for the cervical or lumbar spine, for example, the strongest possible Deflections in kyphosis or lordosis position respectively be determined. From these values and if necessary Information about health requirements to humans, e.g. special training programs for certain diseases or diseases conditional restrictions on mobility individual joints or spinal sections then control values can be obtained to the to be controlled according to the invention couchette device so that the person lying on it individually of its anatomical Conditions such as his spine flexibility and the health requirements adapted to be moved back and forth.

The movement programs can be realtiv to a Reference position, e.g. the most comfortable for a man Lying position (relative movement program, or independent of such a reference position absolute movement program determined and controlled become.

The reclining device contains a control for this purpose for the drive, which can be adjusted accordingly or is programmable. She receives her data via a Data collection device, the data from outside which is the original data from the Measurement on the person or already revised Control data can act.

A decisive advantage of the present invention is that the reclining device can be adjusted completely individually to the individual person, wherein the programming or setting can also be changed over time, when changing the flexibility of the spine in the person. Consequently, the lying device according to the invention thus adapts to the particular person lying on it during its entire life. This may also be of interest in the event that such a reclining device is used for example in hospitals, where in each case then the reclining device can be adjusted to the respective patient.
Common wisdom is that in flexion, the disc bulges to the rear. In vivo studies by the inventor have shown that this doctrine is wrong. The opposite is the case. In kyphosis, ie in the hunchback, compressive forces act on the anterior annulus (anterior annulus). These compression forces cause bulging forward. At the same time there is a tensile stress in the posterior ring (posterior annulus). This causes a stretching of the collagen fibers and thus a less bulging. This can be impressively demonstrated with the help of a contrast medium radiograph of the spinal canal (myelography). Although it has been shown experimentally that the nucleus is displaced to the rear during flexion, this displacement is much lower than previously reported. At the same time, the posterior portion of the outer disc ring tends to be slightly inward. A slight change is observed when the disc nucleus is missing due to herniated disc or due to surgery. The outer fiber ring, however, behaves similarly. Patients with a narrowing of the spinal canal (spinal canal stenosis or similar), even open these channels in kyphosis and take the pressure off the nerve structures. Even the circulation in the space surrounding the spinal cord (epidural space) is improved.

The diffusion of solutes may be in the lordosis position, easier in the front half of the intervertebral disc as done in the back half. This Imbalance is reversed in the inflected posture. In the kyphosis position, the diffusion is total stronger, even in the posterior part of the disc much stronger than upright posture.

In a posterior bow, i. with strong lordosis, it comes to the increased surface pressure on the vertebral joints. The compression forces also increase the posterior portion of the disc pulley ring and between the spinous processes. A constant hyperlordosis acts as an initial stimulus to osteoarthritis in the small vertebral joints. The constant hyperlordosis leads to the painful picture of a Bastrup syndrome. A fixed Lordosenstellung leads to the Duration to a shortened musculature.

For the reasons mentioned above, it can be positive if the one user while lying is more likely to have a lordosis or can cease kyphosis.

Static or compulsory postures are in most Cases not useful or even harmful. For this Reason also arise manifold problems alone due to a static posture while sitting or even while sleeping, etc. This becomes clear to everyone, if he stays for a long time even in a comfortable angle of the back, e.g. reading a book. The muscles tired, certain parts of the band are stretched on one side, certain parts of the disc are compressed or loaded on train. The liquid of the Cartilage in the articular facets is e.g. extruded and a diffusion of nutrients no longer guaranteed. These structures all need one changing load. That's why the back should be in these static positions are moved.

This obvious disadvantage sets one up Problem in people over a long time up have to lie to the back.

From the above advantages and disadvantages follows, that there is no optimal spinal curvature, when taken statically. When lying down will therefore constantly changing position to the structures different and varying demands. That also means that from a kyphosis position is not to be discouraged, but that this taken in dynamic change with the Lordosenstellung shall be. Be the tissues of the musculoskeletal system of the lie user by movement and Exercise trained, so they get the mechanical Stimuli that they need to maintain the structure. An additional burden on bone and Muscles a mass increase and improves their biomechanical properties. In addition, the react Cells of these tissues with increased cell proliferation and with increased metabolic activity (Neidlinger-Wilke C., Wilke H-J, Claes L. Cyclic Stretching of Human Osteoblasts Effects Proliferation and Metabolism: a New Experimental Method and its Application Journal of Orthopedic Research, No. 12 pp. 70-78, 1994).

