Taschen-EKGPocket ECG
Die Erfindung betrifft ein tragbares, batteriebetriebenes Taschen-EKG, insbesondere zur Patientenüberwachung und Sofortdiagnose bei Notfällen.The invention relates to a portable, battery-operated pocket EKG, in particular for patient monitoring and immediate diagnosis in emergencies.
Aus der US-PS 4,606,352 ist ein Taschen-EKG bekannt, daß einen Rechnerteil, Meßwerterfassung, Signalbearbeitung, Datenspeicherung, Eingabetastatur und Anzeigeeinrichtung umfaßt. Die Elektroden sind an der Gehäuseaußenseite angeordnet. Nachteilig bei diesem Gerät ist die fehlende Bedienerfreundlichkeit und die ungenügende Eignung für Notfälle.A pocket EKG is known from US Pat. No. 4,606,352, which comprises a computer part, measured value acquisition, signal processing, data storage, input keyboard and display device. The electrodes are arranged on the outside of the housing. The disadvantage of this device is the lack of user-friendliness and insufficient suitability for emergencies.
Aus der DE-PS 36 36 996 ist ebenfalls ein tragbares batteriebetriebens Herzdiagnosegerät bekannt, bei dem eine Elektrode als Halteclip ausgebildet ist.From DE-PS 36 36 996 a portable battery-operated cardiac diagnostic device is also known, in which an electrode is designed as a retaining clip.
Es ist Aufgabe der vorliegenden Erfindung, ein Taschen-EKG der bekannten Art so weiterzubilden, daß es besser für Notfälle geeignet ist.It is an object of the present invention to develop a pocket EKG of the known type so that it is better suited for emergencies.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1.This object is achieved by the features of claim 1.
Durch das Integrieren der Elektroden in den Batteriedeckel wird zum einen erreicht, daß der Elektrodenteil leicht ausgetauscht werden kann und zum anderen wird dadurch erreicht, daß die Zahl der abnehmbaren Teile am kompakten Taschen-EKG minimiert wird, da ein Batteriedeckel ohnehin vorhanden sein muß, um den Austausch der Batterie bzw. Akkus zu ermöglichen. Ein weiterer Vorteil besteht darin, daß durch die Abnehmbarkeit des Batteriedeckels mit den integrierten Elektroden die Reinigung der Elektroden erleichtert wird ohne Gefahr zu laufen, durch Reinigungsmittel die Elektronik des Taschen-EKG funk- tionsunfähig zu machen.By integrating the electrodes into the battery cover, on the one hand it is achieved that the electrode part can be easily replaced and on the other hand it is achieved in that the number of detachable parts on the compact pocket ECG is minimized, since a battery cover must already be present in order to to enable the replacement of the battery or accumulators. Another advantage is that The detachability of the battery cover with the integrated electrodes makes it easier to clean the electrodes without running the risk of making the electronics of the pocket EKG inoperative with cleaning agents.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung umfaßt das erfindungsgemäße Taschen-EKG ein Datenübertragungsmodul zum Übertragen der auf- gezeichneten Signale nach außen und zum Empfangen von Steuersignalen und sonstigen Daten. Hierbei ist insbesondere eine Schnittstelle, z.B. eine IR- Schnittstelle zu handelsüblichen Handys vorteilhaft. Damit kann beispielsweise ein Notfallarzt an einer Unfallstelle die EKG-Daten aufnehmen und direkt an die Notaufnahme eines Krankenhauses übermitteln. Auch im häuslichen Bereich bei der Selbstdiagnose kann der Patient die Daten aufnehmen und per Telefon oder Handy an seinen Arzt in der Praxis übermitteln. Dies vereinfacht die Nachsorge z.B. bei Infarktpatienten. Das Datenübertragungsmodul kann vorteilhafterweise ebenfalls in den Batteriedeckel integriert werden. Auf diese Weise kann ein und dasselbe Grundgerät mit unterschiedlichen Datenübertragungsmodulen versehen werden.According to an advantageous embodiment of the invention, the pocket EKG according to the invention comprises a data transmission module for transmitting the recorded signals to the outside and for receiving control signals and other data. An interface, e.g. an IR interface to commercially available cell phones is advantageous. This enables, for example, an emergency doctor to record the ECG data at an accident site and transmit it directly to the emergency department of a hospital. The patient can also record the data in the home with self-diagnosis and transmit it to his doctor in the practice by phone or cell phone. This simplifies aftercare e.g. in infarct patients. The data transmission module can advantageously also be integrated into the battery cover. In this way, one and the same basic device can be provided with different data transmission modules.

