DESCRIPTIONDESCRIPTION
- La présente invention concerne les appareils de gymnastique ou de rééducation musculaire, dans lesquels l'effort antagoniste appliqué au patient The present invention relates to gymnastics or muscle reeducation apparatus, in which the antagonistic effort applied to the patient
s'exerce au moyen d'un fil souple relié au membre en exercice. is exercised by means of a flexible wire connected to the exercising member.
- La force est contrMée en intensité par la tension du fil et en direction par le choix judicieux du point par lequel sort le fil de l'appareil, point que nous conviendrons d'appeler "point d'application de la force". Ainsi la direction de la force est obtenue par la droite qui relie le - The force is controlled in intensity by the tension of the thread and in direction by the judicious choice of the point by which the wire of the apparatus leaves, point which we will agree to call "point of application of the force". So the direction of the force is obtained by the line that connects the
membre en exercice, au point d'application de la force. member in office, at the point of application of the force.
Les appareils connus de ce genre sont: - des "tenseurs" constitués par des élastiques ou des ressorts, utilisés en attachant l'une des extrémités à un point d'encrage qui constitue Known devices of this type are: - "tensors" constituted by elastics or springs, used by attaching one of the ends to an inking point which constitutes
le point d'application de la force.the point of application of the force.
- des systèmes à poids et à poulie, dans lesquels les poids contrôlent la tension du fil (donc le module de la force) et la poulie, par sa - weight and pulley systems, in which the weights control the tension of the yarn (thus the modulus of force) and the pulley, by its
propriété "de renvoi d'angle", le point d'application de la force. "Angle of Return" property, the point of application of the force.
Ces systèmes ont, entre autres inconvénients, celui de très mal contr8ler l'intensité de la force appliquée au muscle. Dans le premier cas, celleci est proportionnelle à l'élongation, c'est-à-dire au déplacement du membre, tandis que dans le second cas, elle reste constante. Ces deux cas sont aussi éloignés l'un que l'autre des conditions idéales qui nécessitent un contrôle très précis de la force afin de la moduler en fonction des problèmes de rééducation qui sont des cas d'espèce. Dans certains cas par exemple, on souhaite asservir la force de telle façon que le mouvement s'effectue à une These systems have, among other disadvantages, that of very poorly control the intensity of the force applied to the muscle. In the first case, it is proportional to the elongation, that is to the movement of the limb, while in the second case, it remains constant. These two cases are as far apart as ideal conditions which require a very precise control of the force in order to modulate it according to the rehabilitation problems which are specific cases. In some cases, for example, it is desired to control the force in such a way that the movement takes place at a
vitesse déterminée, etc...determined speed, etc ...
-2- Le dispositif suivant l'invention évite ces inconvénients grâce à un contrôle électronique de la tension du fil. Accessoirement, il simplifie le choix du point d'application de la force et évite l'emploi des systèmes The device according to the invention avoids these drawbacks by means of an electronic control of the tension of the thread. Incidentally, it simplifies the choice of the point of application of the force and avoids the use of the systems.
archaïques connus sous le nom de "cage à poulie". archaic known as the "pulley cage".
L'invention sera de toute façon mieux comprise à partir d'un mode préféré de réalisation, donné ici à titre indicatif et, bien entendu, The invention will in any case be better understood from a preferred embodiment, given here as an indication and, of course,
nullement limitatif.in no way limiting.
Comme on peut le voir sur la figure 1, le dispositif suivant l'invention consiste essentiellement en un rail ou guide 1 réalisé en profilé quelconque, par exemple un tube carré comportant une fente à l'avant. Sur ce rail coulisse un distributeur de fil 2 qui peut donc se déplacer sur toute la longueur de 1 et peut, par un dispositif de blocage convenable (une vis pression par exemple) être immobilisé pendant l'utilisation de l'appreil. On peut ainsi délivrer du fil permettant d'appliquer une force dont la direction est déterminée par la position relative de 2 par rapport à l'organe en As can be seen in Figure 1, the device according to the invention consists essentially of a rail or guide 1 made of any profile, for example a square tube having a slot at the front. On this rail slides a wire feeder 2 which can move over the entire length of 1 and can, by a suitable locking device (a screw pressure for example) be immobilized during use of the device. It is thus possible to deliver wire for applying a force whose direction is determined by the relative position of 2 relative to the body in
exercice.exercise.
Pour diminuer le frottement du fil sur le coulisseur 2, celui-ci To reduce the friction of the wire on the slide 2, this one
peut avantageusement comporter des roulettes comme schématisé sur la figure 2. can advantageously comprise rollers as shown schematically in Figure 2.
