Description

Trainingsgerät zur Verbesserung von Kraft, Beweglichkeit, Ausdauer und Ansteue- rung an verschiedenen Gelenken und deren umgebende Weichteilstrukturen  Training device for improving strength, flexibility, endurance and control of various joints and their surrounding soft tissue structures
Die Erfindung betrifft ein Trainingsgerät zur Verbesserung von Kraft, Beweglichkeit, Ausdauer und Ansteuerung an verschiedenen Gelenken und deren umgebenden Weichteilmantel an den Extremitäten. Es kann sowohl als allgemeines Trainingsgerät als auch speziell prä- oder postoperativ eingesetzt werden. Gerade im Bereich der Knie- Hüft- und Schulterrehabilitation ist die direkt postoperative Anwendbarkeit ein wesentliches Merkmal des Trainingsgerätes. The invention relates to a training device for improving strength, flexibility, endurance and control at various joints and their surrounding soft tissue jacket on the extremities. It can be used both as a general training device and especially pre- or postoperatively. Particularly in the field of knee hip and shoulder rehabilitation, direct postoperative applicability is an essential feature of the training device.
Operationen am Kniegelenk gehören zu den häufigsten Operationen in der Orthopädie und Unfallchirurgie. Postoperativ sind dabei die möglichst schnelle Wiederherstellung der Streckfähigkeit im Kniegelenk sowie die Verbesserung von Muskelkraft und Ansteuerung des Streckapparates von herausragender Bedeutung. Ähnli- ches gilt auch für Operationen an Schulter- , Hüft- oder anderen Gelenken. Während an der Schulter die schnelle Verbesserung der Beweglichkeit zur Verhinderung einer Einsteifung wesentlich ist, steht gerade nach erfolgter Prothesenversorgung an der Hüfte das schnelle Erlangen von Kraft und Ansteuerungsfähigkeit zum schnellen Erlernen eines sicheren Gangbildes im Zentrum der Frührehabilitation. Gleichzeitig kann das Trainingsgerät auch als ein wesentlicher Bestandteil der nicht medikamentösen Thromboseprophylaxe angesehen und genutzt werden. Operations on the knee joint are among the most common operations in orthopedics and traumatology. Postoperatively, the fastest possible restoration of distensibility in the knee joint as well as the improvement of muscle strength and control of the extensor apparatus are of paramount importance. The same applies to surgery on shoulder, hip or other joints. While the rapid improvement of mobility to prevent stiffening is essential at the shoulder, just after prosthetic hip replacement, the rapid attainment of power and responsiveness for quickly learning a safe gait is at the heart of early rehabilitation. At the same time, the training device can also be regarded and used as an essential component of non-drug thrombosis prophylaxis.
In älteren Behandlungskonzepten wurde in der direkt postoperativen Phase bei einem Kniegelenk mit Schmerzkathetern gearbeitet, die das Bein betäuben, um dem Patienten den Schmerz zu nehmen. Patienten mit Schmerzkathetern dürfen jedoch nicht aufstehen, da das Sturzrisiko bei teilbetäubtem Bein sehr hoch ist. Dies hatte zur Folge, dass Patienten oftmals mehrere Tage bettlägerig waren und außerdem Angst vor Schmerzen entwickelten, so dass der Heilungsprozess erheblich verzögert wurde. Der Einsatz von Bewegungsschienen, mit denen das Bein oder in anderen Fällen auch der Arm bzw. das Schultergelenk passiv bewegt wird, ohne dass der Patient mitarbeitet, führt im Allgemeinen nicht dazu, dass der Heilungsprozess wesentlich beschleunigt wird. Aus diesem Grund wird angestrebt, einen Patienten möglichst frühzeitig dazu zu motivieren, selbst aktiv tätig zu werden und damit seinen Heilungsprozess selbst aktiv zu fördern. In older treatment concepts, in the postoperative period, a knee joint with pain catheters was used, which numbed the leg to relieve the patient's pain. Patients with pain catheters, however, should not get up because the risk of falls in partially stunned leg is very high. As a result, patients were often bedridden for several days and also developed anxiety about pain, significantly delaying the healing process. The use of motion rails, with which the leg or in other cases, the arm or the shoulder joint is moved passively, without the Patient co-operation, generally does not cause the healing process is significantly accelerated. For this reason, it is endeavored to motivate a patient as early as possible to become actively involved and thus to actively promote his own healing process.
