Definitions
- the present invention relates to a length adjustment device for a finger movement splint of a therapy device for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand; a finger movement splint for carrying out such a movement with such a length adjustment device and a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, comprising at least one such finger movement splint.
- the present invention also relates to a method for adjusting the length of a finger movement splint on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand.
- Therapy devices with finger movement splints for the automated movement of individual and/or multiple fingers of a hand enable controlled joint mobilization regardless of the availability of physiotherapy staff. Through automated training that is independent of the time of day and individually tailored to the respective user, such devices improve the success of therapy in a cost-effective manner and shorten the user's recovery time.
- JP 2011 115 248 A and in the US 2014/028 86 64 A1 Devices for supporting finger movement are disclosed, the movement mechanism of which is arranged laterally next to the respective fingers, so that movement restriction by resting on the finger is avoided.
- the JP 2011 115 248 A discloses a device for supporting a movement, in particular a finger movement splint, which is said to be able to set a three-joint region to a natural bent position.
- a finger movement support device which uses sensor technology to determine the user's intention regarding a desired finger movement ("bending or stretching") and then supports this movement with the help of piezoelectric drives arranged on each finger joint.
- both devices can only be inadequately adapted to the differentiated anatomical shapes of the fingers or thumbs of different patients, which means that the automated movement of the fingers performed by them can deviate relatively significantly from a natural movement.
- a portable exoskeleton training robot for hand rehabilitation has become known.
- This training robot includes a fixation device for the hand, which can be attached to the back of the hand and the wrist, and rehabilitation devices for the fingers and thumb.
- the rehabilitation devices are each driven by linear motors.
- Threaded rods are available which allow at least manual length adjustment for each individual rehabilitation device.
- the EN 11 2017 000 012 B4 a therapy device for carrying out a continuous, passive and/or actively assisted movement of the fingers and thumb of a patient's hand, which allows each selected finger to be provided with its own finger movement splint with movement kinematics, which are arranged laterally to the finger to be treated and provide it with a allows for unrestricted bending and/or stretching movements.
- the well-known finger movement splint is based on a slide-rail movement kinematics, which enables an automated finger movement that is very close to an anatomically natural finger movement.
- a finger movement splint or a therapy device is described, the movement kinematics of which include a multi-joint hinge as a means of bending a metacarpophalangeal joint and is therefore particularly robust against the effects of axial forces and torsional forces on the finger movement splint.
- the movement principles of both of the aforementioned publications are hereby expressly referred to in full.
- the device in particular the individual finger movement splints, must be adjusted to the respective anatomy, i.e. to the hand size and/or the individual finger dimensions, before training begins.
- the individual finger movement splints are usually attached manually to the upper shell or holder of the respective therapy device in the optimal position for the respective user.
- the finger movement splints must then be manually removed after a training session and manually reattached in a different place for the next user. This procedure is time-consuming and, in everyday clinical practice, adversely reduces the training time available to the respective user with the therapy device.
- the object of the present invention is therefore to provide a device or a method which carries out the adaptation of a finger movement splint or a corresponding therapy device to the anatomy of the respective user quickly and cost-effectively in an automated manner.
- a length adjustment device for a finger movement splint of a therapy device for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand with the features of patent claim 1; by a finger movement splint for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand with the features of patent claim 11; by a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or thumb of a hand with the features of patent claim 12; and by a method for adjusting the length of a finger movement rail on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or thumb of a hand with the features of patent claim 14.
- the carriage can preferably be operatively connected directly to the drive.
- the carriage can also be operatively connected indirectly to the drive via at least one connecting element.
- An embodiment in which the carriage can be operatively connected directly to the drive, in particular via a direct operative connection to a spindle of the drive, enables a comparatively simple construction of the length adjustment device, whereas an embodiment in which the carriage can be operatively connected indirectly to the drive via at least one connecting element promotes a comparatively compact, in particular flat construction of the length adjustment device.
- the adjustment rail is preferably a grid track with at least two grid elements.
- a grid track with at least two grid elements advantageously enables the holding means and thus also the finger movement rail to be locked onto the therapy device in a simple manner.
- the at least two grid elements protrude from the plane of the adjustment rail in a substantially wedge-shaped (triangular) and/or semicircular and/or in the form of a circular arc triangle (so-called "Reuleaux triangle”).
- Grid elements that protrude from the plane of the adjustment track in this way advantageously enable positive locking, whereby in the case of a wedge (triangular) shape and/or a semicircular shape and/or the shape of a circular arc triangle (so-called "Reuleaux triangle shape”) the effect of the blocking mechanism can be overcome more easily (with less effort) by exerting force using the slide than would be the case, for example, with grid elements that protrude from the plane in a cuboid shape.
- the at least two grid elements can also be designed as holes within the adjustment rail.
- An adjustment rail with holes as grid elements in the sense of a perforated plate advantageously enables a flatter construction of the adjustment rail.
