Description

Die Erfindung betrifft ein fernbedienbares medizinisches Gerät gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a remotely controllable medical device according to the preamble of the patent claim 1.

Es ist bereits ein Röntgenuntersuchungsgerät bekannt, bei dem die Steuerelemente zur Auslösung der Gerätefunktionen in einem kleinen separaten, mit einem Kabel mit dem Röntgenuntersuchungsgerät verbundenen Bedienkästchen zusammengefaßt untergebracht sind. Diese Konstruktion erlaubt es, das Röntgenuntersuchungsgerät innerhalb der Reichweite des Kabels von einem beliebigen Ort aus zu steuern. Diese Konstruktion bringt es aber mit sich, daß das am Boden herumliegende Kabel eine ständige Stolpergefahr darstellt und das Vorbeifahren von Gegenständen jeglicher Art, wie z.B. von Krankenliegen, behindert Außerdem verschmutzt das am Boden herumliegende Kabel mit der Zeit Dies ist um so gravierender, als das Kabel die Abgenzung zwischen unsterilen (Fußboden) und sterilen Bereich (Bedienfläche) durchbrichtThere is already an X-ray examination device known in which the controls for triggering the Device functions in a small, separate, cable connected to the X-ray examination device Control boxes are housed together. This construction allows the X-ray examination device controlled from anywhere within the reach of the cable. This construction but it brings with it that the cable lying around on the floor represents a constant risk of tripping and The passing of objects of any kind, such as sick beds, is a hindrance. In addition, it is dirty the cable lying around on the floor over time This is all the more serious than the cable dying The gap between the unsterile (floor) and sterile area (control surface) breaks through

Es ist aus der DE-OS 27 47407 eine Röntgendiagnostikanlage mit einer Bedienungseinrichtung zur Fernsteuerung der Röntgendiagnostikanlage bekannt Durch sie können auch durch einen Infrarotsender die Steuerbefehle zur Röntgendiagnostikeinrichtung übertragen werden. Die Steuerbefehle werden nacheinander durch Betätigung der Bedienungselemente der Röntgendiagnostikanlage übermittelt Spezielle Verknüpfungslogiken oder Verriegelungseinrichtungen verhindern, daß bei gleichzeitiger Betätigung mehrerer Tasten Steuerbefehle ausgesandt werden. Dadurch lassen sich durch den Sender nicht mehrere Steuerbefehle gleichzeitig übertragen, so daß dadurch die Funktionalität und die Betriebssicherheit des Gerätes eingeschränkt sind.It is from DE-OS 27 47407 an X-ray diagnostic system known with an operating device for remote control of the X-ray diagnostic system They can also use an infrared transmitter to transmit the control commands to the X-ray diagnostic device will. The control commands are issued one after the other by actuating the operating elements of the X-ray diagnostic system transmits special linkage logics or interlocking devices prevent that when several buttons are pressed at the same time, control commands are sent out. This allows the transmitter does not transmit several control commands at the same time, so that the functionality and the operational safety of the device is limited.

Die Erfindung geht von der Aufgabe aus, ein fernbedienbares medizinisches Gerät gemäß dem Oberbegriff des Patentanspruchs 1 derart auszubilden, daß das Bedienkästchen den Erfordernissen im Hinblick auf Funktionalität und Sicherheit auch im Operationssaal voll genügt.The invention is based on the object of providing a remotely controllable medical device according to the preamble of claim 1 in such a way that the control box meets the requirements in terms of functionality and security in the operating theater is fully sufficient.

Die Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Maßnahmen gelöst. Diese ermöglichen es, mit einem Sender auszukommen, mit dem nur auf einem Kanal gleichzeitig gesendet werden kann. Dadurch können teure Zeitmultiplexeinrichtungen eingespart werden und trotzdem lassen sich sowohl einzelne Steuerfunktionen als auch mehrere gleichzeitig ablaufende Steuerfunktionen gemeinsam veranlassen. Dieses ist insbesondere deshalb von Bedeutung, weil man in der Medizintechnik unter Umständen gezwungen ist, bestimmte Gerätefunktionen einmal einzeln und einmal gemeinsam mit anderen Gerätefunktionen ablaufen zu lassen.The object is achieved according to the invention by what is specified in the characterizing part of claim 1 Measures resolved. These make it possible to get along with one transmitter, with the only one Channel can be sent at the same time. In this way, expensive time division multiplex devices can be saved and yet both individual control functions and several simultaneously running Initiate control functions together. This is particularly important because the Medical technology may be forced to perform certain device functions individually and once to run together with other device functions.