Dieser auch als Frührehabilitation bezeichnete Behandlungsansatz wird bereits in der Visceralchirurgie unter dem Begriff "Fast-Track" zunehmend umgesetzt. Auch in der Orthopädie und Unfallchirurgie gibt es verschiedene Ansätze zur schnelleren Mobilisierung insbesondere nach einer Hüft- oder Kniearthroplastie, aber auch nach Kreuzbandoperationen und im Bereich des wachsenden Sektors der ambulant durchgeführten Operationen. This treatment approach, also known as early rehabilitation, is already being increasingly implemented in visceral surgery under the term "fast track". In orthopedics and trauma surgery, too, there are various approaches for faster mobilization, in particular after hip or knee arthroplasty, but also after cruciate ligament surgery and in the growing sector of outpatient surgery.
Ein Ziel besteht darin, eine Anpassung an die, wie sich gezeigt hat, inter- und intraindividuell sehr unterschiedlichen Bewegungseinschränkungen der Patienten oder deren individuelle Konstitution zu ermöglichen. Außerdem ist es wünschenswert, eine große Anzahl von reproduzierbaren Messungen durchzuführen und auszuwerten oder dem Patienten individuell abgestimmte Kraftprofile vorzugeben. Die Möglichkeit einer automatischen Datenspeicherung und die Anpassung von Trainingsund Rena-Programmen an die individuell gewonnenen Ergebnisse wäre ebenfalls vorteilhaft. One goal is to adapt to the, as has been shown, very different patient movement restrictions or their individual constitution between individuals and individuals. In addition, it is desirable to perform and evaluate a large number of reproducible measurements or to provide the patient with individually tailored force profiles. The possibility of automatic data storage and the adaptation of training and Rena programs to individually obtained results would also be beneficial.
Ausgehend von den oben dargestellten Erkenntnissen und Zielsetzungen liegt der Erfindung die Aufgabe zugrunde, ein Trainingsgerät der eingangs genannten Art zu schaffen, mit dem eine schnellere, insbesondere postoperative Verbesserung der Kraft und Ansteuerung insbesondere im Knie- oder Schultergelenk und somit eine schnellere Mobilisierung erzielt werden kann. Gleichzeitig soll die Compliance des Patienten verbessert und so der Patient für eine aktive Beeinflussung seines Rehabilitationsergebnisses motiviert werden. Gelöst wird diese Aufgabe mit einem Trainingsgerät gemäß Anspruch 1. Die abhängigen Ansprüche haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt. Besondere Vorteile dieser Lösung bestehen darin, dass das erfindungsgemäße Trainingsgerät schon in einer sehr frühen Phase unmittelbar nach einer Operation insbesondere am Schulter- oder Knie- bzw. Hüftgelenk eingesetzt werden kann, wenn noch nicht so hohe Kräfte ausgeübt werden können. Das erfindungsgemäße Trainingsgerät ermöglicht auch ein problemloses selbstständiges Training. Dies hat auch zur Folge, dass die Motivation des Patienten zur aktiven Mitwirkung sowie seine Bereitschaft, in einer frühen Phase nach einer Operation Eigenverantwortung für den Genesungsprozess zu übernehmen, erheblich gesteigert wird. Based on the findings and objectives set out above, the invention has for its object to provide a training device of the type mentioned, with a faster, especially postoperative improvement of the force and control especially in the knee or shoulder joint and thus a faster mobilization can be achieved , At the same time, the patient's compliance is to be improved, thus motivating the patient to actively influence his rehabilitation outcome. This object is achieved with a training device according to claim 1. The dependent claims have advantageous developments of the invention to the content. Particular advantages of this solution are that the training device according to the invention can be used at a very early stage immediately after surgery especially on the shoulder or knee or hip joint, if not so high forces can be exercised. The training device according to the invention also allows trouble-free independent training. This also means that the motivation of the patient to participate actively as well as his willingness to assume responsibility for the recovery process in an early phase after an operation is considerably increased.
