Abstract

A cable connector (18) and, if required, partially also the apparatus itself, are provided with an electronic coding (U0, 16, 17, 27) characterising the type of electrode used. A coding reader and comparison unit (3) reads the connector coding and compares it to a nominal value stored in a memory (4). If the two values differ, a signal (12, 13) suppressing operation is produced. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Anordnung von einem einen Reizsignalerzeuger umfassenden Reizstromgerät, insbesondere für Reizstromtherapie an einem Patienten, und einem eine Verbindung mit Reizstromelektroden herstellenden Kabelstecker.The invention relates to an arrangement of a stimulation current device comprising a stimulation signal generator, in particular for stimulation current therapy on a patient, and a cable plug which produces a connection with stimulation current electrodes.

Anordnungen mit Reizstromgeräten dieser Art können bekanntlich einkreisig, mehrkreisig oder mit Handgriff betrieben werden. Manche Geräte sind dabei in der Betriebsart umschaltbar (z.B. einkreisig, mehrkreisig). Andere müssen nebeneinander betrieben werden. Auf jeden Fall muß sichergestellt sein, daß für eine bestimmte Betriebsart auch immer nur die passende Elektrodenart und keine andere am Gerät angeschlossen wird. Wenn gar keine Elektrode angeschlossen ist, soll ebenfalls verhindert werden, daß der Elektrodenanschluß unter Spannung steht.Arrangements with stimulation current devices of this type can, as is known, be operated in single-circuit, multi-circuit or with handle. Some devices can be switched in the operating mode (e.g. single-circuit, multi-circuit). Others have to be operated side by side. In any case, it must be ensured that only the right type of electrode and no other type is connected to the device for a certain operating mode. If no electrode is connected at all, the electrode connection should also be prevented from being live.

Aus der EP-A-0 070 674 ist eine Katheteranschlußverbindung an einem elektronischen Gerät bekannt, dessen einer Teil mit einem äußeren Apparat durch einen Kabelstecker verbindbar ist. Der Kabelstecker ist mit einer den äußeren Apparat oder den Stecker kennzeichnenden elektronischen Kodierung versehen und einem Dekodierer zugeordnet, der ein von der gelesenen Kodierung abhängiges Signal erzeugt. Die Kodierung wird durch drei leitende Brücken an Kontakten im Kabelstecker bewirkt, wobei ein Kontakt mit Massepotential verbindbar ist. Dadurch können nur äußerlich unterschiedliche Katheter mittels eines einem Computer zugeleiteten entsprechenden Erkennungssignals erkannt werden.EP-A-0 070 674 discloses a catheter connection on an electronic device, part of which can be connected to an external apparatus by means of a cable connector. The cable connector is provided with an electronic coding which characterizes the external apparatus or the connector and is assigned to a decoder which generates a signal which is dependent on the coding read. The coding is effected by three conductive bridges on contacts in the cable connector, whereby a contact with ground potential can be connected. As a result, only externally different catheters can be recognized by means of a corresponding identification signal supplied to a computer.

Aufgabe vorliegender Erfindung ist es, eine Anordnung mit einem Reizstromgerät aufzubauen, das bei Anschluß einer betriebsfremden Elektrode sowie auch dann, wenn gar keine Elektrode angeschaltet ist, mit Nichtbetriebsbereitschaft reagiert.The object of the present invention is to set up an arrangement with an electrical stimulation device which, when a non-operational device is connected Electrode reacts with non-operational readiness, even when no electrode is switched on.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.The object is achieved by the features of claim 1.

Vergißt man den Kabelstecker einzustecken oder schließt man einen Stecker mit einer falschen Elektrode an, so reagiert jetzt das Gerät in der erfindungsgemäßen Weise durch Betriebsunterdrückung (Der innere Stromkreis wird abgeschaltet).If you forget to plug in the cable connector or connect a connector with the wrong electrode, the device now reacts in the manner according to the invention by suppressing operation (the inner circuit is switched off).

Vorzugsweise wird gemäß Anspruch 2 zusätzlich noch ein optischer und/oder akustischer Alarm erzeugt, um die Person, die das Gerät bedient, auf den Mißstand hinzuweisen.An optical and / or acoustic alarm is preferably additionally generated according to claim 2, in order to inform the person operating the device of the maladministration.

Eine weitere vorteilhafte Ausgestaltung der Erfindung ergibt sich aus Anspruch 3. Hier erkennt das Gerät Stecker verschiedener zugelassener Elektrodenarten und schaltet automatisch auf die jeweils mit Stecker vorgewählte Elektrodenbetriebsart um.A further advantageous embodiment of the invention results from claim 3. Here, the device recognizes plugs of different approved electrode types and automatically switches to the electrode operating mode preselected in each case with the plug.

Eine vorteilhafte Ausgestaltung der Kodierung ergibt sich aus Anspruch 4.An advantageous embodiment of the coding results from claim 4.