- the holding means preferably has a first side wall for holding the blocking mechanisms and a second side wall for holding the finger movement rail, which are connected to one another at least via a base element, thereby forming a substantially U-shaped cross section through which the adjustment rail runs.
- a substantially U-shaped holding means advantageously enables simple and cost-effective production, depending on the material selected, for example by bending a metal sheet, by injection molding or 3D printing. In addition, such a holding means can easily be moved along the adjustment rail as a guide.
- the adjustment rail comprises a first side wall and a second side wall along its longitudinal axis, wherein the first side wall, the adjustment rail and the second side wall together form a substantially U-shaped cross section, and wherein the holding means is arranged to be movable within the substantially U-shaped cross section with respect to the adjustment rail.
- the blocking mechanisms each comprise at least one fixing means arranged on the holding means, preferably on the first side wall; a blocking lever pivoted on the holding means, preferably on the first side wall, via a rotation axis; and a means for springing the blocking lever relative to the fixing means, wherein the blocking lever is designed such that when the carriage comes into operative connection with the blocking lever, the blocking lever is rotated from a blocking position to an unblocking position and the holding means is thereby movable in at least one direction.
- a blocking mechanism advantageously enables a change in position of the holding means caused by the carriage and thus the drive of the finger movement rail and the the finger movement rail held by the holding device along the adjustment rail on the therapy device.
- the blocking mechanisms can also be designed as a single piece and made from a resilient material, in particular spring steel and/or hard rubber.
- the fixing means and the blocking levers can advantageously be made from a single piece of resilient material, with the blocking levers being arranged at an angle to the fixing means and the intersection points between the blocking levers and the fixing means corresponding to the axes of rotation.
- the means for suspension can be replaced by the spring properties of the resilient material, in particular the spring steel and/or the hard rubber, itself, which advantageously saves one component per blocking mechanism and reduces the size of the blocking mechanism.
- the blocking levers are operatively connected to the adjustment rail in their respective blocking position, in particular to the grid elements of an adjustment rail designed as a grid track, and in their respective unblocking position are not operatively connected to the adjustment rail, in particular to the grid elements of an adjustment rail designed as a grid track. If the blocking levers are operatively connected to the adjustment rail, in particular to the grid elements of an adjustment rail designed as a grid track, a movement of the holding means along the adjustment rail is advantageously prevented and the finger movement rail is held stable and securely in one position so that the therapy movement can be carried out safely.
- the holding means can advantageously be moved along the adjustment rail to any position or, in the case of an adjustment rail designed as a grid track, to a position depending on the grid elements or the holes.
- the present invention also relates to a finger movement splint for performing a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand, comprising a length adjustment device according to one of claims 1 to 10.
- the present invention also relates to a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, comprising at least one drive for a finger movement rail and at least one finger movement rail according to claim 11.
- the drive is a linear drive, in particular a spindle motor, a pneumatic cylinder, a hydraulic cylinder and/or a cable pull.
- a linear drive advantageously enables a controlled movement of the carriage and thus both the finger movement rail during the execution of the therapy movement and the holding means together with the finger movement rail during length adjustment along the adjustment rail.
- the present invention relates to a method for adjusting the length of a finger movement rail on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, which is characterized in that a connecting element of a finger movement rail arranged on a holding means is moved with the aid of a drive via a carriage along an adjustment rail from an amplitude for a therapy movement into a first or second adjustment range; wherein the carriage, when moved by means of the drive in a first direction along the adjustment rail into the first adjustment range, exerts a force on the first blocking mechanism upon contact with a first blocking mechanism, so that the first blocking mechanism is released and the holding means together with the finger movement rail is moved by movement of the carriage in the first direction, and wherein the carriage, when moved by means of the drive in a second direction along the adjustment rail into the second adjustment range, exerts a force on the second blocking mechanism upon contact with a second blocking mechanism, so that the second blocking mechanism is released and the holding means together with the finger
- a length adjustment device advantageously makes it possible to automatically move a finger movement rail along an adjustment rail using the drive already present for the finger movement rail on a therapy device and to fix it in a desired position - depending on the finger length or hand size/length of the user - on the adjustment rail and thus on the therapy device in order to then be able to carry out a continuous, passive and/or actively assisted movement of a finger and/or thumb of a hand in a stable position. Time-consuming manual adjustment is thus advantageously avoided.

Time-consuming manual adjustment is thus advantageously avoided.

Description
Die vorliegende Erfindung betrifft eine Längeneinstellvorrichtung für eine FingerBewegungsschiene eines Therapiegeräts zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung eines Fingers und/oder eines Daumens einer Hand; eine Finger-Bewegungsschiene zur Durchführung einer derartigen Bewegung mit einer solchen Längeneinstellvorrichtung sowie ein Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung wenigstens eines Fingers und/oder eines Daumens einer Hand, umfassend wenigstens eine solche FingerBewegungsschiene.The present invention relates to a length adjustment device for a finger movement splint of a therapy device for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand; a finger movement splint for carrying out such a movement with such a length adjustment device and a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, comprising at least one such finger movement splint.