Weiterhin kann das erfindungsgemäße Trainingsgerät auch an anderen Gelenken wie zum Beispiel am Sprunggelenk und bei weiteren Indikationen wie zum Beispiel konservativen Therapien, Präventionen, allgemeinem Training oder als Thromboseprophylaxe sowie als Diagnostikum zum Erreichen bestimmter Rehabilitationsziele angewendet werden. Weitere Vorteile der Erfindung bestehen darin, dass durch die Anwendung von Druck- bzw. Zugkraftsensoren in verschiedenen Ausgestaltungen eine relativ genaue Kraftmessung möglich ist, die in Echtzeit visualisiert und gespeichert werden kann und damit dem Patienten eine unmittelbare Rückkopplung gibt. Das Trainingsgerät umfasst zu diesem Zweck vorzugsweise eine elektronische Schaltungsanordnung, mit der die von den Druck- oder Zugkraftsensoren erzeugten Messsignale aufbereitet und drahtlos oder drahtgebunden an eine entfernte Empfangsstation insbesondere zur Visualisierung und/oder Speicherung übertragen werden. Weiterhin kann dem Patienten ein bestimmtes gespeichertes Kraftprofil als Soll- Kurve vorgegeben und zum Beispiel auf einem Display angezeigt und die Soll-Kurve dann zur Analyse und Auswertung mit einer erzielten Ist-Kurve verglichen werden. Dies kann durch die Verwendung von verschiedenen Apps, die für diese Geräte entwickelt wurden, auch auf spielerische Art im Sinne einfacher Computerspiele dargestellt werden. Dabei ist es auch möglich, das Profil einer vorgegebenen Kraft- Sollkurve an einen bestimmten Ist-Zustand eines Patienten bzw. dessen aktuelle Leistungsfähigkeit automatisch anzupassen. Die tatsächlich erzielte Ist-Kurve des Kraftverlaufes kann ebenfalls gespeichert und zur Fortschrittsanalyse mit später erzielten weiteren solchen Ist-Kurven verglichen werden. Patient und Therapeut haben über die automatisch gespeicherten Daten und Kurven genaue Informationen über die tatsächlich durchgeführten Trainingseinheiten, die erzielten Kraftwerte und Abweichungen von einer vorgegebenen Ist-Kurve und über den individuellen Trainingsfortschritt. Schließlich lässt sich im Therapeutenmodus vorzugsweise vor- konfigurieren, ob beide Knie- bzw. Hüft- oder Schultergelenke oder nur die rechte oder die linke Seite trainiert werden sollen. Furthermore, the exercise device according to the invention can also be applied to other joints such as ankle and other indications such as conservative therapies, prevention, general training or thrombosis prophylaxis and as a diagnostic tool to achieve certain rehabilitation goals. Further advantages of the invention are that a relatively accurate force measurement is possible by the use of pressure or tension sensors in various configurations, which can be visualized and stored in real time and thus gives the patient an immediate feedback. The training device for this purpose preferably comprises an electronic circuit arrangement with which the measurement signals generated by the pressure or tension sensors are processed and transmitted wirelessly or by wire to a remote receiving station, in particular for visualization and / or storage. Furthermore, the patient can be given a specific stored force profile as the setpoint curve and displayed, for example, on a display, and the setpoint curve can then be compared with an actual curve obtained for analysis and evaluation. This can also be represented in a playful way in the sense of simple computer games by using different apps developed for these devices. It is also possible to automatically adjust the profile of a predetermined force-target curve to a specific actual state of a patient or his current performance. The actually obtained actual curve of the force curve can also be stored and compared to the progress analysis with other such actual curves obtained later. The patient and the therapist have detailed information about the actually performed training units, the achieved force values and deviations from a given actual curve and about the individual training progress via the automatically stored data and curves. Finally, in the therapist mode, it is preferably possible to pre-configure whether both knee, hip, or shoulder joints or only the right or the left side should be trained.