Fig. 3 zeigt die Ausführungsform nach Fig. 2 in einer Aufsicht auf den Geräteboden mit dem Batteriedeckel 32 und darin integrierten Elektroden 34, 35 und 36. Die Elektrode 34 ist hierbei als Halteclip ausgebildet. Der Batteriedeckel 32 weist einen Verschlußmechanismus 41 auf, durch den der Batteriedeckel 32 lösbar mit dem Gehäuse 1 verbunden ist .FIG. 3 shows the embodiment according to FIG. 2 in a top view of the device base with the battery cover 32 and electrodes 34, 35 and 36 integrated therein. The electrode 34 is designed as a retaining clip. The battery cover 32 has a locking mechanism 41 through which the battery cover 32 is detachably connected to the housing 1.
Fig. 4 zeigt eine Querschnittansicht des Gerätes nach Fig. 2 bzw. 3 mit dem Batteriedeckel 32, der Meßwerterfassung 26, dem Rechnerteil 2 und der Stromversorgung 24 und der Datenübertragungseinheit 38, die in der Ausführungsform nach Fig. 5 als in den Batteriedeckel 32 integriert dargestellt ist. Die Datenübertragungseinheit 38 kann jedoch auch in dem Gehäuse 1 angeordnet sein. Weiter umfaßt der Batteriedeckel 32 eine Kontaktiereinheit 40, die die elektrische Verbindung der Elektroden 34, 35 und 36 zu der Meßwerterfassung 26 in dem Gehäuse 1 herstellt.FIG. 4 shows a cross-sectional view of the device according to FIGS. 2 and 3 with the battery cover 32, the measured value acquisition 26, the computer part 2 and the power supply 24 and the data transmission unit 38, which in the embodiment according to FIG. 5 is integrated in the battery cover 32 is shown. The data transmission unit 38 can, however, also in the Housing 1 may be arranged.

Fig. 5 zeigt ein schematisches Blockschaltbild mit den den Funktionen des Batteriedeckels 32. Die Kontaktiereinrichtung 40 bildet zusammen mit dem Verschlußmechanismus 41 eine Ein/Aus-Schalter 42. Durch die Kontaktiereinrichtung 40 werden die Ableitelektroden 34, 35 und 36 mit der Meßwerterfassung 26 und dem Rechnerteil 2 verbunden. Beim Verschließen des Batteriedeckels 32 wird die interne Stromversorgung 24 automatisch aktiviert bzw. beim Öffnen des Batteriedeckels 32 wird das Gerät stromlos geschaltet. D.h., wenn der Batteriedeckel 32 offen ist, ist das Gerät vollständig stromlos, so daß problemlos die Batterien gewechselt werden können. Das Gerät ist nur bei geschlossenem Batteriedeckel 32 funktionsfähig und mit Strom versorgt und damit auch dicht. Stromfluß bei offenen und damit undichtem Gerät kann daher nicht auftreten, was einen erheblichen Sicherheitsvorteil bedeutet .Fig. 5 shows a schematic block diagram with the functions of the battery cover 32. The contacting device 40 together with the locking mechanism 41 forms an on / off switch 42. Through the contacting device 40, the lead electrodes 34, 35 and 36 with the measured value acquisition 26 and the Computer part 2 connected. When the battery cover 32 is closed, the internal power supply 24 is automatically activated, or when the battery cover 32 is opened, the device is switched off. That is, when the battery cover 32 is open, the device is completely de-energized so that the batteries can be changed without any problems. The device is only functional and is supplied with current when the battery cover 32 is closed, and is therefore leakproof. Current flow when the device is open and therefore leaky cannot occur, which means a considerable safety advantage.