Le fil arrive dans l'axe de 1 et subit un renvoi d'angle par les roues à gorges 6 et 7 dont les axes sont perpendiculaires au rail 1. Le fil passe ensuite entre les rouleaux 8 et 9 dont l'axe est cette fois parallèle à 1, ce qui permet un nouveau renvoi d'angle dans un plan perpendiculaire au précecent. La combinaison de ces deux angles permet d'effectuer une traction du fil dans toutes les directions sans occasionner des frottements probihitifs. -3- En amont du distributeur 2, on exerce sur le fil une traction T dont la direction est parallèle au rail 1. A la sortie du distributeur, on utilise la force F dont la direction, on l'a vu, est quelconque. Avec des frottements faibles, on a la relation: The wire arrives in the axis of 1 and undergoes a bevel gear by the grooved wheels 6 and 7 whose axes are perpendicular to the rail 1. The wire then passes between the rollers 8 and 9 whose axis is this time parallel to 1, which allows a new return angle in a plane perpendicular to the prececent. The combination of these two angles makes it possible to pull the wire in all directions without causing probihitive friction. -3- Upstream of the distributor 2, is exerted on the wire a traction T whose direction is parallel to the rail 1. At the outlet of the distributor, the force F is used whose direction, as we have seen, is any. With weak friction, we have the relation:
/ F = F /T7= T/ F = F / T7 = T
Ce qui signifie que l'intensité de la force F est égale à la Which means that the intensity of the force F is equal to the
traction du fil.pulling the thread.
Examinons maintenant le moyen de réaliser cette traction en se reportant à la figure 3. Le fil s'enroule sur un treuil 3 de rayon R. Pour assurer la traction T, il faut appliquer au treuil un couple C égal à: Let us now examine the means of carrying out this traction by referring to FIG. 3. The wire is wound on a winch 3 of radius R. To ensure the traction T, it is necessary to apply to the winch a pair C equal to:
C = T.RC = T.R
Ceci est réalisé au moyen du moteur électrique 5 qui peut dans This is achieved by means of the electric motor 5 which can in
certains cas être suivi d'un réducteur 4 afin d'augmenter le couple. some cases be followed by a reducer 4 to increase the torque.
Il est avantageux d'utiliser un moteur électrique à courant continu It is advantageous to use a DC electric motor
dans lequel on a généralement un couple proportionnel au courant d'alimen- in which one generally has a proportional torque to the current of
tation dudit moteur. Dans ces conditions, le contrôle du couple et par suite de la force F s'effectue par une régulation du courant d'alimentation du moteur. Dans ces conditions, le contrôle du courant peut suivre une loi aussi complexe que souhaité. La figure 4 donne un exemple de régulation au moyen d'un transistor de puissance 10 qui est attaqué par l'amplificateur opérationnel 11 dont l'entrée positive reçoit une tension de consigne V(t) qui est proportionnelle au courant I traversant le moteur. La contre réaction s'effectue par la tension R I aux bornes d'une résistance R parcourue par le courant I. Elle est appliquée à l'entrée négative de l'amplificateur différentiel 11, de sorte que l'on a: said engine. Under these conditions, the control of the torque and as a result of the force F is effected by a regulation of the motor supply current. Under these conditions, the current control can follow a law as complex as desired. FIG. 4 gives an example of regulation by means of a power transistor 10 which is driven by the operational amplifier 11 whose positive input receives a setpoint voltage V (t) which is proportional to the current I flowing through the motor. The counter-reaction is effected by the voltage R I across a resistor R traversed by the current I. It is applied to the negative input of the differential amplifier 11, so that:
V(t) = R I(t).V (t) = R I (t).
-4- Cette possibilité de contrôle de force peut être utilisée diversement: - On peut appliquer une tension constante ( V(t) = cte) dans ce cas, la force de traction reste constante quel que soit le déplacement. On peut également asservir la force au résultat d'une mesure d'élongation telle qu'elle peut être effectuée au moyen d'un codeur angulaire 12 calé sur l'axe du treuil 3, convenablement traitée pour obtenir les résultats suivants: a) asservissement de la force de façon à ce que la vitesse de déplacement du membre soit constante, ce qui permet par exemple de compenser la fatigue du patient. Dans d'autres cas, on pourra moduler la force afin d'obtenir une vitesse variable en fonction de la position du membre ou en fonction de paramètres extérieurs (variation temporelle de l'effort, pouls, etc...). b) asservissement de la force à une loi quelconque liée à la position du membre qui est reliée elle-même à la mesure d'élongation, -4- This possibility of force control can be used variously: - One can apply a constant tension (V (t) = cte) in this case, the traction force remains constant whatever the displacement. The force can also be enslaved to the result of an elongation measurement such that it can be carried out by means of an angular encoder 12 wedged on the axis of the winch 3, suitably treated to obtain the following results: a) servo-control of the force so that the speed of movement of the limb is constant, which allows for example to compensate for patient fatigue. In other cases, it will be possible to modulate the force in order to obtain a variable speed according to the position of the limb or according to external parameters (temporal variation of the effort, pulse, etc ...). b) enslavement of the force to any law related to the position of the member which is itself connected to the elongation measure,
repérée lors du premier mouvement et mise en mémoire. spotted during the first movement and stored.
c) asservissement de la force à des paramètres extérieurs tels: loi temporelle des montées en puissance de l'effort, vitesse du pouls, c) enslavement of the force to external parameters such as: temporal law of the increases in power of the effort, velocity of the pulse,
pression artérielle, etc...blood pressure, etc.
La mesure de l'élongation est par ailleurs utilisable pour calculer The measurement of elongation can also be used to calculate
le travail effectué ou la puissance développée instantanément. work done or power developed instantly.
Le dispositif suivant l'invention peut être utilisé dans les hôpitaux ou cliniques, chez les kynésithérapeutes, dans les salles de The device according to the invention can be used in hospitals or clinics, at physiotherapists, in theaters
gymnastique ou chez les particuliers. gymnastics or at home.