Trotz all dieser Vorteile ist das Trainingsgerät relativ einfach aufgebaut, transportabel und kostengünstig herstellbar. Despite all these advantages, the training device is relatively simple, portable and inexpensive to produce.

A targeted back training with forms of movement in the different axes of movement is easily feasible.
In den Figuren 1 und 2 sind verschiedene Anwendungen eines solchen Trainingsgerätes 10 dargestellt. FIGS. 1 and 2 show various applications of such a training device 10.
Es umfasst im Wesentlichen ein zylindrisches Gehäuse, an dessen beiden axialseiti- gen Enden zum Beispiel Schlaufen 11, 12 befestigt sind, mit denen es zum einen an einem Türgriff oder an einer Wand ortsfest fixiert und zum anderen mit einer Hand oder einem Bein bzw. Unterschenkel eines Patienten gehalten werden kann. Durch Ziehen können dann die Arm- und Schulter- bzw. Bein- und Hüftmuskulatur bzw. die betreffenden Gelenke trainiert werden. It essentially comprises a cylindrical housing, at the two axialseiti- gene ends, for example, loops 11, 12 are fixed, with which it fixed on the one hand to a door handle or on a wall stationary and the other with a hand or leg or lower leg a patient can be held. By pulling then the arm and shoulder or leg and hip muscles or the joints in question can be trained.
Das Gehäuse ist zu diesem Zweck entweder aus einem insbesondere in axialer Richtung flexiblen, dehnbaren Material wie zum Beispiel Gummi oder Hartgummi gebildet und zum Beispiel auf seiner Oberfläche mit Dehnungsmessstreifen versehen, oder es beinhaltet entsprechende Federanordnungen mit Zugkraft- Messeinrichtungen wie zum Beispiel in Form von Zug- oder Druckkraftsensoren. The housing is formed for this purpose either from a particularly flexible in the axial direction, stretchable material such as rubber or hard rubber and provided, for example on its surface with strain gauges, or it includes corresponding spring arrangements with Zugkraft- measuring devices such as in the form of train - or pressure force sensors.
Figur 3 zeigt schematisch einen beispielhaften allgemeinen Aufbau eines erfindungsgemäßen Trainingsgerätes 10. An den beiden Stirn- bzw. axialseitigen Enden des Trainingsgerätes 10 bzw. von dessen Gehäuse ist jeweils eine erste bzw. eine zweite Befestigungseinrichtung 13, 14 zum Beispiel in Form eines Hakens oder einer Öse angeordnet, die zum Beispiel mittels jeweils einer Metallplatte 131, 141 an dem Gehäuse montiert sind und an denen die Schlaufen 11 bzw. 12 befestigt werden. Das Gehäuse ist im dargestellten Fall zylindrisch und hat einen kreisförmigen Querschnitt, es könnte jedoch auch ei- nen anderen Querschnitt einschließlich eines rechteckigen bzw. quadratischen Querschnitts aufweisen. Figure 3 shows schematically an exemplary general structure of a training device according to the invention 10. At the two end or axial ends of the training device 10 and its housing is respectively a first and a second fastening means 13, 14, for example in the form of a hook or a Eyelet arranged, for example, by means of a respective metal plate 131, 141 are mounted on the housing and to which the loops 11 and 12 are attached. The housing is cylindrical in the illustrated case and has a circular cross-section, but it could also be a NEN another cross section including a rectangular or square cross-section.
Durch die in den Figuren 1 und 2 gezeigte Anwendung des Trainingsgerätes werden auf dieses Zugkräfte in Richtung von dessen Längsachse ausgeübt. Um diese Zugkräfte zu messen, weist das Trainingsgerät einen oder mehrere Zug- oder Druckkraftsensoren auf, die, je nach Ausgestaltung des Trainingsgerätes, zum Beispiel in Form von Dehnungsmessstreifen oder anderen Zug- oder Druckkraftsensoren ausgebildet sein können. By the application of the training device shown in Figures 1 and 2 are applied to this tensile forces in the direction of its longitudinal axis. In order to measure these tractive forces, the training device has one or more tension or compression force sensors, which, depending on the design of the training device, can be designed, for example, in the form of strain gauges or other tension or compression force sensors.
