Abstract

The device consists of a gradient sensor, fitted to an area of the body, which enables it to sense the gradient of the spine. Should the gradient become undesirable, i.e. capable of causing damage, the sensor emits an acoustic or optical alarm. The gradient sensor (1), comprises a glass or plastic tube containing a conductive ball (3), which begins to roll at a specific slope and thus makes contact between two electrodes (4, 5) at the end of the path. Two contacts (6, 6') serve as connections to an evaluation circuit, comprising a comparator, an oscillator, an amplifier and a speaker. When the gradient sensor shorts out the comparator input, the oscillator and amplifier are switched on to give an alarm. USE/ADVANTAGE - Aids in preventing posture and lifting errors leading to slipped discs.

Description

In der Krankenstatistik spielen Schäden an der Wirbel­ säule eine immer größere Rolle. Diese Schäden sind zum überwiegenden Teil auf eine Überlastung der Bandschei­ ben zurückzuführen. Die Überlastung der Bandscheiben ist durch Haltungsfehler bedingt, die bei der beruf­ lichen Tätigkeit, aber zum Teil auch bei Freizeitbe­ schäftigungen auftreten. Der durch Bandscheibenschäden verursachte volkswirtschaftliche Schaden geht in die Milliarden.Damage to the vertebrae plays a role in the medical statistics column is playing an increasingly important role. This damage is due to predominantly due to overloading of the bandschei ben attributed. Overloading the intervertebral discs is caused by mistakes in posture at work activity, but also in part for leisure activities occupations occur. The one due to spinal disc damage economic damage caused goes into the Billions.

Der Erfindung liegt die Aufgabe zugrunde, ein elektro­ nisches Kontrollgerät anzugeben, welches bei nicht mehr vertretbarer Neigung der Wirbelsäule anspricht und ein akustisches oder optisches Warnsignal auslöst. Außerdem soll das elektronische Kontrollgerät möglichst leicht und mikrominiaturisierbar sein, damit es am Körper einer Person mühelos getragen werden kann. Diese Auf­ gabe wird erfindungsgemäß durch ein elektronisches Kon­ trollgerät mit den Merkmalen des Anspruchs 1 gelöst.The invention has for its object an electro African control device to indicate which no longer acceptable inclination of the spine and responds triggers an acoustic or visual warning signal. Furthermore the electronic control device should be as light as possible and be microminiaturizable so it is on the body can be carried easily by a person. This on gift is according to the invention by an electronic con Trollgerät solved with the features of claim 1.

Die Erfindung wird im folgenden an einem Ausführungs­ beispiel erläutert.The invention is based on an embodiment example explained.

Die Fig. 1 zeigt eine Vorrichtung, die erfindgungsge­ mäß die Funktion eines Neigungssensors ausüben kann. Der Neigungssensor 1 der Fig. 1 besteht aus einem Glas- oder Kunststoffröhrchen 2 mit z. B. einer leit­ fähigen Kugel 3, die bei entsprechender Neigung des Neigungssensors 1 zu rollen beginnt und dabei Kontakt zwischen zwei den Rollweg begrenzenden leitfähigen Elektroden 4 und 5 herstellt. Am Neigungssensor 1 der Fig. 1 sind Kontakte 6 und 6′ angebracht, die mit den Elektroden 4 und 5 im Inneren des Gehäuses 2 in elektrisch leitender Verbindung stehen. Fig. 1 shows a device that can perform the function of an inclination sensor according to the invention. The inclination sensor 1 of FIG. 1 consists of a glass or plastic tube 2 with z. B. a conductive ball 3 , which begins to roll with a corresponding inclination of the inclination sensor 1 and thereby makes contact between two conductive electrodes 4 and 5 delimiting the taxiway. At the inclination sensor 1 of FIG. 1 are mounted 6 and 6 'contacts associated with the electrodes 4 and 5 in the interior of the housing 2 in electrically conductive connection.

Die Fig. 2 zeigt den Neigungssensor 1 zusammen mit einer Auswerteelektronik 7. Die Auswerteelektronik 7 weist einen Komparator 8, einen Oszillator 9 und einen Sound-Verstärker 10 auf. Zwischen den Punkten III und IV der Auswerteelektronik liegt die Betriebsspannung. Zwischen den Punkt III und Masse (IV) ist ein Span­ nungsteiler geschaltet, der aus den Widerständen 11 und 12 besteht. Der Punkt I der Auswerteelektronik ist mit dem Neigungssensor 1, mit dem einen Eingang des Komparators 8 und über einen Widerstand 13 mit dem Punkt III (Betriebsspannung) verbunden. Der andere Eingang des Komparators 8 ist mit dem Verbindungspunkt der Widerstände 11 und 12 des Spannungsteilers ver­ bunden. Wenn der Neigungssensor 1 anspricht, wird der Punkt I der Auswerteelektronik über den kurzgeschlos­ senen Neigungssensor 1 nach Masse (IV) gezogen. Dies erkennt der Komparator 8, da sein einer Eingang mit dem Punkt I verbunden ist. Wenn der Neigungssensor 1 anspricht, schaltet der Komparator 8 den Oszillator 9 und den nachgeschalteten Sound-Verstärker 10 ein. Der Sound-Verstärker 10 liefert über den Punkt II das er­ forderliche Signal an den Schall-Wandler 14. Fig. 2 shows the inclination sensor 1 together with evaluation. 7 The evaluation electronics 7 has a comparator 8 , an oscillator 9 and a sound amplifier 10 . The operating voltage lies between points III and IV of the evaluation electronics. Between the point III and ground (IV) a voltage divider is connected, which consists of the resistors 11 and 12 . The point I of the evaluation electronics is connected to the inclination sensor 1 , to the one input of the comparator 8 and to the point III (operating voltage) via a resistor 13 . The other input of the comparator 8 is connected to the connection point of the resistors 11 and 12 of the voltage divider. When the inclination sensor 1 responds, point I of the evaluation electronics is pulled to ground (IV) via the short-circuited inclination sensor 1 . The comparator 8 recognizes this since its one input is connected to the point I. When the inclination sensor 1 responds, the comparator 8 switches on the oscillator 9 and the downstream sound amplifier 10 . The sound amplifier 10 delivers the required signal to the sound converter 14 via point II.
