Description

The invention relates to a therapy device according to the preamble of patent claim 1, a method for operating such a therapy device and a trolley with such a therapy device. A therapy device of the type mentioned is, for example DE 20 2008 001 590 U1 known.

DE 20 2008 001 590 U1 describes a multifunctional training device for human gait variants, comprising two movement devices, each movement device is associated with a lower limb of a patient to be treated. The movement devices each comprise a carriage, which is displaceable along a longitudinal guide. On the carriage a multi-joint kinematics is arranged, which carries a foot plate. The foot plate forms a holding means for fixing a lower extremity. The longitudinal displacement of the carriage along the linear guide is effected by a linear drive, which is designed substantially as a rotary spindle drive. A pulley-type belt drive allows the tilting movement of one of the kinematic joints that transfers to the footplate so that different degrees of rotation of the foot can be adjusted.

Due to the complicated construction of the kinematics chain, the control of the known training device is relatively complex. In particular, it is difficult to map complicated movement patterns. Another disadvantage of the known training device is that the training device is only suitable for training in an upright position. A use in bedridden patients is therefore not possible. However, this is especially desirable in the rehabilitation training of neurologically damaged patients, in particular stroke patients.

An acute stroke (apoplexy) is often associated with hemiplegia (hemiparesis). This degenerates the muscles in the paralyzed extremities. The treatment of such, usually high-grade weakness of the lower extremities is difficult and often unsuccessful. Conventional physiotherapy is only possible after the acute stage of the disease, when the patient can leave the hospital bed. In addition, conventional physiotherapy is laborious and usually aims to relieve spasticity of the muscles and practice pre-sitting exercises both while sitting and standing, for example, to strengthen weight bearing on the affected leg.

Modern, scientific concepts of the rehabilitation of stroke patients on the other hand favor a repeated practice of individual movement sequences of walking with the feet and legs already in the acute phase, ie in the acute care bed. In stroke patients it has been shown that the repeated movement of the affected extremities already in the acute phase is beneficial for the recovery of the motor functions. In addition, it is common knowledge from practice that bilateral training of both the healthy and the weakened limb leads to better results. The co-movement of the non-weakened side, ie the side that is not affected by hemiplegia, positively influences the activation of the brain structures responsible for the use of the paralyzed limb in the parietal lobe.

The positive effect of training the lower extremities in the acute phase has already been recognized and implemented in training devices known from practice. For example, training devices are known which have a couch on which movement devices, such as cranks are attached, so that a training of the lower extremities is made possible while lying down. However, such devices on the one hand have a high space requirement, which leads to additional costs for the provision of equipment in the hospital or in the rehabilitation facility. Moreover, the handling of the equipment is complex, because the patient must be transferred from the acute care bed on the couch. Since stroke patients are subject to restricted mobility in the acute phase, the relocation is usually carried out by nurses, which represents a relatively high level of physical stress for the nursing staff.

From the prior art further mechanical and electromechanical devices for the therapy of the healthy and the weakened side of the lower extremities are known. This is exemplified DE 36 18 686 A1 . DE 81 09 699 U1 . DE 20 2008 013 423 U1 and DE 195 29 764 A1 directed. Therein, therapy devices are disclosed which have cranks. The cranks must be operated by the patient himself and allow only asynchronous tracking of the weakened limb. Asynchronously tracking movements, however, do not reflect the variety of real movements. The desired transfer of the learning effect in connection with movements of the brain flap of the healthy side on the brain lobe of the affected side is only partially possible. In the known pedal crank assemblies variable motion sequences due to the rigid mechanical connection of the pedal crank or pedals are excluded.

Furthermore, therapeutic robotic systems with control units are known which reduce the forces of the Measure patients during exercise. By means of different evaluation algorithms, minimum own movements or applied forces can be measured and the determined parameters can be compared with predetermined movement sequences. Such robot systems are for example off DE 100 28 511 A1 . DE 10 2006 035 715 A1 and DE 10 2009 022 560 A1 known.

The invention has for its object to provide a therapy device for training of lower limbs of a human, which is simple and compact and easy to handle. In particular, should be possible with the therapy device training while lying down. A further object of the invention is to provide a method for operating such a therapy device and a trolley with such a therapy device.