Wenn das Trainingsgerät oder dessen Gehäuse aus einem durch die genannten Zugkräfte dehnbaren Material gefertigt ist oder ein solches Material aufweist, so können Dehnungsmessstreifen auch in allgemein bekannter Weise auf dieses Material aufgebracht werden, um Längenänderungen durch die einwirkenden Zugkräfte zu erfassen. If the training device or its housing is made of a stretchable by said tensile forces material or has such a material, then strain gauges can also be applied in a well known manner to this material to detect changes in length by the applied tensile forces.
Andererseits besteht auch die Möglichkeit, die an den beiden axialen Enden bzw. den Befestigungseinrichtungen 13, 14 angreifenden Zugkräfte über innerhalb des Trainingsgerät 10 befindliche und mit ihren Ende jeweils an den Metallplatten 131, 141 befestigte Stangen 15, 16 auf entsprechende Schraubenfedern, Tellerfedern, Evolutfedern oder andere Federanordnungen mit entsprechenden Zugkraft- Messeinrichtungen 17 (nur schematisch angedeutet) innerhalb des Gehäuses zu leiten, um deren Dehnung bzw. Streckung wiederum mittel Dehnungsmessstreifen oder anderer Kraftsensoren zu erfassen. On the other hand, there is also the possibility of the tensile forces acting on the two axial ends or the fastening devices 13, 14 via rods 15, 16 fastened within the training apparatus 10 and fastened at their ends to the metal plates 131, 141, respectively, to corresponding coil springs, cup springs, evolution springs or other spring assemblies with corresponding Zugkraft- measuring devices 17 (only schematically indicated) to be directed within the housing to detect their strain or strain again medium strain gauges or other force sensors.
In dem Gehäuse befindet sich auch die oben genannte elektronische Schaltungsanordnung (nicht dargestellt), mit der die genannten Dehnungsmessstreifen oder anderen Kraftsensoren verbunden sind und mit der die erzeugten Kraftsensor- bzw. Messsignale aufbereitet und zur Auswertung vorzugsweise drahtlos oder drahtge- bunden an eine entfernte Empfangsstation übertragen werden. Figur 4(A) zeigt eine schematische Querschnittsansicht (Prinzipdarstellung) wesentlicher Komponenten einer ersten Ausführungsform des Trainingsgerätes. Das Trainingsgerät weist an seinen beiden Stirn- bzw. axialseitigen Enden wiederum (wie es oben beschrieben wurde) eine erste bzw. eine zweite Befestigungseinrichtung 13, 14 (Haken oder Öse etc.) auf. Es beinhaltet die genannte Schaltungsplatine P mit der elektronischen Schaltungsanordnung, mittels der die von einem Kraftsensor Dl erfassten Signale vorzugsweise drahtlos oder drahtgebunden zu einer Emp- fangs- und Auswertestation übertragen werden, sowie mindestens ein Batteriefach B mit Batterie oder Akku (der zum Beispiel über einen Mini-USB-Anschluss aufladbar ist) oder auch eine oder mehrere Fotozellen an einer Außenseite des Trainingsgerätes zur Spannungsversorgung der Schaltungsplatine P. Der Kraftsensor Dl zur Erfassung der auf das Trainingsgerät durch einen Patienten ausgeübten Zugkraft Fz ist in diesem Fall durch einen Druckkraftsensor wie zum Beispiel eine Druckmessfolie Dl gebildet, auf die ein erster Hebelarm Hl eines Hebels einwirkt. Der zweite Hebelarm H2 des Hebels ist mit der zweiten Befestigungseinrichtung 14 verbunden. Die Hebelarme Hl, H2 sind im Wesentlichen rechtwinklig miteinander verbunden und vorzugsweise an ihrer Verbindungsstelle um eine Drehachse HR schwenkbar an dem Trainingsgerät gelagert, so dass gemäß der Darstellung der Kraftverläufe in Figur 4(B) durch