Darüber hinaus betrifft die vorliegende Erfindung auch ein Verfahren zur Längeneinstellung einer Finger-Bewegungsschiene auf einem Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung wenigstens eines Fingers und/oder eines Daumens einer Hand.Furthermore, the present invention also relates to a method for adjusting the length of a finger movement splint on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand.
Therapiegeräte mit Finger-Bewegungsschienen zur automatisierten Bewegung einzelner und/oder mehrerer Finger einer Hand ermöglichen eine kontrollierte Gelenkmobilisation unabhängig von der Verfügbarkeit von physiotherapeutischem Personal. Durch ein tageszeitunabhängiges und individuell auf den jeweiligen Benutzer abgestelltes automatisiertes Training, verbessern derartige Geräte auf kostengünstige Weise den Therapieerfolg und verkürzen die Genesungszeit des Benutzers.Therapy devices with finger movement splints for the automated movement of individual and/or multiple fingers of a hand enable controlled joint mobilization regardless of the availability of physiotherapy staff. Through automated training that is independent of the time of day and individually tailored to the respective user, such devices improve the success of therapy in a cost-effective manner and shorten the user's recovery time.
Bislang sind eine Reihe von derartigen Therapie- und Trainingsgeräten bekannt geworden, welche sich u.a. in der Art und Weise, wie auf die Fingergelenke der Finger automatisiert Kraft ausgeübt wird, unterscheiden. In der
Beide Vorrichtungen lassen sich allerdings aufgrund ihres Bauprinzips nur unzureichend an die differenzierten anatomischen Formen der Finger bzw. Daumen verschiedener Patienten anpassen, wodurch die durch sie ausgeführte automatisierte Bewegung der Finger von einer natürlichen Bewegung relativ stark abweichen kann.However, due to their design, both devices can only be inadequately adapted to the differentiated anatomical shapes of the fingers or thumbs of different patients, which means that the automated movement of the fingers performed by them can deviate relatively significantly from a natural movement.
Weitere Finger-Bewegungsschienen bzw. Hand-Therapiegeräte sind aus der
Aus der
Zur Verbesserung dessen wurde in der
Bei allen derartigen Therapiegeräten muss vor Beginn des Trainings eine Anpassung des Geräts, insbesondere der einzelnen Finger-Bewegungsschienen, an die jeweilige Anatomie, also an die Handgröße und/oder die einzelnen Fingerabmessungen, durchgeführt werden. Dazu werden die einzelnen Finger-Bewegungsschienen zumeist manuell auf der Oberschale bzw. Halterung des jeweiligen Therapiegeräts in der für den jeweiligen Benutzer optimalen Position befestigt, die Finger-Bewegungsschienen müssen nach einer Trainingseinheit dann manuell gelöst und für den nächsten Benutzer an anderer Stelle wiederum manuell neu befestigt werden. Diese Prozedur ist zeitaufwendig und verkürzt im Klinikalltag nachteilig die für den jeweiligen Benutzer zur Verfügung stehende Trainingszeit mit dem Therapiegerät.For all such therapy devices, the device, in particular the individual finger movement splints, must be adjusted to the respective anatomy, i.e. to the hand size and/or the individual finger dimensions, before training begins. To do this, the individual finger movement splints are usually attached manually to the upper shell or holder of the respective therapy device in the optimal position for the respective user. The finger movement splints must then be manually removed after a training session and manually reattached in a different place for the next user. This procedure is time-consuming and, in everyday clinical practice, adversely reduces the training time available to the respective user with the therapy device.
Aufgabe der vorliegenden Erfindung ist es deshalb, eine Vorrichtung bzw. ein Verfahren bereitzustellen, welche die Anpassung einer Finger-Bewegungsschiene bzw. eines entsprechenden Therapiegeräts an die Anatomie des jeweiligen Benutzers schnell und kostengünstig automatisiert durchführt.The object of the present invention is therefore to provide a device or a method which carries out the adaptation of a finger movement splint or a corresponding therapy device to the anatomy of the respective user quickly and cost-effectively in an automated manner.