According to the invention this object is achieved with regard to the therapy device by the subject-matter of patent claim 1, with regard to the method by the subject-matter of claim 9 and with regard to the transport carriage by the subject-matter of claim 10.

The invention is based on the idea to provide a therapy device for training lower limbs of a human with a frame and independently movable movement means, each having a holding means for fixing a limb which is rotatably coupled to a carriage. The carriage is slidable along a linear guide attached to the frame. The movement devices each comprise two flexible transmission means, which are guided over deflection rollers mounted on the frame and extend at least in sections parallel to the linear guide. A first transmission means connects the carriage with a linear drive, so that the carriage is movable along the linear guide. A second transmission means couples a rotary roller of the holding means with a rotary drive, so that the holding means is rotatable.

The therapy device according to the invention is particularly simple and compact. This advantageously allows a mobile use of the therapy device. In other words, the therapy device can be used not only in a seated patient, but in particular in the acute phase in bedridden patients. Due to the compact dimensions and the simple mechanism, it is possible to use the therapy device according to the invention directly in the acute care bed or hospital bed. A special additional lounger is therefore not required. Also, the rearrangement of the patient is avoided with the therapy device according to the invention.

In contrast to known systems in which the patient must be brought to the therapy device, the therapy device according to the invention is so compact and mobile that it can be brought to the patient. Due to the comparatively simple mechanism, the maintenance effort is additionally reduced. Despite the simple construction, a multiplicity of different movement sequences can be realized with the therapy device according to the invention. In this way, a successful therapy can be carried out by frequent repetition of exercise procedures. Since the different movement sequences can be set differently for both independently movable movement devices, the therapy device also enables a transmission of learning effects from the brain side responsible for the healthy limb to the brain side responsible for the weakened limb or the respectively responsible brain area. Moreover, the therapy device allows the strengthening of the leg and back muscles, which also brings benefits in the recovery even in the treatment of advanced patients or for the training of healthy people.

Overall, the therapy device according to the invention allows a bilateral or alternating therapeutic movement of the lower limbs of a person sitting or lying, just because of the independently movable movement means without having to mobilize the patient from the wheelchair or from the bed. The course of the movement runs linearly along the predetermined direction of movement, ie along the linear guide in order to realize the flexion and extension in the hip and knee joint. Additionally or alternatively, the holding means, thus also the foot mounted on the holding means, can be rotated in order to realize the plantar and dorsiflexion.

In a preferred embodiment of the therapy device according to the invention, the frame is designed in the form of a right-angled triangle, wherein the movement devices are arranged on the hypotenuse. This particular shape of the frame makes it possible in a particularly simple manner to change between a position of the therapy device in which a patient is treated while sitting, and a position of the therapy device in which a patient is treated lying down.

Specifically, it may be provided that the frame has two legs arranged perpendicular to one another and a cross-member connecting the legs, wherein the linear guides are fastened to the cross-member. The legs may form the footprints of the therapy device, wherein one of the legs rests on a floor or generally a pad when the therapy device is used for the sedentary therapy and another of the both legs rest on the floor or the base when the therapy device is used for lying therapy.

Preferably, the legs have different leg lengths. This ensures that the cross-beam with each of the two legs each includes a different sized angle. In particular, the leg lengths are set such that between the leg, which forms the base for the seated therapy, and the cross-beam is a greater angle than between the cross-beam and the leg, which forms the base for the lying therapy. In this way, comparatively realistic movement patterns can be adjusted.

In a preferred embodiment of the therapy device according to the invention, the transmission means are designed as belts, in particular as toothed belts, or as a chain. Such transmission means allow a particularly simple and lossless power transmission from the linear drive or rotary drive to the carriage or the holding means.

In general, the linear drive and the rotary drive can be controlled independently of each other. In particular, it is provided that different speeds can be set on the linear drive and on the rotary drive, so that the holding means is rotated. Alternatively, same speeds can be set on the linear drive and on the rotary drive, so that the holding means is held level with the same.