The diet of cartilage and intervertebral discs takes place by diffusion, by such a changing load is strongly favored. At high load The fluid is made from the appropriate tissues squeezed out, using spent metabolites get picked up. After that, the tissues may be in the Relieved condition with fluid and nutrients like a sponge again soak up. Missing said dynamic alternating stress, so become cartilage and intervertebral discs are no longer sufficiently nourished and react with a degeneration. It follows that the intervertebral disc of a person while lying alternately loaded and should be moved in a variety of ways. this will Involuntarily practiced while sleeping by one is constantly turning. But that is also by the invention dynamic reclining device possible, in which the back part is preferably continuous dynamically oscillating between a lordosis position and a Kyphosenstellung back and forth adjustable is and thus for a long time the supine position can take. This applies in appropriate Way of practicing legs, knees and hips, which should be moved continuously changing.

It has proven to be advantageous in the lying device according to the invention, when the amplitude and / or the frequency of the dynamic, oscillating adjustment between lordosis and kyphosis position is adjustable. According to the amplitude, the area between the two extreme positions can be, for example, up to 120 ° of the lower cover plate of the lumbar vertebra L1 and the upper cover plate of the sacrum S1. The frequency of the dynamic adjustment between the Lordosen- and the kyphosis position, for example, in the range between the order of 0, 5 sec -1 to about 1 h -1 amount.

In the lying device according to the invention, the dynamic oscillating adjustment between the Lordosenstellung and the Kyphosenstellung by the Bed users active or automatically by means of a drive device respectively.

According to the invention, the reclining device with a Drive device to provide, with their help e.g. the back part continuously oscillating dynamically between a lordosis and kyphosis position is moved back and forth. In this drive device it can be, for example, an electric motor, to a hydraulic motor or the like. act.

This invention will cause back pain be reduced. You can cant in the same one stand erect longer, e.g. to read because the structures are loaded and relieved alternately what will be the bed user without this movement forces the change of movement. The movement can Furthermore, the atrophy of structures in Bettlägrigen to reduce.

It is preferred if in the reclining device according to the invention the back not only continuously dynamic between a lordosis and a kyphosis position is adjustable back and forth, but if the back part also adjustable in its inclination is. Furthermore, it may be preferred if in the Couch according to the invention, the foot also moved continuously or discontinuously becomes. By such training of the latter Art also become relevant structures of others Joints of the bed user such as cartilage, bones, ligaments and muscles e.g. at the hips and knees while lying down and relieves and thus trained. This leads to an improved diet of these Structures and to improved breathing, blood circulation and digestion and thus a better one Well-being.

FIG. 1 shows schematically in a side view a Formation of a reclining device 1 with a leg part 2, 3 (here for example two-part) and a multipart (here exemplarily four-part) back part 4 to 7. The leg part 2 and the head part 7 are as well as the other areas 3 to 6 in their inclination adjustable. This is through the arcuate Arrows 8 and 9 indicated.

In Figure 1, the reclining device 10 takes a position a, in which the back part inclined downwards and the back part allows a kyphosis.

The same or similar elements are shown in FIG. 2 as in FIG the following figures with the same reference numerals as designated in Figure 1, so that it is unnecessary, this To describe elements in detail again each time.

In the reclining device 1, the back part of the segments 4 to 7 continuously oscillating dynamically between the Lordosestellung clarified in Figure 2 and the kyphosis position indicated in FIG be adjustable back and forth (see arrow 9). This adjustment can be active by the user or passively and automatically by an appropriate Drive device (not shown). This drive device can be an integral Be part of the reclining device 1.