eine Zugkraft Fz, die im Wesentlichen in senkrechter Richtung zu dem zweiten Hebelarm H2 an diesem angreift, mittels des ersten Hebelarms Hl eine entsprechende Kraft FR in zu diesem senkrechter Rich- tung auf die Druckmessfolie Dl ausgeübt wird. The housing also contains the abovementioned electronic circuit arrangement (not shown), with which the strain gauges or other force sensors are connected and with which the generated force sensor or measuring signals are processed and, preferably for evaluation, wirelessly or wired to a remote receiving station be transmitted. Figure 4 (A) shows a schematic cross-sectional view (schematic diagram) of essential components of a first embodiment of the training device. The training device has at its two end or axial ends again (as described above) a first and a second fastening means 13, 14 (hook or eye etc.). It contains the aforementioned circuit board P with the electronic circuit arrangement, by means of which the signals detected by a force sensor D1 are preferably transmitted wirelessly or by wire to a receiving and evaluating station, and at least one battery compartment B with battery or rechargeable battery (for example via a Miniature USB port is rechargeable) or one or more photocells on an outside of the training device for powering the circuit board P. The force sensor Dl for detecting the force exerted on the exerciser by a patient tensile force F z is in this case by a pressure force sensor such Example, a pressure measuring film Dl formed, acts on a first lever arm Hl of a lever. The second lever arm H2 of the lever is connected to the second fastening device 14. The lever arms Hl, H2 are connected substantially at right angles to one another and are preferably pivotably mounted on the training device at their connection point about an axis of rotation H R , so that according to the representation of the force profiles in FIG. 4 (B) by a tensile force F z , which is substantially in perpendicular to the second lever arm H2 acts on this, by means of the first lever arm Hl a corresponding force F R is exerted in this direction perpendicular to the pressure measuring film Dl.
Somit werden also bei dieser ersten Ausführungsform die von einem Patienten ausgeübten Zugkräfte Fz mittels eines Druckkraftsensors Dl erfasst. Die Figuren 5 und 6 zeigen schematisch aus verschiedenen Blickwinkeln eine dreidimensionale erste bzw. zweite Ansicht dieser ersten Ausführungsform eines erfindungsgemäßen Trainingsgerätes. Die Darstellungen zeigen wiederum die erste Befestigungseinrichtung 13, die in diesem Fall beispielhaft zwei Klemmbacken aufweist, mittels derer das Trainingsgerät zum Beispiel an einem Türreck oder einer anderen Stange 132 festgeklemmt werden kann, sowie die zweite Befestigungseinrichtung 14 für eine Schlaufe 12, mit der ein Patient die genannten Zugkräfte Fz auf das Trainingsgerät ausübt. Thus, in this first embodiment, the tensile forces F z exerted by a patient are detected by means of a pressure force sensor D 1. Figures 5 and 6 show schematically from different angles a three-dimensional first or second view of this first embodiment of a training device according to the invention. The illustrations again show the first fastening device 13, which in this case has, for example, two clamping jaws, by means of which the training device can be clamped, for example, to a door rail or another rod 132, and the second fastening device 14 for a loop 12, with which a patient the said tensile forces F z exerted on the exercise device.