In the therapy device according to the invention, the transmission means for the rotational movement of the holding means and for the linear movement of the carriage on the one hand parallel to each other and on the other hand parallel to the linear guide of the carriage. The first transmission means, which is connected to the carriage, causes the linear movement of the carriage along the linear guide. If the second transmission means, which engages in the rotary wheel of the holding means, at the same speed as the first transmission means is moved, takes place between the holding means and the carriage no relative movement, in particular no relative rotation. The holding means is thus kept level and moves together with the carriage linearly along the linear guide. A rotation of the holding means, ie a relative movement between the holding means and the carriage, is effected by a relative movement between the first transfer means and the second transfer means. By different speeds of the linear drive and the rotary drive so both the speed, as well as the degree of rotation of the holding means can be adjusted. In this way, complex movements can be adjusted by relatively simple control parameters, namely only by varying the speed of the linear drive and the rotary drive.

In order to ensure that the second transmission means is in constant engagement with the rotary roller, it is provided in a preferred embodiment of the invention that the rotary roller is arranged between two tension rollers which are rotatably mounted on the carriage and engaged with the second transmission means.

According to a sidelined aspect, the invention is based on the idea to provide a method for operating a previously described therapy device in which the linear drive at a first speed and the rotary drive are driven at a second speed, the speeds for holding the same holding means equal and the same Rotate the holding means are set differently.

Another secondary aspect of the invention relates to a trolley with a previously described therapy device and a lifting device which has an extendable lifting plate for receiving the therapy device. On the lifting plate, a tilting element is attached, which is connected to the frame of the therapy device such that the therapy device from a first position in which a first leg of the frame is arranged horizontally, is tiltable to a second position in which a second leg of the Frame is arranged horizontally. The second leg may be aligned perpendicular to the first leg of the frame.

The lifting device facilitates handling of the therapy device insofar as the therapeutic device can be easily lifted into the acute care bed or general hospital bed by the lifting device, for example, simply and without the physical exertion of an operator. The tilting element makes it possible in a simple manner to bring the therapy device into different positions, wherein the therapy device in the first position is particularly suitable for the therapy of sedentary patients and in the second position for the therapy of recumbent patients.

The invention is explained in more detail below with reference to an embodiment with reference to the accompanying schematic drawings. Show in it

1 shows a perspective view of a therapy device for training of lower limbs of a human and / or for therapeutic treatment, the therapy device is particularly suitable for training the lower extremities of neurologically damaged patients. The therapy device has two independently movable movement devices 10a . 10b on that in a frame 22 are integrated. The movement devices 10a . 10b each comprise a holding means 19a . 19b , The holding means 19a . 19b is used to attach a lower extremity of a human, especially a foot. The holding means are each formed as foot plates and have bindings in which the feet of the patient or the person to be trained can be held.

The holding means 19a . 19b are each rotatable on a carriage 16 stored. In other words, each of the two movement devices 10a . 10b a sled 16 on, which is a holding means 19a . 19b wearing. The holding means 19a . 19b is rotatable with the carriage 16 coupled.

The sledge itself is at one on the frame 22 fasten arranged linear guide or along the linear guide 15 slidably mounted. The linear guide 15 is formed by a rail. The sled 16 surrounds or at least partially engages behind the rail. In other words, the sled 16 positive locking with the linear guide 15 connected.

The holding means 19a . 19b is fixedly connected to a rotary axis, which is in a pivot bearing of the carriage 16 is arranged and on the holding means 19a . 19b opposite side of the carriage 16 a rotation roll 17 wearing. In other words, the rotary role 17 firmly with the holding means 19a . 19b connected. Further, on the sled 16 two tension rollers 23 rotatably mounted, wherein the rotary roller 17 between the two tension rollers 23 is arranged.

The movement devices 10a . 10b each have two pulleys 18 on, rotatable on the frame 22 are stored. The pulleys 18 are each at the free ends of two mutually perpendicular legs 31 . 32 of the frame 22 arranged. The linear guide 15 is between the pulleys 18 the respective movement device 10a . 10b arranged.