Diese Aufgabe wird durch eine Längeneinstellvorrichtung für eine FingerBewegungsschiene eines Therapiegeräts zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung eines Fingers und/oder eines Daumens einer Hand mit den Merkmalen des Patentanspruchs 1; durch eine Finger-Bewegungsschiene zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung eines Fingers und/oder eines Daumens einer Hand mit den Merkmalen des Patentanspruchs 11; durch ein Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung wenigstens eines Fingers und/oder eines Daumens einer Hand mit den Merkmalen des Patentanspruchs 12; sowie durch ein Verfahren zur Längeneinstellung einer Finger-Bewegungsschiene auf einem Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung wenigstens eines Fingers und/oder eines Daumens einer Hand mit den Merkmalen des Patentanspruchs 14 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen, welche jeweils einzeln oder in Kombination miteinander einsetzbar sind, sind Gegenstand der abhängigen Ansprüche.This object is achieved by a length adjustment device for a finger movement splint of a therapy device for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand with the features of patent claim 1; by a finger movement splint for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand with the features of patent claim 11; by a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or thumb of a hand with the features of patent claim 12; and by a method for adjusting the length of a finger movement rail on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or thumb of a hand with the features of patent claim 14. Advantageous embodiments and further developments, which can be used individually or in combination with one another, are the subject of the dependent claims.
Eine erfindungsgemäße Längeneinstellvorrichtung umfasst:
- wenigstens eine Einstellschiene;
- wenigstens ein, bezüglich der Einstellschiene bewegbares Haltemittel zur Halterung der Finger-Bewegungsschiene;
- wenigstens einen ersten, am Haltemittel angeordneten, Blockierungsmechanismus zur Blockierung der Bewegung des Haltemittels in eine erste Richtung entlang der Einstellschiene;
- wenigstens einen zweiten, am Haltemittel angeordneten, Blockierungsmechanismus zur Blockierung der Bewegung des Haltemittels in eine zweite Richtung entlang der Einstellschiene;
- wenigstens einen Schlitten,
- wobei der Schlitten über wenigstens ein Verbindungselement mit der Finger-Bewegungsschiene wirkverbindbar ist;
- wobei der Schlitten eingerichtet ist, mittels eines Antriebs zur Bewegung der Finger-Bewegungsschiene, entlang der Einstellschiene bewegt zu werden;
- wobei der Schlitten so ausgelegt ist, dass, wenn er mittels des Antriebs in die erste Richtung entlang der Einstellschiene bewegt wird, bei Kontakt mit dem ersten Blockierungsmechanismus eine Kraft auf den ersten Blockierungsmechanismus ausübt, sodass der erste Blockierungsmechanismus gelöst und das Haltemittel mitsamt der Finger-Bewegungsschiene durch Bewegung des Schlittens in die erste Richtung bewegbar ist;
- und wobei der Schlitten so ausgelegt ist, dass, wenn er mittels des Antriebs in die zweite Richtung entlang der Einstellschiene bewegt wird, bei Kontakt mit dem zweiten Blockierungsmechanismus eine Kraft auf den zweiten Blockierungsmechanismus ausübt, sodass der zweite Blockierungsmechanismus gelöst und das Haltemittel mitsamt der Finger-Bewegungsschiene durch Bewegung des Schlittens in die zweite Richtung bewegbar ist.
- at least one adjustment rail;
- at least one holding means movable relative to the adjustment rail for holding the finger movement rail;
- at least one first blocking mechanism arranged on the holding means for blocking the movement of the holding means in a first direction along the adjustment rail;
- at least one second blocking mechanism arranged on the holding means for blocking the movement of the holding means in a second direction along the adjustment rail;
- at least one sleigh,
- wherein the carriage is operatively connectable to the finger movement rail via at least one connecting element;
- wherein the carriage is adapted to be moved along the adjustment rail by means of a drive for moving the finger movement rail;
- wherein the carriage is designed such that when it is moved in the first direction along the adjustment rail by means of the drive, upon contact with the first blocking mechanism it exerts a force on the first blocking mechanism so that the first blocking mechanism is released and the holding means together with the finger movement rail can be moved in the first direction by moving the carriage;
- and wherein the carriage is designed such that when it is moved by means of the drive in the second direction along the adjustment rail, upon contact with the second blocking mechanism, a force is exerted on the second blocking mechanism so that the second blocking mechanism is released and the holding means together with the finger movement rail can be moved in the second direction by moving the carriage.
In einer ersten Ausgestaltung der Längeneinstellvorrichtung kann der Schlitten vorzugsweise unmittelbar mit dem Antrieb wirkverbindbar sein. In einer dazu alternativen, bevorzugten Ausgestaltung kann der Schlitten auch mittelbar über wenigstens ein Verbindungselement mit dem Antrieb wirkverbindbar sein. Eine Ausgestaltung bei der der Schlitten unmittelbar mit dem Antrieb wirkverbindbar ist, insbesondere über eine direkte Wirkverbindung zu einer Spindel des Antriebs, ermöglicht eine vergleichsweise einfache Konstruktion der Längeneinstellvorrichtung, wohingegen eine Ausgestaltung bei der der Schlitten mittelbar über wenigstens ein Verbindungselement mit dem Antrieb wirkverbindbar eine vergleichsweise kompakte, insbesondere flache Bauweise der Längeneinstellvorrichtung begünstigt.In a first embodiment of the length adjustment device, the carriage can preferably be operatively connected directly to the drive. In an alternative, preferred embodiment, the carriage can also be operatively connected indirectly to the drive via at least one connecting element. An embodiment in which the carriage can be operatively connected directly to the drive, in particular via a direct operative connection to a spindle of the drive, enables a comparatively simple construction of the length adjustment device, whereas an embodiment in which the carriage can be operatively connected indirectly to the drive via at least one connecting element promotes a comparatively compact, in particular flat construction of the length adjustment device.
