When an edge of the mattress is loaded, a signal is generated that activates the alarm device.

Description

Überwachungseinrichtung  monitoring device
Die Erfindung betrifft Einrichtung zur Überwachung von Patientenbetten zwecks Erfassung des Aussteigens des Patienten aus dem Bett oder des Einsteigens desselben in das Bett, wobei das Bett mit einer Matratze und einer Alarmein- richtung zur Alarmierung des Pflegepersonals ausgestattet ist . The invention relates to a device for monitoring patient beds for the purpose of detecting the patient getting out of the bed or getting into the bed thereof, wherein the bed is provided with a mattress and an alarm device for alerting the nursing staff.
Üblicherweise sind die Patientenbetten mit einer zur Erzeu¬ gung eines Signals dienenden elektrischen Schaltvorrich- tung ausgerüstet. Bei diesen Vorrichtungen handelt es sich in der Regel um einen durch die im Bett liegende Person leicht erreichbaren und zu betätigenden Drucktastenschal¬ ter, der entweder oberhalb des Bettes aufgehängt sein oder auf dem Nachttisch liegen kann, oder um zwei derartige Schalter, von denen je einer so an einer Seite des Bettes angebracht ist, dass eine im Bett liegende Person bei Be¬ darf mit einer Hand einen der Schalter betätigen kann. Solche Schalter dienen dann zum Einschalten einer Signal- oder Alarmanlage, die sich nicht im gleichen Zimmer wie das Bett befindet, damit die im Bett liegende Person bei jedem Bedürfnis Hilfe herbeirufen kann, sei es beispielsweise um mehr oder weniger zugedeckt zu werden oder um eine Speise oder ein Getränk oder die Hilfe zum Verlassen des Bettes oder irgend etwas anderes zu erhalten. Anders verhält es sich bei Patienten, die nicht in der Lage oder nicht willens ist, einen Schalter zu betätigen, obwohl die Notwendigkeit dafür vorhanden wäre. Dies ist beispiels¬ weise bei Personen der Fall, die eine Veranlagung zum Usually, the patient beds with a serving for the generation of a signal electric supply ¬ Schaltvorrich- processing are fitted. In these devices, it is usually at an easily accessible by lying in bed person and operable pushbuttons scarf ¬ ter, the be suspended either from above the bed or may be at the bedside table, or two such switches, one each so attached to one side of the bed is that a person lying in bed at Be ¬ may operate one of the switches with one hand. Such switches are then used to switch on a signaling or alarm system that is not in the same room as the bed, so that the person lying in bed can summon help for every need, be it, for example, to be more or less covered or food or to get a drink or the help to get out of bed or anything else. The situation is different for patients who are unable or unwilling to operate a switch, although the need for it would be there. This is the example ¬ as in people the case that a predisposition to
Schlafwandeln aufweisen oder die beim Erwachen oder im all- gemeinen bei Dunkelheit Mühe haben, sich zurecht zu finden, sondern insbesondere bei all den Personen, die nicht daran denken können, dass sie sich melden sollten, wenn sie aus irgend einem Grund oder auch grundlos das Bett verlassen wollen. Zu diesen Personen gehören unter anderem auch sol- che, die an Demenz, insbesondere an Altersdemenz leiden.Sleepwalking, or who find it hard to get along on awakening, or generally in the dark, but especially of all the people who can not think that they should report if, for some reason or reason, they do Want to leave bed. These persons include, among others, those who suffer from dementia, especially senile dementia.
All diese Personen benötigen eine zur Erzeugung eines Signals bestimmte Schaltvorrichtung, die bereits dadurch akti¬ viert wird, dass die im Bett befindliche Person das Bett verlässt, also ohne dass sie die Schaltvorrichtung vorsätz- lieh betätigt. Selbstverständlich kann eine solche Schalt¬ vorrichtung mit einer der vorgenannten vorsätzlich zu betätigenden Schaltvorrichtungen parallel geschaltet sein. All these people need a certain to generate a signal switching device that is already characterized fourth acti ¬ that the person in the bed leaves the bed, so without them intentional the switching device borrowed operated. Of course, such a switching device ¬ be connected in parallel with one of the aforementioned deliberately actuated switching devices.
