Definitions

  • the invention relates to a patient table with a table frame on which a patient table is vertically adjustable, which is attached to a lifting body which is connected to a base via a pair of scissors.
  • Patient positioning tables of this type are e.g. used in angiography to visualize blood vessels. It is desired that the patient is easily accessible to the doctor from all sides. Furthermore, the patient support plate should be able to be lowered far in the case of small dimensions of the table frame, so that the patient can easily be transferred from a bed to the patient support table. Finally, the lifting height should be so large that an optimal working height can be set for the doctor.
  • a patient table of the Arat mentioned is described in DE-AS 15 66 654.
  • the length and width of the table frame are relatively small; because of the articulation of the scissors linkage on the base of the base of the patient table, however, only a relatively small stroke is possible.
  • the invention has for its object to design a patient table of the type mentioned so that with simple construction elements, a small footprint of the table frame, a low minimum table height and an optimal working height can be achieved.
  • the lifting body and base consist of nestable box-shaped parts, and that the scissor linkage is articulated at the mutually facing ends of the lifting body and the base and is designed such that its arms can be deflected from the closed stretched position on both sides.
  • the scissor linkage is approximately horizontal when the upper end of the base and the lower end of the lifting body are approximately at the same level. From this position, the scissor linkage can be pivoted in both directions, so that on the one hand a pushing together of the lifting body and base and on the other hand a removal of the lifting body from the base is possible, which is determined by the dimensions of the scissor linkage.
  • the total lifting height is accordingly the result of the stroke of the scissor linkage, which is possible on both sides from the extended position.

Lifting body (7) and pedestal (1) consist of box-shaped parts that can be pushed into one another. The scissors linkage (3, 4a, 4b) is articulated on the mutually facing ends of the lifting body (7) and the base (1) and is designed in such a way that its arms (3, 4a, 4b) can be deflected to both sides from the closed stretched position .

Description

Die Erfindung betrifft einen Patientenlagerungstisch mit einem Tischgestell, an dem eine Patientenlagerungsplatte höhenverstellbar gelagert ist, die an einem Hubkörper befestigt ist, der mit einem Sockel über ein Scherengestänge verbunden ist.The invention relates to a patient table with a table frame on which a patient table is vertically adjustable, which is attached to a lifting body which is connected to a base via a pair of scissors.

Patientenlagerungstische dieser Art werden z.B. in der Angiographie zur Darstellung von Blutgefäßen verwendet. Dabei wird gewünscht, daß der Patient für den Arzt von allen Seiten gut zugänglich ist. Ferner soll die Patientenlagerungsplatte bei geringen Abmessungen des Tischgestelles weit abgesenkt werden können, damit eine leichte Umlagerung des Patienten von einem Bett auf den Patientenlagerungstisch möglich ist. Schließlich soll die Hubhöhe so groß sein, daß eine optimale Arbeitshöhe für den Arzt eingestellt werden kann.Patient positioning tables of this type are e.g. used in angiography to visualize blood vessels. It is desired that the patient is easily accessible to the doctor from all sides. Furthermore, the patient support plate should be able to be lowered far in the case of small dimensions of the table frame, so that the patient can easily be transferred from a bed to the patient support table. Finally, the lifting height should be so large that an optimal working height can be set for the doctor.

Ein Patientenlagerungstisch der eingangs genannten Arat ist in der DE-AS 15 66 654 beschrieben. Bei diesem bekannten Patientenlagerungstisch sind zwar die Länge und Breite des Tischgestelles relativ klein; wegen der Anlenkung des Scherengestänges am Boden des Sockels des Patientenlagerungstisches ist jedoch nur ein relativ kleiner Hub möglich.A patient table of the Arat mentioned is described in DE-AS 15 66 654. In this known patient table, the length and width of the table frame are relatively small; because of the articulation of the scissors linkage on the base of the base of the patient table, however, only a relatively small stroke is possible.

Der Erfindung liegt die Aufgabe zugrunde, einen Patientenlagerungstisch der eingangs genannten Art so auszubilden, daß mit einfachen Konstruktionselementen eine kleine Grundfläche des Tischgestelles, eine niedrige minimale Tischhöhe und eine optimale Arbeitshöhe erreichbar sind.The invention has for its object to design a patient table of the type mentioned so that with simple construction elements, a small footprint of the table frame, a low minimum table height and an optimal working height can be achieved.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß Hubkörper und Sockel aus ineinanderschiebbaren kastenförmigen Teilen bestehen, und daß das Scherengestänge an den einander zugewandten Enden des Hubkörpers und des Sockels angelenkt und derart ausgebildet ist, daß seine Arme aus der geschlossenen Strecklage nach beiden Seiten auslenkbar sind. Bei dem erfindungsgemäßen Patientenlagerungstisch liegt das Scherengestänge etwa horizontal, wenn das obere Ende des Sockels und das untere Ende des Hubkörpers etwa auf gleichem Niveau liegen. Von dieser Stellung aus kann das Scherengestänge nach beiden Richtungen verschwenkt werden, so daß einerseits ein Ineinanderschieben von Hubkörper und Sockel und andererseits eine Entfernung des Hubkörpers vom Sockel möglich ist, die durch die Abmessungen des Scherengestänges festgelegt ist. Die gesamte Hubhöhe ergibt sich demgemäß aus dem Hub des Scherengestänges, der von der Strecklage aus nach beiden Seiten möglich ist.This object is achieved in that the lifting body and base consist of nestable box-shaped parts, and that the scissor linkage is articulated at the mutually facing ends of the lifting body and the base and is designed such that its arms can be deflected from the closed stretched position on both sides. In the patient table according to the invention, the scissor linkage is approximately horizontal when the upper end of the base and the lower end of the lifting body are approximately at the same level. From this position, the scissor linkage can be pivoted in both directions, so that on the one hand a pushing together of the lifting body and base and on the other hand a removal of the lifting body from the base is possible, which is determined by the dimensions of the scissor linkage. The total lifting height is accordingly the result of the stroke of the scissor linkage, which is possible on both sides from the extended position.