Weitere Vorteile und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen anhand der Zeichnung und in Verbindung mit den restlichen Unteransprüchen.Further advantages and details of the invention emerge from the following description of exemplary embodiments with reference to the drawing and in conjunction with the remaining subclaims.

Fig. 1
1 shows an arrangement with an electrical stimulation device according to the invention in the basic circuit diagram,
Fig. 2
an embodiment of a coding that indicates when a connector was accidentally not plugged in, and
Fig. 3
to 5 exemplary embodiments for plug coding for single-circuit, multi-circuit and handle operation of the device according to FIG. 1.

In der Fig. 1 umfaßt die Anordnung unter anderem ein Reizstromgerät 1, einen Reizsignalerzeuger 2, einen Mikroprozessor 3, ein EPROM 4, einen digitalen Eingang 5 und einen optischen und akustischen Signalerzeuger 6. Das Reizstromgerät 1 besitzt fünf Steckbuchsen 7 bis 11.1, the arrangement includes, inter alia, an electrical stimulation device 1, an electrical stimulation signal generator 2, a microprocessor 3, an EPROM 4, a digital input 5 and an optical and acoustic signal generator 6. The electrical stimulation device 1 has five sockets 7 to 11.

Die Steckbuchsen 7 und 8 sind über Relaisschaltkontakte 12, 13 mit dem Stromausgang 14, 15 des Reizsignalerzeugers 2 verbindbar. Die Steckbuchse 9 liegt an Masse. Die beiden restlichen Steckbuchsen 10 und 11 sind einerseits über ohmsche Widerstände 16, 17 an die Spannung UO= +5V geschaltet und bilden andererseits die Eingangsbuchsen des digitalen Eingangs 5.The sockets 7 and 8 can be connected via relay switch contacts 12, 13 to the current output 14, 15 of the stimulus signal generator 2. The socket 9 is grounded. The other two Sockets 10 and 11 are connected to the voltage U O = + 5V on the one hand via ohmic resistors 16, 17 and on the other hand form the input sockets of the digital input 5.

Der in Fig. 1 mit 18 bezeichnete angesteckte Kabelstecker umfaßt Steckkontakte 19 bis 23, die zu den Steckbuchsen 7 bis 11 des Reizstromgerätes 1 passen. Die Steckkontakte 19 und 20 sind dabei mit den Stomführungsleitungen 24, 25 zu den Reizstromelektroden (nicht dargestellt) über das Kabel 26 verbunden. Die Steckkontakte 21 und 22 sind mit einer Brücke 27 versehen. Diese Brücke 27, die das Massepotential auf die Steckbuchse 10 legt, während an der Steckbuchse 11, in der der unverbundene Steckkontakt 23 steckt, über den Widerstand 17 positives Potential anliegt, stellt eine erste Möglichkeit für eine Steckerkodierung mit insgesamt drei zusätzlichen Kontakten dar. Die Kodierung mit logisch 0, 1 für den digitalen Eingang 5, die in Fig. 3 nochmals vergrößert dargestellt ist, steht z.B. für einkreisigen Betrieb.The plug-in cable connector designated 18 in FIG. 1 comprises plug contacts 19 to 23 which match the sockets 7 to 11 of the stimulation current device 1. The plug contacts 19 and 20 are connected to the power supply lines 24, 25 to the stimulation current electrodes (not shown) via the cable 26. The plug contacts 21 and 22 are provided with a bridge 27. This bridge 27, which places the ground potential on the socket 10, while at the socket 11, in which the unconnected plug contact 23 is connected, via the resistor 17 there is positive potential, represents a first possibility for a plug coding with a total of three additional contacts Coding with logic 0, 1 for the digital input 5, which is shown again enlarged in FIG. 3, stands for example for single-circuit operation.

Zwei weitere Kodierungen für z.B. Handgriff-Betrieb und mehrkreisigen Betrieb zeigen die Kabelstecker 28 und 29 der Fig. 4 und 5. Im Kabelstecker 28 der Fig. 4 liegt z.B. eine Brücke 30 zwischen den Steckkontakten 21 und 23. Die Steckbuchse 10 liegt jetzt also auf logisch 1, während die Steckbuchse 11 auf logisch 0 liegt.Two further codes for e.g. Handle operation and multi-circuit operation are shown by the cable connectors 28 and 29 in FIGS. 4 and 5. In the cable connector 28 in FIG. a bridge 30 between the plug contacts 21 and 23. The socket 10 is now at logic 1, while the socket 11 is at logic 0.

Im Kabelstecker 29 sind alle drei Steckkontakte 21, 22 und 23 durch die Brücke 31 überbrückt. Beide Steckbuchsen 10 und 11 liegen jetzt also auf logisch 0.In the cable connector 29, all three plug contacts 21, 22 and 23 are bridged by the bridge 31. Both sockets 10 and 11 are now at logical 0.