Specifically, the longitudinal guides 15 on a crossbeam 33 of the frame 22 attached. The crossbar 33 extends between the thighs 31 . 32 of the frame 22 , In general, the frame points 22 the shape of a right triangle, with the legs 31 . 32 the catheters and the crossbar 33 form the hypotenuse. The first leg 31 of the frame 22 has a leg length that is shorter than the leg length of the second leg 32 is. This ensures that between the first leg 31 and the cross-beam is a smaller angle than between the cross-beam 33 and the second leg 32 , The first leg 31 preferably lies flat, in particular horizontal, on a base or the floor when the therapy device is used in a seated patient. Here are the linear guides 15 arranged comparatively steep, so that the therapy device is well adapted to the sitting position of the patient. In contrast, the therapy of a recumbent patient is the second leg 32 flat, in particular horizontal, arranged on a base, so that the linear guides 15 rise relatively flat.

The movement devices 10a . 10b each comprise a linear drive 11 and a rotary drive 12 , The linear drives 11 and the rotary drives 12 are on the side of the frame 22 arranged, as from the 1 and 3 is clearly recognizable. In particular, the linear drives 11 and the rotary drives 12 in the area of the right angle between the thighs 31 . 32 of the frame 22 arranged.

The movement devices 10a . 10b also each have two flexible transmission means 13 . 14 on. The transmission means 13 . 14 are formed in the illustrated embodiment as a belt, in particular toothed belt. Alternatively, one or more transmission means 13 . 14 be designed as a chain.

In 4 is in each case the course of the first transmission means 13 and the second transmission means 14 of both movers 10b recognizable. The first transmission medium 13 grabs the sled 16 on and runs over a pulley 18 to the linear drive 11 , The linear drive 11 has a drive roller 11a on, the, as well as the pulleys 18 , is designed as a toothed roller or gear. The teeth of the toothed belt, which is the first transmission medium 13 forms, engage in the teeth of the gears or sprockets. In the further course, the first transmission means surrounds 13 a scroll 11b a tensioning device 20 , where the adjusting roller 11b has a smooth roller surface. The scroll 11b allows retightening of the first transmission means 13 or the toothed belt. The first transmission medium 13 extends from the actuating roller 11b over another pulley 18 on the first leg 31 of the frame 22 is stored, continues to slide 16 and is attached to this.

The second transmission means 14 that the holding agent 19b with the rotary drive 12 connects, is designed as a closed belt. Starting from a drive roller 12a the rotary drive 12 the second transmission means runs 14 via a control roller 12b the tensioning device 20 to a pulley 18 on the first leg 31 of the frame 22 is stored. From the pulley 18 on the first leg 31 the second transmission means extends in the direction of the carriage 16 , wherein the second transmission means 14 on a tension pulley 23 deflected and over the rotary roller 17 is guided. The second transmission means 14 stands with about half the peripheral surface of the rotary roller 17 in contact or engaged. In the further course, the second transmission means 14 on another tensioner 23 on the sled 16 is stored, deflected and extends to another pulley 18 on the second leg 32 of the frame 22 is stored. From the pulley 18 on the second leg 32 extends the second transmission means 14 essentially along the second leg 32 to the drive roller 12a the rotary drive 12 , The drive roller 12a , the pulleys 18 as well as the rotation roller 17 into which the second transmission means 14 engages are designed as toothed rollers or gears. The scroll 12b and the tension rollers 23 On the other hand, they are formed as smooth rollers since they are the back of the toothed belt, which is the second transmission means 14 forms, leads.

Between the pulleys 18 the transmission means run 13 . 14 at least in sections parallel to the linear guide 15 , In this case, the transmission means 13 . 14 arranged side by side, like 3 clearly shows. In this context, it should be noted that in each case one of the two movement devices 10a for clarity, without the means of transmission 13 . 14 is shown. This is true at 3 for the movement device 10a , which is shown in the left half of the picture.

The mode of operation of the therapy device is explained in more detail below:
The linear drive 11 , which is preferably designed as an electric motor, in particular stepping motor, acts via a translation device 21 on the drive roller 11a that with the first transmission means 13 is engaged. The first transmission medium 13 transfers the driving force of the linear motor 11 turn on the sled 16 , which corresponds to the movement of the linear drive 11 along the linear guide 15 emotional. About the direction of rotation of the linear drive 11 and the rotational speed may be the travel or travel direction and the travel speed of the carriage 16 along the linear guide 15 to be controlled. Because the movement facilities 10a . 10b each completely independently operable linear actuators 11 have, are the sledges 16 of the two movement devices 10a . 10b completely independently movable.

