Abstract

Into the loading path passing through the body and onto the ground, a load sensor is introduced. Should loading exceed and/or undershoot a threshold, a signal is generated. This is connected to an output unit which gives a warning stimulus to the individual.

Description

Die Erfindung betrifft eine Vorrichtung zur Signalisierung der Körperbelastung, vorzugsweise von Extremitäten, einer Person.The invention relates to a device for signaling body strain, preferably from extremities, a person.

Bei Beinbrüchen ist es in einigen Fällen wichtig, diese nach ihrer Behandlung nur teilweise zu belasten. Dabei ist es nötig, die Belastung beim Gehen auf die verletzte Stelle stufenweise - innerhalb von Tagen oder Wochen - zu erhöhen. Die Belastung erfolgt aber durch den Patienten rein subjektiv, da durch die auftretenden Schmerzen die Belastung höher bzw. niedriger empfunden wird.In the case of broken legs, it is important in some cases only after their treatment to partially burden. It is necessary to reduce the burden of walking on the injured Increase the position gradually - within days or weeks. The load is done subjectively by the patient, because of the pain the burden is felt higher or lower.

Es besteht somit das dringende Bedürfnis nach einer Vorrichtung, die dem Patienten bzw. dem Arzt eine wirksame und effektive Kontrolle über die Höhe der Belastung gibt.There is therefore an urgent need for a device that the patient or the doctor an effective and effective control over the amount of the load gives.

Diese Aufgabe wird dadurch gelöst, daß im Kraftfluß ein Belastungssensor angeordnet ist, der bei Über- und/oder Unterschreiten einer Belastungsgrenze ein Signal generiert, das mit einer Ausgabeeinheit verbunden ist, die einen wahrnehmbaren Reiz auf eine Person ausübt.This object is achieved in that a load sensor in the power flow is arranged, the one when exceeding and / or falling below a load limit Signal generated, which is connected to an output unit, the one perceivable stimulus on a person.

Weitere vorteilhafte Ausgestaltungen sind in den Ansprüchen 1 bis 7 beschrieben. Die Erfindung wird anhand eines Ausführungsbeispieles beschrieben, das in der einzigen Figur der beigefügten Zeichnung schematisch in einer bevorzugten Ausführungsform dargestellt ist.Further advantageous embodiments are described in claims 1 to 7. The invention is described using an exemplary embodiment, which in the single figure of the accompanying drawing schematically in a preferred Embodiment is shown.

Die Fig. 1 zeigt einen Vertikalschnitt durch einen Gipsverband mit darin angeordnetem Fuß. Fig. 1 shows a vertical section through a cast with disposed therein foot.

In Fig. 1 bezeichnet 1 den Fuß eines gebrochenen Beines. Fuß 1 ist in bekannter Weise von einem Gipsverband 2 umhüllt. Die durch das Eigengewicht der Person erzeugte Gewichtskraft wird über die zu heilende Extremität 1, den Sensor 3 in die Belastungsfläche 4, die beispielsweise der Fußboden ist, eingeleitet. Der Kraftfluß geht somit von Fuß 1 über Sensor 3 und Gipsverband 2 in die Bodenfläche 4. Im Kraftfluß zwischen Fuß 1 und Bodenfläche 4 ist der erfindungsgemäße Sensor 3 angeordnet. Der Kraftsensor 3 kann somit die erzeugte Kraft messen und über Signalleitung 5 an eine Auswerteeinheit 6 weitergeben, die das Kraftsignal mit einer über Einstelleinheit 7 voreingestellte Belastungsgrenze vergleicht. Wird diese Belastungsgrenze überschritten, so wird von der Auswerteeinheit 6 ein Ausgabesignal generiert, das über die Signalleitung 8 einer akustischen Ausgabeeinheit 9 weitergegeben wird. Der von der akustischen Ausgabeeinheit generierte akustische Reiz kann über die Ohren des Patienten wahrgenommen werden und dieser kann das Über- und/oder Unterschreiten der Belastungsgrenze erkennen und den Fuß entlasten.In Fig. 1, 1 designates the foot of a fractured bone. Foot 1 is encased in a plaster cast 2 in a known manner. The weight force generated by the person's own weight is introduced via the extremity 1 to be healed, the sensor 3, into the load area 4 , which is the floor, for example. The power flow thus goes from foot 1 via sensor 3 and plaster cast 2 into floor surface 4 . The sensor 3 according to the invention is arranged in the power flow between the foot 1 and the bottom surface 4 . The force sensor 3 can thus measure the force generated and pass it on via signal line 5 to an evaluation unit 6 which compares the force signal with a load limit preset via the setting unit 7 . If this load limit is exceeded, the evaluation unit 6 generates an output signal which is passed on to an acoustic output unit 9 via the signal line 8 . The acoustic stimulus generated by the acoustic output unit can be perceived via the patient's ears and the patient can recognize whether the load limit has been exceeded and / or fallen below and relieves the foot.