FIG. 3 shows, in a schematic side view similar to FIGS. 1 and 2, the reclining device 1, as compared to the flat positions shown in FIGS. 1 and 2, is pivoted upwardly. In Figure 3, the contour of the back part 4 to 7 is formed so that the user assumes a kyphosis. Figure 4 illustrates the Lordosestellung in this erected position. Again, this back part 2 may be discontinuous or continuously adjustable.
FIG. 5 illustrates a continuous, dynamically oscillating adjustment of the reclining device 1 between the position shown in FIG. 1 and in FIG. In contrast, FIG. 6 illustrates a dynamic adjustment variant, in which the oscillating adjustment of the back part 12 between the position shown in FIG. 3 and in FIG. 4 is accompanied by a tilt adjustment of the back parts 5 and 6. The two positions in the maximum deflected positions of the reclining device are denoted by 5 and 6 or 5 'and 6'.

In Figure 5 and Figure 6 is also a different Position of the leg parts 2 and 3 to recognize in the same way as the back part discontinuous and continuous between different Positions with adjustable frequency and Amplitude are movable.

In Fig. 7 is a reclining device according to the invention 1 shown. This lying device has a Base frame 10, on which a total of six movable Frame sections 12 to 17 are arranged. The Frame sections 12 and 13 correspond to one Leg rest area and the sections 14 to 17 a Support area for the back and head of a human. Each of these bearing areas 12 to 17 has one or several Querlattungen 11 on which a mattress can be placed. So it is so far around a conventional slatted frame. According to the invention However, these slats 11 are not fixed to the Frame 10 attached but partially on the movable Frames 12 to 17, both in their height as well as their inclination adjusted independently can be. This is done via a below of the slatted frame located mechanism. Especially In the lumbar region, a lath is 18 in arranged the movable frame 14, in turn be highlighted from the plane of the other slats can. This is also done via a below the Bed arranged mechanism, for example, a through a motor driven scissors mechanism. Becomes this bar raised 18 now, so the arched bulges overlying mattress, which is characterized by the Stiffness of the mattress a smooth transition between the individual heights of the slats. By Lifting the batten 18 can thus cause the spine of the man lying on the mattress in lordosis position to be brought.

FIG. 8 shows the mechanics in three partial images A, B and C. the lying device 1 according to the invention Fig. 7. It can be seen that below the Bed 1 is a mechanic 21 which is used for adjusting the individual frame sections 12 to 17 suitable is. In Fig. 8a is a view of the bed of below, in Fig. 8b from the head side in cross section and in Fig. 8c in the side view along the Long side shown. In Fig. 8c can be seen that the head part 12 is movable up and down, for example a hyperextension of the cervical spine in to achieve the downwardly inclined position. The Adjustability of the head area can, for example also for setting an anti-snoring position or an anti-sleep apnea position. According to the invention can in such a case in the Lying device also a sensor for snoring sounds or sleep apnea are incorporated, so that at Occurrence of snoring or sleep apnea the Head area 12 adjusted accordingly, if necessary is cyclically moved and thereby the snoring or the apnea is eliminated.

FIG. 9 shows the same lying device according to the invention, whereby the individual areas 2 to 7 are raised in this way and are inclined that the one thereon Man in a sitting position with high-altitude Legs would be located. Good to see are the moving Frame 12 to 17, by adjusting mechanisms 22 to 27 brought into their position and held become. Furthermore, that is also for the Lordosenstellung responsible latte 18 and her mechanics 28 to recognize.

In Figure 10, this lordosis position of the reclining device illustrated. In this figure, all movable frame 12 to 17 in a flat position, as for example for the sleep of a person is common. For this profile is highlighted but the lath 18 by means of the scissors mechanism 28, which is located in the movable frame 15. In this position of the crossbar is the mattress lifted up on this spot, so that the one on it Lying back man takes a Lordosenstellung. According to the invention can now, for example, this Latte 18 automatically moved up and down in oscillating Way, so that the spine of it people constantly between Lordosenstellung and kyphosis position is moved back and forth. This leads to the desired beneficial effects on the spine of man.

In Fig. 10, a complete bed is shown, the also bedpost 19 has.