Die Erfindung ist nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:

  • Fig. 1 eine Ansicht der für die Erfindung wesentlichen Teile eines Patientenlagerungstisches von oben, und
  • Fig. 2 und 3 eine Seitenansicht des Patientenlagerungstisches gemäß Figur 1 in seiner höchsten und tiefsten Stellung.
The invention is explained below with reference to an embodiment shown in the drawing. Show it:
  • Fig. 1 is a view of the essential parts of the invention of a patient table from above, and
  • 2 and 3 is a side view of the patient table according to Figure 1 in its highest and lowest position.

In der Ansicht gemäß Figur 1 ist die Patientenlagerungsplatte nicht dargestellt und nur das Tischgestell gezeichnet. Ein Sockel 1 trägt auf einer Achse 2 einen ersten Scherenarm 3. Ein zweiter Scherenarm, der aus zwei Tragteilen 4a und 4b besteht, ist über Kugellagerführungen 5a und 5b im Sockel 1 horizontal verschiebbar gelagert. Die Tragteile 4a, 4b sind über eine Welle 6 mit einander verbunden, mit der sie auch im Scherenarm 3 relativ zu diesem schwenkbar gelagert sind. Die Tragteile 4a, 4b sind an einem Hubkörper 7 mit Hilfe von Achsen 8a, 8b schwenkbar gelagert. Der Hubkörper 7 ist ferner durch Führungen 9a, 9b mit dem Scherenarm 3 horizontal verschiebbar verbunden.The patient positioning is in the view according to FIG plate not shown and only the table frame drawn. A base 1 carries a first scissor arm 3 on an axis 2. A second scissor arm, which consists of two supporting parts 4a and 4b, is mounted horizontally displaceably in the base 1 via ball bearing guides 5a and 5b. The supporting parts 4a, 4b are connected to one another via a shaft 6, with which they are also pivotably mounted in the scissor arm 3 relative to the latter. The supporting parts 4a, 4b are pivotally mounted on a lifting body 7 with the aid of axes 8a, 8b. The lifting body 7 is also connected to the scissor arm 3 so that it can be moved horizontally by guides 9a, 9b.

Aus den Figuren 2 und 3 ergibt sich, daß der Sockel 1 und der Hubkörper 7 aus ineinanderschiebbaren, kastenförmigen Teilen bestehen. Ein Ineinanderschieben ist möglich, weil diese Teile V-förmig ausgeschnitten sind. Die jeweils schmalere Führung des einen Teiles greift dabei in die breitere Führung des anderen Teiles ein. In der in der Figur 2 dargestellten, abgesenkten Stellung der Patientenlagerungsplatte 13 liegen die Führungen 9a, 9b innerhalb der Führungen 5a, 5b und die Achse 2 innerhalb der Achsen 8a, 8b. Die Welle 6 wird von den Teilen 1, 7 umgriffen.It can be seen from FIGS. 2 and 3 that the base 1 and the lifting body 7 consist of box-shaped parts which can be pushed into one another. Pushing one into the other is possible because these parts are cut out in a V-shape. The narrower guide of one part engages in the wider guide of the other part. In the lowered position of the patient support plate 13 shown in FIG. 2, the guides 9a, 9b lie within the guides 5a, 5b and the axis 2 within the axes 8a, 8b. Parts 1, 7 encompass shaft 6.

Als Hubantrieb ist ein Elektroschubmotor 10 vorgesehen, der unterhalb des Scherenarmes 3 an einer Achse 11 und am Sockel 1 an einer Achse 12 wirkt. Zur Unterstützung des Hubantriebes können an den gleichen Achsen Gasfedern 14 (Fig. 1) angreifen, die für eine mittlere Last ausgelegt sind und die notwendige Leistung des Hubantriebes verkleinern.An electric thrust motor 10 is provided as the lifting drive, which acts below the scissor arm 3 on an axis 11 and on the base 1 on an axis 12. To support the linear actuator, gas springs 14 (FIG. 1) can act on the same axes, which are designed for a medium load and reduce the necessary output of the linear actuator.

Zur Verminderung des Sicherheitsrisikos kann das gesamte Hubsystem durch Teleskoprohre oder Faltenbälge verkleidet sein.To reduce the safety risk, the entire lifting system can be covered by telescopic tubes or bellows.

Wesentlich ist, daß das Scherengestänge 3, 4a, 4b an den einander zugewandten Enden des Hubkörpers 7 und des Sokkels 1 angelenkt und derart ausgebildet ist, daß seine Arme 3, 4a, 4b aus der geschlossenen Strecklage nach beiden Seiten auslenkbar sind, so daß die Teile 1, 7 einerseits gemäß Figur 2 ineinanderschiebbar sind und andererseits ein großer maximaler Hub (Fig. 3) ermöglicht ist.It is essential that the scissors linkage 3, 4a, 4b are articulated at the mutually facing ends of the lifting body 7 and the base 1 and are designed such that its arms 3, 4a, 4b can be deflected from the closed stretched position on both sides, so that the Parts 1, 7, on the one hand, can be pushed into one another according to FIG. 2, and, on the other hand, a large maximum stroke (FIG. 3) is made possible.