In einer weiteren Ausgestaltung ist die Einstellschiene vorzugsweise eine Rasterbahn mit wenigsten zwei Rasterelementen. Eine Rasterbahn mit wenigstens zwei Rasterelementen ermöglicht vorteilhaft auf einfache Weise das Arretieren des Haltemittels und damit auch der Finger-Bewegungsschiene auf dem Therapiegerät.In a further embodiment, the adjustment rail is preferably a grid track with at least two grid elements. A grid track with at least two grid elements advantageously enables the holding means and thus also the finger movement rail to be locked onto the therapy device in a simple manner.
Dabei ist bevorzugt, dass die wenigstens zwei Rasterelemente im Wesentlichen keilförmig (dreieckig) und/oder halbkreisförmig und/oder in Form eines Kreisbogendreiecks (sog. "Reuleaux-Dreieck") aus der Ebene der Einstellschiene herausragen. Rasterelemente, die auf diese Weise aus der Ebene der Einstellbahn herausragen, ermöglichen vorteilhaft ein formschlüssiges Arretieren, wobei bei einer Keil (Dreicks-)form und/oder einer Halbkreisform und/oder der Form eines Kreisbogendreiecks (sog. "Reuleaux-Dreiecksform") die Wirkung des Blockierungsmechanismus durch Kraftausübung mittels des Schlittens einfacher (mit weniger Kraftaufwand) überwunden werden kann als es beispielsweise bei quaderförmig aus der Ebene herausragenden Rasterelementen der Fall wäre.It is preferred that the at least two grid elements protrude from the plane of the adjustment rail in a substantially wedge-shaped (triangular) and/or semicircular and/or in the form of a circular arc triangle (so-called "Reuleaux triangle"). Grid elements that protrude from the plane of the adjustment track in this way advantageously enable positive locking, whereby in the case of a wedge (triangular) shape and/or a semicircular shape and/or the shape of a circular arc triangle (so-called "Reuleaux triangle shape") the effect of the blocking mechanism can be overcome more easily (with less effort) by exerting force using the slide than would be the case, for example, with grid elements that protrude from the plane in a cuboid shape.
Alternativ dazu können die wenigstens zwei Rasterelemente auch als Löcher innerhalb der Einstellschiene ausgestaltet sein. Eine Einstellschiene mit Löchern als Rasterelementen im Sinne einer Lochplatte ermöglicht vorteilhaft eine flachere Bauweise der Einstellschiene.Alternatively, the at least two grid elements can also be designed as holes within the adjustment rail. An adjustment rail with holes as grid elements in the sense of a perforated plate advantageously enables a flatter construction of the adjustment rail.
In einer weiteren Ausgestaltung weist das Haltemittel vorzugsweise eine erste Seitenwand zur Halterung der Blockierungsmechanismen und eine zweite Seitenwand zur Halterung der Finger-Bewegungsschiene auf, welche wenigstens über ein Bodenelement miteinander verbunden sind, wodurch sich ein im Wesentlichen U-förmiger Querschnitt bildet, durch den die Einstellschiene verläuft. Ein im Wesentlichen U-förmig ausgestaltetes Haltemittel ermöglicht vorteilhaft eine einfache und kostengünstige Herstellung, je nach gewähltem Material zum Beispiel durch Biegen eines Metallblechs, durch Spritzguss oder 3D-Druck. Zudem lässt sich ein derartiges Haltemittel problemlos entlang der Einstellschiene als Führung verschieben.In a further embodiment, the holding means preferably has a first side wall for holding the blocking mechanisms and a second side wall for holding the finger movement rail, which are connected to one another at least via a base element, thereby forming a substantially U-shaped cross section through which the adjustment rail runs. A substantially U-shaped holding means advantageously enables simple and cost-effective production, depending on the material selected, for example by bending a metal sheet, by injection molding or 3D printing. In addition, such a holding means can easily be moved along the adjustment rail as a guide.