Es läßt sich ein bekannter Kodier-Schaltkreis mit Spalten- und Zeileneingängen zum Anschluß der Bedienungselemente verwenden, wenn den in den Spalten angeordneten Bedienungselementen über das für die Kombination von Steuerbefehlen vorgesehene Bedienungselement verschiedene Spalteneingänge zugeordnet sind.
Die Betriebssicherheit des fernbedienbaren medizinisehen Gerätes läßt sich wesentlich erhöhen, wenn das Bedienkästchen in zweckmäßiger Weiterbildung der Erfindung nur an bestimmten, hierfür vorgesehenen Orten einschaltbar ist.
Eine solche Maßnahme erlaubt es, die Bedienung auf jene Orte zu begrenzen, die einen Blickkontakt auf das medizinische Gerät bzw. auf den Patienten, der mit dem Gerät untersucht bzw. behandelt wird, ermöglicht.A known coding circuit with column and row inputs can be used to connect the operating elements if the operating elements arranged in the columns are assigned different column inputs via the operating element provided for the combination of control commands.
The operational safety of the remotely controllable medical device can be significantly increased if, in an expedient development of the invention, the control box can only be switched on at certain locations provided for this purpose.
Such a measure makes it possible to limit the operation to those locations which allow eye contact to the medical device or to the patient who is being examined or treated with the device.

In zweckmäßiger Ausgestaltung der Erfindung kann an den für die Bedienung vorgesehenen Orten ein mit einer Gegenfläche des Bedienkästchens in Eingriff bringbares und einen Euisciiaiiei betätigendes Siciiclcment vorhanden sein. Mit einem solchen Stellelement läßt sich ein Steuerbefehl an den zugelassenen Bedienorten vornehmen, der das Bedienungskästchen in einen betriebsbereiten Zustand versetzt und anderenorts nicht vorzunehmen ist.In an expedient embodiment of the invention, a can be used at the locations provided for operation a counter surface of the control box can be brought into engagement and a safety actuating element to be available. With such an adjusting element, a control command can be sent to the approved operating locations which puts the control box in an operational state and elsewhere is not to be undertaken.

In einer anderen, besonders zweckmäßigen Ausgestaltung der Erfindung kann an den für die BedienungIn another, particularly expedient embodiment of the invention, the for operation

vorgesehenen Orten ein Permanentmagnet vorgesehen sein, der bei Annäherung einen im Bedienkästchen angebrachten Reedkontakt betätigt Das magnetische Feld des Permanentmagneten läßt sich in einfachster Weise an den beliebigen Stellen der zugelassenen Bedienungsorte, wie z. B. an Tischen, Ablageborden, Konsolen, in Fußböden, usw. anbringen. Dabei ist eine exakte Positionierung oder gar Ausrichtung des Bedienkästchens zum Magneten nicht erforderlich.Provided places a permanent magnet can be provided, which is attached to the control box when approaching Reed contact actuated The magnetic field of the permanent magnet is very simple Way at any point of the approved operating locations, such. B. on tables, shelves, consoles, Install in floors, etc. This includes an exact positioning or even alignment of the control box to the magnet not required.

Die Betriebssicherheit des medizinischen Gerätes läßt sich weiter erhöhen, wenn mehrere untereinander parallel geschaltete Infrarotsender an verschiedenen Seiten des Gehäuses des Bedienkästchens angeordnet sind. Dadurch läßt sich erreichen, daß die Übertragung der Steuerbefehle aus verschiedenen Richtungen ohne vorherige Ausrichtung des Bedienkästchens ermöglicht wird.The operational safety of the medical device can be further increased if several of them are connected to one another Infrared transmitters connected in parallel are arranged on different sides of the control box housing are. In this way it can be achieved that the transmission of the control commands from different directions without prior alignment of the control box is enabled.