According to the invention, therefore, all movable Frame 12 to 17 or the bar 18 in periodic Automatically through the reclining device moved back and forth between different positions become.

The optimal reversal points for the individual movements can be determined by, as in Fig. 11, the maximum possible deflections of the spine of the People are determined. In Fig. 11 are three extreme positions the spine represented, with with the reference numeral 30, the normal position of the spine standing person, with reference 31 the maximum backward inclined position and with reference numerals 32 the maximum forward inclined position of the human being.

FIG. 12 shows an evaluation of this measurement Fig. 11, wherein in Fig. 31, the mobility of each individual vertebrae in the maximum supine position (lordosis position) and at 32 the mobility of the spine in the maximum forward position (kyphosis position) being represented. Such a measurement For example, by means of the measuring system CMS30 / 70P and the program WinSpine of the company Zebris Medizintechnik GmbH, Isny, Germany become. So are the maximum deflection points of the Spine determined, so the inventive Lying device are programmed so that they movable frame 12 to 17 and the bar 18 so moved back and forth, that the spine of it lying humans between their two maximum Displacement values is moved back and forth. Thereby will exercise the spine and other joints achieved. To program the reclining device, can this with a reader (data collection device) be provided, for example a Chip card reader, a data input device (for example Hand switch), an infrared interface or like. So the reclining device can be used on everyone individual people are hired or too in the course of a person's life constantly its anatomical Be adapted to circumstances.

Figures 13 to 18 show such different ones Motion specifications for a motor control of an inventive Lying device, as shown in the figures 7-10 is shown.

The parameters of the individual exercise programs are individually to the anatomical and biomechanical Properties of the user. Depending on the constitution, Mobility or rigidity of the spine, Health condition or special problems some exercise programs are not allowed or need be customized (rigid knee or stiff hip, osteoporosis, bechterew, dizziness, Etc.).

For this purpose, a smart card or a handset be programmed, these individual programs for the control of the individual joints of the lying device contains. To this chip card or hand switch To program individually, the customer must (User of the bed) first complete a questionnaire, where his relevant data is collected. This is followed by a motion analysis with a motion analysis system as described above. First when standing upright (Fig. 11) by means of a Stylus starting at the vertex above the back of the head the entire spine contour is detected. This measurement becomes prone to postponing (flexion) and retarding (Extension) repeated (Fig. 11). Based on this three records can be a difference Mobility of individual spinal regions determined which are the different amplitudes of the Determine couch device (see Fig. 12). measure is also body size, weight, shoulder width, etc. These data are corresponding to the computer program converted to a frame size and suggest to the individual height and stiffness adjustment to determine each bar of the slatted base.

The nutrition of the disc, the cartilage in the small vertebral joints, but also in the hip and knee joint depends on the amplitude and frequency. This could e.g. be detected on bone cells (Neidlinger-Wilke C., Wilke H-J, Claes L. Cyclic Stretching of Human Osteoblasts Effects Proliferation and Metabolism: a New Experimental Method and its Application Journal of Orthopedic Research, No. 12 pp. 70-78, 1994). This could be the case with osteoporotics or other problems, however (Neidlinger-Wilke-C; Insta-I; Claes-L; Brand-R; Dens-I; Rübenacker-S; Arand-M; Kinzl-L Human osteoblasts from younger normal and osteoporotic donors show differences in proliferation and TGF beata-release in response to cyclic strain J. Biomechanics 28: 1411-1418 (1995)).

Furthermore, these different programs can be of different duration.

  • If, for example, back pain occurs at night, the bed user no longer has to get up and walk for a few minutes so that the spine is moved, but he runs a program that moves his lumbar spine cyclically. This program should turn off automatically after 15 minutes and drive the bed in the normal sleeping position (memory position).
  • Also conceivable are movements of the various joints with very small amplitudes throughout the night.
  • In bedridden patients, for example, a particular individual program can run throughout the day.
  • In the reading position, if desired, a certain sequence of movements can take place over a period of 1 hour, back pain, which force the user to change position, no longer occur. That is, you can stay longer than usual in the erect reading position.