In einer alternativen Ausführungsform hat es sich bewährt, wenn die Einstellschiene entlang ihrer Längsachse eine erste Seitenwand und eine zweite Seitenwand umfasst, wobei die erste Seitenwand, die Einstellschiene und die zweite Seitenwand zusammen einen im Wesentlichen U-förmigen Querschnitt bilden, und wobei das Haltemittel innerhalb des im Wesentlichen U-förmigen Querschnitts bezüglich der Einstellschiene bewegbar angeordnet ist. Eine derartige Ausführung führt vorteilhaft zu einer besonders flachen Bauweise der Längeneinstellvorrichtung und somit zu geringem Platzbedarf auf innerhalb einer Finger-Bewegungsschiene bzw. auf einem Therapiegerät.In an alternative embodiment, it has proven useful if the adjustment rail comprises a first side wall and a second side wall along its longitudinal axis, wherein the first side wall, the adjustment rail and the second side wall together form a substantially U-shaped cross section, and wherein the holding means is arranged to be movable within the substantially U-shaped cross section with respect to the adjustment rail. Such an embodiment advantageously leads to a particularly flat design of the length adjustment device and thus to a small space requirement within a finger movement rail or on a therapy device.
Erfindungsgemäß bevorzugt ist darüber hinaus eine Ausgestaltung der Längeneinstellvorrichtung, bei der die Blockierungsmechanismen jeweils wenigstens ein am Haltemittel, vorzugsweise an der ersten Seitenwand, angeordnetes Fixiermittel; einen, über eine Drehachse drehbar am Haltemittel, vorzugsweise an der ersten Seitenwand, angelenkten Blockierungshebel; und ein Mittel zur Federung des Blockierungshebels gegenüber dem Fixiermittel umfassen, wobei der Blockierungshebel so ausgelegt ist, dass, wenn der Schlitten mit dem Blockierungshebel in Wirkverbindung tritt, der Blockierungshebel von einer Blockierungsposition in eine Deblockierungsposition gedreht wird und das Haltemittel dadurch in wenigstens eine Richtung bewegbar ist. Ein derartiger Blockierungsmechanismus ermöglicht vorteilhaft eine durch den Schlitten und damit den Antrieb der Finger-Bewegungsschiene bewirkte Positionsänderung des Haltemittels und der durch das Haltemittel gehaltenen Finger-Bewegungsschiene entlang der Einstellschiene auf dem Therapiegerät.According to the invention, a design of the length adjustment device is also preferred in which the blocking mechanisms each comprise at least one fixing means arranged on the holding means, preferably on the first side wall; a blocking lever pivoted on the holding means, preferably on the first side wall, via a rotation axis; and a means for springing the blocking lever relative to the fixing means, wherein the blocking lever is designed such that when the carriage comes into operative connection with the blocking lever, the blocking lever is rotated from a blocking position to an unblocking position and the holding means is thereby movable in at least one direction. Such a blocking mechanism advantageously enables a change in position of the holding means caused by the carriage and thus the drive of the finger movement rail and the the finger movement rail held by the holding device along the adjustment rail on the therapy device.
Alternativ dazu können die Blockierungsmechansimen auch einteilig ausgebildet und aus einem federnden Material, insbesondere Federstahl und/oder Hartgummi gebildet sein. Dabei können vorteilhaft die Fixiermittel und die Blockierungshebel aus einem einzigen Stück federndem Material gebildet werden, wobei die Blockierungshebel gegenüber den Fixiermitteln abgewinkelt angeordnet sein und die Schnittpunkte zwischen den Blockierungshebeln und den Fixiermitteln den Drehachsen entsprechen können. In dieser Ausgestaltungsform können die Mittel zur Federung durch die Federeigenschaften des federnden Materials, insbesondere des Federstahls und/oder des Hartgummis, selbst ersetzt werden, wodurch vorteilhaft jeweils ein Bauteil pro Blockierungsmechanismus eingespart und die Größe des Blockierungsmechanismus reduziert werden kann.Alternatively, the blocking mechanisms can also be designed as a single piece and made from a resilient material, in particular spring steel and/or hard rubber. The fixing means and the blocking levers can advantageously be made from a single piece of resilient material, with the blocking levers being arranged at an angle to the fixing means and the intersection points between the blocking levers and the fixing means corresponding to the axes of rotation. In this embodiment, the means for suspension can be replaced by the spring properties of the resilient material, in particular the spring steel and/or the hard rubber, itself, which advantageously saves one component per blocking mechanism and reduces the size of the blocking mechanism.