In der Seitenansicht der F i g. 2 erkennt man den Aufbau des Bedienkästchens 1 und der Konsole 17. Das Bedienkästchen trägt auf seiner Oberseite 12 die Bedienungselemente 8,9,10,11 und an seiner einen rückwärtigen Stirnseite i3 die zwei Einhängeiasc'neii 14,15, mii denen es an einem Bügel 16, 18 eingehängt werden kann. Unterhalb der Einhängelaschen ist, wie die F i g. 2 zeigt, ein Puffer 28 am Gehäuse des Bedienkästchens 1 angebracht, mit dem sich das am Bügel eingehängte Bedienkästchen unterhalb des jeweiligen Bügels an der Wand abstützen kann. Im Innern des Bedienkästchens ist durch den Durchbruch in der Gchäusewand ein kleiner Akkumulator 29 für die interne Stromversorgung und eine Schaltanordnung 30, die die Infrarotsender 23, 24, 25 in einer Abhängigkeit von denen mit den Bedienungselementen 8, 9,10,11 gegebenen Steuerbefehlen steuert Im Bedienkästchen ist ferner ein Nockenschalter 31 eingebaut, dessen Stellglied 32 an der Innenseite der einen Einhängelasche 14 herausgeführt ist Am Boden des Bedienkästchens befindet sich e.;n ReedkontaktIn the side view of FIG. 2 shows the structure of the control box 1 and the console 17. The control box carries the control elements 8, 9, 10, 11 on its top 12 and the two hook-in buttons 14, 15 on its one rear end face i3, with which it is attached to one Brackets 16, 18 can be hung. As shown in FIG. 2 shows a buffer 28 attached to the housing of the control box 1, with which the control box suspended from the bracket can be supported on the wall below the respective bracket. Inside the control box is a small accumulator 29 for the internal power supply and a switching arrangement 30, which controls the infrared transmitters 23, 24, 25 depending on the control commands given with the control elements 8, 9, 10, 11 through the opening in the housing wall A cam switch 31 is also installed in the control box, the actuator 32 of which is led out on the inside of the one hanging tab 14. At the bottom of the control box there is e. ; n reed contact

ίο 33, der parallel zum Nockenschalter 31 geschaltet istίο 33, which is connected in parallel to the cam switch 31

Die Konsole 17, im wesentlichen eine auf einem verbreiterten Fuß 34 stehende Säule 35, auf der ein kleines rechteckiges Gehäuse 36 befestigt ist, trägt an der einen Stirnseite des Gehäuses 36 den Bügel 16, in dem die Einhängelaschen 14,15 des Bedienkästchens eingreifen können. Im Innern des Gehäuses 36 ist eine Speisespannungsquelle 37 aufgebaut die an je einem federnden Kontakt 38 (nur einer dargestellt) angeschlossen ist der im Bereich der beiden in den Bügel 16 eingehängten Einhängelaschen 14, 15 des eingehängten Bedienungskästchens 1 aus dem Gehäuse 36 herausragen. The console 17, essentially a column 35 standing on a widened foot 34 on which a small rectangular housing 36 is attached, carries on one end face of the housing 36, the bracket 16 in which the Hanging tabs 14,15 of the control box can intervene. Inside the housing 36 is a supply voltage source 37 constructed which is connected to a resilient contact 38 (only one shown) in the area of the two suspension lugs 14, 15 of the suspended control box 1 suspended in the bracket 16 protrude from the housing 36.

