Description

Die Erfindung befaßt sich mit dem Schalten von Bewegungsfunktionen an Einrichtungen zur Lagerung von Patienten.The invention is concerned with the switching of movement functions in devices for patient positioning.

Bei Patientenlagerungseinrichtungen sind motorisch verstellbare Bewegungsfunktionen zur Lageänderung von Patienten häufig durch doppelt vorhandene, voneinander unabhängige elektrische Schaltkreise zu schalten. Tritt in einem der elektrischen Schaltkreise ein Fehler auf, so wird die Bewegung der Lagerungseinrichtung sofort unterbrochen oder nicht ausgelöst. Der Grund hierfür liegt darin, daß jede Gefährdung eines Patienten durch eine fehlerhafte Bewegungsfunktion der Lagerungseinrichtung ausgeschlossen werden muß.In patient positioning devices, motor-adjustable movement functions for changing the position of patients are often to be switched by double, independent electrical circuits. If a fault occurs in one of the electrical circuits, the movement of the storage device is immediately interrupted or not triggered. The reason for this is that any risk to a patient due to an incorrect movement function of the positioning device must be excluded.

Es ist bereits bekannt, an einer Schalt- oder Bedienungseinheit für eine Patientenlagerungseinrichtung zur Betätigung der getrennten Schaltkreise zwei Schalter vorzusehen, wobei die gewünschte Bewegungsfunktion der Pateintenlagerungseinrichtung nur dann ausgelöst wird, wenn beide Schalter betätigt werden, d.h. die beiden Schalter eine UND-Funktion bilden, wie sie für sich z.B. in dem Buch von Tietze, Schenk "Halbleiterschaltungstechnik", fünfte Auflage 1980, S. 140, 141 und in "Instruments & Control Systems", Vol. 34, S. 864 beschrieben ist. Damit ist insbesondere eine Sicherheit gegeben, daß eine Bewegung der Lagerungseinrichtung in jedem Falle unterbrochen werden kann, auch wenn an einem Schalter einmal die Kontaktelemente aneinander hängen bleiben oder dergleichen.It is already known to provide two switches on a switching or operating unit for a patient positioning device for actuating the separate circuits, the desired movement function of the patient positioning device being triggered only when both switches are actuated, i.e. the two switches form an AND function, as they are e.g. in the book by Tietze, Schenk "Semiconductor circuit technology", fifth edition 1980, pp. 140, 141 and in "Instruments & Control Systems", vol. 34, p. 864. This ensures in particular that a movement of the bearing device can be interrupted in any case, even if the contact elements stick to one another or the like on a switch.

Diese Lösung erfordert jedoch einen erhöhten Flächenbedarf an der Schalteinheit und damit eine entsprechende bauliche Größe, da diese Schalteinheit für die Vielzahl von Bewegungsabläufen der Lagerungseinrichtung auch eine Vielzahl von Schaltern aufweist, deren Betätigungselemente nicht beliebig verkleinert werden können. Zudem ist die jeweilige Bedienung zweier Schalter umständlich.However, this solution requires an increased space requirement on the switching unit and thus a corresponding structural Size, since this switching unit for the multitude of movement sequences of the storage device also has a large number of switches, the actuating elements of which cannot be reduced arbitrarily. In addition, the operation of two switches is cumbersome.

Ferner sind zur mindestens annähernd gleichzeitigen Schaltung verschiedener Funktionen aus der US-A-3 917 917 und der FR-A-1 316 747 Schalteranordnungen bekannt, umfassend zwei elektrische Kontaktelemente aufweisende Schalter, von denen mindestens ein Schalter als Folientaster ausgebildet ist, der eine Kontaktelemente tragende flexible Basisfolie und eine in Richtung auf diese elastisch auslenkbare, die Gegenkontaktelemente tragende Schaltfolie aufweist, wobei der andere Schalter in Tastrichtung hinter dem Folientaster derart angeordnet ist, daß er durch einen in Tastrichtung auf den Folientaster ausgeübten und den Betätigungsdruck des Folientasters überschreitenden Druck auf den Folientaster betätigt wird.Furthermore, for the at least approximately simultaneous switching of different functions from US-A-3 917 917 and FR-A-1 316 747 switch arrangements are known, comprising two switches having electrical contact elements, of which at least one switch is designed as a membrane switch, which is a contact element load-bearing flexible base film and a switching film which is elastically deflectable in the direction of this and carries the counter-contact elements, the other switch being arranged behind the film button in the sense of the button in such a way that it is exerted by a pressure exerted on the button in the direction of the button and which exceeds the actuating pressure of the button Membrane button is pressed.

Der Erfindung liegt die Aufgabe zugrunde, das Schalten von Bewegungsfunktionen an Patientenlagerungseinrichtungen mit einer Schalteranordnung zu ermöglichen, die einen geringen Platzbedarf hat und eine bequeme Bedienung ermöglicht.The invention has for its object to enable the switching of movement functions on patient positioning devices with a switch arrangement that takes up little space and enables convenient operation.

Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch angegebenen Merkmale gelöst.This object is achieved according to the invention by the features specified in the patent claim.

Bei der erfindungsgemäßen Lösung wird also beispielsweise an einem Schaltgerät nur der der Tastfläche des Folientasters entsprechende Platz benötigt. Auch in Tastrichtung ist die Bauhöhe der Schalteranordnung sehr gering, da der Folientaster selbst nur wenig Platz beansprucht. Durch Druck auf den Folientaster wird zunächst dieser betätigt. Durch weiteres Eindrücken des flexiblen Folientasters kann dann der darunter bzw. dahinter angeordnete elektrische Schalter betätigt werden. Dabei kann dieser dahinterliegende Schalter ebenfalls wieder als Folientaster oder auch als mechanischer Druckschalter ausgebildet sein. Im Falle von mehreren hintereinander angeordneten Folientastern ist es hinsichtlich der Bauhöhe der gesamten Schalteranorndung vorteilhaft, wenn die Basisfolie des in Tastrichtung vorne liegenden Folientasters jeweils die Schaltfolie des in Tastrichtung folgenden Folientasters bildet.In the solution according to the invention, for example, only the space corresponding to the touch surface of the membrane push button is required on a switching device. The overall height of the switch arrangement is also very low in the pushbutton direction, since the membrane switch itself takes up little space. By pressing the membrane button, this is first actuated. By pushing the flexible membrane button in further, the electrical switches arranged below or behind them are actuated. This switch located behind it can also be designed as a membrane switch or as a mechanical pressure switch. In the case of a plurality of membrane switches arranged one behind the other, it is advantageous with regard to the overall height of the entire switch arrangement if the base film of the membrane switch located at the front in the scanning direction forms the switching membrane of the membrane switch following in the scanning direction.

Solange bei der erfindungsgemäßen Lösung nicht sämtliche Schalter gleichzeitig versagen, kann die Bewegungsfunktion der Lagerungseinrichtung in jedem Falle unterbrochen werden, selbst wenn an einem der Schalter die Kontaktelemente ungewollt geschlossen bleiben, beispielsweise aneinander kleben.As long as not all switches fail at the same time in the solution according to the invention, the movement function of the bearing device can be interrupted in any case, even if the contact elements on one of the switches remain closed unintentionally, for example stick to one another.

Die Erfindung wird in der folgenden Beschreibung in Verbindung mit den beigefügten Figuren anhand von Ausführungsbeispielen näher erläutert. Es zeigen:

  • Fig. 1 ein Beispiel zweier übereinander angeordneter Folientaster,
  • Fig. 2 eine abgewandelte Ausführungsform zweier übereinander angeordneter Folientaster,
  • Fig. 3 eine Schalteranordnung mit einem Folientaster und einem darunter angeordneten mechanischen Druckschalter,
  • Fig. 4 ein Schaltungsbeispiel für die erfindungsgemäße Schalteranordnung und
  • Fig. 5 eine schematische Darstellung eines Bedienungsgerätes unter Verwendung der erfindungsgemäßen Schalteranordnungen.
The invention is explained in more detail in the following description in conjunction with the accompanying figures using exemplary embodiments. Show it:
  • 1 shows an example of two membrane switches arranged one above the other,
  • 2 shows a modified embodiment of two membrane keys arranged one above the other,
  • 3 shows a switch arrangement with a membrane switch and a mechanical pressure switch arranged underneath,
  • Fig. 4 shows a circuit example for the switch arrangement according to the invention and
  • Fig. 5 is a schematic representation of an operating device using the switch arrangements according to the invention.

In den Figuren 1 bis 5 sind gleiche Teile jeweils mit gleichen Bezugsziffern versehen.In Figures 1 to 5, the same parts are provided with the same reference numerals.

In Fig 1 sind zwei übereinander angeordnete Folientaster A und B dargestellt, wobei der zuerst betätigte Folientaster A aus einer flexiblen Frontfolie 1, einer flexiblen Schaltfolie 2, einer Distanzfolie 3 und einer flexiblen Basisfolie 4 besteht, und an der Schaltfolie 2 Leitkontakte 8 und an der Basisfolie 4 Leitkontakte 9 angeordnet sind. Die Leitkontakte 8 und 9 haben im Ruhestand eine Distanz x voneinander. Der hinter dem Folientaster A angeordnete Folientaster B besteht aus einer flexiblen Schaltfolie 5 mit Leitkontakten 10, einer Distanzfolie 6 und einer Basisfolie 7 mit Leitkontakten 11. Die Leitkontakte 10 und 11 haben im Ruhestand eine Distanz y voneinander.In Fig. 1 two superimposed membrane buttons A and B are shown, the first actuated membrane button A consists of a flexible front film 1, a flexible switching film 2, a spacer film 3 and a flexible base film 4, and 2 switching contacts 8 and on the switching film Base film 4 guide contacts 9 are arranged. The lead contacts 8 and 9 have a distance x from one another in the retired state. The membrane button B arranged behind the membrane button A consists of a flexible switching film 5 with guide contacts 10, a spacer film 6 and a base film 7 with guide contacts 11. The guide contacts 10 and 11 are at a distance y from one another in the idle state.