Zum vorgenannten Zweck sind beispielsweise aus der EP-A-1 961 406 oder der EP-A-2 368 535 Einrichtungen bekannt, bei denen entlang einer Längsseite der Matratze angeordnete Elemente mit Sensoren in Verbindung sind derart, dass durch die Belastung der Bettkante beim Versuch aufzustehen ein Signal ausgelöst wird, welches das Pflegepersonal alar- miert. Nachteilig ist bei diesen bekannten Einrichtungen, dass sie mechanisch relativ kompliziert sind und z.T. Modi¬ fikationen am Bett erfordern. For the above purpose, for example, from EP-A-1 961 406 or EP-A-2 368 535 devices are known in which arranged along a longitudinal side of the mattress elements with sensors in connection are such that by the loading of the edge of the bed when trying To get up a signal is triggered, which alerts the nursing staff. A disadvantage of these known devices that they are mechanically relatively complicated and sometimes require modi ¬ fications bed.
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung dieser Art zu schaffen, die einfacher aufgebaut ist und sich für jede Art von Bett einsetzen lässt. Erfindungsgemäss wird dies gelöst durch eine Überwachungs¬ einrichtung mit den kennzeichnenden Merkmalen des Patentanspruchs 1. The invention has for its object to provide a device of this kind, which is simpler in design and can be used for any type of bed. This is achieved according to the invention by a monitoring device having the characterizing features of patent claim 1.

Beim nachfolgend beschriebenen Ausführungsbeispiel ist die erfindungsgemässe Überwachungseinrichtung in eine Federkernmatratze integriert, weil sich solche Matratzen bevor¬ zugt für den angestrebten Zweck eignen. Selbstverständlich ist die Erfindung aber nicht auf Federkernmatratzen beschränkt, sondern kann auch mit Matratzenarten zur Anwendung kommen, die einen anderen Matratzenkern besitzen. When embodiment described below, the inventive monitoring device is integrated into an innerspring mattress, because such a mattress before ¬ Trains t suitable for the intended purpose. Of course, the invention is not limited to spring mattresses, but can also be used with mattress types that have a different mattress core.
Federkernmatratzen bestehen bekanntlich aus einem Kern mit einer Vielzahl von rasterförmig angeordneten Federelementen, auf beiden Seiten des Kerns angeordneten Polsterschichten und einem Bezug. Während bisher die Federelemente meist aus Stahlfedern bestehen, sind neuerdings auch Fe¬ derelemente aus Kunststoffen bekannt. Spring mattresses are known to consist of a core with a plurality of grid-shaped spring elements arranged on both sides of the core cushion layers and a cover. While so far the spring elements usually consist of steel springs, are now also Fe ¬ derelemente made of plastics known.
Der in Fig. 1 gezeigte Teil einer Federkernmatratze besitzt einen Kern 1, der seinerseits aus zwei Schichten 2, 3 und in diese Schichten eingebettete Federelemente 4 besteht.The part of a spring mattress shown in FIG. 1 has a core 1, which in turn consists of two layers 2, 3 and spring elements 4 embedded in these layers.
Dieser Kern ist beidseitig mit Polsterschichten 5, 6 versehen. Ein die gesamte Schichtanordnung umgebender Matratzenbezug ist in der vorliegenden Darstellung weggelassen. Die Federelemente 4 sind gleichmässig und rasterförmig über die Matratzenfläche verteilt. Dabei liegt je eine Reihe von Federelementen entlang den beiden Längskanten der Matratze. Die in diesen beiden Längsreihen angeordneten Federelemente kommen vorzugsweise für die beabsichtigte Überwachung zum Einsatz. This core is provided on both sides with cushioning layers 5, 6. A mattress cover surrounding the entire layer arrangement is omitted in the present illustration. The spring elements 4 are uniform and grid-shaped distributed over the mattress surface. In each case a row of spring elements lies along the two longitudinal edges of the mattress. The arranged in these two longitudinal rows spring elements are preferably used for the intended monitoring.
Ein in Fig. 2 und im Schnitt in Fig. 3 gezeigtes Federele¬ ment besteht aus einer flachen oberen Platte 7 und einer flachen unteren Platte 8. Zwischen den beiden Platten und einstückig mit ihnen verbunden erstrecken sich bogenförmige, nach aussen gewölbte Federbänder 9. Das Federelement besteht aus ermüdungsfreiem Kunststoff. Bei Belastung werden die beiden Platten entgegen der Rückstellkraft der Federbänder einander angenähert. A Federele ¬ ment shown in Fig. 2 and in section in Fig. 3 consists of a flat upper plate 7 and a flat lower plate 8. Between the two plates and integrally connected to them extend arcuate, outwardly curved spring bands 9. Das Spring element consists of fatigue-free plastic. When loaded, the two plates are approached against the restoring force of the spring bands.