Die F i g. 3 zeigt den Aufbau der Schaltanordnung 30 für die Steuerung des Sendegerätes 39 der Sender 23, 24, 25 des Bedienkästchens 1 in Abhängigkeit von den Bedienungselementen 8,9,10,11. Hierzu ist ein handelsüblicher Schaltkreis 40 (PMOS-SAB 3210) verwendet, der in Abhängigkeit von je einem an einem der Spalteneingänge Si... Sn und einem der Zeileneingänge Z\... Zn anliegenden Potential am Ausgang eine binäre Zahl bildet, die über einen ebenfalls handelsüblichen binären Schalter 41 den entsprechenden Kanal des Sendegerätes 39 schaltet. Um eine möglichst große Zahl von Steuerbefehlen übertragen zu können, sind die jedem der auf dem Bedienkästchen 1 zweidimensional verschiebbaren Bedienungselemente 9, 10, 11 zugeordneten Schalter nach Art einer Matrix angeordnet. Auf diese Weise ist jeder einzelne dieser zwölf Schalter durch eine ganz bestimmte Zuordnung eines der S3... Sn Eingänge zu einem der Z\...Zn Eingänge bestimmt. Damit entspricht ihm auch eine ganz bestimmte binäre Zahl am Ausgang des binären Schalters 41.The F i g. 3 shows the structure of the switching arrangement 30 for controlling the transmitter 39 of the transmitters 23, 24, 25 of the control box 1 as a function of the control elements 8, 9, 10, 11. A commercially available circuit 40 (PMOS-SAB 3210) is used for this purpose, which forms a binary number at the output depending on a potential applied to one of the column inputs Si ... S n and one of the row inputs Z \ ... Z n, which switches the corresponding channel of the transmitter 39 via a likewise commercially available binary switch 41. In order to be able to transmit as large a number of control commands as possible, the switches assigned to each of the operating elements 9, 10, 11 which can be displaced two-dimensionally on the operating box 1 are arranged in the manner of a matrix. In this way, each of these twelve switches is determined by a very specific assignment of one of the S 3 ... S n inputs to one of the Z \ ... Z n inputs. A very specific binary number at the output of the binary switch 41 thus also corresponds to it.

Weil der Schaltkreis 40 jeweils nur eine einzige Zuordnung eines der Eingänge S\. .. Sn zu einem einzigen der Eingänge Zi... Zn und somit auch nur eine einzige Schalterfunktion gleichzeitig verarbeiten kann, im medizinischen Betrieb bestimmte Steuerbefehle aber auch gemeinsam mit anderen Steuerbefehlen ausführbar sein müssen, ist das Bedienungselement 8, welches zusammen mit je einer Schaltfunktion eines der anderen Bedienungselemente 9, 10, 11 betätigbar sein muß, entsprechend seinen drei Schaltzuständen an drei verschiedene Spalten Si, S2, S3 angeschlossen. Dadurch sind für dieses Bedienungselement 8 entsprechend seinen drei Schaltzuständen: »keine Durchleuchtung«, »Durchleuchtung« und »Aufnahme« am Eingang des Schaltkreises 40 drei Eingänge Si, S2, S3 reserviert, die zusammen mit jedem der übrigen Schalter geschaltet werden können.
Werden nun die Bedienungselemente des Bedienkästchens 1 betätigt, so werden von ihnen je eine der Spalten (S\... Sn) und Zeilen (Zt... Zn) miteinander verbunden, jede dieser möglichen SchaltsrstcHur.ger. entspricht einer binären Zahl am Ausgang des Schaltkreises 40 und einer bestimmten, einen bestimmten Kanal des Sendegerätes 39 wählende Schalterstellung des binären Schalters 41. Dabei ist es, wie am Beispiel des Aufnahmeschalters 8 gezeigt wurde, möglich, mit einem Sendekanal gleichzeitig mehrere Schaltfunktionen an-Because the circuit 40 only has a single assignment of one of the inputs S \. .. S n to a single one of the inputs Zi ... Z n and thus can process only a single switch function at the same time, but in medical operation certain control commands must also be executable together with other control commands, is the operating element 8, which together with each a switching function of one of the other operating elements 9, 10, 11 must be operable, connected to three different columns Si, S2, S3 according to its three switching states. As a result, three inputs Si, S2, S3 are reserved for this control element 8 according to its three switching states: "no fluoroscopy", "fluoroscopy" and "recording" at the input of the circuit 40, which can be switched together with each of the other switches.
If the control elements of control box 1 are now activated, one of the columns (S \ ... S n ) and rows (Zt ... Z n ) are connected to one another, each of these possible switchgear. corresponds to a binary number at the output of the circuit 40 and a specific switch position of the binary switch 41 that selects a specific channel of the transmitter 39. As shown in the example of the recording switch 8, it is possible to simultaneously activate several switching functions with one transmission channel.