Die logische Kombination 1, 1 an den Steckbuchsen 10, 11 ergibt sich, wenn kein Kabelstecker angesteckt ist. Diese Kodierung meldet also den fehlenden Steckkontakt. Im Zusammenhang mit dem Prinzipschaltbild der Fig. 1 ergibt sich jetzt also folgende Funktionsweise:The logical combination 1, 1 at the sockets 10, 11 results when no cable connector is connected. This coding thus reports the missing plug contact. In connection with the basic circuit diagram of FIG. 1 results So now the following functionality:

1. Nicht angesteckter Stecker1. Unplugged connector

Der Mikroprozessor 3 liest vom digitalen Eingang 5 über die Leitung 32 die Kodierung 1, 1 und vergleicht diese über die Leitungen 33, 34 mit dem im EPROM 4 gespeicherten Sollwert. Da der Sollwert 1, 1 nicht gespeichert ist, erzeugt der Mikroprozessor auf der Leitung 35 ein Signal, das einerseits über die Leitung 36 die Relaiskontakte 12, 13 öffnet (gestrichelte Schaltstellung), und andererseits über die Leitung 37 den optischen und akustischen Signalerzeuger 6 aktiviert. Die Steckbuchsen 7 und 8 führen also keine Spannung und der optische und akustische Alarm zeigt an, daß mit dem Stecker etwas nicht in Ordnung ist. (Hier Stecker nicht angesteckt).The microprocessor 3 reads the coding 1, 1 from the digital input 5 via the line 32 and compares this via the lines 33, 34 with the target value stored in the EPROM 4. Since the setpoint 1, 1 is not stored, the microprocessor generates a signal on line 35, which on the one hand opens the relay contacts 12, 13 via line 36 (dashed switch position), and on the other hand activates the optical and acoustic signal generator 6 via line 37 . The sockets 7 and 8 are therefore not live and the visual and acoustic alarm indicates that something is wrong with the plug. (Plug not plugged in here).

2. Falscher Stecker angesteckt2. Wrong plug inserted

Im EPROM 4 sei z.B. der Sollwert 0,1 (einkreisiger Betrieb) eingespeichert. Wird jetzt z.B. versehentlich einer der Stecker 28, 29 der Fig. 4 bzw. 5 angesteckt, so ergibt sich derselbe Funktionsablauf wie zuvor für die Kombination 1,1. Der Mikroprozessor 3 findet also keinen Sollwert 1,0 bzw. 0,0 im EPROM 4. Er erzeugt daraufhin wieder ein Signal am Ausgang 35 zur Öffnung der Relaiskontakte 12 und 13 bzw. zur optischen und akustischen Alarmgebung am Alarmerzeuger 6.For example, in EPROM 4 the setpoint 0.1 (single-circuit operation) is saved. Now e.g. 4 or 5 is inadvertently plugged in, the same functional sequence results as before for the combination 1, 1. The microprocessor 3 therefore does not find a setpoint 1.0 or 0.0 in the EPROM 4. It then generates a signal at the output 35 for opening the relay contacts 12 and 13 or for visual and acoustic alarming on the alarm generator 6.

3. Richtiger Stecker gesteckt3. Correct plug inserted

Der richtige Wert sei 0,1. Wird also der Stecker 18 angesteckt, so liest der Mikroprozessor 3 die Kombination 0,1. Da diese als Sollwert im EPROM 4 gespeichert ist, erzeugt der Mikroprozessor 3 an seinem Ausgang 35 kein Signal. Die Relaiskontakte 12, 13 können schließen und es wird auch kein optischer und akustischer Alarm erzeugt. Das Gerät ist jetzt betriebsbereit.The correct value is 0.1. If the plug 18 is plugged in, the microprocessor 3 reads the combination 0.1. Since this is stored as a setpoint in the EPROM 4, the microprocessor 3 generates no signal at its output 35. The relay contacts 12, 13 can close and no visual and acoustic alarm is generated. The device is now ready for use.

Denkbar ist auch, daß in ein und demselben Reizstromgerät mehrere Betriebsabläufe für verschiedene Betriebsarten einprogrammiert sind. In einem solchen Falle können unterschiedliche Stecker mit unterschiedlichen Kodierungen dazu verwendet werden, den Programmablauf entsprechend selbsttätig (z.B. über Mikroprozessor) umzuschalten. Hier akzeptiert das Gerät also unterschiedliche Kodierungen und schaltet lediglich dementsprechend um.It is also conceivable that several operating sequences for different operating modes are programmed into one and the same stimulation current device. In such a case, different plugs with different codes can be used to automatically switch the program sequence accordingly (e.g. via a microprocessor). Here, the device accepts different codes and only switches accordingly.

Der Mikroprozessor 3 steuert den Reizsignalerzeuger auch noch über einen Bus 38.The microprocessor 3 also controls the stimulus signal generator via a bus 38.