The rotary drive 12 , which is also preferably designed as an electric motor, in particular stepper motor, acts via a further transmission device 21 on the drive roller 12a the movement device 10a . 10b , In the drive roller 12a the rotary drive 12 picks up the second flexible transmission medium 14 a, which is the driving force of the rotary drive 12 to the rotary roller 17 transfers. By controlling the drive direction and drive speed of the rotary drive 12 Thus, the direction of rotation and rotational speed of the rotary roller 17 be determined. Because the rotary roller 17 directly with the holding means 19a . 19b coupled, the rotational movement and rotational speed of the holding means 19a . 19b in relation to the sledge 16 to be controlled.

The transmission means 13 . 14 parallel to each other along the cross-beam 33 of the frame 22 , It follows that by a simultaneous movement of the transmission means 13 . 14 at the same speed, on the one hand, the carriage 16 along the linear guide 15 shifted and on the other hand at the same time the holding means 19a . 19b is kept equal. Decisive is thus the relative movement between the transmission means 13 . 14 , Is the relative velocity between the transmission means 13 . 14 along the crossbar 33 equal to zero, becomes the holding means 19a . 19b not rotated. Once between the transmission means 13 . 14 a relative speed not equal to zero or a speed difference is set, there is a rotation of the holding means 19a . 19b depending on the relative speed. In this way, in the inventive therapy device only by the control of direction and Speed of the linear drive 11 and the rotary drive 12 different movement patterns are simulated. On the one hand, this simplifies the design effort for the therapy device and, on the other hand, the control of the drives 11 . 12 ,

The therapy device allows treatment of sedentary patients as well as treatment of recumbent patients. In the treatment of sedentary patients is the second leg 32 of the frame 22 preferably aligned horizontally. In the treatment of lying patients, however, the first leg 31 aligned horizontally or the therapy device on the first leg 31 posed.

To relieve the operator or the therapist who operates the therapy device, a trolley is provided, which carries the therapy device. An embodiment of such a dolly is in the 5 and 6 played. The 5 and 6 show a mobile trolley on wheels, a lifting plate 24 has, on which the therapy device is mounted. The lifting plate 24 is also with a Hubführungsschlitten 26 connected, along a lifting guide 25 is displaceable. The lifting guide 25 preferably extends vertically and is perpendicular to the Hubführungsschlitten 26 extendable.

The lifting plate 24 is perpendicular to the Hubführungsschlitten 26 aligned, so that a longitudinal movement of the Hubführungsschlittens 26 along the vertical lifting guide 25 a change in the altitude of the lifting plate 24 causes. To move the Hubführungsschlittens 26 along the lifting guide 25 is a crank 30 provided, which is operated by hand.

The lifting guide 25 is on a cart frame 29 attached, which also carries the wheels over which the trolley rolls on the ground. On the lifting plate 24 Furthermore, a Drehkippgelenk is arranged, which is a rotary member 27 and a tilting element 28 includes. The tilting element 28 is with the second leg of the frame 22 rotationally connected to the therapy device. As from the synopsis of 5 and 6 is clearly recognizable, is the therapy device on the tilting element 28 from a first position, in which the second leg is arranged horizontally, tiltable in a second position, in which the first leg 31 is arranged horizontally. In the first position, the therapy device can be used for the therapy of a recumbent patient. In the second position, sitting patients can be trained. The rotary element 27 allows the twisting of the therapy device on the lifting plate, for example, to adapt it to a patient lying obliquely in bed.

The trolley is particularly helpful in the treatment of recumbent patients. In this case, the trolley with lifted lifting plate 24 moved laterally to a patient bed. Subsequently, the lifting plate 24 lowered to the bed level and extended accordingly far to position the located in the first position therapy device in bed, especially on the mattress. The lower extremities of the patient to be treated can now on the holding means 19a . 19b attached and then set the therapy device in motion.

The therapy device according to the invention enables a particularly variable and flexible therapy or a particularly variable and flexible training of the lower extremities. At the same time the therapy device according to the invention is simple and compact and therefore provides good access to the patient. The transport vehicle further facilitates the handling of the therapy device and in particular relieves an operator of the therapy device, in particular a therapist or physiotherapist.