In Fig. 2 sind zwei übereinander angeordnete Folientaster A und B dargestellt, wobei hier die flexible Basisfolie 4 des Folientasters A und die flexible Schaltfolie des Folientasters B durch eine flexible Kombifolie 12 ersetzt sind. Auf der einen Seite der Kombifolie sind Leitkontakte 9 des Folientasters A, und auf der anderen Seite der Kombifolie 12 sind Leitkontakte 10 des Folientasters B angeordnet. Die Leitkontakte 9 und 10 sind in diesem Falle aber auch voneinander elektrisch nicht leitend getrennt.In Fig. 2 two superimposed membrane buttons A and B are shown, here the flexible base film 4 of the membrane button A and the flexible switching film of the membrane button B are replaced by a flexible combination film 12. Guide contacts 9 of the membrane switch A are arranged on one side of the combination film, and guide contacts 10 of the membrane switch B are arranged on the other side of the combination film 12. In this case, however, the guide contacts 9 and 10 are also electrically non-conductively separated from one another.

In Fig. 3 sind ein Folientaster A und ein darunter angeordneter sonstiger elektrischer Taster B dargestellt. Der Folientaster 1 besteht aus einer flexiblen Frontfolie 1, einer flexiblen Schaltfolie 2 mit Leitkontakten 8, einer Distanzfolie 3 und einer flexiblen Basisfolie 4 mit Leitkontakten 9. Der darunter angeordnete sonstige elektrische Schalter oder Taster B kann aus einem Gehäuse 13 bestehen und z.B. durcheinen Stift 14 geschaltet werden.In Fig. 3, a membrane switch A and another electrical button B arranged below it are shown. The membrane switch 1 consists of a flexible front film 1, a flexible switching film 2 with guide contacts 8, a spacer film 3 and a flexible base film 4 with guide contacts 9. The other electrical switch or button B arranged underneath can consist of a housing 13 and e.g. can be switched by a pin 14.

Fig. 4 zeigt wiederum eine Schalteranordnung gemäß Fig. 2 mit zwei hintereinander angeordneten Folientastern A und B. Die Kontaktelemente 8 und 9 des Folientasters A sind in eine Leitung 15 geschaltet. Die Kontaktelemente 10 und 11 des Folientasters B sind in eine Leitung 16 geschaltet. Die Leitungen 15 und 16 sind mit den Eingängen eines UND-Gliedes 17 verbunden. Man erkennt, daß das UND-Glied 17 nur dann ein Ausgangssignal liefern kann, wenn beide Folientaster A und B geschlossen sind. Im Hinblick auf Sicherheitserfordernisse wird die Schaltfunktion der in Fig. 4 dargestellten Schalteranordnung auch dann aufgehoben, wenn nur einer der Folientaster A und B öffnet.FIG. 4 again shows a switch arrangement according to FIG. 2 with two membrane buttons A and B arranged one behind the other. The contact elements 8 and 9 of the membrane button A are connected in a line 15. The contact elements 10 and 11 of the membrane switch B are connected in a line 16. The lines 15 and 16 are connected to the inputs of an AND gate 17. It can be seen that the AND gate 17 can only deliver an output signal if both membrane switches A and B are closed. With regard to safety requirements, the switching function of the switch arrangement shown in FIG. 4 is also canceled when only one of the membrane buttons A and B opens.

Fig. 5 zeigt ein Bedienungsgerät für eine Patientenlagerungseinheit mit einem Gehäuse 18 in dessen Oberfläche 19 eine Vielzahl von Schalteranordnungen 20 eingelassen sind. Jedes Paar von nebeneinander angeordneten Schalteranordnungen 20 dient zur Steuerung einer Bewegungsfunktion der Patientenlagerungseinrichtung in ihren beiden Richtungen. Jede der Schalteranordnungen 20 kann dabei nach einem der Ausführungsbeispiele entsprechend den Figuren 1 bis 3 ausgebildet sein. Man erkennt, daß die Oberfläche des Bedienungsgerätes praktisch verdoppelt werden müßte und die Bedienung sehr viel unübersichtlicher und umständlicher würde, wenn man nun in der herkömmlichen Weise jeweils zwei getrennte Schalter anstelle einer Schalteranordnung 20 vorsehen müßte.5 shows an operating device for a patient support unit with a housing 18 in the surface 19 of which a large number of switch arrangements 20 are embedded. Each pair of switch arrangements 20 arranged next to one another serves to control a movement function of the patient positioning device in both directions. Each of the switch arrangements 20 can be designed according to one of the exemplary embodiments corresponding to FIGS. 1 to 3. It can be seen that the surface of the operating device would have to be practically doubled and the operation would be much more confusing and cumbersome if one now had to provide two separate switches instead of one switch arrangement 20 in the conventional manner.