Weiterhin ist eine erste und eine zweite Halteeinrichtung 102, 103 vorgesehen, die entlang der Längsachse des Trainingsgerätes, entlang der auch die auf dieses ausgeübten Zugkräfte Fz wirken, beabstandet sind. An bzw. zwischen diesen beiden Halteeinrichtungen 102, 103 sind der Hebel mit dem ersten Hebelarm Hl (der zwei- te Hebelarm H2 ist in diesen Darstellungen nicht erkennbar), sowie vorzugsweise mindestens ein erstes Batteriefach Bl, die Schaltungsplatine P, sowie mindestens eine erste obere Strebe 105 und mindestens eine erste untere Strebe 107 angeordnet bzw. befestigt. Die zweite Halteeinrichtung 103 weist eine Bohrung 103a für einen Stift 103c (siehe Figuren 7 und 8) auf, mit dem der Hebel um seine Drehachse HR schwenkbar an der zweiten Halteeinrichtung 103 gelagert ist. Schließlich befindet sich an der in Axialrichtung äußeren Stirnfläche der zweiten Halteeinrichtung 103 vorzugsweise noch ein Abschlussdeckel 104. Furthermore, a first and a second holding device 102, 103 are provided, which are along the longitudinal axis of the training device, along which also act on the applied tensile forces F z , spaced. At or between these two holding devices 102, 103, the lever with the first lever arm Hl (the second lever arm H2 is not recognizable in these illustrations), and preferably at least a first battery compartment Bl, the circuit board P, and at least one first upper Strut 105 and at least a first lower strut 107 arranged or attached. The second holding device 103 has a hole 103a for a pin 103c (see FIGS. 7 and 8), with which the lever is mounted pivotably on the second holding device 103 about its axis of rotation H R. Finally, at the axially outer end face of the second holding device 103 is preferably still a cover cover 104th

Zusätzlich zu den in den Figuren 5 und 6 gezeigten Komponenten sind in diesen Ansichten auch der zweite Hebelarm H2 des Hebels, ein zweites Batteriefach B2, sowie eine zweite obere Strebe 106 und eine zweite untere Strebe 108 dargestellt. Ferner ist zu erkennen, dass sich an dem freien Ende des ersten Hebelarms Hl ein Vorsprung 109 befindet, über den der erste Hebelarm Hl auf den Druckkraftsensor Dl drückt. Dieser Druckkraftsensor Dl ruht auf einer entsprechenden Auflage in der ersten Halteeinrichtung 102 und ist elektrisch mit der Schaltungsplatine P verbun- den. In addition to the components shown in FIGS. 5 and 6, these views also show the second lever arm H2 of the lever, a second battery compartment B2, as well as a second upper strut 106 and a second lower strut 108. Furthermore, it can be seen that at the free end of the first lever arm Hl is a projection 109, via which the first lever arm Hl presses on the pressure force sensor Dl. This pressure force sensor Dl rests on a corresponding support in the first holding device 102 and is electrically connected to the circuit board P.
Weiterhin ist zu erkennen, dass die zweite Halteeinrichtung 103 neben der bereits genannten Bohrung 103a für den Stift 103c eine Ausnehmung 103b aufweist, die so bemessen ist, dass der zweite Hebelarm H2 darin Platz findet, wenn dieser mittels des Stiftes 103c an der zweiten Halteeinrichtung 103 schwenkbar gelagert ist. Furthermore, it can be seen that the second holding device 103 in addition to the already mentioned hole 103a for the pin 103c has a recess 103b which is dimensioned so that the second lever arm H2 fits into it, if this by means of the pin 103c on the second holding device 103rd is pivotally mounted.
Die zweite Befestigungseinrichtung 14 ist an dem zweiten Hebelarm H2 fixiert, um die von einem Patienten ausgeübter Zugkraft Fz auf diesen zu übertragen. Zu diesem Zweck weist der zweite Hebelarm H2 zum Beispiel eine Gewindebohrung 143 auf, in die ein entsprechender Gewindeabschnitt 142 an der zweiten Befestigungseinrichtung 14 eingedreht wird. The second fastening device 14 is fixed to the second lever arm H2 in order to transmit the tensile force F z exerted by a patient to it. For this purpose, the second lever arm H2, for example, a threaded bore 143 into which a corresponding threaded portion 142 is screwed to the second fastening device 14.