Zudem hat sich eine Ausgestaltung bewährt, bei der die Blockierungshebel in ihrer jeweiligen Blockierungsposition mit der Einstellschiene, insbesondere mit den Rasterelementen einer als Rasterbahn ausgebildeten Einstellschiene, in Wirkverbindung sind und in ihrer jeweiligen Deblockierungsposition mit der mit der Einstellschiene, insbesondere mit den Rasterelementen einer als Rasterbahn ausgebildeten Einstellschiene, nicht in Wirkverbindung sind. Wenn die Blockierungshebel mit der Einstellschiene, insbesondere mit den Rasterelementen einer als Rasterbahn ausgebildeten Einstellschiene, in Wirkverbindung sind, wird eine Verfahrbewegung des Haltemittels entlang der Einstellschiene vorteilhaft verhindert und die Fingerbewegungsschiene stabil und sicher an einer Position gehalten, so dass die Therapiebewegung sicher ausgeführt werden kann. Sind die Blockierungshebel nicht in Wirkverbindung mit der Einstellschiene, insbesondere mit den Rasterelementen einer als Rasterbahn ausgebildeten Einstellschiene; so kann das Haltemittel vorteilhaft entlang der Einstellschiene an eine beliebige Position oder, im Fall einer als Rasterbahn ausgebildeten Einstellschiene, an eine Position in Abhängigkeit der Rasterelemente oder der Löcher verfahren werden.In addition, a design has proven to be useful in which the blocking levers are operatively connected to the adjustment rail in their respective blocking position, in particular to the grid elements of an adjustment rail designed as a grid track, and in their respective unblocking position are not operatively connected to the adjustment rail, in particular to the grid elements of an adjustment rail designed as a grid track. If the blocking levers are operatively connected to the adjustment rail, in particular to the grid elements of an adjustment rail designed as a grid track, a movement of the holding means along the adjustment rail is advantageously prevented and the finger movement rail is held stable and securely in one position so that the therapy movement can be carried out safely. If the blocking levers are not operatively connected to the adjustment rail, in particular to the grid elements of an adjustment rail designed as a grid track, the holding means can advantageously be moved along the adjustment rail to any position or, in the case of an adjustment rail designed as a grid track, to a position depending on the grid elements or the holes.
Die vorliegende Erfindung betrifft auch eine Finger-Bewegungsschiene zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung eines Fingers und/oder eines Daumens einer Hand, umfassend eine Längeneinstellvorrichtung nach einem der Ansprüche 1 bis 10.The present invention also relates to a finger movement splint for performing a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand, comprising a length adjustment device according to one of claims 1 to 10.
Die vorliegende Erfindung betrifft zudem ein Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung wenigstens eines Fingers und/oder eines Daumens einer Hand, umfassend wenigstens einen Antrieb für eine Finger-Bewegungsschiene und wenigstens eine Finger-Bewegungsschiene nach Anspruch 11.The present invention also relates to a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, comprising at least one drive for a finger movement rail and at least one finger movement rail according to claim 11.
Dabei ist in einer Ausgestaltung des Therapiegeräts bevorzugt, dass der Antrieb ein linearer Antrieb, insbesondere ein Spindelmotor, ein Pneumatikzylinder, ein Hydraulikzylinder und/oder ein Seilzug, ist. Ein linearer Antrieb ermöglicht vorteilhaft eine kontrollierte Bewegung des Schlittens und damit sowohl der Finger-Bewegungsschiene während der Durchführung der Therapiebewegung als auch des Haltemittels nebst FingerBewegungsschiene während Längeneinstellung entlang der Einstellschiene.In one embodiment of the therapy device, it is preferred that the drive is a linear drive, in particular a spindle motor, a pneumatic cylinder, a hydraulic cylinder and/or a cable pull. A linear drive advantageously enables a controlled movement of the carriage and thus both the finger movement rail during the execution of the therapy movement and the holding means together with the finger movement rail during length adjustment along the adjustment rail.
Schließlich betrifft die vorliegende Erfindung ein Verfahren zur Längeneinstellung einer Finger-Bewegungsschiene auf einem Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung wenigstens eines Fingers und/oder eines Daumens einer Hand, welches sich dadurch auszeichnet, dass ein Verbindungselement einer, an einem Haltemittel angeordneten Finger-Bewegungsschiene mit Hilfe eines Antriebs über einen Schlitten entlang einer Einstellschiene aus einer Amplitude für eine Therapiebewegung in einen ersten oder zweiten Einstellbereich bewegt wird; wobei der Schlitten, wenn er mittels des Antriebs in eine erste Richtung entlang der Einstellschiene in den ersten Einstellbereich bewegt wird, bei Kontakt mit einem ersten Blockierungsmechanismus eine Kraft auf den ersten Blockierungsmechanismus ausübt, sodass der erste Blockierungsmechanismus gelöst und das Haltemittel mitsamt der FingerBewegungsschiene durch Bewegung des Schlittens in die erste Richtung bewegt wird und wobei der Schlitten, wenn er mittels des Antriebs in eine zweite Richtung entlang der Einstellschiene in den zweiten Einstellbereich bewegt wird, bei Kontakt mit einem zweiten Blockierungsmechanismus eine Kraft auf den zweiten Blockierungsmechanismus ausübt, sodass der zweite Blockierungsmechanismus gelöst und das Haltemittel mitsamt der Finger-Bewegungsschiene durch Bewegung des Schlittens in die zweite Richtung bewegt wird.Finally, the present invention relates to a method for adjusting the length of a finger movement rail on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, which is characterized in that a connecting element of a finger movement rail arranged on a holding means is moved with the aid of a drive via a carriage along an adjustment rail from an amplitude for a therapy movement into a first or second adjustment range; wherein the carriage, when moved by means of the drive in a first direction along the adjustment rail into the first adjustment range, exerts a force on the first blocking mechanism upon contact with a first blocking mechanism, so that the first blocking mechanism is released and the holding means together with the finger movement rail is moved by movement of the carriage in the first direction, and wherein the carriage, when moved by means of the drive in a second direction along the adjustment rail into the second adjustment range, exerts a force on the second blocking mechanism upon contact with a second blocking mechanism, so that the second blocking mechanism is released and the holding means together with the finger movement rail is moved by movement of the carriage in the second direction.