An den Innenseiten der beiden Platten sind Sockel angeformt und zwar an der oberen Platte ein Sockel 10 und an der Innenseite der unteren Platten ein Sockel 11. Diese Sockel dienen der Aufnahme zweier zusammenwirkender Elemente eines Näherungsschalters 12. Zu diesem Zweck sind in bekannter Weise die Schalterteile mit Ausnehmungen und die Sockel mit federnd in die Ausnehmungen eingreifenden Nocken versehen. On the insides of the two plates base are formed on the upper plate and a base 10 on the inside of the lower plates, a base 11. These pedestals serve to receive two cooperating elements of a proximity switch 12. For this purpose, are known in the art Make the switch parts with recesses and the base with resiliently engaging in the recesses cam.
Unter Näherungsschaltern werden üblicherweise Schaltvorrichtungen verstanden, die auf Annäherung, d. h. ohne di- rekten Kontakt berührungsfrei reagieren. Für den Zweck die¬ ser Beschreibung soll der Begriff aber in einer erweiterten Bedeutung verwendet werden und auch Schalter umfassen, in denen in irgendeiner Weise ein Kontakt hergestellt wird, also auch solche, bei denen die Schaltfunktion pneumatisch oder hydraulisch ausgelöst wird. Under proximity switches are usually understood switching devices that react to approach, ie without direct contact without contact. For the purpose of the description ¬ ser but the term is intended to be used in a wider sense and also comprise switch in which a contact is made in any manner, including those in which the switching function is triggered pneumatically or hydraulically.
Der im vorliegenden Ausführungsbeispiel verwendete Nähe¬ rungsschalter besitzt in bekannter Weise ein Sensorelement 13 und ein passives Element 14, welches im Sensorelement durch Annäherung ein Signal erzeugt. Das Sensorelement ist mit Ausgangsleitungen 15 versehen, über welche das erzeugte Signal zu einem Alarmgeber oder dergl . geleitet wird. Die Näherungsschalter in allen Federelementen einer Reihe sind zusammengeschaltet, so dass an jeder Stelle der Längskante der Matratze ein Signal ausgelöst werden kann. In a known manner near ¬ proximity switch used in the present embodiment has a sensor element 13 and a passive element 14, which generates in the sensor element by approaching a signal. The sensor element is provided with output lines 15, via which the signal generated to an alarm or the like. is directed. The proximity switches in all spring elements of a row are connected together, so that at each point of the longitudinal edge of the mattress, a signal can be triggered.
Als Näherungsschalter kommen vorzugsweise solche Formen in Betracht, die ohne Berührung ein Signal abgeben, d.h. also magnetische, kapazitive, induktive und dergl., aber auch mechanische oder solche, deren Sensor eine angelegte Span¬ nung benötigt. As proximity switches are preferably those forms into consideration, which emit a signal without touching, ie, magnetic or capacitive, inductive and the like., But also mechanical or those whose sensor requires an applied clamping ¬ tion.
Wenn auf einer solchermassen ausgestatteten Matratze der Patient beim Aufstehen oder Abliegen sein Gewicht auf die Kante verlegt, wird mindestens ein oder aber mehrere Nähe- rungsschalter ansprechen und beispielsweise im Aufenthalts¬ raum des Pflegepersonals einen Alarm auslösen. When the patient places his weight on the edge when standing or lying down on such a fitted mattress, at least one or more Addressing switch and trigger an alarm, for example, in the stay ¬ room of the nursing staff.
Während für die vorstehend beschriebene Ausführungsform der Erfindung neuartige Federelemente aus Kunststoff verwendet werden, die sich wegen ihrer Form besonders gut für die Anbringung der Näherungsschalter in ihrem Inneren eignen, ist es für den Fachmann ohne weiteres möglich, bei herkömmlichen Federkernmatratzen die Federelemente der äusseren Reihen entlang der Matratzenkante in entsprechender Weise mit Näherungsschaltern zu versehen. While novel spring elements made of plastic are used for the embodiment of the invention described above, which are particularly well suited for the attachment of the proximity switch in its interior because of their shape, it is readily possible for the skilled person, in conventional spring mattresses along the spring elements of the outer rows to provide the mattress edge in a corresponding manner with proximity switches.
Federkernmatratzen eignen sich besonders gut für die Anbringung der Näherungssensoren in den Federelementen. Die Erfindung ist aber nicht auf Federkernmatratzen beschränkt, sondern ist auch mit anderen Formen von Matratzen zu verwirklichen, bei denen entlang ihrer Kanten Reihen von Näherungsschaltern angebracht werden können. Spring mattresses are particularly suitable for attaching the proximity sensors in the spring elements. The invention is not limited to innerspring mattresses, but is also to be realized with other forms of mattresses in which rows of proximity switches can be mounted along their edges.