Mittels der Einstelleinheit kann die Belastungsgrenze während des Heilungsprozesses stufenweise, z. B. in Schritten von 50 Newton, erhöht werden.The load limit can be adjusted during the Healing process gradually, e.g. B. in steps of 50 Newtons.

In einer mechanischen alternativen Ausführungsform ist der Sensor 3 als Feder ausgebildet, die in Abhängigkeit von der auftretenden Belastung komprimiert wird. Eine damit verbundene Stützplatte 10 ist so durch geeignete Vorverformung ausgestaltet, daß sie bei Überschreiten einer bestimmten Verformung nach Art eines Knackfrosches in eine andere Form überspringt. Dieses Überspringen kann sowohl als akustischer Reiz wie auch als taktiler Reiz, der auf die untere Fußfläche wirkt, vom Patienten wahrgenommen werden.In a mechanical alternative embodiment, the sensor 3 is designed as a spring that is compressed depending on the load that occurs. An associated support plate 10 is designed by suitable pre-deformation so that it jumps into a different shape when a certain deformation is exceeded in the manner of a cracked frog. This skipping can be perceived by the patient both as an acoustic stimulus and as a tactile stimulus that acts on the lower foot surface.

Die Einstellung der Belastungsgrenze kann sowohl durch entsprechenden Austausch der Stützplatte 10 oder des Sensors 3, bzw. seiner Feder durch eine andere Feder mit anderer Federkennlinie bewerkstelligt werden.The setting of the load limit can be accomplished both by correspondingly replacing the support plate 10 or the sensor 3 , or its spring by another spring with a different spring characteristic.

Besonders vorteilhaft ist es, wenn die Vorrichtung wiederverwendbar ausgebildet ist, so dass nach Beendigung des Heilungsprozesses sie bei einem weiteren Patienten wieder zum Einsatz kommen kann. It is particularly advantageous if the device is designed to be reusable, so that after the healing process is over, they see another patient can be used again.  

Die Austauschbarkeit der Vorrichtung wird erleichtert, wenn sie im Kraftfluß außerhalb des Verbandes angeordnet ist, d. h., nicht zwischen Fuß und Verband, sondern aussen am Verband zwischen dem Verband und der Belastungsfläche 4.The interchangeability of the device is facilitated if it is arranged in the power flow outside the bandage, ie not between the foot and the bandage, but on the outside of the bandage between the bandage and the loading surface 4 .

Die Vorrichtung kann auch mit Vorteil beispielsweise im Schuh oder im Absatzes eines Schuhes angeordnet werden.The device can also be used, for example, in the shoe or in the heel a shoe can be arranged.

Besonders einfach ist der Austausch, wenn die Vorrichtung als Einlegesohle gestaltet ist.Replacement is particularly easy when the device is an insole is designed.

Es ist somit ein Hilfsmittel zur Verfügung gestellt, das an Bandagen, im Gips oder auch Schuhen befestigt werden kann und dem Patienten mitteilt - durch Geräusche und Vibration -, daß er seinen Fuß zu hoch belastet. It is therefore a tool that is available on bandages, in plaster or shoes can also be attached and informed to the patient - by noise and vibration - that he puts too much strain on his foot.