Eine erfindungsgemäße Längeneinstellvorrichtung bzw. ein erfindungsgemäßes Verfahren zur Längeneinstellung ermöglicht es vorteilhaft, eine Finger-Bewegungsschiene mit Hilfe des für die Finger-Bewegungsschiene auf einem Therapiegerät bereits vorhandenen Antriebs entlang einer Einstellschiene automatisch zu verschieben und an einer gewünschten Position - in Abhängigkeit der Fingerlänge bzw. Handgröße/länge des Benutzers - auf der Einstellschiene und damit auf dem Therapiegerät zu fixieren, um dann in einer stabilen Position eine kontinuierliche, passive und/oder aktiv-assistierte Bewegung eines Fingers und/oder eines Daumens einer Hand durchführen zu können. Ein zeitaufwendiges manuelles Einstellen ist dadurch vorteilhaft vermieden.A length adjustment device according to the invention or a method according to the invention for length adjustment advantageously makes it possible to automatically move a finger movement rail along an adjustment rail using the drive already present for the finger movement rail on a therapy device and to fix it in a desired position - depending on the finger length or hand size/length of the user - on the adjustment rail and thus on the therapy device in order to then be able to carry out a continuous, passive and/or actively assisted movement of a finger and/or thumb of a hand in a stable position. Time-consuming manual adjustment is thus advantageously avoided.

Darüber hinaus umfasst die erfindungsgemäße Längeneinstellvorrichtung 3 wenigstens einen Schlitten 33, wobei der Schlitten 33 über wenigstens ein Verbindungselement 20a bzw. 20b (vgl.
Die
Zum Bewegen des Haltemittels 34 entlang der Einstellschiene 30 von einer auf der Einstellschiene 30 fixierten Betriebsposition zu einer anderen und damit zur Längeneinstellung der Finger-Bewegungsschiene 2 wird ein Verbindungselement 20a bzw. 20b (vgl.
Entsprechend gilt für die Bewegung in eine entgegengesetzte zweite Richtung B2: Der Schlitten 30 einer erfindungsgemäßen Längeneinstellvorrichtung 3 ist so ausgelegt, dass, wenn er mittels des Antriebs 10, insbesondere mittels der durch den Motor 101 des Antriebs 10 angetriebenen Spindel 102; in die zweite Richtung B2 entlang der Einstellschiene 30 bewegt wird, bei Kontakt mit dem zweiten Blockierungsmechanismus 32 eine Kraft auf den zweiten Blockierungsmechanismus 32 ausübt, sodass der zweite Blockierungsmechanismus 32 gelöst und das Haltemittel 34 mitsamt der Finger-Bewegungsschiene 2 durch Bewegung des Schlittens 30 in die zweite Richtung B2 bewegbar ist. In diesem Fall übt der Schlitten 30, wenn er mittels des Antriebs 10 in eine zweite Richtung B2 entlang der Einstellschiene 30 in den zweiten Einstellbereich A3 bewegt wird, bei Kontakt mit einem zweiten Blockierungsmechanismus 32 eine Kraft auf den zweiten Blockierungsmechanismus 32 aus, sodass der zweite Blockierungsmechanismus 32 gelöst und das Haltemittel 34 mitsamt der Finger-Bewegungsschiene 2 durch Bewegung des Schlittens 33 in die zweite Richtung B2 bewegt wird. Die Kraftausübung kann auch hier wieder über den Gleitfuß 331 erfolgen. Der Blockierungshebel 312 des ersten Blockierungsmechanismus 31 blockiert die Bewegung des Haltemittels 34 in die zweite Richtung B2 nicht, sondern lässt sich einfach durch das vom Schlitten 33 bewegte Haltemittel 34 mitziehen.The following applies accordingly to the movement in an opposite second direction B2: The
Die Einstellschiene 30 kann insbesondere eine Rasterbahn mit wenigstens zwei Rasterelementen 301 sein. Dabei können die wenigstens zwei Rasterelemente 301 als im Wesentlichen keilförmig (dreieckig) - wie insbesondere in den