Außerdem ist in diesen Figuren auch schematisch ein Tastschalter T an der zweiten Halteeinrichtung 103 bzw. dem Abschlussdeckel 104 angedeutet, der mit der Schal- tungsplatine verbunden ist und zum Beispiel zum Ein- und Ausschalten der Übertragung der Sensorsignale dient. Weiterhin können dort auch eine oder mehrere LEDs zur Signalisierung von Betriebszuständen der Schaltungsplatine P bzw. der darauf aufgebrachten Schaltungsanordnung angebracht sein. Die beiden Halteeinrichtungen 102, 103 sind mittels der vorzugsweise vier Streben 105, 106, 107, 108 in Axialrichtung des Trainingsgerätes voneinander beabstandet und mechanisch fest miteinander verbunden. Die Länge, Anzahl und Anordnung der Streben 105, 106, 107, 108 ist entsprechend der Länge des ersten Hebelarms Hl sowie des für das mindestens eine Batteriefach Bl, B2 und die Schaltungsplatine P erforderlichen Platzes geeignet bemessen. Die Schaltungsplatine P und/oder das mindestens eine Batteriefach Bl, B2 kann dabei an den Streben und/oder zumindest an einer der beiden Halteeinrichtungen 102, 103 mittels üblicher Montagemittel befestigt sein. Auch die Befestigung des Abschlussdeckels 104 an der zweiten Halteeinrichtung 103, des Tastschalters T sowie die Führung des Gewindeabschnitts 142 durch den Abschlussdeckel 104 zu der Gewindebohrung 143 erfolgt mittels bekannter Montagemittel (wie insbesondere Schrauben, Muttern, Buchsen, Unterleg- und Federscheiben etc.) in fachüblicher Weise. In addition, these figures also schematically indicate a push-button switch T on the second holding device 103 or on the end cover 104, which is connected to the circuit board and serves, for example, for switching on and off the transmission of the sensor signals. Furthermore, one or more LEDs for signaling operating states of the circuit board P or the circuit arrangement applied thereto can also be mounted there. The two holding devices 102, 103 are spaced apart from each other by means of the preferably four struts 105, 106, 107, 108 in the axial direction of the training device and mechanically connected to one another. The length, number and arrangement of the struts 105, 106, 107, 108 is suitably dimensioned according to the length of the first lever arm Hl and the space required for the at least one battery compartment Bl, B2 and the circuit board P. The circuit board P and / or the At least one battery compartment Bl, B2 can be attached to the struts and / or at least one of the two holding devices 102, 103 by means of conventional mounting means.

Figur 9(A) zeigt eine schematische Querschnittsansicht (Prinzipdarstellung) wesentlicher Komponenten einer zweiten Ausführungsform des Trainingsgerätes. Gleiche oder einander entsprechende Teile wie insbesondere in Figur 4 sind mit gleichen bzw. entsprechenden Bezugsziffern versehen. FIG. 9 (A) shows a schematic cross-sectional view (schematic illustration) of essential components of a second embodiment of the training device. The same or corresponding parts as in particular in Figure 4 are provided with the same or corresponding reference numerals.
Im Gegensatz zu der ersten Ausführungsform, bei der die von einem Patienten ausgeübte Zugkraft Fz über einen Hebel auf einen Druckkraftsensor Dl geleitet wird, wird die Zugkraft Fz bei dieser zweiten Ausführungsform mittels eines Dehnungs- messstreifens oder eines bekannten DMS-Zugstabes D2 erfasst. In contrast to the first embodiment, in which the tensile force F z exerted by a patient is directed to a pressure force sensor D 1 via a lever, the tensile force F z in this second embodiment is detected by means of a strain gauge or a known strain gauge D 2.
Zu diesem Zweck weist das Trainingsgerät eine Welle W auf, die mit ihrem einen Ende an der ersten Befestigungseinrichtung 13 und mit ihrem anderen Ende an der zweiten Befestigungseinrichtung 14 angreift. Die Welle W ist vorzugsweise mittels eines ersten Lagers LI (insbesondere eines Gleitlagers) an der ersten Halteeinrich- tung 102 und/oder mittels eines zweiten Lagers L2 (insbesondere eines Gleitlagers) an der zweiten Halteeinrichtung 103 gelagert, so dass sich der in Figur 9(B) gezeigte Kraftverlauf ergibt. Dabei sind ein oder mehrere Dehnungsmessstreifen D2 (DMS) auf zumindest einen Abschnitt der Welle W aufgebracht, oder es ist zumindest ein Abschnitt der Welle in Form eines DMS-Zugstabes D2 ausgebildet. For this purpose, the training device has a shaft W, which acts with its one end on the first fastening device 13 and with its other end on the second fastening device 14. The shaft W is preferably connected to the first holding device by means of a first bearing LI (in particular a slide bearing). Device 102 and / or by means of a second bearing L2 (in particular a sliding bearing) mounted on the second holding device 103, so that the force curve shown in Figure 9 (B) results.
